In this work, we extend WuKong middleware to interface with context engine, to learn the context based on the history of user behaviors, and to command the devices in the system according to the context. With the enhanced WuKong framework, one can design and implement context-ware/user-behavior-aware IoT applications using FBP in WuKong middleware.

This paper proposes a distributed approach for multiple-targets tracking in a visual sensor network. A geometric structure of asymmetric Voronoi diagram is constructed to make the approach be applicable to those visual sensors that sensing distances are different. The objective of the proposed approach is to improve target tracking results of a visual sensor network.

Noise cancellation is very important step for ECG signal processing. For this problem, there are many methods had been applied. For example, Wavelet based de-noises, EMD based de-noise, Kalman based de-noise, etc. for resource very limited system, the above method may be not fit into the system resource. Algorithm complexity and resource requirement will be the major concern in this work. In this paper, a new processing flow is proposed. it is combined two concepts, one is moving average and another is soft-thresholding. First, we will explain the whole process. Next, the performance will be discussed. And at the last, we will talk about the possible way to improvement the flow.

Recommender systems, which recommend products, content, or learning resource to users, have become an important issue and received a lot of study. Existing recommender systems utilize different knowledge source to profile users, but in some application fields, such as retailer, obtaining such source can be different. In this paper, we propose a facial recognition integrated recommender system to deal with the profiling problem at a retail store. Evaluation result shows that this system makes recommendation very well.

Audio Fingerprinting (AFP) is a technology, which requests huge computing power for responsiveness, accuracy, and robustness to noise. In this study, we make efforts to improve the computing speed of fingerprint extraction in AFP system by parallelism language OpenCL. Especially, we also explore the function and speed portability across different platform. The experimental results show that the portability of function is trivial by syntax check and utilizes conservative syntax for different compilers, such as Microsoft Visual Studio and Linux GCC. On the other hand, the speed portability requests much works for optimization of different sub modules for the specified platform.

It is shown that public key cryptosystems based on discrete logarithm probrem can be solved if the quantum computer and Shor's algorithm are realized. Thus a new cryptosystem called post-quantum cryptosystem so as not to be broken by quantum computer is needed. NTRU is proposed by Hoffstein et al. in 1998. It is one of post-quantum cryptosystem. It is based on problems on lattice for which there are no efficient algorithms to solve. In NTRU, using convolution polynomial ring as Zq[X]/(Xn-1). However, (X-1), that is a trivial factor of Xn-1 sometimes make problems. Thus we consider a variant using a quotient polynomial ring such as Zq[X]/(Xn + Xx-1 +...+X + 1) and CVMA: Cyclic Vector Multiplication Algorithm.

A voltage reference circuit providing a mean voltage of 281mV is proposed in this work. All transistors are biased in weak inversion region, and the 0.18um mix signal process is used in the simulation. This design is based on the weighted different threshold voltage between two devices, which has ultra low-power consumption of 1.5nW on 1V at room temperature. Besides, the temperature coefficient of voltage is as low as 16 ppm/°C at best@1V and 40 ppm/°C on average in a range from 0°C to 150 °C. The supply voltage of the proposed voltage circuit is from 0.65 to 5 V, and the power supply rejection ratio (PSRR) is -54dB@100Hz. The active area of circuit is 0.0013 mm2.

In this work, we proposed a new adaptive method for handwriting documents denoising, which differs from others in the two aspects: 1) The proposed method's process is an adaptive histogram equalization to suppress unwanted interfering strokes, and 2) It develops a clear document image by using adaptive directional lifting-based discrete wavelet transform enhancing operations for the foreground and interfering strokes, respectively. As a result, this method not only removes the interfering or visible watermarking in background information but also significantly increases the readability of each document.

A variety of contents sharing methods that are available on Peer-to-Peer networks have been actively researched these days. We proposed a system using not only the peers' storages but also cloud storages for possessing the shared content items, which achieved higher contents acquisition rate and lower network load than conventional systems. However in the research, the situation where the popular content items are generally different among nations or regions was not considered. Therefore this research proposes the efficient contents sharing method taking into account the difference of contents popularities depending on regions, and in addition, evaluates the efficiency of the proposed method by computer simulations.

This paper presents the performance evaluations of GMP-based applications on Web-based Volunteer Computing (VC) systems. Web-based VC is expected to gather many volunteer participants (workers) by allowing workers to execute a computation program (job) on Web browsers. On the other hand, the job execution performance on workers degraded because jobs are executed on Web browsers. To reveal the actual performance of Web-based VC, we convert practical applications which use GMP, that is a multi-precision library for scientific computations, and evaluate its performance. The experimental results show that the performance degradation is negligibly small in some cases, e.g. a short bit-length of arguments. This paper also shows a potential for the performance improvement of Web-based VC by substituting GMP functions.
