The current ultrasound therapy machines are implementing continuous waveform, which in fact, is not an optimum technique for therapy treatment process. Apparently, pulse waveform appearing as a more effectively way of signal generation in terms of its power consumption, low cost hardware and short timing used. In order to overcome these drawbacks of conventional therapy machines, we proposed a programmable pulse generator for pulse waveform production with high frequency more than 1MHz through Cyclone 2 Field Programmable Gate Array (FPGA) development board. The generator is developed with maximum controllable 10 number of burst and clock frequency 50MHz. Register Transfer Level designs with Very-High-Speed Integrated Circuit Hardware Description Language (VHDL) coding are also implemented throughout this project. Pin assignment was used to assign the pin connection in FPGA for linkage of input and output data of FPGA. The result of generated waveforms were observed using oscilloscope. Based on the findings, the developed programmable FPGA is able to produce high frequency signal effectively and accurately.

Conventional Canny edge detector can detect edges in image with additive noise effectively but not ultrasound image that are corrupted by multiplicative speckle noise which alleviates image resolution resulting in inaccurate characterization of object features. In this paper, we proposed to incorporate the modified SRAD into the Canny edge detector to replace the Gaussian blurring in the conventional Canny edge detector in order to suppress the multiplicative noise effectively while preserving the edge of the object in ultrasound image. The result shows that the proposed method can provide better result than conventional method in a much wider range of parameter values. The proposed method through experimental result indicates that it is capable of producing promising edge detection result in ultrasound image.

Ultrasound medical imaging is widely used nowadays in clinical application due to its intuitive, convenient, safety, non-invasive, and low cost. However, ultrasound image formation always comes with speckle-noise which will greatly reduce the image quality, and makes the identification and analysis of image detail become more challenging. Hence, we present an extended robust diffusion algorithm for optimum diffusion while retain the edge of image features. Total eight spreading diffusion directions are implemented in the proposed algorithm. Finding showed that this method is able to provide consistent and more objective results.

Amid the extremely active Semantic Web community and the Social Web's exceptionally rising popularity, experts believe that an amplified fusion between the two webs will give rise to the next huge advancement in Web intelligence. Such advances can particularly be translated into ambient and ubiquitous systems and applications. In this paper, we delve into the recent advances in knowledge representation, semantic web, natural language processing and online social networking data and concepts, to propose an inclusive platform and framework defining ambient recommender and decision support systems that aim at facilitating cross-sectional analysis of the domain of childhood obesity and generating both generic and customized preventive recommendations.

This article proposes an approach that accelerates the realization of user identification schemes that follow the principle of zero knowledge. The proposed approach is based on using finite field arithmetic to replace the usual modular arithmetic approaches. The application of this efficient method that was developed using Galois Fields, renders feasible an exponential reduction of the computation time required for classical zero knowledge authentication methods, such as FFSIS, Schnorr and Guillou & Quisquater. Modifications of the relevant schemes are presented that use Galois Field multiplication operations. It is shown, both theoretically and experimentally that the proposed procedure attains a per order acceleration of the execution time required for the user authentication by 2 - 3 orders of magnitude, via a hardware implementation.

In proteomics 2-dimensional SDS-polyacrylamide gel electrophoresis (2D-PAGE) is the most widely used method for analyzing protein mixtures qualitatively. There are, however, a lot of noise and measurement biases which needs to be accounted for both in the localization of spots as well as in the quantitative measurement of protein expression. Previous techniques for denoising 2D gels are based on thresholding, smoothing and spot recognition. Wavelet transformations have also been applied to denoise 2D gels, however these techniques are typically in the frequency domain and they tend to shift spots slightly. In this paper, we improve the protein spot detection process by wavelet de-noising based on genetic algorithm.

The primary goal of software repositories is to store the source code of software during its development. Developers constantly store small parts (i.e. software modifications) of code into the repository and share those parts with others until the software is finished. However, software repositories store a significant amount of information about software and development processes. With the appropriate tool, source code modifications could be identified. In the article, we will introduce a tool for identifying structural source code changes from software repositories. With this tool, three open source projects were analyzed and different source code changes were identified during their development. We showed that the tool could be used to identify source code changes from software repositories.
