The aim of this symposium was to bring together researchers, engineers, and civil aviation representatives working in the field of aircraft wakes. Aircraft wake research has been supported by many organizations such as FAA, NASA, DLR, ONERA, aircraft manufacturers and others, and significant advances have been made in prediction, methodology, and experimental techniques. A review of the state-of-the-art was appropriate. The aircraft separation necessary to avoid the hazard of vortex encounters must be maintained despite the increasing number of airports and of commercial aircraft per airport. In addition, wakes are becoming more and more important in the detection of military aircraft. Techniques leading to a premature vortex decay or breakdown are of great interest. Economically efficient aircraft spacing requires an accurate prediction of vortex formation, evolution, decay and breakdown. Presentations focused on the following areas: (1) Regulatory Viewpoints, (2) Aircraft Spacing Considerations, (3) Vortex Wake Structure, (4) Vortex Instabilities and Breakdown, (5) Aircraft Vortex Interactions, and (6) Atmospheric Effects on Wakes. Currently, operators and regulators are concerned with improved detection and avoidance procedures as a means to allow reduced aircraft separation near airports. The fluid dynamics community can contribute by providing better approximate models of wake decay, better models of rolling moments for various generating aircraft, and better predictions and means of detecting vortex wakes.
El Nino, caprice of the heavens, scapegoat for every calamity? The general public cannot really understand what is behind the El Nino phenomenon. The book offers a tour of the Earth's climate to understand one of its normal but extreme components.
Contemporary Criminological Issues tackles some of today’s most pressing social issues, from the criminalization of Indigenous peoples to interpersonal violence, border control, and armed conflicts. This book advances cutting-edge theories and methods, with the aim of moving beyond the scholarship that reproduces insecurity and exclusion. The breadth of approaches encompasses much of the current critical criminological scholarship, serving as a counterpoint to the growth of managerial and administrative criminologies and the rise of explicitly exclusionary and punitive state policies and practices with respect to ‘crime’ and ‘security.’ This edited collection featuring two books, one in English and one in French, includes important contributions to knowledge and public policy by eminent experts and emerging scholars. This book is published in English.
"A new novel from the author of Oleander Girl, a novel in stories, built around crucial moments in the lives of 3 generations of women in an Indian/Indian-American Family"--
The essays in this edited volume, written in English and French, tackle the intriguing problems of fear and safety by analysing their various meanings and manifestations in literature and other narrative media. The articles bring forth new, cross-cultural interpretations on fear and safety through examining what kinds of genre-specific means of world-making narratives use to express these two affectivities. The articles also show how important it is to study these themes in order to understand challenges in times of global threats, such as the climate crisis, and - to imagine a better future. The main themes of the book are approached from various theoretical perspectives as related to their literary and cultural representations. Recent trends in research, such as affect and risk theory, serve as the basis for the discussion. Many of the articles in the volume discuss apocalyptic and dystopian narratives that currently permeate the entire cultural landscape. Dystopian narratives do not only deal with future threats, such as totalitarianism, technocracy, or environmental disasters, but also suggest alternative ways of being and new hopes in the form of political resistance. The articles in the volume also draw from disciplines such as gender studies and trauma studies to examine the threats posed by collective fears and aggression on individuals' lives and propose ways of coping with fear. These themes are addressed also in articles analysing new adaptations of old myths that retell stories of the past.
The future evolution of the debris environment will be forecast on the basis of traffic models and possible hazard mitigation practices. The text shows how large trackable objects will have re-entry pinpointed and predictions made on related risk assessment for possible ground impact. Models will also be described for meteoroids which are also a prevailing risk.
