Two of the most prominent trends in world affairs over the past decade--the projection of American power abroad and high energy prices--have made for some strange bedfellows. Flush with oil revenues, autocratic governments in Venezuela, Iran, and Russia have tried to counter U.S. influence not only in Latin America but around the world. In Axis of Unity, Sean Goforth explores the motives and contributions of each nation to the partnership. Venezuela and Iran's self-declared "axis of unity" in 2007 forms the alliance's base. Caracas and Tehran support each other's attempt at regional domination through a series of illicit ties. Russia provides the alliance's superstructure, shielding Iran from Western ire and selling billions of dollars worth of sophisticated arms to Caracas and Tehran. The regional repercussions of this alliance, Goforth asserts, are far-reaching. Venezuela and Iran utilize various forces--the Revolutionary Armed Forces of Colombia (FARC), Hamas, Hezbollah, and the Quds Force--to attack regional competitors, chiefly Colombia and Israel. The key to dismantling the threat, Goforth demonstrates, is a flexible foreign policy. America should take a bold stand against Russia in Eastern Europe, where leaders seek strong U.S. backing, and adopt a long-term plan for reducing the influence of Venezuela and Iran in Latin America and the Middle East. Axis of Unity will be of great value to readers interested in international affairs, U.S. foreign policy, security studies, and the geopolitics of rising powers.

Minerals and rocks form the foundation of geologic studies. This new textbook has been written to address the needs of students at the increasing number of universities that have compressed separate mineralogy and petrology courses into a one- or two-semester Earth materials course. Key features of this book include: equal coverage of mineralogy, sedimentary petrology, igneous petrology and metamorphic petrology; copious field examples and regional relationships with graphics that illustrate the concepts discussed; numerous case studies to show the uses of earth materials as resources and their fundamental role in our lives and the global economy, and their relation to natural and human-induced hazards; the integration of earth materials into a cohesive process-based earth systems framework; two color thoughout with 48 pages of four color. Readership: students taking an earth materials, or combined mineralogy and petrology course in an earth science degree program. It will also be useful for environmental scientists, engineering geologists, and physical geographers who need to learn about minerals, rocks, soil and water in a comprehensive framework.

Virtual reality is quickly becoming the next medium to communicate your ideas. Once siloed in make-believe world of science fiction, virtual reality can now touch any aspect of your life. This book shows you how to create original virtual reality content using the Unity game engine and the Virtual Reality Tool Kit. By the end of the book you'll be creating your own virtual reality experience using the fundamental building blocks within. You'll start by reviewing spatial computing, an emerging field that encompasses self-driving cars to space exploration. You'll also create your own virtual reality environments for use on headsets such as those from Oculus and HTC. Using the Unity3D game engine and the Virtual Reality Toolkit on a computer or laptop, you will walk through the fundamentals of virtual reality with as little code as possible. That is the beauty of Unity and the Virtual Reality Toolkit. You will discover how to use buttons in a virtual space, gaze-tracking for user input, and physics for enabling interaction between a human and a virtual space. From game design to education to healthcare to human resources, virtual reality offers new and creative ways to engage users, students, patients, customers, and more. Not a coding book, Virtual Reality with VRTK4 shows that you don't need to be a computer or graphics whiz to begin creating your own virtual reality experiences. What You'll Learn Grasp Virtual Reality Toolkit and its interaction with Unity3DExplore the fundamental science of virtual realityReview the inner workings of Unity3D and its integration with VRTKUnderstand the big picture of C# coding in Unity3DIncorporate head and hand movement into virtual experiences Who This Book Is For Creative professionals or students who are familiar with computer design programs and want to begin prototyping their own original virtual reality work as quickly as possible.

"Quaternions are members of a noncommutative division algebra first invented by William Rowan Hamilton. They form an interesting algebra where each object contains 4 scalar variables, instead of Euler angles, which is useful to overcome the gimbal lock phenomenon when treating the rotation of objects. This book is about the mathematical basics and applications of quaternions. The first four chapters mainly concerns the mathematical theories, while the latter three chapters are related with three application aspects. It is expected to provide useful clues for researchers and engineers in the related area. In detail, this book is organized as follows: In Chapter 1, mathematical basics including the quaternion algebra and operations with quaternions, as well as the relationships of quaternions with other mathematical parameters and representations are demonstrated. In Chapter 2, how quaternions are formulated in Clifford Algebra, how it is used in explaining rotation group in symplectic vector space and parallel transformation in holonomic dynamics are presented. In Chapter 3, the wave equation for a spin 3/2 particle, described by 16-component vector-bispinor, is investigated in spherical coordinates. In Chapter 4, hyperbolic Lobachevsky and spherical Riemann models, parameterized coordinates with spherical and cylindric symmetry are studied. In Chapter 5, ship hydrodynamics with allowance of trim and sinkage is investigated and validated with experiments. In Chapter 6, the ballast flying phenomenon based on Discrete Discontinuous Analysis is presented. In Chapter 7, a numerical study is proposed to analyze the effect of the caisson sliding subjected to a hydrodynamic loading in the stability of the rear side of the rubble mound breakwater"--
