A 915-MHz boundary layer wind profiler with radio acoustic sounding system (RASS) was sited 8 km from a very tall (450 m) television transmitting tower in north-central Wisconsin during the spring, summer, and autumn of 1995. The profiler measured wind means and variances, and the RASS attachment measured virtual temperature. These quantities are compared to measurements from cup and sonic anem...

Flow past a single-line arrangement of evenly-spaced row trees, in an open territory, was numerically simulated under the action boundary-layer type oncoming flow, with strength “strong breeze”, based on Beaufort scale. By selecting Koelreuteria henryi as demonstrated tree species, spatial wind speed variations behind trees at pedestrian level, various heights and spaces, were analyzed to inves...

Wind-induced turbulence can strongly impact ecological processes in shallow lake ecosystems. The creation of shelter against wind be expected to affect both primary producers and herbivores aquatic food webs. Shelter may benefit particular more than others by changing relative resource availabilities for different producers. Herbivore community compositions affected either directly or indirectl...

Over the past two decades, computational fluid dynamics and particularly the finite volume method have been increasingly used to predict the performance of wind turbines within their environment. Increases in available computational power has led to the application of RANS-based models to more and more complex flow problems and permitted the use of LES-based models where previously not possible...

A fully automatic anemometer calibrator intended for performing fast and accurate calibrations has been developed to fulfil the increasing demand and strict requirements of the wind energy industry. Different sensors are connected to a computer where a virtual environment acquires and processes the incoming signals and controls a wind tunnel, allowing the calibration of the anemometer at the pr...

PURPOSE We examined the cross-sectional and longitudinal association between social network characteristics and street youths' shelter use, a determinant of health outcomes for homeless youth. METHODS We analyzed interview data from 138 street youth recruited through venue-based sampling in San Francisco, to assess the cross-sectional relationship between shelter use in youths' social network...

Environmental temperatures considerably affect the reptilian ability for thermoregulation and harsh climatic conditions may impose a highly effective body temperature regulation to lizards. Such demanding conditions are more common to extreme mainland habitats (e.g. deserts or mountains). To the contrary, islands have more benign climate conditions thanks to the thermal buffering effect of the ...

The Dynamics characteristic of Tower Crane is complicated under the wind excitation which complicates the wind-induced vibration response analysis. The random wind-induced response analysis of tower crane is presented based on finite element method and Virtual Excitation Method. The pulsating wind loads are changed into multiple-point correlation stationary excitation. This papers uses Davenpor...
