The motivation for this work is to explore the combination of a multiphysics COMSOL model of the wing of the Pathfinder Plus research aircraft with a wavelet-based vibration detection scheme. COMSOL Multiphysics is utilized to model the physics of the aerodynamics that produce vibration in the wing structure of the Pathfinder Plus. Next, three Daubechies wavelets are used to detect the ...

Efficient, effective, and functional operation of autonomous systems requires a comprehensive real-time understanding, by those systems, of the embedding environment. This paper presents a brief overview of the multiphysics considerations involved in the development of models for thermoresistive and magnetoresistive sensors systems.

Atherosclerosis affects the arterial blood vessels causing stenosis in the arteries because of which the artery hardens resulting in loss of elasticity in the affected region. In this paper, we present an approach to model the pulsating flow of blood through such an atherosclerosis affected region of the artery using the finite element method. We further discuss the statistical model used to ...

This paper reports a strategy to design a network of higher immunity and capacity of recovery to faults or other destructive events. The capacity of survivorship and recovery increases when the system possesses some redundancy, and this means sources and lines and switching capability that are able to take over areas that loose connectivity to their parent source. Therefore, a second network, ...

The inverse problem of electrocardiography involves determining information about the electrical activity of the heart from measurements on the body surface. The estimation of certain physiological parameters can potentially improve early detection of heart disease. In this study, we present an algorithm for estimating parameters that characterize the electrical activation. Estimation of ...
