The definition of a numerical context means the configuration of resources such as memory, processor load and communication graph, with an evolving feature: the resources availability. A feature is often missing: the adaptability. It is not predictable and the adaptable aspect is essential. Without calling into question these implementations of these codes, we create an adaptive use of these implementations. Because the execution has to be driven by the availability of main resources, the components of a numeric computation have to react when their context changes. This paper offers a new architecture, a mobile computing architecture, based on mobile agents and JavaSpace. At the end of this paper, we apply our architecture to several case studies and obtain our first results.","PeriodicalId":305315,"journal":{"name":"International Conference on Mobile Ubiquitous Computing, Systems, Services and Technologies (UBICOMM'07)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130269356","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}

A Scheme for Adapting TCP to Drastic Changes in Link Characteristics 一种使TCP适应链路特性急剧变化的方案

{"title":"A Scheme for Adapting TCP to Drastic Changes in Link Characteristics","authors":"K. Ishibashi, N. Morishima, H. Sunahara","doi":"10.1109/UBICOMM.2007.4","DOIUrl":"https://doi.org/10.1109/UBICOMM.2007.4","url":null,"abstract":"The mobile environment has been improved in this decade with technologies of mobility transparency such as mobile IP (MIP) and network mobility (NEMO), plus there has been progress in wireless and device technologies. Mobility transparency makes it possible for a mobile node to change its upstream data-link without any disruption of existing TCP connections. However, these technologies do not suffice for TCP to retain its performance, since they do not hide any changes in link characteristics. In this paper, we propose a scheme which adapts TCP congestion control to link characteristics after the upstream data-link changed. This scheme is based on a (re)setting of the parameters used for TCP congestion control after a upstream data-link changed. Some strategies of how parameters are derived, and when they are set, are discussed and examined here. We also implemented the scheme and carried out emulation experiments, the results of which demonstrated the scheme can avoid a adverse affect caused by a changes in the upstream data-link and make the TCP congestion control to adapt the changes in link characteristics.","PeriodicalId":305315,"journal":{"name":"International Conference on Mobile Ubiquitous Computing, Systems, Services and Technologies (UBICOMM'07)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132498223","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}

Following studies of unsuccessful Wiki projects, a field study was undertaken of a corporate Wiki that has been developed to capture, and make available, organizational knowledge for a large manufacturing company as an initiative of their knowledge management program. A Q methodology research approach was selected to uncover employees' subjective attitudes to the Wiki so that the firm could more fully exploit the potential of the Wiki as a ubiquitous tool for tacit knowledge management.","PeriodicalId":305315,"journal":{"name":"International Conference on Mobile Ubiquitous Computing, Systems, Services and Technologies (UBICOMM'07)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125267690","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}

A \"Lunar Observation Support System\" that can be used with mobile phones was developed. Using this system, students observe the Moon in the open air and send observational data through their mobile phones to the server; the server automatically stores the data in a database. The system also possesses a computer- supported collaborative learning (CSCL) feature through which students can share observational data with each other and engage in discussions. From a practical study, we found that students were able to send lunar observational data from their mobile phones effortlessly from the outdoors, and their interest, attention, attitude, and motivation toward nature observation improved. In addition, sharing each student's observational record on the Web Database and engaging the students in discussions led to the correction of simple false beliefs that students often have, such as \"the Moon can be seen only during the night\" and \"the Moon rises at the same time everyday\".","PeriodicalId":305315,"journal":{"name":"International Conference on Mobile Ubiquitous Computing, Systems, Services and Technologies (UBICOMM'07)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126712624","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}

MetaSemflow proposes a metadata vertical integration by combining a multi-faceted resource categorization approach to a topic maps-based semantic management including contextual semantics (e.g. 5W1H model).
