Most e-governments have traditionally used version 1.0 of the Web Content Accessibility Guidelines (WCAG) as a basis to ensure that their websites are accessible by people with disabilities. This was reflected in their design guidelines, accessibility evaluations, policy-making and legislations. Recently, WCAG 2.0 emerged as an ISO/IEC International accessibility standard that has been recommended for adoption by the W3C WAI. This paper seeks to examine if there is a need for e-governments to reassess their web accessibility conformance, in light of the latest WCAG 2.0 standard. A case study related to the 21 Dubai e-government websites is presented whereby accessibility is evaluated based on the WCAG 1.0 and WCAG 2.0 guidelines and using automated accessibility testing tools. We found that WCAG 2.0 conformance testing identified some notable accessibility issues that were not revealed by WCAG 1.0 conformance testing. Hence we recommend that e-governments should develop and update their web content and accessibility policies to conform to the latest WCAG 2.0 guidelines and success criteria. Additional implications for practice and academic research are also provided.

Recently, increasing data transmission rates and the demand of more bandwidth at the same time have been a challenge. The trend now is to support high data rates in wireless communications. Multicarrier systems have overcome many challenges of high bandwidth efficiency and at the same time provided also high spectral efficiency. Filter bank multicarrier systems (FBMC) provide some advantages more than the traditional orthogonal frequency division multiplexing (OFDM) with cyclic prefix (CP). FBMC systems provide a much better spectral shaping of the subcarriers than orthogonal frequency division multiplexing (OFDM). Therefore, the most obvious difference between the two techniques is in frequency selectivity. In this paper, we will present a least-meansquare (LMS) algorithm which is based on well-known cost functions, which is the mean-squared error (MSE) adapted for FBMC system with offset QAM modulation (OQAM). This leads to a per-subchannel adaptive equalizer solution with low complexity. The proposed simulations have used practical channel information based on the International Telecommunications Union (ITU) Standards. Moreover, we will discuss how the proposed algorithm will optimize and evaluate the convergence characteristic curves of LMS equalization algorithm per-subcarrier.

Nowadays, the evolution in transportation technologies makes the necessity for increasing road safety. In this context, we propose the implementation of a smart onboard GPS/GPRS system to be attached to vehicles for monitoring and controlling their speed. In case of traffic speed violation, a GPRS message containing information about the vehicle such as location and maximum speed is sent to a hosting server located in an authorized office so that the violated vehicle is ticketed. Moreover, this system can also track the vehicle’s current location on a Google Map, which is mostly beneficial when vehicles should follow a specific road and in case of robbery. Also geo-casting can have a major role in this model. Some sensors, such as shock/vibration sensor usually attached to the air-bags in vehicles, are attached to the system that in case of accident, it will send notifications to the nearest hospital, police station and civil defense. Our proposed model can be utilized for different implementations, both in public and private sectors. While similar existing systems in Palestine have focalized just on the tracking aspect of vehicles’ monitoring, it would be the first system supporting both ticketing and tracking.

One of the main keys of positioning and ranging technologies in wireless telecommunication networks is the values of distance and RSSI (Received Signal Strength Indication), side along with the cell perimeter have a significant relationship for the effect of the network quality in terms of quality in services and connectivity, and not less in the roaming stage. Many research results drove to influence these keys to the handover delay in the broadband network, so in many cases that MT handover between the boarders of location areas or zones has been affected by long time delay and packet data lost. Over recent years many signal propagation schemes have been presented to describe the relationship between cell size and Mobile terminal distance between the current and the targeted base station and RSSI. In this paper, the modify scheme of the location management area (LMA) -based multimedia broadcast services scheme has been presented , the effect of cell size and distance between BS and MT and the RSSI , which shown their influence of the handoff delay . The analytical algorithm results showed the reduction of the handover delay in smaller perimeter cell size compared to the large cells in location management area.

In a time when virtual organizations are fast becoming a phenomenon, this paper aims to explore how IT-based approaches—and in specific the object-oriented (organic) approach—can be used to structure and facilitate the management of such virtual organizations. As with traditional organizations, a virtual organization needs a structure that is fast, reliable, adaptable and deterministic. In addition, such organizations need a time and cost-efficient structure to allocate resources and maximize their utilization in a way that avoids deadlock and priority inversion. This paper sets out to present how the organic approach can meet the virtual organization’s needs; it will also illustrate how this approach can be applied to the technology sector of Egypt’s Ministry of Transport.

Software engineering ontology was first developed to provide efficient collaboration and coordination among distributed teams working on related software development projects across the sites. It helped to clarify the software engineering concepts and project information as well as enable knowledge sharing. However, a major challenge of the software engineering ontology users is that they need the competence to access and translate what they are looking for into the concepts and relations described in the ontology; otherwise, they may not be able to obtain required information. In this paper, we propose a conceptual framework of a multi-agent based recommender system to provide active support to access and utilize knowledge and project information in the software engineering ontology. Multi-agent system and semantic-based recommendation approach will be integrated to create collaborative working environment to access and manipulate data from the ontology and perform reasoning as well as generate expert recommendation facilities for dispersed software teams across the sites.

The concept of organizational commitment has been studied extensively during the past decades, and remains one of the most challenging and studied concepts in organizational research. In purchasing as well as in supply chain management, commitment plays a central role, because the personnel work directly with outside organizations, and consequently their performance can have a significant effect on the total effectiveness of the organization. This paper discusses organizational commitment and its importance in supply chain management and in the purchasing function. In addition, the principles of our newly developed Internet-based evaluation instrument are highlighted. This application has been preliminarily tested and the verification and validation processes are currently under evaluation.

An ongoing goal in higher education is to provide quality education programs and to produce high quality graduates. While much of the attention to quality matters is focussed on outputs, there is little that addresses the preliminary or input side of the educational program. The purpose of this paper is to demonstrate that it is feasible to construct a course profile based on standard inputs in the form of the behavioral objectives that are stated for the subjects comprising the course. The application of the course profile will be found in supplementing the understanding of quality frameworks in the assessment of degree programs, thereby becoming a useful tool for benchmarking courses and comparing across department and institution boundaries.

Regression tests are executed when some changes are made in the existing application in order to check the negative impact of the changes in the rest of the system or on the expected behavior of other parts of the software. There are two primary options for test suites used during regression testing, first generate test suites that fulfill a certain criterion, or user session based test suites. User-sessions and cookies are unique features of web applications that are useful in regression testing. The main challenge is the effectiveness of average percentage fault detection rate and time constraint in the existing techniques. Test case prioritization techniques improve the performance of regression testing, and arrange test cases in order to obtain maximum available fault that is going to be detected in a shorter time. Thus, in this research the priority is given to test cases that are performed based on some criteria related to log file which collected from the database of server side. In this technique some fault will be seeded in subject application then applying the prioritization criteria on test cases to obtain the effectiveness of average percentage fault detection rate.

Fingerprint classification is an important phase in increasing the speed of a fingerprint verification system and narrow down the search of fingerprint database. Fingerprint verification is still a challenging problem due to the difficulty of poor quality images and the need for faster response. The classification gets even harder when just one core has been detected in the input image. This paper has proposed a new classification approach which includes the images with one core. The algorithm extracts singular points (core and deltas) from the input image and performs classification based on the number, locations and surrounded area of the detected singular points. The classifier is rule-based, where the rules are generated independent of a given data set. Moreover, shortcomings of a related paper has been reported in detail. The experimental results and comparisons on FVC2002 database have shown the effectiveness and efficiency of the proposed method.

The Elliptic Jes window forms are original studies introduced by the author in Mathematics and Signal Processing in 2012. They are based on an Elliptical Trigonometry function “Ejes” in which it can produce a large number of different signals and shapes by varying only one parameter. In this paper, the developed study is the application of the Elliptical Trigonometry in signal processing in which some formulae are introduced using the function “Ejes”, these formulae has many advantages ahead the traditional window functions such as improving the convergence of the Fourier series at the discontinuity more rapidly compared to the traditional window functions, the proposed window functions are used to truncate the Fourier series with variable window shapes that keep the necessary information about the signal even after truncation. The proposed window functions are variable in form; they can take a huge number of different forms by varying only a few numbers of parameters. The proposed window functions can be used in both analog and digital design of filters. In fact, the General trigonometry and its sub-topics such as Elliptical Trigonometry can have also other applications in any scientific field that uses the trigonometry and it can improve all previous studies by replacing the traditional trigonometric functions such as cosine and sine by General trigonometric functions such as Gjes and Gmar or other functions.
