...Show More Authors

The research aims to achieve a set of the most important objectives of the review of the role of creative administrative leadership in achieving aspects of economic reform in various government institutions and indicate the role of supervisory awareness of administrative leadership in the revitalization of the role of the internal control system to achieve the best use of available resources. This paper deals with three problems is the loss of financial resources of the state as a result of the growing phenomenon of administrative and financial corruption in the majority of government institutions, and the weakness of the role of the internal control system in the province on the resources available and to achieve the best use of these resources in accordance with the specified in the state budget law targets as well as weak oversight awareness of the majority administrative leadership, adversely affecting the achievement of the effectiveness of internal control system in particular, and the objectives of government institutions in general. Find kicks off in search solution to the problems of proving the following two hypotheses:1.The creative approach to the adoption of administrative leaders in government institutions contribute to support the effectiveness of the internal control system in the fight against manifestations of the administrative and financial corruption and achieve the desired administrative reform in all areas of economic life.2.The acquisition of administrative leadership awareness oversight contributes to the effectiveness of the internal control system in achieving the best use of available resources in various government institutions.The researcher reached a set of conclusions including:1.lack of technical reference clearly defined legal and regulatory framework can be referenced in the issues facing the audit and internal control departments in government institutions.2.weakness of senior management to recognize the role of internal control in the maintenance of public money and its role in supporting the administration's efforts to achieve the goals of the institution and reducing accountability.3.weak senior management in response to the need for oversight and internal audit departments to appoint directors of the sections of Control and Internal Audit hold advanced degrees specializing in accounting, auditing and in the appointment of sufficient number of auditors who have specialized degree in accounting.4.twice the regulatory qualification of internal auditors to meet the basic requirements of the regulatory function.The researcher presented a set of recommendations including:1.To recommend to the Council of Ministers to prepare a government program for the reform of the internal control system in isolation or within a comprehensive government program of administrative reform various aspects of the political, economic, social and cultural life.2.the appointment of auditors in control and internal audit departments who hold a bachelor's degree in accounting at least in all government institutions and that the auditors at the headquarters of the ministries who hold graduate degree in accounting.3.recommendation to the Ministry of Higher Education and Scientific Research, specializing in the creation of Control and Internal Audit holds graduate study obtained from the responsibility of oversight and internal audit departments management.4.Create a technical reference for internal control is based in the Ministry of Finance while maintaining the administrative reference to link to the top of the hierarchy and what contributes to the effectiveness of the system.

Optimal second order integral sliding mode control for a flexible joint robot manipulator
...Show More Authors

The flexible joint robot manipulators provide various benefits, but also present many control challenges such as nonlinearities, strong coupling, vibration, etc. This paper proposes optimal second order integral sliding mode control (OSOISMC) for a single link flexible joint manipulator to achieve robust and smooth performance. Firstly, the integral sliding mode control is designed, which consists of a linear quadratic regulator (LQR) as a nominal control, and switching control. This control guarantees the system robustness for the entire process. Then, a nonsingularterminal sliding surface is added to give a second order integral sliding mode control (SOISMC), which reduces chartering effect and gives the finite time convergence as well. S

Hierarchical sliding mode control applied to a single-link flexible joint robot manipulator
...Show More Authors

Trajectory tracking and vibration suppression are essential objectives in a flexible joint manipulator control. The flexible joint manipulator is an under-actuated system, in which the number of control actions is less than the degree of freedom to be controlled. It is very challenging to control the underactuated nonlinear system with two degree of freedom. This paper presents a hierarchical sliding mode control (HSMC) for a rotary flexible joint manipulator (RFJM). Firstly, the rotary flexible joint manipulator is modeled by two subsystems. Secondly, the sliding surfaces for both subsystems are constructed. Finally, the control action is designed based on the Lyapunov function. Computer simulation results demonstrate the effectiveness of

Littoral and benthic invertebrates from Roundwood Reservoir System were sampled. Oligochaetes and molluscs were the dominant organisms in the littoral and benthic areas Trichopterans and chironomids were the most abundant insect groups. Scuba diving samples reinforced that view. Other groups of macroinvertebrates were poorly represented. Vertical and horizontal hauls of zooplankton revealed that there were twelve species of zooplankton present. Daphnia hyalina Leydig and Bosmina coregoni Baird were the two dominant species.

Novel Combination for Self-Nanoemulsifying Drug Delivery System of Candesartan Cilexetil
...Show More Authors

Solubility problem of many of effective pharmaceutical molecules are still one of the major obstacle in theformulation of such molecules. Candesartan cilexetil (CC) is angiotensin II receptor antagonist with very low water solubility and this result in low and variable bioavailability. Self- emulsifying drug delivery system (SEDDS) showed promising result in overcoming solubility problem of many drug molecules. CC was prepared as SEDDS by using novel combination of two surfactants (tween 80 and cremophore EL) and tetraglycol as cosurfactant, in addition to the use of triacetin as oil. Different tests were performed in order to confirm the stability of the final product which includes thermodynamic study, determination of self-emulsificat

Implementation of a Proposed Load-Shedding System Using Altera DE2 FPGA
...Show More Authors

A load-shedding controller suitable for small to medium size loads is designed and implemented based on preprogrammed priorities and power consumption for individual loads. The main controller decides if a particular load can be switched ON or not according to the amount of available power generation, load consumption and loads priorities. When themaximum allowed power consumption is reached and the user want to deliver power to additional load, the controller will decide if this particular load should be denied receiving power if its priority is low. Otherwise, it can be granted to receive power if its priority is high and in this case lower priority loads are automatically switched OFF in order not to overload the power generation. The
