It gives a thermal expansion coefficient of an ideal gas as (3)αV=1V(NkBP)=1T. In contrast to this universal behavior of ideal gases,αVof different solids may even vary qualitatively. However, it is remarkable that thermal expansion of crystals often has a temperature dependence similar to...
In subject area: Mathematics The clustering coefficient is defined as the probability that two neighboring vertices of a given vertex are also neighbors of each other, and may provide another useful feature to characterize instance difficulty for graph based problems like timetabling. ...

If we ignore the colors for a second, all 1,000 dots in this scatterplot visualize some population. Thepopulation correlation -denoted byρ- is zerobetween test 1 and test 2. Now, wecoulddraw a sample of N = 20 from this population for which the correlationr = 0.95. Reversely, this ...
Step 6: Multiply the value you got in Step 4 and Step 5. Step 7: Find the square root of the value you found in step 6. 3rd take the numerator and divide by the denominator.If you suspect a linear relationship between x and y, then r can measure how strong the linear relationship...

Small world networks have recently attracted much attention because of their unique properties. Mounting evidence suggests that communication is optimized in networks with a small world topology. However, despite the relevance of the argument, little is
When order K is equal to 0, the following process may be used to generate a bin string (e.g., a string of bins) using Exp-Golomb coding for a given non-negative integer x: 1. Record x+1 in binary. 2. Count the bits written, subtract one, and record that number of starting ...
