X-Light is an open-source software that written in Python with a graphical user interface. was developed to determine residual stress by X-ray diffraction. This can process the 0D, 1D and 2D diffraction data obtained laboratory diffractometers or synchrotron radiation. provides several options for analysis five functions fit peak: Gauss, Lorentz, Pearson VII, pseudo-Voigt Voigt. The determined ...

We investigate transmission problems between a (thermo-)viscoelastic system with Kelvin-Voigt damping, and a purely elastic system. It is shown that neither the elastic damping by Kelvin-Voigt mechanisms nor the dissipative effect of the temperature in one material can assure the exponential stability of the total system when it is coupled through transmission to a purely elastic system. The ap...

We have developed an alternative FRD empirical model for the parallel laser beam technique which can accommodate contributions from both scattering and modal diffusion. It is consistent with scattering inducing a Lorentzian contribution and modal diffusion inducing a Gaussian contribution. The convolution of these two functions produces a Voigt function which is shown to better simulate the obs...

Recently, there is an increasing body of evidence supporting the clinical importance of assessment of regional myocardial function as an essential tool for the evaluation of heart disease (Helm et al. 2005; Voigt et al. 2004, Liel-Cohen et al. 2010). In particular, numerous reports support the notion that diagnosis and management of coronary heart disease require the ability to adequately asses...

The desired results of variable topology material layout computations are stable and discrete material distributions that optimize the performance of structural systems. To achieve such material layout designs a continuous topology design framework based on hybrid combinations of classical Reuss (compliant) and Voigt (sti ) mixing rules is investigated. To avoid checkerboarding instabilities, t...

Different angiographic techniques (e.g., multiple oblique views, angiotomography, and magnification angiography) have been proposed to improve the diagnosis of cerebral vascular malformations and occlusive diseases. However, these methods are either time-consuming or necessitate repeated injections of contrast medium. The common goals of all these techniques are (1) to achieve a documentation o...

Results of birefringence experiments on aqueous solutions of charged poly(styrenesulfonate) (PSS) with different molecular weights between 10~ and I-I x 10~

We report on high-resolution observations (ℜ ≃ 45000) of the Hubble Deep Field South QSO J2233-606 obtained with the VLT UV-Visual Echelle Spectrograph (UVES). We present spectral data for the wavelength region 3050 < λ < 10000Å. The S/N ratio of the final spectrum is about 50 per resolution element at 4000Å, 90 at 5000Å, 80 at 6000Å, 40 at 8000Å. Redshifts, column densities and Doppler widths ...
