Pmsm Sensorless Speed Control Drive, Youakim Kalaani, Rami J. Haddad, Adel El-Shahat Dec 2014

Pmsm Sensorless Speed Control Drive, Youakim Kalaani, Rami J. Haddad, Adel El-Shahat

Department of Electrical & Computer Engineering Faculty Research & Publications

Permanent magnet synchronous machines (PMSM) are very popular in many industrial applications such as in mechatronics, automotive, energy storage flywheels, centrifugal compressors, vacuum pumps, and robotics. This paper proposes Sensorless control for a PMSM speed drive which is based on a closed loop control system using a proportional and integral (PI) controller that is designed to operate in flux weakening regions under a constant torque angle. This Sensorless element was adopted for best estimating the PMSM rotor position based on its performance characteristics eliminating the need for speed sensors which are usually required in such control applications. To achieve this …


Google Forms: A Real-Time Formative Assessment Approach For Adaptive Learning, Rami J. Haddad, Youakim Kalaani Jun 2014

Google Forms: A Real-Time Formative Assessment Approach For Adaptive Learning, Rami J. Haddad, Youakim Kalaani

Department of Electrical & Computer Engineering Faculty Research & Publications

In this paper, we describe our approach on how to achieve an adaptive learner-centric environment by using an unconventional student feedback process that utilizes Google Forms to periodically collect information about the course instruction. Students were asked to provide their input regarding lectures' clarity and content; the use of visual aids; time management; problem solving, instruction delivery; and student engagement in the classroom. Data collected from these anonymous surveys provided real-time formative feedback that helped faculty to react just in time to address issues related to student learning process. In addition to providing continuous feedback, this process has also shown …


A Unified Approach To The Assessment Of Student Learning Outcomes In Electrical Engineering Programs, Youakim Kalaani, Rami J. Haddad Jun 2014

A Unified Approach To The Assessment Of Student Learning Outcomes In Electrical Engineering Programs, Youakim Kalaani, Rami J. Haddad

Department of Electrical & Computer Engineering Faculty Research & Publications

In this paper, a unified approach to the assessment of student and program learning outcomes to satisfy ABET and SACS accreditations criteria is proposed. This new approach takes into consideration the criteria of both accreditations to streamline the assessment process. As a result, a set of six skills categories were developed for SACS in which the eleven ABET student learning outcomes were embedded to satisfy both accreditation criteria. Furthermore, a standardized set of artifacts and rubrics were also developed to measure each skill category based on a given set of performance indicators. Data collected at the sophomore, junior and senior …


Adaptive Teaching: An Effective Approach For Learner-Centric Classrooms, Rami J. Haddad, Youakim Kalaani Jun 2014

Adaptive Teaching: An Effective Approach For Learner-Centric Classrooms, Rami J. Haddad, Youakim Kalaani

Department of Electrical & Computer Engineering Faculty Research & Publications

Adaptive Teaching: An Effective Approach for Learner-Centered Classrooms ABSTRACTWith the recent focus on student achievement, teachers are striving to improve the quality oftheir instruction methods to achieve a learner-centered environment in their classrooms. Thedifference in the students’ level of achievement in any specific course is mainly due to thedifference in the students’ aptitude for learning “Learning Style”. Unfortunately, the statictraditional teaching style “Chalk-&-Talk” which is still being used in engineering schools doesnot adapt to the changes in the cognitive profile of the student cohorts which reflects negativelyon the students’ achievement and performance, especially in engineering.In this paper, we discuss our …


Continuous Improvement In The Assessment Process Of Engineering Programs, Youakim Kalaani, Rami J. Haddad Mar 2014

Continuous Improvement In The Assessment Process Of Engineering Programs, Youakim Kalaani, Rami J. Haddad

Department of Electrical & Computer Engineering Faculty Research & Publications

In this paper, we present a multifaceted assessment process that was developed for our Electrical Engineering (EE) program at Georgia Southern University to meet the ABET criteria dealing with the student learning outcomes (SLOs). Both direct and indirect measures were used to collect and analyze data to assess the attainments of the student learning outcomes. To ensure data integrity, multiple faculty were involved in the development of a set of rubrics with benchmarks and performance indicators at both the program and curriculum levels. These tools provided action plans for this continuous improvement process to be implemented during the academic year. …


Gaming Against Plagiarism (Gap): A Game-Based Approach To Illustrate Research Misconduct To Undergraduate Engineering Students, Rami J. Haddad, Youakim Kalaani Mar 2014

Gaming Against Plagiarism (Gap): A Game-Based Approach To Illustrate Research Misconduct To Undergraduate Engineering Students, Rami J. Haddad, Youakim Kalaani

Department of Electrical & Computer Engineering Faculty Research & Publications

In this paper, we discuss our experience using a set of games called "Gaming Against Plagiarism" to increase awareness in different types of research misconduct, and highlight the ramification of committing such misconducts among undergraduate engineering students. Gaming Against Plagiarism consists of three mini-games that address research misconduct. The types of research misconduct addressed are stealing, misquoting, patchwriting, insufficient paraphrasing, self-plagiarism, data falsification, and data fabrication. In these games, students are virtually put into situations involving research misconduct. The students either have to identify the type of misconduct or make an ethical decision by avoiding research misconduct. We assessed the …
