Category Theory for the Sciences by David I. Spivak

Category Theory for the Sciences
Category theory was invented in the 1940s to unify and synthesize different areas in mathematics, and it has proven remarkably successful in enabling powerful communication between disparate fields and subfields within mathematics. This book shows that category theory can be useful outside of mathematics as a rigorous, flexible, and coherent modeling language throughout the sciences. Information is inherently dynamic; the same ideas can be organized and reorganized in countless ways, and the ability to translate between such organizational structures is becoming increasingly important in the sciences. Category theory offers a unifying framework for information modeling that can facilitate the translation of knowledge between disciplines. Written in an engaging and straightforward style, and assuming little background in mathematics, the book is rigorous but accessible to non-mathematicians. Using databases as an entry to category theory, it begins with sets and functions, then introduces the reader to notions that are fundamental in mathematics: monoids, groups, orders, and graphs — categories in disguise. After explaining the "big three" concepts of category theory — categories, functors, and natural transformations — the book covers other topics, including limits, colimits, functor categories, sheaves, monads, and operads. The book explains category theory by examples and exercises rather than focusing on theorems and proofs. It includes more than 300 exercises, with selected solutions. is intended to create a bridge between the vast array of mathematical concepts used by mathematicians and the models and frameworks of such scientific disciplines as computation, neuroscience, and physics.

2014 | ISBN: 1430265442 | English | 260 pages | PDF | 5 MB

Practical Hadoop Security
is an excellent resource for administrators planning a production Hadoop deployment who want to secure their Hadoop clusters. A detailed guide to the security options and configuration within Hadoop itself, author Bhushan Lakhe takes you through a comprehensive study of how to implement defined security within a Hadoop cluster in a hands-on way.

You will start with a detailed overview of all the security options available for Hadoop, including popular extensions like Kerberos and OpenSSH, and then delve into a hands-on implementation of user security (with illustrated code samples) with both in-the-box features and with security extensions implemented by leading vendors.

No security system is complete without a monitoring and tracing facility, so next steps you through audit logging and monitoring technologies for Hadoop, as well as ready to use implementation and configuration examples–again with illustrated code samples.

The book concludes with the most important aspect of Hadoop security – encryption. Both types of encryptions, for data in transit and data at rest, are discussed at length with leading open source projects that integrate directly with Hadoop at no licensing cost.

:

Explains importance of security, auditing and encryption within a Hadoop installation
Describes how the leading players have incorporated these features within their Hadoop distributions and provided extensions
Demonstrates how to set up and use these features to your benefit and make your Hadoop installation secure without impacting performance or ease of use

What you'll learn

The Uncanny Valley in Games and Animation by Angela Tinwell
2014 | ISBN: 146658694X | English | 236 pages | PDF | 11 MB

The Uncanny Valley in Games and Animation
Advances in technology have enabled animators and video game designers to design increasingly realistic, human-like characters in animation and games. Although it was intended that this increased realism would allow viewers to appreciate the emotional state of characters, research has shown that audiences often have a negative reaction as the human likeness of a character increases. This phenomenon, known as the Uncanny Valley, has become a benchmark for measuring if a character is believably realistic and authentically human like. This book is an essential guide on how to overcome the Uncanny Valley phenomenon when designing human-like characters in digital applications.

In this book, the author provides a synopsis of literature about the Uncanny Valley phenomenon and explains how it was introduced into contemporary thought. She then presents her theories on its possible psychological causes based on a series of empirical studies. The book focuses on how aspects of facial expression and speech can be manipulated to overcome the Uncanny Valley in character design.

presents a novel theory that goes beyond previous research in that the cause of the Uncanny Valley is based on a perceived lack of empathy in a character. This book makes an original, scholarly contribution to our current understanding of the Uncanny Valley phenomenon and fills a gap in the literature by assessing the biological and social roots of the Uncanny Valley and its implications for computer-graphics animation.

Biomimetic Architectures by Plasma Processing: Fabrication and Applications

FREEDownload : Biomimetic Architectures by Plasma Processing: Fabrication and Applications

Biomimetic Architectures by Plasma Processing: Fabrication and Applications by Surojit Chattopadhyay
English | 2014 | ISBN: 9814463949 | 254 pages | PDF | 30 MB

Biomimetic Architectures by Plasma Processing: Fabrication and Applications
Plasma-processed biomimetic structures are an extremely focused and small subset of biomimetics. Although other methods can also be adopted, experimental synthesis of biomimetic structures mainly focuses on plasma processing. This book deals with the theoretical description of photonic structures available in nature, and the physics and applications of biomimetic structures prepared in the laboratory. It discusses anti-reflection properties of moth eye- or cicada wing-type nanostructured materials on semiconductor surfaces, with emphasis on plasma fabrication procedures. It also explains, with the help of related theories, the superhydrophobic or hydrophilic wetting properties demonstrated by most of these natural structures. It discusses biomedical applications, especially in implants, as one of the key applications of such materials.
The book focuses mainly on plasma processing of biomimetic nanostructures and is, therefore, different from similar books that are more general in nature. It presents essential schematics, sufficient details, and advanced instrumentation techniques that would help readers understand why these structures are considered so important in materials science and physics.

The Creating Brain: The Neuroscience of Genius

The Creating Brain: The Neuroscience of Genius by Nancy C. Andreasen
English | 2005-11-30 | ISBN: 1932594078 | PDF | 197 pages | 1,1 MB

The Creating Brain: The Neuroscience of Genius
Michelangelo was raised in a rustic village by a family of modest means. Shakespeare's father was a middle-class businessman. Abraham Lincoln came from a family of itinerant farmers. Yet all these men broke free from their limited circumstances and achieved brilliant careers as creative artists and leaders. How such extraordinary creativity develops in the human brain is the subject of renowned psychiatrist Nancy Andreasen's The Creating Brain.
Andreasen explains here how the brain produces creative breakthroughs in art, literature, and science, revealing that creativity is not the same thing as intelligence. She scrutinizes the complex factors involved in the development of creativity, including the role of patrons and mentors, "non-standard" educations, and the possession of an "omnivorous" vision. A fascinating interview with acclaimed playwright Neil Simon sheds further light on the creative process.The relationship between genius and insanity also plays an important role in Andreasen's examination. Drawing on her studies of writers in the Iowa Writers' Workshop and other scientific evidence, Andreasen asserts that while creativity may sometimes be linked to mental disorders and may be partially due to familial/genetic factors, neither is inevitable nor needed for creativity to flourish.
Scientist's increasing understanding of the brain's plasticity suggests even more possibilities for nurturing the creative drive, and Andreasen looks ahead to exciting implications for child-rearing and education. The Creating Brain presents an inspiring vision for a future where everyone-not just artists or writers-can fulfill their creative capacity.
