automatic road extraction from aerial images can be very helpful in traffic control and vehicle guidance systems. most of the road detection approaches are based on image segmentation algorithms. color-based segmentation is very sensitive to light changes and consequently the change of weather condition affects the recognition rate of road detection systems. in order to reduce the light change ...
plagiarism in esl/efl learning contexts has been established as a dynamic and multi-layered phenomenon and has become a topic engaging many researchers in a heated debate in recent years. comparisons of student-generated texts with their source texts have shown that students rely on source texts in their writings and copying is a major strategy used by both l1 and l2 writers. in our country a...
In order to achieve non-cooperative target tracking and ranging in conditions of a weak echo signal, this paper presents real-time acquisition, pointing, (APT), (APTR) lidar system based on single photon detection. With system, an active APT mechanism detector is proposed. The strategy the simulation are presented. Experiments laboratory show that has good performance pointing static target, tr...
there is less published research about how teachers in efl contexts respond to students who are relatively less mature and less competent l2 writers. while writing researchers have examined various issues concerning peer and teacher response in writing-oriented classes, little research has centered on the effect of collaborative tasks particularly dictogloss on writing skills. output collaborat...
Imaging, detection and ranging of objects in the presence significant background noise is a fundamental challenge optical sensing. Overcoming limitations imposed conventional methods, quantum light sources show higher resistance against time-correlation-based illumination. Here, we introduce advantage using not only time correlations but also polarization photon pairs an object that embedded no...
