Testing an Online Spread Pattern Determination Sensor on a Broadcast Fertilizer Spreader [PDF]

, 2002
An alternative method for fertilizer spread pattern determination was developed based on predicting where individual fertilizer particles land on the ground, in contrast to the traditional method of collecting the particles in bins (ASAE Standard S341.2).

Correlated X-ray/Ultraviolet/Optical variability in the very low mass AGN NGC 4395 [PDF]

, 2012
We report the results of a one year Swift X-ray/UV/optical programme monitoring the dwarf Seyfert nucleus in NGC 4395 in 2008-2009. The UV/optical flux from the nucleus was found to vary dramatically over the monitoring period, with a similar pattern of ...

The circumstellar disc in the Bok globule CB 26: Multi-wavelength observations and modelling of the dust disc and envelope [PDF]

, 2009
Circumstellar discs are expected to be the nursery of planets. Grain growth within such discs is the first step in the planet formation process. The Bok globule CB 26 harbours such a young disc.

HST Observations of GRO J1655-40 in Outburst [PDF]

, 1998
We examine the results of a coordinated HST-RXTE-CGRO campaign to study the microquasar GRO J1655-40 during its 1996-7 outburst, focusing on interpretation of the overall anti-correlation seen between optical and X-ray fluxes during the early months of ...

Mean curvature and texture constrained composite weighted random walk algorithm for optic disc segmentation towards glaucoma screening

Healthcare Technology Letters, 2018
Accurate optic disc (OD) segmentation is an important step in obtaining cup-to-disc ratio-based glaucoma screening using fundus imaging. It is a challenging task because of the subtle OD boundary, blood vessel occlusion and intensity inhomogeneity.
