The coupled damage/plasticity model for meso-level which is ply-level in case of Uni-Directional (UD) Fiber Reinforced Polymers (FRPs) is implemented. The mathematical formulations, particularly the plasticity part, are discussed in a comprehensive manner. The plastic potential is defined in effective stress space and the damage evolution is based on the theory of irreversible thermodynamics. T...

The paper analyzes the government budget cost of credit guarantees and subsidies. The analysis is done both in a general qualitative manner and quantitatively for the case of Czech Supporting and Guarantee Agricultural and Forestry Fund (SGAFF). In the quantitative part of the paper we show that the portfolio of the SGAFF has a sufficient value to cover expected costs of credit guarantees and s...

We study the optimal anticipated policy in a pure-currency economy with flexible prices and a nondegenerate distribution of money holdings. The economy features a business cycle and lump-sum monetary injections have distributional effects that depend on the state of the cycle. We parsimoniously characterize the dynamics of the economy and study the optimal regulation of the money supply as a fu...

We study a business cycle model in which a benevolent fiscal authority must determine the optimal provision of government services, while lacking credibility, lump-sum taxes, and the ability to bond finance deficits. Households and the fiscal authority have risk sensitive preferences. We find that outcomes are affected importantly by the household’s risk sensitivity, but not by the fiscal autho...

Over the past decade or so, many private and publicly held companies have moved away from providing employees with company-funded pensions upon retirement to a retirement system that requires both employee and company contributions to fund an individual’s retirement. These so-called 401(k) retirement plans usually require the employee to choose among different investment vehicles, including mut...

Co-location is compatible with the doctrine of microphysical supervenience. Microphysical supervenience involves intrinsic qualitative properties that supervene on microphysical structures. Two different objects, such as Socrates and the lump of tissue of which he is constituted, can be co-located objects that supervene on different sets of properties. Some of the properties are shared, but oth...

Fluidized bed techniques are employed in coal combustion power plants, because they allow for the use of low-quality fuel and result in low pollutant emissions. The most important dynamical difference between fluidized beds and normal combustion chambers, is that the former are characterized by a significant loading of carbon, usually absent in conventional plants. Fluidized beds are remarkably...

Lumped Parameter Model is well known in solving high frequency signal propagation in high voltage transformer windings. At Southampton University, the modelling technique has been improvised and employed to solve partial discharge (PD) problem occurred within deep inside transformer windings. Firstly, a lumped capacitive parameter model was considered and secondly a transmission line lumped par...

In order to increase the accuracy of evaluating seismic response of structures, it is critical to conduct dynamic analyses based upon precise nonlinear models being as consistent as possible with the real conditions of corresponding structures. The concentrated plasticity model including one elastic element and two nonlinear spring elements at both ends has been considered within the research c...
