In this paper, the authors design a file security function on Windows O.S (Operating System). Whenever users use Windows O.S, they need to protect some file data. This paper designs these security protection functions. This paper proposes two security functions on Windows O.S. One is file security. The other is directory access protection. To check ...

Clustering is important data mining technique to extract useful information from various high dimensional datasets. A wide range of clustering algorithms is available in literature and still an open area for researcher. K-means algorithm is one of the basic and most simple partitioning clustering technique is given by the researchers and aim of this clustering ...

Data intensive applications that rely heavily on huge databases waste a lot of time in searching and retrieval especially if there is a single server retrieving data from the database. This paper proposes a Beowulf cluster for fast query processing by distributing the database horizontally over nodes through a load balancing act. A mathematical model ...

In this paper, the authors conducted an experiment to show the impact of overclocking the CPU (Central Processing Unit) to the genetic algorithm. For the CPU part, they have used Intel core 2 duo E6420, its original frequency is 2.13 GHz, and they have succeeded to hit 3.20 GHz which is about 50% boost. For ...

In this paper, the authors present an efficient VLSI (Very-Large-Scale Integration) architecture of a high speed, low power 2-D Discrete Wavelet Transform computing. The proposed architecture, based on new and fast lifting scheme approach for (9, 7) filter in DWT, reduces the hardware complexity and memory accesses. Moreover, it has the ability of performing progressive ...

The demand for high speed wireless data communication has been increasing tremendously. Wireless applications typically require VCO’s (Voltage Controlled Oscillator’s) having low power consumption, low phase noise, small size and low cost. The size, the cost requirements and the low phase noise make an integrated oscillator in a standard CMOS (Complementary Metal-Oxide-Semiconductor) process with an ...

In this paper, the authors present their experiences of building Linux/RTOS (Real-Time Operating System) hybrid operating environments on Xen and Gandalf Virtual Machine Monitors (VMMs). Xen is a popular open source VMM while Gandalf is their in-house virtual machine monitor that was designed and implemented from scratch to be a simple yet extremely lightweight VMM. ...
