This paper presents the performance improvement of Helicobacter pylori (H. pylori) infection detection using Kernel Local Fisher Discriminant Analysis (KLFDA)-based decision fusion. As the biggest contribution of this paper, the proposed method extracts more discriminative features based on KLFDA for the decision fusion. Since the decision fusion employed in this paper can consider not only the detection results but also the visual features, by calculating more discriminative features via KLFDA, more accurate decision fusion becomes feasible. Furthermore, experimental results show the effectiveness of the proposed method.
提出了基于核局部Fisher判别分析(Kernel Local Fisher Discriminant Analysis, KLFDA)的决策融合方法，提高了幽门螺杆菌(Helicobacter pylori)感染检测的性能。本文最大的贡献是基于KLFDA提取更多的判别特征进行决策融合。由于本文采用的决策融合不仅考虑检测结果，而且考虑视觉特征，因此通过KLFDA计算更多的判别特征，使得更准确的决策融合成为可能。实验结果表明了该方法的有效性。

This paper presents the coding efficiency impacts using larger intra prediction unit size (PU extension) than HEVC, which is implemented on the HEVC reference software HM-16.4. It is reported that the PU extension up to 128×128 can achieve 0.07 % and 0.19 % on average for normal QPs (QP=22, 27, 32, 37) and high QPs (QP=32, 37, 42, 47) respectively in all intra configuration. The amount of gain by 128×128 Intra PU extension is roughly as half as that of 64×64 Intra PU of 0.18 % and 0.45 % for normal QPs and High QPs. For further study, the number of prediction mode increase, efficient prediction mode signalling and transform size extension should be studied.
本文通过在HEVC参考软件HM-16.4上实现比HEVC更大的帧内预测单元(PU扩展)对编码效率的影响。据报道，在所有intra配置中，正常QPs (QP=22、27、32、37)和高QPs (QP=32、37、42、47)的PU延伸率平均分别达到0.07%和0.19%，最高可达128×128。对于正常qp和高qp, 128×128 Intra PU扩展的增益量大约是64×64 Intra PU的一半，分别为0.18%和0.45%。为了进一步研究，需要研究增加预测模式的数量、有效的预测模式信令和变换大小的扩展。

Recently, portable devices and wearable devices are widely used. The security is the most important problem for these devices. Usually, the confidential information in these devices is protected by encrypting data. These portable devices have area constraint. Therefore, AES, which is the most popular encryption standard, cannot be applied to these devices. Lightweight block ciphers require small area for their implementations. Therefore, lightweight block ciphers are used in portable devices. On the other hands, the threat of hardware Trojan against cipher circuit in electric devices has been pointed out. This study proposes a new hardware Trojan and examines to the characteristic of the proposed hardware Trojan by using a FPGA.

BCI (Brain-computer Interface) has been attracting attention as an interface to connect the brain to external devices. However, it is essential to establish methods to recognize the brain state accurately in order to implement BCI, and a number of challenges still remain. Here, we suggest a novel BCI system that accurately recognizes and isolates emotions like delight, anger, sorrow, and pleasure using an Emotion Fractal Analysis Method (EFAM), which can quantify emotions based on data obtained by electroencephalography, and control an electric wheelchair using the information. With this method, a high average rate of recognizing emotions (delight, anger, sorrow, and pleasure) of 55-60% and markedly high rate of isolating them of over 97% can be achieved. We developed the BCI circuit to control an electric wheelchair based on data on emotions obtained in realtime by EFAM. Using this circuit, the speed of an electric wheelchair can be adjusted by the intensity of emotions.

In this study, we developed an audio system that is made up of speaker system of regular polyhedron enclosure, and multi channel digital audio amplifier. The speaker system has loudspeaker units that are independently wired out of the enclosure, and are controlled independently. The amplifier can control their output timing and amplitudes independently and precisely. With this combination, we aimed to spuriously deform shape of the enclosure. In this demonstration, we show a trial implementation, and hope you to sense the effect, and wish to hear your impressions and advises.

Agent-oriented computing is a technique to run a big-scale system by cooperation among plural agents. An agent with learning ability is called a "Learning Agent". A learning agent learns past actions, and changes the movement knowledge dynamically. A learning agent can solve a complicated problem in intellectual action. However, when a user wants to use a learning agent, little support exists for the development of a learning agent in an agent framework. Therefore, we introduce the development support of learning agent into the DASH agent framework.

In this paper, we propose the power saving method of the intelligent bus stop for demand responsive bus. To save the power of the intelligent bus stop, we use normally off computing to execute its function only when users use it. When we practice a demonstration experiment in Nanae town, the error rate of pyroelectric sensor to detect users is 37 %. The power consumption of communication function to communicate with bus server is the biggest of all functions in it. To save the power consumption, we reduce the communications to the server by improving detection using a camera.

In this paper we propose a novel method to measure the contrast reduction in a digital image, and its application on LCD backlight dimming. The contribution of this paper is twofold. First, we propose a new key concept, burstiness, in measuring the contrast reduction. Second, there has not been a backlight control method that quantifies the image quality degradation in terms of contrast reduction, and optimizes it with power consumption. By considering the spatial distribution characteristic of contrast reduced pixels, the proposed method effectively captures the contrast reduction. This leads to a gain in the power saving in the backlight dimming while visual perception quality is maintained.

This paper proposes "Haconiwa," a toolkit for learning how to build a basic electronic circuit intuitively. The toolkit is intended to motivate participants to develop an interest in electronic circuits. The toolkit aims at fostering the interest of participants in electronic devices and provides users with the pleasure involved in making products. The toolkit consists of two types of modules: basement modules and object modules (e.g., LED, battery, and switch). Users can customize the appearance of the object modules by decorating them with fancywork. By connecting the decorated modules with the basement modules, users can make their own original miniature scenery.
