We study a two-action, two-state pure persuasion game in which the receiver has non-rational expectations. The sender can add ambiguity to his message by pooling it with other messages. This be likened selective redaction of original message. knows sender’s strategy but not strategy, and uses only former draw inferences from redacted characterize highest probability attainable under these condi...

This contribution aims to offer new insights into the context of manuscript Paris, Bibliothèque nationale de France, fr. 1822. Keith Busby has recently ascribed this miscellany Old French moral texts (sole witness Jofroi Waterford’s translations) Irish city Waterford. The paper discusses hypothesis, focusing on codicological and historical aspects manuscripts. Moreover, article presents my rese...

Normative Acts are important legislative and regulatory documents made by different governmental organs. Every year, a huge amount of information is provided in Normative Acts by these organs without control, i.e., there is no effective way to verify redundancies, inconsistencies, crossimpact and ambiguities. In this paper, we propose a domain ontology for Normative Acts based on official docum...

‘Speckle’ noise refers to the granular patterns that occur in ultrasound images due to wave interference. Speckle removal can greatly improve the visibility of the underlying structures in an ultrasound image and enhance subsequent post-processing. We present a novel framework for speckle removal based on low-rank non-local filtering. Our approach works by first computing a guidance image that ...

PURPOSE Speckle suppression in ultrasound (US) images of various anatomic structures via a novel speckle noise reduction algorithm. METHODS The proposed algorithm employs an enhanced fuzzy c-means (EFCM) clustering and multiresolution wavelet analysis to distinguish edges from speckle noise in US images. The edge detection procedure involves a coarse-to-fine strategy with spatial and intersca...

Speckle-fringe quality can be improved by averaging many statistically independent interferograms together, which are generated by shifting the object's illumination angle. A technique applicable to double-exposure speckle interferograms obtained from processing two speckle patterns is described. It utilizes a computer-controlled stepping motor to tilt the object illumination, which is repeatab...

We propose a method for increasing the resolution of an aperture limited optical system by illuminating the input with a speckle pattern. The high resolution of the projected speckle pattern demodulates the high frequencies of the sample and permits its passage through the system aperture. A decoding provides the superresolved image. The speckle pattern can be generated in a simple manner in co...

Surface speckle pattern intensity distribution resulting from laser light scattering from a rough surface contains various information about the surface geometrical and physical properties. A surface roughness measurement technique based on the texture analysis of surface speckle pattern texture images is put forward. In the surface roughness measurement technique, the speckle pattern texture i...

The ultimate objective of laser speckle flowmetry (and a host of specific implementations such as laser speckle contrast analysis, LASCA or LSCA; laser speckle spatial contrast analysis, LSSCA; laser speckle temporal contrast analysis, LSTCA; etc.) is to infer flow velocity from the observed speckle contrast. Despite numerous demonstrations over the past 25 years of such a qualitative relations...
