Abstract:
A wind turbine performs the function of converting the energy (kinetic) derived from the wind into another form of energy (mechanical) which is employed for the purpose of driving the generator which in turn generates electricity from this mechanical energy. The most common types of windmills employed in practice include horizontal and vertical axis wind mill. These windmills are fabricated in different structures for producing electricity. The main objective of this paper is to design an innovative eco friendly windmill to overcome the various difficulties existing in conventional windmills. In conventional windmills, the propeller rotation depends on the velocity of wind flow in the environment. But in this paper, we have fabricated an innovative eco friendly windmill in which, the propeller rotation is increased four times for the wind velocity in the surroundings.

Abstract:
Breeding bird populations were monitored at a windmill park on Båtskär in southern Åland archipelago 2006–2011. The area is in the outer archipelago and consists of four islands holding six windmills. The operation of windmills started during fall 2007. An environmental impact assessment for the area was done in 2002. The area holds 850–1050 pairs of breeding birds annually. Two species had significantly decreasing trends, namely herring gull Larus argentatus (annual decrease 6.9 pairs, p=0.003) and lesser black-backed gull Larus fuscus fuscus (annual decrease 2.8 pairs, p=0.004). The reason for the decline of the herring gull population is unlikely to be related to the windmill park. However, the close proximity of a windmill to the breeding colony of lesser black-backed gull has most likely contributed to their decline. Some species like swallow Hirundo rustica, house martin Delichon urbicum and auks Alcidae have benefitted of the construction of the windmill park and utilize new small environments created by the construction.

Cook, Paul B. and John S. McReynolds. Modulation of sustained and transient lateral inhibitory mechanisms in the mudpuppy retina during light adaptation. J. Neurophysiol. 79: 197–204, 1998. Two functionally and anatomically distinct types of lateral inhibition contribute to the receptive field organization of ganglion cells in the vertebrate retina: sustained lateral inhibition (SLI), which is present during steady illumination and transient lateral inhibition (TLI), evoked by changes in illumination. We studied adaptive changes in these two lateral inhibitory mechanisms in the mudpuppy retina by measuring the responses of on-off ganglion cells to spots of light in the receptive field center, in the absence and presence of a concentric broken annulus (windmill) pattern, which was either stationary or rotating. SLI was measured as the percent suppression of the centered spot response by the stationary windmill and TLI was measured as the additional suppression produced when the windmill was rotating. In dark-adapted retinas SLI was elicited by windmills of 600 or 1,200 μm ID, but TLI could not be elicited by windmills of any size, over a wide range of windmill intensities and rotation rates. Exposure of dark-adapted retinas to diffuse adapting light caused an immediate decrease in the response to the spot alone, followed by slowly developing changes in both SLI and TLI: SLI produced by 1,200 μm ID windmills became weaker, whereas SLI produced by 600 μm ID windmills became stronger. After several minutes strong TLI could be elicited by both 600 and 1,200 μm ID windmills. The changes in SLI and TLI were usually complete within 5 and 15 min, respectively, and recovered to dark-adapted levels slightly more slowly after the adapting light was turned off. However the changes in sensitivity of the spot response were complete within one minute after onset and termination of the adapting light. The adaptive changes in SLI and TLI did not depend on the presence of the adapting light; after a brief (1 min) exposure to the adapting light, the changes in SLI and TLI slowly developed and then decayed back to the dark-adapted level. The effects of the adapting light on SLI were mimicked by dopamine and blocked by D1 dopamine receptor antagonists. However dopamine did not enable TLI in dark-adapted retinas and dopamine antagonists did not prevent enablement of TLI when dark-adapted retinas were exposed to light or disable TLI when applied to light-adapted retinas. The results suggest that light-adaptive changes in SLI are mediated by dopamine and are consistent with a reduction in electrical coupling between neurons that conduct the SLI signal laterally in the retina. In contrast, TLI appears to be switched off or suppressed in the dark-adapted retina and enabled in light-adapted retinas, by a relatively slow modulatory mechanism that does not involve dopamine.

Abstract:
Water-pumping windmills are reliable alternatives to provide water in some areas isolated from the electricity network, especially those with poor wind sources that are insufficient to operate wind turbines to generate electricity. The successful design of windmills for water pumping requires careful study of many variable parameters depending on the wind pattern and topography of the site. However, in this study, the researchers relied on the application of an integrated approach between forwarding Engineering (FE) and Reverse Engineering (RE), with the aim of obtaining a 3D CAD model of a water pumping windmill system.This 3D model will be the basis for manufacturing the windmill prototype that will be installed at a pilot site in a suburb of the city of Tajoura within a research project. The FE activities cannot be neglected when applying RE for the successful manufacturing of the windmills. The wind data recorded at the Center for Solar Energy Research and Studies (CSERS) for several years was used for calculating daily and monthly average wind speed and studying the daily wind pattern. The analysis of the collected wind data showed that the minimum and maximum daily average wind speed at Tajoura varies from 2.35m/s to 4.69 m/s, and theannual average wind speed is 3.24m/s. Among the Forward design, activity is estimating the wind resources available at the site for sizing the system to provide the site water requirements of 5 m³/day. From this point on, a commercial water-pumping windmill of 4.88m (16ft and a standard tower height of 12m were chosen to be the target of a RE application to obtain a CAD model. RE is accomplished in three phases: digitizing the component (part), processing the measured data, and creating the CAD model. To adopt the 3D model for all parts, they must be compared with the original scanned data using Deviation Analysis in CATIA. Afteradopting the 3D models of all the system components, the 3D assembly models were created based on the integrated approach between RE and FE. Finally, it is worth noting that the windmills for water pumping could not be manufactured solely by just applying reverse engineering.

Abstract:
Abstract The issues produced withinside the traditional windmills instigate the development of vortex bladeless windmills. Vortex Bladeless is a vortex caused vibrations resonant wind generator. It harnesses wind strength from a phenomenon of vorticity referred to as Vortex Shedding. Basically, Bladeless era consists of a cylinder regular vertically with an elastic rod. The cylinder oscillates on a wind range, which then generates electricity through a trade system. In exclusive words, its wind generators which is not genuinely a turbine. In other words, wind turbines are not real turbines. In this current paper we have tried to upgrade the Vortex windmill which is more comparable to solar panels in terms of functionality and cost-effectiveness compared to everyday wind turbines and entire project uses less planetary area. Through the improvised model we look forward to produce 238.60Wh of power. The work is designed in such a manner that it can be portable i.e., can be carried from one place to another.

Abstract:
Windmills constitute a valuable part of cultural heritage, especially in Greece, as unique structures of popular architecture and know-how of the pre-industrial era. Their wooden mechanisms were of exceptional constructional ingenuity, with the Mediterranean ones bearing a vertical wing and a rotating roof (“trula”), with a manual torsion mechanism that allowed for operation in all wind directions. Sikinos is a small Aegean island characterized by rich landscapes, which do not have wood-producing forests, but only sparse Juniperus phoenicea shrub land mixed with evergreen hardwood species and the presence of numerous sclerophyllus vegetation species (maquis). Three abandoned windmills are still preserved on the island today, but only two of them appear to have their wooden mechanisms left. In the one windmill mechanism examined, it was found that different wood species were used to manufacture its individual parts. Oak wood was used in most of the large elements, with the exception of the sprattle beam (“zigos”), which is made of fir wood. The local juniper was not used in any crucial part of the mechanism, though it was used only as a structural material on the first floor (“anogio”) flooring, along with large-diameter olive trunks. The findings of this study highlighted the thorough knowledge of the properties of various wood species and the effective use of simple tools toward the construction of functional and effective windmill mechanisms.

Abstract:
Renewable energy is likely to be of great importance in decades to come due to increased energy consumption. Kinetic energy from wind is expected to cover a part of this need, and wind farms are so far built onshore or at shallow water. On the other hand wind turbines are not always wanted close to land due to both the visual aspects and bird life. An alternative may therefore be to place wind turbines offshore. However, large water depths are causing problems for existing bottom fixed structures and floating wind turbines may therefore be a solution. In this thesis feasibility of tension leg anchor systems for floating wind turbines is investigated. A literature study including tension leg principles, relevant load parameters and methods for calculating motions on tension leg structures are looked into. Preliminary calculations of motion based on a one degree of freedom model are coded and executed in Matlab. Finally, a model in scale 1:100 has been built and further exposed to regular waves in a laboratory test. Numerical and experimental results are investigated and compared for different wave parameters in order to reveal potential weaknesses of the concept. Numerical and experimental results coincide quite well for structure motion in the wave direction, and in most cases the structure get small motion amplitudes which generate negligible vertical motions in form of set down. The overturning moment calculations also coincide well, and show that there are limitations in the mooring feasibility when exposed to large waves. The pretension is proven to be a very important parameter for the concept. Measurement of tendon forces from laboratory test show that the model is loaded differently and in larger order of magnitude than expected. For the scaled model a simplified tendon attachment arrangement in form of a steel plate is used. The strange force distribution may therefore represent loading on this plate. The results however show that tension leg anchoring can be a relevant alternative type of anchor system for floating wind turbines if sufficient system pretension is obtained. In addition, if also a reasonable magnitude and distribution of mass are obtained, the structure is expected to handle quite large waves. The design presented in this thesis is far from optimized. For further work it is therefore advised to model the structure in software where structural analysis can be executed in order to decide upon an optimized structural weight, seeing this as an important parameter.

Abstract:
Important stages in the development of a wind energy operated irrigation system, which is simple in design and easy to maintain, are described from model tests in wind tunnels through to a prototype prepared for field tests. The attention is focussed on gross features of the protoype including the blade geometry and aspect ratio; mast, sleeve and bearing assemblies; braking system and a load matching concept. Described towards the end are the field test arrangements of the prototype and associated instrumentation. Even according to the most conservative estimate, the prototype tests suggest that the windmill should be able to deliver around 3000 liters of water per day (eight hours of wind) to a head of 5 m in a 24 km/h wind.

Abstract:
The objective of the thesis is to establish methodology for development of a wind turbine, simple in design and easy to maintain, for possible application in developing countries. To that end the Savonius configuration is analyzed in detail both experimentally and analytically to lay a sound foundation for its performance evaluation. Following a brief review of relevant significant contributions in the field (Chapter I), an extensive wind tunnel test-program using scale models is described which assesses the relative influence of system parameters such as blade geometry, gap-size, overlap, aspect ratio, Reynolds number, blockage, etc., on the rotor output. The parametric study leads to an optimum configuration with an increase in efficiency by around 100% compared to the reported efficiency of ≈ 12 — 15%. Of particular interest is the blockage correction procedure which is vital for application of the wind tunnel results to a prototype design, and facilitates comparison of data obtained by investigators using different models and test facilities. With the design and performance results in hand, Chapters III — VI focus attention on analytical approaches to complement the test procedure. Using the concept of a central vortex, substantiated by a flow visualization study, Chapter III develops a semi-empirical approach to predict the rotor performance using measured stationary blade pressure data. The objective here is to provide a simple yet reliable design tool which can replace dynamical testing with a significant saving in time, effort, and cost. The simple approach promises to be quite effective in predicting the rotor performance, even in the presence of blockage, and should prove useful at least in the preliminary design stages. Chapter IV describes in detail a relatively more sophisticated and rigorous Boundary Element Approach using the Discrete Vortex Model. The method attempts to represent the complex unsteady flow field with separating shear layers in a realistic fashion consistent with the available computational tools. Important steps in the numerical analysis of this challenging problem are discussed at some length in Chapter V and a performance evaluation algorithm established. Of considerable importance is the effect of computational parameters such as number of elements representing the rotor blade, time-step size, location of the nascent vortices, etc., on the accuracy of results and the associated cost. Results obtained using the Discrete Vortex Model are presented and discussed in Chapter VI, for both stationary as well as rotating Savonius configurations. A detailed parametric study provides fundamental information concerning the starting and dynamic torque time histories, power coefficient, evolution of the wake, Strouhal number, etc. A comparison with the flow visualization and wind tunnel test data (Chapter II) shows remarkable correlation suggesting considerable promise for the approach. The thesis ends with concluding remarks and a few suggestions concerning possible future research in the area.

Abstract:
Increasing demand for clean and effective energy production turns interests of the world on floating offshore wind technology. To establish floating wind farms, a wind turbine have to be mound on a floating structure. The floating structure has to be carefully design according to sea environmental condition and kept in precise position. Different types of floating structure and stationkeeping systems have been proposed for floating wind turbines. This project deals with design a spar floater with tension leg mooring system, where the vertical fairlead position located between center of buoyancy and center of gravity. In this project a details study about floater design and tension leg concept was presented. Further, a model was established in computer program RIFLEX and static and dynamic analysis was carried out for two different environmental conditions, one for an operation condition to understand the model behaviour in normal sea state. The second one was for extreme condition to estimate the extreme tether forces and find out slacking possibility.

Abstract:
Cross flow wind turbines are not unique. The performance of Savonius and Darrieus turbines is well documented. Both share the advantage of being able to accept fluid flow from any direction. The Savonius is drag based and hence has poor power output while the Darrieus is lift based. Due to the fact that the Darrieus has fixed blades the fluid flow through the rotor does not result in optimal lift being generated at all points in the rotation circle. A drawback of the Darrieus system is that it has to operate at a high tip-to wind-speed ratio to obtain reasonable performance with the fixed blades. Deviation from a small optimal range of tip speed ratios results in poor performance. The Darrieus also has poor starting torque. The research conducted in this project focused on overcoming the shortcomings of other turbines and developing an effective cross flow turbine capable of good performance. A number of different concepts were experimented with, however all were based on a symmetrical aerofoil presented to the actual relative airflow at an angle that would produce the highest lift force at all times. The lift force was then utilized to generate movement and to do work on an electrical generator. All concepts contemplated were researched to ascertain their appropriateness for the intended application. During development of the final experimental platform and after lodging of a provisional patent (RSA 2007/00927) it was ascertained that the design shared some similarities with an American patent 5503525 dated 28/4/1994. This patent employed complex electronic sensing and control equipment for control of blade angle. This was thought to be overly complex and costly, particularly for small scale wind energy generation applications and a simpler mechanical solution was sought in the design of the final experimental platform used in this project. The design of the mechanical control system was refined in an attempt to make it simpler, more durable and employ the least number of moving parts. Literature studies and patent searches conducted, suggested that the mechanical control system as developed for the final experimental platform was unique. The enormous variation in the power available from the wind at the different wind speeds likely to be encountered by the device necessitated some means of control. In high wind conditions control of the amount of wind power into the device was deemed to be the preferable means of control. A number of different concepts to achieve this were devised and tested. The final concept employed limited the tail angle deflection and hence the lift produced by the aerofoils. This resulted in a seamless “throttle” control allowing the device to be used in any wind strength by adjusting the control to a position that resulted in the device receiving a suitable amount of power from the wind. The outcome of performance tests conducted indicated that the device has the potential to be developed into a viable wind turbine for both small and large scale applications. The ability to control the power input from the wind to the machine from zero to a maximum is considered to be one of the most beneficial outcomes of this project and together with the quiet operation and low speed, are considered the main advantages of the device over existing wind turbine designs. The possibilities of using the device to compress air for energy storage are exciting avenues that warrant further research.

Abstract:
United States strategic export controls—which treat commercial satellite technologies, related technical data, and defense services as munitions subject to the strictest export control criteria—have been under fire for decades. Critics argue that in attempting to bolster national security by limiting the transfer of space technologies to adversaries and potential adversaries, the U.S. has unintentionally and paradoxically harmed national security by undermining the space industrial base, the academic and research institutions that feed and grow that base, and the international partnerships that drive sci entific and technological advancement. There are few, if any, unequivocal supporters of the U.S. export control regime as it stands. As a result, both regulatory and statutory reform initiatives are afoot. Yet this begs the question: if the problems are and have been so apparent, why have the regulations and concomitant organic legislation not been subject to reform before now? This thesis will deconstruct the current discourse (keeping in mind its historical underpinnings) and challenge the orthodoxies of the export control reform debate in order to determine, to the extent possible, the merits of individual arguments and claims.
La stratégie des Etats-Unis quant au contrôle des exportations, qui inclut les technologies des satellites commerciaux, leur données techniques, ainsi que les services de défense en tant qu'armes sujettes à des critères plus stricts de contrôle des exportations, essuie les critiques depuis des années. Ses détracteurs avancent qu'en essayant de renforcer la sécurité nationale par des restrictions au transfert de technologies spatiales à ses ennemis et adversaires potentiels, les Etats-Unis ont, malgré eux et paradoxalement, nui à la sécurité nationale en négligeant les bases de l'industrie spatiale, les centres de recherche et universitaires qui nourrissent et développent celles-ci, ainsi que les partenariats internationaux qui conduisent au progrès scientifique et technologique. Il y a peu, si ce n'est, aucun partisan inconditionnel au régime de contrôle des exportations américain tel qu'il est à l'heure actuelle. Par conséquent, des initiatives de réformes des lois et règlements se préparent. Cela soulève, cependant, la question suivante: si des problèmes sont si évidents, pourquoi les règlements et lois correspondantes n'ont-ils pas été sujets à une réforme plus tôt? La présente thèse a pour but de déconstruire le discours usuel (tout en tenant compte de ses fondements historiques) et remet en question la doctrine traditionnelle sur la réforme, dans le but de déterminer, autant que faire ce peut, le bien-fondé des raisons et revendications individuelles, en démêlant, notamment, le vrai du faux.

Abstract:
The use of GIS tools in the preparation of the Master Plan for the Region of Murcia’s Windmills has facilitated the documentation work, study and analysis of the complex context in which these heritage elements are inserted, considered B.I.C. (Bien de Interés Cultural - Asset of Cultural Interest) with monument category and therefore subject to unique protection and tutelage. The GIS analysis allows the integration of information from different sources that respond, among others, to variables such as the territorial variables that link the windmills to a system of corridors of cattle trails and wadis; those of a productive nature associated with their own functionality in milling processes or water extraction in agricultural and salt exploitation processes, etc.; those related to landscape values and their impact on the construction and characterisation of the different landscapes. In this way, a model is generated which, by combining or discriminating the different variables, makes it possible to specify relationships between individual elements, identify settlement patterns or recognise singularities. The joint vision of all these aspects enables a reading beyond the current situation of the windmills as isolated pieces subject to recovery as unique elements of the landscape, but also enables a different way of thinking about the windmill complex, as a whole, as a system. Nodes in an ecosystemic network or, in other words, elements that can become part of a large green network as cultural services associated with nature.

Abstract:
The windmill is one of the important applications of wind energy and it is one of the best and the easiest ways to manipulate this wind power and use it for water pumping. The best feature of windmills is their high solidity, which gives high torque at the starting. Therefore, they will be able to lunch at low wind speeds like 2 m/s which gives a great possibility of utilizing, especially in the agricultural countries. This feature has been the focus of attention of researchers and developers over the long years. There are several factors affected by it, the most prominent of which is the number of blades and the diameter of the rotor. Some researchers have tested with different models of different diameters and others did on different numbers of blades. The challenge is how to find a model with an ideal number of blades and diameter that can give us the highest torque value under low wind conditions. In this paper, the multi-bladed horizontal axis wind turbines, which are used for water pumping, are discussed. Besides, the literature review is described, which presented the basic design requirements for windmill rotors as solidity, diameter, and tip speed ratio, also information given about materials that used in manufacture. The investigations of this paper are focused on the effect of the number of blades to reach the main goal and the best performance at located wind speeds.

Full text
Abstract:
Bernanke and Blanchard (2023) use a simple dynamic New Keynesian model of wage-price determination to explain the sharp acceleration in U.S. inflation during 2021-2023. They claim their model closely tracks the pandemic-era inflation and they confidently conclude that “… we don’t think that the recent experience justifies throwing out existing models of wage-price dynamics.” This paper argues that this confidence is misplaced. The Bernanke and Blanchard is another failed attempt to salvage establishment macroeconomics after the massive onslaught of adverse inflationary circumstances with which it could evidently not contend. It misrepresents American economic reality, hides distributional issues from view, de-politicizes (monetary and fiscal) policy-making, and sets monetary policymakers up to deliver significantly more monetary tightening than can be justified on the basis of more realistic model analyses
