Abstract: A sensor device allocation apparatus that allocates a sensor device to an IoT service of the present invention includes a scoring unit that performs ranking of sensor devices satisfying a service requirement by an evaluation function based on specification conditions of the sensor devices and a scheduling unit that determines a control law of the sensor devices ranked by the scoring unit, in which the scheduling unit determines whether a service is satisfied based on collected data of the sensor device collected based on the control law, and the scoring unit corrects the evaluation function and repeats ranking of the sensor devices when the scheduling unit determines that the service is not satisfied.

Abstract: A method of assessing a probe by measuring a known sample whose shape is known with the probe in an electronic microscope, the known sample having a projection part on a surface thereof, and the projection part having a shape tapered toward a vertex thereof, the method comprising a step of measuring circle equivalent radius of the projection part, a step of comparing the circle equivalent radius with a first threshold value, and a step of determining that the probe is satisfactory when the width is less than the first threshold value, and a step of determining that the probe is unsatisfactory when the width is equal to or greater than the first threshold value.

Abstract: A nonflammable olefin thermoplastic elastomer composition (F) for use in skins of interior automotive trim, which comprises an oil-extended olefin thermoplastic elastomer composition (G), melamine-coated ammonium polyphosphate (h), a specified 1,3,5-triazine derivative, and a lubricant (f), wherein the composition (G) comprises an olefin thermoplastic elastomer composition (D) and a mineral oil (e), the composition (D) comprising 50 to 70% by weight of an ethylene/.alpha.-olefin copolymer elastomer (A) having a Mooney viscosity (ML1+4(100.degree. C.)) of 40 to 100, 35 to 21% by weight of a polypropylene resin (B) having a crystal melting point of 140.degree. to 165.degree. C. and an ethylene unit content of 1 to 2% by weight and 15 to 9% by weight of a low-density polyethylene resin (C) having a density of 0.90 to 0.93 g/cm.sup.3 and a crystal melting point of 102.degree.-118.degree. C.

Abstract: A process for preparing an open-cell structure from a vinyl chloride resin. The process includes mixing a vinyl chloride resin, stabilizer, plasticizer, surface active agent, azodicarbonamide and 4,4'-oxybisbenzenesulfonyl hydrazide to form a vinyl chloride resin paste. The vinyl chloride resin paste of step (a) is rendered alkaline, and mixed to form a uniformly-mixed paste. The paste is permitted to expand, and then heated to cause gelation.
