OBJECTIVE We aimed to evaluate the relationship between establishing an animal shelter in Erzurum and the number of suspected rabies bites between the years 2005 and 2012. MATERIALS AND METHODS A retrospective, repeated cross-sectional study was planned in Erzurum in the year 2013. Records between the years 2005 and 2012 were obtained from the Communicable Diseases Department of the Erzurum H...

Different wind power projects have different external economics level, the practical evaluation on which can provide reference for wind power projects selection and qualify the role of completed projects. In this paper, the external economies of wind power engineering projects were evaluated by employing VIKOR method. The basic theory of VIKOR method was firstly introduced, and then the empiric...

The estimation of flicker emission by a wind park is a complex issue because the network is shared with other loads or generators, even with other wind parks, which contribute to the flicker level. This estimation can be done by means of simulation as depicted in international standards, where the wind turbine generator (WTG) is simulated with a fictitious network, and the results of flicker em...

Spaced receiver (SR) radars have shown clear advantages over conventional Doppler beam swinging radars for the measurements of wind profiles at high temporal and spatial resolution. Several effective techniques for wind and turbulence measurements have been developed (Holloway et al. 1997, Cohn et al. 1997). These techniques provide a solution to the diffraction problem by either directly assum...

Interstellar neutrals penetrating into the inner heliosphere are ionized by photoionization, charge exchange with solar wind ions, and electron impact ionization. These processes comprise the first step in the evolution of interstellar pickup ion (PUI) distributions. Typically, PUI distributions have been described in terms of velocity distribution functions that cool adiabatically under solar ...

This paper presents the urban wind ventilation mapping from building frontal area index on the example of urbanised city, Hong Kong. The calculations of frontal area index for each uniform 100m grid cell are based on three dimensional building databases at eight different wind directions. The frontal area index were then correlated with land use classification map, and the results indicate that...

The major problem of wind turbines is the great variability of wind power production. The dynamic change of the wind speed returns the quantity of the power injected to networks. Therefore, wind–thermal generation scheduling problem plays a key role to implement clean power producers in a competitive environment. In deregulated power systems, the scheduling problem has various objectives than i...

[1] The effect on geomagnetic activity of solar wind speed, compared with that of the strength of the interplanetary magnetic field, differs with geomagnetic latitude. In this study we construct a new index based on monthly standard deviations in the H-component of the geomagnetic field for all geomagnetic latitudes. We demonstrate that for this index the response at auroral regions correlates ...

According to the characteristics of the correlation of multiple wind farm output, this paper put forwards a modeling method based on fuzzy c-means clustering and the copula function, and correlation wind farms are inserted into IEEE-RTS79 reliability system for risk assessment. By the probabilistic load flow calculated by Monte Carlo simulation method, the probability of the accident is derived...
