Development of College of Industrial Technology FM Broadcast Trainer

An FM Broadcast Trainer was developed to expose the students to the basic equipment needed in radio broadcasting. The cost of Portable FM Broadcast Trainer is much lower than the cost of the traditional commercial equipment because of the materials used. The FM Broadcast Trainer is laboratory equipment that can be used by schools offering academic programs in Industrial Courses specifically Electronics Communication courses. At present there is no portable FM broadcast station available in the local market. Some schools are reluctant to by new FM station equipment since these are quite costly. To resolve this problem, the researchers deemed it necessary to design and develop a portable FM Broadcast Trainer that is simple and affordable to fulfil the basic curricular requirements for offering courses in Electronics Communication Technicians. This is a requirement for our graduates to qualify to take the Radio Telephone Operator examination given by the National Telecommunication Commission the telecommunication body in the Philippines counterpart of Federal Communication Commission in the US. Aside from this, the station will be a venue for Mass Communications students and a vehicle for channelling important announcement from the School.

An Efficient Clustering of Wireless Sensor Network by Spectral Graph Partitioning

The past decade has observed the development of wireless sensor networks (WSNs) being used in a great number of applications. For the better routing and energy efficiency, WSNs are partitioned into clusters. Partitioning was done to minimize the distances between the source node and the sink. In order to achieve better partitioning, graph partitioning methods can be used. Such techniques are mostly used in distributed environment and applications, but they are not much efficient in wireless sensor networks due to the dynamic topology and multi-hop transmission. In this paper, few existing graph partitioning methods have been discussed and studied which may be implemented for WSN partitioning. A novel partitioning method is tested in this paper, which is better in terms of efficiency in WSN partitioning.
