A Technique for the Measurement of Relative Velocity between Parallel Plate Electrodes in Micromachined Structures

Dean, Robert (2006-05-15)

Numerous applications exist for microstructures that contain two parallel oriented electrodes that experience relative motion. It is often desirable to measure the relative velocity between the two electrodes and then ...

Time-frequency sonar detection of elastic wave reradiation

Thompson, Matthew (2023-12-06)

This work examines the effectiveness of quadratic time-frequency methods in exposing the presence of elastic wave reradiation in active sonar returns. Elastic wave reradiation here means the coupling of elastic surface ...

Timely Inference over Networks

Shisher, Md Kamran Chowdhury (2024-04-29)

Next-generation communications (Next-G), such as 6G, are expected to support emerging networked intelligent systems, including autonomous driving, factory automation, digital twin technology, unmanned aerial vehicle (UAV) ...

Timely Remote Estimation and Applications to Situational Awareness

Ornee, Tasmeen Zaman (2024-04-29)

In real-time monitoring and networked control systems, sensor observations from vehicles, robots, UAVs, or stock markets, are transmitted to a monitoring or controlling unit, which could be any kind of decision-making ...

Topics in Multisensor Maneuvering Target Tracking

Jeong, Soonho (2005-08-15)

Tracking uses models of the real environment to estimate the past and present and even predict the future state of a moving object from noisy observations of uncertain origin. In a tracking scenario the most critical ...

Toward Zero Backtracks in Test Pattern Search Algorithms with Machine Learning

Roy, Soham (2021-07-19)

A digital circuit with n primary input lines has N = 2^n possible input vectors and a test vector that detects a fault in the circuit may be among those 2^n n-bit combinations. A pure random test generator can generate ...
