The paper focuses on the \"sheepdog problem\" that handles distributed autonomous robot systems. This problem is an extension of the \"pursuit problem\" that handles one prey robot and multiple predator robots. The sheepdog problem challenges to handle more complex issue, that is, multiple dog robots try to chase and capture multiple sheep robots. In this paper, we propose the use of Boids model and cellular automata to model the flocking behavior for the sheep robots, and the chasing and capturing behavior for the dog robots. We demonstrate an experiment of the sheepdog problem.","PeriodicalId":160588,"journal":{"name":"2006 IEEE International Conference on Computational Cybernetics","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122082977","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}

Under such conditions the clustering system can provide a much cleaner result by rejecting the classification of documents with ambiguous topic. This is achieved by applying a confidence measurement for every classification result and by discarding documents with a confidence value less than a predefined lower limit. This means that our system returns the classification for a document only if it feels sure about it If not, the document is marked as \"unsure\". Beside this ability the confidence measurement allows the use of a much stronger term filtering, performed by a novel, supervised term cluster creation and term filtering algorithm, which is presented in this paper as well.","PeriodicalId":160588,"journal":{"name":"2006 IEEE International Conference on Computational Cybernetics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130727120","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 control strategy is applied to a six-dof parallel robotic mini-manipulator: the robotic controlled impedance device (RCID). The control strategy involves three cascade controllers: an inner acceleration controller, built as a set of six single-input- single-output (SISO) acceleration controllers (one per manipulator axis), an impedance task-space controller, and an outer force controller. The proposed control strategy enables two kinds of manipulator behaviour: force limited impedance control and position limited force control. The type of behaviour only depends on the chosen manipulator trajectories. The RCID may be used as a force-impedance controlled auxiliary device, coupled in series with a position controlled industrial robot, or as a stand-alone force feedback display, that may be used as a master manipulator in master-slave telemanipulated systems or as a haptic device interacting with virtual environments. Experimental results of the RCID used as an auxiliary device working coupled to an industrial manipulator are presented.","PeriodicalId":160588,"journal":{"name":"2006 IEEE International Conference on Computational Cybernetics","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128193654","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}

First, it is explained that in such cases there can be many functions implemented by neural networks that will accurately approximate training patterns. Then it is pointed out that many of these functions do not allow for proper estimation of the inputs importance using the sensitivity analysis method for neural networks. These two facts are demonstrated to be the reason why one can not completely rely upon the results of this method, when evaluating a real importance of inputs. Examples with graphs visualizing the discussed phenomena are presented.

This research aims to provide a broader understanding of how closer interaction between these two entities can facilitate more optimal goal related performance through the use of artificial extension of the human body. Such extension may assist us in adapting to and manipulate our environments in a more effective way than any organism observed to day. To demonstrate this concept, the researchers have developed a simulation where a semi interactive virtual spider can be navigated through an environment that includes several obstacles and a virtual predator capable of killing the spider. The virtual spider in turn, can be navigated through the use of three different control systems that when combined optimises overall goal related performance. An onscreen button interface and a touch sensor facilitate human navigation of the spider, while a third control system is based on automatic navigation through the use of Classical AI. The last mentioned control system enables the spider to navigate and react to changes in its local environment with the benefits provided by machine intelligence. The results of this study indicate that machines should be allowed to disobey human control, to obtain optimal benefits of man machine collaboration. This research further indicates that the development of; Strong AI; sensor systems that engage all human senses; extra sensory input systems; physical remote manipulators; intelligent extension of the human body; and a tighter symbiosis between man and machine can support an upgrade of the human form.","PeriodicalId":160588,"journal":{"name":"2006 IEEE International Conference on Computational Cybernetics","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132563088","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}

This algorithm relaxes the necessary conditions on the coefficients of the Lyapunov-like function to a system of linear interval inequalities that can then be solved exactly, and iteratively reduces the relaxation error by recursively decomposing the state space into hyper-rectangles.

But complaints on software quality are getting more and more common. Software quality depends on many factors and sometimes also universities are blamed - they do not teach the essential skills, that software engineering (SE) education provides too theoretical or old-fashioned courses. Curriculum is a complex emerging system; here are analyzed factors which influence it. The main conclusion is that software is a process and its quality follows from the process quality. Process quality is reached by disciplined practices during the development. Traditionally, software development is based on the predefined path of development phases, which all have their purpose, base practices and outcomes. Opposite to this, there is a trend towards light process oriented software development culture - agile development. In this approach, team work, active role of the client, and incremental product architecture is important. Software development is highly human oriented sector of industry. Productivity can not be increased - at least not dramatically - by tools and automation. New approaches in software industry are based on higher level of automation and reuse of available software assets. Large scale software development is based on reusable platforms, product families, artifacts developed by component factories, but finally especially in the intelligence of the professionals modifying and further developing the available artifacts. In spite of the improvement in automation in \"large scale\" software development, the main part of software is still developed in very traditional way - from the scratch based on careful user requirements elicitation, specification, system design and implementation. SE curriculum should correspond to the industry needs, only then can universities produce highly skilled professionals, which can satisfy needs of software industry. Development of curricula is supported also by different standards, frameworks and recommendations developed by different interest groups, but the role of these \"global\" curricula models in the development of high quality university curricula should not be over-estimated. Different approaches in SE curriculum development are introduced. The experiences of authors provide a path of tested \"good practices\" towards a new curriculum structure implemented in the organizations of the authors.","PeriodicalId":160588,"journal":{"name":"2006 IEEE International Conference on Computational Cybernetics","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116754057","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}
