Abstract: A method and a device for using an electrochemical energy store so as to optimize the service life is provided. The cyclical aging of the energy store is expressed in the form of a nonlinear function based on the temperature which can be influenced by a charging and/or discharging process of the energy store and the energy throughput. The nonlinear function is linearly approximated in order to determine the cyclical aging in each interval which can be specified for subdividing a specifiable usage planning period and is used to calculate a service life-optimizing plan for using the energy store.

Abstract: A method, device and assistance system for detecting leaks in an area of a supply network, wherein leaks are detected by comparing real measured values supplied by sensors with measured values ascertained using a Monte Carlo simulation and, in particular, the method ascertains irregularities, which can be attributed to anomalies such as leaks, based on a hydraulic analysis so that existing leaks can be detected. Furthermore, the method can be applied to sensors that are temporarily installed in the network, giving the network operator additional freedom in the leak detection, and can be used for other supply networks and infrastructures.

Abstract: An embodiment of the present invention discloses a method for the computer-aided determination of the dependencies of a plurality of modules of a technical system, especially of a software system. Every module of the system has a known, first consumption of resources. The first consumption of resources of at least one of the modules is modified according to a predetermined criterion, thereby obtaining a modified system. The modified system is executed. A second consumption of resources is measured for every module of the modified system, the consumption resulting from the modification of the first consumption of resources of the at least one module. An analysis of the second consumption of resources of a respective module and the predetermined criterion is used to determine whether there is a dependency between the respective module and the at least one module that is characterized by the modified consumption of resources.

Abstract: In a method for estimating the position of a subscriber station of a radio communication system, a receiver station receives reports from the subscriber station, said reports containing information relating to the signal strength of a receiving signal of at least one transmitting station in the locality of the subscriber station. The reports are stored in a memory of a network device of the radio communication system and a position determining unit takes into account at least two reports stored prior to the request for position estimation, in order to estimate the position of the subscriber station.

Abstract: A fast and simple method evaluates the capacity of OFDM-based radio networks using adaptive modulation and coding. From a mapping of SINR values to achievable data throughput, constant coefficients defining a linear function for the required channel activity of a single user are determined. Subsequently, linear equations for total uplink and downlink channel activity are obtained which allow fast numerical solutions.
