Finally signals representing the processed signals are outputted.

Abstract: A process for forming a thin film of a given material includes providing a first substrate having, on the surface, an amorphous and/or polycrystalline film of the given material and a second substrate is bonded to the first substrate by hydrophobic direct bonding (molecular adhesion), the second substrate having a single-crystal reference film of a given crystallographic orientation on the surface thereof. A heat treatment is applied at least to the amorphous and/or polycrystalline film, where the heat treatment causes at least a portion of the amorphous and/or polycrystalline film to undergo solid-phase recrystallization along the crystallographic orientation of the reference film, where the reference film acts as a recrystallization seed. The at least partly recrystallized film is then separated from at least a portion of the reference film.

Abstract: A system and method for determining end-to-end available bandwidth of a path in a packet-switched communication network. A multi-rate packet chirp injector injects probe traffic packets at different probing rates, u, into the network utilizing a probe chirp. A receiver samples time separation of the probe traffic packets to generate time-separation samples, which are used to calculate relative inter-packet separation strain, ?, samples at different probing rates. An Expectation-Maximization, EM, analyzer utilizes an EM algorithm to identify useful strain ? samples and to estimate parameters of a line l2 representing a direct linear relationship between the probing rate and the inter-packet separation strain ? at probing rates greater than a break point. A filter such as, for example, a Kalman filter then determines the available bandwidth of the network path based on the estimated parameters of the line l2.

Abstract: Soft bit values are generated for received symbols transmitted based on a modulation constellation by demodulating the received symbols via a sequence of demodulation stages, each demodulation stage producing a symbol decision based on an effective constellation. Each effective constellation used by a non-final one of the demodulation stages includes subsets of centroids approximating a region of the modulation constellation. Adjacent ones of the subsets have one or more common points so that at least two adjacent subsets overlap. The soft bit values for the symbol decisions are determined based on detection metrics computed during demodulation for the points included in the effective constellation constructed incrementally over the sequence of demodulation stages, the effective constellation produced by the final demodulation stage being devoid of one or more points included in the modulation constellation.

Abstract: A method of interworking CS (Circuit Switched) video calls with video calls using IP multimedia protocols is provided. According to the method, an interworking function receives signalling comprising an indication of the codec capability of a CS terminal involved in the CS video call, as part of a MONA (Media Oriented Negotiation Acceleration) negotiation. Thereafter IP codec negotiation is initiated. And thereafter the MONA negotiation is continued and/or completed. Thus the codec capabilities and/or preferences of the CS terminal can be taken into account during the IP codec negotiation with the IP endpoint.
