Knowing the magnetic fields generated by an assembly of magnets in epicyclic motions are important in designing magnetrons for physical vapor deposition (PVD) applications [1]. Epicyclic paths would mean all magnets are rotating in an orbital (central) axis, on top of which each magnet ... Read More

Common mode chokes are good EMI filters in electronic power systems [1]. For such devices, values for their impedance are critical to their performances as noise filters. In this study, a two-step finite element approach is employed to study the impedance variations of a ferrite-core ... Read More

Electroplated CoFe alloys demonstrating Joule magnetostriction (i.e., a large change in material shape induced by an applied magnetic field) have been recently developed for the creation of microfabricated magnetoelastic resonators for tagging applications. This development requires a ... Read More

The process of cold drawing a fiber over rollers is analyzed in this work to predict the temperature rise due to the heat generated during plastic deformation of the fiber. Experimental measurements on prototypes indicated an unacceptable temperature rise of greater than 100 F requiring ... Read More

In a recent publication (Limitations of Breakthrough Curve Analysis in Fixed-Bed Adsorption, Ind. Eng. Chem. Res. 2016, 55, 4734-4748) the authors discussed the a priori prediction of the axial dispersion coefficient from available correlations versus obtaining it and also mass transfer ... Read More

This paper presents the design and simulation of novel micrometer-scale capacitive temperature sensors, which could serve as a component for miniaturized wireless sensor nodes for the internet of things requiring structural flexibility and optical transparency. The proposed sensor design ... Read More

Concrete hydration is a highly exothermic process which, in large concrete structures, produces highly elevated temperatures. While this phenomenon has long been understood to be a negative side effect which can cause thermal stress cracking in concrete structures, a relatively new and ... Read More

Drilled shafts are cylindrical, cast-in-place concrete deep foundation elements used for heavy structures such as highway bridges and tall buildings. Construction involves drilled excavation of soil or rock using large diameter augers to form a deep cylindrical void, placement of the ... Read More

Syringes were first conceptualized in 1650, but were invented in 1853 by Dr. Alexander Wood. As of 2011, nearly 8 billion syringes are used each year in the United States for medical purposes (not including veterinary services). These syringes are used for diseases like diabetes, ... Read More

Finite element models for acoustic scattering from three dimensional underwater elastic objects, calculated in the frequency domain, are transformed to the time domain through Fourier synthesis using COMSOL Multiphysics®. The time domain mirrors the way in which experimental scattering ... Read More
