Glossary Attenuation. definition: Attenuation is the process of water retention on site and slowly releasing it in a controlled discharge to a surface water or combined drain or watercourse. The amount of discharge will vary depending whether it is a brown or greenfield site.

correlation correlation. n. 1. a mutual or reciprocal relationship between two or more things. 2. the act or process of correlating or the state of being correlated. 3. (Statistics) statistics the extent of correspondence between the ordering of two variables. Correlation is positive or direct when two variables move in the same direction and negative or inverse when they move in opposite directions. [C16: from Medieval Latin correlātiō, from com-together + relātiō, relation]. (ˌkɔr əˈleɪ ʃən, ˌkɒr-). n.

Punctuation For other uses, see Punctuating (disambiguation). Punctuation is the use of spacing, conventional signs, and certain typographical devices as aids to the understanding and the correct reading, both silently and aloud, of handwritten and printed texts. In written English, punctuation is vital to disambiguate the meaning of sentences.

Currency Devaluation and Revaluation Currency Devaluation and Revaluation. 1  Under a fixed exchange rate system, devaluation and revaluation are official changes in the value of a country's currency relative to other currencies. Under a floating exchange rate system, market forces generate changes in the value of the currency, known as currency depreciation or appreciation. In a fixed exchange rate system, both devaluation and revaluation can be conducted by policymakers, usually motivated by market pressures.

What is a hypoattenuating lesion? Hypoattenuation is a term used to describe areas that show up as whiter and brighter than normal on an x-ray or CT Scan. Hypoattenuating lesions are commonly referred to in regards to the liver or kidneys.If your doctor looks on your CT scan and spots an area on your kidney or liver that is whiter or brighter than it should be, this is a hypoattenuating lesion.The lesion could be a sore or a cyst, but it could also be the sign of something more serious, such as a tumor. hypoattenuating lesion is a type of abnormal tissue that can show  up on computed tomography. On the scan, the lesion shows up as  brighter and whiter than what is conside … red normal. The lesion can  indicate an array of medical issues and it warrants further  investigation. + 6 others found this useful.

Mass diffusivity For other uses, see Diffusivity (disambiguation). Diffusivity or diffusion coefficient is a proportionality constant between the molar flux due to molecular diffusion and the gradient in the concentration of the species (or the driving force for diffusion). Diffusivity is encountered in Fick's law and numerous other equations of physical chemistry.

- A relationship between two variables in which one variable increases as the other decreases, and vice versa.In statistics, a perfect negative correlation is represented by the value -1.00, while a 0.00 indicates no correlation and a +1.00 indicates a perfect positive correlation.A perfect negative correlation means that the relationship that appears to exist between two variables is negative 100% of the time. relationship between two variables in which one variable increases as the other decreases, and vice versa.

Introduction Standard Deviation (Volatility) Standard deviation is a statistical term that measures the amount of variability or dispersion around an average. Standard deviation is also a measure of volatility. Generally speaking, dispersion is the difference between the actual value and the average value. The larger this dispersion or variability is, the higher the standard deviation. The smaller this dispersion or variability is, the lower the standard deviation. Chartists can use the standard deviation to measure expected risk and determine the significance of certain price movements.

attenuation attenuation. The loss of signal strength with long distances when signals travel along cabling. Attenuation values for actual cables are measured in units of decibels (dB) a standard measurement value used in communication for expressing the ratio of two values of voltage, power, or some other signal-related quantity.

What is Attenuation? Attenuation refers to the reduction in the strength of a signal over distance. Think of the sound comming from your speaker. If you are standing right next to your speaker, the sound is very loud and strong. But, the farther you move away, the quieter the sound gets. Eventually, you won't be able to hear it at all.

Tips and Tricks for Using Oil Lamps Knowledge of your weight fluctuation means you will consider weight loss when you have exceeded the bottom end of your fluctuation, similar to weight gain... this is one of the reasons why I don't believe in weighing in every 7 days... there's just no way of knowing what end of the fluctuation you are on at the moment.

Correlation The correlation is one of the most common and most useful statistics. A correlation is a single number that describes the degree of relationship between two variables. Let's work through an example to show you how this statistic is computed.

Attenuation This article is about attenuation in physics. For other uses, see Attenuation (disambiguation). In physics, attenuation (in some contexts also called extinction) is the gradual loss in intensity of any kind of flux through a medium. For instance, dark glasses attenuate sunlight, lead attenuates X-rays, and water attenuates both light and sound.

Australian Bureau of Statistics If we consider the two variables price and purchasing power, as the price of goods increases a person's ability to buy these goods decreases (assuming a constant income). Correlation is a statistical measure (expressed as a number) that describes the size and direction of a relationship between two or more variables. A correlation between variables, however, does not automatically mean that the change in one variable is the cause of the change in the values of the other variable. Causation indicates that one event is the result of the occurrence of the other event; i.e. there is a causal relationship between the two events.

- Correlation is the measure of the extent to. which a change in one random variable tends to correspond to change in the other random. variable. For example, height and weight have a moderately strong positive correlation.

- Deindividuation is one social psychological theory used to explain aggression. Deindividuation suggests that a person loses their inhibitions because they are no longer identifiable and so finds is easier to act in an aggressive way.

negative correlation Part of the Business intelligence-business analytics glossary: A negative correlation is a relationship between two variables such that as the value of one variable increases, the other decreases. Correlation is expressed on a range from +1 to -1, known as the correlation coefficent. Values below zero express negative correlation. A perfect negative correlation has a coefficient of -1, indicating that an increase in one variable reliably predicts a decrease in the other one.

Attenuation Definition - What does Attenuation mean? Attenuation is a telecommunications term that refers to a reduction in signal strength commonly occurring while transmitting analog or digital signals over long distances. Attenuation is historically measured in dB but it can also be measured in terms of voltage.
