127 Transforming an Ada program unit to silicon and verifying its behavior in an Ada environment: a first experimentMicroelectronics technology has advanced so rapidly and been so successful that we are new having to build large systems with a multitude of diverse, interacting components. Some components of these systems exhibit distinct architectures and may, in fact, be implemented following different choices o...Transformation; Ada program units; Silicon1983
128 Some experiments with the 3-D hough shape transformThe application of the Hough shape transform to the problem of the identification and localization of objects in 3-space is presented. The rotation-invariant Hough transform is defined which permits the determination of the geometric transformation from the model to the detected object. Given a samp...Hough shape transform1983
129 FUNLOG = functions + logic: a computational model integrating logic programming and functional programming (Rev. May 1983)Funlog, a computational model which attempts to integrate functional programming and logic programming is described. The model supports computations with infinite data structures without the introduction of complex control issues at the user-level. Control characteristics are improved as compared wi...FUNLOG; Functional programming; Logic programming1983
130 A category theoretic formalism for abstract interpretationWe present a formal theory of abstract interpretation based on a new category theoretic formalism. This formalism allows one to derive a collecting semantics which preserves continuity of lifted functions and for which the lifting functon is itself continuous. The theory of abstract interpretation i...Formal theory; Theoretic formalism; Lifted functions1984
131 Computer aided designThe report is based on the proposal submitted to the National Science Foundation in September 1981, as part of the Coordinated Experimental Computer Science Research Program. The sections covering the budget and biographical data on the senior research personnel have not been included. Also, the sec...1984
132 Shape matching of two-dimensional objectsIn this paper we present results in the areas of shape matching of nonoccluded and occluded two-dimensional objects. Shape matching is viewed as a "segment matching" problem. Unlike the previous work, the technique is based on a stochastic labeling procedure which explicitly maximizes a criterion ...Shape matching; Two-dimensional objects; Segment matching1984
133 An experimental system for computer aided geometric designThe main goal of this proposed level-of-effort project is to extend present capabilities in the area of Computer Aided Geometric Design (CAGD) and to develop custom VLSI support for some special geometric functions.Computer aided geometric design; CAGD; VLSI; Very large scale integration1984
134 Abstract interpretation and indeterminacyWe present a semantic theory that allows us to discuss the semantics of indeterminate operators in a dataflow network. The assumption is made that the language in which the indeterminate operators are written has a construct that allows for the testing of availability of data on input lines. We then...Semantics; Indeterminate operators1984
135 Simulation of CellsA self-timed cell set and library for the design of integrated circuits is presented. The cell set and library are two different cellular methods of designing integrated circuits. These have been incorporated to form a hybrid system which exploits the advantages provided by each. The cell set an...Self-timed; Cell set1984
136 MKS: a multisensor kernel systemThe multisensor kernel system (MKS) is presented as a means for multisensor integration and data acquisition.

137 Logical sensor systemsMulti-sensor systems require a coherent and efficient treatment of the information provided by the various sensors. We propose a framework the Logical Sensor Specification System, in which the sensors can be abstractly defined in terms of computational processes operating on the output from other se...Logical sensor systems; Multi-sensor systems; Multisensor systems; Logical Sensor Specification System1984
138 Representation and shape matching of 3-D objectsA three-dimensional scene analysis system for the shape matching of real world 3-D objects is presented. Various issues related to representation and modeling of 3-D objects are addressed. A new method for the approximation of 3-D objects by a set of planar faces is discussed. The major advantage of...3-D objects; Representation; Shape matching; Scene analysis system1984
139 Semantics of networks containing indeterminate operatorsWe discuss a denotational semantics for networks containing indeterminate operators. Our approach is based on modelling a networks by the set of all its possible behaviors. Our notion of behavior is a sequence of computational actions. The primitive computational action is an event: the appearance o...1984
140 Implementing multi-sensor systems in a functional languageWe discuss a methodology for configuring systems of sensors using a functional language. To date no such general methodology exists, and existing multi-sensor systems have been hand-crafted around a particular application. Our main point is that the use of abstraction and of functional language fe...Multi-sensor systems; Multisensor systems1984
141 Range data processing: representation of surfaces by edgesRepresentation of surfaces by edges is an important and integral part of a robust 3-D model based recognition scheme. Edges in a range image describe the intrinsic characteristics about the shape of the objects. In this paper we present three approaches for detecting edges in 3-D range data. The ap...Range data; Edges; Recognition scheme; 3-D1985
142 Arc and path consistency revisitedMackworth and Freuder have analyzed the time complexity of several constraint satisfaction algorithms [4]. We present here new algorithms for arc and path consistency and show that the arc consistency algorithm is optimal in time complexity and of the same order space complexity as the earlier algor...Arc consistency; Path consistency; Constraint satisfaction algorithms1985
143 Recognition of 2-D occluded objects and their manipulation by PUMA 560 robotA new method based on a cluster-structure paradigm is presented for the recognition of 2-D partially occluded objects.

145 The synthesis of visual recognition strategiesA coherent automated manufacturing system needs to include CAD/CAM, computer vision, and object manipulation.
