Abstract: A nonlinear robot plant that incorporates robot manipulator dynamics as well as implementation of observer to estimate unmeasured states is proposed in this paper. The robot manipulator operates in the robot task space in lifting the object at a defined place and at a specified angle. Computer simul...     Read More

Abstract: Testing plays an important role in software development life cycle. Software testing is a critical element in software quality assurance and represents the ultimate review of specifications, design and coding. It is in general a laborious, costly and time consuming task: it spends almost 50% of soft...     Read More

Abstract: Games are becoming more popular as a tool for training, due to their promise of increased motivation, context-sensitive presentation of information, immediate feedback and increased sense of immersion. This kind of training should provide proper balance between being fun and engaging, and being info...     Read More

Abstract: With the wide application of ARM technology, design an interface between ARM and USB-OTG controller which can be used in mobile communication field, PDA, mobile phone and other mobile devices that can exchange data with USB peripherals directly with or without an interaction of PC. Interfacing requi...     Read More

Abstract: Image compression is the reduction or elimination of redundancy in image data representation in order to achieve savings in storage and communication. In this paper we propose a method for image compression and decompression using nested IFFT and FFT which works on both color and grey images. This t...     Read More

Abstract: Haptics is the science of applying touch (tactile) sensation and control to interact with computer applications. The word is derived from the Greek word “haptein” meaning “to fasten.” Organizations worldwide are using techniques and technologies to better manage their knowledge. Their object...     Read More

Abstract: The paper presents an issue of updating methods of commanding personnel’s training course on commanding police operations by means of simulator of police activities in crisis. With regard to fundamental forms of simulations used in armed forces’ combat operations, the article describes a prototy...     Read More

Abstract: A firewall is a security guard placed at the point of entry between a private network and the outside Internet such that all incoming and outgoing packets have to pass through it. The function of a firewall is to examine every incoming or outgoing packet. Here the paper aims to implement ACO (ant co...     Read More

Abstract: In E-society IT risk management has become both prudent practice and, in many cases, a legal necessity to protect the organization and its ability to perform their mission, not just its IT assets with respect to the cost. In this paper we will provide information on the selection of cost-effective s...     Read More

Abstract: This paper presents a novel Current Steering Digital to Analog Converter architecture to reduce area as well as power dissipation. The current cells of conventional binary weighted architecture require larger size of transistors for MSBs. In this paper, same sized current cell transistors for MSBs a...     Read More
