Information Systems Development faces many recurrent issues that must be addressed in every project. A lot of common requirements and features repeatedly appear on different projects challenging the development team. Exchanging solutions and the expertise gained over the evaluation of such solutions among projects can prevent the development teams from reinventing the wheel. The MDArte framework has...
Massive multiplayer online games are large-scaled distributed systems to handle a huge amount of simultaneous players. Thus, development costs can be enormous. To deal with this, it is necessary to reduce redundant development steps in such distributed systems, e.g. by using code generators and model analysers to build components from already existing knowledge. Such knowledge could be the unique...
Content Management Systems (CMS) are popular web application platforms used in multiple domains. CMS allow non-technical users to manage the content and features of websites with web modules that abstract functionality without requiring particular software programming background. However, without the development of specific web modules, a CMS usually cannot support complex scenarios or specific business...
Avionics systems, along with their internal hardware and software components interfaces, must be well defined and specified (e.g., unambiguous, complete, verifiable, consistent, and traceable specification). Such a specification is usually written in the form of an Interface Control Document (ICD), and represents the cornerstone of the avionics system integration activities. However, there is no commonly...
The Model-Driven Architecture (MDA) is based on an understanding of a hierarchy of levels that are placed on top of each other and that are connected with instantiation. For practical MDA use, it is important to be clear about the kinds of objects that reside on the different levels and the relations between them as well as relations to objects outside of the MDA domain. This article aims at enhancing...
Because of the thin set of well-formedness rules associated to Templates in UML, ill-formed elements may result from bindings to templates. Although such ill-formedness is generally detected by some UML validation rule, the problem is poorly reported because it is not normally imputed to the binding. Typically, such problems are detected as non-compilable code in the template instances. A set of well-formedness...
Self-adaptive systems are modern applications in which the running software system should be able to react on its own, by dynamically adapting its behavior, for sustaining a required set of qualities of service, and dynamic changes in the context or in user requirements. They are typically involved in Future Internet development such as the Internet of Things where interoperability, flexibility, and...
The possibility to react to unexpected situations in business process execution is restricted since all possible process flows must be specified at design-time. Thus, there is need for a flexible approach that reflects the way in which human actors would handle discrepancies between real-life activities and their representation in business process definitions. In this paper, we propose a novel approach...
Recently modeling techniques are introduced to support safety assessment. Goal Structural Notation is one of these modeling techniques, which can be used to facilitate the development of safety argumentation and create reusable safety argumentation models. Consequently, GSN-based safety cases are widely used to demonstrate the safety of systems in safety-critical domains. Due to the amount of manual...
Enterprise Modeling Languages (EMLs) are generally perceived as conceptual modeling languages having a formal syntax and informal semantics. The non-formality of semantics is mainly caused by the materiality of the addressed domain (enterprises and its related aspects) and the resulting personal interpretation of syntactical constructs. However, EMLs may also explicitly define invariant interpretations...
The paper provides a contextualization process to adapt Open Knowledge Resources for the need of public administrations. By help of a matching strategy, culture and context profiles of learners and learning resources are compared. The comparison allows to draw inferences how to contextualize an open knowledge resource for own learning needs. An example is illustrated and future research fields are...
Embedded devices based on emerging technologies of the Internet of Things (IoT) are used to provide resources, business models and opportunities to build potential industrial systems improving manufacturing systems with efficient operations. In this context, IoT networks are dynamic environments and changes are also being increasingly frequent, modifying the environment execution. Nevertheless, severe...
Support of workplace learning is increasingly important as change in every form determines today's working world in industry and public administrations alike. Adapt quickly to a new job, a new task or a new team is a major challenge that must be dealt with ever faster. Workplace learning differs significantly from school learning as it should be strictly aligned to business goals. In our approach...
Business process variability is an active research area in the field of business process management and deals with variations and commonalities among processes of a given process family. Many theoretical approaches have been suggested in the last years; however, practical implementations are rare and limited in their functionality. In this paper, we propose a new approach for business process variability...
For the transmission of electricity across long distances, high voltage direct current (DC) transmission is discussed in Germany as an alternative to the currently used alternating current (AC) as it is more efficient for these distances. Changes in energy infrastructure are known to raise public awareness. However, little is known whether differences in transmission technology are relevant for the...
These days, surveillance technologies are a key component of smart and networked cities preventing or detecting crime and giving the residents a sense of safety. On the one hand, safety perceptions can be supported by adequate surveillance technologies (e.g., cameras), however on the other hand, the systematic use of surveillance technologies undermines individual privacy needs. In this empirical...
Improving citizens' quality of life is one of the main goals of Smart Cities development. Accessibility of urban public spaces absolutely determines the living conditions for people. Technology provides new opportunities of autonomy for an increasing group of inhabitants with specific disabilities. This work proposes an urban model for improving accessibility based on the design of intelligent environments,...
Urban commons were traditionally defined as commonly owned environmental resources — forests, rivers, fisheries or grazing land that were shared, used and enjoyed by all. Commons were then adapted to include public goods and services, such as public spaces, marketplaces, public education, health and infrastructure that allow societies to function. Today, with the proliferation of technology and in...
During the last two centuries, the urban percentage of the world's population, combined with the overall growth phenomenon, has deeply increased and it is projected to reach 60% by 2030. In this current context linked to environmental issues managing to plan sustainable cities appears a main policy target. The implementation of Zero Energy Buildings as a European target becomes a challenge for the...
Agent-based Modeling (ABM) has become quite popular to the simulation community for its usability and wide area of applicability. However, speed is not usually a trait that ABM tools are characterized of attaining. This paper presents HLogo, a parallel variant of the NetLogo ABM framework, that seeks to increase the performance of ABM by utilizing Software Transactional Memory and multi-core CPUs,...
