Addressing Co-Channel Interference with PRK-Based Scheduling for Predictable Link Reliability in Wireless Networked Sensing and Control
Reliable wireless communication is a basic enabler for networked sensing and control in many cyber-physical systems, yet co-channel interference is a major source of uncertainty in wireless communication. Integrating the protocol model's locality and the physical model's high fidelity, the physical ratio-K (PRK) interference model bridges the gap b...

In-Cylinder Cycle-by-Cycle NOx Measuring Technique in Spark Ignited Engines
Currently, there is no technique that determines the quantity of NOx present at the end of the combustion cycle in spark ignited engines. Existing technologies for measuring NOx in spark ignited engines are limited to slow response sensors placed in the engine exhaust. Wayne State University researchers have developed a novel technique to determ...

Vibration Energy Harvesting Device Based on Air-Spaced Piezoelectric Cantilevers
WSU researchers have designed an energy harvesting device using an air-space piezoelectric cantilever instead of the piezoelectric bimorph. Current vibration energy harvesting devices typically employ piezoelectric bimorph or a bimorph with a shim in the middle. The use of the air-space cantilevers produces numerous advantages compared to conventio...
