On Directional Selectivity in Vertebrate Retina: An Experimental and Computational Study
(1992-01-01)
This thesis describes an investigation of retinal directional selectivity. We show intracellular (whole-cell patch) recordings in turtle retina which indicate that this computation occurs prior to the ganglion cell, ...
A Coupled Multi-ALU Processing Node for a Highly Parallel Computer
(1992-09-01)
This report describes Processor Coupling, a mechanism for controlling multiple ALUs on a single integrated circuit to exploit both instruction-level and inter-thread parallelism. A compiler statically schedules individual ...
Automated Program Recognition by Graph Parsing
(1992-07-01)
Recognizing standard computational structures (cliches) in a program can help an experienced programmer understand the program. We develop a graph parsing approach to automating program recognition in which programs ...
Reliable Interconnection Networks for Parallel Computers
(1991-10-01)
This technical report describes a new protocol, the Unique Token Protocol, for reliable message communication. This protocol eliminates the need for end-to-end acknowledgments and minimizes the communication effort ...
Probabilistic Analysis of Multistage Interconnection Network Performance
(1992-04-01)
We present methods of calculating the value of two performance parameters for multipath, multistage interconnection networks: the normalized throughput and the probability of successful message transmission. We develop ...
Temporal Surface Reconstruction
(1991-05-01)
This thesis investigates the problem of estimating the three-dimensional structure of a scene from a sequence of images. Structure information is recovered from images continuously using shading, motion or other visual ...
Multiple Mode Vibration Suppression in Controlled Flexible Systems
(1991-05-01)
Prior research has led to the development of input command shapers that can reduce residual vibration in single- or multiple-mode flexible systems. We present a method for the development of multiple-mode shapers which ...
MIT Scheme Reference Manual
(1991-01-01)
MIT Scheme is an implementation of the Scheme programming language that runs on many popular workstations. The MIT Scheme Reference Manual describes the special forms, procedures, and datatypes provided by the ...
Thread Scheduling Mechanisms for Multiple-Context Parallel Processors
(1995-06-01)
Scheduling tasks to efficiently use the available processor resources is crucial to minimizing the runtime of applications on shared-memory parallel processors. One factor that contributes to poor processor utilization ...
Enhanced Reality Visualization in a Surgical Environment
(1995-01-01)
Enhanced reality visualization is the process of enhancing an image by adding to it information which is not present in the original image. A wide variety of information can be added to an image ranging from hidden ...
