This paper presents the performance evaluation of an active vibration technique in suppressing human hand tremor. A PID integrated with fuzzy logic controller is proposed to control a linear electromagnet actuator and then applied onto a four Degree-of-Freedoms (DOFs) biodynamic model which emulate a Parkinson Disease (PD) hand. Heuristic method is employed in searching for appropriate parameters...
Electro Pneumatic Trainer for educational applications is developed as supporting tools towards the existing typical teaching and learning process. The main objective is to improve the learning outcome towards student's cognitive knowledge and practical skill where the existing teaching and learning for electro pneumatic courses conducted in the classroom without emphasizing on simulation and complex...
Lately, the idea of indoor vertical farming has caught a wide attention throughout the world either for domestic or commercial purposes. This is one of the ideal decisions in modern agriculture technique when the land area for the plantation activities has become the major concern especially in the urban area. However, certain factors must be considered to mimic the actual condition of the outdoor...
Fault Detection and Identification (FDI) monitor, identify, and pinpoint the type and location of system fault in a complex multiple input multiple output (MIMO) non-linear system. A Quadrotor robot is used to represent a complex system in this study. The aim of the research is to construct and design a Fault Detection and Isolation algorithm. This dynamic model is based on the first principles of...
This paper deals with an analysis of intermittent observations for mobile robot localization with Fuzzy Logic approach. Mobile robot can easily lost its sight during environment observations due to several factors such as sensor faulty, and dynamic conditions. This can lead to erroneous estimation and the mobile robot become uncertain about its position. As a solution to this issue, this paper proposed...
Subjective evaluation of the abnormalities in dental images faces a few challenges such as low contrast. The problem arises due to the fix regulation of small X-ray dosage. Thus there are applications of image enhancement on the dental images and it is an acceptable technique to improve image quality and better diagnosis. Low contrast images could hinder the subjective evaluation and contribute to...
The Quran is a script consisting of 114 Surah. The Quran is known to have positive effects on human, aids the stress healing process. Each Surah is provided for a different understanding and meaning of its own. This paper investigates the subject's reaction towards listening to two different Surahs. The electroencephalogram (EEG) machine was used to observe and record the subject brain activity. By...
People are very vulnerable in case of natural disasters. Power grid destruction is a common disaster in these situations. Numerous costumers might easily lose access to electric power and this condition can continue for a long time after the catastrophe. Emergency shelter after occurrence of disasters is usually offered by organizations or governmental emergency administration departments, as a comeback...
Overcurrent relay is an important relay used to protect transmission and distribution feeders, transformer, bus coupler etc. It can be used as main or backup protection relays. The modeling of overcurrent relay and other protection relays is important in the research on the effects of network parameters and configurations on the operation of these relays. This research deal with modeling and simulation...
Over the past decade, pneumatic muscle actuator (PMA) has been in the limelight and receiving much attention not only in the field of industrial application as well as in prominent research areas such as robotics and biomedical engineering. The uprising can be accorded to the many advantages that PMA offers such as inherent compliant safety, low maintenance and powerful. However, PMA has yet to emerge...
One of the high efficiency motors that were introduced to the industry in recent times is Line Start Permanent Magnet Synchronous Motor (LS-PMSM). Fault detection of LS-PMSM is one of interesting issues. This article presents a new technique for broken rotor bar detection based on the values of Mean and RMS features obtained from captured start-up current in the time domain. The extracted features...
This paper presents an integration of a low cost microcontroller with a power converter for controlling the output voltage. Here, it will benefit the UTHM final year student in order to apply what have been taught during Power Electronics subject in Year 3. The power converter that has been developed is the zero voltage switching (ZVS) with inverter voltage control mechanism. As for the microcontroller...
Over the last three decades, electrical and electronic industry is the leading industry in Malaysia in terms of export income and employment opportunities. However, to keep up with its international competition, Malaysia requires introducing novel improved products in this field. In this respects, using the natural resources available in the country is a fascinating option for developing electrical...
The research presented in this paper is carried out to investigate the performance of a suspension systems either an active or passive type. Controllers that are used in this study are proposed fuzzy logic controller and proportional integral derivative controller as a benchmarking comparison. The simulations in this research have been carried out using Simulink of MATLAB. The parameters in the simulation...
In this paper, a 3D scene reconstruction by using stereo vision is presented. Stereo camera parameters from the camera calibration process and disparity map are two important parameters to obtain an accurate result for the 3D reconstruction. 3D reconstruction process generates the coordinates of world points (point cloud). From the information of the point cloud, the interested object is segmented...
