In this paper, we present a stylized dynamic interdependent multi-country energy transition model. The goal of this paper is to provide a starting point for examining the impact of uncertainty in such models. To do this, we define a simple model based on the standard Solow macroeconomic growth model. We consider this model in a two-country setting ...

We consider two-phase flow in a porous medium composed of two different rock types, so that the capillary pressure field is discontinuous at the interface between the rocks. This is a nonlinear and degenerate parabolic problem with nonlinear and discontinuous transmission conditions on the interface. We first describe a space-time domain decomposit...

We extend below a limit theorem [3] for diffusion models used in population theory. A diffusion with small noise is defined as the solution of a stochastic differential equation (SDE) driven by standard Brownian motion B t (·) (defined on a probability space and progressively measurable with respect to an increasing filtration) dX ε t...

In order to maximize the efficiency of telecommunications equipment, it is necessary that the radio frequency (RF) power amplifier is situated as closely as possible to its compression point. This makes its response nonlinear, and therefore it is necessary to linearize it, in order to minimize the interference that nonlinearities cause outside the ...

Magistrsko delo obravnava problematiko vibracijskih bolezni in s tem povezano problematiko karakterizacije biodinamskega sistema, prsta na roki. Natančneje se osredotoči na določitev parametrov togosti povezav numeričnega modela prsta na roki. V delu predstavimo razvit algoritem za določitev optimalne ravnovesne lege sistema v procesu identifikacij...

Admixtures are commonly used nowadays in the mix composition of concrete. These additions affect concrete properties and performance especially creep deformations. This paper shows the effect of admixtures on creep of concrete. In fact, creep deformations have prejudicial consequences on concrete behaviour; an incorrect or inaccurate prediction lea...

In this research the tail equivalent linearization method (TELM) has been extended to study structures with degrading materials. The responses of such structures to excitations are non-stationary, even if the excitations are stationary. Non-stationary behavior of the system cannot be considered by conventional TELM. Applying the conventional TELM, ...

Let h be a complex commutative subalgebra of the n×n matrices Mn(ℂ). In the algebra MPsd of matrix pseudodifferential operators in the derivation ∂, we previously considered deformations of h[∂] and of its Lie subalgebra h[∂]>0 consisting of elements without a constant term. It turned out that the different evolution equations for the generators of...

The primary goal of the present paper is to argue for the hypothesis that labeling is required for linearization, which is called Labeling for Linearization (LfL). To achieve this goal, it is first argued that labels are not necessary for semantic interpretation. It is then proposed that labels are necessary for linearization at the PF-interface in...
