On-the-go data collection yields spatially referenced information at a sub-field scale that is needed for many applications like precision farming. A spatial offset occurs between sensor and position measurements if the GPS-antenna is not placed on top of the sensor. To correct for such an offset, we present a kinematic model that accounts for the mechanisms underlying the offset. The model was...

While multicore architectures are becoming usual on desktop machines, supercomputers are approaching million cores. The amount of memory and compute power on current clusters enable us e.g. to obtain a resolution of in excess (10 000)=10 degrees of freedom. However, on the downside we are forced to partition our domain into extremely many sub-problems. Portions of the algorithm that do not perm...

Antheraea assama, an economically important and scientifically unexplored Indian wild silkmoth, is unique among saturniid moths. For this species, a total of 87 microsatellite markers was derived from 35 000 expressed sequence tags and a microsatellite-enriched sub-genomic library. Forty individuals collected from Tura and West Garo Hills region of Northeast India were screened for each of thes...

Poisoning is a common medico social problem now a days. The scale of the problem is enormous due to the increased incidence of morbidity and mortality (1). Poisoning is a significant global public health problem. According to the World Health Organization (WHO) data in 2004 an estimated 346 000 people died worldwide from unintentional poisoning of which 91% occurred in lowand middle-income coun...

We report the observation of whispering gallery modes (WGM) in high quality GaAs/AlAs pillar microcavities defined by electron-beam lithography and electron cyclotron resonance reactive ion etching. Photoluminescence experiments, conducted using InAs quantum dots as an internal probe, reveal a remarkably simple WGM spectrum, consisting of a single series of TE modes. For diameters ranging from ...

The problem of accurate determination of the position, orientation and width of involute spur gear teeth using a single front-lit image is addressed. The information is used to compute global measures of tooth concentricity and pitch variations across a gear wheel. The approach is based on the use of specialised filters which make maximum use of the grey level information available in the image...
