ADA Tasking Facilities for Concurrent and Real-Time Programming

Description: This paper describes multitasking facilities of Ada in concurrent and real-time programming. Synchronization and process communication mechanisms are discussed in detail, also, a new mechanism to solve the scheduling problem is developed. In the concurrent programming aspect, a comparison is made between Ada's rendezvous and Pascal's Monitor concept. In the real-time programming aspect, the differences between the Ada multitasking and the traditional "cyclic executive approaches are contrasted … more

Computer Analysis of Amino Acid Chromatography

Description: The problem with which this research was done was that of applying the IBM360 computer to the analysis of waveforms from a Beckman model 120C liquid chromatograph. Software to interpret these waveforms was written in the PLl language. For a control run, input to the computer consisted of a digital tape containing the raw results of the chromatograph run. Output consisted of several graphs and charts giving the results of the analysis. In addition, punched output was provided which gave the name… more

Computerized Analysis of Radiograph Images of Embedded Objects as Applied to Bone Location and Mineral Content Measurement

Description: This investigation dealt with locating and measuring x-ray absorption of radiographic images. The methods developed provide a fast, accurate, minicomputer control, for analysis of embedded objects. A PDP/8 computer system was interfaced with a Joyce Loebl 3CS Microdensitometer and a Leeds & Northrup Recorder. Proposed algorithms for bone location and data smoothing work on a twelve-bit minicomputer. Designs of a software control program and operational procedure are presented. The filter made w… more

Design and Implementation of a Parser for the DBase II Query Language

Description: In this paper the DBase II query language of an RDBMS for personal computers is discussed. Other languages will be provided by large and sophisticated DBMS will not be discussed here. The reason for selecting the DBase II query language for discussion are as follows: 1. It is a simple language that can be learned easily [TOWN 84, DINE 84]. Within a short period, users can learn all of the facilities and manage the system very well. 2. It is a language suitable for interactive programming and ex… more

Design and Implementation of a PDP-8 Computer Assembler Executing on the IBM 360/50 Computer

Description: This problem is intended to be an introduction to the design of a software system which translates PDP-8 assembly language source into it's machine-readable object code. This assembler runs on the IBM 360/50. It is assumed that the reader is familiar with the basic PDP-8 assembly language. For the description and use of this assembler the reader is referred to the PAL-III SYMBOLIC ASSEMBLER PROGRAMMING MANUAL from DEC (order number DIGITAL 8-3-5, Digital Equipment Corporation: Maynard, Massachu… more

Development of a Text Formatted Under VAX/VMS Operating System

Description: No matter how extended the use of the computer is, the printed document is still the primary medium for the presentation information, and will continue to be for some time. The use of computing facilities for preparation and production of the document is becoming as prevalent as their use for numeric computation. Commercially, document preparation systems are now a standard facility at research institution, and they have become quite common on each computer program. A conventional document prep… more

An Efficient Hybrid Heuristic and Probabilistic Model for the Gate Matrix Layout Problem in VLSI Design

Description: In this thesis, the gate matrix layout problem in VLSI design is considered where the goal is to minimize the number of tracks required to layout a given circuit and a taxonomy of approaches to its solution is presented. An efficient hybrid heuristic is also proposed for this combinatorial optimization problem, which is based on the combination of probabilistic hill-climbing technique and greedy method. This heuristic is tested experimentally with respect to four existing algorithms. As test ca… more

An English and Arabic Character Printer

Description: This paper is presented in satisfaction of the requirement for two problems in lieu of thesis which are required for the degree, Master of Science. The two problems are: (1) to provide an electric interface between the M6800 microprocessor and the printer; and (2) to design an Arabic character set and to provide the logic required for its implementation. As it would be artificial and impractical to document these problems separately, a single document here is provided.

An Implementation of the IEEE Standard for Binary Floating-Point Arithmetic for the Motorola 6809 Microprocessor

Description: This thesis describes a software implementation of the IEEE Floating-Point Standard (IEEE Task P754), which is believed to be an effective system for reliable, accurate computer arithmetic. The standard is implemented as a set of procedures written in Motorola 6809 assembly language. Source listings of the procedures are contained in appendices.

Improving Digital Circuit Simulation: A Knowledge-Based Approach

Description: This project focuses on a prototype system architecture which integrates features of an event-driven gate-level simulator and features of the multiple expert system architecture, HEARSAY-II. Combining artificial intelligence and simulation techniques, a knowledge-based simulator was designed and constructed to model non-standard circuit behavior. This non-standard circuit behavior is amplified by advances in integrated circuit technology. Currently available digital circuit simulators can not s… more

Linearly Ordered Concurrent Data Structures on Hypercubes

Description: This thesis presents a simple method for the concurrent manipulation of linearly ordered data structures on hypercubes. The method is based on the existence of a pruned binomial search tree rooted at any arbitrary node of the binary hypercube. The tree spans any arbitrary sequence of n consecutive nodes containing the root, using a fan-out of at most [log₂ 𝑛] and a depth of [log₂ 𝑛] +1. Search trees spanning non-overlapping processor lists are formed using only local information, and can be use… more

Quality-of-Service Provisioning and Resource Reservation Mechanisms for Mobile Wireless Networks

Description: In this thesis, a framework for Quality of Service provisioning in next generation wireless access networks is proposed. The framework aims at providing a differentiated service treatment to real-time (delay-sensitive) and non-real-time (delay-tolerant) multimedia traffic flows at the link layer. Novel techniques such as bandwidth compaction, channel reservation, and channel degradation are proposed. Using these techniques, we develop a call admission control algorithm and a call control block … more

The Telecommunications Network Configuration Optimization Problem

Description: The purpose of telecommunication network configuration optimization is to find the best homing relationship between tandems and switches so as to minimize interswitch traffic, or equivalently to maximize intraswitch traffic. Note that, since minimal interswitch traffic implies minimal IMT utilization, communication costs will also be minimal.
