26 First-order preference theories and their applicationsThis dissertation begins with a logical analysis of the notion of preference. Earlier approaches to logical analysis of preference are surveyed and their shortcomings pointed out. Next, a family of modal logics of preference is presented with soundness and completeness results for both the propositi...1992-12
27 A priori digital speech analysisAbstract: This paper describes a priori digital speech analysis. This method takes advantage of the quasi-periodic nature of voice speech sounds to reduce the amount of computation needed to obtain the analysis parameters. The vocal tract is modeled as an all-pole digital filter (predictive coding)...speech analysis; predictor coefficients; pitch period1973-03
28 Design goals of an editor for storage logic arraysAbstract: Integrated circuits of increased density require both better fabrication technology and tools for managing the design complexity. Before stepping firmly into the era of Very Large Scale Integration (VLSI), powerful abstractions of integrated circuit design and associated software tools mu...storage logic arrays; Integrated circuit design1981-06
29 Implementation of a network database using a function graph languageAbstract: Most of the work on databases to date has involved approaches that deviate considerably from a purely mathematical (functional) viewpoint. The research reported in this thesis deals with an implementation of a network database using FGL to achieve this functionality. The amount of database...network database1981-06
30 Image Recognition Using Generalized CorrelationThis paper investigates the use of generalized cross-correlation in pattern matching when the objects may be of one or two dimensions. Generalized correlation can be used to determine the amount of dilatation and rotation between a given template and an object, in addition to determining the relativ...1977-08
31 A FORTRAN V Interactive Graphical SystemThe system described provides the capability of transforming an ordinary FORTRAN 5 program into a highly interactive program. The converted program makes the user, the display scope, and teletype console all an integral part of the execution of the program. At present, the system allows the user to ...1968-04-03
32 Performance Directed SimulationThe overall scientific objective of this research was to develop techniques for speeding up discrete event simulation (DES) programs in applications such as simulation of computer architectures, communication networks, battlefield scenarios, etc. Such simulations often require prohibitive amounts of...1989-01-26
33 Feature-based reverse engineering of mechanical parts: revisionReverse engineering of mechanical parts requires extraction of information about an instance of a particular part sufficient to replicate the part using appropriate manufacturing techniques. This is important in a wide variety of situations, since functional CAD models are often unavailable or unusa...1995-11-06
34 A Dynamic Model for Computer-Aided ChoreographyThe application of the digital computer in the field of dance choreography is a relatively unexplored area. The use of the computer in other arts is more widely known. The report describes an interactive, FORTRAN 5 UNIVAC 1108 computer which relates the angular movements of the joints of the display...1970-06
35 Discrete B-Splines as an Approach to Computer Aided Geometric DesignInvestigations have been made of many interesting problems deriving from the applications of discrete splines to the problems of computer aided geometric design. New theory and algorithms have been developed and support mechanisms based on the Oslo algorithm have been incorporated in order to help u...1985-09
36 Surface Representation-Symbolic ComputationRecent research in Computer Aided Geometric Design is surveyed in this paper. A DEMONSTRATION of the feasibility and utility of some of the new methods of curve and surface representation for interactive design is given in a movie which will be shown during the presentation. (Author)1978-04
37 A Java-based active network operating system (JANOS)The JANOS prqjects' primary objective was to develop a principle local operating system for active network nodes. The operating system is oriented toward executing untrusted Java bytecode, primarily for management and control.,The original document contains color images.2003-11
38 Noise Suppression Methods for Robust Speech ProcessingRobust speech processing in practical operating environments requires effective environmental and processor noise suppression. This report describes the technical findings and accomplishments to develop real time, compressed speech analysis-synthesis algorithms whose performance is invariant under s...1979-04
39 Look ahead in Parallel Discrete Event SimulationEmpirical performance evaluations of parallel, discrete event simulation algorithms using deadlock avoidance and deadlock detection and recovery techniques developed by Chandy and Misra have been performed using the BBN Butterfly multiprocessor. Experiments using synthetic workloads reveal that the ...1988-08
40 Interactive Spline ModellingThis contract has initiated explorations into the advantages of interactive environments for developing computer based spline representations and the types of moderately complex objects for which it might be suitable. Additionally mathematical tools for surface fitting and modification in an interac...1983-04-27
41 An Interactive Continuous Simulation LanguageComputer simulation has come into increasingly widespread use to study the behavior of systems of which the state of the system changes over time. There have been two main types of simulation languages developed to study these systems, continuous simulation languages to study continuous change model...1968-10
42 An Analytical Approach to Computer Systems SchedulingThe report examines some aspects of the problem of allocating resources in a multi-programmed computer system. It first investigates to what extent the users might participate in resource allocation decisions; a system that dynamically determines the prices of services is advocated. A model is studi...1970-06
43 Syntax Directed on-Line Recognition of Cursive WritingA syntax organization for recognition of handwritten connected-word is studied in the work. Each writing is cut into strokes at the middle point of every down cave of the writing, and the strokes are named using their directional characteristics and relative size among the strokes. A syntax is organ...1968-07
44 A Multiprocessor Implementation of CSP (Communicating Sequential Processes)Communicating Sequential Processes (CSP) is a well known paradigm for communication and synchronization of a parallel computation. A CSP program consists of a collection of processes P(1), P(2),....., P(N) that interact by exchanging message. These message passing primitives, called input and output...1988-03
45 Three-Dimensional Input for Computer GraphicsThe paper states the need for three-dimensional input for architectural work using computer graphics. The paper consists of two sections. The first section deals with laser Examples are given comparing old methods of ground survey with photogrammetry.1968-06
46 HOP: (Hardware Viewed as Objects and Processes). A Process Model for Synchronous Hardware SystemsA new Hardware Specification Language (HSL) called HOP is presented. HOP stands for Hardware viewed as Objects and Processes. It can be used for specifying the structure, behavior, and timing of digital systems. HOP was designed for several reasons. It integrates well-tested ideas from past work tha...1988
