Despite decades of research, ecologists continue to debate how spatial patterns of species richness arise across elevational gradients on the Earth. The equivocal results of these studies could emanate from variations in study design, sampling effort and data analysis. In this study, we demonstrate that the richness patterns of 2,781 (2,197 non-endemic and 584 endemic) angiosperm species along an...
Top contact organic thin-film field effect transistors based on regioregular poly(3-butylthiophene-2,5-diyl) (P3BT), poly(3-dodecylthiophene-2,5-diyl) (P3DDT) and poly(3-hexylthiophene-2,5-diyl) (P3HT) of similar concentration were fabricated by spin coating technique. The current-voltage (I-V) characteristics of these three different polymer based organic field-effect transistors (OFETs) were studied...
An organic thin film transistor (OTFT) based on chemically synthesized poly-3-hexylthiophene (P3HT) is successfully fabricated and I–V characteristics of the device is measured at room temperature. The key performance parameters such as ON/OFF ratio, threshold voltage, carrier mobility, conductivity and transconductance are extracted through the I–V characteristics of OTFT and discussed in the paper.
The object recognition problem is to determine which, if any, of a given set of objects appear in a given image or image sequence. Thus object recognition is a problem of matching models from a database with representations of those models extracted from the image luminance data. we propose a approach to the object recognition problem, motivated by the recent availability of large annotated image...
Image restoration is the process of recovering the original image from the degraded or noisy image. Blind Deconvolution Algorithm can be used where no information about PSF value, it restores image and PSF simultaneously. There are multiple noisy images for deblurring. The first task is original images are degraded by degradation model. It can be done by Gaussian Filter which is low-pass filter. The...
