Abstract: A non-transitory computer-readable medium (CRM) storing computer program code executed by a computer processor that executes a process, an information processing apparatus, and model generation method that generates an image of a lumen organ. The process includes acquiring a first image obtained by imaging a lumen organ of a patient based on an ultrasound signal of a first frequency; and generating a second image by inputting the acquired first image into a model, the model being learned to generate, when the first image is input, the second image in which the lumen organ is imaged based on an ultrasound signal of a second frequency. Preferably, the second image, in which a part of an image region of the first image is converted into the second frequency, is generated using the model, and a synthesis image is generated in which the second image is superimposed to the first image.

Abstract: This engine comprises an engine body and an ECU. The ECU is configured to execute a high idling limitation when a prescribed condition is fulfilled during startup. When executing a high idle limitation, the ECU determines a first upper limit speed, which is an upper limit value of high idling speed, and a first limitation time, which is a time during which the high idling limitation continues, on the basis of the engine temperature during startup. Based on the temperature of the environment, the ECU determines a second upper limit speed, which is an upper limit value of high idling speed, and a second limitation time, which is a time during which the high idling limitation continues. The ECU executes the high idling limitation based on either the determined first upper limit speed or second upper limit speed, and either the first limitation time or the second limitation time.
