Lagrangian temperature, velocity and local heat flux measurement in Rayleigh-Benard convection [PDF]
, 2007 We have developed a small, neutrally buoyant, wireless temperature sensor. Using a camera for optical tracking, we obtain simultaneous measurements of position and temperature of the sensor as it is carried along by the flow in Rayleigh-B\'enard ...

Yield prediction of grassland swards using specific equations for Rising Plate Meter
agricultural engineering.euAccurate prediction of grassland yield is essential for efficient management and sustainable use. The Rising Plate Meter (RPM) is a device widely used in pasture management to measure the height of growth considering sward density to calculate biomass ...

Optical guiding in meter-scale plasma waveguides
, 2020 We demonstrate a new highly tunable technique for generating meter-scale low density plasma waveguides. Such guides can enable electron acceleration to tens of GeV in a single stage.

Apparatus to control and visualize the impact of a high-energy laser pulse on a liquid target [PDF]
, 2017 We present an experimental apparatus to control and visualize the response of a liquid target to a laser-induced vaporization. We use a millimeter-sized drop as target and present two liquid-dye solutions that allow a variation of the absorption ...

A study on the effect of sward conditions on herbage accumulation during winter and spring : a thesis presented in partial fulfilment of the requirements for the degree of Master of Applied Science in Plant Science at Massey University [PDF]
, 1999 Recently there has been an increased trend for farmers to adopt farm systems that operate at a reduced stocking rate, with the aim to improve per hectare production through achieving higher production per cow.

Active folding of fluvial terraces across the Siwaliks Hills, Himalayas of central Nepal [PDF]
, 2000 We analyze geomorphic evidence of recent crustal deformation in the sub-Himalaya of central Nepal, south of the Kathmandu Basin. The Main Frontal Thrust fault (MFT), which marks the southern edge of the sub-Himalayan fold belt, is the only active ...

Hydrodynamic and mass transfer in inertial gas–liquid flow regimes through straight and meandering millimetric square channels [PDF]
, 2011 Heat-exchanger reactors are an important part of process intensification technology. For plate geometries, one solution for intensifying transfer and increasing residence times is to construct two-dimensional meandering channels.
