  • Publication number: 20190298207
    Abstract: Provided is a method of analyzing brain activities for realizing a biomarker for neurological/mental disorder, based on brain function imaging. From measured data of resting-state functional connectivity MRI of a healthy group and a patient group, correlation matrix (80) of degree of brain activities among prescribed brain regions is derived for each subject. Feature extraction is executed by regularized canonical correlation analysis (82) on the correlation matrix (80) and attributes of the subject including a disease/healthy label of the subject. Based on the result of regularized canonical correlation analysis, by discriminant analysis (86) through sparse logistic regression, a discriminator (88) is generated.

    Abstract: [Problem] To provide a calibration apparatus capable of reducing a workload for calibrating a position and a direction of each range sensor. [Solving Means] In the measurement arithmetic unit 100, the social group identification portion 5610 identifies a group candidate that is detected as a group out of moving measuring objects in each laser range finder. The group comparison portion 5612 identifies a group in agreement for each pair of the laser range finder, and calculates the relative position of each pair of the laser range finder according to the position and the directions of the identified matching group. The network position identifying portion 5620 calibrates the position and the direction of each laser range finder in the sensor network coordinate system such that the error of the position of the object observed in common from each pair becomes minimum.

  • Publication number: 20170231787
    Abstract: [Object] To provide a hybrid actuator attaining both driving force and responsiveness, capable of reducing inertia of a movable portion. [Solution] A pneumatic air muscle has a cylinder (112) provided in a flexible member (100) forming a pneumatic artificial muscle. At the center of an upper lid element (109) of the cylinder, a through hole is opened, and an inner wire (103) of a Bowden cable passes through this through hole and is coupled by means of a spring (106) to a bottom portion of the cylinder. When the pneumatic artificial muscle contracts, the inner wire (103) and the pneumatic air muscle move together because of the stopper (105), and the contraction force is transmitted. In contrast, when the pneumatic air muscle extends, the stopper (105) is disengaged, while the tension of inner wire (103) is kept by the spring (106) to prevent slacking.
