The data visualization on small mobile devices, such as PDAs or smartphones, is a critical aspect to make appropriate and on-time decisions. This criticality particularly occurs due to the small size of their screens to show geographical data. This article presents a strategy to select and display the most relevant “Points of Interest” on a digital map, according to the emergency influence area. This strategy was implemented on the MobileMap tool, and then it was evaluated through simulated emergency situations.

Efficient resource allocation for connections that need guaranteed QoS is only possible if the application can provide a precise and reliable traffic descriptor that the network can understand. This work presents a methodology to obtain the parameters of the traffic descriptor of an ATM application from an initial sample of the flow. Based on real-time measurements of the flow, we suggest periodic renegotiations of the parameters, every time they vary above or below their predefined limits. We apply this method to a VBR MPEG video flow and demonstrate its performance. Observed results are discussed and some future uses of the methodology are suggested. \u0000 \u0000 \u0000","PeriodicalId":30032,"journal":{"name":"CLEI Electronic Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43526577","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}

Various studies already propose to extend FPA, mainly aimed at achieving greater precision in the point assessment of systems of greater algorithmic complexity. This work proposes the use of concepts and properties from fuzzy set theory to extend FPA to FFPA (Fuzzy Function Point Analysis). Fuzzy theory seeks to build a formal quantitative structure capable of emulating the imprecision of human knowledge.

However, when these methods are applied to the enterprise context, it is very unclear what an application domain means. To solve this problem, we elaborate the notion of business system and propose a method based on such notion for modeling application domains of Enterprise Information Systems (EIS). This method helps EIS development teams to get comprehensive knowledge about EIS application domains. This knowledge is expressed in terms of the fundamental concepts of a business system: goals, technologies, business rules, business processes, business objects, actors, job structure, and events. The method is described in terms of three methodological components: a product model, a process model, and a team model. This structure facilitates the explanation, understanding and application of the method. \u0000 \u0000 \u0000","PeriodicalId":30032,"journal":{"name":"CLEI Electronic Journal","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67759147","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 particular, the School of Informatics has been exploring the opportunities to implement, through the use of a pedagogy oriented to problems and projects, a curricular integration between diverse areas of knowledge in the curriculum. From this perspective and with the aim of integrating the areas of programming, databases and systems engineering, an initial exploratory study was carried out with faculty members and a group of students from the fourth level of the curriculum. The findings show several limitations, such as mismatches between the course contents, lack of faculty commitment to collaborative work and student resistance. They also show the need of establishing strategies to create, from the early years of the curriculum, the necessary conditions to promote a positive attitude towards curricular integration processes and therefore overcome, at least partially, the identified limitations.","PeriodicalId":30032,"journal":{"name":"CLEI Electronic Journal","volume":"17 1","pages":"11-11"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67758981","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 BPs modeled with BPMN being able to support business designers, BPMN models are not appropriate to support the analysis phase. BPMN models have no formal semantics to conduct qualitative analysis (validation and verification). In this work is presented how Model Checking (MC) verification technique for software and Timed Automata (TA) formal language are integrated within a formal verification approach to check BPs modeled with BPMN. Also, are introduced a set of guideline to transform BPMN models into TA. The use of our approach allow to business analysts and designers to perform evaluation (i.e., qualitative analysis) of BPs, based on the formal specification of BP–task model with TA. The application of the approach is aimed to evaluate the behavior of the BP–task model with respect to business performance indicators (for instance, service time, waiting time or queue size) derived from business needs, as is shown in an instance of an enterprise–project related to Customer Relationship Management.","PeriodicalId":30032,"journal":{"name":"CLEI Electronic Journal","volume":"17 1","pages":"3-3"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67758759","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}
