Robot simulator in TIPS/Geometric Simulator

Abstract: With the growth of factory automation, the need for off-line robot programming is increasing rapidly. Off-line programming requires a robot simulator. This is the reason for the development of a TIPS/GS (Geometric Simulator), accompanied by a robot simulator. TIPS/GS has been developed as a project in the TIPS Research Association. The goal of this project is to extend the functions and applications of the solid modeler TIPS-1. Four simulators (i.e. the assembly simulator, engineering, NC simulator and robot simulator) have been developed for these extended applications. The robot simulator described in this paper has the following special features: • • When a robot motion is prescribed by the VAL-G language, the result can be seen on a CRT display in several patterns. • • High-speed dynamic display which can almost keep up with real-time movements. • • A shaded as well as wire-frame picture is used for the high-speed display entioned above. • • Supported by the solid modeler, any robot and environment can be used with this system. • • The preparation of a precise interference checker based on an analytical methods. This paper is a report on the development of the robot simulator.

Theory of Grease Lubrication of Cylindrical Rooler Bearing

Abstract: The lubrication theory on the substances of rheological behaviour as grease is a recent theme. In particular, as the grease is often used for the lubrication of rolling bearing, it is important to establish a theory of grease lubrication for rolling bearings. In this paper, considering the grease as a Bingham plastic, a theory of grease lubrication for cylindrical roller bearing has been deduced. That is, the special core formation in grease film, the frictional resistance of rolling bearing, the pressure distribution and the load capacity of grease film entrapped between roller and race of cylindrical roller bearing have been researched. In addition, the above grease lubrication theory is compared with the oil lubrication theory.

Bibliography of Self-Organizing Map (SOM) Papers: 1981-1997

Abstract: The Self-Organizing Map (SOM) algorithm has attracted an ever increasing amount of interest among researches and practitioners in a wide variety of elds The SOM and a variant of it, the LVQ, have been analyzed extensively, a number of variants of them have been developed and, perhaps most notably, they have been applied extensively within elds ranging from engineering sciences to medicine, biology, and economics We have collected a comprehensive list of 3343 scienti c papers that use the algorithms, have bene ted from them, or contain analyses of them The list is intended to serve as a source for literature surveys We have provided both a thematic and a keyword index to help nding articles of interest

Automated high volume slide processing system

Abstract: An automated system is provided for performing slide processing operations on slides bearing biological samples. In one embodiment, the disclosed system includes a slide tray holding a plurality of slides in a substantially horizontal position and a workstation that receives the slide tray. In a particular embodiment, a workstation delivers a reagent to slide surfaces without substantial transfer of reagent (and reagent borne contaminants such as dislodged cells) from one slide to another. A method for automated processing of slides also is provided.

A restricted Lagrangean approach to the traveling salesman problem

Abstract: We describe an algorithm for the asymmetric traveling salesman problem (TSP) using a new, restricted Lagrangean relaxation based on the assignment problem (AP). The Lagrange multipliers are constrained so as to guarantee the continued optimality of the initial AP solution, thus eliminating the need for repeatedly solving AP in the process of computing multipliers. We give several polynomially bounded procedures for generating valid inequalities and taking them into the Lagrangean function with a positive multiplier without violating the constraints, so as to strengthen the current lower bound. Upper bounds are generated by a fast tour-building heuristic. When the bound-strengthening techniques are exhausted without matching the upper with the lower bound, we branch by using two different rules, according to the situation: the usual subtour breaking disjunction, and a new disjunction based on conditional bounds. We discuss computational experience on 120 randomly generated asymmetric TSP's with up to 325 cities, the maximum time used for any single problem being 82 seconds. This is a considerable improvement upon earlier methods. Though the algorithm discussed here is for the asymmetric TSP, the approach can be adapted to the symmetric TSP by using the 2-matching problem instead of AP.

Review of dimensioning and tolerancing: representation and processing

Abstract: The paper surveys the current state of knowledge of techniques for representing, manipulating and analysing dimensioning and tolerancing data in computer-aided design and manufacturing. The use of solid models and variational geometry, and its implications for the successful integration of CAD and CAM, are discussed. The topics explored so far can be grouped into four categories: (a) the representation ot dimensioning and tolerancing (D& T), (b) the synthesis and analysis of D& T, (() tolerance control, and (d) the implications of D& T in CAM. The paper describes in detail the recent work in each group, and concludes with speculation on a general framework k)r future research.
