It concludes with a discussion of the practical relevance and future of international and comparative studies in LIS. See a short interview with Peter Lor on his work https://www.ifla.org/node/92590
Drawing on the most current research, this study is the perfect companion for those who work alongside elderly people with and without dementia. The book explains why changes in cognition, motor skills, and pain are typical for the elderly while describing the most prevalent subtypes of dementia, including Alzheimer's disease, vascular dementia, and frontotemporal dementia. Focusing on the motor skills of hand motor activity and gait, the study also illustrates changes in the various aspects of pain experience, explaining them clearly through the use of neuropathology of the medial and lateral pain systems. Updates concerning compensation and rehabilitation are also included.
A corrective to the contemporary idea that Buddhism has always been an environmentally friendly religion In the current popular imagination, Buddhism is often understood to be a religion intrinsically concerned with the environment. The Dharma, the name given to Buddhist teachings by Buddhists, states that all things are interconnected. Therefore, Buddhists are perceived as extending compassion beyond people and animals to include plants and the earth itself out of a concern for the total living environment. In The Buddha's Footprint, Johan Elverskog contends that only by jettisoning this contemporary image of Buddhism as a purely ascetic and apolitical tradition of contemplation can we see the true nature of the Dharma. According to Elverskog, Buddhism is, in fact, an expansive religious and political system premised on generating wealth through the exploitation of natural resources. Elverskog surveys the expansion of Buddhism across Asia in the period between 500 BCE and 1500 CE, when Buddhist institutions were built from Iran and Azerbaijan in the west, to Kazakhstan and Siberia in the north, Japan in the east, and Sri Lanka and Indonesia in the south. He examines the prosperity theology at the heart of the Dharma that declared riches to be a sign of good karma and the means by which spritiual status could be elevated through donations bequeathed to Buddhist institutions. He demonstrates how this scriptural tradition propelled Buddhists to seek wealth and power across Asia and to exploit both the people and the environment. Elverskog shows the ways in which Buddhist expansion not only entailed the displacement of local gods and myths with those of the Dharma—as was the case with Christianity and Islam—but also involved fundamentally transforming earlier social and political structures and networks of economic exchange. The Buddha's Footprint argues that the institutionalization of the Dharma was intimately connected to agricultural expansion, resource extraction, deforestation, urbanization, and the monumentalization of Buddhism itself.

Furthering the aim of reducing human exposure to hazardous environments, this monograph presents a detailed study of the modeling and control of vehicle-manipulator systems. The text shows how complex interactions can be performed at remote locations using systems that combine the manipulability of robotic manipulators with the ability of mobile robots to locomote over large areas. The first part studies the kinematics and dynamics of rigid bodies and standard robotic manipulators and can be used as an introduction to robotics focussing on robust mathematical modeling. The monograph then moves on to study vehicle-manipulator systems in great detail with emphasis on combining two different configuration spaces in a mathematically sound way. Robustness of these systems is extremely important and Modeling and Control of Vehicle-manipulator Systems effectively represents the dynamic equations using a mathematically robust framework. Several tools from Lie theory and differential geometry are used to obtain globally valid representations of the dynamic equations of vehicle-manipulator systems. The specific characteristics of several different types of vehicle-manipulator systems are included and the various application areas of these systems are discussed in detail. For underwater robots buoyancy and gravity, drag forces, added mass properties, and ocean currents are considered. For space robotics the effects of free fall environments and the strong dynamic coupling between the spacecraft and the manipulator are discussed. For wheeled robots wheel kinematics and non-holonomic motion is treated, and finally the inertial forces are included for robots mounted on a forced moving base. Modeling and Control of Vehicle-manipulator Systems will be of interest to researchers and engineers studying and working on many applications of robotics: underwater, space, personal assistance, and mobile manipulation in general, all of which have similarities in the equations required for modeling and control.
This book represents views, frameworks and practices on stimulating and realising our optimal potential as human beings in the context of a workplace where there is a desire to achieve shared goals and aspirations in order to accomplish positive economic, societal and environmental impacts and outcomes. It describes a vision of how life and work in organisations could be. We describe a new kind of organisation. Being a good person and doing good things while making profit are a real possibility for those management innovators who think beyond immediate trade-offs. In this book we explore management innovation as core study field and arena for re-inventing and re-imagining how people in organisations could execute management activities such as planning, organising, leading and controlling for multiple stakeholder satisfaction and benefits. Work can be much more joyful and fulfilling than we think, but it requires courage from us to take responsibility when freedom is offered.
This book analyses the ideology that China's leader Xi Jinping has crafted during his decade in power. China’s political system and domestic and foreign policies have, between 2012 and 2022, become more defined by the political thought of Xi Jinping, the most powerful leader of the Chinese Communist Party since the time of Mao Zedong. Today, Xi’s China is embroiled in superpower rivalry with the United States and its allies. Therefore, ongoing ideological transformation in the People’s Republic is destined to have global repercussions. Yet surprisingly, the ideological mission of Xi Jinping is poorly understood. Based on analysis of Xi Jinping’s collected speeches, the book argues that China’s new state ideology is constructed around the three key concepts of loyalty, discipline, and greatness. Xi’s mission is about ideological re-orientation and re-activation, as well as organizational innovation, seeking to frame China’s “national self” as a collective unit under one political banner and one leader. However, despite the monumental Party-state effort to boost the new ideology and state-scripted “moral careers”, the book contends that Xi Jinping cannot take for granted that political and patriotic loyalty will forever trump the formation of “disloyal moral careers” in society.
The reason to perform calculations in material science usually falls into one of two categories: to predict or explain the origin of material properties. This thesis covers first-principle calculations for solids at extreme conditions, from both of the two mentioned categories. I primarily have studied the effects of high-pressure and high-temperature on lattice dynamics, mechanical and electronic properties. To treat the effects of temperature, ab initio molecular dynamics (AIMD) simulations and self-consistent phonon calculations, based on density functional theory, have been utilised. These approaches account for the temperature effects by considering thermally excited supercells as samples of a statistical ensemble. To extract properties from this representation, I have used methods which maps the supercell data to a unit cell representation or fits it to a simple model Hamiltonian. The small displacement method was used to analyse the dynamical stability for nitrides and polymorphs of silica, synthesised at high-pressure in a diamond anvil cell. The nitride compounds consist of a high amount of nitrogen either as chains, forming a porous framework together with transition metal atoms or as dinitrogen molecules, occupying the channels of the framework. The nitrogen chains consist of single- or double-bonded nitrogen atoms, making these compounds highly energetic. Polymorphs of silica can be used to model deep Earth liquids. These new polymorphs, named coesite-IV and coesite-V, consist of four-, five-, and six-oriented silicon. Some of the octahedra of the six-oriented silicon atoms, of these new phases, are sharing faces, which according to Pauling's third rule would make them highly unstable. My phonon calculations indicate these phases to be dynamically stable. Furthermore, my calculations predict higher compressibility for these new phases compared to the competing ones. By modelling silicate melts with coesite-IV and coesite-V, a more complex and compressible structure is expected, affecting the predicted seismic behaviour. I studied Kohn anomalies for body-centered cubic niobium by simulating this material with self-consistent phonon calculations. The electronic structure was studied by using a band unfolding technique, for which I obtained an effective unit cell representation of the electronic structure at elevated temperatures. Temperature primarily smeared the electronic states but did not induce significant shifts of the bands. In parallel, the anharmonicity of this system was studied using the temperature dependent effective potential method. Even close to the melting temperature, this element is remarkably harmonic. The experimentally observed disappearance of the Kohn anomalies with increased temperature is predominantly dependent, according to my calculations, on the temperature-induced smearing of the electronic states. Using stress-strain relations, accurate high-temperature elastic properties were predicted for Ti0.5Al0.5N. The simulations were performed with AIMD. The stresses were fitted using the least-squares method to a linear expression from which the elastic constants were derived. The results were compared with previously performed calculations that employed additional approximations. The results of the symmetry imposed force constant temperature dependent effective potential (SIFC-TDEP) method agrees well with our results. I also compared my results with TiN calculations that employed a similar methodology. My and the SIFC-TDEP results are reporting lower values for the polycrystalline moduli than the calculations for TiN. The data I generated were also used for a machine learned interatomic potential method, where moment tensor potentials were trained and evaluated, using this data. Den här avhandlingen handlar om beräkningar för material. När materialberäkningar utförs är det antingen för att förutsäga eller förklara egenskaper. De beräkningar som jag har gjort i denna avhandling är baserade på fundamentala fysiska lagar. Detta betyder att de är rent baserade på teori, och inte har anpassats efter resultat av experiment. Jag har i mitt arbete använt mig mycket utav en teori som kallas gitter dynamik. Den är definierad för periodiska material, det vill säga att atomerna i dessa material upprepas i periodiska mönster. Vi kan då anta att det finns en jämviktspunkt för alla atomerna, som de vibrerar omkring. Dessa vibrationer kan beskrivas som om atomerna påverkar varandra med fiktiva fjädrar. Genom att beräkna styrkan för dessa fjädrar kan vi beskriva vibrationerna av atomerna. Dessa vibrationer i sin tur är avgörande för materialets egenskaper. För att beskriva ett material vid en specifik temperatur har jag använt mig utav olika metoder för att simulera det. En simulering kan ses som ett “dator experiment”. Problemet är dock hur vi ska mäta egenskaperna i simuleringen. Ju större och mera komplex en simulering är, desto svårare blir det att beräkna egenskaperna av det simulerade materialet. Vi hamnar i en situation likt den vi skulle befinna oss om vi hade gjort ett experiment i verkligheten, och tvingas använda förenklade modeler för att kunna tolka resultatet. Jag har därför använt mig utav metoder för att utvinna vibrationer av atomer, elektrontillstånd eller elastiska egenskaper, specifikt utvecklade för att användas på denna typ utav simuleringar. Mitt arbete har kretsat kring hur dessa egenskaper påverkas av extrema temperaturer och tryck. De beräkningar jag har utfört vid höga tryck har varit för nyupptäckta nitrider och faser av kiseldioxid. Nitriderna är porösa material som innehåller en stor mängd kväve. Det höga kväveinehållet gör så att det lagras en stor mängd kemisk energi i enkel- och dubbelbindningar mellan kväveatomerna. De nya faserna av kiseldioxid har en betydelse för vår förståelse av jordens inre. Deras existens öppnar upp för att det kan finnas mera komplexa och ihoptryckbara flytande material, under jordens nedre mantel, än vad tidigare har varit antaget. Mina beräkningar har bekräftat strukturerna för dessa nyupptäckta material. Vid höga temperaturer har jag studerat för metallen niob hur vibrationerna av atomerna är relaterade till olika elektrontillstånd. För specifika vibrationer ökar frekvensen med ökad temperatur. Detta är något ovanligt eftersom vibrationernas frekvenser vanligtvis brukar minska med ökad temperatur. Mina simulering för denna metal överensstämmer med resultat från experiment. Orsaken till varför visa vibrationers frekvenser ökar kan jag förklara med att elektrontillståndens enskilda energier varierar över tid på grund av den ökade temperaturen. Jag har även använt mig av simuleringar för att beräkna elastiska egenskaper av legeringen Ti0.5Al0.5N. Ti1?xAlxN legeringar används som beläggningar på skärverktyg som används för metall. För att öka effektiviteten av beläggningen, behövs det detaljerad kunskap av dess mekaniska egenskaper för den temperatur som de används vid. Jag beräknade därför så noggrant som möjligt de elastiska egenskaperna för Ti0.5Al0.5N. Dessa beräkningar är avsedda för att användas som en referens för andra beräkningsmässigt billigare metoder. Datan som genererades från mina simuleringar användes även för en sådan metod, baserad på maskininlärning.
This book examines the distribution and interpretation of anaphors and pronouns. Through a detailed analysis of simplex and complex anaphors in Dutch and English, as well as other Romance and Germanic languages, the authors show that the relationship between an anaphor and its antecedent can be captured in terms of general Minimalist principles.
A comprehensive examination of the interfaces of logic, computer science, and game theory, drawing on twenty years of research on logic and games. This book draws on ideas from philosophical logic, computational logic, multi-agent systems, and game theory to offer a comprehensive account of logic and games viewed in two complementary ways. It examines the logic of games: the development of sophisticated modern dynamic logics that model information flow, communication, and interactive structures in games. It also examines logic as games: the idea that logical activities of reasoning and many related tasks can be viewed in the form of games. In doing so, the book takes up the “intelligent interaction” of agents engaging in competitive or cooperative activities and examines the patterns of strategic behavior that arise. It develops modern logical systems that can analyze information-driven changes in players' knowledge and beliefs, and introduces the “Theory of Play” that emerges from the combination of logic and game theory. This results in a new view of logic itself as an interactive rational activity based on reasoning, perception, and communication that has particular relevance for games. Logic in Games, based on a course taught by the author at Stanford University, the University of Amsterdam, and elsewhere, can be used in advanced seminars and as a resource for researchers.
This book develops a view of logic as a theory of information-driven agency and intelligent interaction between many agents - with conversation, argumentation and games as guiding examples. It provides one uniform account of dynamic logics for acts of inference, observation, questions and communication, that can handle both update of knowledge and revision of beliefs. It then extends the dynamic style of analysis to include changing preferences and goals, temporal processes, group action and strategic interaction in games. Throughout, the book develops a mathematical theory unifying all these systems, and positioning them at the interface of logic, philosophy, computer science and game theory. A series of further chapters explores repercussions of the 'dynamic stance' for these areas, as well as cognitive science.
The world's human population now constitutes the largest driving force of changes to the biosphere. Emerging water challenges require new ideas for governance and management of water resources in the context of rapid global change. This book presents a new approach to water resources, addressing global sustainability and focusing on socio-ecological resilience to changes. Topics covered include the risks of unexpected change, human impacts and dependence on global water, the prospects for feeding the world's population by 2050, and a pathway for the future. The book's innovative and integrated approach links green and blue freshwater with terrestrial and aquatic ecosystem functions and use. It also links changes arising from land-use alteration with the impacts of those changes on social-ecological systems and ecosystem services. This is an important, state-of-the-art resource for academic researchers and water resource professionals, and a key reference for graduate students studying water resource governance and management.
The Free and Open Source Software (FOSS) movement demonstrates how labour can self-organise production, and, as is shown by the free operating system GNU/Linux, even compete with some of the worlds largest firms. The book examines the hopes of such thinkers as Friedrich Schiller, Karl Marx, Herbert Marcuse and Antonio Negri, in the light of the recent achievements of the hacker movement. This book is the first to examine a different kind of political activism that consists in the development of technology from below.

What are the different muscarinic acetylcholine receptor subtypes and how are they distributed in the airways and molecular signalling mechanisms? What is their function in neurogenic and non-neurogenic control of the airways and in inflammatory mechanisms? How is their gene expression regulated? The great importance of muscarinic acetylcholine receptors for the pathophysiology and treatment of chronic inflammatory obstructive airways diseases calls for a comprehensive and integrated overview of the current knowledge to address such questions, to discuss the role of these receptor subtypes in diseases such as asthma and COPD, and to present novel perspectives on antimuscarinic drug development. The present book is the worthy result of this need. It points out innovative insights into the hitherto poorly understood role of postjunctional muscarinic M2 receptors in airway smooth muscle contraction and sheds some light on the novel concepts of antimuscarinic drug development, with special reference to the l

The first full-fledged critical edition and historical study of the Erdeni Tunumal Sudur, the Mongolian history of Altan Khan and his descendants, offering a full-range English-written historical and literary evaluation of this unique and fairly reliable, but long neglected discovery in Mongolian studies. With transcription, word index and English translation, as well as extensive commentary on the historical events of Altan Khan’s reign, especially the 1550 attack on Beijing, the 1571 peace accord with the Ming, and the 1578 meeting with the Dalai Lama and the subsequent Buddhist conversion. In particular, the author shows how Altan Khan’s reformulation of the boundaries of Dayan Khan’s Mongol nation and state catalyzed the political fragmentation of the Mongols with dire consequences in relation to the rising Manchu state. Vital for a better understanding of Mongol history during the late Ming.
Over the past decades, large amounts of data about carabids have been collected in the Netherlands, initially for the purpose of creating distribution maps for the country. In addition to information from collections and faunistic publications, a significant amount of data came from ecological studies using pitfall traps. Because of the rich tradition of carabidological research in the Netherlands, an exceptionally large database of these pitfall data is available. The database is a mix of approximately 1,500 short-term samples and circa 4,400 so-called 'year-samples', for which pitfalls were functional during the whole activity period of ground beetles in spring and autumn. These year-samples came from 2,850 sites, covering the period of 1953-2018, and represent all habitats on the Dutch landscape. These data offer an unusual view of the presence and activity of this common insect family. The data gathered from pitfall trapping is summarised and provides a fresh integrated perspective about the Dutch ground beetle fauna. The characteristic species composition of 17 habitat groups is described in detail. Over 320 species present in the database have been classified into six main groups, according to their patterns of habitat use. Both the classification of habitats and associated species have been tested and used in various analyses in the book. Two chapters give special attention to changes in the Dutch fauna over the past 66 years by means of extensive trend analysis and relate this understanding to nature conservation. The book provides an extension and update for Turin's (2000) atlas. The Dutch carabid fauna is discussed considering relevant literature but uses predominantly European studies to put the faunal patterns in broader context. This book presents the story of Dutch ground beetles and illustrates the contribution of pitfall trapping to our understanding of the ecology of this fascinating and unusually well-studied group of beetles.
In the contemporary world the meeting of Buddhism and Islam is most often imagined as one of violent confrontation. Indeed, the Taliban's destruction of the Bamiyan Buddhas in 2001 seemed not only to reenact the infamous Muslim destruction of Nalanda monastery in the thirteenth century but also to reaffirm the stereotypes of Buddhism as a peaceful, rational philosophy and Islam as an inherently violent and irrational religion. But if Buddhist-Muslim history was simply repeated instances of Muslim militants attacking representations of the Buddha, how had the Bamiyan Buddha statues survived thirteen hundred years of Muslim rule? Buddhism and Islam on the Silk Road demonstrates that the history of Buddhist-Muslim interaction is much richer and more complex than many assume. This groundbreaking book covers Inner Asia from the eighth century through the Mongol empire and to the end of the Qing dynasty in the late nineteenth century. By exploring the meetings between Buddhists and Muslims along the Silk Road from Iran to China over more than a millennium, Johan Elverskog reveals that this long encounter was actually one of profound cross-cultural exchange in which two religious traditions were not only enriched but transformed in many ways.
This book is a comprehensive guide to dentomaxillofacial imaging in paediatric dentistry and is an excellent resource for both general dental practitioners and paediatric dentists. Radiation protection, radiation doses and potential risks of ionising radiation are discussed, to provide dentists with appropriate information when they are asked about these important issues in their practice. Technical information about X-ray machines, ranging from the intraoral machine to the medical computed tomography machine, as well as the differences between digital image detectors, are explained to the extend a (pediatric) dentist should know. The latter is important to understand why certain exposure settings are used and what the advantages or disadvantages are of the machines and the image detectors. Non-ionising radiation techniques, magnetic resonance imaging and ultrasonography, are also explained, as well are their applications in the field of dentomaxillofacial radiology. Knowing which imaging technique will provide the best diagnostic images possible, is key to every clinical case a dentist is faced with. A wide range of clinical examples are displayed in this book, ranging from incidental findings to malignant pathology. All are illustrated with radiographic material and explained, in order to give the reader a good sense of what to look for when assessing radiographs in the dentomaxillofacial field
Controlling a system with control and state constraints is one of the most important problems in control theory, but also one of the most challenging. Another important but just as demanding topic is robustness against uncertainties in a controlled system. One of the most successful approaches, both in theory and practice, to control constrained systems is model predictive control (MPC). The basic idea in MPC is to repeatedly solve optimization problems on-line to find an optimal input to the controlled system. In recent years, much effort has been spent to incorporate the robustness problem into this framework. The main part of the thesis revolves around minimax formulations of MPC for uncertain constrained linear discrete-time systems. A minimax strategy in MPC means that worst-case performance with respect to uncertainties is optimized. Unfortunately, many minimax MPC formulations yield intractable optimization problems with exponential complexity. Minimax algorithms for a number of uncertainty models are derived in the thesis. These include systems with bounded external additive disturbances, systems with uncertain gain, and systems described with linear fractional transformations. The central theme in the different algorithms is semidefinite relaxations. This means that the minimax problems are written as uncertain semidefinite programs, and then conservatively approximated using robust optimization theory. The result is an optimization problem with polynomial complexity. The use of semidefinite relaxations enables a framework that allows extensions of the basic algorithms, such as joint minimax control and estimation, and approx- imation of closed-loop minimax MPC using a convex programming framework. Additional topics include development of an efficient optimization algorithm to solve the resulting semidefinite programs and connections between deterministic minimax MPC and stochastic risk-sensitive control. The remaining part of the thesis is devoted to stability issues in MPC for continuous-time nonlinear unconstrained systems. While stability of MPC for un-constrained linear systems essentially is solved with the linear quadratic controller, no such simple solution exists in the nonlinear case. It is shown how tools from modern nonlinear control theory can be used to synthesize finite horizon MPC controllers with guaranteed stability, and more importantly, how some of the tech- nical assumptions in the literature can be dispensed with by using a slightly more complex controller.

The education of engineers is set in the context of engineering practice, that is, Conceiving, Designing, Implementing, and Operating (CDIO) through the entire lifecycle of engineering processes, products, and processes.

Artificial neural networks possess several properties that make them particularly attractive for applications to modelling and control of complex non-linear systems. Among these properties are their universal approximation ability, their parallel network structure and the availability of on- and off-line learning methods for the interconnection weights. However, dynamic models that contain neural network architectures might be highly non-linear and difficult to analyse as a result. Artificial Neural Networks for Modelling and Control of Non-Linear Systems investigates the subject from a system theoretical point of view. However the mathematical theory that is required from the reader is limited to matrix calculus, basic analysis, differential equations and basic linear system theory. No preliminary knowledge of neural networks is explicitly required. The book presents both classical and novel network architectures and learning algorithms for modelling and control. Topics include non-linear system identification, neural optimal control, top-down model based neural control design and stability analysis of neural control systems. A major contribution of this book is to introduce NLq Theory as an extension towards modern control theory, in order to analyze and synthesize non-linear systems that contain linear together with static non-linear operators that satisfy a sector condition: neural state space control systems are an example. Moreover, it turns out that NLq Theory is unifying with respect to many problems arising in neural networks, systems and control. Examples show that complex non-linear systems can be modelled and controlled within NLq theory, including mastering chaos. The didactic flavor of this book makes it suitable for use as a text for a course on Neural Networks. In addition, researchers and designers will find many important new techniques, in particular NLq emTheory, that have applications in control theory, system theory, circuit theory and Time Series Analysis.
China has lived with the Internet for nearly two decades. Will increased Internet use, with new possibilities to share information and discuss news and politics, lead to democracy, or will it to the contrary sustain a nationalist supported authoritarianism that may eventually contest the global information order? This book takes stock of the ongoing tug of war between state power and civil society on and off the Internet, a phenomenon that is fast becoming the centerpiece in the Chinese Communist Party's struggle to stay in power indefinitely. It interrogates the dynamics of this enduring contestation, before democracy, by following how Chinese society travels from getting access to the Internet to our time having the world's largest Internet population. Pursuing the rationale of Internet regulation, the rise of the Chinese blogosphere and citizen journalism, Internet irony, online propaganda, the relation between state and popular nationalism, and finally the role of social media to bring about China's democratization, this book offers a fresh and provocative perspective on the arguable role of media technologies in the process of democratization, by applying social norm theory to illuminate the competition between the Party-state norm and the youth/subaltern norm in Chinese media and society.

Fine Sediment in Open Water is mainly written for professional engineers working in estuaries and coastal systems. It provides the basis for a fundamental understanding of the physical, biological and chemical processes governing the transport and fate of fine sediment in open water and explains how this understanding can steer engineering studies with numerical models. This is a unique treatment of processes at a variety of spatial and temporal scales, from the micro-scale (colloid scale) to system-wide scales, and from intra-tidal time periods to decades.Beginning with the processes governing the transport and fate of fine sediment in shallow open water, the first eight chapters are dedicated to the hydrodynamic, soil mechanics and biological processes which determine fine sediment concentrations in the water column, in/on the bed and the exchange of sediment between bed and water column. The next two chapters treat the net fluxes of fine sediment as a function of asymmetries in forcing and sediment properties. These fundamental processes form the basis for the subsequent chapters on modeling in which the governing equations are presented, and tools are provided to aggregate and parameterize the various processes elaborated in the first eight chapters. Further, any numerical model study should be based on a conceptual model, as illustrated in the final five chapters, which provide examples of numerical modeling studies on the transport and fate of fine sediment in a coastal sea, an estuary, a tidal river, a lake, and around and within a harbor basin.Related Link(s)
