Free Download Handbook of Calculus of Variations for Absolute Beginners English | 2025 | ISBN: 3031871634 | 617 Pages | PDF EPUB (True) | 50 MB The book aims at endowing any student with a survival toolkit to start safely diving into the realm of Calculus of Variations. In summary, the latter is a part of mathematical analysis devoted to minimization/maximization problems. A great effort has been made to present the themes and methods considered in the book in the simplest possible way: the reader will not find here general statements or proofs based on general abstract theories. In contrast, the main focus of the book is on introducing some key concepts "from scratch", by means of simple and meaningful explicit examples (including for instance, the classical isoperimetric and brachistocrone problems, as well as the boundary value problem for harmonic functions). In particular, the book is mainly (but not exclusively) designed to smoothly introduce the reader to the so-called Direct Method of the Calculus of Variations, which is a central concept in the field. Accordingly, a good part of the book is devoted to discussing spaces of weakly differentiable functions (i.e., Sobolev and Lipschitz functions), which are essential tools of the Direct Method.  Free Download Andrew J. Elliot, "Handbook of Approach and Avoidance Motivation" English | ISBN: 0805860193 | 2008 | 682 pages | EPUB | 14 MB Of the many conceptual distinctions present in psychology today, the approach-avoidance distinction stands out as one of, if not the, most fundamental and basic. The distinction between approach and avoidance motivation has a venerable history, not only within but beyond scientific psychology, and the deep utility of this distinction is clearly evident across theoretical traditions, disciplines, and content areas. This volume is designed to illustrate and highlight the central importance of this distinction, to serve as a one-stop resource for scholars working in this area, and to facilitate integration among researchers and theorists with an explicit or implicit interest in approach and avoidance motivation.  Free Download Handbook Of Intensive Care Organization And Management English | 2016 | ISBN: 1783269502 | 423 Pages | PDF (True) | 9 MB The global trend of increasingly ageing societies and long term illnesses has meant a growth in demand for intensive care resources. This book advises on leadership and organizational development of intensive care units, in order to give best practices for governance, performance, emergency response and safety. Written by international experts in the field, each chapter allows researchers, clinicians and service providers worldwide to be able to refer to this single reference book. In seven parts, the volume will tackle aspects of intensive care management in both global and local contexts, and interrogate the key concerns that service providers face. It works as an informative guide for the practical administration of intensive care, as well as being international in its design and information.  Free Download Handbook Of Financial Econometrics, Statistics, Technology, And Risk Management (In 4 Volumes) English | 2025 | ISBN: 9819809940 | 5289 Pages | PDF (True) | 108 MB This handbook (in 4 volumes) investigates important tools for empirical and theoretical research in finance and accounting. Based on editors' and contributors' years of experience working in the industry, teaching classes, conducting research, writing textbooks, and editing journals on the subject of financial econometrics, mathematics, statistics, and technology, this handbook will review, discuss, and integrate theoretical, methodological, and practical issues of financial econometrics, mathematics, statistics, and machine learning.Volume 1 lays the groundwork with key methodologies and innovative approaches. From financial econometrics to the application of machine learning in risk management, this volume covers critical topics such as optimal futures hedging and the impacts of CEO compensation on corporate innovation. It also delves into advanced techniques in option bound determination, the influence of economic institutions on banking stability, and the latest in mortgage loan pricing predictions using ML-RNN, along with systemic risk assessment using bivariate copulas.Volume 2 explores sophisticated financial theories and machine learning applications.

Free Download Gödel's Theorems and Zermelo's Axioms: A Firm Foundation of Mathematics English | 2025 | ISBN: 3031851056 | 339 Pages | True PDF | 4 MB This book provides a concise and self-contained introduction to the foundations of mathematics. The first part covers the fundamental notions of mathematical logic, including logical axioms, formal proofs and the basics of model theory. Building on this, in the second and third part of the book the authors present detailed proofs of Gödel's classical completeness and incompleteness theorems. In particular, the book includes a full proof of Gödel's second incompleteness theorem which states that it is impossible to prove the consistency of arithmetic within its axioms. The final part is dedicated to an introduction into modern axiomatic set theory based on Zermelo's axioms, containing also a presentation of Gödel's constructible universe of sets. A recurring theme in the whole book consists of standard and non-standard models of several theories, such as Peano arithmetic, Presburger arithmetic and the real numbers. In addition, the corrected, revised and extended second edition now provides detailed solutions to all exercises. |
