Normal -Fitting classes [PDF]

open access: yesProceedings of the Edinburgh Mathematical Society, 1992
The authors together with M. J. Karbe [Ill. J. Math.33 (1989) 333–359] have considered Fitting classesof-groups and, under some rather strong restrictions, obtained an existence and conjugacy theorem for-injectors. Results of Menegazzo and Newell show that these restrictions are, in fact, necessary.The Fitting classisnormalif, for eachis the unique ...

ETAS: An R Package for Fitting the Space-Time ETAS Model to Earthquake Data

open access: yesJournal of Statistical Software, 2019
The epidemic-type aftershock sequence (ETAS) model is the most widely used statistical model to describe earthquake catalogs. ETAS is an R package for fitting the space-time ETAS model to an earthquake catalog using the stochastic declustering approach ...

A progressive decay Mixup data augmentation for long-tailed image classification [PDF]

open access: yesPeerJ Computer Science
Image classification with long-tailed distribution (i.e., a few classes occupy most of the training samples, while most classes have only a small number of representations) is a challenging visual task at present.

La construction d’une exception territoriale : L’éducation à la nature par les classes de mer finistériennes

open access: yesM@ppemonde, 2023
Invented in 1964 in Finistère (Brittany), sea classes are still very popular locally. Goying beyond the educational sphere, this program has received support from local tourism and political actors.

Performance comparison of model selection criteria by generated experimental data

open access: yesITM Web of Conferences, 2018
In Bioinformatics and other areas the model selection is a process of choosing a model from set of candidate models of different classes which will provide the best balance between goodness of fitting of the data and complexity of the model.

Relative influence of genetics and shared environment on child mental health symptoms depends on comorbidity. [PDF]

open access: yesPLoS ONE, 2014
Comorbidity among childhood mental health symptoms is common in clinical and community samples and should be accounted for when investigating etiology.

ANALYZING THE SHAPE CHARACTERISTICS OF LAND USE CLASSES IN REMOTE SENSING IMAGERY [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
Shape is an important aspect of spatial attributes of land use segments in remotely sensed imagery, but it is still rarely used as a component in land use classification or image-based land use analysis.

On the minimal definitions of quasilocal Fitting classes [PDF]

open access: yes, 2022
Throughout this paper, all groups are finite. In the theory of classes of finite group, the idea of localization is fundamental. The main goal of this work is to generalize the notion of o-local Fitting classes and to study the structural properties of ...

On the characterization of Hall-closed Fitting classes [PDF]

open access: yes, 2022
The paper considers only finite groups. An actual problem in studying the structure of classes of groups is the characterisation of Fitting classes that are closed under taking Hall subgroups. The purpose of the paper is the study of Hell-closed Fitting

A note on fitting classes

open access: yesMathematische Zeitschrift, 1974
A subgroup V of G is called an j in jector of G if Vc~ N is F-maximal in N (that is, Vn N is a maximal ~-subgroup of N) for each subnormal subgroup N of G. It is known that the ~-injectors of a group G form a conjugacy class of subgroups 1,2]. If ~-injectors are always normal then ~ is called a normal Fitting class.
