Using Lecture Demonstrations to Visualize Biological Concepts

INTRODUCTION The use of visual aids in biology has traditionally focused on laboratory activities and demonstrations (3, 6, 8, 12, 15–18). However, a limited number of authors have suggested activities suitable for lectures. Such activities reinforce the concepts taught and require less equipment, time, and expense than laboratory activities Moreover, simple demonstrations are easy for students...

Spatial Econometrics using MATLAB

Toolboxes are the name given by the MathWorks to related sets of MATLAB functions aimed at solving a particular class of problems. Toolboxes of functions useful in signal processing, optimization, statistics, finance and a host of other areas are available from the MathWorks as add-ons to the standard MATLAB software distribution. I use the term Spatial Econometrics Toolbox to refer to my publi...

Explaining Convolution Using MATLAB

Students often have a difficult time understanding what convolution is. Students can often evaluate the convolution integral (continuous time case), convolution sum (discrete-time case), or perform graphical convolution but may not have a good grasp of what is happening. In other words, students can solve the formula but often do not understand the result or why they get that result. Most engin...

OFDM Simulation Using Matlab

Orthogonal frequency division multiplexing (OFDM) is becoming the chosen modulation technique for wireless communications. OFDM can provide large data rates with sufficient robustness to radio channel impairments. Many research centers in the world have specialized teams working in the optimization of OFDM for countless applications. Here, at the Georgia Institute of Technology, one of such tea...
