In these spaces of cooperative knowledge, each organization contributes with their partners providing learning resources that they offer to students and teachers. Each organization manages their resources and students. However, there is a problem. The Learning Management Systems (LMS) that gives support to the development of the joint degrees have not been conceived to allow multiple spaces of cooperation, which is generating technological isolation. One of the reasons is the lack of knowledge of the joint degrees framework in e-learning environments. The purpose of this document is, first to contribute to the solution of the problem, describing a conceptual model that allows understanding of these cooperative spaces. Second, being useful during the design and development of cooperative e-learning activities and finally to serve as a reference for the design of the new LMS and the adaptation of the present ones.","PeriodicalId":165011,"journal":{"name":"Euro American Conference on Telematics and Information Systems","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123199642","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}

Furthermore this work presents diverse tests to compare the results reached with and without the noise reduction in the image derivatives, and using the nonlinear minimization of an error function. A remarkable improvement in the segmentation quality and the processing time can be observed in every experiment when using the proposed method.","PeriodicalId":165011,"journal":{"name":"Euro American Conference on Telematics and Information Systems","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115407091","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 critical and reflective approach is done to promote further discussion among teachers to understand the use of m-learning and/or e-learning with their students. A technological description is contrasted with the pedagogical approach because what is really important is the way the technological devices are incorporated within a pedagogical paradigm. The inclusion of m-learning within education may important because of its ≪contextual≫ approach very close to the students and their environment that may transform this technological possibility much more ≪familiar≫ in comparison with the other.

From a technical point of view, the major issues are solved (e.g. solutions for connectivity, broadband mobile networks, synchronization mechanisms, secure protocols etc.). But from a business point of view there is a lack of methodology regarding the alignment of technical solutions to the business needs. As companies face a continuously faster change in business models, legal constraints and customer needs, highly flexible systems are needed to react to changing business processes. Furthemore, the introduction of new mobile systems is often a technology-driven process, pushing the alignment of software and systems to the highly specific, fast changing business needs into the background. This paper introduces a framework summarizing the findings from earlier research and case studies related to this topic. The framework consists of a general reference process for mobile work and of a model explaining influencing factors, optimization goals and their relationships for mobile processes. The framework can be applied for process modeling, simulation and optimization as well as for requirements analysis and return on investment calculations.","PeriodicalId":165011,"journal":{"name":"Euro American Conference on Telematics and Information Systems","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121946193","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}
