Abstract -
Content oriented networks have been proposed as a new network architecture that does not rely on IP addresses. n these networks, content queries are routed based on the content name itself instead of a destination address. However, one problem that occurs with content oriented networks is the increased memory usage. This is because a huge amount of content exists in the network, and an entry is created in the routing table for each content item. One technique to address this problem is a routing scheme using Bloom filters, which are data structures capable of compressing data. However, this technique cannot cope with content that is moved or deleted. To solve this problem, we propose a method that can cope with moved or deleted content by using two Bloom filters. Simulations we conducted to evaluate the proposed scheme indicated the method was more effective than conventional schemes.

Abstract -
Globally, research is an important activity in any educational and industrial establishment. In education, research provides the opportunity for knowledge discovery as well as important solutions to scientific problems. In order to make research an important gateway to education, tertiary institutions have to employ innovative strategies and procedures. This paves the way for effective and efficient education, which benefits a country as a whole. Nevertheless, in developing countries, the progress of research in educational establishments is relatively slow in comparison to institutions of higher learning in developed countries. Factors such as appropriate research environments, electronic library (e-library) support and access to important/top journal and conference articles hinder research progress. With a focus on computer science research, this paper discusses how to enhance research in polytechnic education. Specifically, the paper discusses the problems associated with computer science research in Accra Polytechnic, Ghana and suggests methods and recommendations that can be used to improve these problems in order to achieve effective productivity and sustainability.

Abstract -
Knowledge is one of the fundamental key to development. The ability to convert knowledge base to practical solution is hitherto even more desirable and sorted, because of its effectiveness in world development. Practical knowledge acquisition through internet technology, presents to the world especially developing ones, the secret source of real solution to national development issues, which is usually underestimated or simply neglected due to ignorance or negative technology perception. It examined the importance of its effective application to education system of the nation especially from the secondary stage, which it considers as the grassroots level. Furthermore, it analysed traditional bottlenecks militating against its actual integration and suggested solutions to these hindrances and emphatically specified the reason why the bull must be taken by the horn, using personal life experience and examples. It also identified further research targets to strengthen its need assessment base.

Abstract -
Cloud computing refers to the Internet based development and utilization of computer technology, and hence, cloud computing can be described as a model of Internet-based computing. The primary aim of cloud computing is to provide efficient access to remote and geographically distributed resources. Load balancing is the major concern in the cloud computing environment. Cloud comprises of many hardware and software resources and managing these will play an important role in executing a client's request. In this present situation the load balancing algorithms built should be very efficient in allocating the request and also ensuring the usage of the resources in an intelligent way so that underutilization and overutilization of the resources will not occur in the cloud environment. The main goal of scheduling is to maximize the resource utilization i.e. energy reduction, power management and minimize processing time of the tasks using migration. In this research paper we present a generalized hybrid algorithm for efficient execution of tasks and comparison with earlier algorithm for optimization, FCFS and priority scheduling. We have specifically focused on improving computational cloud performance in terms of total processing time, power management and energy consumption. A simulation of proposed approach on Windows Azure platform has been conducted. Experimental results show that proposed algorithm performs efficiently. Results are compared with existing resource management algorithms in computational cloud environment.
