Abstract: The cooking device comprises a housing, a carrier, a first heating element, a second heating element, a fan, and a controller. The controller is electrically connected to the first heating element, the second heating element, and the fan. The cooking modes of the cooking device comprise a first cooking mode and a non-first cooking mode, the first cooking mode is at least configured for cooking pizza. Since the first rotational speed of the fan in the first cooking mode is not greater than the non-first rotational speed of the fan in the non-first cooking mode, the fan rotational speed in the first cooking mode is set to be slower. The slower rotational speed of the fan prevents the toppings composed of vegetables, fruits, and other ingredients on the upper surface of the pizza from drying out quickly, thereby maintaining good texture of the ingredients.

Abstract: A cooking device and cooking method. The cooking device comprises a housing, a carrier, a first heating element, a second heating element, a fan, and a controller. The controller is electrically connected to the first heating element, the second heating element, and the fan. The cooking modes of the cooking device comprise a first cooking mode and a non-first cooking mode, the first cooking mode is at least used for cooking pizza.

Abstract: Blood flow information is extracted from speckle information of a time series of structural optical coherence tomography (OCT) images. Flow information can be determined from high-frequency information of the OCT images, a speckle density of the OCT images, from a co-occurrence matrix applied to the OCT image, from a machine learning analysis of an input OCT image, or the like. A flow profile analogous to a pulse waveform is then generated as a time series of the extracted flow information.
