Аннотация
The essential resource that offers a comprehensive understanding of OLED optimizations Highly Efficient OLEDs. Materials Based on Thermally Activated Delayed Fluorescence (TADF) offers substantial information on the working principle of OLEDs and on new types of emitting materials (organic and inorganic). As the authors explain, OLEDs that use the Singlet-Harvesting mechanism based on the molecular property of TADF work according to a new exciton harvesting principle. Thus, low-cost emitter materials, such as Cu(I) or Ag(I) complexes as well as metal-free organic molecules, have the potential to replace high-cost rare metal complexes being currently applied in OLED technology. With contributions from an international panel of experts on the topic, the text shows how the application of new TADF materials allow for the development of efficient OLED displays and lighting systems. This new mechanism is the gateway to the third-generation of luminescent materials. This important resource: Offers a state-of-the-art compilation of the latest results in the dynamically developing field of OLED materials Is edited by a pioneer in the field of OLED material technology Contains a detailed application-oriented guide to new low-cost materials for displays and lighting Puts the focus on the emerging fields of OLED technology Written for materials scientists, solid state chemists, solid state physicists, and electronics engineers, Highly Efficient OLEDs. Materials Based on Thermally Activated Delayed Fluorescence offers a comprehensive resource to the latest advances of OLEDs based on new TADF materials.

Learn from a master of quantitative finance the rules that made him a success. The UnRules presents the dynamic rules for success in the age of exponential information. Written by Igor Tulchinsky, the trader behind global quantitative investment management firm WorldQuant, this book is more than just another Big Data guide for financial wonks – it’s a prescriptive, inspirational book for everyone navigating the tidal waves of the information age. Data is everywhere, coming at us in a never-ceasing, ever-rising river that threatens to overwhelm us. Tulchinsky shows us, however, how natural patterns underlie that data – patterns that may dictate life or death, success or failure. The marriage of man and machines has allowed scientists to explore increasingly complex worlds, to predict outcomes and eventualities. This book demonstrates how to exercise real intelligence by discerning the patterns that surround us every day and how to leverage this information into success in the workplace and beyond. Igor Tulchinsky has spent his career discerning meaningful patterns in information. For decades, Tulchinsky has been at the forefront of developing predictive trading algorithms known as alphas – a quest that has led Tulchinsky to explore the nature of markets, the fundamentals of risk and reward, and the science behind complex nonlinear systems. Tulchinsky explains what we know of these systems, both natural and man-made, in accessible and personal terms, and he shares how alphas have driven his success as an investor and shaped his central “UnRule,” which is that no rule applies in every case. As markets evolve, even the most effective trading algorithms weaken over time. Decades of creating successful alphas – and learning how to effectively transform them into strategies – have taught Tulchinsky about the need to combine flexibility and focus, discipline and creativity when building complex models. At a time when data and computing power are exploding exponentially, The UnRules provides an expert introduction to our increasingly quantitative world.

Social Structures and Natural Systems. Is a Scientific Assemblage Workable? - Georges Guille-Escuret
Аннотация
Trapped between the caricatured causalities of biological determinism and the sinister abdications of sociological relativism, socio-ecological interdisciplinarity stagnates. It has lost sight of the ambition of a long-term program and no longer works to conduct applied research on the concrete prerequisites for reliable cooperation, despite an accumulation of emergencies. The difficulty lies in the general and prolonged abandonment of necessary procedures under the influence of hidden philosophical presumptions. In the end, ecology, sociology, history, economics, agronomy, etc. are seriously handicapped by the absence of a common epistemology of comparative practice, an absence maintained by the dominant epistemology itself. Social Structures and Natural Systems seeks to demonstrate, with regard to social anthropology and ecology, a scientific compatibility of research subject to methodological requirements that are deductible from the conditions of the existence of science itself. All of this boils down to one observation: this book will be a success if, and only if, it becomes a beginning.

The investment landscape has changed dramatically over the last few years, destroying many of the old certainties by which investors lived their lives. In particular, it has shaken belief in the ability of traditional asset types such as bonds and equities to protect them from abnormal market conditions, and it has brought home how closely correlation between different markets can be squeezed together by extreme pressure. Future investors will have to regard so-called «alternative» assets as essential elements within their portfolios, and be prepared to deal with the complexities that this will entail. This will in turn force a re-appraisal of core concepts such as «risk» and «return», not least because some alternative asset classes do not lend themselves well to traditional return measures. Exciting times lie ahead, but a thorough working knowledge of the various alternative asset classes will be an essential pre-requisite to success, and perhaps even to survival. Alternative Assets meets investor's need for a guide on where to allocate in this new climate. It provides investors with a primer on each alternative asset class, as well as practical tips on the pros and cons, implementation, returns analysis, fees and costs. It also offers introductory guidance on how to set investment targets, and how alternative assets can be accommodated within the allocation process. Each chapter gives useful background knowledge on a particular asset type, including a discussion of whether a satisfactory beta return level exists and, if so, the different ways in which it might be accessed. Written by best-selling author Guy Fraser-Sampson, this book guides investors through the new look alternative investment arena, providing post-financial crisis perspective and investment advice on the alternatives landscape.

The Book The behaviour of helicopters and tiltrotor aircraft is so complex that understanding the physical mechanisms at work in trim, stability and response, and thus the prediction of Flying Qualities, requires a framework of analytical and numerical modelling and simulation. Good Flying Qualities are vital for ensuring that mission performance is achievable with safety and, in the first and second editions of Helicopter Flight Dynamics, a comprehensive treatment of design criteria was presented, relating to both normal and degraded Flying Qualities. Fully embracing the consequences of Degraded Flying Qualities during the design phase will contribute positively to safety. In this third edition, two new Chapters are included. Chapter 9 takes the reader on a journey from the origins of the story of Flying Qualities, tracing key contributions to the developing maturity and to the current position. Chapter 10 provides a comprehensive treatment of the Flight Dynamics of tiltrotor aircraft; informed by research activities and the limited data on operational aircraft. Many of the unique behavioural characteristics of tiltrotors are revealed for the first time in this book. The accurate prediction and assessment of Flying Qualities draws on the modelling and simulation discipline on the one hand and testing practice on the other. Checking predictions in flight requires clearly defined mission tasks, derived from realistic performance requirements. High fidelity simulations also form the basis for the design of stability and control augmentation systems, essential for conferring Level 1 Flying Qualities. The integrated description of flight dynamic modelling, simulation and flying qualities of rotorcraft forms the subject of this book, which will be of interest to engineers practising and honing their skills in research laboratories, academia and manufacturing industries, test pilots and flight test engineers, and as a reference for graduate and postgraduate students in aerospace engineering.

When there are too many choices, there is no choice. The choices are entangled in a maze of rather confused possibilities. They go through many nebulous paths. Doubt, hesitation, indecision, become the only resolutions possible. Choosing is the anxiety of being wrong! The brand, the quality / price ratio, the aesthetics … give confidence, but often with naivety! There is a gap between the reality of the qualities of the products and the perception of the customer. These are prejudices, illusions, a lack of knowledge … Generally speaking, is the consumer-client able to appreciate, by sight, by touch, or even by a brief trial of operation, all the strengths and weaknesses? a lot of products? Market value dominates the use value. Marketing will discover that we must no longer confuse the consumer (the customer) and the user. The economic system only works because consumers are in the opacity of their choices. The search for technical prowess and above all market value has dominated the search for value in use.

Digital Rebirth transcends digital transformation. It involves a revolutionary reinventing of the purpose, nature and processes of a company, with accompanying digital business and technological platforms. This book presents a clear framework for practical digital rebirth of companies, contrasting it to prevalent «digital transformation» approaches. Aimed at large and medium-sized companies, as well as their subcontractors and service providers, but also at budding entrepreneurs, it should be read and used by company boards, executives, managers, startup leaders and business consultants.. – In every section of the book you will find proven concepts of Digital Rebirth, digital reinvention, collaborative digital practices, combinatorial technologies, digital platforms, digital ecosystems and pointers how to move from obsolete mindsets and left-over baggage to reinvented digitalization minds and processes. – It shows clearly how some major companies have digitally rebirthed themselves – or are in the process of it – to be or to become a leading player in the digital economy. – Company (and industry) illustrations are accompanied by descriptions of Digital Rebirth approaches, methodologies and practical tools. – The book's content is ideal for use in company workshops and executive sessions, as well as business leadership mindset sessions, and has been validated in such activities by the authors, including boards of highly renowned companies on all continents. – At the end of the book, the unique approach of Digital Rebirth is condensed into a framework of five digital drivers, to assist in the right activities for purposeful and successful company rebirth. The concept of Digital Rebirth shows clearly that, in the light of recent developments like Internet of Things, Artificial Intelligence, Industry 4.0 and Cloud-based Services, well-established traditional industry and competitive models are not any longer satisfactory to understanding and dealing with digital realities.
