To teach students to work in teams. [4]

Investigate how to compare the mathematical model of a dynamic system with its experimental performance. [1, 2]
a. Evaluate the performance of heat sinks in mitigating temperature rise of microprocessor chips. Model the performance of heat sinks by developing a heat transfer based model. [1, 2] b. Experimentally measure the frequency response of a microscale cantilever. Understand how nanoscale metrology can be performed using an atomic force microscope and use it to evaluate the integrity of a manufactured memory storage device. Estimate the stiffness of microscale cantilevers by measuring the thermally induced deflections/oscillations of compliant cantilevers. [1, 2] c. Understand ideas related to signal acquisition (sampling theorems etc.) in addition to concepts related to Fourier analysis and power spectral density.
a. Determine the calorific value of transportation fuels using a bomb calorimeter and explore the sources of error and uncertainty in such measurements. Consider how the energy content of fuels and the efficiency of the energy conversion process through either spark ignition or compression ignition engines yields differences in overall vehicle fuel economy.
