Multilinear Algebra
Appendix A Multilinear Algebra This chapter presents concepts from multilinear algebra based on the basic properties of finite dimensional vector spaces and linear maps. The primary aim of the chapter is to give a concise introduction to alternating tensors which are necessary to define differential forms on manifolds. Many of the stated definitions and propositions can be found in Lee [1], Chaps. 11, 12 and 14. Some definitions and propositions are complemented by short and simple examples. First, in Sect. A.1 dual and bidual vector spaces are discussed. Subsequently, in Sects. A.2–A.4, tensors and alternating tensors together with operations such as the tensor and wedge product are introduced. Lastly, in Sect. A.5, the concepts which are necessary to introduce the wedge product are summarized in eight steps. A.1 The Dual Space Let V be a real vector space of finite dimension dim V = n.Let(e1,...,en) be a basis of V . Then every v ∈ V can be uniquely represented as a linear combination i v = v ei , (A.1) where summation convention over repeated indices is applied. The coefficients vi ∈ R arereferredtoascomponents of the vector v. Throughout the whole chapter, only finite dimensional real vector spaces, typically denoted by V , are treated. When not stated differently, summation convention is applied. Definition A.1 (Dual Space)Thedual space of V is the set of real-valued linear functionals ∗ V := {ω : V → R : ω linear} . (A.2) The elements of the dual space V ∗ are called linear forms on V . © Springer International Publishing Switzerland 2015 123 S.R. -

GYROTROPY AND ANISOTROPY OF ROCKS: SIMILARITIES AND DIFFERENCES The main features of wave propagation in gyrotropic media are compared with wave propagation in anisotropic media. The results of numerical modelling are presented for three typical seismic exploration models. The first two models are azimuthally anisotropic media (of orthorombic symmetry system, group 2m) without and with gyration. The third model is a gyrotropic transversely isotropic medium with a vertical symmetry axis. -

Rotational Particle Separation in Solutions: Micropolar Fluid Theory Approach

We treat the suspension as a micro-polar fluid. The model is validated by comparison with known data of measurement. Within the proposed theory, we prove that sedimentation occurs due to particles’ rotation and rotational diffusion. Keywords: suspensions; micro-polar fluids; yield stress 1. Introduction The classical water-based drilling muds contain only water and clay and their perfor- mances are generally poor. Polymers used in drilling fluids improve stability and cutting removal. Currently, the polymer-based drilling fluids represent 15 to 18% of the total cost (about 1 million) of petroleum well drilling [1]. The reason is that such fluids appear to have load carrying capabilities, or, in other words, a yield stress, associated with the solid-like Citation: Shelukhin, V.

The usefulness of vectors in engineering mathematics results from the fact that many physical quantities-for example velocity of a body, the forces acting on a body, linear and angular momentum of a body, magnetic and electrostatic forces may be represented by vectors. In several respects, the rules of vector calculations are as simple as the rules governing thesystem of real numbers. It is true that any problem that can be solved by the use of vectors can also be treated by non-vectorial methods, but vectol analysis simplifies many calculations considerably. Further more, it is a way of visualizing physical and geometrical quantities and relations between them. For all these reasons, extensive use is made of vector notation in modern engineering literature. -
Cross Product from Wikipedia, the Free Encyclopedia
Cross product From Wikipedia, the free encyclopedia In mathematics and vector calculus, the cross product or vector product (occasionally directed area product to emphasize the geometric significance) is a binary operation on two vectors in three-dimensional space (R3) and is denoted by the symbol ×. Given two linearly independent vectors a and b, the cross product, a × b, is a vector that is perpendicular to both a and b and therefore normal to the plane containing them. It has many applications in mathematics, physics, engineering, and computer programming. It should not be confused with dot product (projection product). If two vectors have the same direction (or have the exact opposite direction from one another, i.e. are not linearly independent) or if either one has zero length, then their cross product is zero. More generally, the magnitude of the product equals the area of a parallelogram with the vectors for sides; in particular, the magnitude of the product of two perpendicular vectors is the product of their lengths. The cross product is anticommutative (i.e. a × b = −(b × a)) and is distributive over addition (i.e. a × (b + c) = a × b + a × c). The space R3 together with the cross product is an algebra over the real numbers, which is neither commutative nor associative, but is a Lie algebra with the cross product being the Lie bracket. Like the dot product, it depends on the metric of Euclidean space, but unlike the dot product, it also depends on a choice of orientation or “handedness“. The product can be generalized in various ways; it can be made independent of orientation by changing the result to pseudovector, or in arbitrary dimensions the exterior product of vectors can be used with a bivector or two-form result. -
Improved Measures for the Shape of a Disordered Polymer to Test a Mean-Field Theory of Collapse Shirin Hadizadeh,† Apichart Linhananta,‡ and Steven S
ARTICLE pubs.acs.org/Macromolecules Improved Measures for the Shape of a Disordered Polymer To Test a Mean-Field Theory of Collapse Shirin Hadizadeh,† Apichart Linhananta,‡ and Steven S. Plotkin*,† †Department of Physics and Astronomy, University of British Columbia, Vancouver, Canada ‡Physics Department, Lakehead University, Thunder Bay, Ontario, Canada bS Supporting Information ABSTRACT: We have generated off-lattice self-avoiding ran- dom walks (SAWs) by both Lal’s pivot algorithm and by discontinuous molecular dynamics (DMD) simulations. We chose several volume measures to analyze and compare the shapes characterizing ensembles of SAWs. These included the Flory volume defined through the end-to-end distance, the volume corresponding to the radius of gyration of the polymer, the volume of a sphere drawn from the center of polymer mass that encloses or embeds all the monomers in the polymer, the corresponding ellipsoid describing the radius of gyration tensor, the volume of the smallest Cartesian box oriented in a fixed “lab” frame which encloses all polymer monomers, and the volume of the smallest box oriented along the principal axes of the radius of gyration tensor that encloses all polymer monomers. The tensor ellipsoid and principal box correlate well with each other but not with the other measures. There is a substantial amount of polymer that is excluded from the radius of gyration sphere or ellipsoid (approximately 42% and 44% respectively on average), which casts doubt on the utility of these measures in quantitatively characterizing the volume spanned by a polymer configuration. The principal box volume led to the most well-defined length distribution for the SAW in terms of the ratio of standard deviation to the mean, while the end-to-end distribution was the most broadly distributed. -

Vector Calculus for Engineers Lecture Notes for Jeffrey R.

Preface View the promotional video on YouTube These are the lecture notes for my online Coursera course, Vector Calculus for Engineers. Students who take this course are expected to already know single-variable differential and integral calculus to the level of an introductory college calculus course. Students should also be familiar with matrices, and be able to compute a three-by-three determinant. I have divided these notes into chapters called Lectures, with each Lecture corresponding to a video on Coursera. I have also uploaded all my Coursera videos to YouTube, and links are placed at the top of each Lecture. There are some problems at the end of each lecture chapter. These problems are designed to exemplify the main ideas of the lecture. Students taking a formal university course in multivariable calculus will usually be assigned many more problems, some of them quite difficult, but here I follow the philosophy that less is more. I give enough problems for students to solidify their understanding of the material, but not so many that students feel overwhelmed. I do encourage students to attempt the given problems, but, if they get stuck, full solutions can be found in the Appendix.
