Abstract: In a measurement unit, a primary acceleration sensor is fixed at the center of gravity of a flying object or at a position within a certain error range from the center of gravity. A secondary acceleration sensor is fixed inside the flying object so as to be spaced from the center of gravity of the flying object. In a measurement apparatus, an acquirer acquires a primary acceleration measured by the primary acceleration sensor during flight of the flying object and a secondary acceleration measured by the secondary acceleration sensor during the flight of the flying object. An estimator estimates a spin rate per unit time of the flying object from the acquired primary acceleration and the acquired secondary acceleration using maximum likelihood estimation.

Abstract: A vascular viscoelasticity evaluation device and method in which, a pulse wave obtained using a cuff is subjected to first derivation, a positive amplitude peak value Vf1 that occurs first and a negative amplitude peak value Vr2 that occurs second out of a plurality of negative amplitude peak values are detected in a state in which an external force substantially the same as or greater than the systolic blood pressure has been exerted on a blood vessel, and a ratio of the positive amplitude peak value Vf1 that occurs first to the negative amplitude peak value Vr2 that occurs second is calculated, and then the vascular viscoelasticity is evaluated on the basis of this calculated ratio.

Abstract: To measure three-dimensional dose distributions with a dosimeter, such as a gel dosimeter. In an embodiment of the present invention, provided is a gel dosimeter having water, as solvent or disperse medium, clay particles that swell with water, and recording material precursor, which are dissolved or dispersed with each other. The recording material precursor has an atom or ion, wherein the atom or ion changes its valence number by reacting with both of a radical and a molecular radical derivative. The radical is to be generated from the water ionized by irradiation of radiation rays, and the molecular radical derivative is a molecule to be formed by bonding the radicals with each other. By the time radiation rays are irradiated, the gel dosimeter has been free from a substance identical to the molecular radical derivative and has lost fluidity.

Abstract: Assuming that there are three continuous frames, i.e, cross sectional images of an organism, a dummy region of interest (ROI) is specified manually in the first frame, a temporary ROI is set in the second frame at the same position as that of the dummy ROI in the first frame. Whether a specific region in the second frame is inside or outside of a true ROI is judged based on the initial judgment criterion and values of pixels in the specific region. Whether a specific region in the third frame is inside or outside of the true ROI is judged based on values of pixels of regions that have been judged to be inside the region of interest in the second frame.

Abstract: A method of storing substantial data integrating shape and physical properties comprising (A) inputting external data 12 consisting of boundary data of an object 1, (B) dividing, by modified Octree division, the external data into cubical cells 13 which boundary surfaces are orthogonal to each other, and (C) storing the values of various physical properties for each of the cells. Furthermore, in step (B), each of the divided cells 13 is classified to non-boundary cells 13a located in the interior of the object or in a region outside of the object, and boundary cells 13b including boundary surfaces. Thereby, substantial data integrating shape and physical properties can be stored in small storage capacity, thus enabling the integration of CAD and simulation.
