Abstract: An information processing apparatus comprising at least one processor, wherein the processor is configured to: acquire at least one optical image obtained by optically imaging a subject; acquire at least one radiation image obtained by radiography of the subject from a direction substantially the same as an imaging direction of the optical imaging; estimate a position of at least one first region of interest based on the optical image; and specify a second region of interest corresponding to the position of the first region of interest in the radiation image.

Abstract: An information processing apparatus comprising at least one processor, wherein the processor is configured to: acquire at least one optical image obtained by optically imaging a subject from a first direction; estimate a position of at least one first region of interest based on the optical image; acquire a plurality of radiation images obtained by continuously performing radiography of a state in which the subject swallows a sample from the first direction; specify a second region of interest corresponding to the position of the first region of interest in the radiation image; monitor a position of the sample based on the plurality of radiation images; and change an imaging condition for the radiography based on a positional relationship between the second region of interest and the sample.

Abstract: An electronic apparatus includes a display, a change unit, and a specification unit. The change unit changes a specification algorithm for specifying an operation with respect to the display according to a start position of the operation. The specification unit specifies the operation based on the specification algorithm.

Abstract: A fuel-lean mixture burns in rows of flame ports each located between a pair of rows of flame ports burning a fuel-rich mixture. The fuel-rich flames support and stabilize the fuel-lean flames to stabilize combustion and to avoid flame liftoff and noise. The fuel-lean flames reduce the temperature of the overall flame, and thereby reduce the production of No.sub.x compounds produced by the burner. Stepwise and proportional burner control techniques are disclosed.

Abstract: A water heater with reduced nitrogen oxides output utilizing NO.sub.x reducing water conduits to cool a laminar flame and thereby reduce production of nitrogen oxides, The water heater has a partially aerated burner using a partially premixed combustion method to produce the laminar flame wherein a plurality of NO.sub.x reducing water conduits are disposed above the partially aerated burner in such a manner that water is supplied from a cold water conduit or a hot water conduit of the water heater into the plurality of NO.sub.x reducing water conduits through a water introducing portion by means of branching or serial connections. The water absorbs heat while flowing through the plurality of NO.sub.x reducing water conduits and is returned to the cold water conduit or the hot water conduit through a water receiving portion by means of and branching or serial connections.

Abstract: A small combustion apparatus for domestic or commercial use, wherein the quantity of combustion is increased by enhancing the mounting density of the burner units and to stabilize combustion using a lean fuel mixture resulting in a decreased generation of nitrogen oxides and noise. The burner has first and second burner units, arranged alternatively adjacently to one another. Each of the burner units has a flame port portion at the top of the burner body vertical and flat, has an inlet for fuel gas and air at the bottom of the burner body, has a mixing channel extending from the inlet to the flame port portion; and has inlets of the first burner units located below the inlets of the second burner units fuel gas spouts, are provided to correspond to the respective inlets of the first and second burner units.
