Abstract: This study seeks to extend Abor’s (2005), and Gill, et al., (2011) findings regarding the effect of capital structure on profitability by examining the effect of capital structure on profitability of the industrial companies listed on Amman Stock Exchange during a six-year period (2004-2009). The problem statement to be analyzed in this study is: Does capital structure affect the Industrial Jordanian companies? The study sample consists of 39 companies. Applying correlations and multiple regression analysis, the results reveal significantly negative relation between debt and profitability. This suggests that profitable firms depend more on equity as their main financing option. Yet recommendations based on findings are offered to improve certain factors like the firm must consider using an optimal capital structure and future research should investigate generalizations of the findings beyond the manufacturing sectors.

Abstract: Quality criteria and performance measurement are becoming essential tools for assessing and developing academic programs. In this paper, accreditation and quality criteria from six different agencies (ABET, QAA, ENQA, ASIIN, HEAC, and ISO) are gathered, compared, and tailored towards mechatronics engineering programs. Seven Criteria are identified: strategy planning, resources and student support, academic programs, student learning outcomes, research, local and international collaboration, and quality assurance. Then, 12 Key Performance Indicators (KPI) and seven Student Learning Outcomes (SLO) are selected. Quality assurance methodology proposed in this study can be used as the basis to measure the performance of mechatronics programs.

Research Title: Harmonics generation Due to Multi-Cycle Auto Reclosing on HV Transmission Lines

Author: Mohammed Bani Younis, Published Year: 2019

Faculty: Engineering and Technology

Abstract: The technology of auto-reclose has been widely used on overhead HV transmission lines in most of power systems. As most of the faults on a transmission line are transient in nature, the auto-reclose can greatly improve the reliability and stability of the power system. The purpose is to make the fault line re-run after the temporary fault elimination. In this work the generation and nature of harmonics during auto reclosing process is investigated using adopted Fourier series instead of Fourier transform. It is found that subharmonics as well as higher order harmonics of the line frequency are generated depending on the type and durations of the reclosing. Also the amplitude and phase-angle relationships of these harmonic components are calculated for multi-pole multi-cycle auto reclosing. The results were verified using fast Fourier transform. It is found that the adopted Fourier series method gives more accurate and clearer results for the nature of harmonics than those based on simulation techniques such as FFT and discrete Wavelet Transform (DWT).

Research Title: Combining Program Slicing and Algorithmic Debugging to Diagnose a PLC program

Author: Mohammed Bani Younis, Published Year: 2019

Faculty: Engineering and Technology

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.

Research Title: Temperature control of a heat sink based on Hardware in the Loop

Author: Mohammed Bani Younis, Published Year: 2018

Faculty: Engineering and Technology

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.
