Abstract: The present disclosure provides an OCT imaging system to reduce or eliminate frequency-domain aliasing artifacts. The frequency is shifted using a carrier frequency to define a sampling range substantially centered on the carrier frequency. An image of the sample is generated from a displayed imaging range that consists of a subset of the frequencies within the sampling range. Furthermore, the system may be configured to determine the carrier frequency such that a Nyquist frequency corresponding to the shifted frequency is extended beyond either an upper or a lower bound of an OCT quality envelope corresponding to the first portion of light. Additionally, the carrier frequency may be determined such that a lower bound of the OCT quality envelope is greater or less than a zero-frequency DC limit.

A first air duct is provided for supplying air to the at least one cylinder of the internal combustion engine for operating the internal combustion engine and a second air duct is provided for supplying air to a heater for heating an exhaust system of the internal combustion engine. The first and second air ducts are connected by a third air duct to an air filter, for providing filtered ambient air to the internal combustion engine. The first and second air ducts in each case have at least one control element for controlling the amount of air flowing through. The second and third air ducts in each case have a mass flow sensor for measuring a mass of the air flowing through the relevant air duct.

Abstract: A mechanism is provided in a data processing system for automatic determination of b-value difference from diffusion-weighted (DW) images. The mechanism receives a series of images wherein a first image has a first b-value and a second image has an unknown b-value. The mechanism applies a generative adversarial network (GAN) model to estimate a difference between b-values in the series of images. The mechanism determines a b-value for the second image based on the first b-value and the estimated difference between b-values.

Abstract: A method and a device for diagnosing an air supply of an internal combustion engine which includes a first air duct for supplying air to a cylinder and a second air duct for supplying air to a heater for heating an exhaust system. The first and second airs ducts each have a mass flow sensor for measuring a mass of the air flowing therethrough, a pressure sensor for measuring the pressure in the air duct, and a temperature sensor for measuring the temperature of the air flowing therethrough. The first and second air ducts originate from a common air filter. Depending on operating states of the cylinders and heater, measured values of the mass flow sensors, pressure sensors, and temperature sensors of the first and second ducts are compared with one another or with comparison values, and a result of the diagnosis is ascertained depending on the comparison.
