MODERN SURVEILLANCE RADAR FOR AIR TRAFFIC CONTROL [PDF]
Fiabilitate şi Durabilitate, 2020 . In this paper, we focus on the approach of increasing RCS, therefore the size of RCS also includes the fact that not all radiated energy will reach the target.

A Family of Sodium Solid‐State Electrolytes Based on the NaGaxAl1‐xCl4 Solid Solution
Advanced Materials Interfaces, EarlyView.ABSTRACT Sodium‐based metal chloride solid electrolytes are promising for sodium solid‐state batteries due to their excellent oxidation stability, which, as shown for Li halides, can coexist with high ionic conductivity. To explore cationic substitution effects, we synthesized NaGaxAl1‐xCl4 (0 ≤ x ≤ 1) via ball milling and investigated structural and ...

Polyhedral Surfaces of High Genus [PDF]
, 2008 The construction of the COMBINATORIAL data for a surface with n vertices of maximal genus is a classical problem: The maximal genus g=[(n-3)(n-4)/12] was achieved in the famous ``Map Color Theorem'' by Ringel et al. (1968). We present the nicest one of Ringel's constructions, for the case when n is congruent to 7 mod 12, but also an alternative ...
