â in order to determine the snowfall threshold temperature in different regions of kurdistan province, first the occurrence times of the non shower snow, associated with dry-bulb temperature and dew point temperature at the time of observation were extracted for 7 synoptic stations of the province. then, the frequency, relative frequency and cumulative frequency of snowfall in different temper...
The purpose of this study is to produce a groundwater spring potential map based on statistical and probability logistic regression method. The spatial locations of the springs in mountainous Miradeh watershed, Kurdistan province, with 381 Km2 were determined. Based on field and local study and Water Resources Management Company, spatial location of 904 springs in the study area were registered...
In this paper two novel steganalysis methods is presented based on co-occurrence matrix of an image. It is shown that by using features extracted from this matrix, we can differentiate between cover and stego images. These features include energy, entropy, contrast, inverse difference moment, maximum probability and correlation. We use SVM classification for separation of cover and stego imag...
Personalization and recommendation systems require formalized model for user preference. This paper presents the formal model of preference including positive preference and negative preference. For rare events, we apply the probability of random occurrence in order to reduce noise effects caused by data sparseness. Pareto distribution is adopted for the random occurrence probability. We also p...
