The occurrence of cycle slips is a major limiting factor for achievement of sub-decimeter accuracy in positioning with GPS (Global Positioning System). In the past, several authors introduced a method based on different combinations of GPS data together with Kalman filter to solve the problem of the cycle slips. In this paper the same philosophy is used but with discrete wavelet transforms. For...

introduction : activated protein c (apc) inactivates factor v by cleavage of its heavy chain at arg306, arg506, arg679, and lys994. mutational changes, which abolish apc cleavage sites, may predispose thrombosis by altering the inactivation process of factor v.  factor v leiden (arg506glu) has been demonstrated as a strong risk factor for thrombosis. in the current study, we have studied whethe...

land surface temperature (lst) is an important factor in global change studies. the information about lst has an important role in the range of issues and themes in earth sciences such as global environment change, human-environment interaction and more specifically to urban climatology. this research has been undertaken to analyze the potential of multispectral satellite data for retrieving th...
