But the MAXQ framework cannot decompose all subtasks into more refined hierarchies and the hierarchies are difficult to be discovered automatically. In this paper, a multi-agent hierarchical reinforcement learning approach, named OptMAXQ, by integrating Options into MAXQ is presented. In the OptMAXQ framework, the MAXQ framework is used to introduce knowledge into reinforcement learning and the option framework is used to construct hierarchies automatically. The performance of OptMAXQ is demonstrated in two-robot trash collection task and compared with MAXQ. The simulation results show that the OptMAXQ is more practical than MAXQ in partial known environment","PeriodicalId":202629,"journal":{"name":"First International Multi-Symposiums on Computer and Computational Sciences (IMSCCS'06)","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128573342","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 we amplified the heavy-chain variable regions (VH) gene from one hybridoma cell line which were not amplified successfully under conventional protocols, a novel method was developed to design the degenerated primer of immunoglobulin cDNA and rapid amplification of cDNA ends polymerase chain reaction (RACE PCR) protocols were performed to recognize the VH gene from the hybridoma cell line. The most highly conserved region in the middle of the VH regions of the Ig cDNA was identified and a degenerated 5'primer was designed using our algorithms. The VH gene was amplified by the 3'RACE and 5'RACE. The VH sequence of CSA cells was 399 bp. The new protocol rescued the amplifications of the VH gene that had failed under conventional protocols and notably increased amplification specificity. The algorithm improved the primer design efficiency and is useful in building VH and VL gene libraries or cloning of unknown genes in gene families","PeriodicalId":202629,"journal":{"name":"First International Multi-Symposiums on Computer and Computational Sciences (IMSCCS'06)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134468280","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}

However, it is difficult to implement all the grid semantics on pervasive devices due to the inherent limitations of most pervasive devices. It is not yet clear that how to organize large quantities of heterogeneous pervasive devices collaborating with each other to solve user-centered tasks. And exploiting grid infrastructure to accomplish resource-intensive tasks is still a challenge for resource-weak pervasive devices. In this paper, we put forward the concept of user's task oriented nomadic autonomy domain (UTONAD) which models the pervasive devices collaborating patterns when they are included in a global resource-sharing platform. Based on UTONAD, we propose the architecture of our implementation that provides a uniform method to manage QoS guaranteed interactions between pervasive devices and grid in a dynamic (both temporal and spatial) and user-transparent fashion","PeriodicalId":202629,"journal":{"name":"First International Multi-Symposiums on Computer and Computational Sciences (IMSCCS'06)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125058464","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 paper, we studied and implemented a simple proactive service broking middleware (PSRB) for building PC-based grid that promises a cost-effective approach for high performance computing. It employs a robust mediation server group to centrally serve grid nodes and clients by exchanging their service requests and responses as a message broker. At the same time, it provides a few resource agents to proactively monitor the resources on grid nodes and forecast their future availability. Predictions are accepted as the primary fact for PSRB to select the best grid node for job assignment.

However, with the growing number of Web services available on the Web, such a centralized approach quickly becomes impractical. In this paper, we present a novel distributed Web services catalog system, to support decentralized Web service publication and discovery. By utilizing the distributed hash table (DHT) functionality of peer-to-peer (P2P) computing, Web service catalog information is routed directly to each node in this system, and each node shoulders part of the catalog. But in P2P network, every peer is equally treated, and it does not allow peers with common business interest to federate partnerships. In fact, most applications only focus on publication and discovery of services with interest to their respective business domains. In our work, we have made improvements for this limitation, and proposed the hierarchical Web services catalog system, which enables efficient Web service publication and discovery within a specific business domain.
