    Elizabeth Tipton is an American statistician whose research focuses on causal inference from meta-analysis and robust variance estimation, especially for applications of social statistics in education and behavior. [1]

  3. Citicorp Center engineering crisis - Wikipedia

    en.wikipedia.org/wiki/Citicorp_Center...

    The concern was for the integrity of the building structure in high wind conditions. Estimates at the time suggested that if the mass damper was disabled by a power failure, the building could be toppled by a 70-mile-per-hour (110 km/h) quartering wind, with possibly many people killed as a result.

  4. Wind energy software - Wikipedia

    en.wikipedia.org/wiki/Wind_energy_software

    Wind farm monitoring software is a software that allows people to see if the wind turbines are running well or are going to become broken. Other functions of monitoring software is reporting, analysis of measurement data (power curve) and tools for monitoring of environmental constraints (bat control, etc.).

  5. Although a common classroom experiment is often explained this way, [449] Bernoulli's principle only applies within a flow field, and the air above and below the paper is in different flow fields. [450] The paper rises because the air follows the curve of the paper and a curved streamline will develop pressure differences perpendicular to the ...

    A typical study of a wind farm's Life cycle assessment, when not connected to the electric grid, usually results in similar findings as the following 2006 analysis of 3 installations in the US Midwest, where the carbon dioxide (CO 2) emissions of wind power ranged from 14 to 33 tonnes (15 to 36 short tons) per GWh (14–33 gCO 2 /kWh) of energy ...

    Anthony did not want to share his last name with the paper. There is evidence this virus is swapping genes. Wild birds carry a variant of H5N1 called D1.1 or D1.2.

  8. Wind resource assessment - Wikipedia

    en.wikipedia.org/wiki/Wind_resource_assessment

    Wind speeds can vary considerably across a wind farm site if the terrain is complex (hilly) or there are changes in roughness (the height of vegetation or buildings). Wind flow modeling software, based on either the traditional WAsP linear approach or the newer CFD approach, is used to calculate these variations in wind speed.

  9. Betz's law - Wikipedia

    en.wikipedia.org/wiki/Betz's_law

    In order to keep the wind moving through the turbine, there has to be some wind movement, however small, on the other side with some wind speed greater than zero. Betz's law shows that as air flows through a certain area, and as wind speed slows from losing energy to extraction from a turbine, the airflow must distribute to a wider area.
