Abstract: A system for determining cardiovascular characteristics is to be disposed on the body of a subject. The body has a detection area. The system includes a detector member and a processor. The detector member includes at least sixteen precordial electrodes which are to be placed on the chest of the subject within the detection area and which produce at least sixteen electrocardiogram (ECG) signals. The processor calculates at least twenty-four characteristic values based on the ECG signals. The characteristic values serve as basis for determining a location of chronic or acute myocardial ischemia in the body and a region of chronic or acute myocardial ischemia in the heart of the subject.

Abstract: The present application describes various methods and devices for providing content to users. In one aspect, a method includes, for each content item of a set of content items, obtaining a score for the content item using a recommender system, the score corresponding to a calculation of subsequent repeated engagement by a user with the content item. The method also includes ranking the set of content items based on the respective scores and providing recommendation information to the user for one or more highest ranked content items in the set of content items.

Abstract: A CO2 recovery system and a CO2 recovery method include an absorption apparatus that causes CO2 in an exhaust gas to be absorbed by CO2 absorption liquid, a regeneration apparatus that heats the CO2 absorption liquid to separate CO2; a CO2 compression mechanism of a first turbine driving mechanism that is driven in conjunction with a first steam turbine to compress separated CO2, a reheating boiler that supplies LP steam exhausted from the first steam turbine in order to heat the CO2 absorption liquid, an auxiliary boiler that heats condensed water of the LP steam after the CO2 absorption liquid is heated to generate HP steam and supplies the HP steam to the first steam turbine, and a second turbine driving mechanism that supplies the HP steam generated in the auxiliary boiler to a second steam turbine and is driven in conjunction with the second steam turbine.

Abstract: A heat recovery system includes a preheater (4) in which heat exchange is performed between condensed water generated in a condenser (3) and CO2 in a CO2 recovery apparatus, a gas heater (5) in which heat exchange is performed between the condensed water heated in the preheater (4) and exhaust gas discharged from a boiler (7) and the boiler (7) to which the condensed water heated in the gas heater (5) is supplied as boiler supply water. With this configuration, an amount of steam extracted from a low-pressure steam turbine (2) is reduced.

Abstract: There is provided an exhaust gas treatment system including a CO2 recovery unit with further enhanced energy efficiency. An exhaust gas treatment system (1) of the present invention includes: a CO2 recovery unit (10) including a CO2 absorption column (11), an absorbing solution regeneration column (16), and a reboiler (21); and an exhaust gas heat exchanger (5) provided on a gas upstream side of the CO2 recovery unit (10). Heat exchange is performed between process condensate discharged from the CO2 absorption column (11) and steam condensate discharged from the reboiler (21) in a heat exchanger (22). The heated process condensate is fed to the absorbing solution regeneration column (16). Heat exchange is performed between the cooled steam condensate and exhaust gas in the exhaust gas heat exchanger (5) so that the steam condensate is heated while the exhaust gas is cooled.
