Path Integral Solution of PT-/non-PT-Symmetric and non-Hermitian Hulthen Potential

The wave functions and the energy spectrum of PT-/non-PT-Symmetric and non-Hermitian Hulthen potential are of an exponential type and are obtained via the path integral. The path integral is constructed using parametric time and point transformation

Daily global solar radiation mapping of Turkey using Meteosat satellite data

Many studies have indicated that the estimation of solar irradiation at ground level using meteorological satellite data has been an alternative and easy method compared to classical methods. In the present work, the incident of solar radiation over Turkey has been estimated at ground level between July 1997 and December 1998. Statistical regressions between ground data and digital satellite data, measured in the visible band (0.4-1.1 µm) by Meteosat radiometer, have been determined and these regression parameters have been used to estimate solar radiation at ground level. This is the so-called statistical method, which uses a simple model because satellites measure only a few parameters among the many that govern radiative transfers. The visible image (C3D) data used in the present work was Meteosat Wefax type. While pursuing our studies the mean daily sum of global solar radiation over Turkey has been determined to be 18.44 MJ m-2 d-1 with a correlation coefficient of 0.96. The rms error for the mean daily sum has been evaluated as 1.92 MJ m-2 d-1. The monthly mean daily sum of solar radiation has been determined with an rms error of 1.82 MJ m-2 d-1 in two years. During this period the maximum value of the daily sum has been found to occur in June 1998 as 28.47 MJ m-2 d-1, whereas the minimum has been found to occur in December 1998 as 7.35 MJ m-2 d-1. The evaluation procedure, results and possible sources of error are suggested and possible ways of improving the method are described and discussed. © 2004 Taylor & Francis Ltd

Comparison of a new algorithm with the supervised classifications

In this study, a new classification algorithm in which only the selected pixels have been attempted to be classified (selected pixels classification: SPC) has been introduced and compared with the well known supervised classification methods such as maximum likelihood, minimum distance, nearest neighbour and condensed nearest neighbour. To examine the algorithm. Landsat Thematic Mapper (TM) data have been used to classify the crop cover in the selected region. It is clearly demonstrated that the SPC method has the higher accuracy with comparable CPU times

Acreage estimation of wheat and barley fields in the province of Adana, Turkey

In this study, the wheat (triticum) and barley (hordeum) planted areas in the province of Adana were determined by using Landsat-5 TM data in 1991. To classify the wheat and barley fields in this region, Landsat bands 3, 4 and 5 were used. Reflectance distribution in these bands has been expected to have an ellipsoidal shape, and a method was developed to make classification for such distribution. To check the accuracy of the classification, test areas in the province were selected and the classification results were compared with ground-truth. Consequently, it was found that the error estimated wheat and barley planted areas was around 15% and the results of the acreage estimation for wheat and barley fields were 218000 ± 32000 hectare in 1991. © 1995 Taylor & Francis Ltd
