Holy Name High School Wind Turbine Feasibility Study

The objective of this IQP was to facilitate the eventual construction of a wind turbine at Holy Name High School. A feasibility study based upon the economic and social issues surrounding such a project will be presented, including documentation of the additional steps taken by the group regarding conferences, meetings and presentations to help secure a wind turbine for Holy Name. Our results conclude that it would be feasible for Holy Name to erect a 600 kW turbine on site

TARPON MONOPOD MARGINAL FIELD STRUCTURE SUBJECTED TO SEISMIC GROUND ACCELERATION

For seismically active areas it is preferred that the intensity and characteristics of seismic ground motion used for design be determined by a site specific study. Since Malaysia is not located within seismically sensitive zone, seismic ground acceleration tends to be neglected from dynamic load design of offshore structures within the region. However, it is reported that tremors have been occurring and felt by platform operators in Malaysian Water. As Tarpon Offshore Platform is relatively contemporary within PETRONAS assets in Malaysia, there are no available specific tarpon inspection requirements or maintenance guidelines. Platform robustness and integrity cannot be ascertained. In regards to recent study of PSHA which is carried out by site-specific study, it is obtained that the mean hazard predicted is somewhat higher than of seismic model published by other studies, as well as API benchmark for evaluation of seismic activity to an offshore structure for a particular region. In this paper, the platform response towards seismic ground acceleration is investigated. By taking extreme condition of environmental loads and suggested ground acceleration values, the author will define the threshold unit at which ground acceleration is possibly controls the overall performance of a marginal field platform. In conjunction with that, platform natural behaviour and ultimate resisting force is identified in order to evaluate the platform integrity hence verify the latter findings

The effect of sensor sheltering and averaging techniques on wind measurements at the Shuttle Landing Facility

This document presents results of a field study of the effect of sheltering of wind sensors by nearby foliage on the validity of wind measurements at the Space Shuttle Landing Facility (SLF). Standard measurements are made at one second intervals from 30-feet (9.1-m) towers located 500 feet (152 m) from the SLF centerline. The centerline winds are not exactly the same as those measured by the towers. A companion study, Merceret (1995), quantifies the differences as a function of statistics of the observed winds and distance between the measurements and points of interest. This work examines the effect of nearby foliage on the accuracy of the measurements made by any one sensor, and the effects of averaging on interpretation of the measurements. The field program used logarithmically spaced portable wind towers to measure wind speed and direction over a range of conditions as a function of distance from the obstructing foliage. Appropriate statistics were computed. The results suggest that accurate measurements require foliage be cut back to OFCM standards. Analysis of averaging techniques showed that there is no significant difference between vector and scalar averages. Longer averaging periods reduce measurement error but do not otherwise change the measurement in reasonably steady flow regimes. In rapidly changing conditions, shorter averaging periods may be required to capture trends

Offshore wind energy. Technical aspects and feasibility study of offshore on Spanish coasts

Wind energy is derived from the differential heating of the atmosphere by the sun, and irregularities on the earth’s surface. Although only a small fraction of solar energy reaching the earth turns into kinetic wind energy, the total amount is extremely huge. Therefore, this energy resource should be exploited. What we have tried to proof in this thesis is that if wind farms were built in Spain, it could prevent a large amount of CO2 from being emitted into the atmosphere and that is an economically viable solution for electricity production. To reach this conclusion this thesis has been divided into two blocks. The first one, more theoretical, studies in depth wind energy and offshore technology. It describes both the components of a wind turbine as the impacts and potential problems that offshore technology may have. The second block, analyses three possible wind farms in three areas of Spain with a high wind resource potential. To this purpose, it has been chosen different types of wind turbines with different powers in order to analyse the power generated by each wind farms, the distribution of costs and the economic viability.Outgoin

3D Recording and Interpretation for Maritime Archaeology

This open access peer-reviewed volume was inspired by the UNESCO UNITWIN Network for Underwater Archaeology International Workshop held at Flinders University, Adelaide, Australia in November 2016. Content is based on, but not limited to, the work presented at the workshop which was dedicated to 3D recording and interpretation for maritime archaeology. The volume consists of contributions from leading international experts as well as up-and-coming early career researchers from around the globe. The content of the book includes recording and analysis of maritime archaeology through emerging technologies, including both practical and theoretical contributions. Topics include photogrammetric recording, laser scanning, marine geophysical 3D survey techniques, virtual reality, 3D modelling and reconstruction, data integration and Geographic Information Systems. The principal incentive for this publication is the ongoing rapid shift in the methodologies of maritime archaeology within recent years and a marked increase in the use of 3D and digital approaches. This convergence of digital technologies such as underwater photography and photogrammetry, 3D sonar, 3D virtual reality, and 3D printing has highlighted a pressing need for these new methodologies to be considered together, both in terms of defining the state-of-the-art and for consideration of future directions. As a scholarly publication, the audience for the book includes students and researchers, as well as professionals working in various aspects of archaeology, heritage management, education, museums, and public policy. It will be of special interest to those working in the field of coastal cultural resource management and underwater archaeology but will also be of broader interest to anyone interested in archaeology and to those in other disciplines who are now engaging with 3D recording and visualization
