We describe the design, construction, and performance of a 4-circle in-vacuum diffractometer for resonant elastic soft x-ray scattering. The diffractometer, installed on the resonant elastic and inelastic x-ray scattering beamline at the Canadian Light Source, includes 9 in-vacuum motions driven by in-vacuum stepper motors and operates in ultra-high vacuum(More)
In this article, we develop a continuum mechanical model to simulate deformation and phase transformation processes in shape memory alloys. The model is based on a detailed description of the stored energy. Furthermore, the energy dissipation due to phase transformations is taken into account via the maximum-dissipation principle. The results from the 3D(More)
The computer simulation of space-temporal summation of post-synaptic potentials of neurone's membrane demonstrated the outstanding changes in the inner time structures of generated interspike intervals. The output time series of ISIs were studied using non-standard kind of time analysis -- recurrence plot method. Using this technique we observed phenomenon(More)
In this contribution, mathematical model for the description of solvent evaporation and noble metal crystallization in a porous medium is presented. The methodology is based on the volume-of-fluid method and the aim is validation of the model by comparing the numerical simulation results with analytical solutions for evaporation from a single pore and for(More)
Thermal plasma quantities measured by, the retarding potential analyzer (RPA) are, together with companion Pioneer Venus measurements, the first in situ measurements of the Venus ionosphere. High ionospheric ion and electron temperatures imply significant solar wind heating of the ionosphere. Comparison of the measured altitude profiles of the dominant ions(More)
Mountainous forest soils usually contain a large number of rock fragments (particle diameter >2 mm), which influence soil properties. Data characterizing hydraulic properties of these soils usually describe only the fine soil fraction (particle diameter <2 mm) properties. To quantitatively describe soil water movement in stony soils, it is necessary to(More)
A new approach to computer modelling of neuronal stochastic activity is described. The output dynamic activity which depends on the types and the number of input synapses, weights of the synaptic efficacy, the absolute refractory phase duration and threshold level is evaluated on this model in some types of Gaussian input processes. The behaviour of this(More)
