Switching circuit energy balance in iLabs on experimental lab server architecture

[摘要] In Electrical Engineering courses, it is important that students have hands-on experience with a circuit and components to witness their behavior and compare it with theoretical models. The MIT iLab Project develops online laboratories that allow students to perform experiments through a web browser from anywhere in the world. One such lab used in the Introduction to Circuits class, the NMOS Resistor Amplifier Lab, allows students to analyze the switching waveforms of a transistor. This thesis describes the integration of a thermal camera to the NMOS-Resistor Amplifier Lab to educate students about energy dissipation. The first version of this lab, built entirely in LabVIEW, on iLabs;; existing Shared Architecture could not support an interactive lightweight client. In response, the Experimental Lab Server Architecture (ELSA) was developed as a new interface connecting an experiment, client, and Service Broker. In the first prototype of the Thermal Lab in ELSA, a Java Applet Client uses REST calls to send commands and acquire data from the LabVIEW experiment running on the server.
