MSCs are commonly used to specify scenarios describing message exchange among entities such as objects, components, systems, etc. A multiplicity is a modeling construct that is used to define constraints in the existential relationships between entities and it is frequently found in static models, such as class or entity diagrams. This paper describes a formal approach for formalizing the combination of MSCs with multiplicities. The formalization is achieved by defining an instantiation partial function that provides a clear interpretation of how to instantiate MSCs with multiplicities. The formalization uses composition operators that are used to formalize inline expressions (a well-known MSCs modeling construct). This formalization is designed to allow integration with the current formal semantics proposed for MSCs","PeriodicalId":432491,"journal":{"name":"2006 Seventh Mexican International Conference on Computer Science","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130492382","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}

For this reason various languages for design and implementation of business processes such as Business Process Execution Language for Web services (BPEL) have arisen. However, a weakness of these languages is the difficulty to be used by business analysts in the early stages of the development process. In this work we present, through a case study, a model-driven process for the service composition modeling. The process begins with the identification of the services that will be offered to the user, taken into account the system requirements; and allows to obtain a service composition model. From this model it is possible the mapping to a specific Web services composition language","PeriodicalId":432491,"journal":{"name":"2006 Seventh Mexican International Conference on Computer Science","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126621515","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 respect, CSCL provides the technological infrastructure to conduct effective learning methodologies, since it allows the definition of new scenarios of learning as a social endeavor along with the means for their evaluation. In this paper, it is proposed the design of a methodology for the constructivist approach of collaborative learning based on the scientific method and the implementation of a Web-based framework for a course of logic circuits that support this model. The main contributions consist in (i) using the scientific method as a fundamental model for the acquisition of new knowledge derived from using software artifacts discovered and contributed by a community of students, and (ii) developing a computer-based framework that instruments this model in a new generation of CSCL frameworks","PeriodicalId":432491,"journal":{"name":"2006 Seventh Mexican International Conference on Computer Science","volume":"19 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132289414","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}

These systems can be represented by means of the \"physical agent\" paradigm. One typical implementation of physical agents is autonomous mobile cooperative robots. In our approach the physical agents have different automatic controllers to generate dynamical diversity in the team-work. Here, dynamic means dynamic temporal evolution of continuous variables of the controlled system. Therefore, the multi-agent systems can be considered as a team of heterogeneous intelligent agents with different capabilities that work together to fulfil some cooperative tasks. In particular, this paper is related to studies about how the team-work improves by the \"degrees of situation\" management.

The method is based on interpreting the components of signal models as nodes in a sparsely connected network of overlaps (scalar products). Every point in the data sample expresses an overlap. Networks of this kind, in which nodes carry information by means of vectors, define a knowledge network, a recently introduced concept in the field of statistical physics. Previous results on the statistical properties of knowledge networks are generalized to noise reduction and its shown that is possible to extract important hidden quantities.

A \"Smart Home\" is a type of intelligent environment that can provide such a place for this experiential learning. Smart Homes continue to entice us with their promise of anticipating and meeting our needs as they unobtrusively adapt to our changing preferences and goals. The delivery of this promise, however, has met with limited success in terms of functionality and user acceptance. Many commercial and academic efforts are in progress to create true smart home systems.
