Abstract: A wireless communication characteristics evaluation method for evaluating wireless communication characteristics of a wireless communication system where a plurality of wireless communication terminals perform communication by transmitting or exchanging signals, the wireless communication characteristics evaluation method including: a step 1 of acquiring power and a band of an interference signal; a step 2 of calculating an interference band rate showing a rate of the band of the interference signal that overlaps with a band of a desired signal; a step 3 of calculating an interference power rate from interference power and the interference band rate and furthermore, calculating steady noise power from the interference power and the interference power rate; a step 4 of determining a real SINR from received power of the desired signal and the steady noise power; and a step 5 of determining wireless communication characteristics of the desired signal from the real SINR.

Abstract: This supercharger for a motorcycle is driven by power of a crankshaft of a combustion engine, and compresses intake air to be supplied to the combustion engine. The supercharger has an impeller of a centrifugal type, and an intake air control valve is disposed on the upstream side of the impeller of the supercharger with respect to a flow direction of the intake air. The intake air control valve is disposed so as to face a suction port of the supercharger in the flow direction of the intake air. The intake air control valve adjusts the amount of the intake air flowing into the impeller, and in addition, provides a preswirl to the intake air flowing into the impeller.

Abstract: An object of the present invention is to provide a novel method of controlling TYLCV whereby the infection cycle of TYLCV can be broken. The present invention provides a novel virus that is not transmitted by an insect vector as a tomato yellow leaf curl virus. The present invention also provides a method of controlling a tomato yellow leaf curl disease and a method of preventing transmission of a yellow leaf curl virus by using a tomato yellow leaf curl virus not transmitted by an insect vector.

Abstract: In a wave form signal generating apparatus designed to memorize a desired wave form in the form of a floating point representation for generating a wave form signal based on the memorized wave form, a mantissa and an exponent of a sampling data of the desired wave form are memorized in a predetermined number of digits as a compressed information, and a digit number of the memorized exponent allotted in the predetermined number of digits are further momorized. The memorized exponent is extracted on a basis of the memorized digit number so that the wave form signal is reproduced on a basis of the extracted exponent and the mantissa allotted in the remaining portion of the predetermined number of digits.
