Abstract Additively manufactured (AMed) titanium products are typically produced by electron beam melting (EBM), since oxidation of alloy surface can be suppressed in vacuum environment. The roughness AMed becomes more than 200 µm Rz, and the very rough would lead to reduction fatigue strength. Therefore, a post finishing process is required. Abrasive blasting one common smoothing processes met...
Using optical phase conjugation with a polarization independent periodically-poled lithium-niobate subsystem, we demonstrate dense WDM 2x10Gbit/s RZ-DQPSK transmission over 10,200km of SSMF with a record accumulated dispersion, exceeding 80,000ps/nm. 2005 Optical Society of America OCIS codes: (060.2330) Fiber optics communications; (070.5040) Phase conjugation
in this study, a landrace melon zarde jalali as the scion and commercial varieties of cucurbita rootstocks cv., shintozwa and ferro-rz was used as the rootstock. grafted plants upon commercial varieties of cucurbita with own-rooted and ungrafted at three irrigation levels of 60, 80 and 100% (respectively 4984.32, 6124.82 and 7239.41 m3ha-1) based on total available water depletion with drip irr...
RZ Cas is an Algol-type partial eclipsing binary, the secondary component of which has filled its Roche lobe. Its visual magnitude is 6.18 and its period is 1.195 days. The most important characteristics of RZ Cas are period change (due to mass transfer) and anomalies in the primary minimum of its light curve (due to δ Scuti pulsations). In this paper, light curves of RZ Cas are obtained using ...
We present a new discretization for 2D Lagrangian hydrodynamics in rz geometry (cylindrical coordinates), which is total energy conserving and symmetry preserving.
UBV ligh curves together with color curves of the semi-detached eclipsing binary RZ Cas are presented. The light curves are analyzed and the spectroscopic elements and the Hipparcos information are used to compute the absolute parameters of the system. The light curve anomalies and occasional flat minima are discussed. Based on the existing evidence, a straightforward explanation for the prim...
Konzepte der Bürgerbeteiligung sind bestrebt, die Interaktion von Bürger und Staat bzw. dessen Organen zu verbessern. Es wird beschrieben, wie unter Verwendung des Parteienstatus Elemente elektronischer und direkter Demokratie skalierbar und bürgerorientiert in eine repräsentativen Demokratie eingeführt werden können. Demokratie ist nach Preuß ([Pre89], Rz. 20) nicht der Zustand der Willensüber...
