Название: The Lazy Universe: An Introduction to the Principle of Least Action

Формат: True PDF

This is a rare book on a rare topic: it is about 'action' and the Principle of Least Action. A surprisingly well-kept secret, these ideas are at the heart of physical science and engineering. Physics is well known as being concerned with grand conservatory principles (e.g. the conservation of energy) but equally important is the optimization principle (such as getting somewhere in the shortest time or with the least resistance). The book explains: why an optimization principle underlies physics, what action is, what `the Hamiltonian' is, and how new insights into energy, space, and time arise. It assumes some background in the physical sciences, at the level of undergraduate science, but it is not a textbook. The requisite derivations and worked examples are given but may be skim-read if desired.

Green pesticides, also called ecological pesticides, are pesticides derived from organic sources which are considered environmentally friendly and are causing less harm to human and animal health and to habitats and the ecosystem. Essential oils based insecticides started have amazing features. This book gives a full spectrum of the whole range of essential oil based pesticides that may be used in pest control. It discusses the uses and limitations, including the recent advances in this area. It describes the metabolism and mode of action, and provides the present status of essential oil based pesticide residues in foodstuffs, soil and water.

Increase the photorealism of your 3d visualizations with enhanced toolsets of V-ray in 3ds Max. Full-color, step-by-step tutorials about techniques involved in creating photorealistic renders for interior/exterior scenes. Each tutorial includes a 3d project scene to guide you through, production and post-production. The production chapter shows how to create shaders, fine-tune textures and set up a day/night lighting rig. You will be rendering high-res images with render elements included for the final stage of post-production. The book also includes tips about, pre-production, camera settings, verified views, material editors, shaders, 3ds max scripts, and much more!

Название: The Story of Be: A Verb's-Eye View of the English Language

It's the most simple, unassuming, innocent-looking verb: to be. Yet it is jam-packed with more different meanings, forms, and uses than any other English word. As he reveals be's multiple incarnations, David Crystal takes us to the heart of our flexible and changing language. He tells the intriguing story in 26 chapters, each linked to a particular usage. We meet circumstantial be ("how are you?"), numerical be ("two and two is four"), quotative be ("so I was like, 'wow'"), and ludic be ("oh no he isn't!"), and a whole swarm of other meanings. Bringing the ideas to life are a host of examples from sources as varied as Beowulf, Jane Austen, pantomime, Hamlet (of course), and Star Wars, with cartoons from Ed McLachlan and Punch peppered throughout. Full of fascinating nuggets of information, it is a book to delight any lover of words and language.

Theoretical and practical interests in additive manufacturing (3D printing) are growing rapidly. Engineers and engineering companies now use 3D printing to make prototypes of products before going for full production. In an educational setting faculty, researchers, and students leverage 3D printing to enhance project-related products. Additive Manufacturing Handbook focuses on product design for the defense industry, which affects virtually every other industry. Thus, the handbook provides a wide range of benefits to all segments of business, industry, and government. Manufacturing has undergone a major advancement and technology shift in recent years.

Due to the increasing world population, energy consumption is steadily climbing, and there is a demand to provide solutions for sustainable and renewable energy production, such as wind turbines and photovoltaics. Power electronics are being used to interface renewable sources in order to maximize the energy yield, as well as smoothly integrate them within the grid. In many cases, power electronics are able to ensure a large amount of energy saving in pumps, compressors, and ventilation systems. This book explains the operations behind different renewable generation technologies in order to better prepare the reader for practical applications. Multiple chapters are included on the state-of-the-art and possible technology developments within the next 15 years.

Название: Control and Dynamics in Power Systems and Microgrids
Автор: Lingling Fan
Издательство: CRC Press
Год: 2017
Формат: True PDF
Страниц: 227
Размер: 19.5 Mb
Язык: English

In traditional power system dynamics and control books, the focus is on synchronous generators. Within current industry, where renewable energy, power electronics converters, and microgrids arise, the related system-level dynamics and control need coverage. Wind energy system dynamics and microgrid system control are covered. The text also offers insight to using programming examples, state-of-the-art control design tools, and advanced control concepts to explain traditional power system dynamics and control. The reader will gain knowledge of dynamics and control in both synchronous generator-based power system and power electronic converter enabled renewable energy systems, as well as microgrids.

Dosimetry refers to the calculation and assessment of the radiation dose received by the human body. The proposed book will place emphasis on the existence of physical and biophysical dosimetry. It will be discussed for the proper description and evaluation of the signal at the power generation system. It will cover in detail 10 different parameters of EMF (electromagnetism) exposure such as amplitude, frequency, vector, time of exposure, orientation, etc. In most published papers, these parameters are not well defined.
