Abstract: There are provided a sample holder that allows in-situ observation of a sample such as a gas or liquid under light irradiation and an electron microscope. An environment cell is formed in combination of two silicon chips, each including a membrane and a frame supporting the membrane, the frame being provided on the opening. The environment cell is accommodated in a main body of the sample holder, and fixed by a lid. The openings of the lid, the two silicon chips, and the main body are placed so as to overlap with each other along the optical axis of an electron beam of an electron microscope. A light emitting element is placed at a position where any one of the openings of the two silicon chips is allowed to be irradiated with light.

Abstract: Aim for early promotion of a circular economy. After the start of use of a product including a plurality of modules, a module to be removed included in the product is replaced with a new module (a module of which a value has improved in a predetermined product value item compared to the module to be removed). Note that the new module is a module completed by article circulation of a module removed from the product or another product.

Abstract: A processing device included in a protocol evaluation support apparatus executes creation processing (S302 and S303) for creating a simultaneous merging symbol at a portion in a protocol where a plurality of elements simultaneously merge into one element, and creating a simultaneous branching symbol at a portion in a protocol where one element simultaneously branches to a plurality of elements, development processing (S304) for developing the protocol for each of paths included in the process procedure, removal processing (S305 and S306) for removing all of the elements that are duplicated in a process after the simultaneous merging symbol and removing all of the elements that are duplicated in a process before the simultaneous branching symbol for the protocol, and calculation processing for making each of individual evaluation values correspond to each of the remaining elements and calculating an overall evaluation value of the protocol based on the individual evaluation values made to correspond to the remaining elements for the protocol.

Abstract: Accuracy and processing speed for searching in searching for a pattern that matches a log is achieved with a log normalization apparatus for normalizing a log output from an information processing system into a structured log. The apparatus has a log input unit that receives a log output from an information processing system; a storage unit that stores pattern information, which are patterns of logs, and a first priority information indicating a first priority for pattern matching corresponding to a log transmission source. A pattern matching unit is configured to, when the log received is a log transmission source corresponding to the first priority information, perform pattern matching between the log and the patterns in the pattern information using a pattern corresponding to the first priority and convert the log into a normalized log using the pattern matched, and the normalized log converted by the pattern matching unit is output.

Abstract: A rail vehicle has a return flow path structure formed by a lower tube portion, an upper tube portion, a seat, and an opening or a notch of a seat base. When air flows from the inside of a vehicle cabin to an exhaust port connected to an exhaust air flow path under a floor via the return flow path structure, a direction of a flow passing between an outer periphery of the lower tube portion and an inner periphery of the upper tube portion is opposite to a direction of a flow passing through an inner side of the lower tube portion.

Abstract: Power demand at each base is adjusted so as to improve a renewable energy utilization ratio at all bases. An inter-base workload control system manages an amount of excess power obtained by subtracting a power supply amount of the renewable energy power supply from a power consumption amount associated with execution of a workload in a future time range at the bases, spatial migratable time range information on a spatial migratable time range where spatial migration of migrating the workload in a future time range at the bases to another base is possible and temporal migratable time range information on temporal migration of delaying execution of the workload in the future time range at the bases within the same base and migrating the workload to another time range and a predicted amount of power consumption through execution of the workload in the future time range at the bases.

Abstract: A power procurement plan creating system or the like that creates a proper power procurement plan is provided. A power procurement plan creating system includes a control unit that causes a display means to display a power procurement plan adopting a combination of supply/procurement sources, the combination being selected based on a given evaluation index, from among a plurality of supply/procurement sources that are power supply sources. The evaluation index includes a degree of stability that indicates a degree of stable supply of power to a demand side. The control unit displays the degree of stability on a display screen for displaying the power procurement plan.

Abstract: An object of the invention is to provide a control technique capable of connecting a storage battery to a DC bus via a DC/DC converter and controlling charging and discharging of the storage battery by the DC/DC converter. A DC grid system according to the invention calculates a voltage command value of a DC bus using a present voltage of a storage battery and a target voltage of the storage battery, and provides the voltage command value as a command value for each of an AC/DC converter and a DC/DC converter (see FIG. 1).
