One essential attribute of reusable software architecture is that it effectively isolates the logical, or static, aspects of the application from any product specific variations in the physical architecture, or execution environment. A primary element of this isolation is hardware and low-level software (e.g. operating system) independence. A design pattern documents a reference design for the solution to a recurring problem encountered in object-oriented software development. The fundamental theme of design patterns is to encapsulate the concepts that vary. This paper describes our experiences on developing reusable object-oriented software architecture for GCS (Ground Control Station) for UAV (Unmanned Aerial Vehicle) using design patterns. In addition, various ways that software architecture attributes can be designed for flexibility without introducing volatility into the physical architecture are described.","PeriodicalId":112012,"journal":{"name":"2010 36th EUROMICRO Conference on Software Engineering and Advanced Applications","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127382926","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 this becomes feasible only if the dependability attributes, such as reliability, of embedded systems can be properly estimated and guaranteed using appropriate models. Another recent trend is the prevalence of architectural modelling of software systems due to the advantages such as composability reasoning and analysis of system behaviour as well as the flexibility and reusability of models. However, a major issue is that there exist uncertainty in the reliability parameters associated with the traditional testing-based approaches for particular architectural entities (e.g. components and/or connectors). In this context, we propose a new approach for the reliability estimation of component-based software systems, which steps on an architectural model of the system using Generalized Nets. This notation is a generalization of Petri nets and is an all-purpose formal modelling technique for the description of parallel phenomena. For the reliability description, we apply possibility theory, which has the potential to solve the uncertainty aspect. This is based on fuzzy sets and describes reliability properties of software components in systems architecture with fuzzy measures.","PeriodicalId":112012,"journal":{"name":"2010 36th EUROMICRO Conference on Software Engineering and Advanced Applications","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126906741","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}

We have collected process, product and resource metrics from past projects together with the effort values distributed among software life cycle phases, i.e. analysis & test, design & development. We have used Clustering approach to form consistent project groups and Support Vector Regression (SVR) to predict the effort.

The components must provide new metadata about their temporal behaviour and resource usage in order to schedule the applications in which they are used. The extension is formulated at platform independent model (PIM) level, based only on the models of component and application introduced in D&C, and on the requirements introduced by a reactive real-time paradigm. The extension is strictly compatible with the metamodel and the process defined in current D&C, adding some new modelling elements to the metamodel and new optional phases to the design application process, which are specific of applications with real-time requirements.","PeriodicalId":112012,"journal":{"name":"2010 36th EUROMICRO Conference on Software Engineering and Advanced Applications","volume":"431 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116279459","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}

Among these functionalities, particular emphasis is put on the analysis phase which permits to use several reasoners able to take decisions with multiple temporal scopes, at short term as well as at long term. Specific attention is also paid to the planning phase, which enables to schedule parallel actions while taking into account different constraints.","PeriodicalId":112012,"journal":{"name":"2010 36th EUROMICRO Conference on Software Engineering and Advanced Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128892618","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}

Component protocols ensures that bugs or unsafe behavior caused interaction sequences are obeyed. Encoding business rules works fine as these contracts can be derived from human knowledge only and have to be defined manually, too. In this work we will show, how such unsafe behavior within source code can be discovered and prevented by automatic component protocol generation and model checking techniques.","PeriodicalId":112012,"journal":{"name":"2010 36th EUROMICRO Conference on Software Engineering and Advanced Applications","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127830673","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}
