Abstract: This paper addresses design, hardware implementation and performance testing of AES algorithm. An optimized code for the Rijndael algorithm with 128-bit keys has been developed. The area and throughput are carefully trading off to make it suitable for wireless military communication and mobile...     Read More

Abstract: Very often computation of multiple group -bys are done by OLAP applications. Many of the OLAP applications use cube operator. The cube operator requires computing group-bys on all possible combinations of list of attributes. If multiple copies of the same data are stored at different data bases ...     Read More

Abstract: People use cryptography to send secret messages to one another without a third party overseeing the message. Steganography is a type of cryptography in which the secret message is hidden in another message. In this paper, a method of hiding the speech signal inside a music file using LSB coding ...     Read More

Abstract: Data Mining is one of the eminent research fields to find interesting trends or patterns in large datasets. In order to work with the numeric or categorical data, the classification technique suits well for analyzing and processing for wider variety of large databases. Efficiency and scalability...     Read More

Abstract: In this paper we extend the single server interdependent queuing models to bulk service queueing models. Here we consider the costumers/units served a batch of k at a time and if not, the server waits until such time to start. In this model various system characteristics like average queue length,...     Read More

Abstract: In this paper , a new method for image compression based on adaptive quantization using set of selected bit planes is being proposed .This technique combines adaptive quantization with an additional unit, with the aim of checking the intensity variation of each image block, and selects bit plane...     Read More

Abstract: IN traditional cancer diagnosis, pathologists examine biopsies to make diagnostic assessments largely based on cell morphology and tissue distribution. However, this is subjective and often leads to considerable variability. On the other hand, computational diagnostic tools enable objective judg...     Read More

Abstract: According to the Euronet mobile Banking Guide, there are currently close to 400 Mobile Operators in over 133 countries who are signing up 4 to 6 new customers every second. This implies that more people are going mobile like never before. The novel method presented in this paper is an Interacti...     Read More

Abstract: In wireless sensor networks (WSNs), data aggregation techniques are used to collect the data sample at sink through the cluster head, generated by sensor nodes. Data aggregation for WSNs must address to the issues of WSNs like limited energy in battery powered sensor, and fast and efficient quer...     Read More

Abstract: The optimal capacitor placement problem involves determination of the location, number, type and sizes of capacitor to be placed in a distribution system in the most efficient manner. The main objective of optimal capacitor allocation is to reduce the peak power losses of the system while striv...     Read More
