Today's broadband Internet connections are restricted to wireline infrastructure using DSL, T1 or cable-modem based connection. However, these wireline infrastructures are considerably more expensive and time consuming to deploy than a wireless one. Moreover, in rural areas and developing countries, providers are unwilling to install the necessary equipment (optical fiber or copper-wire or other infrastructures) for broadband services expecting low profit. Broadband Wireless Access (BWA) has...
Artificial Intelligence is the subfield of Computer Science that tries to make machines more intelligent, by experimenting with new forms of logic and reasoning. The human settlement of Space requires good tools like AI mass spectrometer, and the best tools are intelligent machines. Just as the computers are present everywhere in space programs around the world for processing of information, advanced software will be applied in every aspect of the settlement of Space for which increased...
Netware is a cost effective platform also reliable for delivering security and network access to recourses which makes it fitting for business starters. The NetWare 6.5 is flexible with some choices that may help the administrator delivering an excellent production. Thus NetWare saves money, administration time and provide more service. Netware 6.5 has improvement of clustering support up to 32 servers also keeps the network recourses available even if there is maintenance on that server. The...
An IEEE 802.11 networks has been proved to provide a certain level of quality of services by the means of service differentiation, but due to the changes and amendments in the IEEE 802.11 e. No method or accurate mechanism has been proven to provide the standard and accurate levels of available amount of resources in the network, even some irresponsive fields in the network may effect the estimations. Such an estimation level of available amount of resources in the network may be a good...
Multi-touch allows the user to have a full on interaction with a visual display unit at the touch of their fingertips. Commands are identified as gestures which are created by the movements of the fingers across the screen. These commands are then sent to a device to carry out the instructions implemented. This sort of technology is widely used as a tool for interacting with smart phone devices or computer screens [1], and would be considered as a replacement for contemporary devices such as a...
ABC Complete Kitchens will need to develop an information systems framework that can support the strategic objectives of management. "An information system (IS) can be any organized combination of people, hardware, software, communications networks, data resources and policies and procedures that a store, retrieves, transform and disseminates information in an organization." {{57 O'Brien-Marakas 2008, p. 2, para. 5}} The IS framework is organized in the following areas: management...
Human errors maybe categorized under six groups with respect to engineering: design errors, assembly errors, installation errors, inspection errors, operating errors and maintenance errors. Maintenance error is the result of the wrong preventive or repair actions carried out by the craft or assigned personnel. Base on the frequency of maintenance being performed the probability of human error increases. To reduce some human errors maintainability is important in the design phase of a component...
Eye based human computer interaction techniques have thus far been limited to closed environments. However advancement in technology and advent of mobile computing promises to bring eye based interaction techniques to wearable and handled mobile devices. This paper investigates recent methods to track eye movements in the mobile environment. Methods were evaluated by comparing the techniques they rely on, type of work, use of theoretical proofs and simulations. Mobile computing is the modern...
A secure web server provides a protected fo undation for hosting your web application and Web server configuration plays a critical role in your Web application's security. Badly configured virtual directories, a common mistake, can lead to unauthorized access. A forgotten share can provide a convenient back door, while an overlooked port can be an attacker's front door. Neglected user accounts can permit an attacker to slip by your defenses unnoticed. What makes a Web server secure? Part of...
Next generation wideband and ultra-wideband radar antenna arrays need efficient true-time delay networks for array control. Optical beam-forming networks have been considered as a promising solution in such arrays. Performance analysis of optical beam-formers is, thus, quiet necessary. In this paper, the signal to noise ratio and the dynamic range of simple optical beam-forming structures are investigated with a custom microwave CAD tool. Two structures with optical and RF power combining...
