1 Poeppelmeier, Charles ChristianA boolean sum interpolation scheme to random data for computer aided geometric designThis thesis presents a new imterpolation function for randomly distributed data. The new interpolation function is capable of exactly reproducing quadratic surfaces. The new function is developed, through boolean sum theory, from Shepard's two dimensional interpolation functions and the Barnhill-Gre...Computer-aided geometric design; CAGD; Barnhill-Gregory; Interpolation functions1975
2 Brunvand, Erik L.; Smith, Kent F.A comparison of self-timed design using FPGA, CMOS, and GaAs technologiesAsynchronous or self-timed systems that do not rely on U global clock to keep system components synchronized can offer significant advantages over traditional clocked circuits in a variety of applications. One advantage is that because of the separation of timing, from, functionality in these sys...1992
3 Schott, Mathias; Hansen, Charles DA directional occlusion shading model for interactive direct volume renderingVolumetric rendering is widely used to examine 3D scalar fields Key aspect: provide perceptual cues to aid in understanding the data set Shading models with natural lighting conditions better convey depth information and spatial relationships Traditionally require considerable (pre)computatio...
4 Mecklenburg, RobertA dossier driven persistent objects facilityWe describe the design and implementation of a persistent object storage facility based on a dossier driven approach. Objects are characterized by dossiers which describe both their language defined and "extra-linguistic" properties. These dossiers are generated by a C+-f- preprocessor in concert ...Persistent object storage facility; Dossier driven1994
5 Evans, JohnA distributed object-oriented graphical programming systemThis report presents the design of a distributed parallel object system (DPOS) and its implementation using a graphical editing interface. DPOS brings together concepts of object-oriented programming and graphical programming with aspects of modern functional languages.

6 Evans, John; Kessler, Robert R.A communication-ordered task graph allocation algorithmThe inherently asynchronous nature of the data flow computation model allows the exploitation of maximum parallelism in program execution?? While this computational model holds great promise several problems must be solved in order to achieve a high degree of program performance?? The allocation...Data flow computation model1992
7 Zhang, LixinA DRAM backend for the impulse memory systemThe Impulse Adaptable Memory System exposes DRAM access patterns not seen in conventional memory systems. For instance, it can generate 32 DRAM accesses each of which requests a four-byte word in 32 cycles. Conventional DRAM backends are optimized for accesses that request full cache lines. They m...Impulse Adaptable Memory System; DRAM1998-12-16
8 Gopalakrishnan, GaneshA compositional model for synchronous VLSI systemsCurrently available hardware specification languages have two serious deficiencies: (i) inadequate protocol definition capabilities; (ii) lack of a compositional model. We now explain these in more detail.Very large scale integration; VLSI systems1987
9 Brunvand, Erik L.A cell set for self-timed design using actel FPGAsAsynchronous or self-timed systems that do not rely on a global clock to keep system components synchronized can offer significant advantages over traditional clocked circuits in a variety of applications. However, these systems require that suitable self-timed circuit primitives are available for b...Self-timed systems; Actel field programmable gate arrays; FPGA1991
10 Brunvand, Erik L.A comparison of modular self-timed design stylesState-machine sequencing methods in modular 2-phase and 4-phase asynchronous handshake control are compared. Design styles are discussed, and the sequencers are tested against each other using a medium-scale minicomputer test design implemented in FPGAs. Seven 4-phase sequencers are tested. In these...Self-timed; State-machine sequencing; Asynchronous handshake control1995

While this computational model holds great promise, several problems must be solved in order to achieve a high degree of program performance. The allocation and ...Task graph allocation algorithm1992
12 Davis, Alan L.A characterization of parallel systemsa taxonomy for parallel processing systems is presented which has some advantages over previous taxonomies. The taxonomy characterizes parallel processing systems using four parameters: topology, communication, granularity, and operation. These parameters and used repetitively in a hierarchical fash...Parallel systems1980
13 Carter, JohnA collective approach to harness idle resourcesWe propose a collective approach for harnessing the idle resources (cpu, storage, and bandwidth) of nodes (e.g., home desktops) distributed across the Internet. Instead of a purely peer-to-peer (P2P) approach, we organize participating nodes to act collectively using collective managers (CMs). Pa...Idle resources; Computer nodes2008
14 Sobh, Tarek M.A dynamic framework for intelligent inspectionCAD (Computer Aided Design) typically involves the design, manufacture and inspection of a mechanical part. The problem of reverse engineering is to take an existing mechanical part as the point of departure and to inspect or produce a design, and perhaps a manufacturing process, for the part. We pr...CAD; Discrete event dynamic systems; DEDS1992
15 Mathew, Binu K.; Davis, AlA characterization of visual feature recognitionNatural human interfaces are a key to realizing the dream of ubiquitous computing. This implies that embedded systems must be capable of sophisticated perception tasks. This paper analyzes the nature of a visual feature recognition workload. Visual feature recognition is a key component of a numb...Visual feature recognition; Human interfaces2003-09-03
16 Bhanu, Bir3-D model building for computer visionThis paper presents a Computer-Aided Geometric Design (CAGD) based approach for building 3-D models which can be used for the recognition of 3-D objects for industrial machine vision applications.

17 Carter, John B.A comparison of software and hardware synchronization mechanisms for distributed shared memory multiprocessorsEfficient synchronization is an essential component of parallel computing. The designers of traditional multiprocessors have included hardware support only for simple operations such as compare-and-swap and load-linked/store-conditional, while high level synchronization primitives such as locks, bar...Hardware locks1996
18 Zhang, LixinA comparison of online superpage promotion mechanismsThe amount of data that a typical translation lookaside buffer (TLB) can map has not kept pace with the growth in cache sizes and application footprints. As a result, the cost of handling TLB misses limits the performance of an increasing number of applications. The use of superpages, multiple adjac...Superpages; Translation lookaside buffer; TLB1999
19 McDirmid, Sean; Eide, Eric Norman; Hsieh, Wilson C.A comparison of Jiazzi and AspectJ for feature-wise decompositionFeature-wise decomposition is an important approach to building configurable software systems. Although there has been research on the usefulness of particular tools for featurewise decomposition, there are not many informative comparisons on the relative effectiveness of different tools. In this...Jiazzi; AspectJ; Feature-wise decomposition2004-03-23
20 A distributed garbage collection algorithmConcurrent Scheme extends the Scheme programming language, providing parallel program execution on a distributed network.

21 Barsky, Brian A.A description of several tools for the synchronization of concurrent processesConcurrent processes are tasks which may be executed simultaneously. When several such processes have access to shared variables, it is necessary to establish some regimen to control this access.
