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.

Abstract:

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.

In this paper, we introduce graceful and near graceful labellings of several families of windmills. In particular, we use Skolem-type sequences to prove (near) graceful labellings exist for windmills with \(C_{3}\) and \(C_{4}\) vanes, and infinite families of \(3,5\)-windmills and \(3,6\)-windmills. Furthermore, we offer a new solution showing that the graph obtained from the union of \(t\) 5-cycles with one vertex in common (\(C_{5}^{t}\)) is graceful if and only if \(t \equiv 0, 3 \pmod{4}\) and near graceful when \(t \equiv 1, 2 \pmod{4}\).

Abstract:

bstract: Windmills have been a symbol of sustainable energy for centuries, and their relevance continues to grow in the modern era. This abstract explores the dual functionality of windmills for both pumping and power generation. Windmills have evolved from their traditional agricultural use to become versatile renewable energy sources, capable of harnessing wind energy for various applications. For pumping, windmills are employed to lift water from wells or reservoirs, providing a reliable source of water for irrigation and domestic use, especially in remote or off-grid areas. Their mechanical design, often featuring rotating blades, efficiently converts wind energy into rotational motion, driving a pump mechanism. In the realm of power generation, windmills are pivotal in the transition to cleaner energy sources. Modern wind turbines are designed with advanced aerodynamics and materials, enabling them to capture substantial kinetic energy from the wind. This energy is then transformed into electrical power through generators. Wind farms, comprised of multiple turbines, contribute significantly to electricity grids, reducing carbon emissions and dependence on fossil fuels. This abstract underscores the dual role of windmills as sustainable solutions for pumping and power generation, emphasizing their versatility and contribution to a greener future.

Abstract:

Abstract. Automatic detection of objects from Earth Observation images is still a challenge for researchers. This paper aims at extracting automatically windmills on mid-resolution images (10-meter resolution), based on Sentinel satellite products. Sentinel-2 optical images are obvious candidates for our study. At 10-meter resolution, a windmill is represented with only a few pixels. We also start to consider Synthetic Aperture Radar (SAR) Sentinel-1 images but no particular windmill radar response on GRD (Ground Range Multi-look Detected) products seemed to be relevant.Considering the maturity of deep learning techniques for object detection in computer vision, we explore the use of deep neural networks for windmill detection on remote sensing images. For that purpose, we had to create the training data sets but we took advantage of the availability of many Sentinel images and of the use of automated labelling as the objects are georeferenced. The proposed approach relies on the U-Net framework, reformulating our problem of object detection in terms of semantic segmentation. We trained several neural networks on different data sets emanating from different countries. That enabled us to measure the performance of detection within a country but also across two countries (training on a country and predicting on another country). The results show the ability of detection of such small objects with respect to the resolution and we obtain various levels of performances depending on the trained and test data sets.

Abstract:

Windmills are one of the most complex human inventions of the pre-industrial era. Making use of wind energy to serve human needs was not only a miracle of architecture and technology: it produced silent witnesses of history – an important part of a rural landscape, local identity and folklore. Thanks to their multiple roles, windmills are useful research objects for scientists in various fields. In Poland the first written records of windmills date from the ;(many of them still fully operational) despite losses in the war. Today there are around 250 windmills under legal protection (around 70 of which were moved to open-air museums). This figure illustrates the vulnerability and progressive disappearance of Poland’s windmills. Despite the efforts made to protect this heritage, often the only remnants of such objects are the memories people living nearby. These memories join the present with the past, recall people and their work, and preserve the memory of an item. Windmills that have ceased to exist are still present in people’s collective remembering as a sum of their subjective experiences and impressions. In this paper, we decided to combine different approaches to the matter of heritage – both tangible and intangible. We argue for the importance of collecting recollections of ordinary people and interviews with eyewitnesses, as well as examples of institutional or private efforts made to protect windmills, to explain the equal value of both of these methods for preserving memories about the work and skills of millers – that is, the memory of a profession that was once a vital part of cultural identity.

Abstract:

The world is heading towards maximum utilization of non-conventional energy resources like solar, Biofuel, Biogas and wind energy is also a part of it. The world has set a goal of 2030 up to which use of carbon emitting fuels is to be eliminated. The method of producing wind energy is Windmill. The windmills around us nowadays are of conventional type, means, they make use of Blades and rotor to convert wind energy into power. If we the structure of conventional windmill, we came to know that it is quite expensive and also carries additional cost of it’s maintenance, handling, transportation, and storage with it. Due to rotating parts and the metal property to get corroded with time makes it more expensive. We are trying to eradicate this drawbacks with our concept of Bladeless windmill. Our project will completely eliminate the blades and will give power without the extra cost carrying with it.

Abstract:

Purpose The purpose of this paper is to stimulate an urgent dialogue about the impact of automated opinion engines (“bots”) on the functioning of public institutions in democratic societies. While the use of political bots may or may not have influenced the recent US presidential election or the UK “Brexit” referendum, it is believed that the implications of the use of political bots are more broadly troubling. There is an urgent need for common standards to prevent the abuse of these powerful digital tools. Design/methodology/approach The paper is based on a review of recent pieces describing political bots and attempts to extrapolate our learnings from recent political campaigns to the broader context of the discussion of all public issues. Findings It was found that the use of political bots has a powerful ability to manipulate public opinion and could easily infect the totality of public discourse. Research limitations/implications The core data on which the author’s discussion is based are limited to primary research by a small number of data scientists. This pool needs to be significantly expanded. Practical implications The insights the author proposes should serve to stimulate an organized effort to develop common standards for the use of and to prevent the abuse of these automated opinion tools. Social implications Unless an effort along these lines is made, distrust in all democratic and transparent institutions is highly likely to decrease. Originality/value While much has been written about bots in politics, the author believes that this is the first attempt to trace the dangers of bots across a much broader set of community institutions.

Abstract:

The idea of bladeless windmills is based on the vortex shedding effect hypothesis. A wind-powered generator with the fewest moving elements is the vortex bladeless windmill. The oscillation or vibration caused by the wind is used to generate the electric current. As a result, piezoelectric material or a linear alternator are used to generate electricity. In this project effort, we attempted to increase the vortex-induced vibrations of the turbine built of Epoxy Carbon UD (230GPa) by altering the design of the mast and base. The maximum deflection is 0.22775m (condition 7) at 10 m/s2 acceleration.

Abstract:

Abstract The aim of this text is to evaluate the distribution of windmills in Pomerania, an area which stretches from Gdańsk to Toruń, over the period of the nineteenth century. The basic research method was to analyse various maps from both the early nineteenth century and the late nineteenth century. The results made it possible to state that the total number windmills increased by a factor of three, and that this referred mainly to cereal mills. The number of vertical windmills with rotating caps increased at the beginning of the nineteenth century, but the number of drainage windmills remained unchanged. The very high demand for wind energy was a result of significant economic development within the Prussian partition in the second half of the nineteenth century. Cartographic sources allowed this phenomenon to be verified in the most complete way.

Abstract:

Windmills are extremely interesting examples of architectural and technological monuments. For years, the objects located in Poland were neglected and their degradation was very rapid. There were many factors that contributed to this situation including unprofitable production, the ageing of staff, lack of successors, and insufficient financial resources of provincial conservators for the co-funding of conservation and restoration projects. Over the past few years, the number of initiatives, patterned on foreign practices, have been growing. Their aim is to preserve and popularise windmills. In many cases, windmills are converted into hotels or apartments.

Abstract:

Utilization of wind energy sources provides advantages in terms of being environmentally friendly, and it can be energy source is realible. The analysis of wind mill control using Neural Network model for Uncertain Variables or abbreviated as the VTP model is expected to provide a solution in solving the windmill control case. And the Neural Network model for Uncertain Variables uses probability techniques, degree of membership, logical OR function, linear programming and euclidean distance to reduce the learning process In this research, wind mill control uses variable air pressure and duration of sunshine to determine whether the wind mill is moving or not. Finally, this research tries to analyze windmill control, which in the future is expected to produce a smart wind mill control system. And the Neural Network model for Uncertain Variables can be used to control windmills with the different of input data

Abstract:

One of the most delicate parts to size in a water pumping windmill is the pump rod. Indeed, frequent ruptures during the exploitation and experimentation of windmills shows that the determination of the real forces acting on the pump rod is quite difficult to evaluate. The calculation of these forces is traditionally achieved by taking as a maximal force the sum of the static loads. The calculation model used in this article takes into account the hydraulic pressure losses, inertia forces and the shock force caused by the water column on the piston. This will make it possible to better know the forces acting on the pump rod and therefore to perform better sizing.

Abstract:

SummaryThomas Szasz's essay misses several key points about the undoubted changes that psychiatry has undergone since he wrote his original screed against the discipline in 1961. Szasz fails to recognise that the discipline today acknowledges a neurological basis for much psychiatric illness. Thus, his fulminations against psychiatry for treating ‘mental illness' is off-base. Szasz's original diatribe was heavily against psychoanalysis. Yet today Freud's doctrines can scarcely be said to play even a marginal role in psychiatry, and it is absurd to keep levelling the same old charges of 50 years ago. One has the feeling of looking at one of the last veterans of the Esperanto movement in confronting Szasz: lunacy at the time, bizarrely outdated today.
