Abstract - A microstrip patch antenna is a metal patch placed on a substrate. Different feeding modes are used such as: coaxial probe feed, microstrip line feed, proximity-coupled feed, coplanar wave guide feed (CPW) and others. These feeding modes are divided in two kinds, direct or indirect. The patch can take different shapes; the most known forms are rectangular, square, circular, hexagonal... The microstrip patch antenna is low-profile, conformable to planar and non-planar surfaces, simple and cheap to manufacture using modern printed-circuit technology. In this paper, a microstrip patch antenna for 2.45GHz applications is designed based on the transmission line method. The design is optimized with the Method of the Moments (frequency domain method) because its one of the accurate methods for wire and planar antennas. The three direct feeding modes are studied, manufactured and measured. Simulations were performed with CADFEKO and measurements were performed with Vector Network Analyzer (VNA) Anritsu MS2026C. |

Abstract - In order to compete in todays highly competitive marketplace, Lean Manufacturing is typically accepted philosophy which helps industry by making them able to compete, face challenges and evolving people for next level of challenges. The purpose of this paper is to increase the awareness level of a local industry in Benghazi to the role that lean manufacturing plays in identifying the type of waste. Also, help to reduce or, if possible eliminate the waste altogether, in order to improve their productivity, efficiency, and profitability. As a result of this study to get benefit from lean as a total system, we need to create the right culture for it. |

Abstract - Recently, Governments seeking to develop the provision of services to citizens and companies associated with these its citizens. By development of technologies and means of communication, governments also tended to use e-government to improve and facilitate the provision of its services. Cloud computing has emerged recently as an influential and effective in providing and facilitating the provision of services via the Internet. where it provides how to submit everything to you as a service wherever you are at any time you need.The aim of this research is to analysis the impact of using of cloud computing in e-government and infrastructure required for the use of cloud computing in e-government in Yemen. It also Explains cloud computing models, security, and risks which could be faced by the e-government and ways how to develop and improve cloud computing. Type of this research is descriptive and analytical approach (Quantitative Method) was adopted as a scientific approach commensurate with the nature of this research to identify the best approaches of requiring cloud computing in e-government. |

Abstract - The rapid increase of Temporomandibular Joint Disorder (TMJD) cases has caught the attention of medical industry. However, only few of these cases has been diagnosed properly due to unawareness of the patients and of the high cost of diagnosis. Today, medical mobile applications is becoming prevalent to aid medical specialists and patients. This research study focused on the methods for self-diagnosing TMJ disorder using symptom questionnaire and mesurement of the maximum mouth opening. With incremental development as a software development tool, the mobile application was programmed using Android Studio. Measurement of the maximum mouth opening through image processing involves detecting face and face landmarks, mouth opened/closed detection, distance measurement, Euler Angle modification and measurement of the actual maximum opening with the aid of Google Vision API. A myofascial exercise recommended for relief of pain associated with TMJ disorder is also included in the mobile application. With an average percent difference of 1.21, there is no significant difference between the manual and the mobile measurement of the maximum mouth opening. Evaluated by TMJ practitioners, the mobile application is recommended for self-diagnosis and first-aid of TMJ disorder. |

Abstract - This paper presents the core concepts and different architectures of the parallel processing in computer systems. Parallel processing is most commonly used technology in todays computer systems to speed up the computation and data processing power. We present the detailed overview of the different parallel processing architectures and their working in detail. In this paper, we discussed about seven parallel processing architectures, such as, SIMD, MISD, MIMD, vector processing, SMP, NUMA and cluster systems which can be used in our computer systems to strengthen the computation and processing power. We also discuss the key factors of each architecture and situations when to use the given architectures. The one-unit discussion of all architectures provides the concise overview of them and their role in computer organization processing. |
