Pervasive computing envisions environments where computers are blended into everyday objects in order to provide added-value services to people. Already today, there is a growing number of advanced embedded systems around us, extended with computing and communication capabilities. However, pervasive applications raise major challenges in term of software engineering and remain hard to develop, deploy,...
In this paper, which describes a work in progress, we wish to propose context aware service delivery, and we focus on distributed human computer interface, in order to exploit the variety of interaction mode/capabilities according to current situation, users, and context. Our aim is providing new kind of more dynamic interaction modes. We particularly focus on the domain of smart-home (including digital...
Self-adaptive systems are able to modify their behavior and/or structure to deal with their continuously changing environment and internal dynamics. MAPE control loops, based on these four steps: Monitoring, Analysis, Planning, and Execution, have been identified as crucial elements in realizing self-adaptation of software systems. Adaptive systems are generally more difficult to design, specify and...
Information overload is one of the most important problems in context of personalized document retrieval systems. In this paper we propose to use ontology-based user profile. Ontological structures are appropriate to represent relations between concepts in user profile. We present a method for determining user profile based on his current activities. Results obtained in experimental evaluation are...
In this keynote talk we propose the use of a capability-driven approach to enterprise modeling in order to capture the intertwined relationship among design requirements and environment, as well as the interplay of requirements and design artifacts for the purpose of facilitating enterprise agility.
In this position paper, we present our interdisciplinary research into a unified account of profiling attackers for software-intensive systems. Our work draws on the principles from requirements engineering and criminology. Specifically, we show how a unified crime theory can be adapted to model the attackers and their degree of knowledge about the environment in which the software operates. We illustrate...
Human activity is almost always intentional. By understanding why user-generated events are happening and what purposes they serve, a system can offer a significantly improved and more engaging experience. Analyzing user actions such as clicks can reveal patterns and behaviors. However, understanding the goals behind these actions is a more challenging issue since goals cannot be easily captured....
Lifelong learning exists today in the context of a cultural and societal shift to a knowledge-based, technology-enhanced, and rapidly-changing economy. It has a significant impact on people's lives and has become of vital importance with the emergence of new technologies that change how people communicate, collect information, and collaborate with others. The emerging technologies, such as social...
Workflows are an established IT concept to achieve business goals in a reliable and robust manner. However, the dynamic nature of modern information systems, the upcoming Industry 4.0, and the Internet of Things increase the complexity of modeling robust workflows significantly as various kinds of situations, such as the failure of a production system, have to be considered explicitly. Consequently,...
Over several decades, a variety of studies have analysed analogical thinking as a cognitive mechanism, in which the individual transfers information from similar situations or problems and uses it to solve problems. However, less research is given that focuses on the use of predefined analogies as external stimuli for the ideation process. As a result, there has been very little information available...
Achieving a smooth flow of work through the system is a goal for many teams and organizations that embrace agile and lean approaches. However, the flow of work faces many impediments as it flows through teams and organizations. Agile and lean approaches can reveal impediments that impact teams and organizations. Often at the start of their agile transition, but also frequently after the initial transition,...
Existing work on pursuit-evasion problems typically either assumes stationary or heuristic behavior of one side and examines countermeasures of the other, or assumes both sides to be strategic which leads to a game theoretical framework. Results from the former may lack robustness against changes in the adversarial behavior, while those from the latter are often difficult to justify due to the implied...
The multiplication of large-scale document collections has created the need for robust and adaptive access strategies in many applicative areas. In this paper, we depart from the traditional document search paradigm to move onto the construction of a collection navigation strategy. We thus detail a model where user clicks are taken as expression of interest rather than positive search feedback. In...
This paper is a pilot study for a combination of school knowledge and board game learning. We designed a digital board game based on textbook materials. And presented them with a set of educational equipment- Digital Learning Playground (DLP). We created a situational interaction learning in classrooms. In this research, the resulted data indicates the students¡¦ motivation, confidence and satisfaction...
This paper presents a situation-based service composition model for dynamic environments in which the characteristics of the surrounding environments are frequently changing. The main contribution of situation-based service composition model is: (1) to provide a concept of situations which specified the mutual affects of situated conditions and situated services, and (2) to provide an adaptation mechanism...
As wireless sensor nodes are mostly battery-powered, energy-efficient operation is a necessity to use their confined energy budget optimally. This is especially true in the logistics domain, where timely and accurate monitoring of containers is required, while the cost pressure is high. Thus, besides the need for energy efficiency, wireless sensor network deployments in logistics require cost efficiency...
The assessment process is one of the most important issues in the learning process and in many case it is the process that defines the instruction sequence because it measures the performance of the student in the educational process. During recent decades the inclusion of TICs in the teaching-learning process have facilitated addressing the diversity of student and teacher features. Technologies...
Recent years witnessed an ever growing impact of trust in the decision-making process within virtual communities. The inherent decentralized and open nature of such environments produced new challenges that received, up to now, little attention. For example, the individual and collective trust co-influence remains an unexplored issue. In this paper we are considering how user-centred and community-centred...
