Fractional Variation of Hölderian Functions [PDF]

Fractional Calculus and Applied Analysis, 2015
The paper demonstrates the basic properties of the local fractional variation operators (termed fractal variation operators). The action of the operators is demonstrated for local characterization of Holderian functions. In particular, it is established that a class of such functions exhibits singular behavior under the action of fractal variation ...

Genetic analysis of environmental variation [PDF]

, 2010
Environmental variation (V-E) in a quantitative trait - variation in phenotype that cannot be explained by genetic variation or identifiable genetic differences - can be regarded as being under some degree of genetic control. Such variation may be either

FRACTAL VECTOR MEASURES IN THE CASE OF AN UNCOUNTABLE ITERATED FUNCTION SYSTEM [PDF]

Romanian Journal of Mathematics and Computer Science, 2015
In this paper we obtain an extension of the concept of Hutchinson measure (which is the unique fixed point of a contraction on the set of normalized Borel measures on a compact metric space) related to an iterated function system.

Bone Dielectric Property Variation as a Function of Mineralization at Microwave Frequencies

International Journal of Biomedical Imaging, 2012
A critical need exists for new imaging tools to more accurately characterize bone quality beyond the conventional modalities of dual energy X-ray absorptiometry (DXA), ultrasound speed of sound, and broadband attenuation measurements.

EEMD-Based Steady-State Indexes and Their Applications to Condition Monitoring and Fault Diagnosis of Railway Axle Bearings

Sensors, 2018
Railway axle bearings are one of the most important components used in vehicles and their failures probably result in unexpected accidents and economic losses.

A role for gene duplication and natural variation of gene expression in the evolution of metabolism. [PDF]

PLoS ONE, 2008
Most eukaryotic genomes have undergone whole genome duplications during their evolutionary history. Recent studies have shown that the function of these duplicated genes can diverge from the ancestral gene via neo- or sub-functionalization within single ...

Variation in coordination of a discrete multiarticular action as a function of skill level

, 2007
The authors investigated coordination modes that emerged as a function of the interaction between skill level and task constraints in a multiarticular kicking action.

Regional variation in the pronunciation of /s/ in the Dutch language area [PDF]

, 2019
This paper reports on an explorative sociophonetic study of the phoneme /s/ in the Dutch language area. Our aim is to investigate the regional variation in the realisation of this phoneme, and to test experimentally the observation of Collins & Mees ...

ON FIRST AND SECOND PHI-VARIATION IN THE SENSE OF SCHRAMM-RIESZ // SOBRE LA PRIMERA Y SEGUNDA PHI-VARIACION EN EL SENTIDO DE SCHRAMM-RIESZ

Publicaciones en Ciencias y Tecnología, 2013
In this paper we present a generalization of the concepts of rst and second -variation (where is a certain sequence of positive convex function de ned on [0;+1)), in the sense of Schramm-Riesz for normed space valued functions de ned on an interval [a; b]
