Hello everybody, Andrew and Maeski here with Dental L. So let's have a little chat together. Let's just talk about the never ending paperwork that I seem to have to do in my practice. Does anybody else feel like this or is it only me? Now I felt that it was never ending before because I did not have a dental software so anytime that I sent claims to insurance it would be by paper, which is annoying as heck. And trust me though, when I got my dental, my dental software, dental hygiene software I should say, DomeTrack, they're amazing. I hope I'm pronouncing their company name properly. But it has saved me a ton of time but I'm still doing so much work but it's my own fault because I tend to put these off and then a bunch kind of comes onto my plate and then I feel like I have to do it all. So I have some little tips for everybody. You might be doing this or maybe not, I don't know. But so this is more for people who have their practice and aren't hiring anybody else to kind of help them. I would love to hire somebody but I'm a control freak so I'm just not at that stage of the game yet.  Number one is do things as they come. And I say this meaning, let's say you're seeing three patients that day. Do your notes after every single patient. Do not wait to do your treatment notes until the end of the day because you will forget. I always forget. Take the time. If you're behind for your next patient, so be it. That's okay. Do those notes after every single patient. Again, just do as much as you can for that patient at that time. Now I do have a mobile hygiene practice so I go to patients houses plus I see patients in my own home too but primarily at the moment it seems to be all mobile hygiene. So where I'm getting at is I do all of my charting by my Apple watch. So I actually click the record feature and I do charting that way. And then when I come home, I listen to it and do charting for the odontogram or just simply whatever I had talked about. But what I've been doing is I have not been doing it as soon as I get home because I'm exhausted. So I will wait until the next day but then I'm tired again.  When I finally get around to it, there's like 10 patients where I have to fill in the odontogram for. So don't be like me. Do it after every patient, okay? So I'm kind of reminding myself of this as I'm talking about it. Do it after every patient. Even as I'm saying this, I have three patients that I have to do from yesterday because I was too tired when I came home. Okay, anyways, insurance stuff. If you are that nice person like I am, that actually helps your patients and sends everything through to insurance for them and they only have to pay the difference. That means extra paperwork. Kind of the same thing from point number one is just do everything as it comes. Send everything through to their insurance right away.  If you know that you're seeing say three patients that week with sunlight insurance, maybe wait until the end of the week to put all of those claims through, those paper claims since we cannot send electronically, but those paper claims through the one envelope.   That's just kind of what I've been doing and that does sort of help me manage my time a little bit. But don't wait two weeks or three weeks because then you don't get paid, right? Another tip for you that I had thought that I was always super organized, but it's the same type of thing where I put things off and put things off. Meaning if patients have secondary insurance, write that down somewhere. Whether it be in your computer software where it sends you a reminder in a month's time to check to see if that claim form from their primary insurance has come back. So then you can send to the secondary, okay? Have a reminder for yourself. Because when I first started, I didn't think that I would have as many patients as I do. So a good problem to have, but I just assumed that I would remember everybody who has secondary insurance and then send it through that way. Don't ask me why I thought that, but it doesn't happen. So make a note somewhere of those patients that you see that have secondary insurance so you can check and then submit it right away. Because I'm still finding patients from like September that I forgot to send it through to the secondary. So that's money on the table that I could have, right? So make sure to do that. Another thing, which I'm still not doing, so I'm kind of a hypocrite right now, but it was because I didn't know how. But what you should be doing is printing out your day ends, your day end reports. I was not doing it right away because I tried with the dental software. It just wasn't working. I thought I was doing something wrong, but now that I finally figured it out, they do say you should do that every single day. Now I don't see patients every day. Sometimes I see one patient, sometimes I see two patients, sometimes I see four patients. So for me, I do it at the end of the week. But you probably see more patients than I do. So do it every day. So then that way you can keep things organized, everybody. That's the key. For tax purposes, if you are a mobile dental hygienist, like I am, you should get the app QuickBooks and keep track of your transportation. Every time you go to a patient's house, what am I trying to say? You need to put down the kilometers traveled the address of that house, who you saw and why, and then the kilometers for on the way back. It's a pain in the bum, but that's how you will get that tax right off, but you have to make note of all of that. Do it right away. I used to have a spreadsheet on my computer, but I find I'm not always at my computer. So I now have it on my iPad, where it's just all right here. So even as I'm in the car, I just quickly do that so I don't have to worry about it at the end of the week because things come up, you get tired. Keep track of that. So I did mention the QuickBooks app. That has been so nice for me. So your dental software is kind of like a QuickBooks too, where it should keep track of everything, but I use QuickBooks for other things too. So anytime that I purchase dental supplies, any expenses, I put that in my QuickBooks app, and that actually keeps track of what I'm spending. When I first opened up my own practice, when I needed something, I just simply bought it. But now that it's been a year, I do have an idea of what I need and what I don't need. Some things I'm like literally ordering every single month, but I'm trying not to do that because if you order a certain amount, you get free shipping. So I'm trying to place bigger orders. It's harder on the credit card, but if you get free shipping, save like 13, sometimes $30 per transaction, you kind of want to do that, right? Keep track of those expenses. I'm hoping you're at least doing that for tax purposes because that will be a pain in the bum to have to go back later, but keep track. Like I am so organized now, where I have categories actually in my QuickBooks app, such as Amazon because I do purchase like some things on Amazon, including I just bought a side table, a portable side table for my mobile hygiene practice. I bought Daisy Chain bib clips off of Amazon because they're a lot cheaper. I bought safety glasses for my patients off of Amazon, again, a lot cheaper, but keep track of that too. So I have a category for Amazon. I use the company Maxill for a lot of my ordering. I use the website KDental for a lot of my ordering. So I keep track of things that way. So then it just kind of helps you manage your money a little bit better too. These might seem like super obvious things to you, but it took me actually a while to learn. So I hope that this helps. I'm sure I have more tips, but those are just kind of most important ones that I can think of now. Any questions, let me know. I'm so happy to help. And thank you guys so much for watching and I'll see you guys in the next one.


How did you find out about Bitcoin?  The, you know, in the news articles those little gold coins. Yes. It was one of those. And so this is back in like 2012, so Bitcoin is like $10. I'm so jealous. Oh my god, how heavy is this, Dan? There you go. You almost got it. I think it's as tall as you are. Hold on. Almost. Almost. What's up guys? Hey, what's up guys? Hey, what's up? Are you shooting some guns? Okay, wait, tell me what I need to know. I've never done this before. So, we'll take you step by step. First thing we need to do before we go in is we gotta protect our ears and our eyes. So, I first discovered, you know, Bitcoin NFTs, all that stuff on Clubhouse. And I for sure thought it was a fad. I thought possibly a scam. I saw my friends moving to Twitter Spaces and they were still going. And these are people that they wouldn't just stick around for no reason. And so I got involved and, you know, I started becoming a part of the community. And I'm like, how do I enter this space authentically without being pretentious? And my background is an interviewer. So I'm like, let me just go in. I'll be the interviewer. I'll ask the dumb questions and it'll help people who are entering the space because I'm not afraid to ask the dumb questions. You know how to hold the right hand. Yeah, I've got an AR. Perfect. Yeah, it really doesn't move all that much. I may not even put my hand on your shoulder if you don't need it. Cool. Let's hop in there. We're shooting the German MP-40. The German submachine gun from World War II. It's a vintage item. I have not seen before. I did not imagine this from a teddy bear. This is the Texas side of me. Shocked, alarmed, appalled. My normal life is in Austin here. Austin's got a pretty great standard of living. So yeah, I feel super comfortable. I feel like I've hit those goals when I was younger and wanted to go achieve. I think with money there's always more. And so that's always, I think, like a humbling process of thinking through, am I happy with what I have? And so yeah, I'm very happy with what I have. I say a very large percentage of my identity is associated with crypto. I've been in the space 10 years and so this is something that I believe is important for humanity and that's my life's mission. You can mail this to your exploit room. Anonymously, though. Yeah, exactly. Ready to go? Ready to go. You're seeing the cold, but you got distracted. Yeah, that's difficult. Oh, hey, sorry. Nice to meet you. It's got her. All right, so this is my friend from LA. She's got to get all textist out. So I took her shooting guns. We're going to go get some tacos. But we need to get her some cowboy boots and this is the place to get her cowboy hat. So what do you recommend for her? What do you think is good? Typically I'll say, let's look at your color profile. The shape of your face, your shoulder width, that helps determine the brim length, the crown shape. Also just things that generally compliment your image. Have you ever played with color? 1300. Oh, that's it? Dan can afford that. Yeah. See how much Bitcoin is that? That's 0.1 Bitcoin. No, that's 0.0. And ETH is actually dropping right now, so it's almost one ETH. It's almost one ETH, yeah. In your theory of your world, my Bitcoin world. Yeah. Which is interesting to think of it that way. It's much easier to spend one ETH than it is to spend $13.50, by the way. It's a super weird thing in our world. It's easier to spend ETH. Like an NFT, you'd go buy an NFT for $20,000. I've bought an NFT for $20,000, but if you asked me to spend $20,000 on almost anything, I'd be like, that's too much. What's the most expensive NFT you've bought? I bought a goblin for about 20,000 recently. What's the part that takes the longest?  It's like my brand name is Trovedor, Spanish for Trovedor. Singer, songwriter, storyteller. Once you had to tell a story about your life. So I ask everyone to fill out this profile looking for overarching themes of your life, significant numbers, travel stories, quote, song lyrics, and we build all that into the half of symbolism. So everything on there is essentially you. It's all intentional. I had no idea that it was like that, is that just your thing? In the world of NFTs, I love that artists can monetize their work to the extent, you know, that they can make a living off of it and even, like, get rich, rich the way they couldn't before. I know a ton of artists that are able to, like, put their kids through school now and do things they didn't even dream that they'd be able to do because of NFTs. And so that's been really cool, but also when I got into crypto, I learned a lot about financial literacy and I'm still learning. Those heads are amazing. Like, they're beautiful, like, like a statement piece, but to come and actually, like, sit down and think about, like, lyrics and themes and stuff like that. Like you say, it's like proof of work. It's like proof of work. No. We just have three children. But that's... It's my favorite food store. We really wanted to get Nicole all Texaned out. So we're doing, we did, we looked at capital hats earlier. Now we need some capital boots. Okay. Learning more about Bitcoin and understanding where we are currently helps drive that conviction long-term. So, yeah, it's through this field aligns you with some of the smartest people out there in the world and some of the dumbest. It's cool. It's interesting. Sometimes I'm a little worried about, like, things that I do or things that I say. It's scary being on that. We're on the edge of, like, glory and destruction because you can be canceled or something you say. Or you can have, like, Elon Musk between you or something. So how much is a boot like this? It depends on your base price. We go up to 2,000. And that depends on if you get fancy, if you get exotic skins. So this one is 590. Okay, cool. Alright, Nicole, which boot are you going to choose? You've got your brown ones. And you've got the black one. What's the hesitation? I like the length here. I like the design here. But it's like, I already wear so much black that maybe I should just go with the brown. The brown is nice because the brown has, like, that suede look to it, which is a little bit softer. Are you telling me I need to be softer? Is that what you're saying? You're kind of intense. You're, like, really toxic on Twitter sometimes. How? How? I'm so nice to the... Come on, come on, just relax. Well, how are you about Bitcoin? Okay, maybe I get a little bit intense too. How about we both soften? How about we both soften? I think the world's telling us that the brown is what we need. Okay, all right, let's do it. Awesome, let's get you set up. Decision made. Wow, so they look great. Thank you. It's your choice. Do you want to wear them out or do you want us to box them up? Let's box them up. Yeah, so I'm going to take care of your payment right here. Sweet. Okay, cool, but I have to ask, can we pay in Bitcoin? Sadly, no. But because you walked in and mentioned it, we'd never thought of it before, but now I'm intrigued. Okay, cool. So I'm going to give you my business card and hope that the two of you get in touch with me so I can learn more. That sounds good, but well, I guess we'll have to pay with dirty American dollars for now. Fiat. Fiat currency, no. You know, I used to think Fiat, when I first heard it, I'm like, are they talking about the car company? Oh, and it's a bad car. Did you see the Fiat Twitter account?  Yeah, I took this. Oh man, yeah, I saw that. I feel like it's very empowering to be able to think about these new structures where we don't have that centralized control. You know, that's ultimately why we're here. Yeah, and I feel like Bitcoin really is truly the only fully decentralized currency. The way I phrase it is that the other ones trade off decentralization to do more cool, fun stuff. Yeah. And that's cool too. That's cool. Because Bitcoiners could be, and this is, I think, like, this is where a lot of Bitcoiners don't question the nature of Bitcoin. What if Bitcoin has over-optimized for security or decentralization? It could be over-optimizing for that. I admit that could be a flaw in our thinking in the Bitcoin community. Or maybe them trading this off is okay. But I do think Bitcoiners are right long-term. If states attack crypto, you want to be as strong as possible or decentralize as possible. But they could be wrong. Maybe states never do attack crypto, and you could trade off a lot of decentralization. But we won't know until that happens. Yeah. I mean, where are we going to be in 5, 10 years? Who knows. Who knows.


Pregnant cat gives birth, but vets realize those were not kittens. Cats are truly amazing and never cease to surprise us. Take Musia for instance, who managed to surprise not only her owner, but a whole team of vets. She shocked everyone when she was found in her bed, nursing her babies. The favorite resident of the sadgharad Zoo in Russia was Musia the cat. She turned one year old and had been acting strange before, but this time she was pregnant and everyone was making sure Musia felt safe before giving birth. Although she waddled around the petting zoo, Musia was always around someone. Now, the staff was anxious because she disappeared. At the zoo, there were more than raccoons, geese and chicken. There were also tigers, lions, bears, monkeys and other animals that may put Musia's life in danger. They began searching for her. Musia became a resident of the zoo by mistake. She was found by zookeeper Alice when she got at work. During a cold winter morning, Alice noticed something black moving among the snow.  It was a tiny black kitty, almost frozen. Icicle stuck on her nose and barely moving, this kitty challenged the vets at the zoo that first few days. Alice took the kitty in her jacket and ran inside, looking for the vets. They did everything to keep the tiny cat alive, but only time would tell if she would make it. To everyone's surprise, the tiny kitty made it through the first night, and then as days passed, she grew stronger. The keepers kept Musia in the staff room and always came inside to check on her and cuddle the tiny ball of fur. Musia was the beloved cat of the whole staff at the zoo, and she slowly got strong to run around every day. But the staff realized she was in danger. All cats want to explore, and Musia managed to take a peek outside the staff room and look through the window. She was wild animals afar, on the other side of the window. One day, Musia slipped out when the door was opened. Alice had taken Musia out on short walks on a leash, fearing she may slip in the wrong enclosure. They've managed to do that for nearly a year. But now that she was out, everyone wondered what would happen to her. Two days of searching for Musia, Alice looked in different enclosures, hoping the cat didn't reach the crocodiles. Everyone at the zoo hoped Musia was safe, but had known she was going to be in danger. Alice had been warned that Musia may not return, but she still had hope. Sometimes, it's good to have faith. Alice continued her search and Musia was indeed back at the zoo. Eventually, Musia came back home two days later and pawed at the glass door to enter the staff room. Alice cried when she saw the beloved cat safe and sound. She even considered finding a home for the cat, but saying goodbye was difficult so Musia remained at the zoo. Soon enough, Alice would learn that Musia was not exactly the same. A few weeks after getting back at the zoo, Musia changed. She got cranky and lethargic, and it was weird. Before leaving the zoo, the cat was playful and always up to no good. Now it seemed like she was just lazy and didn't even want to go outside the room when Alice opened the door. What was happening? Musia was like a totally different cat. When she decided to go out, she just lied on the ground. Something had changed and Alice noticed it but couldn't find an explanation for this new behavior. Her sweet playful cat was broken. It was as if Musia lost interest in the outside world. Nobody could have guessed the reason why she acted like this. One day, after Alice returned to the staff room to have a hot cup of tea, she looked for Musia to cuddle her. Calling her cat, Alice realized that the room was completely empty. Musia was again missing and the weather outside was terrible. Rain started to fall heavier than usual. Then Alice hear the thunder. This time, Alice and the other keepers knew that Musia needed to be brought back inside. They took flashlights and started searching for her. Looking through every nook and cranny at the zoo, the keepers kept silent, waiting to hear a meow. They were sure that Musia was around there somewhere. Outside the zoo, there were cars and some parking spaces, so Musia couldn't have found a place to hide. She had to be at the zoo, thought Alice. Then, she heard a cry. Just past the lion enclosure, in the wood area, Alice and some of the keepers heard noises coming from a bush. A pair of eyes could be seen when Alice pointed the flashlight at the bush. There she was. Deep in that brush, Musia sat peacefully, but she wasn't all alone. Something crawled on her chest. Alice took a better look and couldn't believe her eyes. Musia had always been fluffy so nobody noticed that the cat was actually pregnant. With her, there were four newborn kittens meowing. But here's what shocked the keepers. However, aside from Musia stunning everyone when they saw her kittens, what really amazed everyone was that something else crawled up her chest. Those were baby hedgehogs. Alice and the keepers had no idea what to do next, but they knew they couldn't leave them there. One of the keepers went back to get a box and a blanket to get Musia and her furry and spiky babies to safety. One by one, Alice placed them in the box and headed to the vet room. Now everyone had more questions than before starting to look for the cat. Alice put the box of babies and brought Musia to the vet, and when he looked at the box, he frowned a little and then started laughing. I've never seen anything like this, he said and started looking at Musia and her babies. He decided to separate the kittens from the hedgehogs and left the room to talk to Alice. But once Musia was left alone with the two boxes, she decided to get her kittens and move them into the box with the hedgehog babies. She sat with them all and purred, letting all the babies suckle and cuddle with her for heat. Alice came back and saw the group once again huddled together, and that's when she realized it.  Alice was amazed but worried that the kittens may not be safe around the pricks of the baby hedgehogs. She separated them again and tried bottle feed the hedgehogs. However, they refused and Alice realized she had to return them to Musia. Although Alice believed the baby hedgehogs were not exactly safe for Musia and her kittens, the cat wanted to nurse and take care of them all. Later, Alice found out the origin of the hedgehogs. It seems their mom may have gotten in an accident at the zoo. She did recall that tragic lawnmower incident. The baby hedgehogs had been alone for a few days before Musia found them. They must have been starving before she claimed them as her own. Nobody knew whether she had rescued them before or after she gave birth to her kittens. So what happened to this odd cat family? Not even once had Musia been stung by her baby hedgehogs. She raised them like her own and Alice helped her as much as she could. The staff helped her set up an enclosure for the new family just outside the staff room, and when Musia's story went online, it went viral. Sharing all these cute photos of Musia nursing her prickly babies had stunned plenty of people. Cat lovers around the world were praising Musia and dog lovers agreed that she was a very gentle mom. Without knowing, Misa has showed the same kindness Alice did when she saved her from the freezing weather a year earlier. Now, the baby hedgehogs are adults and Musia guards them every day, showing up at their enclosure and making sure they're all right. This has been quite a story. What would you have done if you had discovered your cat decided to adopt eight hedgehogs?


Good afternoon to everyone. I am Divya Thadi a student of third year Tripoli in BVRIT Hyderabad, India So today I'm going to present a talk on real-time monitoring system using wireless sensor network for mine safety So as we all know in mines basically the workers are prone to lots of toxic gases as in when they are when they are mining activities that go on that is Maybe blasting or something at that point of time the many gases that is some some of them are very toxic that come out Due to which the minors minus health are in jeopardy So basically my real-time monitoring system tracks the amount of I mean the parameters that monitor the gases that is the toxic gases etc and displays them onto the screen so The contents of the talk the problem statement problem analysis problem solution the technical solution technical implementation prototype zigbee configuration Final data output prototype snippet further development Okay, what's the problem statement? So we have to prevent the unsafe incidents that are occurring in mines basically So we have to prevent the fire explosion and accidents We have to prevent in unsafe Accidents that are causing health issues to the workers Thus protect mine safe my mine workers from hazards thereby also reduce losses of property productivity and profits Protect destruction of natural resources and environment The challenges Sorry Okay, so we have to create a real-time monitoring system of Which monitors the safety parameters like the gases The the toxic gases temperature and humidity Okay, so the challenges that are being faced while doing this are is collection of data Transmitting the data acquiring the data from the underground mines analysis of the data generate relevant alerts So the problem analysis is divided into two parts That is one is the fire accidents and one is the gases that are being produced So the fire accidents have the source and impact. So the sources are gases released you do during explosions and That and gas is released in coal beds. So the impacts of these are injuries or life loss and Also loss of property and productivity So the incidents of explosion and fire depend on the flammability of gases and is high in methane and carbon monoxide So and the generation of harmful gases Sources and impacts so the blasting and explosion gases released from coal beds Spontaneous combustion Accidental fires so the impact of these sources are health that is mainly on the health impact. So Asthma bronchitis headache fatigue and sometimes causes death So these two gases are considered for the prototype that is the methane and the carbon monoxide as of now So they're more harmful gases than these two. So the harm the health impact depends on the exposure time and toxicity levels We need a system to remotely monitor the gas the gases and fire exposure in real time So the problem solution is We need a monitoring system to monitor the fire accident and harmful gases and to monitor this we need a Temperature we and we need to monitor the temperature humidity methane and carbon monoxide So to monitor these parameters We need some sensors and the sensors I have used is DTH 11 sensor MQ 4 sensor MQ 7 sensor so After monitoring, I mean after getting the values from the sensor we need to you know Basically send the information to the computer so that someone can actually monitor the date of the parameters and also when the Parameters exceed the threshold value. We need a buzzer to basically give up an alarm that this is exceeded the threshold value So the technical solution is we are going to have two Two two units one is the sensor unit and another is the monitoring unit and in the sensor unit We have the sensors first that is methane carbon monoxide temperature and humidity and These sensors would be connected to the microcontroller and the microcontroller basically acquires sensors data Processes the data controls the buzzer LED and the Zigbee transmits the data through the Zigbee and This micro data from the microcontroller is being transmitted to the Zigbee so actually I've used the Zigbee technology because its range is really very high and Basically Zigbee has this set data wherein it transfers One 250 kilo bits of data per second So which is actually suitable for sensor technology whenever we use a sensor input or any input device This Zigbee technology comes into very handy So I have used two Zigbee I have configured one Zigbee as a transmitter and another Zigbee as a receiver So this Zigbee transmitter basically basically connects collects the data from the microcontroller and then Transmits the data to the Zigbee receiver that is in the monitoring unit So the Zigbee receiver here collects the data from the Zigbee transmitter and Further transmits the data to the Zigbee monitor and And near the Zigbee monitor we have acquired the data from the Zigbee receiver and displays that data So the technical implementation of The sensor unit and monitoring unit. This is basically a methane sensor Carbon monoxide sensor temperature and humidity sensor So these three sensors are connected to the Arduino, you know, which is the microcontroller and In turn connect and an Arduino, you know is connected to a buzzer and an LED display and The Arduino, you know has to be interfaced with with the Zigbee and for which we will be needing an interface board So here we've used a Zigbee interface board and yes, this is a Zigbee trans transmitter and This is the Zigbee receiver and this is a Zigbee receiver board Which should be connected to the monitor display. So I would like to Tell clearly the flow. So basically the sensors will be sent sensing the Parameter, I mean sensing the gases and all From which the information will be passing on to the microcontroller The micro if the threshold values of the gases, etc. Will be exceeding the limits it will be sending signals to the buzzer then the buzzer will buzz and And simultaneously this these values will be displayed on the LCD and later Okay, so this is the sensor unit and the monitoring unit as you can see This is the LCD Where in the values of the temperature? Carbon monoxide and all are displayed. This is the buzzer and These are the sensors. This is a Zigbee transmitter and this is the microcontroller This is a sensor part and this is the monitoring unit and the monitoring unit consists of the interface board and the Zigbee module Moving on to the next slide how to configure Zigbee So we have an Opens of software called XCTU software wherein we can configure the Zigbee So we have to conflict to configure the Zigbee one as in coordinator another as a router So Here we have to set the same pan address for the Zigbee and the For the Zigbee transmitter and the Zigbee receiver and we have to you know, basically make some changes in the Configuration such that one works as a transmitter another works as a receiver and set the remaining values to the Ziddi default So this is the final data output. So as you can see this is the transmitter Zigbee This is a transmitter the Zigbee and this is the receiver Zigbee. So I have got the temperature sensor methane sensor and the carbon monoxide sensor values on to the Zigbee receiver console. This is the final data output So this is the prototype snippet So it is hard to test the methane and carbon monoxide values in in a home environment Basically, I've I've set this up at home So it is basically hard to test those so in order to show the working prototype what I have done is Reduce the threshold values. I have ready. Okay. I'll just show the video Okay, as you can see the temperature value is 31 The methane value is 192. So likewise what I have done is I have reduced the value of the temperature in the code So I'm dumping the code It's compiling It's uploading the code to the microcontroller and This is the buzzer. So by reducing the threshold value. I have Basically found a way to test this test whether these sensors are working or not So likewise, I've changed all the other parameters values I have reduced the parameter threshold values and I've checked whether the sensors are working or not I have test tested all the four sensors Sorry, sorry So this is the working prototype So the further developments add more sensors for detecting other gases like carbon dioxide oxygen and hydrogen sulfide Perform testing of sensors in real lab environment using fire temperature methane carbon monoxide, etc Design and develop the casing for the device Program the monitoring unit to process the data acquired Perform analysis and generate appropriate message alerts and warnings Establish a two-way Zigbee communication and develop Zigbee network model and test this product on site Thank you. Any questions? Okay, do I have to tell individually so the So actually I'm gonna set up a network. This is basically only a device right in later in the later time I'm gonna make it a network. So I cannot write. Okay, I'll just tell you the details of this Approximately it's gonna cost thousand rupees only the the monitoring unit and Then the receiving unit the bigger one that I showed this side that's gonna cost about two thousand Overall, this this whole thing might cost approximately to three thousand Yeah The the sensors can they be used for monitoring? Yeah, pollution so in underground mines you want to test the pollution Yeah, so there'd be there are other other sensors which can be used to monitor pollution So I think it'll be better to use that that Yes, I have calibrated So in later time what I am planning to do is give the Threshold value so see now I have given the threshold values as 30 As you saw in the video so later I'm planning to give this this set of thing to the owners of the mines wherein they can set because that mining temperatures differ might differ Right, so I'm planning to make a small website kind of a thing wherein they can actually put this threshold values they can actually stipulate those values and they can Give that threshold value so that It connects if it exceeds that value they can monitor Yeah, so the the sensor values goes to the Zigbee every second So actually right now if I have the Zigbee I can I can show you every second that is coming the The data ever goes every second so I could have showed you that but right now I'm not having the Zigbee module with me So I just showed you this right so So what one does that one one? Manually yeah Swing yeah So maybe I I'm actually planning to write a code for that also To actually if a person is sitting right in front of the monitor in case that Threshold value exceeds I would write a code where it buzzes there also So it'll be easy for him to notify to get notified if there's a swing in the gasses sign or sensor values So I didn't know basically if the if it dies we have to replace one we have no other option Yeah, there's no like that so I was gonna use it to control Robots in the fact in the French factory, and then I realized if this thing dies of me my friend's Investment Yeah, so Noting this point. We have used the Zigbee technology wherein it's very easy to replace the end device So it is very easy. So we just have to replace the Arduino not the whole setup It is very easy this way. So that's the reason I chose the Zigbee Zigbee technology in this case There are plenty of fake Yeah, exactly the same. Yeah Okay The Arduino has a map of Italy printed on it the original one is in high-res the fake one Yeah, I'm not as good. Yeah Yeah, so we have to we have to be very keen while selecting the Arduino. That's all we can do We have to be vigilant while selecting one Thank you. Any more questions No Yeah Pardon Zigbee Yeah Yeah, I'm gonna try meshing I mean use the mesh network in the in the latest stages because this is only the prototype of the devices So later I'm going to create more such devices and create a mesh network So that information from miles can be trying I mean from different from distant places can be You know, basically an information can be retrieved from distant places also Thank you. Yeah I Didn't get you if we can actually increase the sensitivity So in case we need we need to we need to catch up very small amount of gas also We need to you know, change the sensitivity values in the court so that even if this slide change We can actually catch the gas values Any more questions? Yeah, thank you


Hi everyone, this is Jason here from Nathaniel. This is a rather unique exercise, at least for me, because it doesn't have too much of theory. There's no real chords going on. I think it's very easy to actually execute. And what you heard in the intro performance was it just sounds like anything a pianist would do in like a movie, you know, or in any kind of background score or theme soundtrack for a film. It's sort of like what a piano player will end up doing. Maybe this is a song in a movie, I don't know, perhaps, right? So it's a very popular technique if you want to do like a thematic stuff or scores or those sort of piano arrangements. It's also great when you're doing solo piano work, like if it's just solo piano, no singers and all of those other people, it's just you on the keyboard. So you do... You can kind of play that and it's a song, so to speak. So I've developed this exercise in a very easy to understand way. I'm just going to give you three sets of three notes, okay? For the need to kind of explore different scales and different finger positions, I'm going to give you three note combinations. So the first one will be on C sharp, which I'm going to demonstrate on so that'll be C sharp, D sharp, E. Got those three notes and generally you want to play those three notes with the middle fingers, the index on C sharp, the middle finger on D sharp, the ring finger on E. That's going to be your consistent or pivots which will not move throughout the exercise, okay? Then the other set of three notes will be C, D, E flat, okay? Again, you can play it with these three fingers and lastly we are on D, E, F. That's the next set of three. So we have C sharp, D sharp, E, then C, D, E flat and finally, D, E, F. So I may be explaining it on either of these three notes and I may be explaining it on either of these pivots and it'll be written down so you can check it out and learn accordingly, right? So now we are going to add one more note to this set which is going to be a floating note and thereby creating the music and then we explore it in different time signatures. That's our goal. We'll do it over a six feel. We'll do it over a four by four feel. Then we'll do a ton of variations. Then we will ask a question to what the left hand should be doing amidst all this depending on your knowledge of the scale, etc. With these three notes you can perhaps already kind of figure out that okay, it's part of some scale. Like C sharp, D sharp, E could be part of the C sharp minor family that one or C, D, E flat could be part of the C minor family which is well, the D, E, F could be part of the the D minor family either the natural minor or the harmonic minor usually you can always interchange those two scales whether you want to consider it as the natural with the flat seven or the harmonic minor with the normal major seventh or the raised seventh but the D, E, F becomes the first three notes or the sare ga of the scale sare garesha sare garesha or sare garesha so those are the three notes which are never going to change that's what makes it very kind of thematic when you have these clusters even playing it together like that is quite interesting right makes an interesting vibe or of course that's not what we are going to do ok so let's get cracking and all that's going to happen now is we figure out how to float notes and when you float the notes it's pretty much going to be within the scale so it's good to know your scale and write it down and obviously the notes are provided which you can check out as usual on our Patreon page where you get all the stuff written down for you so you could download a pdf and watch this lesson before we get started it will be great if you haven't already please hit that bell for notifications a lot of you have subscribed which is great thanks a lot if you haven't please consider subscribing and also turn on that bell let's start so if I have to take let's just start with D E F or no let's start with the tough one not really tough actually I find this the easiest so we'll just begin with C sharp D sharp E now the bass in this hand you can perhaps consider G sharp which is part of the C sharp minor I don't want to go too low because then your hand will get a bit too stretchy or tensed up let's not do all that so the two ways of playing this would be go in 4s groups of 4 so you can even say 16 note counting your terminology is like 1 E and a 2 E and a 3 E and a 4 so you've got yourself an arpeggio so the arpeggio is built out of the unique note in this case G sharp and then the consistent notes which is C sharp D sharp E let's get this going so this is style number one or pattern number one arpeggio now you could do something very easy with the same arpeggio and make it more swaying give it a more swaying feel or a 6 by 8 feel by doing this what did I do here I just went up and came back down so that will be 1 2 3 4 5 6 so if you add the going down you'll get a 6 8 arpeggio flavor so style number one or rather this was style number 2 and style one was that where you just do 16s 1 E and a 4 1 and 2 coming back to 6 8 2 strong beats right 1 2 3 4 5 6 1 now you don't have to just stick well this sounds quite awesome to my ear but you could you need not just stick with this G sharp you can kind of float it around as long as you're in the key or even outside the key may sound good because right now you haven't committed to anything I've just told you 3 notes and a G sharp to support it now let's support it with some other note maybe A I'm doing 6 8 A A sounds quite nice yes so toggle G sharp A I don't want to go too much below because it may hurt my hand so keep your hand relaxed when you play A let's see what A sharp has to offer or B flat now that's outside the key of C sharp minors right why not sounds very James Bond like some left hand you always have those 2 flavours so you could do even a B could work you could just support it with some kind of a root in this case C sharp seems to work great you see the float in the bottom C what G is also quite interesting I have no idea which scale I'm in it doesn't matter you just move your thumb float the thumb and just see what you like and then piece a pattern together so A G sharp maybe B B flat or A sharp A that's my progression and that's how intense it sounds with literally no bass movement in the left hand that's like zero harmony that'll push a bass player to sleep isn't it so you go what if you change the bass or what if the bassist or your left hand starts waking up you know A there F sharp and maybe you could do G coupled with an E flat I always like to think of the left hand as being forming a third with the right hand somehow that way you get some intense harmony right some of them may not work you know actually works or stay on that now I'm just exploring but I hope you get the idea that the left hand if you just even if you stay on C sharp which is the root it sounds quite intense maybe you could build your theme with C sharp don't change that make the theme intense with your floating thumb you're creating some tension which you release at the next section with the bass movement changing simple bass just hold it not really thinking of much there's no chord theory there are no chords also going on here if you think about it where was there a chord you may extrapolate a chord from this information but we were not thinking oh C sharp minor A major like that we were just saying three pivoted notes a floater and then floating bass if you so choose to do so now let's just so what do we have so far we have a pack of three which won't change we have a floating thumb and we have well the thumb can float around and we create an arpeggio sequence either with force or with sixes which I tend to like a bit more sounds a bit more lazier laid back we have those two patterns so we are going to keep those same two patterns throughout let's just see how this sounds on the next grouping so let's see what happens with the next grouping what did I tell you earlier C D E flat so start with a G A flat B flat and so on you play with it you're on a new scale you think like you're perhaps on C minor which it is I think you could even keep this consistent and move around your bass very similar to that Led Zeppelin song or the Beatles song which you all know this is even without changing the floating thumb you know you're floating the bass so you decide you want to float both this and the left hand feel free you want to float only the left hand feel free keep the left hand static float explore the thumb feel free but make sure you're in the arpeggio set or in the arpeggio motion which is that or ok let's just take the next set of three notes which is D E F the trio of three this will not change let's see what happens fairly similar right so what can we do to kind of spice this up further well we just use a few logical movements or logical progressions from where we are now I think this already sounded quite nice but you can think of simple simple systems where instead of going what happened here the movement of the arpeggio is just going up or down if you're doing 6-8 what if it goes down or then down and up on the other one it's completely different vibe well similar vibe but different theme or you could play this higher actually sounds familiar even to me for some reason yeah I'm sure you'll find that this is very common if you watch a lot of movies which I probably need to start doing more off now or you do the going up version going down again you just take the information and kind of bring it down ok and the pedal is again something I'm not able to show you at the moment but I'm trying to use the pedal to give that resonance between these neighboring notes apart from the pedal holding the notes down apart from the the felts hitting the string and kind of keeping them to vibrate they are also in resonance with each other so because of that it creates a very interesting sound a very dreamy sound versus without the pedal so with the pedal gives you additional harmonic content which is provided because the resonance created between those notes and the hammer is hitting on a real piano ok so either you go up or you go down float the thumb as always now what else can you do you always ask yourself what you are doing now and then try to figure out what is the opposite of what you are doing now that can be a very good tip as a piano player so you are floating the thumb what is the thumb next what can we do remove the bottom remove the bottom most note and start floating it from the top end there you are probably going to use a lot more of your pinky and the ring finger perhaps so maybe let me demonstrate this with a C minor system may be easy for you to understand so now the pinky is floating and maybe I could bring in the ring as well so basically the top note earlier the bottom note was floating with the same pivots now the top note is floating with the same pivot so then go descending up or down and now I am floating the top note and now your next section could be with the bottom float with a whole new varieties of note options next section go higher and float if you piece them together what I am encouraging you to do as a learner would be to build more and more sections of music with this information don't just say ok I will practice it and make one part don't be happy with that try to expand it think like you are scoring a piano composition for an entire maybe an entire movie scene like the scene will take some time it will probably take I guess 5 minutes at the minimum so figure out a way to expand this or extend this for a good duration of time be it 5 minutes or at least 2 or 3 minutes of data you should be able to produce and whenever you are saturated with ideas think of the simplest things in music which are volume and duration so if you want to think about it that way maybe start soft and play high you know or now go lower and play in a more intense way same music a different perspective or you can think of short and long this is lagato versus staccato so whenever you kind of feel a bit saturated with ideas make it staccato versus lagato lagato staccato or play higher and softer or play lower and I don't know why I am going low and loud maybe I should probably do low and soft maybe my brain is not really wired that way at the moment so maybe that's for you to do so finally in conclusion some more food for thought or a bonus tip for you guys would be now if you think about it logically you have the pivots which is the index finger, middle finger ring finger when you floated the thumb the pinky was kind of sleeping it was not doing much what if you float both the notes that will be another question you could ask and then you have all your five fingers doing or serving a specific role on the piano so if you thought there is a thing called hand independence on the piano there is also something called finger independence on the piano where each finger has its own mission for the sound or for the music the floaters are going to be this side and that side and the pivots or the anchors are going to be here and then you can do a bigger arpeggio using both the floating notes the thumb floater and the pinky floater so you go so you are building a bigger arpeggio it seems to be in a eight feel right eight set of notes now the beauty of this is you don't have to float the pinky to the same note you are floating the thumb that will also sound nice or you can kind of choose your own note here like F and you blue G here and then we have the left hand which is like free to roam about either inside the scale or wherever else it needs to go it completely depends on the theme you are trying to build the story you are trying to communicate to your audience so basically what you end up doing will define the objective of what you are trying to tell your audience as a storyteller right so ultimately this is your medium of expression these are the words and the sentences and the tools you are using for the language of communication so you have to think about it in that sense you have to think if I do this maybe it will feel like this sort of a vibe or this sort of a theme maybe if I do something else it will sound very romantic if I do something else it will sound like a very very dark theme a very scary theme or something like that so you have to kind of explore I guess you know along with our notes in Patreon I have also notated a simple performance which maybe you could end up playing by the end of this entire saga of things which I have told you maybe you could just start with something very very fixed and focused I am also going to record that melody at the end of the lesson so you can practice just that melody you know at least to start off with and then you can explore on your own or you don't have to do the melody it's up to you really

So our next presentation is by Millie Chapman of the University of California, Berkeley, talking to the role of AI in post 2020 biodiversity targets and effective management something very close to the work we're doing here at. Hi, my name is Millie Chapman and I'm a PhD candidate at UC Berkeley and the Department of Environmental Science Policy and Management. Today I'll be presenting about the use of AI in conservation decision making. I'll highlight some of our recent work showing that reinforcement learning holds promise to improve our capacity to effectively make decisions in the wake of global environmental changes. I'll also present some of our work on the ethical issues and power considerations that are critical to equitable and effective application of algorithms to conservation decision making. While human impacts on ecosystems rapidly accelerate our techniques for observing those impacts are increasingly outpacing our capacity to respond to them. Advances in artificial intelligence have largely been applied in conservation science to more precisely document the impacts of environmental change through improved and automated data classification workflows. But solutions to the global biodiversity crisis will rely on more than our capacity to more precisely estimate animal populations or dynamics. We must also improve our capacity to translate imperfect information about environmental systems into effective management decisions. So throughout this presentation, I'm really going to focus on the work that our group is doing to explore applications of algorithms and decision making and decision support processes. But can AI really help us make better conservation decisions? That question is inherently both technical and social, and the two parts of this issue are interdependent. The few projects I'm going to briefly present on today are addressing this larger question and the result of collaborations between environmental scientists, computer scientists, sociologists, and ethicists. I'm going to start today with some of the technical work happening in our group, which is largely exploring deep reinforcement learning as a method for addressing environmental issues. Quickly before I get started, I just want to explain what reinforcement learning is. It's really just an area of machine learning concerned with how intelligent agents ought to interact with an environment in order to maximize some notion of cumulative rewards. In the interest of time, I'll spare you all the details here, but if you're interested in learning more, I'd encourage you to look at our lab's recent preprint on these ideas. But in the most basic terms, reinforcement learning consists of an environment, which might be a fish dock or a wildfire or any number of environmental problems. And then there's an agent. So the agent takes an action in the environment. So in the case of fisheries, the agent might choose a harvest quota. And then the agent receives an observation of the environmental response to its action and a reward. So over thousands or millions of iterations, the agent learns how to effectively interact with the environment to maximize its rewards. So some of the advantages of using reinforcement learning over traditional optimization or decision theoretic approaches include flexibility and problem formulation. The environment can be really indefinitely complex and have large state spaces. Now the agent might have trouble in a particularly complex environment. But there's no true constraints on the way in the same way that there is with traditional approaches to control problems. Additionally, reinforcement learning can leverage existing ecological models and simulations for agents to interact with. In this preprint, we show that reinforcement learning holds promise for informing decisions for a number of environmental crises using primarily simple examples. So kind of what next. We're continuing to work to develop more complex case studies, for example, can reinforcement learning help us design dynamic marine reserves in a changing climate. And second, we're continuing to work to develop methods and theory around this approach. So what conservation questions are most suitable for reinforcement learning and what reinforcement learning algorithms are most effective at solving different conservation problems. So let's go back to the second main part of effectively leveraging AI and decision making processes, which is that these are not just technical questions about algorithm design. But they're also social and ethical questions for whom are these algorithms really creating better decisions. In this paper, we explored these broad questions in the context of algorithmic recommendations high seas conservation. Among other points we show that because algorithmic approaches at a global scale, largely consider the costs and benefits of conservation action to only a subset of human actors. Their applications can stand to reinforce power asymmetries due to do partially to data disparities. For example, sea bed mining and sea bed mining is largely done by industrial countries. So if we're trying to maximize biodiversity protection on the high seas while minimizing the impact on some sort of economic profit, we are largely considering large industries and largely ignoring coastal communities. Moreover, algorithms used in decision making processes have the potential to shift power dynamics along multiple axes. Maybe most obviously algorithms can shift who pays the cost for conservation and who receives the benefits. But algorithmic approaches to conservation decision making can also shift who decides what questions we ask and how we frame those questions. So is there an equitable path forward, and can we harness these technologies in a way that benefit more than just the powerful few that are designing and implementing them. This question continues to be an active part of our research, but in our, in a recent paper, where we're looking specifically at high seas conservation we argue that algorithms can be a part of an equitable decision making process. The interventions are taken throughout each stage of the prioritization process from procedural justice in the funding and team assembly for a project to the integration of social science data and methods in algorithm to distribution equity assessments of algorithmic solutions to ensure that optimal solutions are also equitable solutions. And with that, I'd like to acknowledge and give a huge thanks to the team who led a lot of the work I presented today, and to the many other collaborators who made this work possible. I'd also like to thank our funders for their support. And thank you for listening and please not hesitate to reach out with any questions. Thank you very much Millie thanks for sharing your story. In FAO, we do have a vision for more productive and more sustainable fisheries and agriculture, especially from the fisheries and agriculture division section of the agriculture outlook. But I think more and more people are recognizing that the word equity or equitable needs to be part of those types of visions because we've seen too many problems where we're trying to deliver outcomes.  Is it maybe maybe I will just, when you started, did you have any surprises on what you found when you started to really do the research on it or did anything come up again and again, which just showed you that that's so important. Thank you. Yeah, I think that's a really interesting question and I think it's specifically an interesting question when we start to think about the use of these algorithms on the global scale. A lot of the data we have at a global scale, particularly on human dimensions is incredibly bias. It's very biased towards large industry, largely because that's where we have sensing technologies on vessels or whatever else it is. And it's largely not in human dimensions of coastal communities or other communities that might be underrepresented on a negotiation table on a global scale. And so I think it's really interesting to start to think a little bit more about how we start to mitigate some of those data disparities that exist in human dimensions data. And I think that there are also data disparities in ecological or environmental data. Without a doubt, we have more data in parts of the world than other parts of the world. But I think it's, I've found kind of through some of the research we've been doing over the last couple of years that that's particularly striking when we're thinking about human dimensions. Thank you, Mili. Matt, can I turn to you? Yeah, fantastic presentation. Really interesting and very important to explore this. Can you tell me more detail about how ecological simulations can be integrated with reinforcement learning methods and other resources for making this possible? Yeah, that's a great question. And thanks again for having me here today. This is a really cool form. Yeah, so there are a lot of cool resources in terms of like applying reinforcement learning to different environments, which I kind of presented in that one slide about some of the technical work that our lab is doing. And the preprint that I referenced has some great resources of how you develop environments to test different reinforcement learning algorithms on. And yeah, there's a whole kind of project being run largely by computer scientists for testing different reinforcement algorithms. It's called AI Gym. And you can develop our environments of your own. And so we've been developing environments that kind of mirror environmental problems that are hard to solve with traditional optimization approaches. And yeah, kind of seeing which reinforcement learning algorithms are effective in those different environments. But yeah, I guess I would point people towards that preprint and or kind of AI Gym and some of the resources that exists there. And do you integrate any sort of behavioral change psychology into your work as well? Yeah, I think that's a really interesting question. So a lot of this reinforcement learning work is more like how do we best like control a system or how do we like best make decisions about a system and less kind of about understanding the dynamics of a social environmental system that might be experiencing what policy changes and behavioral changes. But I think that's a really interesting point that you raised that a lot of these methods are also interesting for starting to understand the dynamics of human decision in a complex environmental system. So if you have an agent interacting dynamically with a system, you could imagine kind of treating that agent and kind of exploring how behavioral changes might influence the trajectory of an environmental system.
