Destination Tag Routing Techniques Based On A State Model For The Iadm Network, Darwen Rau, Jose A. B. Fortes, Howard Jay Siegel
Destination Tag Routing Techniques Based On A State Model For The Iadm Network, Darwen Rau, Jose A. B. Fortes, Howard Jay Siegel
Department of Electrical and Computer Engineering Technical Reports
A "state model" is proposed for solving the problem of routing and rerouting messages in the Inverse Augmented Data Manipulator (IADM) network. Using this model, necessary and sufficient conditions for the reroutability of messages are established, and then destination tag schemes are derived. These schemes are simpler, more efficient and require less complex hardware than previously proposed routing schemes. Two destination tag schemes are proposed. For one of the schemes, rerouting is totally transparent to the sender of the message and any blocked link of a given type can be avoided. Compared with previous works that deal with the same …

Preliminary Report On High-Performance Computational Structures For Robot Control, Mahibur Rahman, David G. Meyer
Department of Electrical and Computer Engineering Technical Reports
In this report we present some initial results of our work completed thus far on "Computational Structures for Robot Control". A SIMD architecture with the crossbar interprocessor network which achieves the parallel processing execution time lower bound of o( [a1n ]), where a1 is a constant and n is the number of manipulator joints, for the computation of the inverse dynamics problem, is discussed. A novel SIMD task scheduling algorithm that optimizes the parallel processing performance on the indicated architecture is also delineated. Simulations performed on this architecture show speedup factor of 3.4 over previous related work completed for the …

The objective of the project is to raise the understanding of dark current mechanisms in GaAs-related solar cells to a level comparable to that of silicon cells. Motivation for this work arises from the observation that much of the progress in crystalline silicon cell performance has occurred as a result of a very deep knowledge of the physics controlling the cell’s dark current. Based on this knowledge, new cell structures evolved to suppress dominant dark current mechanisms. A comparable level of knowledge of GaAs cell device physics does not yet exist, but will be essential if cell performance near the …

A Road Maintenance Management Information System For Counties And Cities, John D. N. Riverson, Charles F. Scholer, David Middendorf
Indiana Local Technical Assistance Program (LTAP) Publications
County Highway Departments in Indiana follow guidelines approved by the State Board of Accounts, mainly for highway resource accounting and not for maintenance activity costing. The existing Daily Work Report Form was modified to help maintenance activity costing with more precise reporting of road location, equipment and material use and also for storage on a microcomputer database. The Highway Extension and Research Project for Indiana Counties and Cities (HERPICC) at Purdue University tested the recommended procedures in a pilot project with White County Highway Department in Indiana, U.S.A.. A user-friendly program was developed using the R-Base 5000 database software for …

A Decomposition Approach For Balancing Large-Scale Acyclic Data Flow Graphs, P. R. Chang, C. S. G. Lee
A Decomposition Approach For Balancing Large-Scale Acyclic Data Flow Graphs, P. R. Chang, C. S. G. Lee
Department of Electrical and Computer Engineering Technical Reports
In designing VLSI architectures for a complex computational task, the functional decomposition of the task into a set of computational modules can be represented as a directed task graph, and the inclusion of input data modifies the task graph to an acyclic data flow graph (ADFG). Due to different paths of traveling and computation time of each computational module, operands may arrive at multi-input modules at different arrival times, causing a longer pipelined time. Delay buffers may be inserted along various paths to balance the ADFG to achieve maximum pipelining. This paper presents an efficient decomposition technique which provides a …

Behavior Of Mucks And Amorphous Peats As Embankment Foundations, Timothy Crowl, C. W. Lovell
Behavior Of Mucks And Amorphous Peats As Embankment Foundations, Timothy Crowl, C. W. Lovell
JTRP Technical Reports
The construction of highway embankments over deposits of amorphous peat and muck is made difficult by the low shear strengths, high compressibilities, and excessive amounts of creep typically associated with soils of this nature. This report begins with a review of the compression behavior of these soils, including a method for predicting embankment settlements from the results of laboratory tests. A soil testing program is then developed for the determination of parameters required for embankment design and construction. Field vane shear tests are recommended for the measurement of the undrained shear strength, and creep tests are recommended for calculation of …

A Non-Iterative Power Flow Study Technique Based On The Method Of Minimal Least Squares, Michael Carl Merow
Department of Electrical and Computer Engineering Technical Reports
A load flow study is used to determine the state variables of a power system. Load flow studies are essential for analyzing the effects of future load growth, for planning new facilities, and for the normal daily operation of the power system. The goal of this research is to examine an alternative load flow solution to be used in connection with the power system’s data acquisition system. Three standard linear power flow models are proposed which form a redundant set of linear equations. The equations make use of system measurements to help overcome errors introduced in the linear models. The …
The Harmonic Impact Of Rectifiers Serviced By Scott And Leblanc Connected Transformers, William P. Butler
The Harmonic Impact Of Rectifiers Serviced By Scott And Leblanc Connected Transformers, William P. Butler
Department of Electrical and Computer Engineering Technical Reports
Conventional three-phase, six-pulse rectifiers produce harmonic currents which propagate into the ac power system from which they are supplied. A two-phase, four-pulse rectifier can be operated such that there are no ac harmonic currents generated. In this connection, although there is no harmonic impact, the three-phase load current is imbalanced. The operation of a line-commutated two-phase, four-pulse rectifer [rectifier] served by the Scott and LeBlanc three-phase to two-phase transformer connections is simulated using a digital computer program in this thesis. Several different methods of rectification for a two-phase bridge are simulated and their current waveforms analyzed for harmonic content and …

Methods For Multisource Data Analysis In Remote Sensing, Jon Atli Bensdiktsson, Philip H. Swain
Department of Electrical and Computer Engineering Technical Reports
Methods for classifying remotely sensed data from multiple data sources are considered. Special interest is in general methods for multisource classification and three such approaches are considered: Dempster-Shafer theory, fuzzy set theory and statistical multisource analysis. Statistical multisource analysis is investigated further. To apply this method successfully it is necessary to characterize the "reliability" of each data source. Separability measures and classification accuracy are used to measure the reliability. These reliability measures are then associated with reliability factors included in the statistical multisource analysis. Experimental results are given for the application of statistical multisource analysis to multispectral scanner data where …
