Interannual variability in thermal state of the upper mixed layer in the Bering Sea in winter by V. A. Luchin

“…Approximation of this coefficient dynamics with 6-degree polynomial function (polynomial trend) shows a tendencies to the mixed layer cooling in winters of 1969–1972 and 1992–2004 but the opposite tendencies to warming in 1973–1991 and 2005–2022. Variations of time coefficient for the 2nd EOF correspond to opposite tendencies in the areas with positive and negative values of this EOF. …”

EVALUATION OF SUBSOIL MASSIF STABILITY TAKING INTO ACCOUNT THE IRREGULARITY OF CONSTITUENT ROCKS ON THE BASIS OF A RANDOM SIZE AND FUNCTION MODEL by M. O. Allaev

“…The use of the random function model when solving the problem of forecasting the stability of the massif enables the evaluation of such important parameters of the safe development of the landslide process as probability of occurrence, i.e. the decrease below the permissible level of the safety coefficient, and the time period of development, so as to maintain the safety status of the massif.A method for determining the cost of maintaining the necessary stability or reliability coefficient value at a time when their calculated values are less than the respective permissible values is shown. …”
