Abstract: Program logic controllers are widely used in industry either to control the manufacturing process or the processing plant. Thus, any faulty behavior in the program logic controller will have a crucial effect on both of the industry or/and labors. Therefore, it is important to be able to detect and diagnose any fault in the program logic controller. This paper introduces a new debugging technique; it combines both of the program slicing and the algorithmic debugging techniques. This is attained by making use of the instruction list programming to perform the debugging techniques and then it is converted into a control flow graph before applying the new combination between the slicing and algorithmic debugging. Through the use of these techniques, the debugger can utilize the feedback from the user to detcet the fault and find the source of this fault.

Abstract: This paper is concerned with the modeling, design, and implementation of controllers for a heat sink system using a Single Board Computer. Temperature data is collected from an electrical circuit plant and used to develop a block model using MATLAB Simspace. Then, the Simscape model is used to design a Proportional-Integral-Derivative controller in a simulation environment. Two techniques, Control Prototyping and Hardware-In-the-Loop, are used to validate the controller results. Finally, the Proportional-Integral-Derivative controller is embedded in BeagleBone Black and connected to electrical circuit plant. Experimental results show that the BeagleBone Black can implement Proportional-Integral-Derivative controllers in real-time environment with accurate results.

Abstract: Tracking applications such as robotics, actuation, manipulation and radar antenna system employing four-quadrant thyristorized D.C. drive require precise and optimal speed control. In this paper, the analysis and design of an adaptive current controller of a separately excited d.c. motor with a thyristor converter using z-transform technique is presented. With an adaptive current controller, the current loop will have the same dynamic characteristics whatever may be its operational state. A hardware realization of the controller is also discussed. A digital simulation study is made of the performance of the closed loop speed control system using an approximate continuous time representation for describing its dynamics. The designed controller responses were simulated with the help of MATLAB to show the validity of the proposed method.

Research Title: Analysis and Design of an Adaptive Current Controller with DC Drives for Tracking Applications

Author: Mohammed Bani Younis, Published Year: 2019

Faculty: Engineering and Technology

Abstract: Tracking applications such as robotics, actuation, manipulation and radar antenna system employing four-quadrant thyristorized DC drive require precise and optimal speed control. A track is a time history of position and/or velocity that the end effector of a manipulator should follow at all time. In this paper, the analysis and design of an adaptive current controller for a permanent magnet d.c. motor driven by a four-quadrant thyristor converter is presented. The proposed adaptive current controller will enable the current loop of the closed loop speed control system of the DC motor to have the same dynamic characteristics whatever may be its operational state regarding continuous or discontinuous current modes. Current loop analysis is presented using z-transform technique. Criteria for the selection of the parameter and hardware realisation of the adaptive current controller are also discussed. A digital simulation study is made of the performance of the closed loop speed control system using an approximate continuous time representation for describing its dynamics. The hardware design of the controller is simple, reliable and easy to implement.

Abstract: This study came to inspect the impact of the development of both financial market and banking system on the economic growth of Jordan based on the annual data covering the period 1993–2017. Through the use of many methodologies: Johansen cointegration test, (VECM), and Granger causality test, where real GDP was used as an indicator of economic growth, the real market value of stocks (Market Capitalization) (LCAP) and Share Turnover (LTURN) are indicators for the financial market, Money supply in the broad concept (LM2), and Local domestic credit (LCR) are indicators for the banking sector.The results of this study reported that the study variables are stationary, and in the level of order 2, they are integrated, and a long-run relationship between the study variables existed according to the Johansen co-integration test. VECM model result and the target model result confirm a short-run causality running from the all variables toward GDP. Granger causality test underline a single directional causality running from variables of our study to GDP and denote the short-run impact between LCAP, LTURN, LM2, LCR, and LGDP. The analysis of the variance decomposition shows that the development of the banking system affects economic growth almost equally with the impact of the development of the financial market. The results go to the same line of supply-leading hypothesis.

Abstract: The aim of this study is to analyze the challenges facing small business who own a computer shop. 142 owners were selected . The study found that 45.1% of the sample are from Amman city, 32.4% of the small business age less than 7 years, 59.2% are male, 27.5% Age of Small Business owner are 30 years to less than 40 years .Descriptive statistics used to describe the characteristics of the sample depending on frequencies, percentages, means, and standard deviation, “t-test” and “ Scheffe posttest” for prior comparisons, ANOVA used to measure the effects of the independent variables on the dependent variable. The study found that the owners who are 45 years and more do not feel strongly that the challenges facing small businesses entrepreneurs are having enough cash to cover the bills and transform problems and frustrations into opportunities and hiring employees that can truly help business grow and getting customers or clients and identified measurable goals that support business vision and lack of training .The owner whose location of his small businesses in Irbid feel more than the one in Amman that flat out by big box retailers that they aren't brand builders is one of the challenges facing small businesses entrepreneurs and feel more than the one in Zarka that making customers happy is one of the challenges facing small businesses entrepreneurs. The owner who has a business aged 10 years to less than 15 years feel strongly that don't have big budgets to market and high unemployment rate are some of the challenges facing small business owners. The male feel more than the female that some of the challenges facing small businesses entrepreneurs are don't know how to start a business and don't know how to building a brand and having a client willing to pay on time for a product or service and transform problems and frustrations into opportunities and not knowing the impact of current legislation and getting customers or clients and Marketing business on the Internet and not paying the rent and unwillingness to accept being a small business

Abstract: ABSTRACT The main aim of this study is to answer one question: “What is the impact of non-verbal communication on the success in the learning process from the perspective of undergraduate students attending the Faculty of Business at Philadelphia University-Jordan?” The present study surveyed two-hundred-and-sixty students. Two-hundred-and-fifty questionnaires returned, ten questionnaires had to be discounted. The instrument was a questionnaire developed by the researcher, with modifications recommended by referees. Questions were measured on the 5-point Likert scale. Findings reveal that tone is one key of non-verbal communication since it can alter the entire meaning of a sentence. Accounting students most keenly report that silence is a powerful tool in non-verbal communication. It indicates that students are listening carefully and attentively. In addition, visual communication was deemed to have a major impact on non-verbal communication Second level students consider that appearance accounts for a huge proportion of non-verbal communication. Furthermore, they appreciated brief pauses by teaching staff, since these assist concentration and interaction between students. Students aged nineteen to twenty-one had stronger opinions than those aged under nineteen. The human face is a powerful tool in non-verbal communication, as is silence.
