Abstract: A system for automatic testing of a software application while the software application is running, e.g. on another system, is configured to obtain a test script specification associated with a software component of the software application. A test step comprised in the test script specification comprises a reference to a process definition stored in a catalog but not implemented by the software component. The system is further configured to determine whether a further software component of the software application implements the process definition, create a new version of the test script specification in which the reference to the process definition has been replaced with a reference to an implementation of the process definition in the further software component in dependence thereon, create a test script based on the new version, and control the software application by simulating user input according to the test script.

Abstract: A method is provided for heating a lubricating system. At low temperatures, lubricating oil has a high viscosity which requires more energy to be overcome than at higher temperatures. The method speeds up the heating behavior and thereby reduces the energy requirement of lubricating systems. The method can be used to heat lubricating systems for combustion engines or transmissions, preferably automatic transmissions, including at least one oil suction tube which is disposed in an oil sump and an oil bypass line bypassing the oil return lines. A bypass valve is disposed in the oil bypass line.

Abstract: A line system (24) for a road miller, which rotates along with the milling roller (11) and which supplies water directly to the nozzles (23) which are arranged on the lateral surface (18) of the milling roller (11), to be arranged in the milling roller (11). Owing to the line system (24), the milling roller (11) no longer needs to be filled with water. The nozzles (23) are instead supplied with water directly from the line system (24) in order to spray the milling region selectively.

Abstract: A method for generating a network, in particular a telecommunications, water, long-distance heat supply, or power network, the network connecting all users to a main distribution node depending on the existing or definable local needs and requirements of the individual users. A graph is generated which is composed of edges and nodes. The graph includes all technically feasible and/or definable transmission paths of the network. The length and direction of the edges are derived from the real topography of the street segments and definable cable paths of the territory to be supplied by the network. The nodes form the intersections between the edges or streets and/or cable paths. The users are assigned to the graph in such a way that each user is connected to the closest edge or the closest node of the graph by an additional service edge.

Abstract: A system and method are provided to increase the horsepower of an induction motor. One technique for increasing the horsepower of a motor is to connect the motor to a variable speed drive that is providing an output voltage and frequency greater than the standard line voltage and frequency. The connection of the variable speed drive to the induction motor enables the motor to be operated in constant flux or constant volts/Hz mode and provide a greater output horsepower. Another technique for increasing the horsepower of a motor is to use a dual voltage motor configured for lower voltage operation and then provide the motor with the corresponding voltage and frequency for higher voltage operation. The higher voltage and higher frequency can be provided by a variable speed drive with or without voltage boost. A variable speed drive without voltage boost, but with frequency boost, can be used in situations where the standard main voltage is greater than the lower voltage rating.

Abstract: A system and method are provided for variable speed operation of a screw compressor to obtain increased capacity and efficiency. The screw compressor is connected to an induction motor driven by a variable speed drive, wherein the screw compressor has a variable output capacity that is dependent on the output speed of the motor. To obtain increased capacity and efficiency, the screw compressor is operated at a speed greater than the screw compressor's rated speed and does not include a slide valve. The maximum operating speed of the screw compressor, which speed is greater than the rated speed, is related to the maximum operating speed of the motor when operated at a voltage and frequency provided by the variable speed drive that is greater than the motor's rated voltage and frequency in a constant flux or constant volts/Hz mode.
