  • This book is intended for graduate students, researchers, and reservoir engineers who want to understand the mathematical description of the chromatographic mechanisms that are the basis for gas injection processes for enhanced oil recovery. Readers familiar with the calculus of partial derivatives and properties of matrices (including eigenvalues and eigenvectors) should have no trouble following the mathematical development of the material presented.

  • In this paper, some new results on the preservation of many good cryptographic properties of MDS matrices under direct exponent transformation are presented. These good cryptographic properties include MDS, involutory, symmetric, recursive (exponent of a companion matrix ), the number of 1 0 s and distinct elements in a matrix, circulant and circulant-like

  • Let A be an n × n matrix, whose entries are independent copies of a centered random variable satisfying the subgaussian tail estimate. We prove that the operator norm of A−1 does not exceed Cn3/2 with probability close to 1. 1. Introduction Let A be an n × n matrix, whose entries are independent, identically distributed random variables. The spectral properties of such matrices, in particular invertibility, have been extensively studied (see, e.g. [M] and the survey [DS]).

  • This study investigates the technique to overcome these challenges without the treatment and surface modification of natural additive fillers. The obtained experimental results showed that using maleic anhydride grafted ethylene vinyl acetate copolymer (EVA-g-MA) with 1.16 wt.% of MA could enhance the adhesion and interaction of bamboo flour (BF) with EVA and polypropylene (PP) matrices.

  • We are concerned about various strongly clean properties of a kind of matrix subrings L(s)(R) over a local ring R. Let R be a local ring, and let s ∈ C(R). We prove that A ∈ L(s)(R) is strongly clean if and only if A or I2−A is invertible, or A is similar to a diagonal matrix in L(s)(R).

  • CLASSICAL GEOMETRY — LECTURE NOTES DANNY CALEGARI 1. A CRASH COURSE IN GROUP THEORY A group is an algebraic object which formalizes the mathematical notion which expresses the intuitive idea of symmetry. We start with an abstract definition. Definition 1.1. A group is a set G and an operation m : G × G → G called multiplication with the following properties: (1) m is associative. That is, for any a, b, c ∈ G, m(a, m(b, c)) = m(m(a, b), c) and the product can be written unambiguously as abc. (2) There is a unique element e ∈ G called the...

  • This study focuses on linear dynamical systems whose dynamics are affine in the control input. Such dynamics are extensively considered to be rewritten into a canonical form, namely the passive port-Hamiltonian representation in order to further explore some structural properties such as interconnection and damping matrices, Hamiltonian storage function and dissipation term.

  • The Geometry Package For example, combinations of elements, such as scale and rotation, can be applied at once, and matrices can even be used to achieve effects that are otherwise not possible with individual properties, such as skewing. You can also use matrices for more advanced operations such as determining where a point ends up after an object has been transformed. In other words, the point (10, 10) near the upper-left corner of a rectangle will not be at point (10, 10) after a 90-degree rotation. The Matrix class can tell you the new location to which that point has moved,...

  • Cartilage provides our joints with load support and lubrication for decades of continuous use with minimal friction or damage. These unusual bearing properties are in fact due to a biphasic tissue structure (containing both fluid and solid matrices) and the pressurization of interstitial fluid during dynamic deformations.
