Orbit and clock products for quad-system satellites with undifferenced ambiguity fixing approach
Satellite NavigationInteger Ambiguity Resolution (IAR) can significantly improve the accuracy of GNSS Precise Orbit Determination (POD). Traditionally, the IAR in POD is achieved at the Double Differenced (DD) level.

Maturing Satellite Kinematics into a Competitive Probe of the Galaxy-Halo Connection
, 2018 The kinematics of satellite galaxies moving in a dark matter halo are a direct probe of the underlying gravitational potential. Thus, the phase-space distributions of satellites represent a powerful tool to determine the galaxy-halo connection from ...

Microstructure Design of Steel‐Spinel Composites via Spark Plasma Sintering Process
Advanced Engineering Materials, EarlyView.This study illustrates how spark plasma sintering at reduced oxygen partial pressure enables controlled formation of steel‐spinel composites through tailored redox reactions and cation exchange. Comparison of the MgO–Fe2O3, steel–(MgO+Cr2O3), and steel–(MgO+Fe2O3) systems shows how oxygen activity and interface chemistry govern spinel formation, phase ...

Production of MgO/TiC Composites From MgO‐C Recyclates Using Spark Plasma Sintering
Advanced Engineering Materials, EarlyView.Using the spark plasma sintering technique, MgO/TiC composites are manufactured from recycled MgO‐C refractories stemming from the steel production that were mixed with titanium powder. This article shows, how the size of the Ti grains and their distribution in the powder mixture affect the local carbon concentration in TiC.
