  • Publication number: 20210097459
    Abstract: A worker assignment system reflects the development of the assignment of workers and has a calculation unit which calculates a deficient capability number, which is a number of capabilities lacking in the organization at a given time in the future, from first data including information indicating a number of capabilities required for tasks previously performed by the organization and a number of capabilities of workers of the organization. An identification unit identifies a task and a worker suitable for acquiring capabilities of a maximum deficient capability number calculated by the calculation unit based on second data including information indicating a relationship between the capabilities required for the task to be performed by the organization and the capabilities of the workers of the organization. An assignment unit assigns remaining workers of the organization to remaining tasks to be performed and a result of the assignment is output.

  • Patent number: 8895997
    Abstract: A plurality of electrodes, and carbon nanotubes disposed between the electrodes, at least part of the carbon nanotubes including a metal carbon nanotube are provided. The metal carbon nanotube generates heat upon passing of current to the electrodes and emits light by blackbody radiation, so that the emitted light has a wide emission wavelength region and can be modulated at high speed. This makes it possible to implement a continuum spectrum light source that can be modulated at high speed, which is suitable for use in information communication, electrical and electronic fields.

  • Publication number: 20100262281
    Abstract: To obtain a high accuracy marketing analysis result, while reducing an effect of a low accuracy visual line detection processing, a storage unit of a visual line analysis apparatus stores therein, for each commodity, a basic zone including the commodity and an extended zone at least a portion of which, is overlapped with the basic zone. The basic zone and the extended zone are stored in association with each other. An attention degree calculation part of the visual line analysis apparatus compares positional information on a visual line data detected by the visual line detection part and positional information on each zone defined in a zone definition data to calculate an attention degree for each zone, aggregates attention degrees in each zone for each commodity corresponding to the each zone, calculates an attention degree data for each commodity, and stores the calculated data in the storage unit.
