Modeling Qos Parameters of Voip Traffic with Multifractal and Markov Models
Research Output | Dar Al-hikmah Library | IIUM Only

In this paper, we analyze the jitter and packet loss behavior of voice over Internet protocol (VoIP) traffic by means of networks measurements and simulations results. As result of these analyses, we provide a detailed characterization and accurate modeling of these Quality of Service (QoS) parameters. Our studies have revealed that VoIP jitter can

Spikes Blocking and Surge Protection
Research Output | Dar Al-hikmah Library | IIUM Only

In order to ensure a constant voltage source, we employ line regulation, load regulation and ripple rejection. These are often small deviations in the input voltage. A spike or surge is a sudden large deviation in the circuit that usually only lasts for a very short period of time, for example lightning surges. This characteristic means that regula

full-Wave Rectification of a low-Voltage Source
Research Output | Dar Al-hikmah Library | IIUM Only

AC voltage supplies are commonly available in our residential or induSlIial envilllfllllent. however in consumer electronics the supply required is always DC voltage ~upply. Many devices employed for sensitive electronic operations. such as fine-luning and control. require an almost perfect DC voltage level which is normally obtained from Ihe avail

Voltage Supply and Voltage Regulation
Research Output | Dar Al-hikmah Library | IIUM Only

A stable voltage supply is important for the proper operation of electronic devices. Stability is characterized by the ability of the voltage output to stay constant and ripplefree regardless of how much load is connected to the circuit. There is a brief discussion on how much inaccuracy is caused by voltage supplies which are prone to voltage fluc

Invariance of an Extended Technology Acceptance Model Across Gender and Age Group
Research Output | Dar Al-hikmah Library | IIUM Only

In this study, we examined the likelihood of a TAME (extended technology acceptance model), in which the interrelationships among computer self-efIicacy, perceived usefulness, intention to use and self-reported use of computer-mediated technology were tested. In addition, the gender- and age- invariant of its causal structure were evaluated. The da

Mencermati Doktrin dan Ciri-ciri Fahaman Pluralisme Agama
Research Output | Dar Al-hikmah Library | IIUM Only

Barangkali tidak banyak yang menyadari, apalagi mempertanyakan!, bahwa indoktrinasi sebuah doktrin "agama baru" yang bernama Pluralisme Agama ini telah dan sedang berlangsung secara intense, well-planned, dan sistematik di seluruh segmen masyarakat dunia yang nyaris tanpa sempadan ini. Hal ini dapat disaksikan melalui berbagai mass media, e

h-Inf Robust Controller for Autonomous Helicopter Hovering Control
Research Output | Dar Al-hikmah Library | IIUM Only

Among the major challenges associated with the deployment of autonomous small scale helicopters in civilian UAV applications is the requirement for reliable control scheme. This is due not only to the inherent complexity of the helicopter dynamics, but to the vulnerability of the system to various uncertainties as a result of difficulty in obtainin

Optimizing of Pid Controller for Flexible Link System Using a pareto-Based multi-Objective Differential (Pmode) Evolution
Research Output | Dar Al-hikmah Library | IIUM Only

The conflict between the transient performance of the link position and tip vibration in a flexible link system has made the control of such system a challenging task. The system is required to obtain a fast transient position response together with minimal tip vibration. This can be viewed like many other real-life control problems as a multi-obje

Power Supply Interference in Smart Sensor Microcontroller Interface
Research Output | Dar Al-hikmah Library | IIUM Only

Signal conditioning circuits otherwise referred to as sensor interface play important roles in data acquisition systems especially with microcontroller based systems. They are employed for signals conversion or translations to squeeze the acquired signal into a desirable range easily acceptable for the microcontroller. Many interfaces (signal condi
