Motor & Gearbox The mirrors are required to rotate specific angles. To be able to achieve specific angles we need a stepper motor. The stepper motor is known to divide one revolution into equal steps which is our main requirements for the rotation of the mirrors. Figure ‎2-13: The Stepper Motor The following table shows the stepper motor specifications: Table ‎2-1: Stepper Motor Specifications Current 4.2 A Angle 1.8° Torque 8.34 N.m The desired torque calculated to withstand the mirror…

Lock and key is the interaction between a several materials that allows you to have control of accessing to physical properties, which was created by ancient Egyptians and from the information I have found, the first lock and key was created so they could keep their belongings to themselves. There are multiple models for security such as lock and key, padlock, safe and many more but I selected lock and key as the topic as I use it every day in my life from unlocking doors or even securing my…

As a company’s internal control cannot be considered effective if there are any material weaknesses, the audit must be planned in a way to obtain appropriate evidence that is sufficient…

Development of Feed Forward Control model in Simulink To implement feed forward control. Firstly, the transfer function of the linear DC Motor model has to be obtained. Actually in our case, the input of the plant is current so the transfer function of the mathematical model in ratio of angular velocity to current has to be obtained. It is given by: G(s)=Ω_1/I_a =R_A/K_M 1/(T_e s+1) where T_e=(J_meq R_A)/(K_m Cϕ) is electro-mechanical time constant. The feed forward control could be…

laws and regulation. The COSO framework does not only reflect the assessment of hard controls such as authorization, supervisory and segregation of duties, but also soft controls like the competence and professionalism of employees, integrity and ethical values of staff, the philosophy and operating style of management, and the efficiency of…

Thesis: Security is a big concern as hackers have reasons to obtain personal data for monetary gain. Network security risks are increasing and becoming more complex, resulting in many obstructions for information systems specialists. Security threats appear to accompany every new technology invented. I. Security Policy Guidelines Policies are considered highest level of documentation, from which the other major standards, procedures, and guidelines run. Security policy changes over time,…

situation and steal some of the assets of the company. So, this internal control will prevent fake transactions and stealing. I will determinate this by making a monthly match up of the inventory against the transactions of the month. 4- Access Controls: This refers to control the access to the accounting system of the company via passwords and ID verification. So, this will keep unauthorized people out of the system. This internal control will be determined by changing the password each month…

based on the company’s values, such as: respect, integrity, communication and excellence. However, this system devolved into being a means of intimidating employees and pressuring them to maintain above par performance (Thomas. The Rise and Fall of Enron). For fear of receiving a poor rating and being terminated, Enron’s employees strived to maintain performance excellence. This review system significantly diminished Enron’s tone at the top and the key values that trickled down through all…

safeguards for an organization's systems including user identification and password access, authentication, access rights and authority levels. These measures are to ensure that only authorized users are able to perform actions or access information in a network. Access control mechanism: As part of access control mechanism we are using MAC (mandatory access control mechanism) where users do not enjoy the privileges of deciding who can access their files. Here the operating system is the…
