Impact of Mining Disturbance on Highway Sustainability: A Case Study of Aleksinac Mine Area, Serbia
Underground coal mining in expansive basins has led to land subsidence, posing significant threats to the aboveground structures and the environment. Addressing this issue is paramount, necessitating accurate and reliable prediction methods.

Application of Finite Volume Method to Structural Stochastic Dynamics
The stochastic dynamic problems were becoming more difficult after considering the influences of stochastic factors and the complexity of the dynamic problems.

Stochastic approximation methods [PDF]
The methods are concerned with the problem of approximating a point of the q-dimensional Euclidian space at which a function f acquires its minimum or maximum or at which f is equal to a predetermined number. These methods are used to determine optimum conditions for concrete chemical and physical processes.

Stochastic average model methods
We consider the solution of finite-sum minimization problems, such as those appearing in nonlinear least-squares or general empirical risk minimization problems. We are motivated by problems in which the summand functions are computationally expensive and evaluating all summands on every iteration of an optimization method may be undesirable.

A class of stochastic Gronwall’s inequality and its application
This paper puts forward the basic form of stochastic Gronwall’s inequality and uses, respectively, the iterative method, the integral method and the martingale representation method to prove it.

Multidimensional Stochastic Approximation Methods
Multidimensional stochastic approximation schemes are presented, and conditions are given for these schemes to converge a.s. (almost surely) to the solutions of $k$ stochastic equations in $k$ unknowns and to the point where a regression function in $k$ variables achieves its maximum.

The main aim of this paper is to demonstrate the application of the generalized stochastic perturbation technique to model the lognormal random variables in structural mechanics. This is done to study probabilistic characteristics of the eigenvibrations
