Oncologic and Cardiologic PET/CT-Diagnosis : An Interdisciplinary Atlas and Manual

Since 1999/2000 simultaneous imaging of anatomical features and metabolic activities using fused PET and CT images has complemented and in many cases even replaced what was originally done as separate analysis. – Is this a small revolution? – In fact, this new approach can be considered to be without a rival for imaging diagnosis. The complementary efforts of nuclear medicine physicians and radiologists have improved the diagnostic value of PET/CT scans. The successful use of PET/CT in the field of oncology has been documented world-wide, and in cardiology we can take advantage of the significant findings of PET diagnosis, particularly in the USA. New prospects are now available for paediatric oncology and molecular medicine.

Oil and Security : A World Beyond Petroleum

This book examines the economic impact of changes in the global demand and supply for fossil fuels both on the major producers in Middle Eastern countries around the Persian Gulf, other producers, as well as the world at large. The economic, social and political life of most countries is not only intimately linked to and influenced by the energy market but also affected by historical developments. Among other issues, it shows how the economic, social and political development of societies in Arabia, the peoples of the Arab Peninsula are influenced by their historic and cultural environment, and what the future may bring to this region when their principal economic assets, petroleum and gas, start to lose markets as alternative sources of fossil fuel, alternative, and renewable energy supply the bulk of global energy needs. It also describes how changing fossil fuel costs, access, security of supply, and environmental impacts may affect future economic, social, and political developments as well as technological advances and changes in priorities.

Obstructions in Security-Aware Business Processes : Analysis, Detection, and Handling

This book explores the dilemma-like stalemate between security and regulatory compliance in business processes on the one hand and business continuity and governance on the other. The growing number of regulations, e.g., on information security, data protection, or privacy, implemented in increasingly digitized businesses can have an obstructive effect on the automated execution of business processes. Such security-related obstructions can particularly occur when an access control-based implementation of regulations blocks the execution of business processes. By handling obstructions, security in business processes is supposed to be improved. For this, the book presents a framework that allows the comprehensive analysis, detection, and handling of obstructions in a security-sensitive way. Thereby, methods based on common organizational security policies, process models, and logs are proposed. The Petri net-based modeling and related semantic and language-based research, as well as the analysis of event data and machine learning methods finally lead to the development of algorithms and experiments that can detect and resolve obstructions and are reproducible with the provided software.

Number Story : From Counting to Cryptography

Numbers have fascinated people for centuries. They are familiar to everyone, forming a central pillar of our understanding of the world, yet the number system was not presented to us "gift-wrapped" but, rather, was developed over millennia. Today, despite all this development, it remains true that a child may ask a question about numbers that no one can answer. Many unsolved problems surrounding number matters appear as quirky oddities of little account while others are holding up fundamental progress in mainstream mathematics.

Novel Developments for Sustainable Hydropower

This book presents (selected) new and innovative developments for sustainable and fish-friendly hydropower. It offers unique insights into the challenges, practices and policies of hydropower developments across 8 European countries, providing examples from on-site studies and European-wide analyses. The case studies throughout the book are practical “real-world” examples, which are intended to serve as inspiration for anyone who would like to know more about how solutions for more sustainable hydropower production can be designed and implemented. Hydropower is an important renewable energy source, which, however, can also impact aquatic ecosystems, fish populations and hydro-morphology. EU and national water, environmental and energy legislation strive for sustainable energy and water resource management as well as the protection of important habitats and species. These have an effect on the requirements and decision making processes for hydropower planning, commissioning and operation. With a high variety of measures existing and site-specific conditions as well as national and EU level legal requirements to consider, it can be difficult to determine, what issues to address and which measures to implement.

Norwegian Shipping in the 20th Century : Norway's Successful Navigation of the World's Most Global Industry

This open access book discusses how Norwegian shipping companies played a crucial role in global shipping markets in the 20th century, at times transporting more than ten per cent of world seaborne trade. Chapters explore how Norway managed to remain competitive, despite being a high labour-cost country in an industry with global competition. Among the features that are emphasised are market developments, business strategies and political decisions The Norwegian experience was shaped by the main breaking points in 20th century world history, such as the two world wars, and by long-term trends, such as globalization and liberalization. The shipping companies introduced technological and organizational innovations to build or maintain a competitive advantage in a rapidly changing world. The growing importance of offshore petroleum exploration in the North Sea from the 1970s was both a threat and an opportunity to the shipping companies. By adapting both business strategies and the political regime to the new circumstances, the Norwegian shipping sector managed to maintain a leading position internationally.

Nonbayesian Decision Theory : Beliefs and Desires as Reasons for Action

This book aims to present an account of rational choice from a non-Bayesian point of view. Rational agents maximize subjective expected utility, but contrary to what is claimed by Bayesians, the author argues that utility and subjective probability should not be defined in terms of preferences over uncertain prospects. To some extent, the author’s non-Bayesian view gives a modern account of what decision theory could have been like, had decision theorists not entered the Bayesian path discovered by Ramsey, Savage, and Jeffrey. The author argues that traditional Bayesian decision theory is unavailing from an action-guiding perspective. For the deliberating Bayesian agent, the output of decision theory is not a set of preferences over alternative acts - these preferences are on the contrary used as input to the theory.
