Acoustics (from Greek ακουστικός pronounced akoustikos meaning "of or for hearing, ready to hear") is the science that studies sound, in particular its production, transmission, and effects. The science of acoustics has many applications which are dependent upon the nature of the sound that is to be produced, transmitted or controlled.

This book aims to be an accessible introduction into the design and analysis of efficient algorithms. Throughout the book we will introduce only the most basic techniques and describe the rigorous mathematical methods needed to analyze them.

The topics covered include:

The divide and conquer technique.
The use of randomization in algorithms.
The general, but typically inefficient, backtracking technique.
Dynamic programming as an efficient optimization for some backtracking algorithms.
Greedy algorithms as an optimization of other kinds of backtracking algorithms.
Hill-climbing techniques, including network flow.

The goal of the book is to show you how you can methodically apply different techniques to your own algorithms to make them more efficient. While this book mostly highlights general techniques, some well-known algorithms are also looked at in depth. This book is written so it can be read from "cover to cover" in the length of a semester, where sections marked with a * may be skipped.

Veterinary nurses need to have a firm grasp of the normal structure of an animal’s body and how it functions before they can understand the effect diseases and injuries have and the best ways to treat them. This book describes the structure of the animal body and the way in which it works. Animals encountered in normal veterinary practice are used as examples where possible.

The conversation includes Arabic text, transliteration, and translation.

The history of Art is long and varied, spanning tens of thousands of years from ancient paintings on the walls of caves
to the glow of computer-generated images on the screens of the 21st century.

A computer is an automatic, electronic, data-processing machine that takes in facts and figures known as data, and then processes or organizes it in some useful way. Afterwards it outputs, or displays, the results for you to see as information. Keep in mind that data is not information. Rather, information is the knowledge that you, the end-user, derive from accurate data that are entered into a computer. Only after processing, is data transformed into information which is then used for decision making. (Almost) each part of a computer can be classified as either hardware or software.

Nuclear Medicine is a fascinating application of nuclear physics. The first ten chapters of this wikibook are intended to support a basic introductory course in an early semester of an undergraduate program. They assume that students have completed decent high school programs in maths and physics and are concurrently taking subjects in the medical sciences. Additional chapters cover more advanced topics in this field. Our focus in this wikibook is the diagnostic application of Nuclear Medicine. Therapeutic applications are considered in a separate wikibook, "Radiation Oncology".

Public affairs writing is the term used for publications written with the need of expressing opinions, ideas or concerns to a targeted audience. It is also used simply as a source of informing. Some common forms of public affairs writing include letters to the newspaper editor, letters to the government official, or e-mails and blogs. The content is written with the goal to inform or persuade the audience.

This book,"Blended Learning in K-12", is an overview of the concept of "blended learning" and how it relates to the integration of technologies in the K-12 environment. Dr. N.I. Scagnoli, the course instructor, has guided the students of the CTER 7 cohort in the creation of this book. This could not have happened in the 1980s. (By way of explanation to non-Americans, K-12 means all primary and secondary schooling).

Blender 3D: Noob to Pro is a product of shared effort by numerous team members and anonymous editors. Its purpose is to teach people how to create three-dimensional computer graphics using Blender, a free software application. This book is intended to be used in conjunction with other on-line resources that complement it.

Although C# is derived from the C programming language, it introduces some unique and powerful features, such as delegates (which can be viewed as type-safe function pointers) and lambda expressions which introduce elements of functional programming languages, as well as a simpler single class inheritance model (than C++) and, for those of you with experience in "C-like" languages, a very familiar syntax that may help beginners become proficient faster than its predecessors. Similar to Java, it is object-oriented, comes with an extensive class library, and supports exception handling, multiple types of polymorphism, and separation of interfaces from implementations. Those features, combined with its powerful development tools, multi-platform support, and generics, make C# a good choice for many types of software development projects: rapid application development projects, projects implemented by individuals or large or small teams, Internet applications, and projects with strict reliability requirements. Testing frameworks such as NUnit make C# amenable to test-driven development and thus a good language for use with Extreme Programming (XP). Its strong typing helps to prevent many programming errors that are common in weakly typed languages.

C is the most commonly used programming language for writing operating systems. The first operating system written in C is Unix. Later operating systems like GNU/Linux were all written in C. Not only is C the language of operating systems, it is the precursor and inspiration for almost all of the most popular high-level languages available today. In fact, Perl, PHP, Python and Ruby are all written in C. By way of analogy, let's say that you were going to be learning Spanish, Italian, French, or Portuguese. Do you think knowing Latin would be helpful? Just as Latin was the basis of all of those languages, knowing C will enable you to understand and appreciate an entire family of programming languages built upon the traditions of C. Knowledge of C enables freedom.

Cognitive Psychology is a psychological science which is interested in various mind and brain related subfields such as cognition, the mental processes that underlie behavior, reasoning and decision making.

This book is an introduction to communication theory — the theory of how humans share, encode, and decode what they know, what they need, and what they expect from each other.

Everyone has their own view of the nature of consciousness based on their education and background. The intention of this book is to expand this view by providing an insight into the various ideas and beliefs on the subject as well as a review of current work in neuroscience. The neuroscientist should find the philosophical discussion interesting because this provides first-person insights into the nature of consciousness and also provides some subtle arguments about why consciousness is not a simple problem. The student of philosophy will find a useful introduction to the subject and information about neuroscience and physics that is difficult to acquire elsewhere.

Control Systems is an inter-disciplinary engineering text that analyzes the effects and interactions of mathematical systems. This book is for third and fourth year undergraduates in an engineering program.

This webpage provides over 20 basic conversational phrases and terms, all of which are used in most everyday discussions across the Arabic-speaking world. The terms and phrases are presented in transliterated form with English translation; no Arabic script is used.

One of the many challenges facing the countries in the Asia-Pacific today is preparing their societies and governments for globalization and the information and communication revolution. Policy-makers, business executives, NGO activists, academics, and ordinary citizens are increasingly concerned with the need to make their societies competitive in the emergent information economy.

The e-ASEAN Task Force and the UNDP Asia Pacific Development Information Programme (UNDP-APDIP) share the belief that with enabling information and communication technologies (ICTs), countries can face the challenge of the information age. With ICTs they can leap forth to higher levels of social, economic and political development. We hope that in making this leap, policy and decision-makers, planners, researchers, development practitioners, opinion-makers, and others will find this series of e-primers on the information economy, society, and polity useful.

This style guide is an introductory wikibook for beginners who want to produce political messages in various media formats. It is not a rule book; rather, it is a set of guidelines to facilitate effective political communication. Its purpose is to bridge the gap between two distinct styles to create pragmatic, clear, and useful information to establish a consistent tone, style, and format between all of the messages you or your organization produces.

It is meant as a practical guide for anyone, regardless of political affiliation, and it is organized in such a way that a person new to political communication can learn to create convincing and thought-provoking op-eds, letters to the editor, press releases, social media posts, website content, and spoken messages.

This textbook is written for an audience of introductory college students in a non-science degree program.

As a major scientific overview of the entirety of Planet Earth, the intention is to only present key concepts that will enhance, enrich, and engage the readers interest in Earth Sciences. It is intended to make any reader, such as yourself, at least a little more knowledgeable of the amazing place that we all live within. Hosted as a WikiBook.

This project discovers the history of Modern Europe, starting at the Hundred Years War and ending at the present time.
A chronological perspective of history is attempted within this text. Although this is the case, it is also important to understand patterns within European History, therefore chapters will attempt to cover a breadth of material even though their titles might be that of a specific pattern in history rather than a time period.

This book covers in depth all topics required for a standard first aid course, and also includes a section on advanced topics. The basics covered include: Primary assessment and cardiopulmonary resuscitation (CPR); Legal aspects of first aid, including negligence and consent; Circulatory emergencies, such as bleeding, heart attack and stroke; Respiratory emergencies, such as asthma and anaphylactic shock; Internal injuries, such as broken bones, chest injuries, and internal bleeding; Burns, seizures and other medical conditions.

This book is aimed at undergraduate civil engineering students, though the material may provide a useful review for practitioners and graduate students in transportation. Typically, this would be for an Introduction to Transportation course, which might be taken by most students in their sophomore or junior year. Often this is the first engineering course students take, which requires a switch in thinking from simply solving given problems to formulating the problem mathematically before solving it, i.e. from straight-forward calculation often found in undergraduate Calculus to vaguer word problems more reflective of the real world.

The word biology means, "the science of life", from the Greek bios, life, and logos, word or knowledge. Therefore, Biology is the science of Living Things. That is why Biology is sometimes known as Life Science.

The modern human experience places a large emphasis upon the material world. From the day of our birth to the day we die, we are frequently preoccupied with the world around us. Whether struggling to feed ourselves, occupying ourselves with modern inventions, interacting with other people or animals, or simply meditating on the air we breathe, our attention is focused on different aspects of the material world. In fact only a handful of disciplines—certain subsets of religion, philosophy, and abstract math—can be considered completely unrelated to the material world. Everything else is somehow related to chemistry, the scientific discipline which studies the properties, composition, and transformation of matter.

In this book we aim to introduce you both to the Haskell language, from the very basics to advanced features, and to computer programming in general. We urge seasoned programmers to be especially patient with this process. In all likelihood, the languages you are most familiar with differ greatly from Haskell, and habits from those languages might make it more difficult to understand how things work − they are simple, but different. Face learning to see the world through the warped mindset of a functional programmer as an adventure in a brave new world, which will bring you understanding valuable far beyond the boundaries of any language.

This module is developed for High school students . This module is about water pollution, its types and its effect on health and environment.

This online textbook is intended for, but not limited to, 14 to 18 year old teenagers who have a general interest in mathematics. The text's language is aimed at high school students without a rigorous understanding and knowledge of university-level mathematics.

This book introduces several interesting topics not covered in the standard high school curriculum of most countries.

The materials presented can be challenging, but at the same time, we strive to make this book readable to all with 9–10 years of formal education.

Geology can roughly be divided into physical geology, which studies the materials of the Earth and the processes operating in it, and historical geology, which aims at a reconstruction of the history of the Earth. Historical geology requires some knowledge of physical geology for its elucidation. (Imagine, by way of analogy, forensic scientists diagnosing cause of death as a gunshot wound, which is a historical question. It would obviously be necessary for them to know something about the behavior of guns, which would be a physical question.) However, the aim of historical geology is to understand the past, and knowledge of physical geology is merely an adjunct to this aim.

Building a computer can be a very rewarding experience. Since you’re reading this, you’re probably thinking about building your next computer instead of buying one pre-built. This is a very viable option these days and can bring many benefits; you can learn a lot about computer hardware by building one, you get a totally personalized computer, you can choose better components and you may be able to save some money and have fun. Additionally, if you are the sort of person who wants to understand how things work, if you take broken stuff apart just to see how it all fits together, if you have a drawer somewhere full of “parts” you think may come in handy someday, then you just may be in the right place.

Physiology The word physiology is from the Ancient Greek φυσιολογία (phusiología, "natural philosophy") and it is the study of how organisms perform their vital functions. An example is the study of how a muscle contracts or the force contracting muscles exert on the skeleton. It was introduced by French physician Jean Fernery in 1552. Physiology is built upon a tripod of sciences: physics, chemistry, and anatomy.

Dear student! You are starting to learn about computation and its purpose. This course covers the same materials as an introductory class for undergraduate computer science majors. Its curriculum, which includes software, hardware and algorithms, resembles that of a one- or two-semester first-year college course or the high school Advanced Placement (AP) Computer Science. It does not require a formal computer science background.

Library and Information Science (LIS) is the academic and professional study of how information and information carriers are produced, disseminated, discovered, evaluated, selected, acquired, used, organized, maintained, and managed. This book intends to introduce the reader to fundamental concerns and emerging conversations in the field of library and information science.

A secondary goal of this book is to introduce readers to prominent writers, articles, and books within the field of library science. The book originated as a collection of annotations of important LIS articles. Though these citations are being developed into a fuller text, we hope that this book remains firmly rooted in the literature of LIS and related fields, and helps direct readers toward important resources when a particular topic strikes their fancy.
