In this paper we present a distributed algorithm for MVDR beamforming which is based on message passing. The message-passing algorithm performs generalized linear-coordinate descent (GLiCD) operations to exchange messages between neighboring microphone nodes, which converges increasingly fast as the noise correlation matrix becomes more and more diagonal. The algorithm makes use of a trade-off ...

Many objects in a scene are composed of more than one block. So when the object moves, a set of blocks, move together. Most blocks are either completely in the background or are part of the moving object and in most cases (except boundary blocks) neighboring blocks move together. Given that a majority of the neighbors of a block move in a certain direction, it is reasonable to assume that the b...

We investigated the way in which binocular coordination in reading is affected by the spatial structure of text. Vergence eye movements were measured (EyeLink II) in 32 observers while they read 120 single German sentences (Potsdam Sentence Corpus) silently for comprehension. The similarity in shape between the neighboring strokes of component letters, as measured by the first peak in the horiz...

The definition of objective and effective thresholds in MRI of human brain function is a crucial step in the analysis of paradigm-related activations. This paper introduces a user-independent and robust procedure that calculates statistical parametric maps based on correlation coefficients. Thresholds are introduced as p values and defined with respect to the physiologic noise distribution of t...

In this paper we present an efficient error concealment (EC) method for the fine granularity scalable (FGS) video transmission. The proposed EC method exploits both the temporal and spatial correlations in an FGS encoded bitstream. In our scheme, the temporal redundancy is used to improve the quality of contaminated regions, and the intensity of the temporal correlation in contaminated regions ...

In LTE system, due to resource scheduling on the same frequency, the target cell and neighboring cells must take measures to suppress the co-channel interference to improve the system performance. The time delay spread and correlation bandwidth are treated as fixed value when the correlation matrix is calculated in the interference rejection combining algorithm, which degrades the performance o...

The “spectral correlation function” analysis we introduce in this paper is a new tool for analyzing spectral-line data cubes. Our initial tests, carried out on a suite of observed and simulated data cubes, indicate that the spectral correlation function [SCF] is likely to be a more discriminating statistic than other statistical methods normally applied. The SCF is a measure of similarity betwe...

The relative stereochemistry of tris-heteroleptic ruthenium complexes [Ru(pp)(pp')(pp'')](PF(6))(2), where pp = 1,10-phenanthroline-4-carboxamide, pp' = 5,6-dimethyl-1,10-phenanthroline, and pp'' = 7,8-dimethyl dipyrido[3,2-a:2',3'-c]phenazine, was studied using NMR spectroscopy. The (1)H and (13)C spectra were assigned by using double-quantum-filtered correlation spectroscopy (DQF-COSY), heter...
