to prospect mineral deposits at regional scale, recognition and classification of hydrothermal alteration zones using remote sensing data is a popular strategy. due to the large number of spectral bands, classification of the hyperspectral data may be negatively affected by the hughes phenomenon. a practical way to handle the hughes problem is preparing a lot of training samples until the size ...

In supervised classification, each pixel of the image is labeled as representing a particular ground cover or class, taking information provided by the training samples, since the parameters of the classifier are estimated from the training samples. This training can be established using maps, site visits, or aerial photography. As the number of spectral bands or dimensions increases, the separ...

Pre-metaphase stretch is a term first coined by the preeminent cell biologist Sally Hughes-Schrader in 1950 to describe an elongation of prometaphase chromosomes observed primary spermatocytes phasmid insects and praying mantids. Research from many groups since Hughes-Schrader’s initial observation has revealed reasons for both how why might elongate prior metaphase. In this review, we findings...

To prospect mineral deposits at regional scale, recognition and classification of hydrothermal alteration zones using remote sensing data is a popular strategy. Due to the large number of spectral bands, classification of the hyperspectral data may be negatively affected by the Hughes phenomenon. A practical way to handle the Hughes problem is preparing a lot of training samples until the size ...

This paper offers an analysis of the representation of Aboriginal mothers in Jane Harrison’s play, Stolen. It argues that the Aboriginal mother characters in Stolen endeavour to engage in maternal practices even after their children are taken from them. The act of a non-Aboriginal person speaking about Aboriginal representation is acknowledged as problematic. Further, this paper proposes that i...

The presented work deals with the problem of remote sensing data separation and fusion. Multispectral images are acquired from different bands. The collected radiances are the results of many reflections due to the land heterogeneity and the atmosphere. The mixture phenomenon is therefore nonlinear. This work aims to find an adequate nonlinear separation model based on Bayesian inferences. Sour...

We would like to provide evidence for the fact that zeros of L-functions seem to behave statistically as eigenvalues of random matrices of large rank throughout the instance of Hecke L-functions. First, we remind you of Iwaniec-Luo-Sarnak’s results on one-level densities for low-lying zeros of Hecke L-functions (see [5]) and Katz-Sarnak’s results on one-level densities for eigenvalues of orthog...

To a generation of philosophers, modal logic was a field with ties to some of the most active areas of research and Hughes and Cresswell was the authoritative text and reference to that field. 'Hughes and Cresswell,' of course, referred to the authors' An Introduction to Modal Logic, published by Methuen in 1968 and reprinted as a University Paperback in 1972. Supposing no prior logic, An Intro...

In remote sensing, the number of training samples is often limited. For hyperspectral data, it becomes more difficult to obtain accurate estimates of class statistics because of the small ratio of the training sample size to dimensionality. Generally speaking, classification performance depends on four factors: class separability, the training sample size, dimensionality, and classifier type (o...
