51 Computer-Aided Geometric Design Based Three-Dimensional Object Representations For Computer VisionModel-based recognition is one of the key paradigms in the field of computer vision and pattern recognition. However, at present there is an absence of a systematic approach to build vision models for a large class of three-dimensional (3-D) objects used in industrial environments. Computer-Aided Ge...computer vision; model based recognition; pattern recognition1988-12
52 Concurrent scheme, a language for concurrent symbolic computingThis research addresses a portion of the "software problem," by proposing language constructs to extend the Lisp class of computer language commonly used for symbolic computing. As a representative of the class of Lisp-like languages, the Scheme dialect will be used throughout this research.computer language; symbolic computing; concurrent processing1991-05
53 Considerations for the Development of a Computer-Aided Electrical Design SystemThe specifications of a computer-aided design system are proposed based on the implementation of a prototype subsystem using UNIVAC 1108 and PDP-8 computers. The design system would aid a designer who wished to select and specify electrical fixtures, controls and circuits, and place them in a buildi...1969-09
54 Consistent Geometric Modeling ApproachesBoolean set operations are important in solid modeling; however making them robust is problematic. This thesis summarizes the problems with robustness of geometric algorithms caused by approximated data and numerical computation and provides two different approaches to build a robust geometric model...geometric model; boolean set; adaptive single tolerance1993
55 Constraint driven synthesis of hardware designDesign synthesis (or Synthetic Design) is an attractive alternative to manual design, due to the obvious benefits of decreased development time and correctness by construction. Unfortunately, the price for this automation has frequently been inefficient designs and a narrow range of application. The...design synthesis; constraint driven synthesis; constraints; computers1983-08

58 Data structures and system support for a graphical programming language editing and program development environmentThis thesis presents an editing tool for use in the development of data-driven style programs. These programs are based on a hierarchical graphical syntax rather than the conventional textual syntax. The editor provides the programmer with all the necessary operations for traversing and manipulating...editing tool; computers; data-driven style programs1983-12
59 Design and implementation of a portable shared memory serverProcesses communicate between one another using mechanisms like message passing, files, shared memory, etc. In current systems, shared memory is not commonly used even though it has many advantages over message passing and file sharing such as simplicity, efficiency, and lower space overhead. This t...memory management; portable shared memory server1994-12
60 The design and implementation of an OR-parallel logic programming systemThe research focus in OR-parallel logic programming is shifting rapidly from theoretical considerations and simulation on uniprocessors to implementation on true multiprocessors. This dissertation describes the design and implementation of such a system or OR-parallel Horn clause logic programs on t...OR-parallel; computers1987-08
61 Design for a micromodular self-timed system, AAbstract: Self-timed systems lend themselves readily to interactive design and implementation of concurrency. These systems and their properties are discussed, and the implementation for a micromodular system is described. The use of formal techniques to design asynchronous machines with concurrency...Switching systems; micromodular representations; self-timed systems; interactive design; concurrency1972-03
62 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.
