Formation and microstructure of (Ti, V)C-reinforeed iron-matrix composites using self-propagating high-temperature synthesis
The combustion synthesis of (Ti, V)C-reinforced iron-matrix composites from elemental powders was examined. Examination using scanning electron microscopy indicated that two types of carbide particles were formed having a ...
The effect of deep-case oxygen hardening on the tribological behaviour of a-C:H DLC coatings on Ti6Al4V alloy
A new duplex surface treatment combining the boost diffusion oxidation (BDO) treatment with amorphous hydrogenated diamond-like carbon hard coatings (BDO/a-C:H DLC) has been developed. Experiments results demonstrated that ...
Basic architecture and sizing of commercial aircraft gas turbine oil feed systems
(The American Society of Mechanical Engineers, 2008)
The specific thrust and fuel efficiency of gas turbine engines have improved considerably over the last 20 years primarily due to technology advances in materials science and main gas path thermo-fluid analysis. However, ...
Electron-rich heteroaroylphosphonates and their reaction with trimethyl phosphite
Dialkyl heteroaroylphosphonates based on thiophene, pyrrole or furan have been prepared and their reactions with trimethyl phosphite investigated. Deoxygenation of the carbonyl groups in these heteroaroylphosphonates occurs ...
High Energy Milling of Micro Magnetic Powder for Fingerprint Development
Highly reflective magnetic powders have been available commercially for latent fingerprint development on dark background surfaces for a few years, however there are needs of a superior darker variety of the magnetic powder ...
An efficient fast mode decision algorithm for H.264/AVC intra/inter predictions
H.264/AVC is the newest video coding standard, which outperforms the former standards in video coding efficiency in terms of improved video quality and decreased bitrate. Variable block size based mode decision (MD) with ...
A Fast Intra/Inter Mode Decision Algorithm of H.264/AVC for Real-time Applications
A novel fast Intra/Inter mode decision algorithm for H.264/AVC is proposed in this paper. By reducing the calculations incurred in both intra- and inter-prediction in video encoding, the computational complexity is ...
PON topologies for dynamic optical access networks
PON-based access networks envisage the demonstration of scalability to allow gradual deployment of time and wavelength multiplexed architectures in a single-platform without changes in fibre infrastructure and also ...
