Analysis of the bounded and unbounded forms of USBM wettability index

open access: yesEnergy Geoscience, 2022
Understanding wettability is important in many processes where porous media and fluids are in contact. The U.S. Bureau of Mines (USBM) is one of the industry standard techniques for measuring wettability.

A stronger bound for the strong chromatic index [PDF]

open access: yesElectronic Notes in Discrete Mathematics, 2015
We prove χ′ s ( G ) ≤ 1.93 Δ( G ) 2 for graphs of sufficiently large maximum degree where χ′

Bounded Conjunctive Queries [PDF]

open access: yes, 2014
A query Q is said to be effectively bounded if for all datasets D, there exists a subset DQ of D such that Q(D) = Q(DQ), and the size of DQ and time for fetching DQ are independent of the size of D. The need for studying such queries is evident, since it

Analytic vector-functions in the unit ball having bounded $\mathbf{L}$-index in joint variables

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2019
In this paper, we consider a class of vector-functions, which are analytic in the unit ball. For this class of functions there is introduced a concept of boundedness of $\mathbf{L}$-index in joint variables, where $\mathbf{L}=(l_1,l_2): \mathbb{B}^2\to ...

Bounds for the distance Estrada index of graphs [PDF]

open access: yesAIP Conference Proceedings, 2015
The D-eigenvalues μ_1,μ_2,...,μ_{n} of a connected graph G are the eigenvalues of its distance matrix. The distance Estrada index of G is defined in [15] as DEE=DEE(G)=Σ_{i=1}^n e^{μ_{i}} In this paper, we give better lower bounds for the distance Estrada index of any connected graph as well as some relations between DEE(G) and the distance energy.

Compactness of minimal hypersurfaces with bounded index [PDF]

open access: yes, 2017
We prove a compactness result for minimal hypersurfaces with bounded index and volume, which can be thought of as an extension of the compactness theorem of Choi–Schoen [4] to higher ...

Analytic in the unit polydisc functions of bounded L-index in direction

open access: yesМатематичні Студії, 2023
The concept of bounded $L$-index in a direction $\mathbf{b}=(b_1,\ldots,b_n)\in\mathbb{C}^n\setminus\{\mathbf{0}\}$ is generalized for a class of analytic functions in the unit polydisc, where $L$ is some continuous function such that for every $z=(z_1 ...

Lower bounds for Estrada Index [PDF]

open access: yesPublications de l'Institut Mathematique, 2008
If G is an (n,m)-graph whose spectrum consists of the numbers ?1, ?2, . . . , ?n, then its Estrada index is EE(G) = ?n i=1 e?i . We establish lower bounds for EE(G) in terms of n and m.

Scope-bounded pushdown languages [PDF]

open access: yes, 2014
We study the formal language theory of multistack push-down automata (Mpa) restricted to computations where a symbol can be popped from a stack S only if it was pushed within a bounded number of contexts of S (scoped Mpa).

Slice Holomorphic Functions in Several Variables with Bounded L-Index in Direction

open access: yesAxioms, 2019
In this paper, for a given direction b ∈ C n \ { 0 } we investigate slice entire functions of several complex variables, i.e., we consider functions which are entire on a complex line { z 0 + t b : t ∈ C } for any z
