Analysis and Evaluation of Register Transfer Logic Software Defined Radio Performance
The Register Transfer Logic Software Defined Radio (RTL-SDR) is a low-cost software-defined radio (SDR) built around a television tuner. Group 108 at MIT Lincoln Laboratory has interest in determining the potential capabilities of SDR receivers for air surveillance. Several RTL-SDRs were put through tests to compare their performance characteristics to those of the commercial Ettus Universal Software Radio Peripheral (USRP). Prototypes were built for both a two-channel and three-channel RTL-SDR system; these systems were tested for phase offset between their receiver channels. RTL-SDRs cannot compete directly on performance with more expensive SDRs specifically built for reception, but they show good performance for their price and can be utilized in a multi-channel receiver system

Sonification of Chemical Engineering Data
Chemical Engineering concepts are generally taught using visual learning methods, which may hinder students that prefer alternate learning methods. The purpose of this study was to determine whether auditory learners benefit from auditory-based feedback. Multiple steady states (MSS) and PID control were presented through auditory means by sonifying temperature and heat output data streams. Twenty-three students completed a survey to determine their preferred learning modes, an assignment that presented MSS and PID control through auditory means, and a post-survey to assess whether they learned the material from the auditory component of the assignment. The data suggested that auditory learners benefit from auditory-based feedback, though the results were not statistically significant
