. VSA’s would be an ideal addition to any undergraduate communicationslaboratory because of their ability to investigate the many types of signals prevalent today.Unfortunately, most VSA’s are priced well beyond the budgets of typical undergraduate ECEdepartments. This paper describes a novel low-cost VSA that uses basic PC data acquisition(DAQ) cards to capture signals of interest and real-time processing of signals with LabVIEWand MATLAB. This VSA system provides a user interface that has much of the basicfunctionality of standard hardware VSAs, but with the limitation that bandwidth is constrainedby the sampling rate of the DAQ. The system provides real-time plots of I/Q constellations. Wedescribe the user interface as well as example

was a search for a significant engineering concept related to solidification.The search started with defining and quantifying the process. If the process is done in a fluid (airor water), then convection is prominent and can be described in the equation below: q=Q/t=A*h*∆Twhere: q is the heat flow rate (amount of heat per time) Q is the amount of heat t is time A is the area of contact between the two objects (cast material and cast mold) h is the ‘film coefficient’ (related to the interface of cast and mold) and T is the Temperature (∆T is the change in temperature)Once the cast material (soap) and molds were chosen, the film coefficient and area is set.

In addition, Mathematica can find the EMfields in analytic form (with additional toolbox, Matlab can solve problems analytically too).One thing worth of mentioning is that both Mathematica and Matlab functions are case-sensitive.To use Mathematica, start with the command < Sqrt[x^2 +y^2], theta -> angle[x, y]}, {x, x1, x2}, {y, y1, y2}, opts]; ( example : PlotPolarVectorField[{r, Sin[q]}, {r, q}, {x, -1, 1}, {y, -1, 1

The flow is due to a driving potential: in heattransfer the driving potential is a temperature difference between two locations, while in the caseof electric current the voltage difference is the driving potential. The thermal resistance isobtained by employing this analogy and manipulating the heat transfer governing equations andcasting them in the form of Ohm’s law.For a plane thin wall with its two surfaces at constant, yet different, temperatures (Fig. 1), thesteady-state one-dimensional conduction heat transfer is given by Fourier’s law: T1 / T2 Q% ? k A (1
