In Situ Micromechanical Study of Bimodal γ′–γ″ Precipitate Assemblies in Ni–Cr–Al–Nb Superalloy
Advanced Engineering Materials, EarlyView.A Ni–Cr–Al–Nb superalloy with a bimodal γ′–γ″ precipitate distribution is developed. Composite precipitate assemblies form through heterogeneous nucleation, effectively impeding dislocation motion. Micropillar compression reveals high strength at room and elevated temperatures, governed by precipitate shearing, with coupled faulting mechanisms ...

On the covering radius of a code and its subcodes
, 1990 Let C0 be a subcode of codimension i of a binary code C. We show that the covering radius ϱ(C0) of C0 and the covering radius ϱ(C) ofC satisfy ϱ(C0)⩽ϱ(C)(i+1)+i. When i 1, we determine the exact range of values for ϱ(C0) and ϱ(C).

A note on the covering radius of optimum codes
, 1991 This paper gives a lower bound and an upper bound for the covering radius of optimum codes. The upper bound so obtained is better than other known upper bounds, restricted to optimum codes.

WCDMA Uplink Interference Assessment from Multiple High Altitude Platform Configurations
EURASIP Journal on Wireless Communications and Networking, 2008 We investigate the possibility of multiple high altitude platform (HAP) coverage of a common cell area using a wideband code division multiple access (WCDMA) system. In particular, we study the uplink system performance of the system.

Advanced Engineering Materials, EarlyView.Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...

Covering radius and the chromatic number of Kneser graphs
, 1990 Let C be a binary linear code with covering radius R and let C0 be a subcode of C with codimension i. We prove that the covering radius R0 of C satisfies R0 ⩽ 2R + 2i − 1, by setting up a graph coloring problem involving Kneser ...

Advanced Engineering Materials, EarlyView.A distinct semi‐confined inner‐tube chemical vapor deposition geometry enables reproducible, large‐area growth of phase‐pure 2D β′‐In2Se3 from InI + Se precursors. Engineering local vapor transport and optimizing precursor delivery and temperature–time conditions yield uniform continuous films.
