Abstract

The propulsion system behaviour is a key aspect for the overall dynamics of a ship. However, despite its great importance, numerical methodologies for detailed investigations on marine propulsion dynamics are not yet widely covered in scientific literature. This book presents the main steps for the development of a multi-physic simulation platform, able to represent the motions of a twin screw ship in six degrees of freedom, taking into account the whole propulsion system and automation effects. A number of mathematical sub-models had been developed and calibrated by a set of experimental tests, in model and full scale. Finally, the sea trials campaign of a ship is used to validate and tune the developed simulator. The proposed simulation methodology can be used in the ship preliminary design phase, in order to plan and test the propulsion system and automation. Further applications can include the design optimization and crew training.

Abstract

These Proceedings offer a selection of peer-reviewed research and survey papers by some of the foremost international researchers in the fields of finance, energy, stochastics and risk, who present their latest findings on topical problems. The papers cover the areas of stochastic modeling in energy and financial markets; risk management with environmental factors from a stochastic control perspective; and valuation and hedging of derivatives in markets dominated by renewables, all of which further develop the theory of stochastic analysis and mathematical finance. The papers were presented at the first conference on “Stochastics of Environmental and Financial Economics (SEFE)”, being part of the activity in the SEFE research group of the Centre of Advanced Study (CAS) at the Academy of Sciences in Oslo, Norway during the 2014/2015 academic year.

Abstract

Living in a networked world means never really getting to decide in any thoroughgoing way who or what enters your “space” (your laptop, your iPhone, your thermostat…your home). With this as a basic frame-of-reference, James J. Brown’s Ethical Programs examines and explores the rhetorical potential and problems of an hospitality ethos suited to a new era of hosts and guests. Brown reads a range of computational strategies and actors including the general principles underwriting the Transmission Control Protocol (TCP), which determines how packets of information can travel through the internet, to the Obama election campaign’s use of the power of protocols to reach voters, harvest their data, incentivize and, ultimately, shape their participation in the campaign. In demonstrating the kind of rhetorical spaces networked software establishes and the access it permits, prevents, and molds, Brown makes a major contribution to the emergent discourse of software studies as a major component of efforts in broad fields including media studies, rhetorical studies, and cultural studies.

Abstract

Before new interventions can be used in disease control programmes, it is essential that they are carefully evaluated in “field trials”, which may be complex and expensive undertakings. Descriptions of the detailed procedures and methods used in trials that have been conducted in the past have generally not been published. As a consequence, those planning such trials have few guidelines available and little access to previously accumulated knowledge. In this book the practical issues of trial design and conduct are discussed fully and in sufficient detail for the text to be used as a “toolbox” by field investigators. The toolbox has now been extensively tested through use of the first two editions and this third edition is a comprehensive revision, incorporating the many developments that have taken place with respect to trials since 1996 and involving more than 30 contributors. Most of the chapters have been extensively revised and 7 new chapters have been added.

Abstract

How does the motor cortex enable mammals to generate accurate, complex, and purposeful movements? A cubic millimeter of motor cortex contains roughly ~10^5 cells, an amazing ~4 Km of axons and ~0.4 Km of dendrites, somehow wired together with ~10^9 synapses. Corticospinal neurons (a.k.a. Betz cells, upper motor neurons) are a key cell type, monosynaptically conveying the output of the cortical circuit to the spinal cord circuits and lower motor neurons. But corticospinal neurons are greatly outnumbered by all the other kinds of neurons in motor cortex, which presumably also contribute crucially to the computational operations carried out for planning, executing, and guiding actions. Determining the wiring patterns, the dynamics of signaling, and how these relate to movement at the level of specific excitatory and inhibitory cell types is critically important for a mechanistic understanding of the input-output organization of motor cortex. While there is a predictive microcircuit hypothesis that relates motor learning to the operation of the cerebellar cortex, we lack such a microcircuit understanding in motor cortex and we consider microcircuits as a central research topic in the field. This Research Topic covers any issues relating to the microcircuit-level analysis of motor cortex. Contributions are welcomed from neuroscientists at all levels of investigation, from in vivo physiology and imaging in humans and monkeys, to rodent models, in vitro anatomy, electrophysiology, electroanatomy, cellular imaging, molecular biology, disease models, computational modeling, and more.

Abstract

Humans are not unique in using tools. But human tool use differs from that known to occur in nonhumans in being very frequent, spontaneous, and diversified. So a fundamental issue is, what are the cognitive and neural bases of human tool use?This Research Topic of Frontiers provides a venue for leading researchers in the field of tool use to present original research papers, integrative reviews or theoretical articles that further our understanding of this topic.Articles address a wide range of issues including, for instance, the nature of the underlying representations (e.g., conceptual, sensorimotor), the mechanisms supporting the incorporation of tools into body schema, the link between imitation and tool use, or the evolutionary origins of human tool use.Articles are included from experimental psychology, neuropsychology, neuroimaging, neurophysiology, developmental psychology, ethology, comparative psychology, and ergonomics. The goal of this Research Topic of Frontiers is to provide a state-of-the-art view of the field.

Abstract

Developing the third dimension. The origins and evolution of civilian aviation infrastructure in Switzer-land, 1909-1990&#xD;&#xD;Why is Switzerland’s biggest airport today located at Zurich-Kloten? What role has airplane noise played in development of the Geneva-Cointrin and Basel-Mühlhausen airports? How were the first airways established in Switzerland and how long have air traf-fic controllers been used there? &#xD;&#xD;This is the first comprehensive portrayal of the history of airports, airfields and air traffic control in Switzerland, from their begin-nings and up through the end of the 20th century.&#xD;Rather than focus on specific facilities separately, the author takes a Switzerland-wide perspective which he situates in a global con-text. Using extensive source material, he reconstructs the origins and development of Swiss aviation infrastructure and illuminates the impacts of regulatory frameworks and historical actors upon this development. He takes into account a broad spectrum of fac-tors, such as crucial international influences, the competition be-tween airports that has persisted since the interwar years, the role of the Swiss federal government, and issues concerning aircraft noise that emerged after the Second World War. In addition to to-day’s airports, this study also examines long-since discontinued facilities and important projects which were proposed but never completed, including the European central airport for interconti-nental seaplanes at Lake Constance, and the Swiss central airport at Bern-Utzenstorf and Lake Neuchâtel.

Abstract

The deterioration of skeletal muscle performance (e.g., declines in muscle strength and motor performance) with advancing age has long been anecdotally recognized as Shakespeare pointed out nearly a half millennium ago in his monologue The Seven Ages of Man, and has been of scientific interest for well over a century. Over the past several decades the scientific and medical communities have recognized that reduced skeletal muscle performance is a debilitating and life threatening condition in the elderly. For example, the age-associated loss of muscle strength, as well as impairment in the ability to finely control movement, is highly associated with physical disability and difficulty performing activities of daily living. While the nervous system is widely recognized for its role in controlling skeletal muscle during motor function, its role in determining the performance characteristics of aged skeletal muscle has largely been understudied. Historically, it was believed that these reductions in muscle performance were primarily resultant of age-associated adaptations in skeletal muscle (e.g., muscle atrophy). However, aging is associated with widespread qualitative and quantitative changes in both the central and peripheral nervous systems that are likely to influence numerous aspects of muscle performance, such as muscle strength, fatigue, and motor control, as well as mobility. In this research topic, we sought to examine a broad range of issues surrounding: 1) the age-related changes in nervous system anatomical, physiological, and biochemical changes in the central and/or peripheral nervous systems; 2) the functional role of these nervous system changes in contributing to altered skeletal muscle performance and/or mobility; and 3) physical and pharmacologic interventions that act via the nervous system to enhance muscle performance and/or mobility. Researchers and academicians engaged in aging, neuroscience, and/or applied physiology research focused within the scope of this research topic, were encouraged to contribute an original research article, review article, clinical case study, hypothesis and theory article, method article, opinion article, or technology report to this research topic. Herein, we present a series of outstanding articles within this scope of work, including a last minute addition article from Wiesmeier, Dalin and Maurer that is not mentioned in the editorial, that we hope will help to vertically advance the intersecting fields of aging/geriatrics and neuroscience. Lastly, as the editors, we wish to thank all article contributors and peer reviewers for their efforts in contributing to this Research Topic journal issue/book. Additionally, we would like to thank people everywhere who volunteer their time and body for human subjects research studies, such that are presented herein. It is the wonderful individuals who are willing to participate in experiments that make scientific exploration and health and medical advancements possible.
