An overview of ultrasound testing for lesion detection in human kidney

Ultrasound waves are commonly used to produce images of the human internal organs such as kidney. Most kidney cancers are found unexpectedly when patient have an ultrasound or scan for symptoms that turn out to be unrelated. Usually, the first test a medical doctor will do is an ultrasound scan, which is a real-time, moving test used to detect and differentiate between tumours, stones and cysts on the kidney. This paper presents the overview of ultrasound imaging for renal screening to detect renal lesions such as tumor, stone and cyst

Visual Signal Device (VSD) For Deaf Sports Athletics Malaysia

Previous study revealed that the advancement of technology has widen the potential for all individual including the disable to participate in any sport competition. Deaflympic and Malaysia Deaf Games,SOPMA respectively provide the opportunity for the deaf people to compete in sports event internationally and locally. From the literature, it is shown that deaf individuals have some visual-spatial advantages relative to hearing individuals. Hence, in this study, Visual Signal Device (VSD) being developed as a sight-based visual starting system for deaf sports athletes in track and field event. VSD system consist of a RGB LED panel, controller and the SEIKO brand electronic gun. The VSD system were explored to see its effectiveness during the sports for deaf people. The results show that, VSD successfully employed during the recent SOPMA 2018 in Perak, Malaysi

Application study on bubble detection in a metallic bubble column using electrical resistance tomography

Electrical resistance tomography (ERT) has been chosen as the field of study because of its advantages of being low cost, suitable for various kinds and sizes of pipes and vessels, having no radiation hazard, and being non-intrusive. In the development of ERT systems for metallic bubble column, prior knowledge of the fundamental process of the ERT system whilst improving the design and operation of the process equipment is essential. The fabricated electrodes need to be electrically insulated from the metal wall. Besides that, conducting boundary strategy is implemented to overcome the grounding effect of the metallic vesse

Optimal power dispatch of hybrid PV/diesel systems using heuristic bio-inspired algorithms

Generally due to the strategic equatorial region, Malaysia is advancing into solar energy as a replacement of alternative source for an electrical energy production to meet the escalation load demand. Thus, the integrated hybrid system like PVGenset set system are developed to generate power to meet load demand where it can be fitted into its local geography and others according to specification. However, this does not guarantee the hybrid system to generate power optimally as weather conditions (solar insolation, temperature and others) changes periodically and influence the power generation and the power dispatch to the load. Therefore, the hybrid system does not operate at the optimal state and without a proper dispatching controller it may lead to over stress one or the other hybrid system component causes frequent wear and tear with higher maintenance cost to the system. In order to curb this situation, the hybrid system requires a specific approach along with a controller to search and to dispatch the hybrid PV-Genset system generated power at the best potential optimal state. A Bio-Heuristic approach can be applied to determine the optimal power generation while a dispatch controller dispatches the electric hybrid power system to the load demand. The aim of this research is to implement the selected bio-heuristic approach such as Particle Swarm Optimisation (PSO) while Fuzzy Logic is used as a dispatch controller for a small scale hybrid PV-Genset system. The simulation of the hybrid PV-Gertset system modelling is simulated using two types of tropical weather conditions (sunny and rainy). From this research, simulation results are obtained and series of analysis is conducted using MATLAB/SlMULINK. Through the analysis, results have shown the contribution of each hybrid system component operates at the optimum level while power is dispatch to the load based on the hybrid system capability

Hardware development of an ultrasonic tomography measurement system

This research provides new technique in ultrasonic tomography by using ultrasonic transceivers instead of using separate transmitter-receiver pair. The numbers of sensors or transducers used to acquire data plays an important role to generate high resolution tomography images. The configuration of these sensors is a crucial factor in the efficiency of data acquisition. Instead of using common separated transmitter – receiver, an alternative approach has been taken to use dual functionality ultrasonic transceiver. A prototype design of sensor’s jig that will hold 16 transceivers of 14.1mm has been design. Transmission-mode approach with fan beam technique has been used for sensing the flow of gas, liquid and solid
