Abstract:
A system for managing sameAs relationships between ontology instances comprises a sameAs relationship managing unit that checks, sets, or cancels sameAs relationships between ontology instances; a sameAs group knowledge processing unit that receives an input for setting or canceling sameAs relationships from the sameAs relationship managing unit and then corrects related knowledge within ontology instance data; and a sameAs inference service providing unit that uses the knowledge corrected by the sameAs group knowledge processing unit, processes a user query, and performs sameAs post-processing so as to present the result.

Abstract:
A trailing arm mounting structure is provided, in which rear wheels follow a path approximating a straight line, which forms a predetermined acute angle with the road surface to the rear of the vehicle, during bump and rebound of the vehicle body such that shock in forward and rear directions transmitted from the road is reduced and space provided for the backseat and fuel tank is increased. In the trailing arm mounting structure, a first end of a trailing arm is connected to a rear wheel and a second end of the trailing arm is connected to a vehicle body with a concoid curve-forming assembly interposed therebetween.
Abstract:
A device and method for measuring a difference frequency having a simple structure and utilizing optogalvanic effect for measuring a difference frequency when carbon dioxide laser light of a single wavelength is varied in frequency by a measuring object. When a part of frequency varied laser light is mixed with an original frequency of laser light by self-mixing in a laser resonator, a strength of the laser light in the resonator is modulated to a difference frequency between the original frequency and the variation frequency. Since a current change in response to strength of light is generated by the optogalvanic effect in the laser resonator, when a frequency of optogalvanic current change is measured, the difference frequency can be measured.
