Component-based software engineering (CBSE) has become a commonly used development technique. Using it, applications are composed of reusable components with well defined interfaces and behavior. Currently, in the scope of CBSE, research has been driven in huge number of directions and by many research teams. Naturally, such conditions are ideal for mutual cooperation and collaboration. In this paper, we describe our experience with research cooperation, especially in the scope of Europe. We present experience gained during recent joint projects, in which we have participated. Also, we present our research areas and topics and ongoing work on them. Copyright 2008 ACM.

Wireless mesh networks are a special kind of ad hoc networks in which most nodes are static. The application purpose of wireless mesh networks is also different than that of ad hoc networks and is focused on broadband access services to the Internet. Recent studies have shown that nodes in a wireless mesh network have to be equipped with several radio interfaces for high performance. However, one of the challenges that still faces high performance wireless mesh networks is the capacity reduction due to interference of wireless links. In this paper, we address the problem of assigning channels to nodes in wireless mesh networks. For this, we propose and study the cluster channel assignment (CCA) approach with the goal of reducing the network interference to increase the overall network performance.
This paper introduces a novel concept for automated navigation and control of a mobile platform. It utilizes an ad-hoc mobile wireless sensor network to provide navigational information to the mobile platform embedded...

Wireless mesh networks (WMNs) are an emerging technology which provides broadband wireless access services. One of the challenges that still faces high performance WMNs is the capacity reduction due to interference of wireless links. In this paper, we address the problem of assigning channels to nodes in WMNs. For this, we introduce the cluster channel assignment (CCA) approach with the objective of reducing network interference to increase the overall network performance. A clustering approach is employed in order to reduce the complexity of channel assignment into local problems within clusters and taking the advantage of the possibility to reuse the channels in different clusters.

Today's software systems are mostly modular and have to be changeable. However, the testing of such systems becomes difficult, especially when changes are applied after deployment. One way to passively test such a system is to check whether the observed traces are accepted by a system model. In this paper, we present a method to generate a model of the System Under Test from its test cases. We adapt Angluin's algorithm for learning finite automata to the special case of learning from traces obtained from test cases and provide the promising results of our experiment.
The increased usage of Web services for critical applications introduces a growing need for efficient testing approaches to assure their quality. The Testing and Test Control Notation (TTCN-3) is a standardised testin...

Determine the appropriate loop transformations is an essential process in the automatic parallelization field. The sequence of loop transformation to be applied also must be considered. Selection of loop transformations faces many challenges, it is needed an experienced. In this paper, An Intelligent Loop Transformation Selector (ILTS);as a part of parallelizing tool project, was developed to overcome on these challenges and imitate an experienced. A Kohonen's Self-Organizing Map (SOM) neural network is used to select the appropriate loop transformation or sequence of them. Neural Networks offer intelligent transformations selection to reduce or eliminate the dependencies and maximize the parallelization in the sequential code. The experimental results show that ILTS chooses loop transformations successfully in most cases. This tool can be integrated with any parallelizing compiler to enhance loop transformation selection process.
At system level, the on-chip temperature depends both on power density and the thermal coupling with the neighboring regions. The problem of finding the right set of input power profile(s) for accurate temperature est...
