Making Space: How the Brain Knows Where Things Are
Knowing where things are seems effortless. Yet our brains devote tremendous computational power to figuring out the simplest details about spatial relationships. Going to the grocery store or finding our cell phone requires sleuthing and coordination across different sensory and motor domains. Making Space" traces this mental detective work to explain how the brain creates our sense of location. But it goes further, to make the case that spatial processing permeates all our cognitive abilities, and that the brain s systems for thinking about space may be the systems of thought itself. Our senses measure energy in the form of light, sound, and pressure on the skin, and our brains evaluate these measurements to make inferences about objects and boundaries. Jennifer Groh describes how eyes detect electromagnetic radiation, how the brain can locate sounds by measuring differences of less than one one-thousandth of a second in how long they take to reach each ear, and how the ear s balance organs help us monitor body posture and movement. The brain synthesizes all this neural information so that we can navigate three-dimensional space. But the brain s work doesn t end there. Spatial representations do double duty in aiding memory and reasoning. This is why it is harder to remember how to get somewhere if someone else is driving, and why, if we set out to do something and forget what it was, returning to the place we started can jog our memory. In making space the brain uses powers we did not know we have."

Whitlam

Brian Carroll, "Whitlam"
English | ISBN: 1921719133 | 2011 | EPUB | 256 pages | 9 MB

Whitlam
Edward Gough Whitlam was one of the most momentous figures in Australian political history. Born into a privileged life that should have seen him on the side with the 'born-to-rule gang,' Whitlam took a different path and joined the Australian Labor Party. Although he was branded as a 'silver tail' (one who is considered wealthy, usually by inherited money) by the rough and ready men of Labor, Whitlam fought to convince Labor that they were something more than just the political arm of the union movement, and that principle without power was an exercise in futility. He overcame party resistance and, in 1972, led Labor triumphantly into the government benches, where he became Parliamentary leader. However, the pace of change scared too many people and sudden developments in the world economic environment brought challenges Whitlam could not overcome. Nor could he overcome the local political challenges thrown down by the conservative forces, once they had recovered from the shock of the 1972 election results. Whitlam held them at bay when they forced him to the electors 18 months ahead of schedule in mid-1974. Although he won the election with a reduced majority, he and his colleagues seemed determined to continue providing the opposition with the ammunition needed to shoot him down, and on November 11, 1975, they finally did. This book recaptures the excitement of one of the most contentious and momentous events in Australian political history.

Study and Design of Differential Microphone Arrays

FREEDownload : Study and Design of Differential Microphone Arrays

Jacob Benesty, Jingdong Chen, "Study and Design of Differential Microphone Arrays"
English | 2013 | ISBN-10: 364233752X, 3642427561 | 180 pages | PDF | 6 MB

Study and Design of Differential Microphone Arrays
Microphone arrays have attracted a lot of interest over the last few decades since they have the potential to solve many important problems such as noise reduction/speech enhancement, source separation, dereverberation, spatial sound recording, and source localization/tracking, to name a few. However, the design and implementation of microphone arrays with beamforming algorithms is not a trivial task when it comes to processing broadband signals such as speech. Indeed, in most sensor arrangements, the beamformer output tends to have a frequency-dependent response. One exception, perhaps, is the family of differential microphone arrays (DMAs) who have the promise to form frequency-independent responses. Moreover, they have the potential to attain high directional gains with small and compact apertures. As a result, this type of microphone arrays has drawn much research and development attention recently. This book is intended to provide a systematic study of DMAs from a signal processing perspective. The primary objective is to develop a rigorous but yet simple theory

for the design, implementation, and performance analysis of DMAs. The theory includes some signal processing techniques for the design of commonly used first-order, second-order, third-order, and also the general Nth-order DMAs. For each order, particular examples are given on how to form standard directional patterns such as the dipole, cardioid, supercardioid, hypercardioid, subcardioid, and quadrupole. The study demonstrates the performance of the different order DMAs in terms of beampattern, directivity factor, white noise gain, and gain for point sources. The inherent relationship between differential processing and adaptive beamforming is discussed, which provides a better understanding of DMAs and why they can achieve high directional gain. Finally, we show how to design DMAs that can be robust against white noise amplification.

Category Theory for the Sciences

Category Theory for the Sciences by David I. Spivak
2014 | ISBN: 0262028131 | English | 496 pages | PDF | 7 MB

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.

Contestation and Adaptation: The Politics of National Identity in China

FREEDownload : Contestation and Adaptation: The Politics of National Identity in China

Enze Han, "Contestation and Adaptation: The Politics of National Identity in China"
2013 | ISBN-10: 0199936293 | 240 pages | PDF | 13 MB

Contestation and Adaptation: The Politics of National Identity in China
Contestation and Adaptation unravels the complexities of national-identity contestation among various ethnic minority groups in China. It focuses on the interactions between domestic and international forces that inform ethnic groups' national-identity contestation, positing a theoretical framework where international factors play a significant role in determining why and when ethnic groups will contest the national identities imposed on them by central governments as part of the nation-building process.

Simmering grievances and occasional outbursts of social unrest among ethnic minority populations in China challenge not only the ruling party's legitimacy and governance, but also contemporary Chinese national identity and the territorial integrity of the Chinese state. But, as Enze Han points out, of the fifty-five ethnic minority groups in China, only the Tibetans and Uyghurs have forcefully contested the idea of a Chinese national identity. He argues that whether ethnic groups contest those national identities depends on whether they perceive a better, achievable alternative. In particular, Han argues that ethnic groups with extensive external kinship networks are most likely to perceive a capacity to achieve better circumstances and are, therefore, more likely to politically mobilize to contest national identity. In the absence of such alternatives ethnic groups are more likely to cope with their situation through emigration, political ambivalence, or assimilation. Using this theoretical framework, the book compares the way that five major ethnic minority groups in China negotiate their national identities with the Chinese nation-state: Uyghurs, Chinese Koreans, Dai, Mongols, and Tibetans. Overall, Contestation and Adaptation sheds light on the nation-building processes in China over the past six decades and the ways that different groups have resisted or acquiesced in their dealings with the Chinese state and majority Han Chinese society.

2014 | ISBN: 0643107568 | English | 306 pages | PDF | 54 MB

Living Waters: Ecology of Animals in Swamps, Rivers, Lakes and Dams
Wetlands are often seen as the ultimate symbol of beauty and tranquillity, their clear waters sheltering mysterious animals in a world where change is gentle and slow, from dragonflies skimming above their own reflections to the fishes glimpsed briefly below. Yet Australian wetlands are among the most varied and changeable habitats found anywhere, and the many creatures that live out their lives in and around water are superbly adapted to some of the most unpredictable ecosystems in the world.This book follows the diverse common themes and patterns that link inland waters from Tasmania to the tropics. It shows how cycles of change, the ways that different wetland animals travel through and between wetlands, and the interactions of the animals themselves create an ever-changing ecological kaleidoscope.
