Dedicated Short-Range Communication (DSRC) technology is developed for use in vehicle-to-vehicle (V2V) and vehicle-to-roadside/infrastructure (V2I) communications. It uses Orthogonal Frequency Division Multiplexing (OFDM) as constrained by IEEE 802.11p standard. In this standard, the OFDM uses 64 sub-carriers. This paper presents the design on Field Programmable Gate Array (FPGA) Xilinx Spartan-3E of the Transmitter and Receiver Baseband OFDM Section Models for the IEEE 802.11p Stan-dard. Design is carried out using Very High speed integrated circuit hardware Description Language (VHDL). The circuits for both the Inverse Fast Fourier Transform (IFFT) and FFT processing blocks are fully combinatorial, not sequential. The results show that the resource utilization for the 64 subcarriers is more than 100 % and thus can't be realized. Therefore a smaller model with eight sub-carriers is also designed, and it is realizable (implementable).

This paper presents a new computation method for determining critical clearing time (CCT) on the transient stability of power system. The critical trajectory is used as the boundary of stability in the CCT determination. This method also uses a modified trapezoidal equation for numerical integration process. Addition feature, simultaneous equations in the Jacobi's matrix will reduce the equation, so that the number of equations equal to the number of variables. This technique will reduce the simulation time for numerical integration process. The results show that the calculation time of proposed method is faster than the previous method. Therefore it is potentially for on line transient stability assessment.

This experimental study represents a novel technique to increase the overall efficiency of a solar power plant by introducing combine cycle which utilizes the concentrated sun rays in terms of heat to produce additional electricity. For this study a miniaturized solar power station has been designed and implemented which consists of six solar panels with individual sun tracking system. Arduino Uno; a microcontroller board based on Atmega328P; had been used to design solar tracker in order to track the position of the sun for getting the maximum direct sunlight on the solar panels. Three microcontrollers have been programmed to control all six solar panels which were established in a circular shape around a combine cycle system with a mirror on the top which helps to reflect the concentrated sun light to the water reservoir. With the concentrated solar heat reflected from the panels as well as the mirror, the combine cycle heats up the diethyl ether which evaporated only at 34.6°C that flows through a turbine and generate electricity in a generator associated with the turbine. It is observed from this research work that the efficiency achieved from the solar panel with sun tracking device is higher than the usual condition. This overall system increases efficiency of solar station by 8.48% in terms of solar tracker and generating electrical power by the use of concentrated solar heat. The designed miniature model could be helpful to produce more electricity at same place combining solar panel system and combine engine.

In order to improve numerical performance of grounding computation of horizontal multilayer earths, a new type of complex image method has been presented. A closed form expression of Green's function with arbitrary soil parameters, source/observation position has been derived. The infinite value of coefficients A/B in Green's function has been obtained by derived closed form expression. Though numerical value of A/B can be obtained by symbolic algorithms, GNU multiple precision algorithms provides a more simple and reliable way to solve the linear equations of A/B. Then, multi-resolution complex image (MRCIM) method was presented for improvement on both stability and accuracy in numerical grounding computation of horizontal multilayer soils. MRCIM consists of adaptive sampling, decomposition of sampling space, and automations of complex image method approximation. The formula of numerical error by MRCIM has been derived. The validity of MRCIM has been proved by comparative cases. Numerical results show that, during the earth surface potential (ESP) calculation for HVDC transmission earth-return current, DC grounding electrodes can be treated as a current point when observation point is away from over 10 times of dimension of electrodes.

This paper presents a very high speed FPGA implementation of UDP/IP stack. It not only can be a solution to FPGA-external world communication, but also can be regarded as a network node. The physical layer and its interface to the FPGA's IO Blocks are pre-implemented off-the-shelf using an integrated gigabit Ethernet transceiver (Marvell 88E1111) which supports BASE-T standard. The link layer is based on Xilinx Tri-Mode Ethernet MAC core. A novel architecture of transport and network layers by means of both fabric and dedicated FPGA blocks is also proposed which can provide a PC-FPGA and vice versa gigabit data communication. A software program which sends and receives data in connected PC is also developed in MATLAB using DSP System Toolbox. Compared to previous works, the proposed system shows a noticeable speed-up, suitable for FPGA based data streaming applications. Both post place and route simulation and practical tests corroborate validity of the proposed system.

Fingerprint information in a database is very important for indoor localization. A good database can provide good estimation results. Meanwhile, the difficult of providing a good database is the complexity of information recording process. The estimated location of the target can be obtained using the fingerprint information in the database and the observed information. In this paper, the reorganization of fingerprint information in the database is considered. Since the process of recording is complex and time consuming, the solution of this problem is using intersection technique. This technique creates a new information instead of fingerprint information in real recording process. The results shows that the proposed technique has better location estimation compared with the old database since the average error distance is less than the gap between tags (fingerprint locations).

This paper presents the performance of grid-connected inverter when installed in three-phase four-wire distribution system. The inverter is utilized as power converter to inject power. Furthermore, this inverter is also utilized as a shunt active power filter to compensate current unbalance, load current harmonics, and load reactive power demand. It is controlled such a way therefore it draws or supplies fundamental active power from and to grid. The control mechanism is carried out by power balance theory using PI controller. The control system consists of DC voltage regulator, phase-locked loop (PLL), and hysteresis current controller. PI controller is used as DC voltage regulator, which regulates DC-link capacitor voltage to be constant. The performance of this controller is demonstrated through simulation. The results of the simulation show the capability of an inverter to inject power to grid. Particularly for nonlinear load, the current harmonics are compensated effectively.

Closed-loop spatial audio coding is a compression technique, developed based on MPEG Surround (MPS) standard, having an advantage of minimising distortion due to quantisation process of spatial parameters. Despite the MPS is developed based on filterbank, however, this closed-loop system performs better on Modified Discrete Cosine Transform (MDCT). Considering its high performance over the open-loop system, this paper presents further investigation on objective performance of closed-loop spatial audio coding against various quantisers of spatial parameters. Experiments have been conducted to measure signal to noise ratio (SNR) across different types of uniform spatial quantisers at various operating bitrates. The results show that the SNR achieved by the open-loop approach is strongly affected by the type of the quantiser while, in contrast, the SNR achieved by the closed-loop approach is relatively constant regardless the number of bits used in the quantisers. Moreover, the results also show that the closed-loop configuration can consistently improve SNR in any quantisation scheme.

This paper proposes new Simplified Firefly Algorithm (SFA) with an updated β coefficient to maximum power point tracking (MPPT) of photovoltaic system under partial shading condition. The different from standard firefly algorithm is neglected a and y coefficients to simplify an algorithm. The other new feature is updated β coefficient for each iteration step in order to achieve faster convergence. This proposed algorithm is to obtain the optimal solution for MPPT of PV system under three shaded conditions. The simulation results are compared with traditional Perturbation and Observation (P&O) and standard Firefly Algorithm (FA) to verify the proposed method performance. Highest maximum powers and efficiencies are produced by the proposed algorithm. The ripple in steady state condition is also better than P&O and standard FA. The main advantage of proposed algorithm is simpler and faster convergence yet still accurate compared to standard firefly.
