Spatially resolved quantitative mapping of thermomechanical properties and phase transition temperatures using scanning probe microscopy
An approach for the thermomechanical characterization of phase transitions in polymeric materials (polyethyleneterephthalate) by band excitation acoustic force microscopy is developed. This methodology allows the independent measurement of resonance frequency, Q factor, and oscillation amplitude of a tip-surface contact area as a function of tip temperature, from which the thermal evolution of tip-surface spring constant and mechanical dissipation can be extracted. A heating protocol maintained a constant tip-surface contact area and constant contact force, thereby allowing for reproducible measurements and quantitative extraction of material properties including temperature dependence of indentation-based elastic and loss moduli. |

Unified pulse shaping for multi-carrier and single-carrier waveforms
To transmit a multi-carrier signal, a transmitter provides zero symbols for guard subbands, performs OFDM modulation, and filters the resultant time-domain samples with a pulse shaping filter. To transmit a single-carrier signal, the transmitter partitions the single-carrier signal into segments. Each segment contains up to K samples and is padded, if needed, to the length of an OFDM symbol. Each padded segment is transformed from the time domain to the frequency domain to generate a corresponding frequency-domain segment with K symbols. For each frequency-domain segment, the symbols corresponding to the guard subbands are set to zero. Each frequency-domain segment is then transformed from the frequency domain to the time domain to generate a corresponding time-domain segment. A cyclic prefix may or may not be appended to each time-domain segment. Each time-domain segment is filtered with the same pulse shaping filter to generate an output waveform for the single-carrier signal. |

Computing time-decayed aggregates under smooth decay functions
Aggregates are calculated from a data stream in which data is sent in a sequence of tuples, in which each tuple comprises an item identifier and a timestamp indicating when the tuple was transmitted. The tuples may arrive at a data receiver out-of-order, that is, the sequence in which the tuples arrive are not necessarily in the same sequence as their corresponding timestamps. In calculating aggregates, more recent data may be given more weight by a decay function which is a function of the timestamp associated with the tuple and the current time. The statistical characteristics of the tuples are summarized by a set of linear data summaries. The set of linear data summaries are generated such that only a single linear data summary falls between a set of boundaries calculated from the decay function and a set of timestamps. Aggregates are calculated from the set of linear data summaries. |

Method for a cloud-based meta-file system to virtually unify remote and local files across a range of devices' local file systems
A system and process that establish a singular shared file system among devices in order to create a virtual representation of data on all of the devices via metadata indexing.

The invention relates to a method, an arrangement and a device for transmitting information between a central unit (DSLAM) and at least one decentralised unit (TN1, TN2, TN3) in a communication network. During, for example, the training phase in a decentralised unit (TN1, TN2, TN3), a distance between the at least one decentralised unit (TN1, TN2, TN3) and the central transmission unit (DSLAM) is estimated and a value (kl0) representing said distance is transmitted to the central unit (DSLAM). In the central unit (DSLAM), a value (kl0′) representing a fictional distance is calculated using the transmitted value (kl0) and said value (kl0′) is transmitted to the decentralised unit (TN1, TN2, TN3). Subsequently, information is transmitted in accordance with the value (kl0′) representing the fictional distance. |

Satellite communication system utilizing low density parity check codes
An approach for reliably communicating over a satellite in support of a communication service including, for example, as direct broadcast satellite and data service, is disclosed. An input message is encoded, yielding a structured Low Density Parity Check (LDPC) coded message. The coded message is modulated according to a high order modulation scheme that has a signal constellation representing more than two symbols per signaling point—e.g., 8-PSK (Phase Shift Keying) and 16-QAM (Quadrature Amplitude Modulation). The system includes a transmitter configured to propagate the modulated signal over the satellite. The above approach is particularly applicable to bandwidth constrained communication systems requiring high data rates. |
