Barchans are crescent-shaped sand dunes forming in aride regions with unidirectional wind and limited sand supply. We report analytical and numerical results for dune shapes under different environmental conditions as obtained from the so-called ‘minimal model’ of aeolian sand dunes. The profiles of longitudinal vertical slices (i.e. along the wind direction) are analyzed as a function of wind ...

In this research paper, a 10 minute period measured wind speed data at 10 m, 30 m, and 40 m heights are presented for one of the major provinces of Iran. Four stations in Khuzestan- Abadan, Hosseyneh, Mahshahr, and Shushtar- are analyzed to determine the potential of wind power generation in this province. From the primary evaluation and by determining mean wind speed and also the Weibull f...

Oyster aquaculture and seagrasses often co-occur are each vital to the ecological economic value of coastal ecosystems. Global declines in seagrasses, including Zostera marina , have recently been observed association with multiple factors, infection diseases such as seagrass wasting disease (SWD), caused by protist Labyrinthula zosterae . Protection has led restrictions on oyster due perceived...

The following paper deals with an automatic text classification method which does not require training documents. For this method the German Subject Heading Authority File (SWD), provided by the linked data service of the German National Library is used. Recently the SWD was enriched with notations of the Dewey Decimal Classification (DDC). In consequence it became possible to utilize the subje...

Absence epilepsy, characterized by spike-wave discharges (SWD) in the electroencephalogram, arises from aberrations within the circuitry of the cerebral cortex and thalamus that regulates awareness. The inbred mouse strain C3H/HeJ is prone to absence seizures, with a major susceptibility locus, spkw1, accounting for most of the phenotype. Here we find that spkw1 is associated with a hypomorphic...

Predicting the power obtained at output of photovoltaic (PV) system is fundamental for optimum use PV system. However, it varies different times day depending on intermittent and nonlinear environmental conditions including solar irradiation, temperature wind speed, Short-term prediction vital in systems to reconcile generation demand terms cost capacity reserve. In this study, a Gaussian kerne...

A method for generating electricity using high wind pressure generated by fast moving vehicles channelling the induced wind in the direction of the wind turbine; converting the energy of the wind into mechanical energy by using wind turbine; and converting the mechanical energy into electrical energy by using a generating device and can be used for applications.

the main objective of this study is evaluation and wind statistic analysis, investigation of wind regime role on discharge flow and direction of sediments transferring in the case study. thus, sabzevar station anemometer data duration 10 years statistic period (1996-2005) analyzed. sand drift potential amount of study area is 160.9 v.u and result drift directionâ is west as well as sand flux is...

This study compared dispersion calculations using a street network model (SIRANE) with results from wind tunnel experiments in order to examine model performance in simulating short-range pollutant dispersion in urban areas. The comparison was performed using a range of methodologies, from simple graphical comparisons (e.g. scatter plots) to more advanced statistical analyses. A preliminary ana...
