The bidirectional model transformation (BX) comprises a forward transformation get and a backward transformation put. Given that get may be an information-loss transformation, the behavior of put may be uncertain. An uncertain put produces many valid outputs that fit different application scenarios. This paper proposes an approach to variability management in BX to enable put to generate an output...
In this paper we present a novel software analytics infrastructure supporting for a combination of three requirements to serve software practitioners in utilising data-driven decision making: (1) Real-time insight: streaming software analytics unify static historical and current event-stream data enabling for immediate, nearly real-time insight into software quality, processes and users; (2) Query...
In this extended abstract, we briefly survey the vision and goals of On-The-Fly (OTF) computing. Then we turn to heterogeneous multi-cores which, as platforms for OTF computing scenarios, have to support a high dynamics in both the workload and the system state. We argue that concepts and models of self-awareness studied in, for example, psychology, have been successfully transferred to the computing...
The cooperative edition of (meta)models may be enacted by the exchange of change operation journals between the participants. But these are often composed of atomic operations (create, delete, set, …) that have no useful meaning for the users. Hence, detecting and recovering composite operations is a crucial step to help users understand the history of their (meta)models in terms of higher level operations...
Software architects who collaboratively evolve a software model rely on version control systems (VCSs) to synchronize their individual changes to the model. However, with the current generation of software model VCSs, architects remain unaware of newly arising conflicts until the next synchronization, raising the risk that delayed conflict resolution will be much harder. There are existing tools that...
Home-based rehabilitation has evolved in recent years as a cost-effective and convenient alternative to traditional clinical rehabilitation. This has consequently created the need to design reliable assessment and adaptation mechanisms that are able to measure and analyze the patient’s performance and to accordingly make proper adjustments that conform to the abilities of the patient during the training...
In today's rapidly changing business environment a company's business and related information systems underlie constant change. The field of evolutionary business information systems deals with applications that can be modified partially by stakeholders regarding content and behavior with the objective to align to new business requirements. A possibility to change the behavior of an application could...
Decision making for software project management encompasses a critical role for effective management. Decisions stem from constraints considered over definition of a project. Decision making of this practice considered with many challenges ranged based on intangible nature of software projects to the deficiency of strategy-model employed. In this paper a conceptual multi-method simulation based framework...
In this paper we illustrate a cost-effective software-in-the-loop simulation methodology, which is particularly suitable for testing large-scale pervasive systems and applications. The main advantage of such an approach is that real code has to be deployed once, and a general-purpose simulation engine replicates it over virtual devices and environments as often as we wish. Our implementation of the...
Software quality is the most important factor in the development of software, which can be depend on many quality attributes. One of the technique is Fuzzy Logic which can be used to establish the relationship between object oriented metrics and software maintainability. This paper presents the application of fuzzy logic in estimation of software maintainability. In this paper, a new model is proposed...
Engine Management System (EMS) is one of the most important and complex control systems in motor vehicles. The complexity of EMS strategies has recently increased even more in order to satisfy the more strict emissions legislations and safety standards. In order to cope with this challenge, Model Based Design is adopted. In this paper âEnvSimâ is proposed and developed as a framework for simulating...
Many games have computer-controlled agents that play against a player. The behavior of these computer-controlled agents is described by means of the artificial intelligence (AI) in the game. The AI is an important component of the game, and needs to be developed carefully, and adapted regularly. This paper introduces a novel language for describing the decision making process of the AI in real-time...
This paper presents my Ph.D. research that focuses on developing concepts and techniques for Model-Based Vulnerability Testing (MBVT) of Web Applications. This research bridges the gap between MBT techniques, which are usually addressed to functional testing, and vulnerability testing, which is mostly done manually or with the assistance of Web Vulnerability Scanners, both techniques having several...
Simulation games can help teaching and learning in several areas of Software Engineering. One important research issue is providing support for simulation games development, making the results of their adoption successful in Software Engineering courses. In this work, we identify a set of requirements focusing on some of the Constructivist learning theories. These requirements were used to evaluate...
In model-based software development, models are primary artifacts which iteratively evolve and which have many versions during their lifetime. A clear representation of the changes between different versions of a model is the key to understanding and successfully managing the evolution of a model-based system. However, model comparison tools currently available display model differences on a low level...
Identical domain concepts reified in different metamodelling projects may be named, represented and connected differently. It turns out that a transformation defined for a particular metamodel cannot be directly used for another metamodel. To tackle this problem, we propose a process for automatically adapting legacy transformations. Such a transformation is adapted to the new metamodel that has a...
We propose to use Artificial Intelligence techniques to monitor and control complex processing chains of software components. We consider software systems that run in an evolving environment and thus may require adaptation at run time. Our approach relies on knowledge representations of both structural and dynamic aspects of components and processing chains. The paper concentrates more precisely on...
Model-Driven Engineering (MDE) has become in the last years one of the most promising technologies for software productivity improvement. Much technology has been developed around MDE including editors, model transformation engines, constraint definition languages, etc. However, the impact of MDE in software companies is still not deep enough, often because existing tools and methods fail to adapt...
Workflows are a promising mean to increase the quality of modeling and simulation (M&S) products such as studies and models. In exploiting workflows for M&S, requirements arise that need to be reflected in the structure and components of a workflow supporting framework, such as WORMS (WORkflows for Modeling and Simulation). In WORMS, we adapt concepts of business process modeling and scientific...
