An IEEE 34 node test feeder is constructed by using DIgSILENTPowerFactory. The load flow results are more or less as given by IEEE. Dynamic and static photovoltaic system, dynamic and static wind generator are modeled. Distributed generators are modeled in the setting in a way, such that load flow calculations can be carried out when they are interfaced to IEEE 34 node test feeders system. Different...
Multi-Touch is a technique that provides user the parallel interaction with the Graphical User Interface. This paper presents innovative ideas on the development of hardware and software applications of a multi-touch system. Besides that, Frustrated Total Internal Reflection (FTIR) method and Rear Diffused Illumination Reflection (RDIR) method have been integrated to improve the performance and accuracy...
This paper introduces an image fusion technique on a gated image. Gated imaging is a powerful technique to capture images in turbid condition. By controlling the time delay of the shutter to capture the returning light, we can obtain the image at different depth. Modular transfer function (MTF) is used to evaluate the quality of the gated images. Images with useful information (clear and sharp objects)...
This paper deals with the monitoring, control and protection of a single phase induction motor. The power to the motor is controlled using a triac. In this work, the potentiometer which determines firing angle to the triac is controlled using a stepper motor. The system provides a simple yet a practical technique for a closed loop system. LabVIEW was used for system monitoring and industrial components...
Operation of the rotary reluctance machine is highly affected due to the sequential attraction-repulsion principle of the adjacent phase excitation. The problem has been identified and addressed by various researchers in the past decades. Effective magnetic design is one way of minimizing the effect. However it is tedious and time consuming as the design procedure involve higher analytical derivation...
The paper investigates the STATCOM system based on five-level cascaded inverter controlled using carrier-based pulse width modulation (CB-PWM) technique. In this work, the STATCOM is controlled to provide only the reactive power compensation at the point of common coupling (PCC) when an RL load is connected to the power system at different lagging power factors. The rotating switching scheme is employed...
This paper presents the improved design of a Coanda Effect Test Bench (CoETB) and its experimental data. The CoETB is primarily setup to investigate the authors' hypothesis that a steerable Coanda effect can be used for flight directional control. The design is currently based on the Unmanned Aerial Vehicle (U.A.V) manufactured by GFS Projects Limited or known as the GFS-UAV. The CoETB experiment...
Vision system could enhance the mobile robot applications and features. However, the vision system could also improve the overall system of mobile robot so as to contain higher complexity with the purpose to be reliable, effective, robust and fast enough to achieve their goals. This paper will present a simple yet reliable monocular vision system in the mobile robot to increase their capabilities...
The new advancement in technology made cell phone as a smart phone with highly computing capabilities and low processing power. Currently, achieving real-time image processing routines such as convolution, edge detection, thresholding and some of complex media applications is a challenging task with the smart phone, because of limited memory and power constraints. An open software framework, Symbian...
This research investigates the possibility of differentiating slaughtered and non-slaughtered goat meat using capacitor. The use of dielectric spectra to distinguish slaughtered and non-slaughtered meat in goat muscle during postmortem period was evaluated. The changes in dielectric properties during meat ageing were analyzed in terms of permittivity for each meat test. For these purposes, capacitance...
Nowadays, Power Line Communication (PLC) using pre-established Power Lines (PL) becomes more attractive for high data transmission technology. With the development of this technology utilizing distribution line, the medical data such as human Heart Rate (HR) can be transmitted over the power line channel. This paper presents a case study of HR Monitoring System (HRMS) involving the use of PLC as a...
The latest trend and technology buzzword in the IT industry is cloud computing. By leveraging on cloud computing's characteristics such as resilience, fault tolerance and high availability, a new generation of cloud based security solutions has emerged. This paper specifically looks at the notion of merging spam filtering with cloud computing and is one of the earliest studies done in this area. Following...
The classification of different types of mental tasks is an active area of research that seems to be ever expanding. This field is gaining interest from researchers all over the world. This study is intended to utilize the Stockwell transform (ST) to investigate the classification accuracy of five different types of mental tasks. A well known electroencephalogram (EEG) database (Keirn and Aunon database)...
Physco-physiological conditions like stress and emotional state may affect human's speech production. Different techniques have been proposed such as facial expressions, speech production variation, and physiological signals to detect the emotional/stressed states of a person. For past 2 decades, the determination of an emotional/stressed state through speech has been undergone substantial research...
