Technical Papers and Presentations

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

Composite systems are becoming more and more widespread across industries and the capability to finding and tracking internal defects before they have grown to major deterioration is of paramount importance in regard to safety, economy and maintenance. We are exploring a novel method of ... Read More

In a magnetic resonance imaging (MRI) system, it is necessary to excite the nuclei of a patient into coherent precession for imaging. This requires a coupling between the nuclei and a source of radio frequency (RF) power using a transmitter. To receive a meaningful signal, we also need ... Read More

Increasing demand for new technology, products and processes to provide improved performance, achieve proof of concept quicker, offer higher quality and meet demands for on-time and on-budget delivery have put increasing pressure on scientist and engineers to predict performance before ...
