Overview of Wireless Data Communications

Abstract:
Overview of Wireless Data Communications(networking) Selecting the appropriate wireless data communication solution for connecting low-bandwidth electronic devices requires several considerations. These considerations may include range related issues, power requirements, 900 MHz versus 2.4 GHz transmission bands, interference immunity and time-to-market issues

Advantages of Cellular Networks
More capacity due to spectral reuse
Lower transmission pow ....etc

Risk in financial services: An Overview

Abstract :

Today financial services companies operate in increasingly complex, competitive and global markets. The ability to manage risks across geographies, products, asset classes, customer segments and functional departments is of paramount importance and inability to manage the risk can cause the irreparable damage and financial risks are increasing day by day especially in insurance, commercial banking and investment banking. The objective of this pa ....etc

Abstract.
Precise positioning in indoor environments faces different challenges than the outdoor ones. While indoor environments are limited in size to rooms and buildings, outdoor positioning capabilities require regional or even global coverage. Secondly, the difficulty of receipting satellite signals indoors has triggered the development of high sensitive and AGNSS receivers “ with many issues remaining unsolved. Thirdly, the accuracy requirements are dissimilar between indoor and outdoor environments “ typic ....etc

AN OVERVIEW OF VIRTUAL REALITY
ABSTRACT :-
In our world today we are surrounded by a wonderful array of technologies. We have assimilated many of these technologies into our everyday lives. Increasingly, these different technologies are becoming integrated to provide new capabilities and services. And most frequently a computer is the heart of this integration. This is the case with Virtual Reality - a so-called technology which actually is a very sophisticated integration of a number of technologies.
Virtual Reality i ....etc

Reality is a computer-based technology which incorporates specialized input and output devices to aVirtualllow the user to interact with and experience an artificial environment as if it were the real world. A VR system permits the user to explore a three-dimensional virtual - or artificial - environment and to interact with lifelike and/or fantasy elements created by the designer. In the virtual world, the user can do things as routine as throwing a ball or as fantastic as flying through space. And these things can be made to occur by somethi ....etc

Embedded systems are increasingly becoming integral parts of almost all technology-oriented applications. Embedded systems are the unsung heroes of much of the technology we use today- video games, washing machines etc. The appliances using embedded systems are pre programmed to perform a dedicated or narrow range of functions as part of a large system, usually with minimal end user interaction and optimum performance. Embedded systems are used in navigation tools like global positioning systems (GPS), automated teller machines(ATMâ„¢s), ne ....etc

Connected Sensor Cover: Self-Organization of Sensor Networks for Efficient Query Execution (Java)
IEEE/ACM Transactions on Networking, Vol. 14, No. 1

Abstract:
Spatial query execution is an essential functionality of a sensor network, where a query gathers sensor data within a specific geographic region. Redundancy within a sensor network can be exploited to reduce the communication cost incurred in execution of such queries. Any reduction in communication cost would result in an efficient use of the battery energy, which is ....etc
