Welcome. I'm your host Sharon Thomas Yarbrough. Sister Power Guest's role in the community is helping the next generation understand money management. Our topic for this segment, Next Generation Financial Learning. Get Real Financial Reality. Today, Jeannie Yukitomo, OYE, USA Federal Credit Union, Senior Relationship Officer, and Kathy Morris, Program Director for Financial Reality Foundation, is here with useful tips and effective solutions to students to better manage your finances so you can reach your goals faster. The Get Real Financial Reality Fair is a fun, hands-on way for students and young adults to learn about managing decisions about everyday expenses and provide financial advice to help them keep a budget. To learn more ways for the next generation to reach their financial goals, meet Sister Power VIP Guest, Jeannie and Kathy Morris. Hello. Hi there, Loha. Loha, welcome. Loha. Welcome to Sister Power. Thank you for having us. It's our pleasure. Oh, thank you. I'm excited for Hawaii, USA. We have a celebration today in the newspaper and we have a clip here of the advertiser that is Happy International Credit Union Day. Tell me a little bit about this picture. We were doing an event in our IAEA branch and this is our team and we decided to do Have You Saved for a Rainy Day? So we had raindrops, we had all the staff and galoshes. We just kind of all came together as a team to get that message out. Have these folks saved when the hurricane came? Have you saved for a rainy day? Oh, I love that. All right, so Happy International Credit Union Day. So let's get started. Let's get started and let's talk about money management basics. And what I'm so excited about this is I think that we start late talking about money management. And what ages do you start when you're talking about the financial learning? What ages do you start? Is there an age limit? None at all. I'll give you an example. In our Kapolei area we have a school island Pacific Academy. They have a teacher that's very proactive. She decided it was going to be great to have her fourth grade class have a in-house student-run credit union. So we go there to mentor them every three weeks, talk to them about savings, how to open an account. One of them is an entrepreneur already in the fourth grade. And the fourth grade. Yes, Mr. Jobs. No, just kidding. The next Mr. Jobs. The next one, definitely. So fourth graders, it's not too early to learn to have that concept of where a dollar goes and how your mom and dad put it into their ATM account. It's empowering. It really is. Kathy, we've known each other for a while and did not know about each other. That's correct. But we've seen each other coming and going. Tell me a little bit about what you do. What I do is we go into schools. We have, I belong to the Financial Reality Foundation and we do what's called Get Real Financial Reality Fairs. And what that is, is that we go into schools, we target high schools, particularly seniors because those are the ones that are right on the cusp. They're either going to go into the workforce or they're going to go right into college. And so with that, we partner with credit unions. We bring the fare into the schools. So a little bit about the fare. We have like over a hundred and twenty-four jobs that they can choose from. So hopefully they pick something that they're thinking about in college or either in the workforce and then they receive a budget sheet and that budget sheet is a future life scenario. And so that future life scenario, they could be married, they could be married with kids or they could be single or single with kids. Once they pick their future life scenario, they get a two-sided budget sheet which has the amount of money that they make after taxes. Then it's time for them to go shopping. They buy their house, they buy their car, cell phone. Everything we do on a regular basis, monthly budget, they will do during this two-and-a-half hour period. And so the schools allow us to come in. It's free to the schools. The credit unions sponsor us and bring us into the schools. And with that, we unveil this project. The kids love it. They begin to think, I always ask them, how many of you all think you can budget? How many of you all think you can spend your parents' money better than they can? And always I have a couple of folks that will just be bold about it and say, I can. I said, okay, we're going to see you at the end. Wow, you said something about home ownership. And Jeannie, when I asked you about your responsibilities, I loved your answer. You said I have the best job in the world. Best job ever. The best job. Tell us a little bit about your job. My job is amazing because I believe my title as Relationship Officer is extremely broad.  So for example, say that you're on the big island in our Hilo office and you have ground beef. And she's over there and she's got tomatoes. And I've got the lettuce. I'm going to bring everybody together and we're going to have a heck of a hamburger. Okay? Okay. So what I enjoy about my job is I can teach people how to budget, how to save. And then in this pattern, in 18 months or so, they come back to us and I get a card in the mail. And it says, welcome to our housewarming. Please be our guest. And to know I played as a job, a little role, and them not being homeless, having a roof over their head. It's just, I cry.  But it's just amazing to see how we help people and how we can change lives just all together as a community. I'm paid for this. Well, high five on that. You're okay. Good for you. But when you say you're a little job, living here in Hawaii, and we know how expensive the homes are here. So when you are putting these people together, that's amazing for people to be able to afford to live here in paradise. I call Honolulu the bus stop to heaven. And so you are making it possible for them to have a home. So how did the two of you hook up and how long have you been partners? Well, I've been in the credit union industry for quite a while. My previous vocation, I worked at the Hawaii Credit Union League, which is the trade association on behalf of all the credit unions. And through that partnership, I got a chance to meet with many of the credit unions. And she and I formed an unbreakable bond. And financial literacy and financial education fueled that bond of ours. And so wherever she was able to go, and wherever I was able to go to teach financial education, because that is my passion, I just truly believe that we've got to empower the next generation. And it's through the credit union's efforts. It's through our program efforts. And we're hoping that this program then transitions over into the parents. So the parents then will have that conversation with the kids when they bring their budget sheet home. You know, by saying, hey, is this really real? And it is. Yeah. I wish we had that when we were coming up. We said the same thing. It's so needed because who knows if Social Security is going to be around. Absolutely. And so this is vital, the information. Now, how do you choose the schools? Basically, the schools choose us. Oh, how do they know about you? Well, when we first started in 2015, our first school was Waipahu High School. And from there, word of mouth travels. And they began to reach out to me and say, can we do it at our school? So we do public schools, private schools. We're looking at home schools, universities. But through word of mouth, they would call and say, well, can you bring the program to our school? And of course, my answer is absolutely. So my next thing is to reach out to the credit unions. Hawaii USA Federal Credit Union is one of our largest sponsors along with other credit unions here. And then they decide to host. And when they host, they go into the schools along with my program. And we just continue on. And we have gained much success. And we have reached over, I want to say, 1,600 seniors the last school year. The last school year. So you started in what year? We started in 2015 here in Hawaii. Oh, my goodness. Now, our program originated in Alaska. But in 2015, we started in Hawaii. And we've been growing like gangbusters. And we have a number of schools that have been honoring us and allowing us to come in with their program. And it's been fantastic. I mean, the students, the way that the students respond is priceless. But getting in the after is what she's leaving out this afternoon. OK, I want to hear it. OK. So these kids are walking in. And for example, I'll use the high school Roosevelt. OK. So we're there. And it's right before they're graduating. Kids are on their phone. They're like, what am I going to do? OK, it's something for two hours. And then she'll make a speech and say, OK, now. It's time to get real. So we're pretending you are 24 years of age. And now you have a career. And they're like, two hours.  And when they're now looking at this and they realize, wait, I have a baby. I have a baby. Oh, yes. That's fun. And I have a job. This is how much I earn. I'm loaded. And then she's sending them off to all these different table representatives.  You need that four bedroom, four baths, swimming pool, in Hawaii, Kai, buy that house. Or that BMW. They buy that car. They buy that house. And then they come to me at the end. They're like, oh, I'm only negative $5,000 every month. We're like, well, how are you going to live? You're now homeless. Wait, what? Well, they told me I needed this house. Well, everybody will tell you things. Do you have to listen and budget? We're teaching you to budget. Then all of a sudden at our end, they're extremely nervous, like, wait, get my calculator. What did she say? Don't talk to me. They're very changed in this matter of time. And we love it, just watching that 180 and we're sitting back just giggling, waiting for them to come. And there's so many epiphanies that happens with these kids because they begin to realize how much their parents have to do every month. And we include everything. We include credit score. They learn about how their credit score can fluctuate. They understand that credit score equals buying power.  So tell us about the yellow balls. OK, so the yellow balls are, now some of us may remember this and some of us may not. But you remember the eight balls you used to tell your fortune? Well, I think I remember that. Well, we have turned these into globes of reality. And so everyone starts out, all of the students start out with a credit score of 700. So then there are four tables where we check your credit score. That's your home table. When you buy a home, your credit score is checked. When you buy a cell phone, your credit score is checked. When you buy an automobile, your credit score is checked. And should you decide you need a loan, you can go to the loan table. And guess what? Your credit score is checked. So every time we turn these balls upside down and there are numbers on them. Plus or minus 10, 20, or 30. So their score goes up and down throughout the fair. And they begin to understand how much they pay is associated with that credit score. So this is the worksheet right here that the students start off with. Correct. And tell me about this worksheet here. I think there's something here. I'm just going to move this over a little bit so we can see the worksheet that the students start with. Tell us a little bit about that. So the first thing we do is that we gather them all up. And then we tell them you're going to pick a vocation that you're interested in. And over here we have about 124 jobs that they can choose from. So on your side. Yes. Over here. Are they job opportunities? Jobs opportunities. So hopefully we're capturing them. Then at that point they'll tell us which job they want and then they'll get the corresponding budget sheet that has the job on it. And along with that job, say for architect for instance, it'll come with maybe that architect has a spouse. And then that spouse maybe they have kids. They could have one or two or three kids already. The ages are there and the names are there. Okay. Okay. Well, when we come back. Yes. We are going to continue to educate, motivate, and inspire students and the next generations. And we want every parent to grab their children and sit down and watch this episode. Absolutely. Wonderful. We'll see you when you come back. Wonderful. This is Think Tech Hawaii, raising public awareness. And lend your time or your voice to make breakfast happen for kids in your neighborhood. Aloha. I'm Marcia Joyner, inviting you to come visit with us on cannabis chronicles, a 10,000 year artisty where we explore and examine the plant that the muse has given us. And stay with us as we explore all the facets and facets of this planet on Wednesdays at noon. Please join us. Aloha. Next gen. Next gen financial. Welcome back to Sister Power with VIP guest Jeannie and Kathy. And we're talking about money management for the next generation. So this is a program, parents, students, high school students, even if you're in college. This is a program of the episode that you should watch. And Jeannie, walk us through the Get Real Financial Reality Fair. Well, for us at Hawaii USA, we are such proud partners with Kathy and her team at the foundation. And what we love about it is not only are we an educators credit union, we've been in business since 1936. We believe in the fact of just giving that information and sharing it with the younger folks because we believe that they are leading the future and we need to better empower them with these skills. So being that we are educators credit union, we partner with her team. We send out a call to action for volunteers and then we're proposing to meet needs and be at one of these 14 or 15 tables for Kathy and her team. And they're so well oiled, we walk in and we're taught to upsell these folks and be real. Car dealers aren't going to give you a special rate. Even Kathy's husband wants. He said, welcome to Fast Joe's Auto. Come on down. And he's selling cars like crazy. And the amazing part is, this is what happens in the real world. They're not going to give you a budget. You may say, no, no, I'm not the Escalade type. I'm the Camry. You're leaving with an Escalade. So it's just kind of educating and working together as a partner with the foundation to give them the tools because at the end of this event, we're sharing with them. It's not just your mom and dad every month. If they're arguing and there's problems over finances, what happened when prom comes up? All these additional finances they don't think of. I don't. Well, Kathy, at the reality fairs, do you talk about student loans? Oh, yes. Depending on the job that they chose, if that job required some type of college education, on their budget sheet is already an amount for their student loan debt. So some of them come with student loan debt, some of them come with credit card debt, and some come with both already. So when they get their budget sheet, we let them know, here's your family, here's how much you make, and this is after taxes. And by the way, you already have some student debt and you already have some credit card debt. Now go ahead and have fun. Build your house. And we just, we send them off and they can go at any table that they like. One of the things that we have, we have a wheel of reality, which is a random life event. And as we all know, things happen to us. So is the wheel, is this the wheel at the end? That is the wheel. This is the wheel here that the students get at the end. Where is the wheel here? Okay, over here. This is our wheel that the students get at the end of the program. And so the wheel talks about career, health, home, tech, debt, family, play, cash, all those things that happen to us. Like one of the items on the wheel is a speeding ticket. And so if they spin the wheel and depending on where they land, then they pull a card and anything could happen. It's a 50-50 shot, either adding money to their budget or taking away. And this is one of my favorite stories because when they get the one that says that they have a speeding ticket, it's $200. And they was like, this is not real. I said, oh yeah, it is. It is real. These things happen. And they was like, you mean I just lost $200? And I played with them. Well, you shouldn't have been speeding. Speaking from experience. I kind of am. It sounds like it's a little personal. I kind of am. I've been there. And really, that's why I love this program because I can say that I've been in financial situations where I've had to struggle. And we all have. And so if we can give our students just a little bit of reality to let them know that, hey, this is what's going to happen. However, it's manageable. It doesn't matter how much money you make. It matters what you do with the money you make. And we teach them that. Hallelujah. That's real. Jeannie, how do you help students get organized? We like to start out with, we have, for example, what Kathy mentioned about Waipahu High School when we first met. We've had a credit union inside of Waipahu High School for 21 years. So what we like to do is we'll go out, have an actual student-run credit union in their facility. We're in the facility. They can open accounts. They can make deposits. They can learn to write checks because nowadays everything's electronic and digital. So we have to teach them how to write checks. So we have student-run credit unions that our credit union supports. And we go out into the community. We have them on Maui as well. We're working with our Hilo branch. And we like to go out and just share this information because they're in our community as well. So we want to make sure we perpetuate that same message. Well, how do you prepare the students to choose a bank or credit union? How do you walk them through that? Well, personally speaking at Hawaii USA, we actually have in the student-run credit union. We had one at a high school and we were asking how come the kids weren't opening accounts? Well, we had found out that they're from students from Vietnam, from Samoa, from all different places, Philippines. And we were asking, what was the drawback? They didn't have a state ID. So to make plans, we went ahead and pulled up online where to get the state ID. How much does it cost? What buses get you there? Because we can't just assume it's down on Fort Street. Where's Fort Street? So we have to make sure we give those tools so that they're educated enough to apply for an ID to be able to start establishing an account and start that saving pattern when they're young.  Well, we have one coming up on October 24th. It's going to be at McKinley High School. And then also on October 24th, we will be on the Big Island at K. Owl High School. Is that on a Saturday or Sunday? That's during the week. Oh, during the week? It's during school hours. That's right. It's during school hours. When you go into the auditoriums, who do you meet with first to have this set up? The first thing we meet with, it depends. Most of the time it's a teacher, and then they bring in the principal and vice principal. And then I meet with all of the folks that will be associated with it in the school, answer all of their questions. One of the reasons we're even able to go into the schools is because it's purely and strictly an educational effort. We do not go in, you know, selling anything. We go in partnering to help our next generation. And that's what they love about it. And so once I meet with them, answer all their questions, then I meet with the credit union to see if that's something that they want to sponsor and host. And she always says yes, most of the time. Weakness.  We met when we were doing... Valentine's Day for Hawaii veterans. Valentine's Day for Hawaii veterans. And Hawaii USA along with Jeannie, we gave hundreds and hundreds of bags. And again, thank you for that. That was so wonderful. And we've been sisters from another mother ever since. Ever since. Ever since. And what was cute is that relationship where you needed something. We were hoping to fill 50 bags, for example, with shaving supplies, things veterans would need. And I am a military brat. So I emailed a couple dentists that banked with us. Dentists. I said I need toothbrushes, toothpaste. And then I called somebody else that had. And it was 125. Awesome. And then we all wore red and showed up at the hospital. And it was just, I still have a picture that is just memorable to me of a veteran. I started to bring all the pictures. And I said we'll do that another time. People who know me, they know that I have an organization called Sisters Empowering Hawaii, Hawaii's foremost women's empowerment organization. And our mission is to motivate, educate, and empower all women. And what I love about the two of you, you're going out to the schools and you're educating and you're motivating and you're inspiring the next generation not only to take care of themselves, but they're at the age that now we're going to be taking care of our parents like we're doing now. Absolutely. So you're getting them started on the right road. So give us something that we have not covered. One of the things that I would love to share is when the students finish, they fill out an evaluation. And this is where we get a chance to see if what we're doing is having an impact. And I can pretty much say out of every fair that we have done, there's someone that will say, I now know it costs too much to have kids. I don't want them right away. Or they'll come back and they say, I need to understand the difference between my needs and my wants. And that is one of the main things that we want to get them to understand. You can manage a budget and just because you can't afford it right now doesn't mean you can't afford it later. But do what you can now. And so those evaluations, we give them back to the schools so that they can see the impact that their students are having along with what careers they chose. So the schools are able to see and think what the kids are thinking because they don't think like we do. They don't reason like we do. And seeing them interact with each other and one of the things I love and I've noticed this, like she said in the very beginning, they're on their cell phones, right? Well, when they begin the fair, those cell phones are up. They are communicating with each other. They're socializing with each other. And the best part, they're talking finances. So for that two and a half hours period, we have their undivided attention and they are talking to one another. And it's about finances. And it's like, that's one of the best things to see them put that phone. Or they may use it for addition, like a calculator. But for that moment, we've captured them. Well, you know, ladies, we always have to have a part two. There's so much information. I appreciate you, Kathy, and I appreciate you, Jeannie, for coming in and educating our students. And on behalf of Sisters in Power and Hawaii, I would like to offer the both of you a $5,000 scholarship. It's a $5,000 Argosy University Scholarship. Congratulations from Sisters in Power and Hawaii.  So that's $10,000. And I would love to hear from you because they can use this up until 2020. And let me know, and let's take the students on a tour of Argosy University. I have that connection with them. And we can do that. And we can start them off with something wonderful to start them off going to school if they're not able to go away for school immediately. Sisters in Power and Hawaii, along with Hawaii, USA, and Get Rail reality, is just a win-win situation. Finally, join the movement. Only 20 days left until the general election on Tuesday, November 6th. Absentee ballots drop this week, with early voting beginning October 23rd. When we all vote, we can change the world. When we all vote, we determine our future. Tune in to Sister Power on Thursday at 4 p.m. I'm Sharon Thomas Yarbrough, your host. And at the end, I am a voter. So vote, November 6th. Thank you.


We are going to have Professor Fukumoto first, but then the next speaker is Dr. Professor Ajetsu, as planned. So Professor Fukumoto is switched from tomorrow Friday to this session. And he's going to give us his talk here. OK. So the title of my talk is Gyroscopic Analogy of Coriose Effect for Stabilizing Rotating Stratified Floors Confined Analysphaloid. And we are considering about how our Rayleigh-Teller instability can be stabilized by rotation possible, try to get some insight into the mechanism. The effect of stabilization by rotation can be clearly understood by the dispersion relation of waves in a rotating stratified fluid. This is a continuous stratification with a brand visceral frequency is constant. Then you get following dispersion relations. This is Coriose Effect called inertial waves. This is gravity effect, this is internal gravity waves. Then without Coriose Effect, if n square is negative, it means unstable stratification, waves can be unstable. But by imposing rotations, system rotations, it tells you can stabilize the gravity waves. Then for short waves in 2D horizontal directions, gravity waves compete with winds through the rotation effect. But for long waves in the horizontal directions, stabilization by rotation can be possible. And we will see this effect in two ways. One is a toy model of a continuous stratification of linear flow confined in a spheroid. In the second part, we look into the Rayleigh-Teller instability. I was much influenced by this book by the late professor Dolce and Schiis. And the translator by both heathens describes how Poincare's idea is extended to the present day. Using a business approximations, you can construct some exact solutions of the Ibn Nabiya-Souk's equations. And consider a spheroid of the general spheroid. Then we assume incompressibilities. And density is divided into the uniform one and just small perturbations. And by taking the gradient of this continuity equation, you get a following form of the continuity equations for the gradient of the densities. And momentum equation or Euler equation in the business approximation can take this form by taking the color. And this looks like a torque and called Baroclingi torque. Then you can construct a steady solution of these business equations. This satisfies also the boundary conditions at the spheroidal walls. Then for general flows, you may pause following a solution form and substitute this into the Nabiya-Souk's equations because we assume linear flows. This question doesn't work. Then you obtain following the equations. It's constructed by multiplying these small omegas. A capital omega is actually the rotations. And also, actually, the vortices. Capital omega is vortices. And small omega is cooked from this. And this is the equation governing the heavy top in the frame fixed to the body. Omega is angular velocity. M is angular momentum. And this L0 is in the language of the body, just the axis from the fixed point to the gravity centers. And now, built from the frame fixed to the bodies, direction of gravity is rotating. This direction of gravity is represented by sigmas. In the language of fluids, sigma is coming from the gradient of the densities. And this top axis is associated with angle from the gravity direction of the principal axis. Then this torque comes from a Baruchnik effect. And this comes from the Coriolis effect. For example, for simplicity, if you consider upright spheroid, and then also consider the symmetric top. And when you apply the case, this top axis is simply directed in the g-axis, built from the body frames. Then there are two steady solutions. One is this component, this third component is one. This corresponds to the unsafe certifications. And this is actually sleeping top. And the other steady solution is this simply is gravity is just below the center of gravity is below the fixed point. Then as you may well know, stability of sleeping top is obtained in these following criterions by rotating faster than this critical speed. Sleeping top is stabilized. But if friction slower the rotation, and the rotation speed is smaller than this critical values, then tops just stop their rotating motion. Then motivated by this analogies, you can consider the stability of the flow confined in the tilted spheroid. And in this case, the top axis, it means the axis connecting from the fixed point to the center of gravity is misaligned with a symmetric axis. And this top axis built from the body coordinate looks like this. And this is actually when tilted, integrability is lost. And stability is influenced by this misalignment between symmetry axis and top axis. And you can easily find a steady state. This is just one parameter for families. And stability of this state can show how alignment effect phi non-zero will change the stability of the well-known sleeping top of Lagrangian case. First, we consider prolet case. Prolet case is elongated like a rugby ball. Then its feature is first inertia tensor, a component of inertia tensor is larger than a third one. And stability shows when there's no tilt, no misalignment, this is well-known critical point. And if you rotate top faster than this value, it is stable. When tilted, the stability region is larger than applied case. And more tilted, stability region is more tonically greater. And when just a tilting angle is half pi, entire region becomes stable. And this is a relation between the real part of frequency and the imaginary part. And this is a critical point. And this is a case of 60 degree of tilting angles. And when floating speed is slower than this value, where the two eigenvalues are degenerate, then instability starts. Again, another bifurcation occurs for very small values. Well, obliquely, there are more tricky behaviors. Actually, when denominator becomes 0, steady solution is lost. And first, if this is a gross rate, if a lot of speed is slower and slower, and if it becomes slower than these critical values, instability starts. And gross rate diverges. But at this point, steady solution is lost. But again, there is another bifurcation. And gross rate behave like this. And bifurcation also occurs around here. There is two regions. And by gaining insight into the stabilized mechanism by the analogy with top or gyroscopic effect, you can consider the two phase flows, the lateral instabilities. That's a simple upright sueloid. Just there is an idea. Rotation doesn't affect instability because this is unrelated with energies. But actually, this gyroscopic effect has a pronounced influence for the stabilizations. This is an interesting experiment made by Skiers of Nottingham. And rotation speed becomes 0 and becomes faster. Then by very ingenious method, they could realize the lateral environment. Then for faster rotation case, instability is delayed. And motivated by this, we consider the mechanism for the stabilizations. There are several pioneering works for rotational stabilizations. First, it was made by Carnibere and Professor Orlandy. And they focus on the effect of correlative force on vortex rings. Then there are recent works by Tower. And you see the Baldwin experiment. And also, they made beautiful theoretical works. Skip one slide. Then the experiment is a cylindrical apparatus. And we consider the two-layer fluid is confined in the lower half of the sueloid. This corresponds to considering the effect of topography. Heavy fluid is lying on top of light fluid. We consider oil equations in a rotating frame. And then there is equilibrium shape. And this interface shape is given by this form. And to consider this form is very important. And we consider stabilities. Then the equation for the small perturbation of the interface is given by Zeta. And you may consider following representations for the velocity using the potential. And then pressure is automatically obtained by this. And substituting these into incompressible conditions, you get a well-known equation governing potentials. This type of wave equation has inertial waves and inertial waves and internal gravity waves. The boundary condition is just flow through the wall. And also, no singularity on the central axis. And as the interface, pressure is continuous. And the kinematic boundary condition should be satisfied. And we want to know the growth rate. And then you may assume of the linear stability. Then you may assume the normal mode. Governing equation becomes this form. Then you may solve this equation with the boundary conditions in the following form. Yes, this is just for pressure continuity across the interface. Takes this form and kinematic boundary condition takes this form by substituting perturbation into the boundary conditions. And we use a variational method. It's initiated by miles. Then scarce and the collaborator uses this. And we follow these beautiful techniques. By multiplying the governing equation, this obtains a variation function, functionals. Actually, you can check by taking variation with respect to potential. You obtain the potential equation. Also, exact solution satisfies phi itself equals 0. Then by substituting a solution, partly satisfying this boundary condition on the walls. But without satisfying the boundary conditions in the interface, you may obtain by reducing this integral, you may obtain following form. Here, axiomatic mode is simple. And you may assume following form by taking n equals 0. And formally, this will constitute a complete set of functions. Then the parameter a is the radius around here is common, come from here. And you can substitute this and take variation with the amplitude c. And you obtain the equations. But for simplicity, you may first consider the very slow system rotation case. Then you can get dispersion relation for this slow rotation case. Here, a is the same as at number. Delta is aspect ratio of the swearloin. And this is gross rate with horizontal axis of rotation speed normalized in this. And this blue is the result of half swearloin case. And the red one is aspect ratio is 4.1. This is oblate swearloin. And horizontal axis is four times longer than just symmetric axis. And blue one is this one. And then more oblate. If oblateness increases, you have larger stable regions. And this dotted and this dashed is a cylindrical case derived by scales and their cloverators with same aspect ratios. Yes, delta. Delta is, I should write down delta. Delta is now one. Oh no, yes, I'm sorry. Delta is aspect ratio. This is 4.1 and 2.1. And this and this is same aspect ratio. And this and this aspect ratio is 2 and 1. Compared with swearloin and cylinders, you can see swearloin is more stable region has a wider than cylindrical case. For prolet swearloin, it means this symmetric axis is longer than horizontal axis. Then swearloin case and the cylindrical case is not much different. Red one is 1.4, blue one is 1.1. This is the interpretations for elongated or prolet and more elongated means inertia moment in the horizontal direction is greater than inertia moment in the actual directions. Then critical speed for stability of sleeping top is increased. Therefore, more elongated is more unstable. And oppositely, if flattened, this is more overlaidness is increased. It means if she's increased, top is more stable. And you can interpret this from the stability of this top. Then finally, you can calculate the critical rotation rate for swearloin to establish stability of these two layer fluids. Then critical speed means this omega gross rate imaginary part omega equals 0. Then you may assume following. Then by taking this in power series of this small parameter and substitute this approximation, approximated eigenfunctions into this and taking the variations, you obtain critical rotation speed. Then the result is following. If you assume the same parameter used by experiment of scales, then you obtain critical rotation speed for the swearloin and this aspect ratio, I should write the aspect ratio somewhere, is this parameter. And I think almost one, 0.7 something, but I should write down. Then with same aspect ratios, you obtain the following critical rotation speed. And the case, the critical rotation speed for making establish stability is following. Then swearloin case can establish stabilization with lower rotation speeds. This is just the same graph as we showed previously. Summarize, we consider how a courier's effect can stabilize or can sustain heavy fluid on top of a light fluid. In the first part, we consider uniformly certified flow or linearly certified flow with velocity proportion linearly in coordinates. Then we looked at stability of the flow in tilted swearloin. And this is the same as the stability of the heavy symmetric top with top axis and the symmetric axis misaligned. Then in the second part, we consider regular instability of rodent flow confined in an upright half swearloin compared with a finite cylindrical case. Swearloin has a more stable environment. Thank you very much.


Live from San Jose, California, it's theCUBE, covering innovating to fuel the next decade of big data. Brought to you by Western Digital. Hey, welcome back everybody. Jeff Frick here with theCUBE. We are at the Western Digital headquarters in San Jose, California. It's the Almanac campus, a historic campus that's had a lot of great innovation, especially in hard drives for years and years and years. This event's called innovating to fuel the next day of big data and we're excited to have a big brain on like you get smart people who's been watching this story for a while and will give us a little bit of historical perspective. It's John Ridney, he is the research vice president for hard drives for IDC. John, welcome. Hey, thank you, Jeff. Absolutely. So what is your take on today's announcement? I think it's a very meaningful announcement, especially when you consider that the, you know, the previous big technology announcement for the industry was helium about four or five years ago, but really the last big technology announcement prior to that was back in 2005, 2006, when the industry announced making this transition to what they called at that time perpendicular magnetic recording. And when that was announced, it was kind of a similar problem at that time in the industry that we have today where the industry was just having a difficult time putting more data on each disk inside that drive. And so they kind of hit this technology wall and they announced perpendicular magnetic recording and it really put them on a new S-curve in terms of their ability to pack more data on each disk and, you know, just kind of put it in some perspective. So after they announced perpendicular magnetic recording, the capacity per disk increased about 30% a year for about five years and then over really a 10-year period increased about an average of about 20% a year. And so today's announcement is, I see a lot of parallels to that, you know, back when perpendicular magnetic recording was announced, you know, really the ability to increase the capacity per platter was growing very slowly. That's where we are today. And with this announcement of MAMR technology, the direction that Western Digital's choosing, you know, it really could put the industry on a new S-curve in terms of putting more capacity, storage capacity on each one of those disks. It's interesting, it always reminds me kind of back to the OS and Microsoft and Intel battles, right? Intel would come out with a new chip and then Microsoft would make a bigger OS and they would go back and forth and back and forth. And we're seeing that here, right? Because the demands for the data are growing exponentially. I think one of the numbers that was thrown out earlier today that the data thrown off by people and the data thrown off by machines is so exponentially larger than the data thrown off by business, which has been kind of a big driver of IT spin and it's really changing. So it's a huge fundamental shift. They had to do something, right? Yeah, the demand for storage capacity by these large data centers is just phenomenal. And yet at the same time, they don't want to just keep building new data center buildings and putting more and more racks. They want to put more storage density in that footprint inside that building. So that's what's really pushing the demand for these higher capacity storage devices. They want to really increase the storage capacity for cubic meter inside these data centers. It's also just fascinating that our expectation is that they're going to somehow pull it off, right? Our expectation that Moore's laws continue, things are going to get better, faster, cheaper and bigger. But at the back in the back room, somebody's actually got to figure out how to do it. And as you said, we hit these kind of seminal moments where you do get on a new S curve. And without that, it does flatten out over time. You know what's interesting though, Jeff, is really about the time that perpendicular magnetic recording was announced way back in 2005, 2006. The industry was really already at that time talking about these thermal assist technologies like MAMR that Western Digital announced today. And it's always been a little bit of a question for those folks that are either in the industry or watching the industry like IDC and maybe even more importantly for some of the HGD industry customers. They're kind of wondering, so what's really going to be the next technology race horse that takes us to that next capacity point? And it's always been a bit of a horse race between Hammer and MAMR. And there's been this lack of clarity or kind of a huge question mark hanging over the industry about which one is it going to be? And Western Digital certainly put a stake in the ground today that they see MAMR as that next technology for the future. Since you just read a quote today, Sargillai Keeble alumni just took a new job and he's got a pin tweet at the top of his thing and he says a smart man looks for ways to solve the problem or looks at new solutions. The wise man really spends his time studying the problem. And it's really interesting here because I don't know, it seems kind of obvious there. He's never necessarily a good thing with electronics and data centers. As you mentioned, we're trying to get efficiency up. There's pressure as these things have become huge, energy consumption machines. That said, they're relatively efficient based on other means that we've been doing to compute and the demand for this compute continues to increase, increase, increase, increase. So as you kind of look forward, I mean, is there anything kind of any gems in the numbers that maybe those of us at the layman level are kind of a first reader missing that we should really be paying attention to give us a little bit of a clue of what the future looks like?  One is that, you know, at least for the hard drive industry, if you kind of look back the last 10 years or so, you know, a pretty significant percentage of the revenue that they've generated, a pretty good, you know, percentage of the petabytes that they ship, they've really gone into the PC market and that's fundamentally shifting. And so now it's really the data center so that, you know, by the time you get to 2020, 2021, about 60 plus percent of the petabytes that the industry shipping is going into data centers where, you know, if you look back a few years ago, 60 percent was going into PCs. That's a big, big change for the industry. And it's really that kind of change that's pushing the need for these higher capacity hard drives. Right. So that's, I think, one of the biggest shifts that's taking place. Well, the other thing that's interesting in that comment because we know scale drives innovation better than anything. And clearly, you know, Intel and microprocessors rode the PC boom to get on scale to drive the innovation. And so if you're saying now that, you know, the biggest scale is happening in the data center, then, you know, that's a tremendous force for innovation in there versus, you know, flash, which is really piggybacking on the growth of these jobs because that's where it's getting its scale. So when you look at kind of the flash hard drive comparison, right? Obviously flash is the shiny, the shiny new toy getting a lot of buzz over the last couple of years. Western Digital has a play across the portfolio. But, you know, the announcement earlier today said you're still going to have like this 10X cost differentiation. Yeah, that's right. Even through, I think it was 2025, I don't want to say what the numbers were over a long period of time. You see that kind of continuing, you know, DC, any kind of conflict between those two or is there a pretty clear stratification between what's kind of going to flash systems or what's going to hard drive systems? That's a great question. So even in the very large hyperscale data centers, we definitely see where flash and hard disk drives are very complementary. You know, they're really addressing different challenges, different problems. And so, you know, I think one of the charts that we saw today at the briefing really is something that we agree with strongly at IDC. Today, maybe about seven or 8% of all of the combined HGD SSD petabytes shipped for enterprise are SSD petabytes. And then that grows to maybe 10. Like seven percent? Six to seven percent. Yeah, so you still have 92, 93%, 94% of all petabytes that again are HGD and SSD petabytes for enterprise. Those are still HDD petabytes. And even when you get out to 2020, 2021, you know, again, still about 90%, we agree with what Western Digital talked about today, about 90% of the combined HGD SSD petabytes that are shipping for enterprise continue to be HDDs. So we do see the two technologies very complementary.  They, you know, really are going to quickly continue to become a bigger slice of the storage devices attached to new PCs. But in the data center, you really need that bulk storage capacity, the low cost capacity, and that's where we see that the two SSDs and HDDs are going to live together for a long time. Yeah, and as we said, the complementary nature of the two different applications are very different. You know, you need the big data to build the models, to run the algorithms, to do stuff, but at the same time, you need the fast data that's coming in, you need the real-time analytics to make modifications to the algorithms and learn from the algorithms. That's right, yeah. So it's the two of those things together that are one plus one makes three type of solution. Exactly, and especially to address latency. Everybody wants their data fast. When you type something into Google, you want your response right away, and that's where SSDs really come into play, but when you do deep searches, you're looking through a lot of data that has been collected over years, and a lot of that's probably sitting on hard disk drives. Yeah, the last piece of the puzzle I just wanted to address before we sign off, which I thought was an interesting point, is not just necessarily the technology story, but the ecosystem story, and I thought that was really kind of, I thought the most interesting part of the MAMR announcement was that it fits in the same form factor, there's no change to OS, there's no kind of change in the ecosystem components in which you plug this in. Yeah, that's right. It's just you take out the smaller drive, the 10 or the 12 or whatever, or 14 I guess is coming up, and plug in, they show out a picture of a 40 terabyte drive. That's the other part of the story that maybe doesn't get as much play as it should. You're playing in an ecosystem. You can't just come up with this completely, kind of independent radical new thing unless it's so radical that people are willing to kind of swap out their existing infrastructure. I completely agree. It can be very difficult for the customer to figure out how to adopt some of these new technologies. And actually, the hard disk drive industry has thrown a couple of technologies at their customers over the past five, six years that have been a little challenging for them to adopt. So one was when the industry went from native 512-byte sectors to 4K sectors, seems like a pretty small change that you're making inside the drive, but it actually presented some big challenges for some of the enterprise customers and even the shingled magnetic recording technology. So it is a way to get more data on the disk and Western Digital certainly talked about that today, but for the customer trying to plug and play that into a system and SMR technology actually created some real challenges for them to figure out how to adopt that. So I agree that what was shown today about the MAMR technology is definitely a plug and play. All right, I'll give you the last word as people are driving away today from the headquarters. They got a bumper sticker as to why this is so important. What's it say on the bumper sticker about MAMR? It says that we continue to get more capacity at a lower cost. Isn't that just always the goal? Isn't that great. All right, well, thank you for stopping by and sharing your insight. I really appreciate it. Thanks, Jeff. Jeff Frick here at Western Digital and you're watching theCUBE. Thanks for watching.


Hello everybody, my name is Gunther and I will be your host for Let's Watch, Let's Play. This is Freedom's Weekly Let's Player Showcase where we show you gamers from the YouTube to deserve some praise. First up this week is The Champ. The Champ plays titles like Slenderman Must Die, Transistor, and The Forest. Those are just a few titles that The Champ plays a lot of other shorter and smaller games. What I like most about his channel is his enthusiasm because he really really enjoys the stuff that he does. I got excited watching him get excited about what he was doing and that's great engagement for a Let's Player. Go check him out by clicking on any of these things here. Next up this week is Easton, a console gamer with a golden voice. Easton plays Halo, Fallout New Vegas, and L.A. Noir on his channel. That's actually the entirety of his video collection, but he did just start a new series of Halo's anniversary edition with a brand new capture card so I expect more to come in the future. His commentary is very soothing and pretty awesome given that he has the amazing voice of a boring commentator. You will be jealous of it, but you will also enjoy his work. Check out these videos to see more of it. Last this week is Sharkbait. Her name is derived from the fact that she actually works with sharks for her job. Fearless as anyone who quite literally is Sharkbait on a daily basis, she plays horror games like Outlast, Neverending Nightmares, and Eyes. Sharkbait is quite the character and is very entertaining on her videos. It's apparent that she uses her channel for fun and from what I saw the viewer gets just as much out of it as she does. So if you're looking for more fear in your life, grab a cup of tea and check out more of her videos here. Introducing a new segment of the show is something I'm calling Gunther's Tip of the Week, where I'll be explaining a general piece of advice that all Let's Players out there can take to heart to improve their channel. This week's tip is audio mixing. Some audio and vocal audio need to not overpower one another and still be discernible to the viewer. Good audio, audio that doesn't overmodulate or make your eardrums pop, keeps us watching. Try recording game and vocal audio on separate channels and mixing them together later. The same goes for adding music or other videos to your work. Make all of your audio work together. I recommend everyone to edit your audio as much as if not more than your video. That wraps up this week's episode everybody. To check out any of the feature gamers, click on the channel links here. If you're a gamer and you're looking to be featured in an upcoming episode, leave a comment down below about your channel. Thanks so much for watching, see you. Oh, oh, oh no, oh where are we going, no.


Hi my dear friends, welcome back to Plants and Lucia. My name is Lucia and this beautiful plant right here is Edith. Today we're gonna talk about the beautiful golden photos. Okay, coming up. Oh, before I forget, if you're watching this video in July of 2020, we're celebrating our first 10,000 subscribers. So we're doing a giveaway, of course, to say thank you. If you would like to participate, make sure to check out this video right here for all the information. But now, let's get to this beauty right here. The golden photos actually comes from South Asia, so it is a tropical plant. And it has a reputation of being one of the easiest houseplants to take care of. I can tell you for me, this plant just brings me joy because she's so easy to care for and so beautiful. And really, it is very beautiful. This plant is actually known for its leaves. The leaves have the shape of a heart, and they have some golden tones to them. So you see some green, and then some gold. Hence the name. If you keep this plant happy, it will grow up to 10 feet long. And that's indoors. She's also such a special plant to have indoors because it has the capability to purify the air. So we actually have our photos in our bedroom, just to purify the air while we sleep. And it's just so beautiful to wake up to. So now, let's see how you can keep your beautiful photos very happy at your house. In terms of temperature, this plant will be very happy in normal household temperatures. So keep her in a room that is between 15 to 20-something degrees Celsius. This is a tropical plant, so they would like humidity. They don't need as much humidity as the Galaxy as, for example, that in my experience need about 60% humidity. I think normal levels of humidity should be okay. If you find that in the winter, the air in your place is super dry, and you see that the edges of your leaves are browning, your plant may need a bit more humidity. So place her with other tropical plants on a humidity tray or close to a humidifier. One important factor with the golden photos is light. Remember, the golden photos doesn't need so much sunlight. I find that they're happy with medium or low light levels. Avoid bright direct sunlight because this may burn the leaves. So for example with ours, as I said, we have them in our bedroom. Our bedroom actually has a north-west facing window, which is perfect for her because she gets afternoon sunlight but really indirectly. And she seems to be thriving there. I've learned that this plant likes low to moderate watering. We don't want to give too much water to our plant because we don't want to overwater her. So the way that I check if my plant needs water is with my finger. I put my finger inside the soil until the second knuckle or until the end of my finger. And once I feel that the soil is dry, then I water. And the method that I use, of course, is the bottom watering method. I love this method, as you may know, because it helps me get the water into the roots from below. And then once I'm done, I actually let the water drain down through the drainage holes. The soil is moist but not super wet. And she seems to be very happy like this. In the winter, you will notice that the soil takes longer to dry out. So cut back on water. Remember, we want to let the soil dry in between waterings, so we don't overwater our plant. In terms of fertilizer, I'm actually fertilizing my plant pretty much every time we water during the growing season, which is from spring to summer. I fertilize every time we water because we use an organic fertilizer. And organic fertilizers tend to be less concentrated than synthetic fertilizers. But of course, even if you have an organic fertilizer, I strongly recommend that you check the instructions on the package. That way you make sure that you don't overfeed your plant. And this is the fertilizer we use right now. I really love it because it's vegan and organic. And our plants seem to be very happy with it. So if you would like to try it out, I will just put a link in the description down below so you can find it. And actually, I want to show you how many new leaves we have in this plant because, oh my God, it's growing super nicely. So let me show you now. In terms of potting mix, this plant is super adaptable. So you can use an all-purpose house plant potting mix. If you want to make your own, I would recommend that you add seven parts of coconut coir, two parts of worm castings, and two parts of fred light. In terms of toxicity, when we prune our plant, there may be some sap coming out of the stem. This sap can be irritating to the skin. So just be careful. Okay, my friends, these are some of the tips that I can give you about this beautiful plant. Do you have a golden potos at home? How do you take care of it? Make sure to comment below so we can all learn together. Of course, if you would like to be part of this community, you're always welcome. So make sure to subscribe so we can see each other every week and talk about plants. And as always, I will see you in the next video. Okay, ciao!
