The previous articles in this series [1, 2] described how the mean and standard deviations of a set of data are calculated and how they can be used to estimate the characteristics of a population using the normal distribution. Since measured data typically represents only a subset of an entire population, one should recognize that the estimated mean and standard deviation … [Read more...]

Fan Cooling – Part 1: Determining Flow Rate
Authored by Ross Wilcoxon and Genevieve Martin Associate Technical Editors for Electronics Cooling For a number of reasons, including cost, simplicity, power consumption, noise, etc., natural convection is the preferred approach for cooling electronic systems. However, it is often the case that natural convection is simply not sufficient to remove dissipated power … [Read more...]
Statistics Corner: Regression Analysis
Throughout their careers, engineers and scientists are all likely to encounter and utilize the results of regression analysis, which is “a set of processes for estimating the relationships between a dependent variable and one or more independent variables” [1]. In other words, regression analysis uses a set of data to estimate a relationship between the independent … [Read more...]
Real-Time Prediction of Li-Ion Battery Pack Temperature
Co-Authored by: Dr. Azita Soleymani and William Maltz The global shift to electric vehicles (EV) is coming and, unless an alternative technology emerges, it will be fueled by high-capacity lithium-ion (li-ion) batteries. Making the hundreds of millions of li-ion batteries the world will eventually need for e-mobility is a massive undertaking full of technical challenges. … [Read more...]
