Unsupervised classification techniques share a common intent to uncover the major land cover classes that exist in the image without prior knowledge of what they might be. Generically, such procedures fall into the realm of cluster analysis since they search for clusters of pixels with similar reflectance characteristics in a multi–band image. All of them are also generalizations of land cover ...

in the present research, susceptibility of two strawberry cultivars (selva and gavita) to bruising was studied. individual fruits were subjected to impact and compressive forces. impact forces were applied through dropping the fruits from predetermined heights as well as pendulum. bruising volume was considered as damage index. in both methods bruising severity was increased as a function of im...

soilless culture systems of strawberry production are increasing. yield and fruit quality are not only affected by growing media but also by chilling and horticultural managements. the aim of this study was to evaluate the effect of different growing media and chilling on vegetative growth, yield and fruit quality of three strawberry cultivars. the experiment was conducted in factorial experime...

Mesoamerican jaguars (Panthera onca) have been extirpated from over 77% of their historic range, inhabiting fragmented landscapes at potentially reduced population sizes. Maintaining and restoring genetic diversity and connectivity across human-altered landscapes has become a major conservation priority; nonetheless large-scale genetic monitoring of natural populations is rare. This is the firs...

In temperate trees, the extension growth history of stems and branches is easily inferred from the positions of the rings of over-wintering bud-scale scars, allowing one to assess environmental responses from surveys of saplings (Beaudet & Messier 1998, Canham 1988, King 2001). But tropical trees rarely show such distinct demarcations of growth flushes. Furthermore, the frequency of flushing ma...

We report a novel method for bubble or droplet displacement, capture and switching within a bifurcation channel for applications in digital microfluidics based on the Marangoni effect, i.e. the appearance of thermocapillary tangential interface stresses stemming from local surface tension variations. The specificity of the reported actuation is that heating is provided by an optimized resistor ...
