Translating MATLAB scripts into SPMD-style parallel programs

Creator:: Seelam, Nagajagadeswar Reddy
Abstract:: In this report., we address the issues of translating MATLAB scripts into SPMD-style C programs. The resulting programs, when linked with our run-time library are suitable for execution on parallel computers. We describe the design of the compiler and improvements made to it in the current version. We also describe...

WebWEPP version 2.0 : Web-based water erosion prediction project

Creator:: Gyu Han, Hong
Abstract:: The WEPP (Water Erosion Prediction Project) application computes soil loss and sediment yield from a field based on the data on crops, management practices, and operations. In order to make WEPP, which is a Windows-based application, easily accessible, Web WEPP (Web-based WEPP) was developed by our research group. Web WEPP...

A pipelined baseband digital predistortion architecture for RF amplifier linearization

Creator:: Xu, Xiangqing
Abstract:: This thesis describes the design of a baseband digital predistortion architecture for radio frequency (RF) amplifier linearization. Existing amplifier linearization techniques are first examined. The nonlinearity of an amplifier can be characterized as amplitude-to-amplitude distortion and amplitude-to-phase distortion. The distortion can be corrected by providing a predistorted driver signal (both...

Porting GCC to X32V architecture

Creator:: Venkatachalapathy, Savithri H.
Abstract:: This thesis work evaluates the need for a re-configurable cross compiler for the X32V processor architecture and discusses the process of developing a cross compiler for X32V. X32V is a new processor intended at the embedded applications domain whose instruction set is designed based on the widely used MIPS processor....

Advanced time-varying approaches for modeling the multipath channel in wireless network

Creator:: Aljerme, Abdelkader A.
Abstract:: This dissertation proposes the use of advanced time-varying approaches for modeling the dynamics of the multipath channel in wireless communication networks. These advanced time-varying approaches include linear Kalman innovation models in observable block companion form, and neural network-based models. The e˙ectiveness of these type of models is evaluated through three...

Designing and understanding information retrieval systems using collaborative filtering in an academic library environment

Creator:: Jung, Seikyung
Abstract:: Accessing information on the Web has become ingrained into our daily lives, and we seek information from many different sources, including conference and journal publications, personal web pages, and others. Increasingly, web-based information retrieval systems such as web-based search engines, library on-line catalog systems, and subscription-based federated search systems are...

Dynamic and Dual Streaming Methods for H.264 Video and Parallel Performance Modeling

Creator:: Johnson, Taylor N.
Abstract:: Traditional approaches to streaming H.264 video over a network typically rely on a single method of transport (i.e., reliable or unreliable) and/or use static values for parameters that can have a significant negative impact on the perceptual quality of the received video. This dissertation presents a dynamic method for wireless...

Scheduling system of affine recurrence equations by means of piecewise affine timing functions

Creator:: Mui, Lap K.
Abstract:: Many systematic methods exist for mapping algorithms to processor arrays. The algorithm is usually specified as a set of recurrence equations, and the processor arrays are synthesized by finding timing and allocation functions which transform index points in the recurrences into points in a space-time domain. The problem of scheduling...

Implementation of processor allocation in an N-Cube multiprocessor on Macintosh

Creator:: Liu, Jinyue
Abstract:: The processor allocation in an n-dimensional hypercube multiprocessor using buddy strategy, gray code strategy, and a new strategy is implemented on Macintosh. Our implementations show that when processor relinquishment is not considered (i.e. static allocation), all these strategies are optimal in the sense that each incoming request sequence is always...
