IMPLEMENTATION OF READY-MADE HYDROSTATIC DELAY PRODUCTS FOR TIMELY GPS PRECIPITABLE WATER VAPOR RETRIEVAL OVER COMPLEX TOPOGRAPHY: A CASE STUDY IN THE TIBETAN PLATEAU

For the timely retrieval of global positioning system based precipitable water vapor (GPS-PWV) over complex topography when there is no in situ pressure-derived zenith hydrostatic delays (ZHDs), this article evaluates three types of ready-made ZHD products, including two newly released products from the Vienna University of Technology (TU Wien, TUW

A review of the main methods of disposal of waste containing polychlorinated biphenyls (PCBs) is presented.It is shown that a reliable, environmentally friendly and efficient process does not exist, sex shop arles and, apparently, it is impossible to create a completely environmentally friendly process.Analysis of the benefits and advantages of tec

Introduction.The mathematical model of the abutment tooth is the starting point of the finite element analysis of stress and deformation of dental structures.The simplest and easiest way is to form a model according to the literature data of dimensions and morphological characteristics of teeth.Our method is based on forming 3D models using standar
