Quasi-greedy bases in ℓp (0 < p < 1) are democratic
(Elsevier, 2020)
info:eu-repo/semantics/article,
The list of known Banach spaces whose linear geometry determines the (nonlinear) democracy functions of their quasi-greedy bases to the extent that they end up being democratic, reduces to c0, ℓ2, and all separable L1-spaces. ...
Application of a modeling tool to describe fly ash generation, composition, and melting behavior in a wheat straw fired commercial power plant
(MDPI, 2020)
info:eu-repo/semantics/article,
Ash behavior is a key operational aspect of industrial-scale power generation by means of biomass combustion. In this work, FactSage™ 6.4 software was used to develop and assess three models of wheat straw combustion in a ...
Multigrid solvers for multipoint flux approximations of the Darcy problem on rough quadrilateral grids
(Springer, 2020)
info:eu-repo/semantics/article,
In this work, an efficient blackbox-type multigrid method is proposed for solving multipoint flux approximations of the Darcy problem on logically rectangular grids. The approach is based on a cell-centered multigrid ...
Lipschitz free p-spaces for 0 < p < 1
(SpringerHebrew University Magnes Press, 2020)
info:eu-repo/semantics/article,
This paper initiates the study of the structure of a new class of p-Banach spaces, 0 <p < 1, namely the Lipschitz free p-spaces (alternatively called Arens—Eells p-spaces) Fp(M) over p-metric spaces. We systematically ...
Non-superreflexivity of Garling sequence spaces and applications to the existence of special types of conditional bases
(Instytut Matematyczny, 2020)
info:eu-repo/semantics/article,
We settle in the negative the problem of the superreflexivity of Garling sequence spaces by showing that they contain a complemented subspace isomorphic to a non-superreflexive mixed-norm sequence space. As a by-product, ...
Preparation of Al/Fe-PILC clay catalysts from concentrated precursors: enhanced hydrolysis of pillaring metals and intercalation
(Royal Society of Chemistry, 2020)
info:eu-repo/semantics/article,
The modification of bentonite with Al-Fe species from different concentrated precursors at both stages: (i) the preparation of the (Al/Fe)-mixed pillaring solution and (ii) intercalation itself, was studied at lab scale. ...
Experimental stark widths and shifts of V II spectral lines
(Oxford University Press, 2020)
info:eu-repo/semantics/article,
We have measured the Stark widths and shifts of V II spectral lines in the wavelength range 2000-4200 Å belonging to 75 multiplets. The spectra are emitted by laser-induced plasmas generated from fused glass discs prepared ...
Surface roughness influence on Néel-, crosstie, and Bloch-type charged zigzag magnetic domain walls in nanostructured Fe films
(MDPI, 2020)
info:eu-repo/semantics/article,
Charged magnetic domain walls have been visualized in soft magnetic nanostructured Fe thin films under both static and dynamic conditions. A transition in the core of these zigzagged magnetic walls from Néel-type to ...
Dynamic testing in columns for soil heavy metal removal for a car park SUDS
(Elsevier, 2020)
Artículo / Artikulua,
The increase in urban runoff brought about by a rise in impermeable surfaces has triggered the alteration and pollution of many aquatic systems. The overall goal of this research was to design a ‘Sustainable Urban Drainage ...
Searching for a Debreu’s open gap lemma for semiorders
(Springer, 2020)
info:eu-repo/semantics/bookPart,
In 1956 R. D. Luce introduced the notion of a semiorder to deal with indifference relations in the representation of a preference. During several years the problem of finding a utility function was studied until a ...
