[en] Loading-unloading system is one of the major systems of the SVST-Co60/B irradiator. However, this system has been operating by hand, it takes a lot of time and health of workers leads to labor-productivity is low. This project aims to design and manufacture a tote box loading system which works fully automatic and an unloading system works by manual of the SVST-Co60/B irradiator in order to reduce physical labor at the loading-unloading area.

[en] This paper develops a computational technique for finding the maximum allowable load of mobile manipulator during a given trajectory. The maximum allowable loads which can be achieved by a mobile manipulator during a given trajectory are limited by the number of factors; probably the dynamic properties of mobile base and mounted manipulator, their actuator limitations and additional constraints applied to resolving the redundancy are the most important factors. To resolve extra D.O.F introduced by the base mobility, additional constraint functions are proposed directly in the task space of mobile manipulator. Finally, in two numerical examples involving a two-link planar manipulator mounted on a differentially driven mobile base, application of the method to determining maximum allowable load is verified. The simulation results demonstrates the maximum allowable load on a desired trajectory has not a unique value and directly depends on the additional constraint functions which applies to resolve the motion redundancy

[en] According to the flux mapping data, some of domestic WH type plants have experienced AOA (Axial Offset Anomaly) in several years. AOA is a phenomenon that the axial power distribution is considerably shifted to the bottom of the core compared with the predicted one. The root-cause is known as the deposition of boron compound (LiBO₂) in the crud that is accumulated in the upper portion of a fuel assembly. At first, by analyzing flux mapping data, we have modeled AOA experienced cycle by 3D depletion code and determined approximately the boron mass deposited in crud. AOA model can be used to evaluate the effects of AOA. In addition, we need to setup a procedure to assess loading patterns for AOA risk and to give recommendations to the operators, if necessary. As a part of Loading Pattern Risk Assessment, we constructed the AOA prediction system to evaluate whether the selected loading pattern has the higher AOA risk or not. This procedure is described herein and application results are presented

[en] We demonstrate the recently developed technique of laser driven isentropic compression (ICE) for dynamically compressing Al samples at high loading rates close to the room temperature isentrope and up to peak stresses above 100GPa. Upon analysis of the unloading profiles from a multi-stepped Al/LiF target a continuous path through Stress-Density space may be calculated. For materials with phase transformations ramp compression techniques reveals the location of equilibrium phase boundaries and provide information on the kinetics of the lattice re-ordering

[en] This paper considers a steady-state crack propagating along an interface between dissimilar orthotropic materials under an asymmetric load. Although most of the known results so far deal with symmetric loading, it has been shown recently that a significant asymmetry in the applied loading may lead to a pronounced effect in terms of the values of the SIFs. The aim of the paper is to extend these results from the static case to a moving crack. In particular, we show the significance of the asymmetry of the loading for computing the energy release rate

[en] A software bus, just like its hardware equivalent, allows for the discovery, installation, configuration, loading, unloading, and run-time replacement of software components, as well as channeling of inter-component communication. Python, a popular open-source programming language, encourages a modular design on software written in it, but it offers little or no component functionality. However, the language and its interpreter provide sufficient hooks to implement a thin, integral layer of component support. This functionality can be presented to the developer in the form of a module, making it very easy to use. This paper describes a Pythonmodule, PyBus, with which the concept of a ''software bus'' can be realized in Python. It demonstrates, within the context of the ATLAS software framework Athena, how PyBus can be used for the installation and (run-time) configuration of software, not necessarily Python modules, from a Python application in a way that is transparent to the end-user

[en] Human osteoarthritic chondrocytes (hOACs) are characterized by their “dedifferentiated” and catabolic phenotype and lack the ability for restoring their inherent functions by themselves. Here we investigated whether extrinsically supplemented mechanical signal via compression loading would affect the phenotype of hOACs. Specifically, we applied cyclic compression loading on cultured hOACs-collagen constructs and measured the expression of the major chondrogenic factors, cell-matrix interaction molecules and matrix degradation enzymes. Dynamic compression loading stimulates the expression and nuclear localization of sox9 in hOACs and reduces the catabolic events via downregulated expression of collagenases. These results contribute to better understanding towards mechanoregulation of hOACs.

[en] Some problems such as misoperation of runaway-proof device, position limit switch damage by weightbox are often encountered in using runaway-proof device in inclined shaft. Aimed at these problems, some technical improvements of the runaway-proof device are made, including improving the accuracy of depth indicator, controlling the moving trace of weightbox, reducing the number of switch from two to one, and so on. Practices prove that the technical improvement of the runaway-proof device in inclined shaft is successful. (authors)
