In mobile robot research we believe the structure of the platform, its capabilities, the choice of sensors, their capabilities, and the choice of processors, both onboard and offboard, greatly constrains the direction of ...

Current approaches to generation for machine translation make use of direct-replacement templates, large grammars, and knowledge-based inferencing techniques. Not only are rules language-specific, but they are too ...

This paper introduces soft objects, a new paradigm for object oriented programming. This paradigm replaces the traditional notion of object classes with the specification of transforming procedures which transform ...

The intent of this research is to study the dynamic behavior of a solid body resting on a moving surface. Results of the study are then used to propose methods for controlling the orientation of parts in preparation ...

This paper examines the issues and the solutions that have been studied in database (DB) integration research and tries to draw lessons from them for knowledge base (KB) integration.

This paper describes a fully implemented computational architecture that controls the Utah-MIT dextrous hand and other complex robots. Robots like the Utah-MIT hand are characterized by large numbers of actuators and ...

Optical flow is the apparent (or perceived) motion of image brightness patterns arising from relative motion of objects and observer. Estimation of the optical flow requires the application of two kinds of constraint: ...

Biophysics of computation is a new field that attempts to characterize the role in information processing of the several biophysical mechanisms in neurons, synapses, and membranes that have been uncovered in recent ...

Integration of several vision modules is likely to be one of the keys to the power and robustness of the human visual system. The problem of integrating early vision cues is also emerging as a central problem in current ...

The benefits of programming in a functional style are well known. In particular, algorithms that are expressed as compositions of functions operating on series/vectors/streams of data elements are much easier to ...

The Voronoi diagram has proved to be a useful tool in a variety of contexts in computational geometry. Our interest here is in using the diagram to simplify the planning of collision-free paths for a robot among ...

The dynamicist's workbench is a system for automating some of the work of experimental dynamics. We describe a portion of our system that deals with the setting up and execution of numerical simulations. This part of ...

There has been a long-standing desire in computer science for a way of collecting and using libraries of standard software components. The limited success in actually doing this stems not from any resistance to the ...

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 ...

This paper describes several parallel algorithms that solve geometric problems. The algorithms are based on a vector model of computation---the scan-model. The purpose of this paper is both to show how the model can ...

Comparative analysis is the problem of predicting how a system will react to perturbations in its parameters, and why. For example, comparative analysis could be asked to explain why the period of an oscillating ...

The Phase Space is a powerful tool for representing and reasoning about the qualitative behavior of nonlinear dynamical systems. Significant physical phenomena of the dynamical system---periodicity, recurrence, stability ...

Essentially all program translators (both source-to-source translators and compilers) operate via transliteration and refinement. This approach is fundamentally limited in the quality of the output it can produce. In ...
