The effects of using three different cover materials (glass, Plexiglas, and plastic wrap) were investigated under a series of environmental conditions. The heat transfer model has been improved upon by the incorporation of a term for the effective emissivity of the cover, 蟿eff. The effective 蟿...
The oxidation process occurring in stockpiles of reactive materials, such as coal, induces a natural convection flow field within the pile. Due to porosity of the stockpile, this flow field is affected by the wind flow in the surrounding air. The wind sets up pressure variation around the pil...

Then animate your titles with one of over 100 drag-and-drop behaviors, and customize them with more than 90 3D materials like metal, wood, and stone. Transition any space from 2D to 3D, then set up shadows or reflective surfaces that move with the camera and lighting. Though not as ...
Wind Abrasion Wind abrasion is the process of the wearing away of a solid object due to the impact of particles carried by the wind. The wind picks up particles and moves them. When the particles collide with a solid object, the impact causes small pieces of the object to break off. ...
Waves and winds are continuously observed with an ultrasonic wave gauge and wind sensor at the end of the port. The height of the sea surface is recorded at 0.5 s intervals. Additionally, the time series in terms of the power spectrum is statistically analyzed. The heights of the significant...
With the rapid development of wind power, there are increasing concerns about the negative ecological effects of its construction and operation. However, previous studies have mainly focused on the effects of wind farms on flying fauna (i.e., birds and bats) or climate change separately from com...
weathering, disintegration or alteration of rock in its natural or original position at or near the Earth’s surface through physical, chemical, and biological processes induced or modified by wind, water, and climate. During the weathering process the translocation of disintegrated or altered materia...
