Chemical Percolation Model For Devolatilization: Ii. Temperature And Heating Rate Effects On Product Yields, Thomas H. Fletcher, Alan R. Kerstein, Ronald J. Pugmire, David M. Grant

Faculty Publications

The chemical percolation devolatilization (CPD) model describes the devolatilization behavior of rapidly heated coal based on the chemical structure of the parent coal. Percolation lattice statistics are employed to describe the generation of tar precursors of finite size based on the number of cleaved labile bonds in the infinite lattice. The chemical percolation devolatilization model described here includes treatment of vapor-liquid equilibrium and a cross-linking mechanism. The cross-linking mechanism permits reattachment of metaplast to the infinite char matrix. A generalized vapor pressure correlation for high molecular weight hydrocarbons, such as coal tar, is proposed based on data from coal liquids. …

Chemical Structure Of Char In The Transition From Devolatilization To Combustion, Thomas H. Fletcher, Mark S. Solum, David M. Grant, Ronald J. Pugmire

Faculty Publications

Coal devolatilization experiments are generally conducted separately from char oxidation experiments, and the relationship between the chars generated in the two types of research is often ignored. However, char is one of the most important products of coal devolatilization and must be characterized as a function of temperature and heating rate in a manner similar to that for gaseous devolatilization products. The chemical structure of the parent coal directly affects devolatilization behavior. In this work, the chemical structure of chars from five coals of different rank are examined, and implications on char reactivity are discussed. Chars were obtained as a …

Fault-Tolerant Concurrent Branch And Bound Algorithms Derived From Program Verification, Hanan Lutfiyya, Aggie Sun, Bruce M. Mcmillin

Computer Science Faculty Research & Creative Works

An important aspect which is often overlooked in software design of distributed environments is that of fault tolerance. Many methodologies in the past have attempted to provide fault tolerance efficiently but have never been successful at eliminating explicit time and space redundancy. One approach for providing fault tolerance is through examining the behavior and properties of the application and deriving executable assertions that detect faults. Our work focuses on transforming the assertions of a verification proof of a program to executable assertions. These executable assertions may be embedded in the program to create a fault-tolerant program. It is also shown …

Composite Stock Cutting Through Simulated Annealing, Hanan Lutfiyya, Bruce M. Mcmillin, Pipatpong Poshyanonda, Cihan H. Dagli

Computer Science Faculty Research & Creative Works

This paper explores the use of Simulated Annealing as an optimization technique for the problem of Composite Material Stock Cutting. The shapes are not constrained to be convex polygons or even regular shapes. However, due to the composite nature of the material, the orientation of the shapes on the stock is restricted. For placements of various shapes, we show how to determine a cost function, annealing parameters and performance. © 1992.

Formation Of Clusters And Resolution Of Ordinal Attributes In Id3 Classification Trees, Chaman Sabharwal, Keith R. Hacke, Daniel C. St. Clair

Computer Science Faculty Research & Creative Works

Many learning systems have been designed to construct classification trees from a set of training examples. One of the most widely used approaches for constructing decision trees is the ID3 algorithm [Quinlan 1986]. Decision trees are ill-suited to handle attributes with ordinal values. Problems arise when a node representing an ordinal attribute has a branch for each value of the ordinal attribute in the training set. This is generally infeasible when the set of ordinal values is very large. Past approaches have sought to cluster large sets of ordinal values before the classification tree is constructed [Quinlan 1986; Lebowitz 1985; …

Craft Specialization And Exchange Among The Virgin Anasazi, James R. Allison

Faculty Publications

A large proportion of the culinary ceramics found on 11th century Anasazi sites in the Moapa Valley of Nevada were manufactured more that fifty miles to the east, in northwestern Arizona. This paper uses analyses of ceramics from sites in southeastern Nevada, northwestern Arizona, and southwestern Utah to more precisely define the regional distribution of these ceramics and to assess their degree of standardization in form and technology. Questions relating to the development of community specialization and interaction in egalitarian societies are--examined in light of these analyses.

An Optical Adaptive Resonance Neural Network Utilizing Phase Conjugation, Donald C. Wunsch, D. J. Morris, T. P. Caudell, R. A. Falk

Electrical and Computer Engineering Faculty Research & Creative Works

An adaptive resonance (ART) device has been conceived that is fully optical in the input-output processing path. It is based on holographic information processing in a phase-conjugating crystal. This sets up an associative pattern retrieval in a resonating loop utilizing angle-multiplexed reference beams for pattern classification. A reset mechanism is used to reject any given beam, allowing an ART search strategy. The design is similar to an existing nonlearning optical associative memory, but it does allow learning and makes use of information the other device discards. This device is expected to offer higher information storage density than alternative ART implementations.

Error Patterns In Research Papers By Pacific Kim Students, Chris Crowe

Faculty Publications

By looking for patterns of errors in the research papers of Asian students, educators can uncover pedagogical strategies to help students avoid repeating such errors. While a good deal of research has identified a number of sentence-level problems which are typical of Asian students writing in English, little attempt has been made to consider the specific problems which a long research paper presents. Of these problems, Asian students have the most difficulty integrating sources from research and developing transition, unity, and cohesion. These problems stem not necessarily from different thought patterns or primary language interference, but from the challenge of …

Optimal Response To Periodic Shortage: Engineering/Economic Analysis For A Large Urban Water District, Anthony Fisher, David Fullerton, Nile Hatch, Peter Reinelt

Faculty Publications

The problem addressed by this study is how a large urban water district can best respond to a drought or the prospect of a drought. Specifically, what is the least cost combination of alternatives to meet periodic shortages? A solution to this problem may involve structural approaches (such as developing new local storage capacity), a mix of structural and nonstructural (such as conjunctive use combined with water exchanges or sales), or purely nonstructural approaches (such as changes in water pricing). The application is to the East Bay Municipal Utility District (EBMUD), which includes portions of Alameda and Contra Costa counties …

Semi-Supervised Adaptive Resonance Theory (Smart2), Christopher J. Merz, William E. Bond, Daniel C. St. Clair

Computer Science Faculty Research & Creative Works

Adaptive resonance theory (ART) algorithms represent a class of neural network architectures which self-organize stable recognition categories in response to arbitrary sequences of input patterns. The authors discuss incorporation of supervision into one of these architectures, ART2. Results of numerical experiments indicate that this new semi-supervised version of ART2 (SMART2) outperformed ART for classification problems. The results and analysis of runs on several data sets by SMART2, ART2, and backpropagation are analyzed. The test accuracy of SMART2 was similar to that of backpropagation. However, SMART2 network structures are easier to interpret than the corresponding structures produced by backpropagation.

Fast Power Flow With Capability Of Corrective Control Using A Neural Network, Badrul H. Chowdhury, B. M. Wilamowski

Electrical and Computer Engineering Faculty Research & Creative Works

The authors present a number of different configurations of a neural network and identify a particular case which is most suitable for power flow analysis in real-time applications. The advantage of fast computation of the artificial neural network (ANN) is used for obtaining power flow solutions in real time. The inputs to the ANN are the real and reactive power generating and demand in the system, and the output data are the complex bus voltages. A few configurations of the neural network were experimented with, and the best results were achieved with a single-layer feedforward neural network with nonlinear feedback. …

Hybrid Clamping In Ntsc Digital Video Equipment, Norman R. Cox, Douglas William Irwin

Electrical and Computer Engineering Faculty Research & Creative Works

Two algorithms that are suitable for deriving the blanking level of a National Television Systems Committee (NTSC) composite video signal are described. One method consists of averaging digitized color-burst samples taken from successive scan lines. A second method involves processing a group of samples taken from a single burst interval. Either algorithm used in a hybrid clamping arrangement results in automatic drift compensation and the ability to tie the back porch or sync tip to a predetermined digital output code. This aids in matching the analog signal to the input of the analog-to-signal (A/D) converter for maximum signal-to-noise ratio (SNR). …

“Names, Hypocoristic,” In Anchor Bible Dictionary, Dana M. Pike

Faculty Publications

A hypocoristicon is generally a single-element name resulting from the shortening of an originally longer one. Hebrew names and Semitic names in general, were often composed of two elements (or, as was often the case in Akkadian names and sometimes the case with West Semitic ones, three elements) which formed a nominal or verbal sentence.

Transition From Laminar To Turbulent Flow Around An Airfoil, Chang-Ren Chen

Doctoral Dissertations

"A computational fluid dynamics (CFD) code has been developed for two-dimensional incompressible turbulent flows and employed to solve the Navier Stokes equations around an airfoil of arbitrary shape. A low-Reynolds-number k — e turbulence model including curvature effect was used to consider the gain and loss of turbulent kinetic energy. To include laminar sublayer into the computational domain, a multi-layer grid and a cubic-slpine grid were introduced through a conservative form of coordinate transformation. The flow structure varies with the Reynolds numbers. For an airfoil at low Reynolds numbers (below ten thousand), distinct vortex shedding patterns can be found in …

The Error Probability Of Reed-Solomon Coding And Interleaving On A Bursty-Noise Channel, W. J. Ebel, William H. Tranter

Electrical and Computer Engineering Faculty Research & Creative Works

A useful bursty-noise channel model is proposed and, using this model, a binary communication system using Reed-Solomon coding and interleaving is analyzed. The model includes both thermal noise, which gives rise to random errors, and burst noise, which gives rise to error bursts. Error probabilities are derived for the uncoded system, and error probability bounds are derived for the coded system. Monte Carlo simulation results agree well with theory.

A Methodology For Customer Requirements Generation In Communication Systems Planning, Negaa Albegami, Yildirim Omurtag

Engineering Management and Systems Engineering Faculty Research & Creative Works

In electronic communication systems it is nearly impossible to keep up with changing technology. This problem is further aggregated in the developing countries where the contractor (probably a western company) is expected to develop the system from the ground up. A basic problem which confronts this approach is either: 1) The customer will start adding or rejecting some of the capabilities, or 2) The local operation will never use some of the capabilities. Both of these outcomes are costly in terms of time and resources available to a developing country. This paper describes a new methodology for requirements generation to …

Two Dimensional Nesting Problem: Artificial Neural Network And Optimization Approach, Pipatpong Poshyanonda, Cihan H. Dagli, Ali Bahrami

Engineering Management and Systems Engineering Faculty Research & Creative Works

An approach that integrates artificial neural networks and optimization methods for automating regularly-shaped pattern generation processes is proposed. In the proposed approach the artificial neural network model is used for generating rectangular pattern configurations with an acceptable scrap. Rectangular patterns of different sizes are used as the input of the neural network to generate location and rotation of each pattern when they are combined. The pattern configurations generated through the neural network are represented as decision variables of a mathematical programming model for determining an efficient nesting of different sizes of rectangular patterns for meeting the demand of a given …
