In this report various aspects of Finite Temperature and Density Quantum Field Theory are discussed. The main point being the calculation of Green’s functions in this context, in which pertubation theory is used. The motivation for calculating Green’s functions comes from their wide application in modern Physics. The techniques that are presented here are used in such areas as condensed matter,...

abstract objective: to present the changes in projected thoracic hypokyphosis and the behavior of lumbar lordosis within and below the fusion and to compare these changes between the harrington rod (hr) and posterior multisegmented hook instrumentation. methods: 178 patients with idiopathic scoliosis, who had undergone posterior spinal fusion with harrington technique (106 patients) or multiseg...

Speaker verification from talking a few words of sentences has many applications. Many methods as DTW, HMM, VQ and MQ can be used for speaker verification. We applied MQ for its precise, reliable and robust performance with computational simplicity. We also used pitch frequency and log gain contour for further improvement of the system performance.

various authors have considered the zero-rest-mass equation and the contour integral representation of its solutions. ferber generalized these equations to supertwistor spaces with 2n odd components so that with n=o we get the standard ungraded twistors of penrose. in this paper we use the batchelor theorem toconstruct the natural super twistor space with coarse topology with underlying standar...

The current study investigates the relationship between perceived syllable prominence and the F0 contour in terms of the parameters of a linguistically motivated model of German intonation based on the Fujisaki formula. A subcorpus of the Bonn Prosodic Database was analyzed using the F0 model, and normalized log syllable durations were calculated. Analysis shows that, for accented syllables, pr...

In this paper, we present a new method and its preliminary results within the context of pattern analysis and recognition. This method is based on the multiscale analysis of a curve and deals with the contour of planar objects. Our method uses a low-pass Gaussian kernel to gradually smooth the contour by decreasing the filter bandwidth. Applying gain control to the smoothed contour stretches it...
