Galactic feedback strongly affects the way galactic environments are enriched. We examine this connection by performing a suite of cosmological hydrodynamic simulations, exploring a range of parameters based on the galaxy formation model developed in Vogelsberger et al. (2013) (henceforth V13). We examine the effects of AGN feedback, wind mass loading, wind specific energy, and wind metal-loadi...

Land transformation (ha of surface disturbance/MW) associated with wind facilities shows wide variation in its reported values. In addition, no studies have attempted to explain the variation across facilities. We digitized land transformation at 39 wind facilities using high resolution aerial imagery. We then modeled the effects of turbine size, configuration, land cover, and topography on the...

Convective heat transfer at exterior building surfaces has an impact on the design and performance of building components such as double-skin facades, solar collectors, solar chimneys, ventilated photovoltaic arrays, etc. and also affects the thermal climate and cooling load in urban areas. In this study, an overview is given of existing correlations of the exterior convective heat transfer coe...

At temperate latitudes the synoptic patterns of bird migration are strongly structured by the presence of cyclones and anticyclones, both in the horizontal and altitudinal dimensions. In certain synoptic conditions, birds may efficiently cross regions with opposing surface wind by choosing a higher flight altitude with more favourable wind. We observed migratory passerines at mid-latitudes that...

Wind energy is a fast-growing and promising renewable energy source. The investment costs of wind turbines have decreased over the years, making wind energy economically competitive to conventionally produced electricity. Size scaling in the form of a power law, experience curves and progress rates are used to estimate the cost development of ever-larger turbines. In life cycle assessment, scal...

For the past few year renewable energy resources, without challenging environmental concerns has lead to significant increase in global power generation. Out of that wind energy is considered to be the most mature renewable energy source. However, the exploitation of wind energy is particularly challenging due to the stochastic nature of wind. This weak interconnection of wind generating source...

A significant challenge for unmanned aerial vehicles is flying long distances in the presence of wind. The presence of wind, which acts like a forcing function on the system dynamics, significantly affects control authority and flight times. While there is a large body of work on the individual topics of planning long missions and path planning in wind fields, these methods do not scale to solv...

Air moving into the open end of a passive sampler affects the pollutant mass transfer by generating eddies leading to a reduction in the molecular diffusion length and a consequent overestimation of the pollutant concentration. This decrease is found to be experimentaly in the range of 10-40 % depending on the wind speed at the site. Assuming that the eddy turbulence is isotropic and the horizo...

In this paper, the Renewable energy sources, which have been expected to be a promising alternative energy source, can bring new challenges when it is connected to the power grid. However, the generated power from wind energy source is always fluctuating due to environmental condition. In the same way wind power injection into the electrical grid affects the power quality due to the fluctuation...

Fluctuations in the solar wind characteristics such as speed, temperature, magnetic strength and density are associated with pulsations in the magnetosphere. Coherent magnetohydrodynamic waves in the solar wind may sometimes be a direct source of periodic pulsations in the frequency interval 1 to 7 mHz in the magnetosphere. In studies of the solar wind and the way its variation affects the magn...
