20110295599 | Aligning Scheme for Audio Signals - Methods, devices, and computer programs described herein may segment a reference signal that corresponds to a non-degraded signal into a plurality of reference signal segments; generate filter coefficients based on each reference signal segment; and filter each reference signal segment with its corresponding generated filter coefficients. The methods, devices, and computer programs may also filter a degraded signal, which includes a delayed signal of the reference signal, with each of the generated filtering coefficients to produce a number of degraded signals equivalent to a number of the plurality of reference signal segments; perform time-wise alignment for each filtered degraded signal with respect to each corresponding filtered reference signal segment; and output a time offset based on the performing. | 12-01-2011 |
20120069888 | Method and Arrangement for Estimating the Quality Degradation of a Processed Signal - An objective quality assessment method for obtaining an improved estimate of a perceptual quality degradation of a processed signal, and an arrangement for executing such a method, is provided, which is executed on a processed signal and an associate reference signal. Both signals are split up into associated frame-pairs after into frames which either all or selected frame-pairs are processed further, by creating a reference residual signal and a processed residual signal for each frame-pair, calculating separate ratios of p-norms on both residual signals, and by calculating and storing a per-frame frame-pair quality estimate on the basis of the ratios of p-norms for each selected frame-pair. An objective per-signal quality estimate that is proportional to the perceptual quality Create degradation is then provided by aggregating the calculated per-frame-pair quality estimates. | 03-22-2012 |

20090174125 | Method and arrangement for heating extended steel products - A method and apparatus for heating extended steel products, such as pipes, tape, or wire products or rods following working such as rolling or extrusion, to a heat treatment temperature, normally to approximately 50 to 900 degrees Celsius. The heating takes place as a result of the product being fed through a burner that has a central through channel into which the product is fed. Fuel and oxidant are supplied through channels that are outside of the central channel and are supplied at such a rate that the combustion of the fuel takes place in front of an outlet opening of the burner head of the burner. | 07-09-2009 |
