Raising gas-dynamic stability margin of axial and centrifugal compressor stages by means of vaned diffuser boundary layer control /

open access: yesAviation, 2011
Generalised research results that consider the upgradability of axial and centrifugal gas turbine engine compressors by means of gas-dynamic boundary layer control on bladed disks are demonstrated. Active and passive methods are used.

A Sophisticated Terahertz Photonic Crystal Fiber Sensor Design for Highly Accurate Detection of Kerosene Mixtures

open access: yesAdvanced Physics Research, EarlyView.
A novel Photonic Crystal Fiber sensor with an octagonal cladding and hollow core is developed to detect kerosene adulteration. At 2.2 THz, the sensor achieves 96.80% relative sensitivity, an effective mode loss of 0.00667 cm⁻¹, and minimal confinement loss (6.78 × 10⁻8 dB m−1).

Driving automation: Learning from aviation about design philosophies [PDF]

open access: yes, 2007
Full vehicle automation is predicted to be on British roads by 2030 (Walker et al., 2001). However, experience in aviation gives us some cause for concern for the 'drive-by-wire' car (Stanton and Marsden, 1996). Two different philosophies have emerged in

High Shear Dispersion Techniques for Up‐Scaling and Controllable Cathode Morphology in High Performance Li−S Pouch Cells

open access: yesBatteries &Supercaps, EarlyView.
The effect of the blending procedure on the C−S suspension and therefore, on the Li−S battery performance is investigated. By comparing a common laboratory blender with a high shear mixing device, the higher shear forces result in a lower porosity and improved homogeneity of the electrode leading to enhanced cycle life, especially in multi‐layered ...

A novel decision support system for designing and assessing phytoremediation‐to‐biofuel value chains

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract The design of biofuel value chains is a complex process due to the large number of stakeholders involved, seasonality in feedstock availability, security of supply, logistics costs, efficiency considerations, and its multi‐node nature. Decisions on designing phytoremediation‐to‐biofuel value chains are even more complicated, due to the ...
