A KALMAN FILTERING APPROACH TO GMM PREDICTIVE CODING OF LSFS FOR PACKET LOSS CONDITIONS

Gaussian Mixture Model (GMM)-based vector quantization of Line Spectral Frequencies (LSFs) has gained wide acceptance in speech coding. In predictive coding of LSFs, the GMM approach utilizing Kalman filtering principles to account for quantization noise has been shown to perform better than a baseline GMM Recursive Coder approaches for both clean and packet loss conditions at roughly the same com

The Role of Impaired Interatrial Conduction in Paroxysmal Atrial Fibrillation

Popular Abstract in Swedish Projektet har for avsikt att vardera den elektriska overledningen mellan hjartats formak och hur forsamring av denna overledning bidrar till uppkomsten av attackvis pakommande formaks- flimmer. Studierna har anvant sig av ekg- registreringar fran kroppsytan, registreringar fran hjartats insida, anatomiska dissektionsstudier och djurexperiment. Slutsatser 1. OfiltreratThe aim of this thesis was to evaluate the role of interatrial conduction defects in the genesis of lone paroxysmal atrial fibrillation (AF) using combined approach of non-invasive signal-averaged P-wave ECG, invasive electrophysiological (EP) studies, anatomical studies and animal experiments. Non-filtered signal-averaged P-wave ECG revealed irregularities in orthogonal P-wave morphology and the

Robustness of the Moore-Greitzer Compressor Model's Surge Subsystem with New Dynamic Output Feedback Controllers

This work presents an extension of a design procedure for dynamic output feedback design for systems with nonlinearities satisfying quadratic constraints. In this work we used an axial gas compressor model described by the 3-state Moore-Greitzer compressor model (MG) that has some challenges for output feedback control design (Planovsky and Nikolaev 1990), (Rubanova 2013). The more general constra

Critical action research.

The editors and contributors reflect on ethics and reflexivity in critical management research, and explore the identity of the critical researcher both as an individual and working within collaborative projects. Using contemporary accounts from those engaged in real world fieldwork they outline what critical management is, and explore its relationship to management research. The book discusses t

Classification of bird song syllables using singular vectors of the multitaper spectrogram

Classification of song similarities and differences in one bird species is a subtle problem where the actual answer is more or less unknown. In this paper, the singular vectors when decomposing the multitaper spectrogram are proposed to be used as feature vectors for classification. The advantage is especially for signals consisting of several components which have stochastic variations in the amp
