exhaust air flow will decrease, which will be cause of worse indoor climate conditions in dwelling.
The air change rate calculated on the basis of the measured flow exhaust air volume and knowledge of volume of dwelling is within the range of n = 0.18÷0.3 h-1. This value is lower than the recommended minimum of 0.5 h-1. The low value of the air change rate is the cause of high concentrations of CO2 as described earlier.
Although the assessment of air exchange in an apartment

Summary. This paper features a method of synthesizing the track irregularities by which the alignment may be analytically represented by a pseudo-stochastic function, as well as the implementation of such a method in the numerical simulation of the dynamic behaviour of the railway vehicles. The method described in Part I relies on the power spectral density of the track irregularities, as per ORE B 176 and the specifications included in UIC 518 Leaflet regarding the

In view of the preconscious behavior of pedestrian and walking speed differences, a lattice gas model of bi-direction pedestrian flow is established in this paper. According to the characteristics of pedestrian following behavior and preconscious dynamic change in different walking conditions, bi-direction pedestrian behavior model based on dynamic preconsciousness is constructed to study the bias decision-making behavior of pedestrian movement. Through numerical simulation, the influence of

From the numerical simulation method analyzes the positive pressure parallel wire between the start. This paper first parallel wire contact problem of two cables are analyzed with the classical theoretical solution and the FEM software ANSYS, to verify the

The aim of this study is to examine the strongly coupled Fluid-Structure Interaction approach as a comprehensive method of predicting the performance of the shock absorber piston valve. For this purpose, numerical simulation sand experimental testing are carried out. The coupled CFD-FEA numerical model described in this article, contrary to the attempts made so far, takes into account the influence of contact between valve discs and the initial conditions of the disc stack preload. The model is

numerical simulation to validate the experimental results. Time-frequency analysis techniques, namely Wavelet Transform (WT) and Hilbert Huang transform (HHT) are used to study the experimental signals and their performances were compared. This study provides significant insight into the problem of identifying localized damages in the structure using integrated PWAS and dispersion of multi-frequency signal after they interact with different types of damage.

This paper features a method to synthesize the track irregularities, by which the alignment may be analytically represented by a pseudo-stochastic function, as well as the implementation of such method in the numerical simulation of the dynamic behaviour of the railway vehicles. The method thus suggested allows a convenient formulation of the limits of the interval specific to the wavelengths of the track lateral irregularities, so that it will be representative for the frequency range of the
