By large tsunami damage due to the Great East Japan Earthquake, many existing network system stopped functioning in various factors. Even under such circumstances, some of the information communication method that including satellite communications, it was able to recover the Network Connectivity, actually quickly and effectively. Although there are some valid information communicating method in disaster, however the information communication method has a strong and weak points, when using each a single unit, it is not possible to follow the disaster area of the situations to be constantly changing. In addition, the emergency information communication system there may not be available in the battery out and do not know how to use in case of emergency. Therefore, it is important to design a systems available without a disaster by providing enough Network Capability. We develop a Never Die Network (NDN) system that is a new network system to achieve both the Network Capability in the normal and Network Connectivity in disaster based on the experience of Great East Japan Earthquake. In this paper, we propose a method for the system to autonomously derive the optimum packet flow by measuring the communication state such as throughput and packet loss in a system such as to considering multiple different access networks. We prepared a test bed that implements a prototype system, and evaluated based on a disaster scenario.
由于东日本大地震造成的巨大海啸破坏，许多现有的网络系统因各种因素而停止运行。即使在这样的情况下，包括卫星通信在内的一些信息通信方式，也能够迅速有效地恢复网络连接。虽然灾害中有一些有效的信息通信方法，但是信息通信方法各有优缺点，在使用单个单元时，不可能跟随灾区的情况不断变化。此外，应急信息通信系统中也有可能没有可用的电池出来而不知道如何在紧急情况下使用。因此，通过提供足够的网络功能来设计一个没有灾难的可用系统是很重要的。NDN (Never Die Network)系统是在东日本大地震的基础上，为实现正常情况下的网络能力和灾害情况下的网络连通性而开发的一种新型网络系统。本文在考虑多个不同接入网的情况下，提出了一种通过测量系统中吞吐量和丢包等通信状态来自动导出最优包流的方法。我们准备了一个实现原型系统的测试平台，并根据灾难场景进行评估。

Nowadays, most of the information available on the web is in Natural Language. Extracting such knowledge from Natural Language text is an essential work and a very remarkable research topic in the Semantic Web field. The logic programming language Prolog, based on the definite-clause formalism, is a useful tool for implementing a Natural Language Processing (NLP) systems. However, web-based services for NLP have also been developed recently, and they represent an important alternative to be considered. In this paper we present the comparison between two different approaches in NLP, for the automatic creation of an OWL ontology supporting the semantic annotation of text. The first one is a pure Prolog approach, based on grammar and logic analysis rules. The second one is based on Watson Relationship Extraction service of IBM Cloud platform Bluemix. We evaluate the two approaches in terms of performance, the quality of NLP result, OWL completeness and richness.

High Performance Computing infrastructures are getting increasingly heterogeneous, which offers opportunities to the applications in terms of performance improvement. However, the “hardware-concise” heterogeneous resource allocation requires a deep knowledge of the scheduled applications’ characteristics. The challenge is getting more difficult if the scheduler has to balance the optimization policies between the application- and the infrastructure-specific policies, e.g. the overall energy consumption, resource utilization, etc. We introduce a heuristic-based approach to adaptive scheduling, enabled by in-depths monitoring technologies. Our solution is complementary to the native schedulers like Torque or Maui and is open per design and thus can be seamlessly integrated into the core scheduling algorithms.

Hemiplegia is a disease where the sufferer has difficulties moving the muscles, and thus rehabilitation is required. We propose a method for real-time CG animation of the cooperative motion of both hands for a mirror box therapy support system in place of mirror box therapy. This system displays cooperative movement through CG. The image of a healthy hand is displayed in real-time. On the other hand, the image of a hemiplegic hand is substituted by motion capture data of the healthy hand. In this system, patients perceive the hand by replaced motion capture as their affected hand, and the brain is "tricked" into believing that it is. We use a leap motion device for motion capture and obtain the position information of the fingers. We evaluate our system by applying it to six people.

Recently, in cloud computing, the power consumption is one of the most important topics. The power consumption of ARM processor is smaller than popular x86 processors. However, because of no virtualization technology, ARM cannot be applied to cloud computing. ARM is suited for low power cloud, which does not virtualize hardware. However, even if low power cloud, network must be virtualized to provide it as a service on demand. In this paper, we propose mesh based scalable virtual network using OpenFlow. In this network, we employ crossbar switch to connect a node to any other node in mesh. Using crossbar switch, we can organize any group that consists of any number of nodes. The crossbar switch is controlled using OpenFlow. We construct a crossbar switch with Raspberry Pi, ARM single board computer. In this paper, we evaluate the performance of crossbar switch and verify its practicality.

Wireless Mesh Networks (WMNs) are attracting a lot of attention from wireless network researchers, because of their potential use in several fields such as collaborative computing and communications. In this paper, we present the implementation of a testbed for WMNs using Raspbian OS. We analyze the performance of Optimized Link State Routing (OLSR) protocol in an indoor environment considering Transmission Control Protocol (TCP) and Line-of-Sight (LoS) scenario. For evaluation we considered throughput, hop count, delay and jitter metrics. The experimental results show that the nodes in the testbed were communicating smoothly.

For de novo transcriptome analysis, choosing a closest reference model specie in terms of evolutionary distance is a general approach for gene mapping and genome annotations. However, not every selected reference model species possesses comprehensive genome annotations and curated information, and the total number of mapped genes from the selected reference species could not be fully expected either. Due to inefficient mapped genes from the selected reference model species, the following functional pathway analysis on transcriptome datasets would be seriously affected. To solve this problem, we proposed an improved approach based on multiple reference model species selection, especially for KEGG pathway analysis on differentially expressed genes. Applying union operations on individually mapped genes from different selected species, we could significantly promote the integrity of gene mapping results in KEGG pathways and provide realistic P-values for each identified pathway. Furthermore, based on mapped genes and KGML datasets, we applied various gray-levels, colors and shapes to present gene expression conditions on each biological pathway. Taking NGS transcriptomic datasets from an unknown Antarctic green alga species as an experimental example and selecting three published known species including Chlamydomonas reinhardtii, Chlorella variabilis, and Coccomyxa subellipsoidea as candidate reference species, we compared the results of pathway enrichment analysis by adopting different selections of reference species. We found that integrating all mapped genes from various model species provided a better result compared to using any single reference species. Some missed important biological pathways could be retrieved under an identical threshold setting of P-value, such as Ribosome, Pyrimidine metabolism and ABC transporters pathways. Therefore, we believe appropriate selection of multiple reference species is necessary and significant for transcriptome analysis on de novo species.

In this paper, we propose a reliable and interference-aware routing protocol for underwater wireless sensor networks (UWSNs). Proposed protocol follows end-to-end path from source node to sink and selects next forwarder node of a data packet on the basis, having already established a path to sink. In this way, the problem of encounters void hole in depth based routing protocol is eliminated. Furthermore, during the selection of forwarding node, channel interference is also considered as routing metric to provide reliable communication. Therefore, proposed scheme reduces the probability of collision at the network layer, by selecting a neighbor node as the next forwarder of the data packet from the source node to the destination where the chance of channel interference is minimum. Simulation results verify the effectiveness of the proposed scheme in term of energy consumption, end-to-end delay and packet delivery ratio especially in a sparse network.

Over many years, the technology of circuit refinement has achieved a tremendous large-scale integration, so that VLSI systems such as many-core VLSI processor have emerged. However, in the huge VLSI systems, various problems such as many communication problems of the VLSI network, clock synchronization of the entire system, and verification of concurrent processing, must be solved in order to realize a dependable parallel system. In this paper, we introduce a parallel architecture with short path communication, featuring a random connection in Small World Network, and present network architecture without global clock using communicative process by CSP synchronization method.

Against the background of increasing a number of accident in the lanes for cyclists and pedestrians, the authors assumed that these lanes have never been designed from the view point of psychological state of pedestrians. Hence, this paper proposes a design support system that reduces the psychological stress of pedestrians. The major features of our simulator are i) a virtual lane is constructed in a head-mounted display by using a free game engine, Unity, ii) the design conditions of the lane are optimized to reduce the psychological stress of pedestrians. This study firstly constructs the virtual pedestrian model by using multi-agent system, in which the behavior standards of each agent is modeled with obeying the idea of personal space. The psychological stress is estimated by measuring Normalized Pulse Volume (NPV). In this paper, we achieved to replace the components of the virtual city model originally provided by Zenrin Inc. to more realistic components we have developed in this study.
