In order to find an optimal solution of a research problem, the problem parameters are encoded in discrete space (e.g. bits or integers). Genetic algorithm (GA) performs the discrete space by binary chromosome. Particle swarm optimization (PSO) uses probability and sigmoid function to convert the next bird's velocity into binary bit. Flower pollination algorithm (FPA) is quite new and also has a few number of the paper implements to discrete space. this research uses a cut-off parameter applied on FPA. the main objective is to examine the performance of the algorithms on discrete space and calculate velocity of PSO as well as Levy fight movement of FPA when using discrete parameter. the experiment used eight-numerical functions to test conversion from a real value to a bit value and measure the effectiveness of each algorithm. Experiment result showed that FPA could perform better than PSO and GA.

In the field of embedded system there exists a tradeoff between power/performance optimization, hence many heuristics and techniques were presented at various development levels such as hardware software co-design, schedulers and optimal code compilation. this paper presents an enhanced version of LEON3 architecture which includes support for run-time management of supply voltage and processor operating frequency. this enhancement can be useful to implement various DVFS driving algorithms in LEON3 architecture aiming to leverage power consumption and throughput. Frequency scaling on the fly is based on dynamically reconfigurable clock synthesis feature available in Xilinx FPGA Virtex-4 or higher. the implementation of DVFS in LEON3 architecture is driven and controlled by general-purpose I/O port attached to advanced peripheral bus (APB) to change processor frequency on the fly during the execution of application programs. the work is implemented as a prototype on a Xilinx FPGA platform and incurs very small hardware overheads.

In general, meteor trail interference of owe density (MTIOD) can degrade target detection performance of over-thehorizon radar (OthR). By exploiting MTIOD suppression algorithm based on dyadic wavelet transform (DWT), window function (WF) and CANDECOMP/PARAFAC (CP) decomposition, an effective approach is proposed to solve the problem. the position of MTIOD is calculated through utilizing DWT and WF. therefore, with the data involved in the position, Hankel tensor of three orders is constituted. CP algorithm is applied to resolve the obtained Hankel tensor so as to attain the parameters of MTIOD. On the basis of these parameters, echo signal of MTIOD in time domain is generated. After excising MTIOD from echo data, echo signal without MTIOD is achieved. Compared with the existing MTIOD suppression methods, experimental results have demonstrated the effectiveness of the proposed method which not just improves computational accuracy of the position of MTIOD, but decreases remnant of MTIOD after interference suppression.

Relaxation and calmness are two emotions that people continually seek. One popular method people frequently use to reduce their tension and pressure levels is listening to various types of relaxing music. However, the Quran is composed of Allah's words, which were ultimately given for the benefit of humanity. Muslims strongly believe that listening to or reading the Quran brings them comfort, pleasure and confidence that would otherwise elude them, however, scientific evidence is still required to prove that this belief has a scientific basis. Recently, researchers have used electrophysiology to explore the relationships between electrical phenomena and body processes. this research aims to study and analyse the electrical activity of people's brains and hearts when listening to Quranic recitation compared with listening to relaxing music. Two types of electrophysiology readings are used in this research: electroencephalograms (EEGs) and electrocardiograms (ECGs). An EEG measures brain electrical activity, and an ECG measures heart electrical activity. EEG and ECG data were collected from twenty-five subjects. then, machine learning algorithms were applied to the EEG and ECG signals. the result showed that Quranic recitation demonstrated a positive transformation of the subjects' emotions: from negative precursor emotions to calmness and happiness conditions denoted by a positive valence for the EEG and ECG signals. In contrast, relaxing music showed a positive transformation with regard to the valence in the EEG analysis, however, with respect to the ECG music data analysis, the results revealed a negative transformation for most of the music tracks.

this paper presents the application program of fingerprint detection using wavelet transform for authentication. Fingerprints are obtained from the site of crime, old documents and excavated things. this paper proposes a fingerprint recognition technique based on wavelet-based texture pattern recognition method. By collecting incomplete fingerprints of 2 people with 6 images each. the original seven of uncompleted fingerprint images were undetected and only one was detected. After enhancing image quality using wavelet transform method, it was found that those of seven images were completed. the comparison method was a matching technique. this work focuses on the ability of the program and knowledge of image processing by studying algorithms of image processing. In design algorithm process, different technique enhancements were employed as well as the study of different of filters and algorithms based on existing research results from literature.

In this paper we evaluate a non-blind watermarking technique for colored digital image based on singular value decomposition (SVD) in the DWT (discrete Wavelet Transformation) domain under different PSO variants. PSO is incorporated in the scheme to identify the most suited single value scaling factor to achieve high robustness and similarity ratio, existing PSO variants are compared and the best variant is then applied on the scheme. Experimental results are provided along with statistical analysis to exemplify that proposed scheme using best PSO variant is able to absorb various image processing attacks to a great extent and provide copyright protection.

We consider the initial boundary value problem for the homogeneous heat equation, with homogeneous Dirichlet boundary conditions. By the maximum principle the solution is nonnegative for positive time if the initial data are nonnegative. We complement in a number of ways earlier studies of the possible extension of this fact to spatially semidiscrete and fully discrete piecewise linear finite element discretizations, based on the standard Galerkin method, the lumped mass method, and the finite volume element method. We also provide numerical examples that illustrate our findings.

the main requirements of efficient steganographic systems are transparency, robustness and security. In this work, the proposed system is designed to achieve these requirements, as follows: to increase the transparency and robustness, the proposed system uses the transform domain technique, in this case the wavelet domain technique to embed the color secret image into the color cover image. To achieve high security, chaotic systems are used to accomplish the following two purposes: firstly to scramble the secret color image before hiding it into the color cover image, secondly to randomly select the embedding positions in the cover image. three chaotic systems with many combinations are used for the scrambling and the embedding process. Experimental results including Mean Square Error (MSE), Peak Signal to Noise Ratio (PSNR), Correlation, Signal to Noise Ratio (SNR) and embedding capacity demonstrate that the proposed system has good performance as compared with other existing methods without attack and under different types of attacks such as filtering and noise attacks. Simulation results show that the combination of chaotic systems providing the best performance include the use of Logistic and Hénon maps for the embedding process and Arnold's cat map for the encryption process. the MSE, PSNR, correlation, SNR and embedding capacity obtained in this case reach up to 0.0010, 78.1dB, 0.9999, 67.2dB and 0.39% respectively when the secret image is Airplane with 32×32 pixels and the cover image is Girl with 512×512 pixels. For the extracted secret image, the chaotic system set that provides the best performance includes the use of Arnold's cat map for the encryption process. the MSE, PSNR, correlation and SNR obtained in this case reach up to 0.0846, 58.9dB, 1 and 56.1dB respectively. As compared with other methods, the proposed method achieves gains without any attack of 8.2dB for the stego image and 32.4dB for the extracted secret image in PSNR when the secret image
