At this time, a large number of hydraulic turbomachinery installations are ageing, so that they need refurbishement to increase their efficiency and their associated output power. The items that need refurbishement are mainly the runner and the guide vanes ...
We present comparisons of theoretical and simulation results for static and dynamical correlation functions for a very simple model of attractive colloidal systems, the short-ranged square-well potential. In the region of the phase diagram investigated, th ...
In this paper, an analysis of electric and magnetic fields radiated by lightning first and subsequent return strokes to tall towers is presented. The contributions of the various components of the fields, namely, static, induction, and radiation for the el ...
For the first time this paper presents strip lines fabricated using SU-8 as the dielectric material. It shows the complete fabrication process of micromachined strip lines with a total height of 35.5 um as well as their characterization by on-wafer S-param ...
The incipient ferroelectric KTaO3 presents low-T Brillouin spectra anomalies, e.g. a broad central peak (CP), and some additional Brillouin doublets (BD). whose origin are interpreted in terms of phonon-density fluctuation processes. A parameterisation fro ...
The treatment of kinetic shear Alfven waves in homogeneous magnetized plasmas by means of Vlasov simulation is examined. To this end, the driftkinetic version of the Vlasov-Maxwell equations is solved via various numerical schemes, all employing a grid in ...
We analyze the room temperature photoluminescence properties of several multilayer stackings of GaN/AlN quantum dots. We report drastic differences of emission energies and linewidths between continuous wave and time-resolved photoluminescence experiments. ...
Introduction: In this study the effect of subthalamic nucleus neep brain Stimulation (STN-DBS) on the gait parameters of patients with Parkinson's disease (PD) was examined using an ambulatory gait analysis system based on miniature gyroscopes. The aim was ...
Parallel computation of blood flow in a 1D model of human arterial network has been carried out employing a Taylor Galerkin finite element method. Message passing interface libraries have been used on Origin 2000 SGI machine. A Greedy strategy for load-dis ...
Aortic compliance and pulse wave velocity (PWV) are important determiners of heart load, and are clinically useful indices of cardiovascular risk. Most direct methods to derive them require invasive pressure measurement. In this work a noninvasive techniqu ...
