We have created and implemented an ontological model, which addresses the problem of data sharing and interoperability in a heterogeneous hospital computing environment. We have also used semantic web tools and reasoning mechanisms to achieve our aims and have demonstrated that it is feasible to share heterogeneous data across hospital environments and create an intelligent awareness for software applications built within them.

Smart Rooms integrated with sensors, actuators, wireless networks and context-aware applications will soon become part of our daily life. To build successful context-aware systems, we must develop an architecture to reduce the difficulty and cost of building these systems. This paper presents the architecture of ChaturKartha, developed to setup a context aware intelligent Room. Based on the gathered contextual knowledge, ChaturKartha infer what the users expect and accordingly delivers the expected services. Our architecture explores the use of Semantic Web languages for defining context ontology and for reasoning over such information.

The services are generally used in distributedcomputing platforms called "Grid Services" that combines the Grid technology with the web service concept. In the Grid computing environment, several services are crucial. When these services fail, the computing can be terminated. The service reliability is a requirement of the system. Thus, we proposed to a prototype of reliable service model based on resiliency replication that uses forward recovery concepts. We study on the model's performance and its reliability and constructed an experiment to prove our analysis with the measured value. The results presented that the model predicted the performance very close from the actual value.

Cryptosystem based on Lucas Function is known as LUC Cryptosystems. Lucas Function is a special form of second order linear recurrence relation using a large public integer as a modulus. We are sure that, an existing computation technique will suffer a huge computations time and spaces when calculating a very large size of public-key and private-key. Recently, a method for fast LUC Cryptosystems computation on single processor has been proposed. In this paper, we extend the method in parallel on distributed memory multiprocessor machine using message-passing interface. We are generating a special sequence from a given value of public-key and private-key. This special sequence will be used to direct the computation of LUC. We examine the parallelism efficiency of the algorithm by analyze the simulation time and speedup.

Ubiquitous computing paradigm involves handling physical spaces having abundance of computing devices, with variety of resources, capabilities, services and policies. The physical and logical work environment created with ubiquitous computing characteristics can be termed as smart space. It will assist user in performing his tasks without bothering about intricacies of handling or configuring the devices and applications programs. Such tasks of configuring are handled unobtrusively by the smart space itself. Most of the design efforts for smart space have been centred on development of new middleware for creation of the ubiquitous environment. This paper presents an operating system based design of a software infrastructure for a campus-wide smart space. A mapping of the proposed design to a use-case scenario is also presented.

This paper presents a new efficient data-exchange process in parallel sorting, which improves both communication time and memory space. In this communication-space efficient strategy, we proposed two new parallel sorting algorithms: 1) CSEBS (Communication-Space Efficient Bitonic Sort) algorithm and 2) CSEOE (Communication-Space Efficient Odd-Even MergeSort) algorithm. In addition, to evaluate the performance, we have implemented the CSEBS and the CSEOE algorithms on the SGI Origin2000. Investigated experimental results have been compared to those of the best of existing algorithm (CEBS: Communication Efficient Bitonic Sort). In the experiments, the proposed CSEBS algorithm yielded the improved results over those of the best of existing algorithm (CEBS) at least 11% on the system of size P = 4 and at least 31% on the system of size P = 8. Moreover our approach can save memory space up to 50%.

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.

Regression testing is essential in ensuring continuous improvement of the quality and confidence of every subsequent release of software-products (or long-running projects). However, the (time and man-power) cost of using the entire regression test suite for minor modifications or bug-fixes is often prohibitively high, whereas, the risk associated with releasing a regressed (new) version of the product is not acceptable, either. In this paper we present a technique to identify a small safe subset regression-test-suite for object-oriented managedcode that selects the set of all relevant tests, given the previous and the current versions of the implementation binaries. We have developed ChiARTS, a prototype implementation of our technique for the C# Language, and also overseen its smooth introduction into the test process for a large (internal) software product-line under Philips Medical systems. The design of ChiARTS caters to the needs of our industry-strength test-harness for multi-threaded tests.
