PID control schemes have been widely used for most industrial control systems. However, it is difficult to determine a suitable set of PID gains, because most processes are represented by nonlinear systems. In this presentation, a new PID controller design scheme is introduced for nonlinear systems. This scheme is composed of a cerebellar model articulation controller (CMAC) and a group method of data handling (GMDH).
The common key encryption system is used in the field with a broad system called a block cipher. DES known as a U.S. Government standard code is used as a standard code for a long time. In recent years, standardization of key length's long AES is advanced. In this research, we propose the new common key encryption system based on a geometrical approach. Specifically, the proposed cipher system is a cipher system using the geometric combination of structure information and data arrangement information.
3D shapes of objects can be measured by projecting a light pattern from a projector and capturing an image by a camera. Because the pattern is static and monochrome, the pattern projector can be simple. By using infrared or laser light sources, it can be robust to object textures or environment lights.
SOM is obtained by the learning using a (vector) data including a plural elements corresponding to a subject to determine the type. In this case, it is possible to evaluate objectively out of multiple elements, any element is whether they contribute to the determination of any type are useful in the selection of elements for the production of SOM with high accuracy. The present invention aims for the significance of the data elements of the determination data for that can be determined self-organizing map, and to provide a device for presenting quantitative metrics (or objective) the type and the second type of the first.
In order to establish the sustainable Recycling-based Society and to suppress the petroleum resource exhaustion, the super-engineering plastics, e.g. aromatic polyesters and aromatic poly(ether ketone)s were successfully prepared from furan dicarboxylic acid derived from biomass.
An innovative and rapid removal/immobilization method of heavy metals in polluted soils using nano-size calcium dispersing reagents, under ordinary temperature and pressure, was developed.
This process also achieves simultaneous decontamination of cross-polluted soils with both POPs and radioactive cesium, without the risk of waste-water discharge.
