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...
In recent years, SQL injection attacks pose a common and serious security threat to web applications: the attackers are given rights to obtain unrestricted access to the database underlying the applications and to the confidential information these database contain, and it is becoming more popular and prevalent amongst hackers. According to recent data, between Q1 2012 and Q2 2012, there has been an estimated 69 percent increase of this attack type. [1][2] As we can imagine, a hacker gaining...
INTRODUCTIONOVERVIEW In order to achieve both compression and security, there are two possible approaches. One is to use general compression techniques followed by an encryption method using a stream or block cipher.Next approach is to incorporate security by modifying the compression method.The later approach offers additional design flexibility and hence computational simplifications.This may hence be a good approach to encrypt the large amounts of data.Two compression methods have been...
Abstract. Document Clustering plays a vital role in providing better results for document retrieval and document mining. Conventional techniques, such as vector space model have not been able to satisfy the Information Retrieval needs. They use word counting and frequency distribution to cluster documents. These techniques do not consider the semantic relationship between the words. In Phrase based model, word sequences are given importance, as the meaning of natural language strongly depends...
