<em>Internal control is a process carried out by the company to provide adequate guarantees for achieving control objectives. The objective of this Research is to find out the current internal control system that is applied at PT Pegadaian (Persero) Kaliwungu Branch Service in the process of granting credit. The next objective is to identify whether the components of internal control applied are according to COSO. The data used are qualitative data, primary data, and secondary data. The methods of collecting data are interview, observation, and questionnaire. For writing the Research uses descriptive and exposition methods. There are five components of internal control according to the Committee of Sponsoring Organization (COSO), they are Control Environment, Risk Assessment, Control Activities, Information and Communication, and Monitoring. The results of the discussion in the Research shows that the application of the internal control system for granting credit at PT Pegadaian (Persero) Kaliwungu Branch Service is in accordance with COSO internal control component, but the Control Environment and Control Activities has not been fully implemented.</em>

This study aimed to measure the efficiency of employing the internal control components based on COSO framework to transparently carry out tasks and services, ensure integrity and enhance quality and efficiency, so as to contribute to promoting the adoption of internal control components based on the COSO framework, applying them and analyzing their efficiency in performing tasks transparently, ensuring integrity and enhancing quality and efficiency, particularly with the Amman`s Municipality efforts to create a directorate that operates the internal control while ensuring the integrity of the proceedings, carrying out tasks and services transparently and boosting citizen's confidence in the Greater Amman Municipality resolutions. One of the main findings of the study would be in the fact that the independent study variables represented in the internal audit based on the COSO framework has a highly positive impact in performing tasks transparently to ensure integrity, boost quality and efficiency at the Greater Amman Municipality. Results show that the communications systems component was the most highly applicable, followed by the follow-up and control procedures and activities, whereas the control environment came third, followed by risks and response procedures identification and assessment, and finally came the appropriate follow-up component in the fifth place.

In this paper, fault-tolerance characteristics of a reconfigurable tilt-rotor quadcopter upon a propeller failure are presented. Traditional quadcopters experience instability and asymmetry about yaw-axis upon a propeller failure but the design and control strategy presented here can handle a complete propeller failure during flight. Fault-tolerance is achieved by means of structural and flight controller reconfiguration. The concept involves conversion of a tilt-rotor UAV into a T-copter. The dynamics and control of the tilt-rotor quadcopter are presented for ideal flight condition and for the reconfigured system in case of propeller failure. Analytical solution for trim flight conditions yielding zero angular rates for the UAV is derived. It has been shown that the structurally reconfigured UAV is controllable and completes the flight mission without much compromise in flight performance. The controllability and observability analysis of the reconfigured system is shown by state space formulation. The flight controllers for both dynamic models are analyzed and the applicability of the proposed concept is presented by propeller failure simulation during the way-point navigation.
