Region-based classification of PolSAR data using radial basis kernel functions with stochastic distances
(2018-06-05)
Region-based classification of PolSAR data can be effectively performed by seeking for the assignment that minimizes a distance between prototypes and segments. Silva et al. [“Classification of segments in PolSAR imagery ...
Unsupervised distance learning by reciprocal kNN distance for image retrieval
(2014-01-01)
This paper presents a novel unsupervised learning approach that takes into account the intrinsic dataset structure, which is represented in terms of the reciprocal neighborhood references found in different ranked lists. ...
THE DISTANCES TO 5 TYPE-II SUPERNOVAE USING THE EXPANDING PHOTOSPHERE METHOD, AND THE VALUE OF HO
(UNIV CHICAGO PRESS, 1994-09-01)
We have used observations gathered at CTIO to measure distances by the expanding photosphere method (EPM) to five Type II supernovae. These supernovae lie at redshifts from cz = 1100 km s-1 to cz - 5500 km s-1, and increase ...
Online distance mathematics education in Brazil: Research, practice and policy
(2010-01-22)
In this article, we address online distance mathematics education research and practice in Brazil, which are relative newcomers to the educational scene. We present the national context of education in Brazil, highlighting ...

Dispersal traits drive the phylogenetic distance decay of similarity in Neotropical stream metacommunities
(2015-11-01)
Aim: The drivers of phylogenetic beta diversity include both local processes (e.g. environmental filtering) and regional processes (e.g. dispersal limitation). The role of environmental filtering can be investigated more ...
A New Family of Distance Functions for Perceptual Similarity Retrieval of Medical Images
(SPRINGER, 2009)
A long-standing challenge of content-based image retrieval (CBIR) systems is the definition of a suitable distance function to measure the similarity between images in an application context which complies with the human ...
A STUDY ON THE POSSIBLE ONGOING DROPOUT CAUSES OF BACHELOR IN EDUCATION THE DISTANCE
(Unesp-faculdade Ciencias & Letras, 2016-09-01)
This study aimed to investigate which were the possible causes that influenced the distance learning courses dropouts from the students'perceptions. For this, it was carried out a descriptive exploratory study using a ...
Distance technologies in action: E-learning in exile (the experience of Donetsk National University, Ukraine)

Colouring exact distance graphs of chordal graphs
(Elsevier, 2020)
For a graph G = (V, E) and positive integer p, the exact distance-p graph G([hp]) is the graph with vertex set V and with an edge between vertices x and y if and only if x and y have distance p. Recently, there has been ...
