Non-Linear Dynamics And Control For Thermal Room Models, Milind Prabhakar Oak

Mechanical & Aerospace Engineering Theses & Dissertations

Heating, Ventilation and Air Conditioning (HVAC) building operations with emphasis on reduced energy costs and occupant comfort require a dynamic control of short response (minutes) elements of HVAC systems. Hence, it is imperative to acquire better methods of non-linear modeling for prescription of thermal controls which will regulate space conditions over wide parameter ranges without undue cycling or steady state errors. A first step towards this goal is identification and inclusion of short response dynamics elements in the HVAC systems model while retaining essential non-linearities. A single zone environmental chamber is modeled in the heating mode. In the model, …

Domain Decomposition For Multigrid, Finite Volume Flow Solvers, Victor Robert Lessard

Mechanical & Aerospace Engineering Theses & Dissertations

Computing the flow fields about three-dimensional complex configurations accurately becomes a difficult task, if it is attempted to generate a single, body fitted grid with proper clustering. The domain decomposition methods, which divide the computational domain into less complex subdomains, are extensively used to decrease the grid generation workload. A domain decomposition technique also allows the use of different solution methods for different subdomains. The objective of this work is to develop a domain decomposition method via overlapping/embedding the component grids, which is to be used by upwind, multigrid, finite volume solution algorithms. A computer code, given the name MaGGiE, …

Comparison Of Digital Controllers Used In Magnetic Suspension And Balance Systems, William Allen Kilgore

Mechanical & Aerospace Engineering Theses & Dissertations

Dynamic systems that were once controlled by analog circuits are now controlled by digital computers. Presented is a comparison of the digital controllers presently used with magnetic suspension and balance systems. The overall response of the systems are compared using a computer simulation of the magnetic suspension and balance system and the digital controllers. The comparisons include responses to both simulated force and position inputs. A preferred digital controller is determined from the simulated responses.

Study Of Loads On Four Box Culverts On The Alexandria - Ashland Highway, Bobby W. Meade, David L. Allen

Kentucky Transportation Center Research Report

Culverts on the Alexandria - Ashland Highway (AA Highway) were designed with modifications recommended in a 1984 report titled "Analysis of Loads and Settlements For Reinforced Concrete Culverts". In 1986, the Kentucky Department of Highways requested the Kentucky Transportation Center monitor selected culverts on the AA Highway. The objectives of this study were to compare predicted loads on the culverts to measured loads and to monitor differential settlement of the embankment near the culvert.

Four culverts with varied box dimensions and embankment heights were selected. Each of the four culverts was instrumented with earth pressure meters on the sidewalls and …

Evaluation Of Sorting Algorithm Performance On Single Instruction Multiple Data Machines, Dong Kuen Yang

Theses

Partitioning an application program into several tasks and executing them via parallel processing is one way to increase computation throughput and performance. But with a uniprocessor system, the performance increase will be minimal. Computer scientists have developed several multiprocessor systems to gain more speed in computation.

There are several computer architectures, such as pipeline machines, array processors and multiprocessor systems. They provide a parallel execution environment to increase the execution speed. But as the system becomes more complex, the communication traffic density between several processors increases more heavily. It has to provide some kind of control algorithm or routing function …

Adaptive Transform Coding Of Video With Motion Compensation And Vector Quantization, Jung-Hui Chien

Theses

This thesis proposes an efficient transform coding scheme for the low bit rate video sequence. The redundancy within adjacent video frame is exploited by motion compensated interframe prediction using the efficient independent orthogonal search technique, and the motion compensated frame difference (MCFD) signal is transform coding by 1-D DCT, 1-D HDCT and 2-D DCT, the coefficients are zonal masked, and vector quantizatied adaptively. The encoded MCFD as well as the motion information and variance grouping (side informations) are transmitted to the receiver to reconstruct the frame. The transform MCFD signal is classified into the four groups according to the coefficient …

Axon: Application-Oriented Lightweight Transport Protocol Design, James P.G. Sterbenz, Gurudatta M. Parulkar

All Computer Science and Engineering Research

This paper describes the application-oriented lightweight transport protocol for object transfer (ALTP-OT) in the Axon host communication architecture for distributed applications. The Axon Project is investigating an integrated design of host architecture, operating systems, and communication protocols to allow the utilization of the high band-width provided by the next generation of communication networks. ALTP-OT provides the end-to-end transport of segment and message objects for interprocess communication across a very high speed internetwork, supporting demanding applications such as scientific visualization and imaging. ALTP-OT uses rate-based flow control specifically oriented to the transfer of objects directly between application memory spaces. This document …

Axon: A High Speed Communication Architecture For Distributed Applications, James P.G. Sterbenz, Gurudatta M. Parulkar

All Computer Science and Engineering Research

There are two complementary trends in the computer and communication fields. Increasing processor power and memory availability allow more demanding applications, such as scientific visualization and imaging. Advances in network performance and functionality have the potential for supporting programs requiring high bandwidth and predictable performance. However, the bottleneck in increasingly in the host-network interface, and thus the ability to deliver high performance communication capability to applications has not kept up with the advances in computer and network speed. We have proposed a new architecture that meets these challenges called Axon, whose novel aspects include: an integrated design of hardware, operating …

Aerodynamic Forces On Flight Crew Helmets, Timothy A. Sestak, Richard M. Howard, Chester A. Heard

Publications

Wind tunnel tests were conducted to deter- mine the aerodynamic forces generated on aircrew flight helmets. Three helmets were tested: two used by aircrews flying ejection seat aircraft in the U.S. military, the Navy HGU-33/P and the Air Force HGU-53/P; and one prototype helmet of significantly different shape and volume. Axial and normal forces were measured through a range of pitch and yaw angles. It was found that large forces exist tending to promote helmet loss during ejection, and that simple modifications to the current helmet configurations can reduce those forces by as much as 40%. It is demonstrated that …

Efficient Interconnection Schemes For Vlsi And Parallel Computation, Ronald I. Greenberg

Computer Science: Faculty Publications and Other Works

This thesis is primarily concerned with two problems of interconnecting components in VLSI technologies. In the first case, the goal is to construct efficient interconnection networks for general-purpose parallel computers. The second problem is a more specialized problem in the design of VLSI chips, namely multilayer channel routing. In addition, a final part of this thesis provides lower bounds on the area required for VLSI implementations of finite-state machines. This thesis shows that networks based on Leiserson's fat-tree architecture are nearly as good as any network built in a comparable amount of physical space. It shows that these "universal" networks …

Effects Of N>M Clos Networks On Edge Coloring And Matrix Decomposition Algorithms, Ming-Hsing Lin

Theses

Considered in this thesis are n > m Clos networks on edge coloring and matrix decomposition algorithms. This work uses a two-fold approach to examine the effects of n > m Clos networks on edge coloring and matrix decomposition algorithms. First, edge coloring and matching on bipartite multigraphs are applied to routing on Clos networks. It is demonstrated that edge coloring algorithms which find a minimum edge coloring set up the routing for n > m Clos networks with redundancy. The results presented here indicate that the Euler coloring algorithm has applications on n > m Clos networks because it has fast time complexity …

Protocol Processing Delay Analysis On Ethernet By Simulation Of Njit Ethernet, Jagdish Gangrimal Rangwani

Theses

CSMA/CD based Local Area Networks account for about 75% of the installed LAN base today. As these networks are becoming available for high channel bandwidth, it is important to identify the bottlenecks in these networks. As channels are becoming high speed, bottleneck is shifting from channel to protocol processing. This delay depends on a particular implementation of the protocol and not the protocol standard itself.

This Thesis presents the analysis of delay on Ethernet. To achieve realistic results NJIT Ethernet, as it is configured, is modelled and simulated. Traffic on this network is measured and load on each segment is …

Optimization Of Throughput And Stability For Csma/Cd Channel, Liangshyng Jou

Theses

Multiple access technologies plays an important role in designing distributed computer communication system. Here, CSMA/CD has attracted researchers' attentions in the last ten years. In this paper, based on attributions of the slotted, nonpersistent CSMA/CD system, performance of CSMA/CD channel is analyzed. Adaptive Retransmission Technique is adopted to obtain the maximum throughput. Also, equilibrium contours are derived to discuss the stability of the system. And use FET to measure the stability of CSMA/CD channel that FET gives an approximate measure of the average uptime of an unstable channel.

On Implicational Dependency Families Possessing Finite Armstrong Relations, Kazem Taghva

Electrical & Computer Engineering Faculty Research

Let X ≠ 0 be a finite collection of nonempty relations over the relation scheme R(A1, A2 , ... , A,.); then the closure of X under embedding and direct product (up to isomorphism) is a finitely generated Implicational Dependency family (ID-family) generated by X. In this paper, we show that the class of finitely generated ID-families is identical to the class of those ID-families which possess a finite Armstrong relation.
