The growing amount of data and advances in science have created a need for new kind cloud platform that provides users with flexibility, strong security, the ability to couple supercomputers edge devices through high-performance networks. We built such nation-wide platform, called "mdx" meet this need. mdx platform's virtualization service, jointly operated by 9 national universities 2 research institutes Japan, launched 2021, more features are development. Currently is used researchers wide...

Abstract Local mechanical responses near single grain boundaries (GBs) of 9.8 mol% Y 2 O 3 ‐stabilized ZrO bicrystals, SrTiO bicrystal, and Al polycrystal were investigated by nanoindentation at room temperature to reveal GB contributions the properties. Contrary concept Hall–Petch strengthening, hardness showed negligible variations among interiors, vicinities, just on GBs in samples. Importantly, may be underestimated owing grooving thermally etched Despite change intrinsic hardness,...

This research is based on the questionnaire survey of residents in remodeled detached houses that were built after 1981. Analyzing satisfaction and implementation details terms two aspects – different cost ranges remodeling, whether remodeling projects had been carried out with / without enhanced thermal insulation we found following points.

We propose a high-speed packet forwarding architecture on general-purpose servers, in which Network Interface Card (NIC) drives by direct transfer to other NICs via PCIe switch. The demand for technology servers is increasing with the spread of networking concepts such as Function Virtualization (NFV). However, current architecture, processes packets CPU, cannot achieve similar degree performance that hardware routers can provide because processing capacity CPU and bandwidth main memory...
