eROSITA on SRG

Astronomische Nachrichten, 2017
eROSITA (extended ROentgen Survey with an Imaging Telescope Array) is the core instrument on the Russian–German Spectrum‐Roentgen‐Gamma (SRG) mission, which is currently scheduled for launch in late 2017. eROSITA will perform a deep survey of the entire X‐ray sky.

Registration of ‘UI SRG’ Wheat

Journal of Plant Registrations, 2012
Developing wheat ( Triticum aestivum L.) cultivars with high yield, desirable end‐use quality, and resistance to prevalent diseases are the major goals for the breeding programs in the Pacific Northwest region of the United States and the world. ‘UI SRG’ (Reg. No. CV‐1066, PI 660546) hard red

Effectiveness of SRG in Shear Strengthening of Deep and Slender Concrete Beams [PDF]

Structures
This study investigates Steel-Reinforced Grout (SRG) jackets’ efficiency in enhancing the shear strength in Reinforced Concrete (RC) beams with various shear span-to-depth (a/d) ratios, comparing them with Carbon Fabric Reinforced Cementitious Mortars ...

SRG-Disjoint Design with Dedicated and Shared Protection

2011
We consider a one layer network design problem in the presence of Shared Risk Groups (SRGs).We can define an SRG as a set of links of the logical layer that simultaneously fail in the case of a failure of a lower layer.We propose a mathematical model for the dedicated protection and two alternative models for the shared protection, all based on flow ...

ART-XC / SRG overview

Space Telescopes and Instrumentation 2018: Ultraviolet to Gamma Ray, 2018
ART-XC is an X-ray grazing incidence mirror telescopes array onboard the Spectrum-Roentgen-Gamma (SRG) mission, that is currently scheduled for launch in March 2019. This instrument was developed by the Space Research Institute (IKI) and the All-Russian Scientific Research Institute for Experimental Physics (VNIIEF).

SRG/eROSITA in-flight background at L2

Space Telescopes and Instrumentation 2020: Ultraviolet to Gamma Ray, 2020
eROSITA aboard the Spectrum-Roentgen-Gamma satellite, successfully launched in July 2019, is the first X-ray astronomical telescope operational at the Sun-Earth Lagrange point L2. A prime scientific goal of eROSITA is the detection of 100000 clusters of galaxies, which at the fainter luminosity end appears as weak and slightly extended objects. For a

Numerical Modelling of the Experimental Response of SRG Systems

Key Engineering Materials, 2019
Modern repairing and retrofitting methods for existing structures make use of composite materials, consisting of high strength textiles and a matrix, which can be either polymeric or inorganic. These kinds of techniques have been largely applied to masonry structures, since they significantly improve structural performance with a small increase of ...

A novel converter to enhance SRG performance

The 5th Annual International Power Electronics, Drive Systems and Technologies Conference (PEDSTC 2014), 2014
This paper presents a novel approach to increase the excitation flux in magnetizing state and prolong stored energy discharge in a Switched Reluctance Generator (SRG). This purpose is achieved by using a multi-winding SRG in which the coils in every phase can be paralleled in magnetization period and then shift to series connection in demagnetizing ...

Die Visionäre der SRG

2015
Die SRG hat es verstanden, den technologischen Wandel und den trägen Rechtssetzungsprozess gleichzeitig zu ihrem Vorteil zu nutzen. Mit einer Vorwärtsstrategie hat sie Fakten geschaffen, die ihre Zukunft sichern - auf Kosten des demokratischen Prozesses. [https://www.schweizermonat.ch/subscription_visitor/die-visionaere-der-srg]

SRG configurations

2018
A (v_r, b_k) configuration is an incidence structure with v points and b lines, with r lines through any point and k points on any line, and at most one line through every pair of points. The point graph of a configuration has the v points as vertices and edges between pairs of points that are collinear. The line graph is defined dually.
