Data migration has become a priority in many industries, spawned by a variety of business needs. Most of the existing tools for Extract, Transform and Load (ETL) process of data migration are piece-meal and do not present a complete solution. Moreover, while research has focused on the problem of Schema Mapping, a key step in the ETL process, most of the(More)
Face is a complex multidimensional visual model and developing a computational model for face recognition is difficult. The paper presents a methodology for face recognition based on information theory approach of coding and decoding the face image. Proposed methodology is connection of two stages – Feature extraction using principle component(More)
This paper addresses the problem of retrieval from graph databases. Graph databases store graph structures instead of tables. Typically, graph databases are applicable in domains that require storage and retrieval of structural information. One of the main issues in graph databases is retrieval of member graphs based on structure matching. Structure(More)
Wireless Sensor Networks need energy efficient protocol for carrying out various operations. Cooperation among nodes may save significant energy by avoiding retransmission from distant nodes. In this work, a new scheme has been suggested for LEACH based WSN by introducing cooperation among various cluster heads. Significant improvement in BER has been(More)
In this paper, we propose a simple video summarization system based on removal of similar frames and the maintenance of unique frames. It tries to capture the temporal content of the frame and to output the video with a length specified by the user. It aims at eliminating similar frames by a process of clustering where similar frames are clustered into one(More)
Next generation Internet applications provide guaranteed end-to-end quality-of-service (QoS). Optimization based on constraints for QoS routing is computationally complex and for this reason many heuristics have been proposed for routing in a practical situation. Among these delay constrained least cost (DCLC) routing is popular. In this paper we propose an(More)
In this paper we present the PC cluster built at R.V. College of Engineering (with great help from the Department of Computer Science and Engineering). The structure of the cluster is described and the performance is evaluated by rendering of complex 3D Per-sistance of Vision(POV) images by the Ray-Tracing algorithm. Here, we propose an unexampled method to(More)
—Cognitive Network is a technique which is used to improve the spectrum utilization. Current network scenario is experiencing the huge spectrum scarcity problem due to the fixed assignment policy so in this method great amount of spectrum remain unused. To overcome this limitation the spectrum allocation must be in dynamic manner. In this paper the spectrum(More)
