Accurate, precise, and timely estimation of crop yield is key to a grower’s ability proactively manage growth predict harvest logistics. Such predictions typically are based on multi-parametric models in-situ sampling. Here we investigate the extension greenhouse study, low-altitude unmanned aerial systems (UAS). Our principal objective was snap bean (Phaseolus vulgaris) using imaging spectrosc...

The Angel-Devil game is an infinite game played on an infinite chess board: In each move the Angel, a generalized chess king, jumps from his current square to some location at distance at most k, while his opponent, the Devil, blocks squares trying to strand the Angel. The Angel wins if he manages to fly on forever. It is a long-standing open question whether some Angel of sufficiently large po...

Among the possible variants of X-Ray Fluorescence (XRF), applications exploiting scanning Macro-XRF (MA-XRF) are lately widespread as they allow visualization element distribution maintaining a non-destructive approach. The surface is scanned with focused or collimated X-ray beam millimeters less: analyzing emitted fluorescence radiation, also elements present below contribute to elemental imag...

an ideal fusion method preserves the spectral information in fused image without spatial distortion. the pca is believed to be a well-known pan-sharpening approach and being widely used for its efficiency and high spatial resolution. however, it can distort the spectral characteristics of multispectral images. the current paper tries to present a new fusion method based on the same concept. in ...

This paper presents an overview of three approaches developed in Matlab for geospatial analysis of images. GeoEtrim has two subpackages, GeoSpot and GeoFigcon. GeoSpot aims to perform bundle adjustment of stereo linear array remotely sensed images considering their interior and exterior orientation parameters. The correlation among orientation parameters, their validation and efficiency on the ...

Early in its mission, the Landsat-7 spacecraft was temporarily placed in a ‘‘tandem’’ orbit very close to that of the Landsat-5 spacecraft in order to facilitate the establishment of sensor calibration continuity between the Landsat-7 Enhanced Thematic Mapper Plus (ETM+) and Landsat-5 Thematic Mapper (TM) sensors. The key period for the tandem configuration was June 1–4, 1999, during which hund...

the study area is located in the central iranian tectono-magmatic zone, which is known for its world-class ioa-type iron ore deposits. the advanced space borne thermal emission and reflection radiometer (aster) and landsat enhanced thematic mapper plus (etm+) image-processing techniques, were used in satellite imagery through conventional and also modern processing methods including band ratios...

This is a personal account of my observation of events associated with stem cells in recent years during my stays in Singapore, Malaysia, Canada, Hong Kong and China. It is based on my notes on the news about stem cells from reports broadcast on television, newspapers, magazines and medical journals. It is my perception that the current large amount of news on the developments and applications ...
