    Developing with Model Driven Architecture is nowadays widely used starting with a CIM that can be transformed to models of low abstraction (PIM, PSM) that can be used to generate the code. The CIM represents the highest level of abstraction of the approach which allowing modeling system’s requirement. However, there is no standard method to build this type of model or how to transform it to lower level of abstraction (PIM) which is considered the final objective of building such model. This paper provides an approach to build the CIM that can be transformed (semi-) automatically later to lower levels of abstraction in PIMs.  Thereby, the proposed architecture represents both the static and dynamic view of the system based on the business process model. Meanwhile, the PIM level is represented by the Domain Diagram class and Sequence Diagram of Systems External behavior. Thus, the proposal helps bridging the gap between those that are experts about the domain and its requirements, and those that are experts of the system design and development.

    Failed software projects are often the result of an unsystematic transfer of business requirements to the implementation. This deficit led to the specification of the Model Driven Architecture (MDA). It claims a consistent use of conceptual models for the software development process from requirement analysis to technical specification of software. The MDA reduces the gap between the business level and the information technology (IT) level by defining a methodological framework to link these levels (Business-IT alignment). We will present the use of an MDA in health care domain. For this purpose, we show how the paradigm of MDA can be configured to implement medical application software based on a telemedical IT platform (telehealth platform). Additionally to the conceptual structure of the developed approach and the domain-specific alignment, lessons learned from the experiences gathered during design process will be formulated as assistance for similar projects and substantiated with an exemplary application

    Optimal power flow solution with current injection model of generalized interline power flow controller using ameliorated ant lion optimization

    Optimal power flow (OPF) solutions with generalized interline power flow controller (GIPFC) devices play an imperative role in enhancing the power system’s performance. This paper used a novel ant lion optimization (ALO) algorithm which is amalgamated with Lévy flight operator, and an effectual algorithm is proposed named as, ameliorated ant lion optimization (AALO) algorithm. It is being implemented to solve single objective OPF problem with the latest flexible alternating current transmission system (FACTS) controller named as GIPFC. GIPFC can control a couple of transmission lines concurrently and it also helps to control the sending end voltage. In this paper, current injection modeling of GIPFC is being incorporated in conventional Newton-Raphson (NR) load flow to improve voltage of the buses and focuses on minimizing the considered objectives such as generation fuel cost, emissions, and total power losses by fulfilling equality, in-equality. For optimal allocation of GIPFC, a novel Lehmann-Symanzik-Zimmermann (LSZ) approach is considered. The proposed algorithm is validated on single benchmark test functions such as Sphere, Rastrigin function then the proposed algorithm with GIPFC has been testified on standard IEEE-30 bus system

    Reconciling Environmental Policy with Employment, International Competitiveness and Participation Requirements

    Politicians understand that a conventional double dividend policy - defined asreduction of greenhouse gas emissions and unemployment through taxation of energy and CO2emissions and subsidization of wage costs - and the aim of keeping international competitivenessof all sectors intact may be mutually exclusive concepts at least as long as internationallycoordinated solutions are not available. It is suggested that a double dividend policy that aimsat reducing GHG emissions and unemployment without a direct violation of internationalcompetitiveness has to tax energy use and CO2 emissions of households and should use therevenues to subsidize investment in energy or pollution-saving technologies to reduce investmentcosts of firms. Thereby reduction of energy coefficients is achieved together with lowers costsand prices of goods. This is an increase in competitiveness and employment in anenvironmentally friendly way and may induce other parts of the world to participate in GHGemission reduction policies or speed up the achievement of an internationally cooperativesolution. According to this proposal the principle of causation has to be dropped in partnationally but not internationally. Using these positive incentives, competitiveness of sectors willonly be affected through indirect general equilibrium effects.research and development ;

    This study focuses on model-to-model – M2M – transformations, as part of the Model- Driven Development – MDD – approach, for Rich Internet Applications – RIA. The main aim of this study is to identify fields that require further contributions, and/or research opportunities in the previously mentioned context. We applied mapping studies techniques, since these techniques use the same basic methodology as reviews but are more general and aimed at discovering what the research trends are, allowing to identify gaps in the literature. From an initial set of 132 papers, we selected 30 papers first. Then, thanks to experts’ suggestion, we added 3 additional papers. Therefore, we considered 33 research papers. The performed analysis led to various considerations. Among the important ones, we can mention: there are many newly proposed methods, the scarcity of rigorous and formal validation of such methods, the problem of the portability of Platform Independent Models – PIM, and the low number of tools available for MDD.Laboratorio de Investigación y Formación en Informática Avanzad

    Model Driven Engineering (MDE) is gaining ever more strength due to the fact that with MDE the software development can be much more productive and this is the way to go closer to real software industrialization. With MDA TALISMAN, we have succeeded in creating complex software solutions for food traceability adapted to different customers, ready to be deployed. We rely on the approach to MDE most extended at present, MDA (Model-Driven Development) but as we shall see, we also use the main pillars that support the Software Factories, The proposal from Microsoft to MDE. Besides, in this paper we present five cases of success with MDA TALISMAN

    A Model-Driven Architecture based Evolution Method and Its Application in An Electronic Learning System

    Software products have been racing against aging problem for most of their lifecycles, and evolution is the most effective and efficient solution to this problem. Model-Driven Architecture (MDA) is a new technique for software product for evolving development and reengineering methods. The main steps for MDA are to establish models in different levels and phases, therefore to solve the challenges of requirement and technology change. However, there is only a standard established by Object Management Group (OMG) but without a formal method and approach. Presently, MDA is widely researched in both industrial and research areas, however, there is still without a smooth approach to realise it especially in electronic learning (e-learning) system due to the following reasons: (1) models’ transformations are hard to realise because of lack of tools, (2) most of existing mature research results are working for business and government services but not education area, and (3) most of existing model-driven researches are based on Model-Driven Development (MDD) but not MDA because of OMG standard’s preciseness. Hence, it is worth to investigate an MDA-based method and approach to improve the existing software development approach for e-learning system. Due to the features of MDA actuality, a MDA-based evolution method and approach is proposed in this thesis. The fundamental theories of this research are OMG’s MDA standard and education pedagogical knowledge. Unified Modelling Language (UML) and Unified Modelling Language Profile are hired to represent the information of software system from different aspects. This study can be divided into three main parts: MDA-based evolution method and approach research, Platform-Independent Model (PIM) to Platform-Specific Model (PSM) transformation development, and MDA-based electronic learning system evolution. Top-down approach is explored to develop models for e-learning system. A transformation approach is developed to generate Computation Independent Model (CIM), Platform-Independent Model (PIM), and Platform-Specific Model (PSM); while a set of transformation rules are defined following MDA standard to support PSM’ s generation. In addition, proposed method is applied in an e-learning system as a case study with the prototype rules support. In the end, conclusions are drawn based on analysis and further research directions are discussed as well. The kernel contributions are the proposed transformation rules and its application in electronic learning system
