In this paper, the method of imposing of nulls in the radiation pattern of an antenna array is hashed out using Real coded Genetic Algorithm (RGA). Circular array antennas lying on x-y plane is assumed. The array is assumed to have the maximum radiation along positive z-axis. Single and multiple nulls are imposed by optimizing the current amplitude excitations of each element through RGA. Various simulated results are presented and hence nulling performance is analyzed.

In the paper three most popular methods for spanning the wireless sensor networks (WSN) have been studied with respect to their offered reliability and intra-network radio interference. The authors proposed an algorithm for creating fully planar and reliable WSN structures that, unlike the other algorithms, considerably increase the Signal-To-Noise and Interference (SNIR) ratio in mesh networks, which advantage is particularly emphasized when directional antennas are used. Next, the influence of the number of sink nodes has been studied which ended with conclusion that a properly chosen sink nodes configuration may remarkably extend the network lifetime by bringing the number of necessary hops minimum.

There has been increasing usage of Multiple Description Coding (MDC) for error concealment in non ideal channels. This paper attempts to conceal the error and reconstruct the lost descriptions by combining MDC and LIoyd-max quantizer. At first original image downsampled to four subimages then by using wavelet transform each subimage is mapped to transform domain then descriptions are quantized by LIoyd-max and coded. Since in proposed method wavelet transform is been used, there could be no blocking effect as compared to DCT transform. The results show that average MSE (mean square error) for our proposed method in comparison with DCT method (in other paper) has decreased from 240 to 152 in 0.625 bpp (bit per pixel), from 161 to 107 in 1 bpp and from 96 to 73 in 2 bpp in rate-distortion performance. Therefore, this method is suitable for low capacity channels. By losing descriptions, the obtained image is still in good quality (subjective evaluation and PSNR values) as compared to a method which is DCT and MDSQ (multiple description scalar quantization).

This paper presents performance of Quasi-Cyclic low-density parity-check (QC-LDPC) codes on a flat Rayleigh fading channels by employing DPSK modulation scheme. The BER curves show that large girth and diversity level robust the system performance. Moreover, Prototype architecture of the LDPC codes has been implemented by writing Hardware Description Language (VHDL) code and targeted to a Xilinx Spartan-3E XC3S500E FPGA chip. Simulation results show that the proposed QC-LDPC codes achieve a 0.1dB coding gain over randomly constructed codes and perform 1.3 dB from the Shannon-limit at a BER of 10−6 with a code rate of 0.89 for block length of 1332.

We studied the relationships between the acoustic fluctuation properties of music and the emotional evaluations of music as a component technology for an automated song selecting system based on instinct and human emotion. When people listen to music, they select songs reflect their own feelings at the time, and then they emotionally evaluate the song. We believe that our emotional evaluation of songs are influenced by the fluctuation properties of both the volume and pitch of songs. Thus, we focused on the fluctuation properties containing dynamic ideas concerning music, and extracted thirty six fluctuation properties concerning both the volume and pitch from each song using the Fast Fourier Transform. We also prepared a subjective evaluation experiment for plural songs using the Semantic Differential method, and obtained an emotional evaluation of the songs. Then, we studied the relationships between the extracted properties and the emotional evaluations of the songs by conducting a multiple discriminant analysis. As a result, a high percentage of the questions were answered correctly and low discriminant errors were shown, and therefore, we suggested that the fluctuation properties of the songs influenced the emotional evaluations of them. Furthermore, we confirmed the especial properties related with the emotional evaluation of the music by taking into consideration the coefficients of the liner discriminants of the canonical variates that describe the discriminant spaces.

Electronic Medical Record (EMR) systems are the most innovative information technology infrastructure in the recent decades that facilitate the improvement of healthcare quality, efficiency and safety. EMRs are used by medical practitioners in storing, handling, and consulting the patients' data. Decision support is one of the most useful and promising features of EMRs, which is yet to be fully adopted in healthcare sector. The reason of the uncommon use of the decision support feature is partly due to the complexity of medical processes and protocols, and partly due to the technological constraint. In this research, the re-admission prediction feature was investigated as a part of decision support in EMRs. The emergency re-admission time window was used to design the proposed re-admission prediction feature. This research also examined how the appropriateness of the width of a time window contributes to the design factor of the proposed re-admission prediction feature. This research demonstrated that the use of emergency re-admission time window is appropriate in the design of re-admission prediction feature. The research outcome allows the users of EMRs to manage the re-admission case in hospital.

Operational Amplifiers (op-amps) are one of the most commonly used blocks in analog and mixed signal VLSI design. Designers often spend considerable time in designing op-amps analytically, and then realize that the simulated circuits do not match with analytical expectations. This is primarily due to modeling of short channel MOS devices using long channel equations. Finally an adhoc mechanism is adopted to realize the op-amp with the help of a simulator. Proposed Potential Distribution Method (PDM) is a method where the design methodology is based on actual behavior of the devices and it is free from any analytical expression. This paper demonstrates the design approach for realizing a fully differential folded cascode op-amp using PDM, which is based on simulator results obtained with predefined bias conditions. The dependency of various performance parameters, like slew rate (SR), unity gain bandwidth (UGB), phase margin (PM), etc. on potentials and current distribution at different nodes is presented. It is found that using these dependencies, the target specifications for an op-amp can be achieved with shorter design time. Also, fine tuning the performance metric can be achieved using PDM. Finally, a fully differential folded cascode op-amp is thus designed and the simulation results are presented.

The miR-15/107 group of miRNA gene has been recognized as an important regulatory mechanism for main biochemical pathways in human. It has significant role to play in regulating gene expression that relevant to cardiovascular diseases, cancers and neurodegenerative diseases. Notwithstanding the fact that miRNA has strong implication on human health, an exhaustive taxonomic classification for the miR-15/107 group is impossible because the phylogeny of this group is incomplete. This paper aims at measuring pairwise distances among sequences of the miR-15/107 group of miRNA gene. The distance function allows bioinformaticians to compare the sequence of miR-15/107 group of miRNA gene and predict its target sites.

Multi-view imaging and display systems has taken a divide and conquer approach to 3D sensing and visualization. We aim to make more reliable and robust automatic feature extraction and natural 3D feature construction from 2D features detected on a pair of frontal and profile view face images. We propose several heuristic algorithms to minimize possible errors introduced by prevalent imperfect orthogonal condition and non-coherent luminance trying to address the problems incurred with illumination discrepancies on common surface points in accommodation of multi-views. In our approach, we first extract the 2D features that are visible to both cameras in both views. Then, we estimate the coordinates of the features in the hidden profile view based on the visible features extracted in the two orthogonal views. After that, based on the coordinates of the extracted features, we deform a 3D generic model to perform the desired deformation based modeling. Finally, the face model is texture-mapped by projecting the input 2D images onto the vertices of the face model. As the reconstructed 3D face model is MPEG4 compliant, it can be readily animated by standard MPEG4 facial animation parameters (FAPs). Present study proves the scope of modeling procedure for real-time applications such as face recognition and performance driven facial animation.

The use of wireless sensor network in the smart traffic control systems is very beneficial and starting to be very promising in the design and implementation for such systems. It will help in saving people time and adapt the intersections traffic lights to the traffic loads from each direction. In this paper we present an intelligent traffic signals control system based on a wireless sensor network (WSN). It uses the vehicle queue length during red cycle to perform better control in the next green cycle. The main objective is to minimize the average waiting time that will reduce the queues length and do better traffic management based on the arrivals in each direction. The system also includes an approach to alert the people about the red light crossing to minimize the possibility of accidents due to red light crossing violations. The system was simulated and results are shown in the end of this paper.
