Abstract– In this paper, improvement of performance the unguided nonlinear optical laser pulses propagate in an inhomogeneous static pure water and clearest sea water with soliton technique is deeply and parametrically studied. The interaction of such powerful optical laser pulses and the waters has been investigated over wide ranges of the affecting parameters through model taking into account the coupling of the waters and the optical laser pulses along the propagation path through a special numerical technique and a special designed software. The physical parameters of the waters are considered both temperature dependent and spectral-dependent parameters as well as salinity-dependent. The obtained types of solutions are valuable in obtaining a physical feel for the problem and obtaining an order-of-magnitude estimate of the severity of the effects of the controlling parameters. Study the stabilities of the product of power and square of the pulse width, pulse width, and transmitted bit-rate are analyzed on the basis of the thermal sensitivity for the sea water.

Abstract– Multi-agent systems (MAS) simplify human life with automated functioning. This approach has also been implemented for remote patient monitoring (RPM). The objective of this paper is to find weaknesses in existing technology and to contribute to enhance the system with mature functioning. To achieve a robust system, we propose the optimized nomadic devices based RPM framework. Finally, we demonstrate the prototype system developed on our proposed framework. Our RPM system outperforms to the existing ones.

Abstract– This research was developed to produce a prototype product of a Web Based Temperature Monitoring system that allows the user to continuously monitor the temperature condition of a room. The enhancement from the existing system on the temperature monitoring is that this prototype system allowed the data to be monitored anytime and anywhere from the Internet. This research development project was divided into two parts that involved with the hardware and software. The hardware part involved building the temperature sensor board and for the software part involved written programming and construct coding using C language program. The programs then are uploaded into the microcontroller which then created Visual Basic 6.0 application to display the temperature and saves the data into a database. An active Server Page (ASP) scripting language is used as server side scripting to publish the current temperature at the web browser. This prototype of a Web-Based Temperature Monitoring has met all the objectives derived and planned. The research project is considered successful and ready to be launched in the real system implementations.

Abstract– The growth of web applications and the user needs over the internet generate the problems of relevant interactions among web applications as well as among users and applications. These types of problem have been tried to resolve using web services in addition to service oriented architecture and enterprise applications. However, it is very difficult to find an appropriate web service which satisfies user needs. The user wants an efficient way to find an appropriate web service which satisfied its needs in short time. In this paper we describe an efficient strategy to find web service by combining two strategies including input parameter search and synonym based search.

Abstract– As we approach towards physical limits of processor and memory speed it is difficult for a single computer system to handle ever increasing demand of processing and memory requirements of modern applications of these days. To overcome this problem distributed systems are useful where multiple computers interact through shared memory to achieve a common goal through concurrent programming. Concurrent programming results the most efficient use of resources but it’s difficult to handle and results many concurrency and synchronization problems. Several algorithms have been developed to solve above problems and are being continuously developed based on importance of the problem in computer science. We present a comparative analysis of different concurrency control algorithms based on parameters like mutual exclusion, deadlock freedom, starvation freedom, first in first out fairness and local spinning. This helps the reader to understand nature of these algorithms and utilize any of the algorithms that best suits to his/her requirements.

Traditional search to Semantic Search

Abstract– The most popular search technique being used in semantic models is Spreading Activation. When ontology is given in the form of a semantic model, based on the certain properties of the ontology instances, weights are assigned to the relations between instances to indicate how related two particular concepts are. The key concept behind Spreading Activation technique is to find related concepts in the semantic model, given an initial set of concepts and their activation values. These initial values are first calculated by traditional search applied on the data that is associated with the instances in the ontology. Applying both traditional and spreading activation searches combined will give better results compared to applying alone. In this paper, we go through the traditional search techniques and combine them with techniques for semantic models to get better semantic results.
