With todays wide acceptance of distributed computing, a rapidly growing number of application domains are emerging, leading to a growing number of ad-hoc solutions, rigid and poorly interoperable. Our response to this challenge is a platform for building flexible and interoperable execution environments (including language and system aspects) called the Virtual Virtual Machine. This paper prese...

The necessity of complex-shaped components characterized by superior mechanical properties and limited weight is moving the attention to Aluminium (Al) alloys. Deep Drawing Steel grades possess stamping characteristics formability with respect Al But need light-weighting pushes towards adoption materials optimal strenght-to-weight ratio, like Todays alloys are certainly used in transport sector...

A major challenge in todays fast pace world is the acquisition of competence in a timely and efficient manner, whilst keeping the individual highly motivated. This paper presents a novel based on the use of serious games driven by Case Based Reasoning (CBR) tailored by Threshold Concepts (TC) to present the learner with the most efficient choice of game scenarios to address their present compet...

Constraint Propagation can be speeded up significantly by choosing a good execution order for propagators. A propagator is an implicit representation of a constraint which is widely used in todays powerful constraint solvers. In this paper we evaluate different ways to find good execution orders automatically during runtime. We extend previous work in this area by two new techniques: fair-sched...

As mobility permeates into todays computing and communication arena, we envision application infrastructures that will increasingly rely on mobile technologies. Traditional database applications and information service applications will need to integrate mobile entities: people and computers. In this paper, we develop a distributed database framework for mobile environments. A key requirement i...

Malicious web sites perform drive-by download attacks to infect their visitors with malware. Current protection approaches rely on blackor whitelisting techniques that are difficult to keep up-to-date. As todays drive-by attacks already employ encryption to evade network level detection we propose a series of techniques that can be implemented in web browsers to protect the user from such threa...

One of the most important areas of a network intrusion detection system (NIDS), stateful inspection, is described in this paper. We present a novel reconfigurable hardware architecture implementing TCP stateful inspection used in NIDS. This is to achieve a more efficient and faster network intrusion detection system as todays’ NIDSs show inefficiency and even fail to perform while encountering ...

Ambient Assisted Living (AAL) systems are a relatively new and expanding area of research. Due to current demographic trends towards gentrification of the population AAL systems are bound to become more important in todays and near future’s societies. Fall detection is an important component of AAL systems which could provide better safety and higher independency of the elderly. This paper pres...

Recently, approaches that combine contexts and ontologies taking advantages of their strengths have been developed. Each of them solves different problems from different perspectives. The objective of this paper is to present problems that are not solved up to date as well as to introduce a conceptual proposal. To this aim, we base our analysis on a collaborative B2B scenario that is relevant f...
