Design and implementation of a simplified Kalman filter for an ocean circulation model

Creator:: Yao, Yunda
Abstract:: A Kalman filter was developed to recover information on short period variations of ocean circulation from the satellite altimeter signals for the North Pacific Ocean. The ocean circulation at each grid point is specified by three variables: sea level height h, zonal velocity u, and meridional velocity v. In our...

Lightweight Corefile Browser

Creator:: Muddarangegowda, Manjunath
Abstract:: One of the main problems in debugging parallel programs is in determining how far a parallel program has executed when it crashes or stops. Even if the program dumps core files for all the parallel processes, the information is at such a low level that it is difficult to interpret...

Porting and optimizing a routing library for Dataparallel C on the nCUBE 2 system

Creator:: Sivaramapuram, Krishna
Abstract:: Dataparallel C has been designed for various kinds of architectures and was developed jointly at University of New Hampshire and Oregon State University. This project dealt with porting the libraries to the nCUBE 2 system and helping a user compile his programs on nCUBE 2 directly from a Sun workstation...

General purpose, client configurable fuzzy logic expert control system

Creator:: Huntley, Kyle
Abstract:: In this paper we describe a fuzzy logic based control system implemented on a PC architecture. The rule based inference engine of this expert system is easily configured through an ascii text file and is demonstrated to be capable of controlling various simulations, including an inverted pendulum. The controller is...

Integrating multimedia mechanism into object-oriented framework Objex

Creator:: Liu, Rui
Abstract:: The problem addressed in this paper is that of the extension of multimedia mechanism into Objex, an object oriented framework. Several multimedia productions have been developed recently, such as QuickTime™, HyperCard, MacSpeaker, Multi-Ad Creator 3.0, etc. [Heid 91]. The common problems with them, however, are that they are all implemented...

An integrated assembly tolerance analysis system

Creator:: Qian, Xiaonong
Abstract:: Tolerance analysis and synthesis plays a vital role in the success of a product design because it directly affects product quality and manufacturing cost. It also affects manufacturing process selection and planning. This research provides a review of several commonly used assembly tolerance analysis models and evaluation of their limitations....

Subsurface Quaternary and Pliocene structures of the northern Los Angeles Basin, California

Creator:: Hummon, Cheryl
Abstract:: The northern Los Angeles basin is influenced by two structural styles: the west-trending compressional Transverse Ranges to the north, and the strike-slip Peninsular Ranges to the south. The interaction of these two structural styles has resulted in a complex fold fault belt at the northern margin of the Los Angeles...

Study of interfacial condensation in a nuclear reactor core makeup tank

Creator:: Ma, Chang Chun
Abstract:: Steam interfacial condensation in a core makeup tank was simulated using the code RELAP5/MOD3 version 8.0 to predict the violent pressure oscillation phenomena in a core makeup tank. Six base cases were carried out to study the effects of back pressure and of vacuum conditions produced in the core makeup...

Residence time distribution of solids in a multi-compartment fluidized bed system

Creator:: Pongsivapai, Pajongwit
Abstract:: In a conventional well-mixed fluidized bed the solids are almost completely mixed and the residence time for individual particles may vary between zero and infinity. For materials especially sensitive to the processing time, a wide distribution of residence time is extremely undesirable. A multi-compartment fluidized bed was proposed to minimize...

Field evaluation of passive capillary samplers in monitoring the leaching of agrochemicals

Creator:: Brandi-Dohrn, Florian M.
Abstract:: Soil solution samplers have certain inadequacies that limit their range of possible applications. Passive Capillary Samplers (PCAPS), which apply suction to the soil pore-water via a fiber glass wick, have shown promising results in preliminary experiments in regard to collection efficiency of water and of bromide tracers. The objectives of...

A low cost AC motor drive for battery powered applications

Creator:: Wiley, Brian
Abstract:: Environmental concerns have renewed the interest in electric vehicles. To gain widespread use, electric vehicles will also have to offer good performance and be reasonably priced. AC drive systems using modern semiconductors can provide efficient operation at the required power levels, but their cost at present is still too high....

Large subunit of vaccinia cirus ribonucleotide reductase : affinity chromatography-based purification and photoaffinity labeling

Creator:: Warth, Rainer K.
Abstract:: Ribonucleoside diphosphate reductase (RR) from vaccinia virus was recently cloned and overexpressed rn Escherichia coli. The amino acid sequence identities of the small and large subunits between the mouse and the vaccinia virus reductase are approximately 80 and 72 percent, respectively. In addition, vaccinia virus RR displays similar complex allosteric...

Small sample, low-temperature calorimetry

Creator:: Wolochuk, Lee
Abstract:: A calorimeter capable of measuring the heat capacity of 1 mg size samples from 4.2 to greater than 100 K has been designed, constructed, and tested. The sample is bonded to the end of a 0.002 inch diameter, 0.5 cm long chromel-constantan thermocouple (type E) and heated optically with a...

A low ground bounce CMOS off-chip driver design

Creator:: Zheng, Jieyin
Abstract:: With the advancement of technology, submicron CMOSonly process is available now for Application Specific Integrated Circuits (ASICs). The high integration leads to the need for high pin counts. However voltage supply and ground bounce due to many output drivers switching at the same time is becoming a major problem. In...

A library for doing polyhedral operations

Creator:: Wilde, Doran K.
Abstract:: Polyhedra are geometric representations of linear systems of equations and inequalities. Since polyhedra are used to represent the iteration domains of nested loop programs, procedures for operating on polyhedra can be used for doing loop transformations and other program restructuring transformations which are needed in parallelizing compilers. Thus a need...

The extraction of pentachlorophenol from pressure treated wood using supercritical carbon dioxide

Creator:: Yi, Jung-Seok
Abstract:: The extraction of pentachlorophenol (PCP) from pressure treated wood wafers with supercritical carbon dioxide has been studied. Experimental data were obtained for the effects of pressure (17.5 - 25.0 MPa), temperature (313 - 353 K), flow rate (1 - 3 ml/min at supercritical conditions), and sample size (0.8 x 10...

Influence of channel constraint on primary production, preiphyton biomass, and macroinvertebrate biomass in streams of the Oregon Coast Range

Creator:: Zucker, Steven J.
Abstract:: Differences in primary production and periphyton and macroinvertebrate biomass between pairs of constrained (valley floor width of less than twice the active channel width) and unconstrained reaches were investigated in Elk River and four tributaries in southwest Oregon. In August 1991, macroinvertebrates were sampled from individual cobbles, and rocks were...
