This paper investigates the capability of Acoustic Energy Harvesters (AEH) in generating electricity to minimize electricity consumption. In AEHs, piezoelectric materials convert mechanical stress into electrical energy. It generates electricity with the application of stimulus such as pressure or sound. This paper reports on the study of a commercial passive piezoelectric transducer effect on an energy harvesting circuit. The energy generated could be used in low power charging applications such as mobile electronic gadgets. The methodology employed in this study is via the energy harvesting circuit based on Piezoelectric Acoustic Energy Harvester (PEAEH) technique. The study advocates the use of renewable acoustics energy supply system to support green energy applications. One of the strengths of this system is that it could withstand noisy environments such as in industrial areas, train stations, bus terminals or busy roads. Another advantage is that it could create a new service for the public to charge their mobile devices conveniently. Finally, the result of the study contributes in waste minimization of electrical energy and electrical bills.

Dye-sensitized solar cells (DSSC) belong to the third-generation solar cells and have been actively investigated due to their low cost and ease of fabrication. Dye-sensitized solar cells (DSSCs) based on titanium dioxide (TiO2) nanoparticles in mesoporous oxide have been intensively investigated since the first high efficiency cell was reported by O'Regan and Grätzel in 1991. In this paper, the effect of composition of micro/nano powder size TiO2 nanostructured in the mesoporous oxide layer was studied. The micro/nano powder, titanium dioxide have been successfully deposited on the transparent conductive oxide substrate using the screen printing technique. The effect of composition of (100% nanopowder), (75% nanopowder/25% micropowder), (50% nanopowder/50% micropowder), (25% nanopowder/75 micropowder and 100% micropowder) size of TiO2 nanostructured being studied. The deposited Titanium Dioxide films were characterized by field emission scanning electron microscope (FESEM) and Solar Simulator. The best efficiency of 3.46% under AM 1.5 was attained with a composition of (50% nanopowder/50% micropowder). The properties of TiO2 in term of thickness and total of adsorbed dye are not the only factors which have an influence on the overall conversion efficiency of dye sensitized solar cell. The combination of high light scattering and moderate surface area able to improve the performance of the dye sensitized solar cell.
染料敏化太阳能电池(Dye-sensitized solar cells, DSSC)属于第三代太阳能电池，因其成本低、易于制造而受到人们的积极研究。自1991年O'Regan和Grätzel报道了第一种高效电池以来，基于介孔氧化物中二氧化钛(TiO2)纳米颗粒的染料敏化太阳能电池(DSSCs)得到了广泛的研究。本文研究了介孔氧化层中微/纳米粉末级TiO2纳米结构的组成对其性能的影响。采用丝网印刷技术成功地将微纳粉末二氧化钛沉积在透明导电氧化物衬底上。研究了(100%纳米粉)、(75%纳米粉/25%微粉)、(50%纳米粉/50%微粉)、(25%纳米粉/ 75%微粉和100%微粉)组成对TiO2纳米结构的影响。采用场发射扫描电镜(FESEM)和太阳模拟器对制备的二氧化钛薄膜进行了表征。当纳米粉/微粉比例为50%时，在AM 1.5下的效率为3.46%。TiO2在厚度和吸附染料总量方面的性能并不是影响染料敏化太阳能电池整体转化效率的唯一因素。高光散射和中等表面积的结合能够提高染料敏化太阳能电池的性能。

In this paper, a characterization and comparison between the effects of Electron irradiation on the gain of low noise amplifiers (LNAs) implemented Silicon-Germanium (SiGe) Heterojunction Bipolar Transistor (HBT) and Gallium-Arsenide (GaAs) HBT technologies was carried out respectively. Previous studies have shown that the properties of SiGe and GaAs HBT's are very tolerant to gamma, neutron, and proton irradiation without additional radiation hardening. Nowadays, commercial on the shelves (COTS) LNAs have been used in CubeSat communication system lunched in Low and Medium Earth Orbits. It therefore believed that the electron radiation in space may degrade the LNA's performance and lead to its failure. This is shows the importance of such investigation in evaluating and comparing the performance of the GaAs and SiGe LNAs which represent an important module in the front end of the communication receiver system. Two samples of GaAs and SiGe have been selected: the ADL 5523 GaAs and the SiGe BFU730F LNAs which are respectively cover a frequency range of 400MHz to 4 GHz and 2.3 to 2.7 GHz. Samples were irradiated with 3 MeV Electron doses ranging from 50 kGy to 250 kGy in the Electron Beam Irradiation Centre (Alutron), Nuclear Malaysia Agency. Results measurement have been carry out in the RF Laboratory in the faculty of engineering (IIUM), using the vector network analyzer 50 GHz. The results indicate that both SiGe and GaAs HBT technologies have been affected by the electron Irradiation.

Important aspect of antenna array optimization is to validate the obtained results in a practical environment. This paper presents the practical validation of time modulated linear antenna arrays (TMLAA) with optimized radiation pattern using EM simulator. The optimization is done by using particle swarm optimization with improved inertia weight (PSOIIW) algorithm approach. Computer simulation technology-microwave studio (CST-MWS) is used as EM simulator. Dipole element is taken as elemental pattern for pattern multiplication with the array factor (AF) of isotropic linear antenna array, which gives the equivalent results of TMLAA of dipole elements. Half wave dipole has been designed, with its resonant frequency 2 GHz. Different sets of antenna array along with MATLAB simulation results have been shown in this paper.

Hardware information security has become an important structure and application metric. The existing hardware security has a well designed security measures but it only address a certain amount of rising security requirements and is slow for a lot of the emerging security primitives Physical true random number generators (TRNGs) appear to be critical components of many cryptographic systems. Random number generators are used to combat this problem by producing different and unique identification for each user in a network. This paper analyzes on how memristors can be implemented in ring oscillator (RO) based random number generators and how the random number generator measure randomness and its value. The proposed random number generator produces a randomness value of 25.2μ.

Differential capacitive sensing technique has gained popularity in capacitance measuring system due to its high symmetrical implementation, easy to be implemented using discrete components and has a characteristic of high linearity in its system. However, very few work has reported on the differential CVC system that is able to operate at a high frequency operation especially when using discrete method. In this work, a differential CVC is proposed using discrete single supply, suitable for energy harvesting and WSN application. The method has emphasised on the rectifier current behavior analysis of the capacitive sensing circuit. Using this method, sensitivity of 0.04933 mV per 1 ƒF capacitance change is achievable with low power consumption of 3.83 mW. The proposed method has also shown high linearity of R-squared value 0.99788 between 5 and 9.5 pF capacitance change. Finally, the recorded DC output voltage is in the range of 1.6505 to 1.8725 V output with working frequency of 200 kHz operation.

This paper presents feature extraction techniques using shape-based features and Zernike moments combined with colour attributes. Features are extracted to classify 30 different fasteners which differ in term of size and colour. Red, green and blue channels of the images are used to extract the features for the colour based technique. For Zernike moments' technique, various orders and repetitions are used as descriptors. In term of shape-based technique, various pixel-based measurements are used such as major axis length, perimeter and solidity. Single hidden layer feed forward artificial neural network is used as the classifier. The experimental result shows shape-based technique combined with colour features yields a good result of 99.89% correct classification accuracy.

This paper describes in details the IPTV (Internet Protocol Television) system. Also, measurement methods of the QoS parameters are analyzed, debating a practical application for evaluation of IPTV traffic parameters. QoS (Quality of Service) parameters such as IP Packet Transfer Delay (IPTD), IP Packet Delay Variation (IPDV) and packet loss Ratio (IPLR). The recent Internet is working under TCP/IP (Transmission Control Protocol/Internet Protocol) protocol stack and is based on two main fundamentals, which are: network offers only one class of service named best effort service, and network resources are overprovisioned as possible in order to minimize packet losses and packet delays. The Internet providers aim to provide packet transfer to users as fast as possible, However they are far from guaranteeing, so called, rigid quality of service (QoS) that is measured by the maximum allowable values of such parameters as IPTD, IPDV and IPLR. Furthermore, network abilities of packet transfer determine the range of applications which users may use with appropriate satisfaction these applications such as IPTV. ANYLOGIC Professional6 software was used to analysis the QoS parameters for IPTV and our results help in critically analyzing QOS parameters for IPTV applications.

In the following couple of years, an alternative for the 4G and its derivatives like the LTE-A is inventible. The demands and challenges must be envisaged and addressed to meet the desired objectives of the upcoming 5G mobile networks which are resembled by significant increasing in capacity, improved data rate, low latency, and better quality of service. To achieve these objectives, radical enhancements and improvements have to be made in cellular network architecture and the antenna configuration that is used for this purpose. This paper presents the results of a 5G cellular network phased array antenna with millimeter wave beamforming at 28Hz.

The demands and challenges must be envisaged and addressed to meet the desired objectives of the upcoming 5G mobile networks which are resembled by significant increasing in capacity, improved data rate, low latency, and better quality of service. To achieve these objectives, radical enhancements and improvements have to be made in cellular network architecture and the antenna configuration that is used for this purpose. This paper presents the results of a 5G cellular network phased array antenna with millimeter wave beamforming at 28Hz.
