This paper presents a rectangular microstrip patch antenna with EBG structure. The combination of the rectangular microstrip patch antenna fabricated on the top of the substrate Rogers RO3003 with Electromagnetic Band Gap (EBG) structures at the ground plane is proposed to investigate the metamaterial characteristics in antenna design for satellite application. The patch antenna along with the EBG structure is designed to resonate at 7.3 GHz. Simulations and measurements have been carried out to verify the performance of EBG structures in patch antenna. All the simulation and measurement work is done by using Computer Simulation Technology Microwave Studio (CST-MWS) and Vector Network Analyzer (VNA) respectively. Metamaterial characteristics which exhibit negative permittivity and permeability of the proposed EBG structures have been verified using Nicolson-Ross-Weir (NRW) method. As a result of combining the rectangular patch with EBG structure, the bandwidth of the antenna has been increased by 39.63% and the size of the antenna reduced by 22.38% compared to the antenna without EBG. The return loss also met the specification of -10 dB cut off.

There has been limited study and research in Arabic phoneme among Malaysians, hence making references to the work and research difficult. Although there have been significant acoustic and phonetic studies on languages such as English, French and Mandarin, to date there are no guidelines or significant findings on Malay language. In this paper, we monitored and analyzed the performance of multi-layer feed-forward with back-propagation (MLFFBP) and cascade-forward (CF) networks on our phoneme recognition system of Standard Arabic (SA). This study focused on Malaysian children as test subjects. Focused on four chosen phonemes from SA, which composed of nasal, lateral and trill behaviors, i.e. tabulated at four different articulation places. Highest training recognition rate for multi-layer and cascade-layer network are 98.8 % and 95.2 % respectively, while the highest testing recognition rate achieved for both networks is 92.9 %. 10-fold cross validation was used to evaluate system performance. The selected network is cascade layer with 40 and 10 hidden neurons in first hidden layer and second hidden layer respectively. The chosen network was used in the GUI designed for developing recognition system with user feedback.

With the rise of mobile phones and smart phones as a livelihood necessity in recent years, a security engineer's responsibility is to utilize this feature to further secure the existing infrastructure. Mobile phones can attach a geolocation to the phone owner. This geolocation can be located precisely through GPS or less precisely using network triangulation. Smart phones nowadays usually have GPS capabilities but not all phones possess this feature. GPS is precise but consumes more battery life. Triangulation uses nearby cell towers to provide the geolocation and functions at its peak in urban areas with the minimum of three cell towers. This geolocation information can be used to authenticate the clients seamlessly or to complement One Time Passwords (OTP). Volatile passwords have become popular in the past years as well. This is due to their secure nature of not maintaining any stored passwords. OTP complemented with the geolocation information acquired earlier can further improve the security of any mobile client. In this paper a prediction algorithm is evaluated and then a more accurate and faster algorithm is introduced and evaluated.

The demand for mobile communication systems has dramatically increased in recent years. New concepts and methods, which can optimally exploit the limited resources, are necessary which required the need for new Technologies to satisfy that demand. Smart antenna system is one of those, which combats the co-channel interference and maximizes the user capacity of mobile communication system By shaping and locating the beam of the antenna on the mobile or the target thus decreasing interference to other users. It is now recognized by its higher user capacity in 4G wireless networks by efficiently reducing multipath fading. This paper presents a tool for the modelling, analysis and simulation of Smart Antenna System direction-of-arrival (DOA) estimation and adaptive beamforming needed in the design of smart antenna arrays for wireless mobile communications. The performance of smart antenna system had been studied for some linear and planar array antennas with different numbers of elements. Starting by transmitting the signal through smart antenna system, receiving it and calculating its BER under some 3G Network parameters environment.

With the emergence of nanotechnology, the desire for more shrinkage of electronic devices is gaining a wide spread acceptance. A compact nano laboratory on single chip is one of the devices employed under this scenario, thus, for the transition of microgap electrode to be successful there is a need for the pattern to be precisely transferred to sample wafers during fabrication. The article demonstrates the initial strategy for fabrication of microgap electrodes using conventional photolithography technique coupled with wet etching process. The study demonstrates the excellent strategy for fabrication of microgap electrodes by using polysilicon sample wafer and positive photoresist.

In this paper, a new partial H-plane filter with half-wavelength resonators and periodic slow-wave structure is presented. The proposed filter makes use of the slow-wave effect to improve the frequency characteristics and considerably reduce the filter length. Using partial H-plane waveguides reduces the filter's cross section to one-quarter of that of a conventional E-plane filter. Although because of their compactness, the insertion loss of the proposed H-plane filters is larger than that of the E-plane filters, they have lower cost and are mass producible. Also by using the periodic slow-wave structure the stop-band slope has been improved and the length has been reduced by 22 percent. These partial H-plane filters have been designed along with coaxial to partial H-plane waveguide transition.

Electrical equipments mainly use polymeric material as insulation due to its characteristic of having high resistance to repel/retard electrical discharge attack, thermal conductivity, tree growth, and chemical cavities. Recently, polymer composite has been modified with addition of nano-sized filler instead of the conventional micro-sized filler. It was found that addition of nano-sized filler in polymer composite provides better characteristic if they are prepared and fabricated properly. The interfaces of the filler plays role in determining the behaviour of the polymeric insulation. Addition of different types of filler i.e. silica (SiO2), titania (TiO2), alumina (Al2O3), zinc oxide (ZnO), magnesium oxide (MgO), clay, etc. also gives different dielectric behaviour to polymeric insulation. This paper provides a review on the effect of particle size and types of filler on polymeric material insulation. In attempt to identify the characteristic of these fillers on polymeric insulation, partial discharge (PD) amplitude, erosion depth, breakdown strength, glass transition temperature, and scanning electron microscopy (SEM) images of polymer composite samples are studied. The role of interfaces is also explained.

Disturbances in a power system such as line switching and sudden removal of faults may cause instability which lead to the power swing phenomenon. During a power swing, the mal-operation of distance relay is among the problem which needs to be solved. In the case of a power swing, a distance relay is designed to block detection to avoid wrong interpretation of relay current signals. However, this blocking scheme proves to be unreliable as it could block the trip signals when a genuine fault occurs in the system during a power swing. Hence, it is vital to develop a proper fault detection technique during a power swing to avoid such circumstances. This paper presents a detection technique to detect symmetrical faults during a power swing based on the time frequency transform known as S-Transform. To ascertain validity of the proposed scheme, it was verified with the IEEE 14-bus system and simulation results showed that the proposed technique was able to detect symmetrical faults occurring in the power system.

In recent decades, the presence of photovoltaic (PV) systems is increased to provide power for local or remote loads. However, when a large PV system connects to the distribution network under variable weather conditions, it may cause severe problems for power system components. This paper presents a dynamic power quality analysis on a grid-connected PV system in a distribution system subjected to different weather conditions. A 1.8 MW grid-connected PV system in a radial 16 bus test system is modelled and simulated under varying solar irradiations using the Matlab/Simulink software. The simulation results proved that the presence of high penetrated grid-connected PV systems can cause power quality problems such as voltage rise, voltage flicker and power factor reduction.
