advances in Systems, computing Sciences and Software Engineering This book includes the proceedings of the International Conference on Systems, computing Sciences and Software Engineering (SCSS’05). The proceedings are a set of rigorously reviewed world-class manuscripts addressing and detailing state-of-the-art research projects in the areas of computer science, software engineering, computer engineering, systems sciences and engineering, information technology, parallel and distributedcomputing and web-based programming. SCSS’05 was part of the International Joint Conferences on Computer, Information, and Systems Sciences, and Engineering (CISSE’05) (www. cisse2005. org), the World’s first Engineering/computing and Systems Research E-Conference. CISSE’05 was the first high-caliber Research Conference in the world to be completely conducted online in real-time via the internet. CISSE’05 received 255 research paper submissions and the final program included 140 accepted papers, from more than 45 countries. The concept and format of CISSE’05 were very exciting and ground-breaking. The PowerPoint presentations, final paper manuscripts and time schedule for live presentations over the web had been available for 3 weeks prior to the start of the conference for all registrants, so they could choose the presentations they want to attend and think about questions that they might want to ask. The live audio presentations were also recorded and were part of the permanent CISSE archive, which also included all power point presentations and papers. SCSS’05 provided a virtual forum for presentation and discussion of the state-of the-art research on Systems, computing Sciences and Software Engineering.

Service-oriented architecture (SOA) is a popular industry standard that provides an elegant model to create and compose interoperable applications. In the case of sensor networks, SOA is considered to be a very attractive enabler for sensor programmability and self-integration. However, SOA cannot be used without additional mechanisms to enhance the reliability and availability of the sensors behind the services. In the absence of such mechanisms, sensor-based SOA could provide a false promise of service whose, quality and availability are highly questionable and cannot be guaranteed. In this paper, we propose a Virtual Sensor framework for service-oriented sensor networks with the aim of enhancing reliability, prolonging availability and enabling automatic service composability. We classify and model three useful virtual sensor concepts and present compensation algorithms for coping with sensor failure. To quantify the merit of our approach, we developed a Data Quality Indicator measure for expressing the perceived quality of virtual sensor readings.

A number of DNA computing models to solve mathematical graph problem such as the Hamiltonian Path Problem (HPP), Traveling Salesman Problem (TSP), and the Shortest Path Problem (SPP) have been proposed and demonstrated. Normally, the DNA sequences used for the computation should be critically designed in order to reduce error that could occur during computation. In 2007, we proposed a DNA computing readout method tailored specifically to HPP in DNA computing using real-time Polymerase Chain Reaction (PCR). We also proposed a procedure for DNA sequence design for DNA computation with output visualization on real-time PCR machine. The procedure includes DNASequenceGenerator which generate all the required sequences implemented in the experiment. In this paper, we propose different procedures by using generate-andtest algorithm with several design constraints to get all the DNA sequences. The generated DNA sequences represent nodes, edges, primers, and probes that are used in DNA computation of HPP with output visualization based on real-time PCR.

In many systems, backward recovery constitutes a classical technique to ensure fault-tolerance. It consists in restoring a computation in a consistent global state, saved in a global checkpoint, from which this computation can be resumed. A global checkpoint includes a set of local checkpoints, one from each process which correspond to local states dumped onto stable storage. In this paper we are interested in defining formally the domino effect for shared memory systems be the shared memory a physical one (as in multiprocessor systems) or a virtual one (as in distributed shared memory systems) and in designing a domino-free adaptive algorithm. These results lie on a necessary and sufficient condition which shows when a set of local checkpoints can belong to some consistent global checkpoint.
