Approximating Real Functions Which Possess n-th Derivatives of Bounded Variation and Applications [PDF]
, 2007 The main aim of this paper is to provide an approximation for the function f which possesses continuous derivatives up to the order n−1 (n ≥ 1) and has the n−th derivative of bounded variation, in terms of the chord that connects its end points A = (a,

Variation of Matric Suction as a Function of Gypseous Soil Dry Density [PDF]
Engineering and Technology Journal, 2020 Gypseous soil is one of the most problematic types of collapsible soils which is affected by many geotechnical factors. The most important factors are the effect of loading and wetting and their relation to soil density, especially when the soil at ...

Variational Convexity of Functions and Variational Sufficiency in Optimization
SIAM Journal on Optimization, 2023 The paper is devoted to the study, characterizations, and applications of variational convexity of functions, the property that has been recently introduced by Rockafellar together with its strong counterpart. First we show that these variational properties of an extended-real-valued function are equivalent to, respectively, the conventional (local ...

Integral representation of functions of bounded second Φ-variation in the sense of Schramm [PDF]
Opuscula Mathematica, 2012 In this article we introduce the concept of second \(\Phi\)-variation in the sense of Schramm for normed-space valued functions defined on an interval \([a,b] \subset \mathbb{R}\). To that end we combine the notion of second variation due to de la Vallée

Phonation Variation as a Function of Checked Syllables and Prosodic Boundaries
Languages, 2022 The phonation variation in Shanghainese is influenced by both phonemic phonation contrast and global prosodic context. This study investigated the phonetic realization of checked and unchecked syllables at four different prosodic positions (sandhi-medial,

Variational Properties of Value Functions [PDF]
SIAM Journal on Optimization, 2013 Regularization plays a key role in a variety of optimization formulations of inverse problems. A recurring theme in regularization approaches is the selection of regularization parameters, and their effect on the solution and on the optimal value of the optimization problem.

Models to estimate river temperature. Example for Danube, at Oltenița in the context of climate change and anthropic impact [PDF]
E3S Web of Conferences, 2021 Daily variation of Danube River temperature measured at Oltenitț gauging station over 9 years (2008-2016) was analysed in comparison with the air temperature measured by satellite in the same location between 1979-2020. Air temperature shows a nearly 2°C
