Whether you’re an intermediate-level Python programmer or a student of computational modeling, you’ll delve into examples of complex systems through a series of exercises, case studies, and easy-to-understand explanations. You’ll work with graphs, algorithm analysis, scale-free networks, and cellular automata, using advanced features that make Python such a powerful language. Ideal as a text for courses on Python programming and algorithms, Think Complexity will also help self-learners gain valuable experience with topics and ideas they might not encounter otherwise. Work with NumPy arrays and SciPy methods, basic signal processing and Fast Fourier Transform, and hash tables Study abstract models of complex physical systems, including power laws, fractals and pink noise, and Turing machines Get starter code and solutions to help you re-implement and extend original experiments in complexity Explore the philosophy of science, including the nature of scientific laws, theory choice, realism and instrumentalism, and other topics Examine case studies of complex systems submitted by students and readers
Climate and anthropogenic changes impact the conditions of erosion and sediment transport in rivers. Rainfall variability and, in many places, the increase of rainfall intensity have a direct impact on rainfall erosivity. Increasing changes in demography have led to the acceleration of land cover changes in natural areas, as well as in cultivated areas, and, sometimes, in degraded areas and desertified landscapes. These anthropogenized landscapes are more sensitive to erosion. On the other hand, the increase in the number of dams in watersheds traps a great portion of sediment fluxes, which do not reach the sea in the same amount, nor at the same quality, with consequences on coastal geomorphodynamics. This book is dedicated to studies on sediment fluxes from continental areas to coastal areas, as well as observation, modeling, and impact analysis at different scales from watershed slopes to the outputs of large river basins. This book is concentrated on a number of keywords: “erosion” and “sediment transport”, “model” and “practice”, and “change”. The keywords are briefly discussed with respect to the relevant literature. The contributions in this book address observations and models based on laboratory and field data, allowing researchers to make use of such resources in practice under changing conditions.
This concise reference book provides an international standard for pathologists and oncologists and will serve as an indispensable guide for use in the design of studies monitoring response to therapy and clinical outcome. Diagnostic criteria, pathological features, and associated genetic alterations are described in a strictly disease-oriented manner. Sections on all WHO-recognized neoplasms and their variants include new ICD-O codes, incidence, age and sex distribution, location, clinical signs and symptoms, pathology, genetics, and predictive factors. This volume covers tumours of the nasal cavity and paranasal sinuses, of the nasopharynx, of the hypophyranyx, larynx and trachea, of the oral cavity and oropharynx, of salivary glands, as well as odontogenetic tumours, tumours of the ear, the paraganglionic system, and inherited tumour syndromes. Each entity is extensively discussed with information on clinicopathological, epidemiological, immunophenotypic and genetic aspects of these diseases.
The clothing sector has traditionally been a gateway to export diversification and industrial development for low-income countries (LICs) due to its low fix costs, relatively simple technology, and labor-intensive nature. It has served to absorb large numbers of unskilled, and mostly female, workers and build capital and know-how for more technologically advanced activities within and across sectors. But the environment for global clothing trade has changed significantly which may condition the role the sector can play in promoting export diversification and industrial development in LICs today. Main drivers have been the rise of global buyers and their global sourcing strategies, the phase out of quotas in the Multi-Fiber Arrangement (MFA), and, more recently, the global economic crisis. In the context of these changes, this study analyzes how the clothing sector can still provide a gateway to export diversification and industrial development for LICs today. The key objectives of this study are to assess main developments in the global clothing sector associated with the Multi-Fiber Arrangement (MFA) phase out, global buyers and their sourcing strategies, and the global economic crisis; analyze challenges that LICs are facing in the post-quota and post-crisis world in entering and upgrading within global clothing value chains; and identify policy recommendations to increase the competitiveness of LIC clothing exporters as well as to further their integration into and improve their positions within global clothing value chains. For the study interviews with buyers in the US, the EU and South Africa as well as case studies in Sub-Saharan African LICs (Kenya, Lesotho and Swaziland), Cambodia and Bangladesh were conducted. The study finds that global consolidation in the clothing sector has increased entry barriers at the country and firm level. This has created new challenges to LIC suppliers as low labor costs and preferential market access are not enough to be competitive in the clothing sector today. Suppliers with broad capabilities have been able to develop strategic relationships with global buyers. Marginal or new suppliers are entering the global value chains through intermediaries, but face limited upgrading opportunities. FDI plays an important role in integrated LICs into global clothing value chains, yet it needs to be used in a way that promotes and upgrades local clothing industries. Overall, the clothing sector still provides opportunities for export diversification and industrial development. However, this requires pro-active policies to increase the competitiveness and local embeddedness of LIC clothing exporters.
The potential for using fusion energy to produce commercial electric power was first explored in the 1950s. Harnessing fusion energy offers the prospect of a nearly carbon-free energy source with a virtually unlimited supply of fuel. Unlike nuclear fission plants, appropriately designed fusion power plants would not produce the large amounts of high-level nuclear waste that requires long-term disposal. Due to these prospects, many nations have initiated research and development (R&D) programs aimed at developing fusion as an energy source. Two R&D approaches are being explored: magnetic fusion energy (MFE) and inertial fusion energy (IFE). An Assessment of the Prospects for Inertial Fusion Energy describes and assesses the current status of IFE research in the United States; compares the various technical approaches to IFE; and identifies the scientific and engineering challenges associated with developing inertial confinement fusion (ICF) in particular as an energy source. It also provides guidance on an R&D roadmap at the conceptual level for a national program focusing on the design and construction of an inertial fusion energy demonstration plant.
The essential characteristic of a dynamic graphical method is the direct manipulation of elements of a graph on a computer screen, which in high-performance implementations, the elements change virtually instantaneously on the screen. This book contains a collection of papers about dynamic graphics dating from the late 1960s to 1988. Although technology has advanced considerably, the fundamental ideas about basic graphical principles and data-analytic goals are still relevant today.
This book focuses on the most recent, relevant, comprehensive and significant aspects in the well-established multidisciplinary field Laboratory Astrophysics. It focuses on astrophysical environments, which include asteroids, comets, the interstellar medium, and circumstellar and circumplanetary regions. Its scope lies between physics and chemistry, since it explores physical properties of the gas, ice, and dust present in those systems, as well as chemical reactions occurring in the gas phase, the bare dust surface, or in the ice bulk and its surface. Each chapter provides the necessary mathematical background to understand the subject, followed by a case study of the corresponding system. The book provides adequate material to help interpret the observations, or the computer models of astrophysical environments. It introduces and describes the use of spectroscopic tools for laboratory astrophysics. This book is mainly addressed to PhD graduates working in this field or observers and modelers searching for information on ice and dust processes.
