This paper presents a model-based engineering approach used for the development of a software architecture tailored for the special requirements of parallel kinematic machines. Several quality assurance measures that became possible by this approach and their application within an interdisciplinary research project are described in detail. Concepts for the integration of self-managed components and autonomic computing features are outlined
LC/MS is a successful analysis technique for the statistical analysis used in several branches of biology. It requires an intense screening and combination of the raw data, which is usually done with programs and libr...

The modelling of the educational processes and their operational support is a key aspect in the construction of more effective e-learning applications. Instructional models are usually described by means of an educational modelling language (EML). The EML used can be one of the available standards (e.g. IMS Learning Design), the customization of a standard to meet a specific application profile, or even a domain-specific EML specifically designed to best fit in the very particular needs of a learning scenario. In this paper we propose , a general authoring and operationalization architecture capable of dealing with all these possibilities in a highly modular and flexible way. We also outline a specific implementation of based on standard XML technologies and in the BPEL4WS workflow management language, and we describe how this implementation can be used to support IMS Learning Design.
In this paper the improvement in the performance obtained by a Time Interleaving applied to DVB-T scheme are analyzed in impulsive noise environments. The performance is evaluated in terms of bit error rate probabilit...

This paper presents an advanced control structure exploiting a GPC master-slave solution to regulate the oxygen and nitrification process of a simulated water treatment plant. The slave controller regulates the process variable, whilst the master controller changes the set-point for the slave controller depending on the output behaviour of the system. The presented structure outperforms significantly the standard control structure. Different weather conditions are simulated and analysed for comparison
Crosscutting concerns are pervasive in embedded software, because of the various constraints imposed by the environment and the stringent QoS requirements on the system. This paper presents a framework for modularizin...

Today Web-based applications are very complex and provide several hundred users with access to sensible data. Adequate access control mechanisms that prevent unauthorized access and gives policy-compliant access to users depending on their status are thus central. The online conference service (OCS) is a system of services which collectively provide all necessary workflows and functionalities an online decision support service needs. Here we describe its flexible role-based access control mechanism and introduce the embedded role management service, which is extensible, modifiable and reconfigurable online, during the service operations. We also discuss a first version of the personalized role management service as used in the OJS, the journal member of the product line initiated by the OCS

This work presents the performance of WLAN and MANET networks using the auto-configuration of Mobile IP Agents Protocol (DRMIPA). This scheme would allow groups of MIP nodes in WLANs or MANETs to enjoy IP mobility at any foreign or local network that doesn't implement MIP. To maintain a failure free MIP network, a passive agent is elected from an active agent if this active agent leaves or ceases its participation from current network. The DRMIPA protocol is implemented in WLAN and MANET. A performance analysis is done using a real world testbed scenario.

Our approach to the model-driven collaborative design of workflows for bioinformatic applications uses the jABC for model driven mediation and choreography to complement a Web service-based elementary service provision. jABC is a framework for service development based on lightweight process coordination. Users (product developers and system/software designers) develop services and applications by composing reusable building-blocks into (flow-)graph structures that can be animated, analyzed, simulated, verified, executed, and compiled. This way of handling the collaborative design of complex processes has proven to be effective and adequate for the cooperation of non-programmers (in this case biologists) and technical people, and it is now being rolled out in the operative practice

This work presents a Dynamic Reconfiguration of Mobile IP Agents (DRMIPA) and failure free architecture integrated with Mobile Ad hoc Networks (MANETs). Actual infra-structured networks do not implement the Mobile IP (MIP) protocol, all MIP agents are static and the cost of having redundancy of MIP agents is often high. We propose a solution that would allow the integration of MIP with MANET. Therefore, new algorithms and messages are presented for DRMIPA in MANET and, a performance analysis is done using the Network Simulator 2 (NS2) and a real world testbed scenario.
