This research establishes a method of analyzing the equations that describe pollution problems employing a digital computer program previously in existence, the IBM Electronic Circuit Analysis Program (ECAP). In this ...

This thesis is concerned with passive control systems for seismic protection of building structures, with special emphasis on elastomeric bearings, viscous dampers and tuned mass dampers. Both mathematical modeling and ...

Two models were incorporated to evaluate the hydrologic and hydraulic behavior of the Harris Gully watershed in Houston, Texas. A HEC-1 model was created and calibrated to three historical storms for average errors of 6% ...

The spectral element method is used to obtain 3D, time-dependent solutions for a thermocapillary driven liquid bridge with magnetic stabilization, which arises from the float-zone crystal growth process. The methods and ...

Low-energy electron transfer between a Rydberg atom and a target molecule can result in formation of long-lived metastable negative ions. Here we describe a novel permanent-magnet Penning trap designed to examine the ...

Harmonic drive gear reducers were developed during the mid-1950's and are used in many industrial and military applications. The harmonic drive is a compact, "in-line" gear reducer capable of producing reduction ratios of ...

We present a computational approach for constructing Sylvester style resultants for sparse systems of bivariate polynomial equations. Necessary and sufficient conditions are derived which guarantee that a multiplying set ...

A new course designed to introduce freshmen to civil engineering and to give non-engineers a taste of engineering was developed and taught. The course is divided into four sections (demand, design, construction, and effects) ...

The tremendous increase in Raman-scattered photons seen in Surface-Enhanced Raman Scattering (SERS) has led to its adoption as a common analytical laboratory tool in spite of lingering questions about the phenomenon. One ...

Robots are increasingly found to operate together in the same environment where they must coordinate their motion. Such an operation is simple if the motion is quasi-static. Under second-order dynamics, the problem becomes ...
