Abstract: A method and a computer system for determining the relevance of a text. The method includes: determining the similarity of the text to texts in a portfolio, where the text is compared with each of the texts in the portfolio as part of an individual comparison while determining a similarity value which indicates the similarity between the two texts in each case; assigning the similarity value to one of the two texts in the respectively performed individual comparison which was published at an earlier time or was first captured by a capture system at an earlier time; calculating a relevance value from the similarity values which were determined in the individual comparisons and were assigned to the text, and storing the calculated relevance value and/or transmitting the calculated relevance value to a communication end system via a computer network.

Abstract: A heat exchanger assembly for a motor vehicle includes a heat exchanger having at least one inlet tank, at least one outlet tank, and a plurality of exchanger tubes of an exchanger core. The exchanger tubes connect the inlet tank and the outlet tank and extend along a transverse axis that extends perpendicular to a longitudinal axis of the motor vehicle. Each exchanger tube defines a fluid passage path for fluid. A first pair of adjacent exchanger tubes form a first air passage path therebetween for ambient air and a second pair of adjacent exchanger tubes form a second air passage path therebetween for ambient air. The first air passage path has an air flow resistance that is different from an air flow resistance of the second air passage path.

Abstract: A method controls a temperature control device of an accumulator of a motor vehicle feeding an electric motor. The method includes a check for the presence of an interaction with a communication input of the motor vehicle 1 and, in the presence of an interaction, outputs a control signal to a temperature control device designed for controlling the temperature of the accumulator to a target temperature in a predetermined temperature range. The control signal causes a change of the temperature control of the accumulator.

Abstract: A vehicle battery insulating system includes an inner wall and outer wall forming an insulating cavity filled with a microporous material such as microporous silica. A vacuum pump is coupled to a first connection of the cavity and a valve is coupled to a second connection of the cavity.
