OBJECTIVE AND BACKGROUND Objective monitoring of cough may be preferred to subjective reporting of the symptom in clinical and research settings. Therefore, a self-contained, ambulatory cough monitoring system is needed that is non-invasive, usable for children and adults of all ages, inexpensive, and highly accurate with easy to use analysis software.

This numerical study presents a detailed optimal control design based on the general finite element approach for the integrated design of a structure and its control system. Linear quadratic (LQ) theory with output feedback is considered on the basis of the state space model of the system. Three-dimensional finite elements are used to model the smart(More)
Improvised explosive devices (IEDs) represent one of the most significant and deadly threats faced by armed service personnel and innocent civilians in current conflicts. Related threats refer to terrorists and suicide bombers who have caused large numbers of civilian deaths in non-war settings such as 9/11 and the commuter train bombings in the United(More)
The finite-element method of analysis is unrestricted by size considerations and is well suited for the study of very small structures such as MEMS devices embedded in structures. This paper presents the numerical approach and results for a silicon-based micro-flow sensor for pulsed-flow sensing. The new approach presented here is the treatment of transient(More)
