Preprocessing is an important step in Web usage mining. Web log files are the great source of knowledge which can be used to analyze behavior of online users. Data cleaning, user identification and session identification are involved in data preprocessing. The time spent by user on the web page is considered for calculating session. There ...

Comparator is the basic module in digital system. It is widely used in communication and calculation areas. This paper is to provide new low power, area solution for Very Large Scale Integration (VLSI) designers. The authors can design the circuits at gate level as well as transistor level but designing the circuits at gate level ...

A biometric system is a pattern recognition system that recognizes a person on the basis of the physiological or behavioral characteristics that the person possesses. There is increasing interest of researchers in the development of fast and accurate personal recognition systems. In this paper, the authors are using palmprint for authentication, because it is having ...

Bluetooth is an open specification for short-range wireless communication and networking, mainly intended to be a cable replacement between portable and/or fixed electronic devices. The main aim of introducing Bluetooth is to connect two or more devices without any physical connection. This helps to reduce time and human efforts for transferring data. The specification also ...

The authors find the problem of privacy preserving back propagation algorithm for a vertically partitioned dataset. To improve the learning, enhanced data is more important to find the exact privacy concern of each data holder by extending the privacy preservation suggested to original learning algorithms. In this paper, they try to improve preserving the privacy ...

Now-a-days wireless technologies are important in the world of communication due to its mobility, bandwidth & low cost. But as numbers of nodes are increases network complexity & bit error rate increases this lowers the transmission rate. This paper aims at performance evaluation of routing algorithms for ad hoc network for video signal transmission. It ...

Wireless sensor networks are a special category of ad hoc wireless networks that are used to provide a wireless communication infrastructure among the sensor deployed in a specific application domain. Wireless sensor and actor network consist of more number of sensor and actor, linked by the wireless medium to perform timely action for the given ...

Wireless Sensor Networks (WSN) is tiny independent devices enclosed firmly in surrounding nodes, able to communicate using wireless links. A wireless sensor network holds huge number of nodes they are spread in antagonistic and nodes are unattended. So, they are easily tracked by the adversary with no protection. An opponent can hold and compromise some ...

In this paper, the authors controlled the robot system in a new economical solution and as well as it is used for different sophisticated robot application. The control system consists of touch screen and Zigbee modules, a microcontroller that collects and controls the robot. Now spying area in military ground where enemy stay can be ...

The indexing technique for fuzzy Object Oriented Database (OOD) model is the extension towards database models to support complex data and to handle fuzziness in the complex database along with indexing to speed up the evaluation of fuzzy queries. In today’s era as traditional commercial market is changing rapidly towards specialized market where need of ...
