DC motors are used extensively in industrial variable speed applications because of most demanding speed-torque characteristics and are simple in controlling aspects. This paper presents a DC motor speed controlling technique under varying load condition. The linear system model of separately excited DC motor with Torque-variation is designed using PID controller. A Matlab simulation of ...

Where the people are in the age of information revolution, exchange information and transport data effectively among various sectors of government, commercial, service and industrial, etc., the uses of a new databases model to support this trend has become very important because inability of traditional databases models to support it. eXtensible Markup Language (XML) considers ...

Many researchers have indicated that there are skills that are going to be essential for the future workforce. This paper helps identify these skills and the applicability of these skills to job performance of the future organization competing in a globalized environment. The paper provides insight into each of the ten listed skills and also ...

Increased profitability and exposure of enterprise’s information incite more attackers to attempt exploitation on enterprise network, while striving not to leave any evidences. Although the area of digital forensic analysis is evolving to become more mature in the modern criminology, the scope of network and computer forensics in the large-scale commercial environment is still vague. ...

In this paper, the authors present the results of a study that compared two think-aloud usability testing methods: the concurrent think-aloud and the retrospective think-aloud methods. Data from task performance, testing experience and usability problems were collected from 30 participants equally distributed between the two think-aloud conditions. The results suggest that while the thinking aloud ...

Computer forensics is the science of obtaining, preserving, documenting and presenting digital evidence, stored in the form of encoded information, from digital electronic storage devices such as computers, Personal Digital Assistance (PDA), digital cameras, mobile phones and various memory storage devices. All must be done in a manner designed to preserve the probative value of ...

Penetration Tests (PenTests) have gained recognition as a legitimate approach to identifying and then in theory, mitigating discovered weaknesses. The PenTest industry even has a Magazine (PenTest Magazine) and there are some tools out there that the user, as an Industrial Control Systems (ICSs) cyber security professional, ought to have in their tool set like ...

Identity theft through keyloggers has become very popular the last years. One of the most common ways to intercept and steal victim’s data are to use a keylogger that transfers data back to the attacker. Covert keyloggers exist either as hardware or software. In the former case they are introduced as devices that can be ...

In this paper, the authors demonstrate the route used for solving differential equations for the engineering applications at UAEU. Usually students at the Engineering Requirements Unit (ERU) stage of the faculty of engineering at the UAEU must enroll in a course of differential equations and engineering applications (MATH 2210) as a prerequisite for the subsequent ...

Digital signatures represent one of the most widely used security technologies for ensuring unforgeability and non-repudiation of digital data. The digital signature technique is generally used for validating or authenticating digital information. This paper presents two hardware ECDSA methods: synchronous and GALS based designs. A reduced power dissipation of hardware Elliptic Curve Digital Signature Algorithm ...
