    Fast Technique to Recognize Closed Characters in Arabic Handwriting
    (October university for modern sciences and Arts MSA, 2023) Gad, Ramadan; Kandeel, Shaimaa; Al-Adawy, Mohamed; El-Fishawy, Nawal; A. A. Mohamed, Mokhtar
    Considering the distinctive features and characteristics of Arabic scripts, recognizing handwritten Arabic characters is still widely open as a major experimental task, which is not easy to overcome. This study attempts to develop a fast and effective technique for recognizing this difficult type of written script by using an iterative algorithm to extract closed Arabic characters. Some Arabic characters have circles that may be blurred, incomplete, unformed, or distorted. In addition to ligatures with different shapes, the technique is based on the development of a proper Circular Hough Transform. This study used IFN/ENIT, which is a standard database for extracting closed Arabic characters as designed in classes. The first class is closed blurred circles (ق, م , ع ,و ). The second class is unformed circles ( ق, ع , ة ). The third one is incomplete circles (ط , ظ, ص, ض ه,ة, ). Finally, the fourth class is distorted circles ( ط, ظ ). This methodology achieved an outstanding accuracy of approximately 96.67%, a very interesting work for the total four classes related to the 11 closed Arabic characters (out of the 28 characters of the Arabic alphabet)..

    USANet: an open platform for USB-based Sensors/Actuators Network
    (October university for modern sciences and Arts MSA, 2023) Mohamed, Mokhtar; El-Shafeiy, Engy; Gad, Ramadan; ElMahalawy, Ahmed
    The paper presents and proposes USB-based Sensors/Actuators Network (USANet) system. Proposed USANet system is maturely designed according to IEEE 1451 concepts and component-based approach. It consists of five STIMs. These STIMs are Measurement Module of Speed (MMS), Controller Module for Motor (CMM), three Measurement Modules of Distance (MMDs). They are connected to a laptop NCAP host via five USB 2.0 interface cards. Each USB 2.0 interface card is dedicated for only one STIM to exchange messages of sensory data or control commands with NCAP host. USB 2.0 interface card represents TII of such USANet. NCAP host run a program called SCCD. SCCD is the abbreviation of Sensory data Collector/Command Distributor. It is an open source model that is developed by C# programming language under the dot-Net 4.0 framework to provide portability. SCCD is employed to collect sensory data from MMS, and three MMDs. In addition, SCCD sends control commands to CMM. All hardware and software modules of USANet are designed and developed completely in our labs. Two performance metrics are used to validate and verify the feasibility of such USB-based Networked system. They are Feedback Receiving Time (FRT) and Sensory Data Message Time (SDMT). These timebased metrics are chosen for evaluation because the provision of timely information is crucial in many applications
