Wind data evaluation in the Maltese Islands

“…In addition, the MLE method supplies forecasts with favorable properties; that is, the forecasts are asymptotically centered, have normal asymptotic distribution, and are efficient [24]. According to some researchers, the Weibull function is the best for modeling the wind speed [25,26]. However, Hennessey, Aidan, and Ododo have expressed that the Weibull function does not model the wind speed well for regions having very low or calm wind speeds [27,28].…”

Abstract:The wind energy potential of the Antakya area was statistically analyzed based 8 years of wind data sets (2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009). The 4-parameter Burr, 3-parameter generalized gamma, and conventional Weibull distributions were regarded as suitable statistical models for describing wind speed profiles. The suitability of the models was tested by R 2 , RMSE, chi-squared, and Kolmogorov-Smirnov analysis. According to goodness-of-fit tests, the Burr distribution was found to be more suitable than the generalized gamma or Weibull distributions for representing the actual probability of wind speed data for Antakya. Based on the capacity factors estimated by the Burr model at a hub height, the power generation potential of a commercial 330-kW wind turbine was also determined. The results show that the available wind energy potential to generate electricity in Antakya is low; consequently, wind power would be suitable only for stand-alone electrical and mechanical applications, such as water pumps, battery charging units, and local consumption in off-grid areas.

“…It is listed as of Least Concern ‘LC’ on the global IUCN Red List (Crivelli, ) as well as on the IUCN Red List of Northern Africa (García et al., ). This species has a high genetic variability in its Mediterranean distributional area (Cimmaruta et al., ; Ferrito et al., ), and is classified as ‘vulnerable’ in the Red Data Book of the Maltese archipelago (Schembri and Sultana, ). Moreover, the species is threatened primarily by destruction of its habitats including eutrophication (Crivelli, ), secondarily by competition with introduced species, particularly mosquitofish, as well as capture for fishkeeping purposes in aquaria, and lastly for use as bait for fishing (Homski et al., ; García et al., ).…”

Summary The current study aims to update the range of Aphanius fasciatus occurring in inland aquatic systems, and to characterise the length–weight relationship of specimens caught in inland waters of the Northern Sahara of Algeria. Although the known distribution of A. fasciatus is restricted to coastal waters including islands of the Mediterranean region, visits to 39 hydrosystems in Northeast Algeria revealed the presence of the species at two sites: Oued Still and Lake Temacine. Both sites are in the Sahara Desert of Algeria, where the climate is hot and hyperarid. The surveyed populations perform their entire life cycle at the same sites. Analysis of a sample composed of 27 individuals captured in Oued Still allowed determination of the length–weight relationship. On average, females measured 4.2 ± 0.6 cm in length and weighed 1.1 ± 0.5 g; males were 3.2 ± 0.6 cm and 0.5 ± 0.2 g. Growth parameters of the von Bertalanffy equation for A. fasciatus were estimated at Lt = 5.5145 (1−exp (−0.341(t−0.0049))), Wt = 2.6692 (1−exp (−0.271t))3.
