Abstract: A method for determining a maximum transmission capacity, TCAPMAX-OL, of an optical link, OL, within an optical network includes loading an optical transmission spectrum of the optical link, OL, being partially occupied by at least one data traffic carrying channel, CH, with amplified spontaneous emission, ASE, noise spectrally shaped such that the transmission performance of the optical transmission spectrum fully occupied with data traffic carrying channels, CHs, is matched. The method further includes determining the maximum transmission capacity, TCAPMAX-OL, of the optical link, OL, on the basis of measured link data transported through the optical link, OL, via the at least one data traffic carrying channel, CH.

Abstract: Transform block coding is performed very efficiently in terms of computational complexity and compression ratio, by coding the magnitude bits of the transform coefficients distributed in a matrix, in which the magnitude bits of the spectral coefficients are arranged column-wise with the spectral coefficients of the transform block ordered along a row direction of the matrix. That is, magnitude bits within a certain column of the matrix belong to a certain spectral coefficient, while magnitude bits within a certain row of the matrix belong to a certain bit plane. In this configuration, the distribution of non-zero magnitude bits may be condensed towards one corner of the matrix, corresponding to, for instance, the least significant bit plane and corresponding to, by using a scan order among the transform coefficients which sorts the transform coefficients generally in a manner from lowest to highest frequency, the lowest frequency. Various low complexity variants are presented.

Abstract: A method of forming an electronic structural element having a stack including first and second electrode layers arranged alternatively with material layers is disclosed. A stack is formed with the first electrode layers projecting beyond a first lateral side of the stack and the second electrode layers spaced radially inward from the first lateral side. A first contacting structure that contacts each first electrode layer is applied directly to the first side of the stack, which contacting structure embeds such the projecting first electrode layers in an electrically conductive manner. A second contacting structure is formed by exposing the first and second electrode layers at a second side of the stack, forming, by an additive method, a solvent-free insulating structure that electrically insulates the first electrode layers, and applying an electrically conductive material over the solvent-free insulating structure to form the second contacting structure that contacts each second electrode layer.

Abstract: The invention relates to a process for the production of mold-foamed poly(meth)acrylimide (P(M)I) cores, in particular of polymethacrylimide (PMI) cores, which can be used by way of example in automobile construction or aircraft construction. A feature of this process is that polymer granules or polymer powder preheated under pressure are moreover charged under pressure to a compression mold where they are foamed with depressurization. In particular, a feature of the process is that it optionally uses a preferably two-shell compression mold for the heating and also for the cooling of the granules and, respectively, the rigid foam core formed therefrom.

Abstract: A coding efficiency improvement is achieved by performing bit-plane coding in a manner so that coefficient groups for which the set of coded bit-planes is predictively signaled in the datastream, are grouped in two group sets and if a signal is spent in the datastream which signals, for a group set, whether the set of coded bit-planes of all coefficient groups of the respective group set are empty, i.e. all coefficients within the respective group sets are insignificant. In accordance with another aspect, a coding efficiency improvement is achieved by providing bit-plane coding with group-set-wise insignificant signalization according to the first aspect as a coding option alternative relative to the signalization for group sets for which it is signaled that there is no coded prediction residual for the coded bit-planes for the claim groups within the respective group set.

Abstract: A level-‘n’ cache and method are disclosed. The level-‘n’ cache method comprises: in response to a data access request identifying an address of a data block to be accessed, interrogating an address cache of the level-‘n’ cache arranged to store address portions for a sub-set of data blocks stored in a main cache of the level-‘n’ cache to determine whether a cache hit occurs within the address cache for the address. In this way, providing the address cache which is separate from the main cache, with the address cache storing address portions relating to data blocks stored in the main cache, the amount of data required to be stored in the address cache is reduced, and decouples the size of the address cache from that of the main cache which enables the address cache to be sized independent of the size of the data blocks stored in the main cache.

Abstract: Embodiments of the invention concern coders, e.g. a decoder for decoding a sequence of portions of media from a data stream.
