In this research, a compact of four elements of dual ports coplanar wave guide (CPW) ending with T-shape stub are installed each one on a corner of 85×134 mm2 printed circuit board (PCB). Each element is connected through the SMA connector 'panel mount jack receptacle-2-hole flange-tap terminal'. A twin of opened circular parasitic rings are installed in front of each T-stub. A large number of try and error are applied to select the optimum geometry dimensions of the proposed paradigm. The result of paradigm show that each element operated with a resonance frequency 6.35 GHz, 7.1 GHz is the operating frequency overall system. Also, by utilizing the twin of opened circular parasitic ring, a good isolation is achieved with -48 dB. The obtained band frequency 1.74 (6.64-8.38) GHz are covered an important part of UWB which may be used at a sub band of 5G. In addition, the size of the prototype is suitable for future smartphone applications

Potential university students have to prove readiness to acquire modeling competence if they get enrolled in an Information Systems (IS) program. University admission is generally based on scores acquired in pre-university education and based on conventional assessment which puts the students in stress and panic where they cannot perform to their full potential. In this paper, games based assessment which can be considered a type of stealth assessment is proposed to assess the modeling readiness. A player in a game performs in a natural setting that helps proper evaluation. The paper presents conventional readiness assessment scenarios, maps them to a number of games scenarios which are then developed into a game. The game addresses readiness levels related to modeling as well as other competencies. Aspects and choices related to game design are presented. The game is intended to be part of a bigger platform for assessment and assignment of students to academic programs. The game has been developed in unity and the first version tested by some students who would potentially enroll in Alexandria University, Egypt.

IOP Conference Series: Materials Science and Engineering 2020年第1期745卷

作者： M M Abdulwahid M S Al-Hakeem M F Mosleh R A Abd-alhmeed Department of Computer Engineering Techniques Electrical Engineering Technical College Baghdad Iraq Department of Computer Science Dijlah University College Baghdad Iraq School of Engineering and Informatics University of Bradford Bradford UK

In indoor communication, when handling the design issue for the wireless network, it is very important to select the appropriate wireless Access Point (AP) devices and specify the optimum locations for these devices deployment. In addition, reducing the total number of disseminated devices. In this paper, it has been investigating the network performance on the presidency building of middle technical university and based on AP deployment in the targeted building. Such investigation has been achieved using Wireless InSite software, based on the calculation of the parameters of path loss, and received power. Results obtained show significant variation in network performance and coverage at a different part of the building. As a result, a significant contribution has been proposed in enhancing the network performance, reducing the number of utilized AP devices from 13 to 8 devices. Furthermore, reducing both the total implementation costs and the interference effects inside the building.

In recent years, finger vein recognition has taken a noticeable attention. It is greatly employed for many applications due to its multiple advantages; for example: small and easy to use scanning device, its accuracy and convenience compared to other hand-based biometric models. For years researcher presented promising finger vein recognition approaches, nevertheless, there are problems and challenges in finger vein localization, feature extraction and identification. In this paper, we study twenty two finger vein recognition systems and view the methods and the techniques for which these systems built to serve. the variety of methodologies of these systems are reflects the differences in accuracy and performance for which it is vital to know which presented methods and proposed ways to reduce the outcome; so that more suitable techniques to be produced for building more robust systems.

Most of the medical diagnostic requires studies of medical images for to give an accurate treatment. Therefore is important the improvement of the medical images in terms of noise, quality, and morphological definition. The medical images series contains approximately 20% of noise caused by the equipment itself, especially in the x-ray modality. Therefore, the principal aim of this project is to develop an algorithm that helps suppress the noise as a preprocessing stage before medical analysis. The algorithm for noise reduction proposed uses classic and optimized mean filter, Gaussian filter, and median filter. This project also uses OpenMP parallel programming to optimize processing time and computational resources. The parallel implementation results of algorithms with sequential and classic implementation show great performance in the quality of the time processing, noise localization, and noise reduction. This improvement helps medical professionals get better details about the different pathologies for effective diagnostics and treatment. © 2019 International Association of Engineers.
