Derivatives in noncommutative calculus and deformation property of quantum algebras

Dimitri Gurevich, Pavel Saponov

The aim of the paper is twofold. First, we introduce analogs of (partial) derivatives on certain noncommutative algebras, including some enveloping algebras and their “braided counterparts” — the so-called modified Reflection Equation algebras. With the use of the mentioned derivatives we construct…

Predictive models of the energy consumption in intelligent buildings

M Fratu, Jean-Paul Becar, Jean-Charles Canonne

In this work we present a novel approach to energy saving in buildings through the identification of the relevant parameters and the application of Soft Computing techniques to generate predictive models of energy consumption in buildings. To verify the feasibility of this proposal, we apply our…

Minimal translation hypersurfaces in E4

Marilena Moruz, Marian Ioan Munteanu

In this paper we consider hypersurfaces in the Euclidean space E4 defined as the sum of a curve and a surface whose mean curvature vanishes. We call them minimal translation hypersurfaces in E4 and give a classification of these hypersurfaces.

Residual-based a posteriori estimators for the potential formulations of electrostatic and time-harmonic eddy current problems with voltage or current excitation

Chao Chen, Emmanuel Creusé, Serge Nicaise, Zuqi Tang

In this paper, we present some residual-based a posteriori estimators for the potential formulations of electrostatic and time-harmonic eddy current problems with voltage or current excitation. The reliability of the proposed estimators is proved and some numerical experiments are carried out to…

Electrical, dielectric and photocatalytic properties of Fe-doped ZnO nanomaterials synthesized by sol gel method

Yacine Cherifi, Ahcène Chaouchi, Yannick Lorgouilloux, Mohamed Rguiti, Abdelaziz Kadri, Christian Courtois

Fe-doped ZnO nanoparticles were synthesized by sol gel technique. Fine-scale and single phase hexagonal wurtzite structure in all samples were confirmed by SEM and XRD, respectively. The band gap energy depends on the amount of Fe and was found to be in the range of 3.11–2.53 eV. The electric and…

Residual-based a posteriori error estimates for a nonconforming finite element discretization of the Stokes–Darcy coupled problem: isotropic discretization

Serge Nicaise, Bernardin Ahounou, Wilfrid Koffi Houedanou

In this paper we develop an a posteriori error analysis of a nonconforming mixed finite element method for the coupling of fluid flow with porous media flow. The approach utilizes the same nonconforming Crouzeix–Raviart element discretization on the entire domain (Rui and Zhang, Comput Methods Appl…
