The problem of obstacle avoidance as a low-level, nonintellectual task that should operate in complex, noisy, dynamic, and 3-D domains is considered. Two algorithms are presented, each generating qualitatively different solutions. The first generates the shortest path between two locations; the second generates the clearest path between two locations. Both are based on the distance transform.<<ETX>>","PeriodicalId":377124,"journal":{"name":"Proceedings. 5th IEEE International Symposium on Intelligent Control 1990","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115724252","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 procedure aims to improve the network performance by online adjustment of protocol parameters. The techniques of perturbation analysis in discrete-event dynamical systems, stochastic approximation, and learning automata are used in formulating the performance management procedure. The prototype procedure is evaluated on a test apparatus which consists of a number of host computers interconnected by an IEEE 802.4-based MAP network, and test results are presented and discussed. The conceptual design offers a step forward to bridging the gap between management standards and users' demands for efficient network operations, since most standards, such as ISO and IEEE standards, address only the architecture and interfaces for network management. The proposed concept of performance management can be used as an offline tool for selecting default parameter settings of a network.<<ETX>>","PeriodicalId":377124,"journal":{"name":"Proceedings. 5th IEEE International Symposium on Intelligent Control 1990","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115285703","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 risk of making adjustments can be deceased by building a model of the process and experimenting with changes to the controls of the model rather than to those of the actual process. A connectionist (neural) network learns a nonlinear process model by observing a simulated manufacturing process in operation. The objective is to use the model to estimate the effects of different control strategies, removing the experimentation from the actual process. Previously it was demonstrated that a linear, single-layer connectionist network can learn a model as accurately as a conventional linear regression technique, with the advantage that the network processes data as they are sampled. Here, experiments with a multilayer extension of the network that learns a nonlinear model are presented.<<ETX>>","PeriodicalId":377124,"journal":{"name":"Proceedings. 5th IEEE International Symposium on Intelligent Control 1990","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131377677","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}

It is shown that a number of tools are available to the user of acoustic emission, making it possible to apply the technique to a variety of problems. By way of example, the authors discuss a laboratory study in which acoustic emission events from a fatigue test are monitored and a large number of selected signals are digitally recorded. The event trends and signals are analyzed in order to discriminate between acoustic events associated with material defects and those produced by other benign sources. By the use of both physical arguments and pattern recognition techniques which are empirical or statistical in nature, these results are related to the failure processes taking place within the specimen.<<ETX>>","PeriodicalId":377124,"journal":{"name":"Proceedings. 5th IEEE International Symposium on Intelligent Control 1990","volume":"124 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131324822","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 proposed algebra allows for the hierarchical specification of the flow of control and the temporal order of task execution by multiagent systems. Each level of the resulting hierarchies horizontally contains the synchronization structure of task execution and vertically is a generalization of the level below and a specialization of the level above. The horizontal synchronization structures developed by the proposed Petri net model maintain the desirable properties of safeness and liveness by construction. The model utilizes a modularization of complex kinematic chains, a classification of primitive tasks, and a concept of functional time dependency.<<ETX>>","PeriodicalId":377124,"journal":{"name":"Proceedings. 5th IEEE International Symposium on Intelligent Control 1990","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127037398","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}

Some of the practical issues relating to this approach and alternatives in the form of offline compilation of decision models and learning systems to circumvent the need for accurate predictive models are examined.

The 'neural servocontroller' is based on a neural network which has integrated time-delay elements so that it can learn the nonlinear dynamical system The controller is applicable to position and force control of robotic manipulators. Because they have strong nonlinearity and are high-speed phenomena, it is difficult to sense collisions and to control robotic manipulators suffering collisions. Therefore, the neural servocontroller is effective against collision phenomena. A Herz-type model with an energy loss parameter was adopted to express the impact force between the manipulator and unknown objects. Simulation results show that the proposed neural servocontroller can sense collision phenomena and control robotic manipulators suffering collision.<<ETX>>","PeriodicalId":377124,"journal":{"name":"Proceedings. 5th IEEE International Symposium on Intelligent Control 1990","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123444654","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}
