Bus topology: A bus network topology is a network architecture in which a set of computers are connected via communications line, which is called a bus. Bus networks are the simplest way to connect multiple computers, but it may have problems when two computers want to transmit at the same time on the same bus. The bus topology connects each computer on the network into something called the segment trunk. A bus is usually referred to a cable that connects end to end and this is used to transmit...
It is being demanded from WLANs to provide solutions for a wider range of needs. Inexpensive, reliable wireless networks allow industrial users to enhance data collection, human-machine interfaces (HMI) and web-based system monitoring, programming and management. The time and expense of running cables challenge the implementation of new projects. Wiring and cabling have occupied the major part of economical burden of the industrial communications. They are used as a communication medium for...
As the technology advances the human society expects comfort and time saving. S-Mail - Interactive speech mail service developed for person who requires comfort and it is essential for a person with disability. S-Mail system can read aloud mails and can send or compose mails through speech avoiding eye strain. It can be employed as an aid for the people who suffer with visual impairment (i.e.) the user can receive, compose and send mails and can access mail page through speech such as...
Dawei Gao and Xiaorui Sun tackles fairly the issue of harmonics elimination, unbalanced problems and power factor compensation. This work presents a three phase shunt active power filter with control method based on the traditional neural network algorithm, extracting the fundamental sinusoid from distorted load current waveform without harmfully phase shift due to adapting electronic bandpass filters. The control circuit is used in generating the reference current of the compensation current...
The following report presents a proposal to implement a wireless campus network that can enable the students, university staff and faculty and guests to use the existing networking features available at the university such as the university network, internet, university mail etc with better and flexibility. This proposal aims to address the key points involved in implementing a campus wireless network which includes the infrastructure requirements for implementing the network, security...
Web applications contain so many information and communication materials that web application testing is becoming an enigma for many testers. The web application contains much more complex environment than a stand-alone desktop or typical client-server environment. If the web applications stop working, the problem might be positioned in the applications code or in the application's compatibility with other system components, or in communications problems between the components that are totally...
Apart from the science fiction, science knows various numbers of ways to levitate things. For example, a helicopter can be seen as a very remarkable levitation device that uses air flow to keep floating. The scientists also found many ways to levitate things without making noise or the need for gas or air, using electromagnetic fields. Levitating trains is the example of electromagnetic levitation. However, in all these plans, a source of energy (an engine or a battery at least) is still...
According to question 1, group of business employees wants to build up a small networking office. A good computer network should builds up with minimal cost of physical media and installation, but the maximum performance, which helps lower the business budget and optimizes business productivity. It is also must have the scalability and flexibility to make changes, to upgrades, to increase stations, to increase coverage, and etc, when in time of a huge increases of demand. Moreover, the computer...
A computer is a programmable machine that can receive input, store and handle data and provides output for the users. The first computer was developed in between 1940 to 1945. It is built by IBM and it has the size of two factories. It consumes as much power as few hundreds of modern personal computer (PC). However, modern days computer are more capable than the old computers and it occupy very small space. Computers can be differentiated into various types. For example, the mainframe, super...
Ajax and Adobes Flash Flex are both used to create dynamic and interactive web applications. Both permits for interface animation and are platform independent meaning contents will render the same across different platforms. There are many similarities between the two. However, there are considerable differences as well. For example, Flash is an animation format software that allows for the quick download of animation files in a resizable format that lets files be downloaded over a regular...
