Design of Cooperative Networks
(MIT Artificial Intelligence Laboratory, 1983-07)
In this paper we analyse several approaches to the design of Cooperative Algorithms for solving a general problem: That of computing the values of some property over a spatial domain, when these values are constrained (but ...
Representing Change for Common-Sense Physical Reasoning
(MIT Artificial Intelligence Laboratory, 1983-01)
Change pervades every moment of our lives. Much of our success in dealing with a constantly changing world is based in common-sense physical reasoning about processes and physical systems. Processes are the way quantities ...
Virtual Inclusion
(MIT Artificial Intelligence Laboratory, 1983-09)
Several recent knowledge-representation schemes have used virtual copies for storage efficiency. Virtual copes are confusing. In the course of trying to understand, implement, and use Jon Doyle's SDL virtual copy mechanism, ...
Differential Operators for Edge Detection
(MIT Artificial Intelligence Laboratory, 1983-03)
We present several results characterizing two differential operators used for edge detection: the Laplacian and the second directional derivative along the gradient. In particular, (a)we give conditions for coincidence of ...
CL1 Manual
(MIT Artificial Intelligence Laboratory, 1983-09)
CL1 is a prototyping language for programming a Connection Machine. It supports a model of the Connection Machine as a collection of tiny conventional machines (process elements), each with its own independent program counter.
Shear strength of reinforced concrete wall-beam structures: upper- bound analysis and experiments
(University of CambridgeDowning CollegeDepartment of Engineering, 1987-10-27)
This study presents rigid-plastic methods of analysis of shear failure in reinforced
concrete (R. C.) wall-beam type structures when subjected to in-plane loading. The
upper-bound approach is emphasised. Present shear ...
The elastic and plastic behaviour of cellular materials
(University of CambridgeChurchill CollegeDepartment of Engineering, 1981-11-10)
Cellular materials are widespread. Some, like wood and bone, occur in nature, while others, like polymeric foams, are manmade. Because of their cellular structure, they have unusual mechanical properties: they can be stiff, ...
Friction and lubrication in metal rolling
(University of CambridgeJesus CollegeDepartment of Engineering, 1989-11-14)
This dissertation is concerned with the physical processes which determine friction and
lubrication in metal rolling in the mixed lubrication regime, with particular attention paid to the conditions encountered when rolling ...
Scale effects in tests on footings
(University of CambridgeChrist's College, 1988-02-21)
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 ...
Radial basis function methods for multivariable approximation
(University of CambridgeDepartment of Applied Mathematics & Theoretical Physics, 1988-11-15)
