Abstract: A method for evaluating the deceleration law of a vehicle including an accelerator pedal, a brake pedal, and a powertrain including an engine, a gearbox and a unit for disconnecting the engine and gearbox, the deceleration law being defined for a discrete state of the powertrain. The method includes a first step of evaluating driving parameters, including measuring the speed (v) of the vehicle, evaluating the engaged gearbox ratio, evaluating the state of closure of the disconnecting unit, detecting the position of the accelerator pedal, detecting the position of the brake pedal, evaluating the slope (a) of the road on which the vehicle is traveling, evaluating the mass (m) of the vehicle. If the accelerator pedal is in a released position and if the brake pedal is in a released position, a second step including recording the speed (v) of the vehicle and the slope (a) of the road.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for presenting content items. In one aspect, a method includes obtaining, for each of one or more first applications, a user's level of interest in obtaining content based on a number of user requests for content from the application that result in less than a given amount of content being presented to the user. Based on one or more obtained levels of interest, a content item for a second application that has available content is selected. The second application can be different from the first application. The content item is displayed on a display of a user device.
