226 Stringfellow, Gerald B.Control of ordering in Ga0.5In0.5P using growth temperatureThe kinetic processes leading to ordering in Gas,, In o.4P8 have been studied by observing the effects of substrate misorientation (O-9), growth rate (0.1-0.5), and substrate temperature (570- 670 "C) during growth. The ordered structure and degree of ordering are determined using transmission elec...Ordering Structure; Growth Temprature; Growth Rate1994
227 Furse, Cynthia M.Prof. James R. wait and mining production technology--an appreciationProf. James R. Wait examined electromagnetic (EM) wave propagation in many situations of interest to mining production, including propagation in tunnels, propagation along extended conductors such as cables and drill stems, and propagation in coal seams.

229 Myers, Chris J.ILP-based scheduling for asynchronous circuits in bundled-data implementationIn this paper, we propose a new scheduling method for asynchronous circuits in bundled-data implementation. The method is based on integer linear programming (ILP) which explores an optimum schedule under resource or time constraints. To schedule descriptions with many operations,our method approx...2006
230 Furse, Cynthia M.; Gandhi, Om P.Computations of SAR distributions for two anatomically-based models of the human head using CAD files of commercial telephones and the parallelized FDTD codeThe Finite Difference Time Domain (FDTD) method is well suited for the computation of bio-electromagnetic effects and has become the method of choice for most researchers in this area. There does however remain some limitations on its use. Firstly the FDTD method requires large amounts of memory and...Finite-difference time-domain method; FDTD; SAR distributions; CAD files1997
231 Tasdizen, TolgaPrincipal components for non-local means image denoisingThis paper presents an image denoising algorithm that uses principal component analysis (PCA) in conjunction with the non-local means image denoising. Image neighborhood vectors used in the non-local means algorithm are first projected onto a lower-dimensional subspace using PCA. Consequently, neigh...2008
232 Stringfellow, Gerald B.Nitrogen surfactant effects in GaInPThe addition of surfactant nitrogen during the growth of GaInP on 001 GaAs substrates produces significant and interesting changes in the optical and morphological properties of GaInP. In particular, multiple peaks are seen in the low temperature photoluminescence (PL) spectra of GaInP/GaInP:N he...Surfactant nitrogen; Microscopy; Crystals2004
233 Furse, Cynthia M.; Cotter, Neil E.Challenges in curriculum adaptation across institutions of higher education: international and national student transferThe challenges associated with student transfer between institutions of higher education are investigated.

237 Mathews, V. JohnParallel-cascade realizations and approximations of truncated volterra systemsAbstract This paper introduces parallel-cascade realizations of truncated Volterra systems with arbitrary, but finite order of nonlinearity. Parallel-cascade realizations implement higher-order Volterra systems using parallel and multiplicative combinations of lower-order Volterra systems. Such rea...1996
