First, the main groups of modeling activities are characterized from the point of view of concurrence and actual problems are outlined. Following this, the possible role of collaborative engineering methods is emphasized. Then an approach to concurrent modeling in a collaborative environment is proposed. Finally, the most important future development areas are considered.","PeriodicalId":161975,"journal":{"name":"Proceedings of IEEE International Conference on Intelligent Engineering Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133105291","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous works on shape and motion from optical flow have been unsatisfactory because they require solving nonlinear simultaneous equations using iterative search. In the present paper, we propose a method for the recovery of motion and structure from perspectively projected optical flow of feature points which move rigidly. In order to simplify the computation and obtain clear perspectives, we adopt a spherical image screen and arrange equations in linear form. As a result our method does not require the solution of nonlinear simultaneous equations, but only requires the solution of linear ones. Furthermore, we propose a method for refining the solution of our linear method using a nonlinear iterative search. Simulation results of our method are also presented.","PeriodicalId":161975,"journal":{"name":"Proceedings of IEEE International Conference on Intelligent Engineering Systems","volume":"189 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114201211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this case the antecedent and consequent fuzzy partitions (formed by these primary fuzzy sets) can be described by vague environments. Using the concept of vague environment characterized by scaling functions instead of the linguistic term fuzzy sets gives a simple way for fuzzy approximate reasoning. Comparing the description of a universe given by a fuzzy partition to the way of using the concept of vague environment, we can say that the linguistic terms of the fuzzy partition are crisp points in the vague environment, while the shapes of the fuzzy sets (density information) are described by the scaling function. The primary fuzzy sets of the antecedent and the consequent parts of the fuzzy rules can be characterised by crisp points in their vague environments, so the fuzzy rules themselves are points in their vague environment too (in the vague environment of the fuzzy rule base). It means, that the question of approximate fuzzy reasoning can be reduced to the problem of interpolation of the rule points in the vague environment of the fuzzy rule base relation. In other words, using the concept of vague environment, in most cases we can build approximate fuzzy reasoning methods simple enough to be a good alternative to the classical Compositional Rule of Inference (CRI) methods in practical applications. In this paper two methods of approximate fuzzy reasoning based on interpolation in the vague environment of the fuzzy rule base, and a comparison of these methods to the classical CRI are introduced.","PeriodicalId":161975,"journal":{"name":"Proceedings of IEEE International Conference on Intelligent Engineering Systems","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130594855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When the path of the motion is given (CPC problem) it can be proved that time-optimal motion is realized when at least one of the joint velocities is at its maximum value. Which joint's velocity should be at maximum depends on the position in working space, and the maximum velocity values of joints, and can be determined by simple general method. The authors consider the following problem: The robot end effector centre point should move between two points (PTP problem) for minimum time and also satisfying the conditions of energetical optimality. A motion is energetically optimal when there is no energy lost for not needed changes of kinetic energy of the robot mechanisms. A simple method is given for the determination of minimum time cruising PTP motion. All of the realizable trajectories inside the attainable domain of motion realize minimum time. From these trajectories the energetically optimal can be determined using the dynamic model of robots in Riemann space. As side results, the problem of when the motion on a straight line takes more time than on some other, and energetically optimal motion along a given path, is also solved.","PeriodicalId":161975,"journal":{"name":"Proceedings of IEEE International Conference on Intelligent Engineering Systems","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133849878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The incremental motion encoder (IME) is a new type of rotary motion sensor that can measure the relative motion between a shaft and its supporting bearing. This motion is directly related to the condition of the bearing. The advantage of this method, over the measurement of transmitted vibration, is that the signal is not attenuated in transmission or distorted by other vibration sources. An experiment demonstrating the ability of an experimental IME device to detect distinct changes in the shaft centre displacement related to bearing corrosion is described to illustrate the IME principle. Based on our work we propose that a bearing constructed with an integrated IME sensor could sense its own condition as well as external factors such as loading and imbalance. A sensor-based or smart bearing of this new type could be an effective condition monitoring and process control sensor for machine tools and other rotary equipment.","PeriodicalId":161975,"journal":{"name":"Proceedings of IEEE International Conference on Intelligent Engineering Systems","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134427893","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
