This paper presents an improved design of PV/T solar collector integrated with double pass air channel and a square stainless steel water tube. A theoretical approach and mathematical model have been suggested and developed to study the performance of the combined system. The equations governed from the steady-state one-dimensional energy balance analysis were analyzed using linear system solution...
Keystroke dynamics is the study to identify/authenticate a person based on his/her typing rhythms, which are inferred from keystroke events like key-press and key-release. A lot of research work has been done in this field where the researchers have used either only alphabetic or alphanumeric or only numeric inputs. In this paper we address the question — What is the best possible numeric input for...
The present study aims to explore the correlation of TUA (Teach, Use, Assess) and CDIO (Conceive-Design-Implement-Operate) implementation in the field of engineering education. Outcome Based Education (OBE) is adapted to identify and enhance the clarity of outcomes in a subject or course thought. To ensure that the target of OBE is well achieved, the CDIO is implemented and is analyzed through the...
In the recent days, the facial biometric system is widely used for the mobile payments and other surveillance systems. Its popularity is going to be increased because of its easiness to use and also it is user friendly. But the main problem in this system is its vulnerability to the spoof attacks made by 2D or 3D face masks or printed photographs. In order to guard against face spoofing, the anti-spoofing...
This paper addresses p-processes single processor scheduling problem with a common deadline, to minimize the total execution time and reduce the penalty costs. Process scheduling is one of the most essential factor on which the efficiency and the performance of the work done by the CPU depends. Earliness and tardiness of the processes degrades the efficiency of the processor as they carry penalty...
Thresholding is one of the most frequently used methods in image segmentation. Fuzzy entropy thresholding approach has been widely applied to image thresholding. Such thresholding approach used two parametric fuzzy membership functions for fuzzy partitioning of the image. In this paper, Teaching-Learning-based Optimization (TLBO) algorithm is used to search an optimal combination of parameters of...
This paper presents a system design of sustainable thermoelectric power generator based on solar concentrator and latent heat storage as a passive heating and cooling sources. The advantage of using thermoelectric cells is the ability to operate at high temperature (∼150°C) environment with no moving parts which make it favourable for solar concentrating applications. In this present experimental...
The use of parabolic solar cooker in regions with high solar radiation like Malaysia promises an alternative for cooking other than the fossil fuels and wood. This project presents the development of a small parabolic solar cooker using sunlight as its energy source for cooking. The parabolic solar cooker uses mirror glass to reflect the radiation from the sun to a focus point. The heat from this...
Salinity-gradient solar pond (SGSP) is capable of storing heat at temperature up to 80°C. The temperature difference between the upper convective zone (UCZ) and lower convective zone (LCZ) of a SGSP can be in the range of 40°C – 60°C. This temperature difference can be used to power thermoelectric generators (TEG) for electricity production. This paper present results of a TEG system designed to be...
This paper proposes a new Modular Multi-level Converter (M2LC) topology, which is based on an Inductive Power Transfer (IPT) technology. The modified M2LC topology employs an IPT system to control the capacitor voltage of each module, thereby decoupling the capacitor voltage balancing control from the load current control. The IPT system maintains the capacitor voltages within a narrow band around...
A Pt20/C80 nanocomposite was synthesized by maintaining Pt content at 20% on an activated carbon support (80%), resulting in excellent Pt nanoparticles dispersion and catalytic performance towards direct electro-oxidation of glucose and formic acid. The compositional, structural and morphological characterization of Pt20/C80 were examined using transmission electron microscopy (TEM), thermogravimetric...
This work investigates the effect of using palm oil based additive on four stroke engine performance and exhaust emission. This investigation focused on the comparison of performances of an internal combustion engine fitted with the fuel additive. Performance tests were conducted for, fuel consumption, engine torque and engine power, while exhaust emissions were analyzed for carbon monoxide (CO),...
This paper describes the first phase of the development process of this project. There are two phases involve in this research work. In the first phase, PROTUES simulation tools were used to design, study and analyze the proposed research work. Results from the simulation will be use as reference to re-design and develop the real-time hardware-based system. In the second phase, the hardware will be...
