Abstract: Methods and systems for generating a composite image in remote sensing applications are described. In an example, a device can receive an image having a plurality of points specified in an image space. The device can extract a portion of the image and transform points among the extracted portion from the image space to a parameter space defined by a distance parameter and an orientation parameter. The device can identify a set of intersection points in the parameter space that indicate at least one occurrence of a geometry feature in the extracted portion of the image. The device can augment the portion of the image with a plurality of new pixels based on the identified set of intersection points. The device can generate a composite image using the augmented image, where the composite image can include a plurality of augmented images corresponding to other portions of the image.

Abstract: A computer-implemented method includes accessing, by a processing unit, an existing layer representing geospatial-temporal data at a selected timestamp. A first overview layer of the existing layer is generated by iteratively aggregating each cluster of cells of the existing layer into a corresponding lower-resolution cell of the first overview layer. The first overview layer therefore has a lower resolution than the existing layer. A query is received related to the geospatial-temporal data in the existing layer, and the query is processed with reference to the first overview layer.

Abstract: In an approach for efficient flood water analysis from spatio-temporal data fusion and statistics, a processor classifies regular waters by using cartographic data in a first location. A processor generates a water stream network including a watershed based on elevation data. A processor performs statistical analysis of spectral information from a multi-spectral satellite imagery over water bodies including the regular waters and flood waters. A processor correlates the spectral statistics of the multi-spectral satellite imagery to kinetic energy of the flood waters using machine learning techniques and physical modeling. A processor builds a learning model based on the correlation between the spectral statistics and the flood waters with the kinetic energy. A processor estimates kinetic energy of flood waters in a second location using the learning model. A processor evaluates a flooding risk for the second location based on the estimated flood waters kinetic energy.

Abstract: The invention relates to a connection device for an electrical consumer which is provided with an internal energy source so that, when an external energy source is connected, the internal energy source and the external energy source form a hybrid energy source. The connection device comprises an interconnection designed in such a way that an external energy source connected to the connection device (i) exclusively supplies the consumer with energy in a lower load range and (ii) in a higher load range supplies the consumer with energy in conjunction with the internal energy source. The invention also relates to an interface or an electrical consumer having such a connection device.

Abstract: The present invention relates to a method for monitoring the amount of fluid in a fluid container, wherein the amount of fluid contained in the fluid container is determined at a first moment in time, said step comprising reading out information provided on the fluid container, and wherein, at a second moment in time, the amount of fluid is determined that has been removed between said first and second moments in time, and wherein at least one quantity is stored, which is representative of the amount of fluid contained in the fluid container at said second moment in time. Furthermore, the invention relates to a fluid container comprising an information storage means which is adapted to have stored therein the amount of fluid contained in the fluid container or at least one other quantity that is representative of the amount of fluid contained in the fluid container. The invention additionally relates to a system for using such fluid containers.

Abstract: An apparatus for the selective catalytic oxidation of carbon monoxide contained in a hydrogen-rich mixed gas flow, includes a reaction chamber filled with a catalyst and a cooling chamber through which a coolant flows formed between successive plates. The plates have openings that form inlet and outlet channels for the mixed gas flow and the coolant. An oxidizing gas is supplied directly into the inlet channel for the mixed gas flow. For two-stage apparatuses, a separating plate without an opening for the inlet channel for the mixed gas flow is arranged between the first and the second stage, and an apparatus for supplying the oxidizing gas to the second stage is passed into the outlet channel for the mixed gas flow from the first stage.

Abstract: The present invention relates in general to mains-independent power supply and in particular to a housing for a mobile power supply device, wherein there are provided at least one housing section for accommodating at least one fuel cell device, at least one housing section for accommodating at least one electric consumer, and at least one housing section for installing a fuel tank or for insertion of a replaceable fuel cartridge.

Abstract: An evaporator stack, in particular for a double evaporator, includes foils for converting a liquid medium into a gaseous medium. The foil stack has at least one foil through which a medium flows and at least one additional foil. The foil stack has an inlet region for the liquid medium and a discharge region for the gaseous medium. The discharge region is designed such that a pressure gradient in the medium over the at least approximately entire width of the discharge region is smaller than a pressure gradient in the medium over the at least approximately entire length of the media foil through which flow occurs.

Abstract: A lamina stack for a two-pass evaporator composed of laminae for converting two media mass streams from a liquid state into a gaseous state, comprises at least two laminae. Structures comprising recesses and raised regions on a first media lamina form a first media chamber perfused by one of the media mass streams. The structures on a second media lamina form a second media chamber perfused by the other one of the media mass streams. The at least two of the laminae can be supplied with thermal energy. Both media laminae have comparable structures, with at least a majority of the recesses in the one of the media laminae being disposed above or below the raised regions of the respective other media lamina.

Abstract: A method is used for operating a gas generation system in a motor vehicle. A hydrogen-containing gas is generated in the gas generation system from a starting material which contains at least a proportion of liquid hydrocarbon as fuel. The hydrogen-containing gas is used to operate a fuel cell which provides the on-board power supply to the motor vehicle.
