Introduction to compressive sensing. This course introduces the basic concepts in compressive sensing. We overview the concepts of sparsity, compressibility, and transform coding. We then review applications of sparsity in several signal processing problems such as sparse recovery, model selection, data coding, and error correction. We overview the key results in these fields, focusing primarily on both theory and algorithms for sparse recovery. We also discuss applications of compressive sensing in communications, biosensing, medical imaging, and sensor networks. (less)

An introduction to several fundamental ideas in electrical engineering and computer science, using digital communication systems as the vehicle. The three parts of the course - bits, signals, and packets - cover three corresponding layers of abstraction that form the basis of communication systems like the Internet. The course teaches ideas that are useful in other parts of EECS: abstraction, probabilistic analysis, superposition, time and frequency-domain representations, system design principles and trade-offs, and centralized and distributed algorithms. The course emphasizes connections between theoretical concepts and practice using programming tasks and some experiments with real-world communication channels. (less)

In this two-part activity, learners work in pairs to examine the four basic stages of a turbine engine. During the first part of the lesson, learners visit three stations: Combustion, Compression, and Intake to discover what happens as different forces act on air. In the second part, learners build a model of a turbine engine. This activity emphasizes the scientific method including prediction, observation, data collection, and analysis. This lesson plan includes instructions on how to set up the stations, discussion questions, diagrams, black-line masters, and sample worksheets for learners. (less)

Using spaghetti and marshmallows, students experiment with different structures to determine which ones are able to handle the greatest amount of load. Their experiments help them to further understand the effects that compression and tension forces have with respect to the strength of structures. Spaghetti cannot hold much tension or compression; therefore, it breaks very easily. Marshmallows handle compression well, but do not hold up to tension. (less)

Students take a hands-on look at the design of bridge piers (columns). First they brainstorm types of loads that might affect a Colorado bridge. Then they determine the maximum possible load for that scenario, and calculate the cross-sectional area of a column designed to support that load. Choosing from clay, foam or marshmallows, they create model columns and test their calculations. (less)

Rocks cover the earth's surface, including what is below or near human-made structures. With rocks everywhere, breaking rocks can be hazardous and potentially disastrous to people. Students are introduced to three types of material stress related to rocks: compressional, torsional and shear. They learn about rock types (sedimentary, igneous and metamorphic), and about the occurrence of stresses and weathering in nature, including physical, chemical and biological weathering. (less)

In this activity, learners build scaled-down structures and cantilevers in a series of "building out" challenges with bamboo skewers and tape. In doing so, learners will experience many of the basic physics and engineering concepts inherent in structures as well as explore the concepts of torque and center-of-mass. This resource guide contains background information, discussion questions and extensions. This activity is a scaled-down version of the "Garden Poles--Building Out" activity (see related resource).

Students learn why shock absorbers are necessary on vehicles, how they dampen the action of springs, and what factors determine the amount of dampening. They conduct an experiment to determine the effect of spring strength and port diameter on the effectiveness of a shock absorber. Using a syringe, a set of springs, and liquids of different viscosities, students determine the effects of changing pressures and liquids on the action of a model shock absorber. They analyze their data through the lens of an engineer. (less)
