Gasoline Compression Ignition Technology: Future Prospects (Energy, Environment, and Sustainability)

by Avinash Kumar Agarwal Gautam Kalghatgi Harsh Goyal Moez Ben Houidi

This book focuses on gasoline compression ignition (GCI) which offers the prospect of engines with high efficiency and low exhaust emissions at a lower cost. A GCI engine is a compression ignition (CI) engine which is run on gasoline-like fuels (even on low-octane gasoline), making it significantly easier to control particulates and NOx but with high efficiency. The state of the art development to make GCI combustion feasible on practical vehicles is highlighted, e.g., on overcoming problems on cold start, high-pressure rise rates at high loads, transients, and HC and CO emissions. This book will be a useful guide to those in academia and industry.

Gasotransmitters Signaling in Plants under Challenging Environment (Plant in Challenging Environments #5)

by Tariq Aftab Francisco J. Corpas

Abiotic stressors, such as drought, extreme temperatures, heavy metals, or high salinity, are causing huge crop losses worldwide. These abiotic stressors are expected to become more extreme, less predictable, and more widespread in the near future. The harm of abiotic stresses includes the disruption of cellular redox homeostasis, reactive oxygen species (ROS) production, and oxidative stress in the plant. Plants have different mechanisms to fight stress, and these mechanisms are responsible for maintaining the required homeostasis in plants. Research on gasotransmitters is rapidly expanding and knowledge regarding the potential of gasotransmitters in biology and medicine is accumulating. Over the past few decades, the roles of these signaling molecules, especially NO and H2S, have been extensively studied for their application in plants. Recently, the emissions of endogenous gasotransmitters in plants have been widely studied and analyzed, thereby providing information to facilitate our understanding of new gasotransmitters signaling pathways. Given the multidimensional role of these signaling molecules, research over the past decades in mitigating abiotic stresses in plant biology and from an agriculture point of view, we intend to bring forth a comprehensive volume “Gasotransmitters Signaling in Plants under Challenging Environment". We are hopeful that this comprehensive volume will furnish the requisite of all those who are working or have an interest in the proposed topic

Gastrophysics: The New Science of Eating

by Charles Spence

A ground-breaking book by the world-leading expert in sensory science: Freakonomics for foodWhy do we consume 35% more food when eating with one more person, and 75% more when with three? Why are 27% of drinks bought on aeroplanes tomato juice? How are chefs and companies planning to transform our dining experiences, and what can we learn from their cutting-edge insights to make memorable meals at home?These are just some of the ingredients of Gastrophysics, in which the pioneering Oxford professor Charles Spence shows how our senses link up in the most extraordinary ways, and reveals the importance of all the "off-the-plate" elements of a meal: the weight of cutlery, the colour of the plate (his lab showed that red is associated with sweetness - we perceive salty popcorn as tasting sweet when served in a red bowl), the background music and much more. Whether dining alone or at a dinner party, on a plane or in front of the TV, he reveals how to understand what we're tasting and influence what others experience. Meal-times will genuinely never be the same again.

Gated Communities and the Digital Polis: Rethinking Subjectivity, Reality, Exclusion, and Cooperation in an Urban Future (Advances in 21st Century Human Settlements)

by Kon Kim Heewon Chung

This edited collection provides an alternative discourse on cities evolving with physically and virtually networked communities—the ‘digital polis’—and offers a variety of perspectives from the humanities, media studies, geography, architecture, and urban studies. As an emergent concept that encompasses research and practice, the digital polis is oriented toward a counter-mapping of the digital cityscape beyond policing and gatekeeping in physical and virtual gated communities. Considering the digital polis as offering potential for active support of socially just and politically inclusive urban circumstances in ways that mirror the Greek polis, our attention is drawn towards the interweaving of the development of digital technology, urban space, and social dynamics. The four parts of this book address the formation of technosocial subjectivity, real-and-virtual combined urbanity, the spatial dimensions of digital exclusion and inclusion, and the prospect of emancipatory and empowering digital citizens. Individual chapters cover varied topics on digital feminism, data activism, networked individualism, digital commons, real-virtual communalism, the post-family imagination, digital fortress cities, rights to the smart city, online foodscapes, and open-source urbanism across the globe. Contributors explore the following questions: what developments can be found over recent decades in both physical and virtual communities such as cyberspace, and what will our urban future be like? What is the ‘digital polis’ and what kinds of new subjectivity does it produce? How does digital technology, as well as its virtuality, reshape the city and our spatial awareness of it? What kinds of exclusion and cooperation are at work in communities and spaces in the digital age? Each chapter responds to these questions in its own way, navigating readers through routes toward the digital polis.Chapter "Introduction - The digital polis and its practices: Beyond gated communities" is available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.

GATT Negotiations and the Political Economy of Policy Reform

by Gordon C. Rausser

This volume is dedicated to understanding the political economy obstacles to trade reform, especially global agricultural trade reform, and how these obstacles can be surmounted. The focus is on the trade reform under the GATT negotiations. New political-economic methodologies are used to assess and evaluate the obstacles and original scholarly analyses have been designed to explain why agriculture - among so many topics - became such a significant problem in the most recent Uruguay Round of the GATT.

Gauge Invariance Approach to Acoustic Fields

by Woon Siong Gan

This book highlights the symmetry properties of acoustic fields and describes the gauge invariance approach, which can be used to reveal those properties. Symmetry is the key theoretical framework of metamaterials, as has been demonstrated by the successful fabrication of acoustical metamaterials. The book first provides the necessary theoretical background, which includes the covariant derivative, the vector potential, and invariance in coordinate transformation. This is followed by descriptions of global gauge invariance (isotropy), and of local gauge invariance (anisotropy). Sections on time reversal symmetry, reflection invariance, and invariance of finite amplitude waves round out the coverage.

Gaussian Scale-Space Theory (Computational Imaging and Vision #8)

by Jon Sporring Mads Nielsen Luc Florack Peter Johansen

Gaussian scale-space is one of the best understood multi-resolution techniques available to the computer vision and image analysis community. It is the purpose of this book to guide the reader through some of its main aspects. During an intensive weekend in May 1996 a workshop on Gaussian scale-space theory was held in Copenhagen, which was attended by many of the leading experts in the field. The bulk of this book originates from this workshop. Presently there exist only two books on the subject. In contrast to Lindeberg's monograph (Lindeberg, 1994e) this book collects contributions from several scale­ space researchers, whereas it complements the book edited by ter Haar Romeny (Haar Romeny, 1994) on non-linear techniques by focusing on linear diffusion. This book is divided into four parts. The reader not so familiar with scale-space will find it instructive to first consider some potential applications described in Part 1. Parts II and III both address fundamental aspects of scale-space. Whereas scale is treated as an essentially arbitrary constant in the former, the latter em­ phasizes the deep structure, i.e. the structure that is revealed by varying scale. Finally, Part IV is devoted to non-linear extensions, notably non-linear diffusion techniques and morphological scale-spaces, and their relation to the linear case. The Danish National Science Research Council is gratefully acknowledged for providing financial support for the workshop under grant no. 9502164.
