Apple introduced their first tablet computer back in the early 1993 called the Newton MessagePad 100. Apple was then lead to a finer establishment within the ARM6 processor core together with Acorn Computers. The Newton MessagePad was a very premature personal data assistant (PDA) and was then improved immensely until it's withdrawal from production in the year 1993. They then started on manufacturing the Pen Lite, a prototype Power Book Duo - based tablet but concluded not selling the product...

The operational amplifier is undoubtedly one of the most useful devices in analog electronic circuitry. Op-amps are built with vastly different levels of complexity to be used to realize functions ranging from a simple dc bias generation to high speed amplifications or filtering. With only a handful of external components, it can perform a wide variety of analog signal processing tasks . Op-amps are among the most widely used electronic devices today, being used in a vast array of consumer,...

Project management in the business field is defined as managing and directing time, material, personnel, and costs to complete a particular project. One important phase in the project planning is Project Resource Scheduling. This process identifies resources amount and type according to the activity that scheduled. Planning the efficient use of resources is a complex task. The purpose is to create a smoother distribution of resource usage i.e. to minimize the fluctuation of the resource usage....

ABSTRACT Internet became a vital part in day to day life for wide-ranging population for many purposes like business transaction, instructive purpose etc. Since many organizations rely on online business transactions there is a need for their database to get secured from intruders. Every organization uses web application for accessing their data from the database, these applications uses user inputs to create a query for storing, retrieving data from the database. Although all the organizations...

Genetic Zone Routing Protocol (GZRP) is a new hybrid multipath routing protocol for MANETs which is an extension of ZRP by using Genetic Algorithm (GA). GZRP uses GA on IERP and BRP parts of ZRP to provide a limited set of alternative routes to the destination in order to load balance the network and robustness during node/link failure during the route discovery process. GZRP is studied for its performance compared to AOMDV, another multipath routing protocol extended from AODV, a source...

Introduction : Mac OS X is an operating system developed, marketed, and sold by Apple Inc., and since 2002 has been included with all new Macintosh computer systems. It is the successor to Mac OS 9, the final release of the "classic" Mac OS, which had been Apple's primary operating system since 1984.Features :Automatic location detection:When you travel, it's easy to get mixed up as to when your appointments are, since your computer is still in your "home" time zone, and you...

This paper describes the research and approach to the analysis of a medical knowledge management system that involves data acquisition and its representational formalisms based on processed information and causal knowledge mechanisms. In doing this, a use-case scenario is described with the central idea of integrating medical knowledge with available resources based on the Internet. This will satisfy the need of making medical knowledge and advice available to users based on services provided...

INTRODUCTION Web services are programmable units that provide specific functionalities and are accessible to a large number of consumers using Internet protocols. The existing server to server web services are not applicable for mobile devices as they suffer from interoperability. The promise of providing interoperability in a heterogeneous world, as well as the possibility of offloading operations that require high processing power, make the mobile phones an ideal target device for accessing...

Wireless Ad Hoc Network (MANET) is a network of wireless mobile nodes that communicate with each other without any network infrastructure. These nodes dynamically self- organize in temporary and arbitrary network topologies. As the nodes are in continuous motion, topology of the network changes constantly. In Ad Hoc network node can move into and out of radio range of other nodes. These nodes can communicate directly with other nodes in range or they use intermediate nodes to communicate with...

VPNs otherwise known as virtual private networks allow computers or a network of computers to connect to each other securely. VPNs use the internet to create a virtual "tunnel". Through this tunnel information is transferred from the source to its destination. Before VPNs, computers would have to connect to each other through physical wires that needed to be run from one location to the next. This was typically done by leasing lines through the telephone company. If you wanted your...
