The ill-posed inversion of multiwavelength lidar data by a hybrid method of variable projection
(1999)
This book offers a comprehensive, multidisciplinary introduction to theme parks and the field of theme park studies. It identifies and discusses relevant economic, social, and cultural as well as medial, historical, and geographical aspects of theme parks worldwide, from the big international theme park chains to smaller, regional, family-operated parks. The book also describes the theories and methods that have been used to study theme parks in various academic disciplines and reviews the major contexts in which theme parks have been studied. By providing the necessary backgrounds, theories, and methods to analyze and understand theme parks both as a business field and as a socio-cultural phenomenon, this book will be a great resource to students, academics from all disciplines interested in theme parks, and professionals and policy-makers in the leisure and entertainment as well as the urban planning sector.
The Tetrarchy as Ideology
(2023)
The 'Tetrarchy', the modern name assigned to the period of Roman history that started with the emperor Diocletian and ended with Constantine I, has been a much-studied and much-debated field of the Roman Empire. Debate, however, has focused primarily on whether it was a true 'system' of government, or rather a collection of ad-hoc measures undertaken to stabilise the empire after the troubled period of the 3rd century CE. The papers collected here aim to go beyond this question and to present an innovative approach to a fascinating period of Roman history by understanding the Tetrarchy not as a system of government, but primarily as a political language. Their focus thus lies on the language and ideology of the imperial college and court, on the performance of power in imperial ceremonies, the representation of the emperors and their enemies in the provinces of the Roman world, as well as on the afterlife of Tetrarchic power in the Constantinian period.
Norm behavior of a parabolic-elliptic system modelling chemotaxis in three-dimensional domains
(2002)
Oases is a special ecosystem formed in arid climate and hungriness environment, in which resident, water and soil are the principal factor and exchanges of materials, energy and information are the main functional characteristics. The oases regions in central Asia are not only the basilic cradle of civilization of human beings, but also the important strategic places in world growing awareness of the potential benefits. We choose Keriya River Basin oases in south of Xinjiang as a case to study critical controlling of Oases Evolution, Based on the theories and methods used for environmental geology, physical geography, land resource research, and oases ecology. This study try to indicate the essential factors driving the oases ecosystem and the interactional dynamic mechanism in different scales and levels, confirm the optimal equilibrium aggregate of harmonious development between Population, Resources, Environment and Development, and establish the critical controlling pattern of sustainable development. We advance the indicator system to research the evolution of the PRED System of oases in Keriya River valley oases, in basis of the information derived from the field investigation and local materials. According to inquisitional result based on technical support of Geographic Information System (GIS) and Remote Sense (RS), the comparisons and analyses are carried out in land use at the upper reaches, vegetation change in the middle reaches, and desertification at the lower reaches, which narrates the regulations of Keriya River Valley oases land cover dynamic change. The main land cover types represent distinct characteristics of the local place. On the basis of field survey and statistical data, we use ARCINFO software to preprocess these data and the 2 TM satellite images. Through analyzing these images resulting from post- classification compare, we sums up the concrete quantificational dynamic distributed data of 13 land types covering a span of 15 years and regulation of the local ecological environment system. It finally points out that the trend of Keriya River Valley oases desertification expansion is mainly related to two important reasons: impact of natural environment and impact of human activities.
Faced with an accelerating climate crisis caused by burning fossil fuels we have to change the way the economy works. We can no longer go on with a system that just maximises private profit without consideration for its effects. Instead we have to conciously plan how to change to a fossil fuel free society.
The need is urgent.
The transformation will be vast.
Nothing similar has been done in the West since the days of wartime mobilisation.
This book explains the basic science of climate change before looking at the transformations needed to our energy and basic industries. It looks at the previous successful history of deliberate planning practiced in the UK from 1939 to the 1960s and how, using modern computing techniques it will be possible to organise resources so as to effect the change.
Interactional linguistics
(2018)
The first textbook dedicated to interactional linguistics, focusing on linguistic analyses of conversational phenomena, this introduction provides an overview of the theory and methodology of interactional linguistics. Reviewing recent findings on linguistic practices used in turn construction and turn taking, repair, action formation, ascription, and sequence and topic organization, the book examines the way that linguistic units of varying size - sentences, clauses, phrases, clause combinations, and particles - are mobilized for the implementation of specific actions in talk-in-interaction. A final chapter discusses the implications of an interactional perspective for our understanding of language as well as its variation, diversity, and universality. Supplementary online chapters explore additional topics such as the linguistic organization of preference, stance, footing, and storytelling, as well as the use of prosody and phonetics, and further practices with language. Featuring summary boxes and transcripts from recordings of everyday conversation, this is an essential resource for advanced undergraduate and postgraduate courses on language in social interaction.
We determine the ground state properties of inhomogeneous mixtures of bosons and fermions in cubic lattices and parabolic confining potentials. For finite hopping we determine the domain boundaries between Mott-insulator plateaux and hopping-dominated regions for lattices of arbitrary dimension within mean-field and perturbation theory. The results are compared with a new numerical method that is based on a Gutzwiller variational approach for the bosons and an exact treatment for the fermions. The findings can be applied as a guideline for future experiments with trapped atomic Bose- Fermi mixtures in optical lattices
"In spite of ever-increasing research into natural hazards, the reported damage from natural disasters continues to rise, increasingly disrupting human activities. We, as scientists who study the way in which the part of Earth most relevant to society- the surface-behaves, are disturbed and frustrated by this trend. It appears that the large amounts of funding devoted each year to research into reducing the impacts of natural disasters could be much more effective in producing useful results. At the same time we are aware that society, as represented by its decision makers, while increasingly concerned at the impacts of natural disasters on lives and economies, is reluctant to acknowledge the intrinsic activity of Earth's surface and to take steps to adapt societal behaviour to minimise the impacts of natural disasters. Understanding and managing natural hazards and disasters are beyond matters of applied earth science, and also involve considering human societal, economic and political decisions"

Hyperidentities and clones
(2000)
The theory of hyperidentities generalises the equational theory of universal algebras and is applicable in several fields of science, especially in computer sciences. This book presents the theory of hyperidentities and its relation to clone identities. The basic concept of hypersubstitution is used to introduce the monoid of hypersubstitutions, hyperidentities, M-hyperidentities, solid and M-solid varieties. This work integrates into a coherent framework many results scattered throughout the literature over the last eighteen years. In addition, the book contains some applications of hyperidentities to the functional completenes problem in multiple-valued logic. The general theory is also extended to partial algberas. The last chapter contains a list of exercises and open problems with suggestions of future work in this area of research.
