The bypass paths and multiported register files in microprocessors serve as an implicit interconnect tocommunicate operand values among pipeline stages and multiple ALUs. Previous superscalar designs implementedthis ...

We are investigating vector-thread architectures which provide competitive performance and efficiency across a broad class of application domains. Vector-thread architectures unify data-level, thread-level, and instruction-level ...

This dissertation presents an investigation of the effects of stress, and of absolute and relative particle size, in tests on vertically loaded footings. Two granular materials, namely, a silica rock flour and a Chatelet ...

Oscillatory Flow Mixing is a recent development in mixing technology which has evolved over the past decade. It has a number of similarities to other mixing technologies, particularly pulsed and reciprocating plate ...

We characterize some properties of the zero-crossings of the laplacian of signals - in particular images - filtered with linear filters, as a function of the scale of the filter (following recent work by A. Witkin, 1983). ...

We use a three-bead-spring model to investigate the dynamics of bi-flagellate micro-swimmers near a surface. While the primary dynamics and scattering are governed by geometric-dependent direct contact, the fluid flows ...

Internal gravity waves play a fundamental role in the dynamics of stably stratified regions of the atmosphere and ocean. In addition to the radiation of momentum and energy remote from generation sites, internal waves ...

The purpose of this short document is to exhibit how a HACKER-like top-down planning and debugging system can be applied to the problem of the design and debugging of simple analog electronic circuits. I believe, and I ...

We present a biologically motivated method for scene image classification. The core of the method is to use shape based image property that is provided by a hierarchical feedforward model of the visual cortex [18]. Edge ...

Peer-to-peer or P2P systems are applications that allow a network of peers to share resources in a scalable and efficient manner. My research is concerned with the use of P2P systems for sharing databases. To allow data ...

In dealing with long-term tracking databases withwide-area coverage, an important problem is in formulating anintuitive and fast query system for analysis. In such a querysystem, a user who is not a computer vision research ...

I describe the design and implementation plans for a computer that is optimized as a microcoded interpreter for Scheme. The computer executes SCode, a typed-pointer representation. The memory system has low-latency as ...

We have designed and implemented a single-chip microcomputer (which we call SCHEME-79) which directly interprets a typed pointer variant of SCHEME, a dialect of the language LISP. To support this interpreter the chip ...

Scheme86 is a computer system designed to interpret programs written in the Scheme dialect of Lisp. A specialized architecture, coupled with new techniques for optimizing register management in the interpreter, allows ...

Inspired by ACTORS [Greif and Hewitt] [Smith and Hewitt], we have implemented an interpreter for a LISP-like language, SCHEME, based on the lambda calculus [Church], but extended for side effects, multiprocessing, and ...

Scientific communnities have proven to be extremely successful at solving problems. They are inherently parallel systems and their macroscopic nature makes them amenable to careful study. In this paper the character of ...

In this paper, we present the design of Scoop, a system for indexing and querying stored data in sensor networks. Scoop works by collecting statistics about the rate of queries and distribution of sensor readings over a ...

This program will take a list of display instructions and cause it to be plotted. For further or more detailed information consult with Michael Speciner.

The screened Coulomb interaction between a pair of infinite parallel planes with spatially varying surface charge is considered in the limit of small electrical potentials for arbitrary Debye lengths. A simple expression ...

Many important geometric estimation problems naturally take the form of synchronization over the special Euclidean group: estimate the values of a set of unknown poses given noisy measurements of a subset of their pairwise ...
