Design Electronic Circuit Temperature Control Using Atmaga8 Controller

This work presents the details of the construction of the temperature control system in the center. We used the Atmega8 microcontroller which has high performance speed and suitable memory.

Design of State Feedback Controller to Control of the inverted pendulum

In this research a proportional integral differential classic (PID controller) and state feedback controller was designed to control the in the inverted pendulum and a comparison between all the cases and choose the most suitable controller using MATLAB / SIMULINK program

Developingan adaptive controller based on cerebellar model

In this study we developed an adaptive model inspired by internal models in the cerebellum and this approach called Feedback Error Learning (FEL). FEL is the origin of Learning Feed-Forward Control (LFFC). It depends on Feedback Controller and Feed-Forward Controller which is a Neural Network, and this Neural Network uses feedback controller output as training signal. We developed this approach to control a robot arm, and to balance inverted pendulum and to control bus suspension system. We developed this approach by adding a second Neural Network, and this new Neural Network uses FEL controller output as training signal. We simulate these systems by using Matlab and Simulink, and we find that this development improves control performance.

Evaluating the Effectiveness of Employees’ Performance Appraisal in Public Hospitals: A field Study in the Public Hospitals of the Syrian Coast

This research aims to examine the concept of Employees’ Performance Evaluation, as it is an important strategy that helps managers take an objective decision about the employee’s performance level. Also, it informs the extent of improvement that has occurred as related to the employees’ completion of tasks and their ability to bear highlevel responsibilities and extra duties. Such appraisal will have a positive effect on achieving the objectives of the hospital and increasing its performance efficiency. This research studied the most important factors that affect performance efficiency in the public hospitals of the Syrian Coast. To conduct this research, questionnaires and descriptive, analytical, and statistical techniques were utilized to collect statistics. They were later analyzed by the statistical program SPSS. The findings of this research showed weak experience in evaluation methods and techniques. It was also surmised that no feedback was given to the employees. Such feedback should be required as it orients the employees with the level of their performance and makes the opportunity to improve possible. The recommendations of this research suggest that evaluators should undergo sufficient training in order to be oriented with evaluation concepts and techniques. Also, a suitable feedback about performance should be made available to the employees.
