Antireflection Of An Absorbing Substrate By An Absorbing Thin Film At Normal Incidence, R. M.A. Azzam, E. Bu-Habib, J. Casset, G. Chassaing, P. Gravier

Electrical Engineering Faculty Publications

An absorbing substrate of complex refractive index n₂ - jk₂ at wavelength λ can be coated by an absorbing thin film of complex refractive index n₁ - jk₁ and thickness d to achieve zero reflection at normal incidence. For given n₂,k₂ multiple solutions (n₁,k₁,d/λ) are found that correspond to infinitely many distinct antireflection layers. This is demonstrated for a Si substrate at two wavelengths (6328 and 4420 Å). The response of these absorbing antireflection layers to changes of the angle of incidence from 0 …

Fast Thermal Generation Rescheduling, F. Eugenio Villaseca, B. Fardanesh

Electrical and Computer Engineering Faculty Publications

A new dynamic programming algorithm for fast rescheduling thermal generation is presented. The savings in computational times are brought about by the introduction of two new techniques: the variable truncation dynamic programming and the limitation of the solution space to be searched. Several examples on a 20 machine system are used to illustrate the application of the algorithm and to show that optimal solutions are obtained at significantly reduced computational times.

Edge Direction Confidence Estimation For Improvement Of Hough Accumulation, Eric J. Grajales

Retrospective Theses and Dissertations

The Hough transform silhouette identification method requires a consistency of edge direction in the identification of similar silhouettes. Many gradient operators used in Hough preprocessing require a thresholding and a non-maxima suppression routine to aid the localization process. These routines may delete edges or cause edge fragmentation. These anomalies degrade the Hough performance due to the lack of accurate silhouette extraction, and reduce the correct localization in the Hough accumulator. Noise or sampling errors can be removed by several enhancement routines presented. They are mean, median, symmetric nearest neighbor, hi pass, and low pass filters.

An edge detection process is …

Mechanical Engineering Faculty Research

A method for calculating power transmitted to the hands of operators who use vibrating hand tools is presented. Results that relate to a comprehensive multidiscipline NIOSH field study of several hundred chipper and grinder workers who used pneumatic hand tools are discussed. These results indicated that the total power in the frequency range of 6.3 to 1000 Hz transmitted to the hand ranged from 1080 to 7230 J/s for the chisel and from 0.852 to 157 J/s the handle of chipping hammers. For pneumatic grinders the power transmitted to the hands of the tool operators was in the range of …

Experimental And Theoretical Studies On Design Calculations For Latent Heat Storage, Dieter Lindemann

Open Access Theses

Research was conducted to obtain design data of latent heat-of-fusion thermal energy storage (LHTES) devices. The devices studied utilize a porous medium (PM) to increase the effective conductivity of the storage system. Therefore the melting and freezing process is accelerated. Metal shavings and metal spheres were used as porous media and water as the phase change medium (PCM). A simple experimental method to measure the conductivity of a water-metal mixture or ice-metal mixture was applied to obtain conductivity data. These measurements can be considered fairly accurate because measured conductivity of pure water and of pure ice agreed very well with …

Enthalpies Of Solution Of Co2 In Aqueous Methyldiethanolamine Solutions, Keith E. Merkley

Theses and Dissertations

The enthalpies of solution, H^S, of carbon dioxide in aqueous methyldiethanolamine were measured with an isothermal flow calorimeter over wide ranges of temperature, pressure, weight percent MDEA, and loading (gmole CO₂/gmole MDEA). The values of H^S (kJ/gmole CO₂) were found to be constant up to the saturation concentration of CO₂ in the aqueous solution. In addition, experimental data showed that H^S was independent of the total pressure over the solution, but linearly dependent upon both temperature and weight percent MDEA as was given by a correlation. A computer program based upon …

Diffraction Modelling For Saw Devices On Anisotropic Substrates, Melanie A. Roberts

Retrospective Theses and Dissertations

This thesis presents two approaches to solving the diffraction problem for SAW devices on anisotropic substrates. Diffraction is a nonlinear second-order effect which alters SAW performance, and some of the difficulty in predicting the actual effect is the anisotropy of acoustic materials, which makes the Fresnel Integral solution non-trivial. An accurate model for diffraction effects will allow compensation to be made without iterations in expensive and time consuming fabrication and testing processes, especially since it is difficult to isolate diffraction from other second-order effects. Of the two methods of modelling, one is a Fresnel Integral evaluation approach, and the other …

Colorimetric Assay For Methanesulfinic Acid In Biological Samples, Charles F. Babbs, Melissa J. Gale

Weldon School of Biomedical Engineering Faculty Publications

We describe a simple colorimetric method to measure 30 to 300 M concentrations of sulfinic acids in biologic samples. The procedure employs the coupling reaction of an aromatic diazonium salt (Ar-N=N+) with the sulfinic acids (RSOOH) to produce a colored diazosulfone derivative (Ar-N=N-SOOR), which can be selectively extracted into an organic solvent. Linearity and noninterference by liver homogenate, phenols, amines, and thousand-fold or greater excesses of sulfate, thiol, and dimethyl sulfoxide are demonstrated. Sensitivity of the method is about 10 nmol per sample. Because methanesulfinic acid is the principal product of the action of hydroxyl radicals upon dimethyl sulfoxide, and …
