Speech recognition in multi-channel environments requires target speaker localization, multi-channel signal enhancement and robust speech recognition. We here propose a system that addresses these problems: Localization is performed with a recently introduced probabilistic localization method that is based on support-vector machine learning of GCC-PHAT weights and that estimates a spatial sourc...

Decentralized cooperative localization (DCL) is a promising method to determine accurate multirobot poses (i.e., positions and orientations) for robot teams operating in an environment without absolute navigation information. Existing DCL methods often use fixed measurement noise covariance matrices pose estimation; however, their performance degrades when the are time-varying. To address this ...

  The distribution and localization of acid and neutral mucins in various cells lining the olfactory epithelium of Cyprinus carpio have been studied histochemically by employing the PAS-AB technique. Variations in the localization of protein in different cells lining the olfactory epithelium have been correlated with the functional significance of the region concerned. Intense localization of t...

Ensemble Kalman filters are developed for turbulent dynamical systems where the forecast model does not resolve all the active scales of motion. These filters are based on the assumption that a coarse-resolution model is intended to predict the large-scale part of the true dynamics; since observations invariably include contributions from both the resolved large scales and the unresolved small ...

In recent years there has been a growing interest in position location in indoor venues. As more applications requiring indoor localization are emerging in the market, the demand for accurate and reliable localization increases. Unfortunately, the accuracy of available techniques is limited, and a dense and expensive deployment is required. The problem of accurate indoor localization is challen...

shoulder movements are a complex motor act, controlled by many muscles attached to thescapula and the vertebral column. these muscles are innervating by motoneurons (mns) located in theventral horn of the spinal cord. motoneurons of the ventral horn are arranged such that several groups ofmns can be distinguished in a transverse section through the spinal cord. the anatomical or functionalimpli...

the aim of this critical appraisal and hazards of surface electromyography (semg) is to enhance the data acquisition quality in voluntary but complex movements, sport and exercise in particular. the methodological and technical registration strategies deal with telemetry and online data acquisition, the placement of the detection electrodes and the choice of the most adequate normalization mode...

This letter deals with the problem of clutter edge detection and localization in training data. To this end, is formulated as a binary hypothesis test assuming that ranks covariance matrix are known, adaptive architectures designed based on generalized likelihood ratio to decide whether data within sliding window contains homogeneous set or two heterogeneous subsets. In design stage, we utilize...

Abstract This paper presents a method to estimate the covariances of inputs in factor-graph formulation for localization under non-line-of-sight conditions. A general solution based on covariance estimation and M-estimators linear regression problems, is presented that shown give unbiased estimators multiple variances are robust against outliers. An iteratively re-weighted least squares algorit...
