Abstract: As office workers spend most of their time in front of computer monitors, they are at the risk of suffering from forward head posture syndrome. Repeated head forward postures may cause cervical discs. To address a precautionary approach for the syndrome, we propose a pervasive system. The purpose of this article is to identify design issues in pervasive computing when applied to forward head syndrome, which can give designers insights into how people interacts with the pervasive service and help shape a future research direction to cover those findings.

Abstract: IoT devices are diverse in their characteristics and made by many vendors, hence the inter-operation among them is difficult. Especially, end users can’t make their own programs by do-it-yourselves. IFTTT and Zapier platforms are designed to help end users to make them inter-operable easily and prevail in these days. Their approach is categorized into a Trigger-Action-Programming, in which trigger conditions and actions are already made by professional programmers of several IoT vendors and end users composite them into their own applications easily. But, their drawback is that the composition can be made at once in the first level, hence end …users can’t make more complicated applications. Our approach is based on a dataflow programming paradigm which resembles the TAP in that the internal actions are triggered when all the inputs of a node are prepared. In our approach, a composition of some atomic nodes becomes another atomic node, so the composition would continue iteratively. This feature is so generous that several visual programming languages like LabView are relied on the approach for various fields. We propose the overall architecture of our system and explain them. We also present Internet of Things examples of our approach, which shows that atomic dataflow objects can be associated to produce composite dataflow objects. And they are also composited to make more complex applications iteratively. We compare IFTTT, Zapier, and our approach qualitatively and show that end users can make more diverse and flexible applications in our approach. Show more

Abstract: With the emergence of mobile and pervasive computing, digital gadgets and products have become a pervasive and of our lives. Everyday, they influence us explicitly or implicitly and are changing our way of life as well as our behaviors, either intentionally or unintentionally. Throughout the past decade, research has been conducted to make persuasion interactive rather than unilateral. The outcome is known today as persuasive computing technology. There have been considerable efforts to apply persuasive technology in many domains, especially healthcare. Although these efforts to are gradually coming to fruition, several problems and challenges remain. Most currently available persuasive systems …were not based on explicit theoretical foundations of persuasion theories and models when they were developed. There are two major reasons: (1) a general lack of theoretical frameworks and practical methodologies for building persuasive systems or applications, and (2) it is difficult for computer scientists and developers to understand and harness persuasion theories and models. In response, we have developed an Action-based Behavior Model (ABM) that can be utilized by computer scientists and developers. In this paper, we validate ABM through a scenario-based case, describing how it can be utilized in participatory telehealth to enable persuasion. Show more

Abstract: This paper presents a novel binary classifier based on two best fitting hyperellipsoids in the feature space, called twin-hyperellipsoidal support vector machine (TESVM). The idea of TESVM is inspired by the minimum volume covering ellipsoid together with twin-hypersphere support vector machine (THSVM) which is a variant of the well-known support vector data description (SVDD). Following the concept of THSVM, TESVM constructs two hyperellipsoids where each hyperellipsoid is closest to one class but also as far as possible from the other class in order to form a decision boundary. The construction of hyperellipsoids in the feature space is also enabled through …the use of empirical feature mapping. The experimental results on several artificial as well as standard real-world datasets are provided to demonstrate the performance of TESVM. Particularly, TESVM outperforms its spherical counterpart in term of classification accuracy. Show more

Abstract: As the mobile communication evolves toward next generation, the 5th G, it was required that the number of base stations should be increased and the size of the base station should be reduced. In order for the base station to be designed in small size, we need to minimize the filters in the base station. There are couple of ways to reduce the size of the filters in the base station, one of which is to change the materials for the resonators of filter from the metal to ceramic. The ceramic resonator makes it possible to reduce the size of …the filter at the same time it would be difficult to get the performance as the metal resonator. In order to use ceramic resonator with the same characteristics as the metal resonator, we have to consider the sintering and the fabrication condition of ceramic resonator. This paper introduces the sintering and fabrication condition of ceramic resonator for the filter miniaturization. Show more

Abstract: We present a new approach for generating thumbnail images from H.264/AVC coded bit streams. We have verified analytically that mismatch errors between the encoder and decoder prevent the direct generation of thumbnail images from H.264/AVC transform coefficients. Based on this analysis, we have devised a method that exploits both the spatial and transform domains. What distinguishes our algorithm from previous works is that it determines the thumbnail image pixels by summing the residual and estimate block averages. The residual block averages are directly acquired in the transform domain and the estimate block averages are calculated in the spatial domain. The …proposed method produces thumbnail images that are indistinguishable to the ones produced by the method that decodes the H.264/AVC-I slice bit streams and then scales them down, while, for most of images, it executes almost 3 times faster than the down-scaling method at frequently used bandwidths.

Abstract: Personal content creation has become a significant part of the media industry, and sales are not necessarily the main objective of such creators. Individual creators have a greater need for privacy protection; therefore, the novel active content (AC) approach is proposed to address this need. The Intention Markup Language (InML) markup language is also introduced to express the content owner’s intentions systematically and precisely, and then to implement these as an executable code. To overcome the incompatibility and inconvenience of the existing digital rights management (DRM) systems, the novel AC format is proposed. This is based on the Portable Executable …(PE) format and consists of a PE header and sections, followed by an AC header, the content, and the intention code. The proposed content virtualization technique protects the content against a variety of attacks by treating content in main memory as if it were stored on the user’s storage. Since external players, beyond the AC control boundary, may potentially expose the content, these are controlled by hooking code included in the intention engine while the AC is in use. Finally, example use cases are presented to show how intentions can be expressed in InML documents and the creation and use of an AC file on Windows is demonstrated. Show more

Abstract: A distance estimation method for hopping-frequency-coding (HFC)-based continuous wave (CW) is proposed herein. It is important to frequently update the distance estimate of a near-field underwater vehicle, robust to the time delay, Doppler effect, and volume reverberation. Frequency hopping ensures a high estimation accuracy of the wideband signal without being influenced by the Doppler effect, and also allows the receiver to update the target information at each frequency-hopping instance. The proposed algorithm, which is the initial algorithm for HFC-based CW, focuses on the update period of the estimates and real-time implementation rather than the optimization of estimation accuracy. To achieve …this goal, the proposed method exploits multiple Doppler correlators, a difference moving average filter, and four thresholds. The update period is inversely related to the hopping frequency, which is directly proportional to the Doppler frequency. As the target or transceiver moves at a high speed, the frequency-hopping period can be reduced, and the proposed algorithm can update the target information more frequently. Show more

Abstract: In the system security technology, the information hiding field is developed as technologies for embedding information into digital content as media. The proposed technique is a technical steganography technique which uses a technique of information hiding through physical / statistical change of signal of contents. In the digital watermarking or steganography technology, the embedding process is frequently performed in the frequency domain in order to increase the latent capacity and to improve the image quality. However, these methods have a disadvantage that the computation complexity is high and the constraint condition becomes complicated. In the contrast, there have been various …studies based on histogram shifting technology in reversible information hiding. Assume it selects multiple peaks on the histogram shifting, the capacity of data concealment gradually increased by applying multiple peak histogram method. The steganography technique using histogram shifting doesn’t show any significant improvement for the hiding capacity and image quality in the early methods. In this paper, we analyze the effect of information hiding technology in terms of adopting the histogram shift method including skipping. In addition, we propose 2n divergence data hiding as a complimentary technique to improve hiding capacity. The proposed method has been proven through an example using mathematical expressions, and further improvement measures could be derived. Show more
