Sea Clam Wave Energy Converter

After five years of research, the U.K. wave energy programme is nearing a point of decision on whether to progress towards full-scale testing or to continue on a research basis with reduced funding . The decision will be almost certainly based on the potential economics of wave energy and as a result, several device research teams are firming up on their designs prior to a cost assessment by consultants towards the end of this year. The chosen device or devices will probably have to produce electricity for the national grid at an estimated cost of less than 5 pence per unit at today's prices based on the costings of a 2 GW station located off the Outer Hebrides. Sea Energy Associates Limited and the Coventry (Lanchester) Polytechnic have been involved in the national wave energy programme since 1975, first, on the 1/lOth scale duck programme, (1, 2) and then more recently, on the second generation device known as the Clam (3). The Clam arose out of the need to redl'ce the high costs attributed to the first generation of wave energy devices and represented a new approach to the problem by an experienced team. By defining a sjmple concept which utilised components already identified as attractive, whilst at the same time avoiding known problem areas, the Clam quickly evolved into its 1979 design (3). This design has been tesled at 1/SOth scale in both natural and indoor waves with very satisfying results. Optimisation of the 1979 design has led to further design improvements which reduce the capital cost and increase the overall productivity. The final 1981 design should meet the cost criteria laid down and still retain some potential for further development. This paper discusses the merits of the Clam device and reviews the progress to date. of a floating spine breathe in response to wave forces. This causes air to be forced through self-rectifying turbines into and out of the hollow spine, allowing interchange of air between Clam bags. The randomness of sea wave patterns allows phased operation of the Clam elements, enabling the spine to act as a stable reference body. Typically a 1 OMW generating unit would feature ten Clam elements on a 27 5 m long spine, moored at an angle to tne waves, as illustrated on the cover

Costing Annexe To Consultants Preliminary Report

The procedure for costing the Reference Designs of the Wave Power Devices is described in Chapter 3 of the Consultant's Preliminary Report. The detailed breakdown of the prices determined for each Device, together with tabulated comparisons of the data received from contractors, is given as an Appendix to this Cost Annexe. The following tabulated summaries cover the overall capital cost of the construction of a 200 MW installed capacity power station for each Device. They should not be taken outside the context of the Consultants Preliminary Report, in which the reservations to be placed both on the preliminary Reference Designs and on the preliminary costing exercise are clearly stated. During this study, time did not permit the exploration of the many avenues which are available for potential cost reduction both by redesign and the study of alternative construction procedures. In particular there has been no opportunity for discussion of the costing exercise with the Device Teams. However, a study of the cost breakdowns indicates areas in each Device where cost savings should be achieved by appropriate design changes or more detailed analysis

The Availability Model: Consultant's Working Paper Number 32

This note describes some results obtained from the Consultant's Availability Model. They are based on preliminary data provided by Y-ard on the reliability of devices, and by Kennedy & Donkin on the transmission scheme. It is estimated that about 20% of the total energy output of a system might be lost due to repairs of its component. (This does not include lossed due to routine maintenance activities) . Assuming a value of 5p/kwh, this is equivalent to a cost of about £40m per annum for a 2gw station. station. There are several possible ways of reducing such losses, however , the most important being: - The reduction of failure rates by improvements in design, added redundancy in critical areas, or additional preventive maintenance. The use of larger numbers of repair crews, boats, etc .. - The reduction of live repair times in order to take advantage of the short weather windows which occur during the winter months, and/or the improvement of access to devices so that repair work can be carried out in more severe sea conditions. The trade-offs which exist between investing money in these areas and the resultant savings in energy losses are discussed, with the conclusion that the optimal solution for any scheme is likely to be one that reduces such losses to a minimum, by capital investment or high O+M expenditure. The appendices give an outline of the Availability Model and a revision of the sea-state information given in Working Paper 24, based on a more extensive analysis of the data

TB52: Seasonal Population Trends and Productiveness of the Potato Aphid on Swamp Rose in Northeastern Maine

Studies were conducted in northeastern Maine to determine seasonal population trends and productiveness of the potato aphid on swamp rose. The results presented and discussed concern chiefly chronological and phenological aspects of the utilization of swamp rose as a primary host of the aphid; time-temperature developmental requirements of the aphid in spring; productiveness of the aphid in caged colonies on swamp rose in spring; population trends of the aphid on naturally occurring, undisturbed swamp rose in spring and in fall; populations of aphid eggs on swamp rose in November and again in mid-April of the following year; and a comprehensive assessment of the probable usefulness of results from surveys of abundance of the aphids or aphid eggs on swamp rose in making advanced estimates of abundance of the potato aphid on potatoes.https://digitalcommons.library.umaine.edu/aes_techbulletin/1147/thumbnail.jp

Peranan Polri Sebagai Penyidik Menurut KUHAP Dan Undang-Undang Nomor 2 Tahun 2002 Tentang Kepolisian

Setelah dilakukan penelitian kepustakaan dan penelitian lapangan maka diketahui : l. Polri mempunyai fungsi yang cukup kredibilitas dalam penegakan hukum di Indonesia, salah satu fungsinya adalah sebagai aparat penegak hukum yang berwenang melakukan penyidikan. 2. KUHAP tidak Memberikan kewenangan penuh kepada Polisi sebagai penyidik namun UU No. 2 Tahun 2002 tentang Kepolisian Negara Republik Indonesia sangat berbeda jauh jika dibandingkan dengan Undang-Undang No. 28 Tahun 1997 khususnya dalam hal sikap watak serta tata cara kerja yang cenderung lebih militeristik, serta memberikan dasar hukum yang cukup kuat untuk melaksanakan fungsinya sebagai aparat penegak hukum, termasuk penyidik. 3.Hambatan-hambatan yang ditemukan dalam menjalankan wewenang Polri sebagai penyidik adalah perilaku dari anggota Polri tersebut yang bertindak di luar batas kewajaran dan kewenangannya serta kebudayaan masyarakat yang menganggap berhubungan dengan polri berarti menambah permasalahan baru

TB39: Canada Plum, Prunus nigra Aiton, as a Primary Host of the Green Peach Aphid, Myzus persicae (Sulzer), in Northeastern Maine

Studies were conducted to determine the role of Canada plum as a host of the green peach aphid in northeastern Maine and to assess its importance as a source of infestation by the aphid on potatoes. The results relate chiefly to chronological and phenological aspects of the use of Canada plum as a primary host of this aphid; temperature developmental requirements of the aphid on this plant in spring; productiveness of spring migrants of the aphid in thickets and in cages; interrelationships between fall aphid populations on foliage, and egg deposition and overwintering to naturally occurring aphid colonies in spring and summer populations on potatoes.https://digitalcommons.library.umaine.edu/aes_techbulletin/1156/thumbnail.jp

Bodysnatching in Contemporary Anglophone Drama, 1996-2022

In this dissertation, I explore the ways in which contemporary theatre stages possibilities and crises of embodiment. In order to penetrate the complex relationships between character, performer, text, and production, I coin a critical term: theatrical bodysnatching. This term refers to a dissonance or power struggle made manifest in performance, in which a performer’s body seems to resist the character it inhabits in ways that enhance, rather than detract from, the thematics of a theatrical production. In order to demonstrate the power of theatrical bodysnatching, I analyze playtexts, theatrical performances, reviews, and performer interviews. I argue that theatre is a medium optimally suited for staging sociopolitical dialogue because it models a kind of self-reflexive critique, in which performing bodies both embrace and resist the demands of the playtext. As a result, theatre creates a provocatively charged experience for spectators and performers, in which both parties are thematically implicated in the aims and preoccupations of a given play. Just as the performer’s body does not dissolve but instead accomplishes the crucial work of ideological exposure, the audience also becomes a marked, integrated presence and source of commentary in these bodysnatching plays. In this dissertation, I harness a particular selection of Anglophone drama from the late 20th to early 21st century in order to demonstrate how the often uncanny, subversive nature of live performance allows for radical reconsiderations of embodiment. By examining the ways in which these strangely iterated characters— and the performers who portray them— unfold onstage, theatrical bodysnatching poses urgent questions of exploitation, agency, and resistance

Numerical Modeling of Transport Properties and Comparison to Laboratory Measurements

Transport properties, such as permeability and electrical conductivity, are important in many geophysical and petroleum applications. The microstructure of a porous medium and physical characteristics of the solid and the fluids that occupy the pore space determine the macroscopic transport properties of the medium. The computation of macroscopic properties from the rock microtomography is becoming an increasingly studied topic. The transport properties are especially difficult to determine at the microscopic scale. The purpose of this paper is to test the applicabilities to numerically calculate the geometrical and transport properties (electrical conductivity, permeability, specific surface area and surface conductivity) of porous, permeable rocks, given the digital CT microtomography images. To better address the relationship between geometrical properties and transport properties, we use a number of artificial low, medium- to high-porosity Finney’s (1970) sphere packs. Numerically calculated transport properties are compared with analytical and empirical equations on the Finney pack. In particular, numerically computed permeability on the Finney pack agrees well with the permeability calculated from the computed formation factor using an empirical relationship on the same structure. This illustrates the consistence of resolving different transport properties on the same structure and the possibility of multiphysics coupling in the future. We also apply all the numerical simulations on the 3D X-ray microtomography of 23.6% porosity Berea Sandstone with 2.8 micron resolution. Numerical calculations of electrical conductivity, permeability and specific surface area on mm[superscript 3] image will be compared to the laboratory measurements with those parameters on cm[superscript 3] core samples. The upscaling issue will be discussed when we compare the numerical results with laboratory measurements at a different scale. We also analyze the image resolution impact on different properties to better understand the discrepancy between numerical computations and laboratory measurements. This paper provides a complete work on the numerical simulations on different physics at different scales. Numerical calculations are compared with analytic, empirical rock physics equations and laboratory measurements.Schlumberger Limite
