In the field of nuclear engineering, national colleges have been carrying out important roles with about 10 % of graduates obtaining jobs in nuclear related companies. Although national colleges do not have special courses and classes for nuclear engineering, we have been trying to educate our students in cooperation with universities and industries through the activities of the Japan Nuclear Human Resource Development Network. With aide from the Ministry of Education, Culture, Sports, Science and Technology, we have been developing a short term curriculum for nuclear education consisting of lectures, experiments and facility tours. Moreover, we have developed a textbook for nuclear engineering basics and texts for experiments. In order to let the students understand the background of radiation, radiation dose measurements have been conducted by the students of more than 33 colleges. In the fiscal year of 2015, a new trial of remote lecture connecting 51 national colleges began. Through these education programs, we aim to help our students to understand radiation and nuclear engineering correctly, and to have their own opinions on this important matter.

Most existing mobility management deployments such as MIPv6, PMIPv6 and 3GPP utilize centralized mobility anchors in the hierarchical network architecture. Centralized mobility schemes are subject to restrictions on reliability of SPOF (Single Point Of Failure) and network scalability, etc. As an alternative to the centralized approaches, DMM (Distributed Mobility Management) mechanisms have been actively and widely studied these days. In DMM, functions of the anchor node are efficiently distributed to access routers. This paper suggests the network-based partially distributed mobility management mechanism and performs extensive simulations under various traffic environments for verification and evaluation of the suggested scheme. Performance indexes such as Tx/Rx UDP traffic, end-to-end data transfer delay, binding delay, CPU utilization, WLAN throughput are analyzed and compared among MIPv6, PMIPv6 and the suggested DMM scheme. Simulation results show that the DMM scheme suggested in this paper is useful for IP mobility management research in wireless environment. © 2014 SERSC.

This paper deals with a new practical approach to continuous-time parametric identification for dynamic models in Hammerstein form and its application in the context of estimating the dynamics of joint stiffness. The proposed methodology deals the static non-linearities as a linear combination of nonlinear basis functions, while the linear dynamic parts of the system are modeled by a parametric rational transfer function. The proposed identification method is enabled by the algebra of Volterra linear integral operators by a suitable design of kernels admitting finite-dimensional and internally stable state-space realizations. Simulation results show the effectiveness of the proposed continuous-time identification technique.

As the better high quality image is required for digital image scaling, longer processing time is required so the technology that can make the high quality image quickly is needed. We propose the double linear-cubic convolution interpolation creating the high quality image with low complexity. When compared to peak signal-to-noise ratio(PSNR) and computation time, the proposed interpolation provided better PSNR and low complexity than bicubic convolution interpolation. Copyright 2014 ACM.

In this paper, the real-time attitude determination based Matlab using low-cost receivers was designed and evaluated. The GNSS attitude determination system was implemented to operation in real-time by TimerCailback in MATLAB. The TTM(Transniission Time Misalignment) of U-blox receiver was confirmed through zero baseline tests and this problem was revised, The computed attitude by the high-cost NovAtel receiver was compared to the computed attitude by the low-cost U-blox receiver. As a result of this, the performance of attitude determination systems by low-cost receiver was confirmed. To determine baseline, LAMBDA and BC-LAMBDA for integer ambiguities search methods were used. To confirm suitable integer ambiguity search method in real-time attitude determination algorithm, determined baselines by two methods were compared, and it was confirmed that BC-LAMBDA is more suitable. As a result of this, the operation of real-time attitude determination system was confirmed using 3 low-cost receivers.

With the polynomial vector space decomposition by using Normal Form theory, the normalized analytical solutions of modal resonance are derived, which solves that the traditional Normal Form solution cannot be easily obtained under resonant condition. Based on the solution, from the viewpoint of whether the modal interaction couples and resonates or not, the nonlinear terms are decomposed into four types, i.e., uncoupled nonresonant terms, coupled nonresonant terms, uncoupled resonant terms and coupled resonant terms. The corresponding modes are categorized into 5 types, i.e., single modes, uncoupled nonresonant modes, coupled nonresonant modes, uncoupled resonant modes and coupled resonant modes. A reduced-order mode reconstruction based on least square method to estimate the coefficients of higher-order interactional modes is proposed. This might be potentially a new approach to cope with the challenge from huge amount of higher-order modes in higher-order nonlinear analysis. Two case studies are presented to analyze the types and reconstructions of the nonlinear modes, 2nd- and 3rd- order terms, which verifies the effectiveness of the proposed approach.

The ZigBee communication method, which is the most frequently applied to the LED lighting control system, has drawbacks of low-speed and low-capacity, and the communication failure possibility due to environmental influences is on the rise. Therefore, it is important to secure the communication reliability by applying an integrated interface with a wire-wireless dual-network. This paper developed a communication module, which has a platform converging and combining the ZigBee of USN environments with the PLC of power line communication environments, to implement a dualized communication interface system supporting the wire-wireless integrated protocol, and implemented a wire-wireless networking device and a control system software technology. As a result, it was automatically switched into the PLC communication within 4.4 seconds on average when there was an access failure in the ZigBee communication network, so a reliable communication network was built.

In the paper, we propose a navigation method using fuzzy line tracking and D∗Lite algorithm based on a QR code map. Path planning using D∗Lite is implemented on the server. Fuzzy line tracking is developed by using image processing technique. At first, we design a virtual map which is composed of QR code nodes. We generate an optimized path for navigation on the map. Accuracy of the navigation is enhanced by fuzzy line tracking method. The proposed method is verified by simulation study as well as experiment on a real environment. © 2014 IEEE.

In the present paper, a hybrid architecture based on multi-agent systems is proposed, where it is included a module for formal evaluation. This module, allows the processes verification involved in the level/layer/environment steps. It is also developed a methodology for trajectory tracking based on the generation of a reliable virtual space, on which the navigation takes place under operative conditions (safety and effectiveness). Time processing operations reduction is expected during the inspection.

The problem of adaptively tracking a pre-planned trajectory and rejecting multi-sinusoidal input disturbances with unknown amplitudes, phases and frequencies is addressed and solved for fully-actuated uncertain mechanical systems. We consider the case of disturbances occurring in joint space (adding up with the control torques) as well as the case of cartesian disturbances acting from the external environment. Largely inspired by the work of Chen and Huang [1] on the attitude dynamics of the rigid body, the proposed controller consists of an adaptive internal model unit which estimates in a joint fashion the mismatches in the disturbance frequencies and in the physical parameters. This work is very relevant, e.g., for mechanical systems with flexible appendages where vibrations arising from the flexibility are suppressed by being modeled as exogenous unknown sinusoidal disturbances.
