Abstract: An information processing apparatus selects an excluded element set that is a subset of a tentative element set, from the tentative element set that is at least a part of a solution target element set constituting an optimization problem as a solution target, determines whether or not a tentative mathematical model that is a mathematical model in which an element set excluding the excluded element set from the tentative element set and a constraint condition are formulated, is feasible, in a case where the tentative mathematical model is determined to be infeasible, extracts a list of constraint conditions conflicting with each other from the tentative mathematical model, converts each constraint condition of the extracted list into a name of the constraint condition, and outputs the name of the constraint condition obtained by conversion.

Abstract: In a case of causing an Ising machine to execute a process of solving an optimization problem by obtaining a value of an unknown variable using a first objective function, the value of the unknown variable being correlated with the number of quantum bits used in solving the optimization problem using the Ising machine, an information processing apparatus derives a smallest value for the unknown variable within a range in which a feasible solution of the optimization problem is obtained by using a second objective function different from the first objective function, and performs control of causing the Ising machine to execute a process of solving the optimization problem defined by a mathematical model including the derived value for the unknown variable and the first objective function.

Abstract: An information processing apparatus executes a first process of generating a work shift table in which a constraint condition regarding a work shift of an employee is satisfied, and an output value of an objective function regarding a desire of the employee for the work shift is minimized, the constraint condition being based on a possession skill assigned to each of a plurality of the employees and representing an ability to implement work on a work target, and the number of employees required in a predetermined period, and outputs whether or not a feasible solution exists in the first process.

Abstract: A radiation imaging system includes a plurality of radiation imaging apparatuses each of which includes a radiation detecting unit that performs an imaging operation for capturing a radiation image based on radiation radiated from a radiation generating apparatus, a control apparatus that communicates with the plurality of radiation imaging apparatuses, a calculation unit that calculates information indicating whether a part or all of pixels of the radiation image are saturated, and an image acquiring unit that acquires a radiation image from a radiation imaging apparatus selected from among the plurality of radiation imaging apparatuses based on the information.

Abstract: An information processing apparatus includes a position acquisition section, a point of gaze acquisition section, an amendment section, and a determination section. The position acquisition section acquires an input position to a touch panel. The point of gaze acquisition section acquires a point of gaze of a manipulator. The determination section determines whether the input position and the point of gaze satisfy at least one amendment condition. In cases that the determination section determines that the amendment condition is satisfied, the amendment section amends the input position based on the point of gaze. In cases that the determination section does not determine that the amendment condition is satisfied, the amendment section amends the input position by reducing a degree of an influence of the point of gaze as compared with the cases that the determination section determines that the amendment condition is satisfied.

Abstract: An infant cry muffler cover includes: a cover body including a sound insulation member for insulating a cry of an infant, the cover body having a sheet shape to cover the infant held on a front side of a body of a guardian; an opening portion defined at a central portion of an upper side of the cover body to be opened toward the infant at a neck of the guardian, the opening portion being curved in a direction away from the guardian; a neck string that connects both ends of the opening portion to each other to be put around the neck of the guardian; and a back string that connects both ends of the upper side of the cover body to each other to be put around a back of the guardian.

Abstract: An operation system includes: an operation device manually operated by a user and inputting a command of an operation content to a command target apparatus selected from multiple apparatuses; a selection device selecting one apparatus as the command target apparatus according to multiple visual line regions individually set in relation to the apparatuses and a visual line direction of the user detected by a visual line detection sensor, the one device relating to one visual line region disposed in the visual line direction; and a selection maintaining device maintaining a selection state of the command target apparatus even when the visual line direction is changed to another direction pointing to none of the visual line regions while the command target apparatus is selected.

Abstract: An alerting device, which alerts a driver of a vehicle when the driver is looking at a display unit of a mobile terminal equipped with a camera, includes a gaze determination portion, an alert command portion, and a circumstance determination portion. The gaze determination portion determines whether the driver is looking at the display unit based on an image captured by the camera of the mobile terminal. When the circumstance determination portion determines that a current circumstance is not a gaze allowed circumstance and the gaze determination portion determines that the driver is looking at the display unit, the alert command portion outputs a command to alert the driver of the looking at the display unit. The circumstance determination portion determines that the current circumstance is the gaze allowed circumstance when the vehicle is halted at an intersection by a red traffic light.
