The principal purposes of this introductory paper are to identify and describe the main aspects of marine traffic engineering, and to suggest ways in which traffic engineering principles and methods developed for land and air transport systems may be applied to marine problems. Traffic engineering is a relatively new branch of engineering science, but it was quickly and widely recognized as essential in ensuring that all forms of land and air transport operate safely and efficiently. However, although sea transport is a long established activity, it is only during the past few years that marine traffic engineering has begun to emerge as a separate aspect of this broader scientific discipline.
During the eighteenth century Sweden was mostly at peace. The severe setbacks and losses experienced in the Great Nordic War (1700-1720) had once again reduced Sweden to a small nation on the northern fringes of Europe. New social forces started to influence its development and the economy, especially trade, began to expand. However, the military continued to be a major social force even during peacetime. Professor Gunnar Artéus has described the eighteenth century as a period of thorough militarization of society. The different branches of the armed forces employed more than ten per cent of the adult male population of Sweden (including Finland), and a major part of state expenditure went on military needs. The role of the armed forces in society during the eighteenth and nineteenth centuries has recently been the object of new research, underlining social and economic aspects rather than military. From this point of view the eighteenth-century Swedish Navy offers interesting possibilities for research. Naval personnel could sell their navigational skills on an international labour market, combining a career in the navy with work abroad or in the merchant marine. The aim of this article is to discover aggregated trends and tendencies in the careers of naval personnel during the eighteenth century by using naval merit lists delivered by them to the Admiralty.
ii. Sweden's naval merit lists
In 1732 the Swedish government laid down formal rules for merit lists for persons in naval service. The reason given for this action was the Admiralty's ambition to appoint the most capable and deserving persons to available positions. About two decades later, in 1754, it was decreed that all personnel should submit a merit list every three years. At the same time regulations were made for how to formally construct a list. It was to comprise ‘one column with dates for previous assignments, and a broader column with dates and short descriptions of the character of former assignments’. Merit lists or similar accounts were also needed in order to be entitled to pension funds. The Swedish Admiralty had already specified rules for the creation of a retirement fund for navy personnel (Amiralitets krigsmannakassan) in 1642 whereby part of the annual salary was to be paid into the fund by navy personnel.
Marine traffic engineering is defined as the study of marine traffic and the application of such studies to improvements in navigation facilities and traffic regulation. The authors review recent Japanese work in this field.
Since the mountainous terrain of Japan hindered the development of road transport, goods have mainly been sent by ship, from the earliest times until the end of the last century. The rapid economic recovery of Japan after the Second World War owes much to the industrial belt along the coast which may be called the ‘Water Megalopolis’, with more than 70 million inhabitants. Shipping provides the greater part of both interzonal and international transport and consequently there is severe traffic congestion, accentuated by the presence of more than 200,000 fishing vessels.
Gaining expertise in marine floating systems typically requires access to multiple resources to obtain the knowledge required, but this book fills the long-felt need for a single cohesive source that brings together the mathematical methods and dynamic analysis techniques required for a meaningful analysis, primarily, of large and small bodies in oceans. You will be introduced to fundamentals such as vector calculus, Fourier analysis, and ordinary and partial differential equations. Then you'll be taken through dimensional analysis of marine systems, viscous and inviscid flow around structures surface waves, and floating bodies in waves. Real-life applications are discussed and end of chapter problems help ensure full understanding. Students and practicing engineers will find this an invaluable resource for developing problem solving and design skills in a challenging ocean environment through the use of engineering mathematics.
Every building, and every computer program, has an architecture: structural and organisational principles that underpin its design and construction. The garden shed once built by one of the authors had an ad hoc architecture, extracted (somewhat painfully) from the imagination during a slow and non-deterministic process that, luckily, resulted in a structure which keeps the rain on the outside and the mower on the inside (at least for the time being). As well as being ad hoc (i.e. not informed by analysis of similar practice or relevant science or engineering) this architecture is implicit: no explicit design was made, and no records or documentation kept of the construction process.
Seventh wrangler in the Cambridge mathematical tripos in 1826, Henry Moseley (1801–72) was adept at applying mathematical analysis to a wide variety of problems. Appointed professor of natural and experimental philosophy and astronomy at London's newly established King's College in 1831, he was instrumental in creating the institution's department of engineering and applied science. This 1843 textbook is based on the lectures in statics, dynamics and structures that he gave to students of engineering and architecture. Moseley draws on the latest continental work in mechanics, and the treatment of problems is mathematically sophisticated. Starting with basic statics and dynamics, Moseley covers topics of interest to both civil and military engineers, with sections on the theory of machines and on the stability of walls, arches and other structures. Notably, the American edition of this work was adopted as a textbook by the United States Military Academy at West Point.
We discuss robustness in LE systems from the perspective of engineering, and the predictability of both outputs and construction process that this entails. We present an architectural system that contributes to engineering robustness and low-overhead systems development (GATE, a General Architecture for Text Engineering). To verify our ideas we present results from the development of a multi-purpose cross-genre Named Entity recognition system. This system aims be robust across diverse input types, and to reduce the need for costly and timeconsuming adaptation of systems to new applications, with its capability to process texts from widely differing domains and genres.
The command hierarchy of a ship-of-the-line in the eighteenth century has been widely written about within recent naval historiography. However, one area that has been largely overlooked is the conflict, in relation to their place in the ship's hierarchy, between the British Marine Corps officers and their Royal Navy counterparts and their eventual acceptance. The conflict reinforces the perception of the growing authority and centralization of command by the Admiralty. From the very start of the new marine divisions in 1755, the Admiralty constructed the new command structure in such a way as to integrate the marines, yet divide them from the navy. This new command structure would create friction between the marines and navy, especially among the officer ranks. One area of contention that existed between marine and naval officers was with regard to the marine officers' social backgrounds. These social conflicts existed as a result of the majority of marine officers coming from a substantially lower class than their naval counterparts. This created hostility within the ship's wardroom, even though the marine officers had the right to sit in the wardroom because of their commissions. To cure this problem, the marine officers developed three methods by which to integrate themselves into the command hierarchy via their amphibious operational roles. The first stage of this development was to use external influences, such as army commanders, to exert influence on their naval commanders to help marines in amphibious and command matters.
