Abstract: Method and device for processing a communication network A method and a device for processing a communication network are provided, wherein (a) a first performance parameter of the communication network is determined; (b) a third performance parameter is determined based on the first performance parameter and a second performance parameter, which second performance parameter was previously determined, wherein the second performance parameter comprises a forecast of an expected network performance over time until the end of the scheduled lifetime of the communication network; and (c) the communication network is processed based on the third performance parameter. Furthermore, an according computer program product is suggested.

Abstract: A process of isolating a REE or a group of REE from a solution or dispersion containing said REE or said group of REEs comprising the following steps: (i) preparing a mixture comprising said solution or dispersion and biomass comprising at least one organism selected from any one of the following organism classes: eubacteria, archaea, algae, and fungi, whereby the at least one organism is capable of adsorbing or accumulating said REE or said group of REEs; (ii) incubating said mixture of step (i) for allowing the adsorption or accumulation of said REE or said group of REEs by said biomass; (iii) separating the biomass having adsorbed or accumulated REE(s) from the mixture of step (ii); and (iv) isolating said REE or said group of REEs from said biomass separated in step (iii).

Abstract: A method and an apparatus for producing a chip-substrate connection by alloying or brazing, using a solder containing two or more components with at least two metal-containing constituents X and Y. The first constituent X contains in particular gold or a similar precious metal, and the second constituent Y being consumed in the soldering operation by reacting or being dissolved in the materials or layers which are to be joined. The solder has a hypereutectic concentration of the second constituent Y. The invention furthermore relates to a solder for the production of a chip-substrate connection, and to a semiconductor component with a semiconductor chip which is secured to a substrate by alloying or brazing.

Abstract: A process for operation of a laser device (1) is described, whereby circulating light pulses each comprising spectral components according to a plurality of longitudinal modes of a resonator configuration (3) are generated in the resonator configuration (3) and subjected to a compensation of group velocity dispersion, and a predetermined linear dispersion is introduced into the light path of the resonator configuration (3), so that at least one mode has a predetermined frequency and/or the mode distance between the modes has a predetermined value. Furthermore, regulations for stabilizing the laser device on the basis of this process and applications of the regulations for the generation for stabilized, ultra-short light pulses, generation of optical frequencies and in the frequency and/or time measuring technique as well as in the spectroscopy are described.
