Comparison in Sound Velocity Variability over Neap and Spring Cycle in Essay

Comparison in Sound Velocity Variability over Neap and Spring Cycle in Dart and Tamar Estuaries, UK and Its Impacts on Sonar Performances - Essay Example Studies of the variables of sound transmission aid those who need to know how well their equipment will function given different environments. This project entails the planning and execution of an oceanographic survey to determine the differences in sound velocity variables over the neap and spring tide cycles in the Dart and Tamar estuaries, and their impact on sonar-related performances. This study is largely based on research provided by Desiree Batton in conjunction with the Hydrographic Society, The Dart Observatory at the Britannia Royal Naval College and Graham Tattersall of the CEFAS Lowestoft Laboratory, as well as additional research. The tide cycles at the mouths of these two estuaries differ in some factors that influence the movement of sound. This paper plans to show what those factors are and how they affect sonar usage. The report will present data that was ascertained by using the current appropriate techniques and tools. It will analyze the variability of sound velocity, present the results and make determinations based on those analyses and calculations. Several determinations will be necessary to conclude this paper, such as the variations in bottom sound velocity as opposed to the variations in surface sound velocity. For instance the calculations for bottom sound velocity will take the higher level of mixing into account, while the calculations for surface sound velocity will need to look at temperature variables more, especially spring tide. Differing types of measuring equipment will be needed to gain the information required. In addition, time of day and the varying points of tidal activity are considerations that will add into the data. This project is designed to correlate with other projects that focus on sound speed or sound velocity. The need to understand how sound travels through tidal waters, in particular the Dart and Tamar estuaries, is of great significance to ongoing research. The research of A. D. Priestley

Problems of Defining and Measurement of Development Essay

Problems of Defining and Measurement of Development - Essay Example There are many geographers that measure the development in the terms of countries Human Development Index. On the other hand in various countries economists link the development with the developed or either with developing countries economies and use the GNP (Gross National Product) and GDP (Gross Domestic Product) for measuring it (Pieterse 2009). As the definition of development, it is important that technological justice and improvements are even interrelated features that require being considered. The study has been conducted for defining the problems that occur while defining the development taking place in the economy and the various measures adopted by the economists for measuring it on the specific index. The study will also include different theories that are applied in the development for defining it. The study will also include examples drawn from various countries for defining the development, as most of the countries use the income level for defining the development taking place in different countries (Jaffee 1998). The term development has been used from the past few decades and there are several definitions which are associated with the training, seminars, workshops, certificate programs, college and degree programs and also the books and other reading materials. The term development when initially discussed was treated as the synonym of the term improvement of individuals of a lot of individuals in society. With the passage of time, with the emergence of new initiatives and innovations, there is an addition to the confusion in the definition of the term development. There is confusion in the terminology that is used for defining the term â€Å"development†. From the international perspective, it can be said to be as an integral part of a large and broader process of the social and community change (Love and Guthrie 2011). The goal of this change is to bring in the efficiency and improvement in the activities related to economic and social justice.Â
