Specific odd harmonics can be mitigated by operating the semiconductor switches in H-bridge inverters at optimized switching angles of the PWM signals. These switching angles can be achieved by deriving a number of nonlinear equations using Selective Harmonic Elimination Pulse Width Modulation (SHE-PWM) method. Modulation index (m) is a significant parameter used to control the amplitude of the fundamental output voltage of DC-AC inverter. By changing the value of modulation index the Total Harmonics Distortion (THD) also will change. In this paper, the performance of single phase full-bridge inverter using SHE-PWM scheme with varying the modulation index is evaluated. In order to achieve a minimum THD, a different number of nonlinear equations are used to calculate the switching angles. The performance of a single phase unipolar inverter is simulated in Matlab.

Wireless Power Transmission for powering up of the electronic gadgets, electric vehicles, and biomedical implants is being researched heavily these days. It has been proving to be the only in the electric vehicles battery charging systems, as it is hassle free, more efficient and easy to install. In many-to-one as well in one-to-many power transfer selective resonant technique plays a vital role. The many-to-one principle is mainly in the battery charging system of electric vehicles. This paper explores the source-to-load-coil (one-to-one and one-to-two) links using the magnitude of the reflective impedance (ZRef) as a parameter estimating the power transfer efficiency. The analytic expressions and simulation results have been explored in this analysis, showing the effect of resonant and load matching.

These paper introduce data transmission system that been developed and demonstrated for two toys vehicles based on light emitting diode (LED) which is highly reliable for short distances communication. Communication protocol A and B has been deployed for data transmission and the feasibility of both protocols is tested. Data transmission performances such as photo-detector (PD) angle and transmission range have been observed and analyzed. We have successfully built a prototype of our system and demonstrated maximum photo-detector (PD) angle of 23 degree as well as maximum transmission range of 1.9 meter. This project contributes to further enhance the current LED signaling technology using visible light communications (VLC). The LED not only provides a visual indicator but also act as a communication channel for the vehicles to exchange information as well as providing the acknowledgement for the rear toy vehicles regarding the intention of the front toys vehicles.

The technology of smart or adaptive antenna for mobile communications has received huge interest worldwide in recent years. Using dynamically adaptive beampattern, a smart antenna can eliminate interference signals, increase the system capacity and the spectrum efficiency. Beamforming is the process of forming beams towards the direction of the real user while simultaneously suppressing signals origination from other directions. In this work, interference reduction one of the major problem in wireless communication system, thus, hybrid Particle Swarm Optimization and Gravitational Search Algorithm (PSOGSA) approach is one of the modern hybrid metaheuristic optimization algorithm applied to the smart antenna system. Minimum variance distortionless response (MVDR) integrated with hybrid PSOGSA approach to enhance the MVDR performance by controlling the complex excitation weight coefficients basing linear antenna array radiation pattern synthesis. The performance of the proposed MVDRPSOGSA method is assessed based on various QoS criteria such as beampattern accuracy for azimuth and elevation scanning angles and SINR output. The results reported here have been compared with the results of conventional MVDR technique. It is found that the SINR and output beampattern are in good agreement with MVDRPSOGSA. The proposed approach successfully used to determine the excitation weight coefficients of the linear antenna arrays to produce the shaped-beam patterns and to introduce deep nulls at prescribed unwanted directions. This work proposes a novel method to implement in the wireless communication system to eliminate the multiple access interference source.

This paper provides an introduction about embedded capacitance technology and its implementation on printed circuit board (PCB). The advantages of implementing embedded decoupling capacitance in compact PCB with high speed signal transmission are also explained. The advantages in terms of power and signal integrity are discussed in detail by performing analysis in 2 phases. In phase one, the computation of power distribution network (PDN) impedance of the conventional PCB with discrete decoupling capacitors and the PCB with embedded decoupling capacitance is performed. Meanwhile in phase two, co-analysis of power and signal integrity (PI/SI) on test cases with decoupling conditions mentioned in phase one is conducted to observe the power rail noise and quality of signal transmission. The analysis results are further discussed in the later section of this paper.

Internet of Things (IoTs) concept has opened a window for forest to become a part of the technology connected ecosystem with power under the forest canopy as one of the primary concerns. A multitude of sensors can be deployed under the forest canopy for real time and periodic forest monitoring in the IoTs environment. In this research, the amount of solar power generation under a closed forest canopy is studied in detail. The key objective of this research is to provide an insight on power management for potential IoTs based forest monitoring devices. The minimum, maximum and average solar radiation received under the closed canopy is 1.87W/m^2, 761.67W/m^2 and 74.50W/m^2 respectively. By further computation, the monthly minimum, maximum and average total solar radiation is 10184.24Wh/m^2, 45791.08Wh/m^2 and 21087.47Wh/m^2 respectively. By modeling with a 12V 100W solar panel, the lowest and the highest solar power generated are 0.19W and 76.22W respectively. On the other hand, the monthly maximum and minimum total solar power generated is 4582.22Wh and 1019.12Wh respectively. A typical IoTs environmental sensing Node from Libelium consumes 503Wh per month which is lower than the minimum monthly total solar power generated. In overall, solar power generation is possible under a closed canopy to power an energy efficient IoTs device.

To handle huge data traffic in networks, deployment of femtocell and macrocell in Long Term Evolution (LTE) is the future of the network society. The efficiency of the system is increased. However, the system deployment may yield to major issue such as the inter cell interference with their neighboring cells. The effect of this issue is the occurrence of low quality of service. One of the proposed mitigations is to introduce the new circuitry connections. Other literatures are still going on mitigation techniques which have some positive and negative drawbacks. In this paper, the interference mitigation techniques including reviewing the strengths and weakness are discussed.

This paper presents the development of a three phase linear generator with the output power of 5.4 kW and output voltage of 240 V, with minimum cogging force. Some specific design criteria are employed to meet exclusive requirements related to its stator and translator. A simple model of the electromagnetic analysis of the cogging force and generated E.M.F are presented. Finite element method magnetic (FEMM) software is used to simulate the three phase linear generator. A radial magnetized magnet is chosen to give a high performance characteristic and to solve the cogging force-voltage problem.

Nitrogen (N)-doped zinc oxide (ZnO) nanorod arrays were synthesized on aluminium (Al)-doped ZnO seed layer catalyst using sol-gel immersion method. The XRD analysis showed that the increment in crystallite sizes and lattice parameters while the strain/stress of the films reduced when the concentration increased. The FESEM image revealed that the nanorods exhibit hexagonal shape. The average diameters of nanorods have increased from 150 nm (undoped) to 230 nm (3 at.%). The N-doped ZnO nanorod arrays also displayed good transmittance properties at visible region.
