Abstract

This paper presents the outcome of a literature review that an overview of various types of antenna and metamaterial applicator performance towards cancerous tissue or cell for non-invasive hyperthermia cancer treatment (NIHCT) procedure. From the review, it shows that when LHM lens integrated with an antenna, focusing capabilities of the antenna towards the cancerous area can be improved. However, current applicators have a poor focusing effect when directed towards the actual tumor area. In conjunction with that, this paper proposes a new design of modified applicator that is microstrip antenna integrated with left-handed metamaterial (LHM) lens. The antenna termed microstrip-LHM (M-LHM) lens antenna is proposed for use in NIHCT. It is expected to improve the focusing capabilities of an antenna which is used to kill the cancerous area and thus improve the hyperthermia cancer treatment procedure success rate. In addition, this paper provides an overview of heating techniques used in hyperthermia to enhance focusing capabilities and a few metamaterial advantages that can improve the focusing effect and reduced the hot-spots. Specific Absorption Rate (SAR) will be investigated to evaluate the focusing abilities of the proposed applicator using the SEMCAD X Solver.

Abstract

Renewable Energy Act (RE Act) has been gazetted by the Malaysian Government in 2011 to encourage energy generation from renewable resources. Under Feed-in Tariff (FiT) scheme, solar PV has gained popularity due to its high FiT rates. However, the FiT scheme for solar PV has expired in 2016 and been replaced by the Net Energy Metering (NEM) scheme. The objective of this research work is to technically and economically analyze the solar PV system for a residential house under NEM scheme. The methodology involves gathering solar energy resource information and daily residential load profile, sizing PV array together with grid-connected inverter and then lastly simulation of the design system by using PVsyst software. Based on the results obtained, the amount of energy generated is higher when the capacity of solar PV system is increased. While most of the energy generated is exported to the grid, only up to 25% of load demand is supplied by the solar PV system. From economic aspect, the residential house does not need to pay the electricity bill due to the self-consumed of energy generated and profit gained from excess energy exported to the grid. From the environmental aspect, 2,434 kWh energy generated from renewable resource annually and consumed by the residential load has replaced the fossil fuel based power from grid. This value is equivalent to almost 1.7 tons of CO2 avoidance to the environment.

Abstract

Wireless sensor network (WSN) has attained wide adoption across various sectors and is considered to be key component of future real-time application such as BigData, Internet of things (IoT) etc. The modern application requires low latency and scalable real-time data access considering heterogeneous network. However, provisioning low latency real-time data access incurs energy overhead among sensor device. Clustering technique aided in providing scalability and minimizing energy consumption among sensor device. However, it incurs energy overhead among cluster head and sensor device closer to sink. To address, many optimization technique is been presented in recent time for optimal cluster selection. However, these technique are designed considering homogenous network. To address, this work presented low latency and energy efficient routing (LLEER) design for heterogeneous WSN. The LLEER adopts multi-objective function such asconnectivity, connection time, radio signal strength, coverage time, and network traffic for cluster head and hop node selection. Experiment are conducted to evaluate LLEER design shows significant performance improvement over state-of-art model in terms of network lifetime considering total node death, first node death, and loss of connectivity, communication overhead, and packet transmission latency. Proposed LLEER brings a good trade-off between energy efficiency, and latency requirement of future real-time application.

Abstract

Monitoring fault current is very important in power system protection. Therefore, the impact of installing Distributed Generation (DG) on the fault current is investigated in this paper. Three types of fault currents which are single line-to-ground, double line-to-ground and three phase fault are analyzed at various fault locations. The optimal location of DG was identified heuristically using power system simulation program for planning, design and analysis of distribution system (PSS/Adept). The simulation was conducted by observing the power losses of the test system by installing DG at each load buses. Bus with minimum power loss was chosen as the optimal location of DG. In order to study the impact of DG to the fault current, various locations and sizes of DG were also selected. The simulations were conducted on IEEE 33-bus distribution test system and IEEE 69-bus distribution test system. The results showed that the impact of DG to the fault current is significant especially when fault occurs at busses near to DG location.
