A backpropagation scheme with and without boosting, 1999

 Item — Call number MU Thesis Pro
Identifier: b2088058
Abstract Neural networks, simply stated, are machines that learn. A neural network consisting of several neurons, which are modeled after the human brain, uses synaptic weights, or interneuron connection strengths, to store acquired knowledge, which can be used in the future. One form of neural networks, feedforward networks, uses multilayer perceptrons, which are layered sets of neurons. This type of network contains an input layer, one or more hidden layers, and an output layer. Further, these...

Adaptive simplex procedures for function minimization, 1970

 Item — Call number MU Thesis Mas
Identifier: b2088116
Abstract This thesis investigates a class of direct search methods for system optimization where it is assumed that the dependent variable is a unimodal function of N independent variables. The best optimization procedure is that which requires the least number of evaluations of the dependent variable. It is assumed that either the function or its derivative is unknown. The basic form of the search techniques studied requires the establishment of (N + 1) test points in N dimensions. Three...

Boosting algorithm techniques and analyses, 1996

 Item — Call number MU Thesis Cat
Identifier: b2089046
Abstract The enclosed project contains the results of the research, analysis and testing of a Modified Boosting Algorithm to be used by a configuration of learning machines in order to perform regression. The algorithm is used to construct a set of "weak learners", whose individual performance is only slightly better than 50%, but whose ensemble performance is better than any one regression machine. The intent is to develop the algorithm and to demonstrate that it performs as well, if...

Computer modeling of radar performance, 1972

 Item — Call number MU Thesis Fel
Identifier: b2088560
Abstract This paper is an investigation into the development of a digital computer model that will enable a wide range of radar system configurations to be evaluated. The solution in the past has been to evaluate each system at a few salient points and leave the remaining parts of the problem to an intuitive development. Alternatively, a system is configured for the sole purpose of evaluating the system. The proposed model solution consists of the development of a digital computer...

Evaluation of the Wireless Internet Gateways (WINGS) and the Multimedia Support for Mobile Wireless Networks (MMWN) protocols, 1999

 Item — Call number MU Thesis Bal
Identifier: b2194993
Abstract The network technology employed in today's military tactical environment is largely based on commercial network technologies. These commercial technologies are designed to operate in a stable environment. However, many military situations arise that demand highly mobile networks. Communications on the move, continuity of operations when a critical node goes down, and instant communcations in areas lacking a communications infrastructure are just a few examples of situations requiring...

Multimodal search techniques, 1971

 Item — Multiple Containers
Identifier: b2087702
Abstract The purpose of this paper is to investigate the suitability of dynamic simplex search methods for finding the global extremum of multimodal functions. The search will be in N variable space with the form of the function unknown or in such a form that conventional techniques such as the calculus cannot be used. The initial search is conducted using the dynamic simplex method to find the first extremum. Three methods were evaluated for their usefulness in determining the global...

Recognition of spoken vowel sounds using a hybrid computer simulation, 1971

 Item — Multiple Containers
Identifier: b2088576
Abstract This paper will be an investigation into a hybrid computer simulation to recognize four (A, E, I, O) spoken vowels. The hybrid simulation makes available two modes of operation to achieve the recognition process. A learning mode will provide the algorithms required to categorize each vowel into parameters that can later be accessed by the second or recognition mode. The recognition mode takes the input vowel sound and correlates the recognition mode parameters against the learning mode...

Self similar traffic generation by method of Random Midpoint Displacement Algorithm (RMDA), 2002

 Item — Call number MU Thesis Huf
Identifier: b2089935
Abstract This paper explores an algorithmic means for simulating self-similar data traffic, which can be used to model broadband networks. The aim of this work is to create a traffic generator tool that generates stochastic self-similar traffic using a fast simulation technique known as Random Midpoint Displacement Algorithm (RMDA). Finally, the output of the RMDA traffic generator is evaluated for accuracy by using the Varience of Residuals method to compare the Hurst estimates to the actual...

Signal distribution control board for wireless applications, 2001

 Item — Call number MU Thesis Jac
Identifier: b2087774
Abstract Wireless communication testing occurs at baseband, intermediate, and radio frequencies. Chipsets that reside in base stations and mobile stations typically utilize baseband frequencies for signal processing of call set-ups and provided dedicated channels such as pilot, paging, synchronization, traffic, and data. These signals must be converted to radio frequency before they are transmitted to the wireless channel and received by the mobile station (forward link) or the base station...

Study and simulation of PLL carrier recovery techniques, 1999

 Item — Call number MU Thesis DiP
Identifier: b2088065
Abstract In the implementation of the wireless demodulator, numerous techniques exist to recover a carrier from the received signal. The selection of an appropriate recovery method depends on several conditions, among which are modulation type, acquisition time, tracking performance and the expected noise environment. This project first presents a discussion on the fundamental question of communications systems and includes sections on the transmitter, channel, and receiver. Receiver...
