Maglog which is implemented in Java environments is taken up as an example of the agent runtime environment. Maglog consists of three basic components, which are agents, agent servers and fields. Agent server and fields are corresponding to agent runtime environments. The persistency is used for the following two purposes. One is for suspending agents. The other is for suspending a system which is developed by using Maglog. For example, when a computer will be stopped while a system is running, agents are suspended then their suspended state is stored. Subsequently, the agent server is suspended then the suspended state and fields are stored. When the system is restarted, first, the agent server resumes then the agents resume.","PeriodicalId":193808,"journal":{"name":"2007 International Conference on Integration of Knowledge Intensive Multi-Agent Systems","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133687778","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 aglets system is a popular open sourced Java-based mobile agent system, yet it current supports no complete location service solution. This work designs and implements an open sourced location service system for the aglets mobile agent system, which has four major advantages: easy to integrate for legacy applications, easy to join servers in a single region, easy to link among multi-regions for different laboratories, and easy to implement, thus making the range of applications more extensive. Finally, the experimental results demonstrate that our system is efficient in various network environments","PeriodicalId":193808,"journal":{"name":"2007 International Conference on Integration of Knowledge Intensive Multi-Agent Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122047305","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}

Operational context is the abstract context instantiated with the values taken from information sources. It is a situation model along with changeable data.

Sonar data are highly noisy and unpredictable. Sonar does not give the consistent readings for a point from two different positions, so the approaches which rely on correspondence reading matching will prone to fail without exhaustive mathematical calculations of sonar modeling and environment modeling. Also, if features are being use to localize then the robot needs to revisit those features exactly, to localize, which itself will not be accurate because robot will not be at the exact position from where that feature has been detected. Hence it will not get back those feature readings using sonar. Here we are presenting a hybrid approach based on feature chain. Instead of relying completely on feature mapping and point matching, it finds the links between features to localize. It will drastically reduce the need of revisiting a feature to localize and hence reducing the exploration overhead, while handling other issues of problems with point or feature matching. We map features onto occupancy grid (OG) framework taking advantage of its dense representation of the world. Combining features onto OG overcomes many of its limitations such as the independence assumption between cells and provides for better modeling of the sonar implicitly providing more accurate maps","PeriodicalId":193808,"journal":{"name":"2007 International Conference on Integration of Knowledge Intensive Multi-Agent Systems","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121382970","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}

Despite the plethora of available development tools and theories that researchers in agent computing have access to, there is a remarkable lack of general metrics, tools, benchmarks and experimental methods for formal validation and comparison of existing or newly developed systems. It is argued that AT has reached a certain degree of maturity, and it is therefore feasible to move from ad-hoc, domain-specific evaluation methods to standardized, repeatable and easily verifiable procedures. In this paper, we outline a first attempt towards a generic evaluation methodology for MAS performance. Instead of following the research path towards defining more powerful mathematical description tools for determining intelligence and performance metrics, we adopt an engineering point of view to the problem of deploying a methodology that is both implementation and domain independent.

One of the biggest problems is the requirement to involve \"reality\" in this discussion, bringing forth a lot of unsolved questions regarding the nature of what would be such thing we use to call \"reality\". In this work, we present an attempt of escaping this problem, by re-defining the meaning process (semiosis, according to Peirce), in an entirely mathematical framework. We are calling this \"transposition\" of the Peircean theory to a purely abstract mathematical model as \"mathematical semiosis\". By doing this, we aim at growing a more understandable theory for explaining what is to comprehend, to understand and to mean, in a strictly mathematical sense, avoiding complications related to the connection of signs to a real world. The main application of such a theory would be in order to develop machines with these capabilities.
