Vehicle model recognition from images is one of challenging fields for supporting intelligence transport system. Existing methods only deal with vehicle in fixed view. However, in video, rotation is occurred and it decreases performance of recognition. To overcome this problem, rectification method about skew though rotated view is needed. We employ the robust license plate detection method usi...

Contrary to what many scholars hold, a case can be made for human population reduction (the practice of artificially decreasing the number of human beings on the Earth). Robin Attfield’s, Paul Taylor’s, Arne Næss’s and J. Baird Callicott’s theories are considered for justifying human population reduction; however, only Næss’s actually justifies reduction. Another argument for human population r...

This contribution focuses on the development of a dynamic conceptual model for a batch rectifier having an infinite number of stages without resorting to multistage calculations. For a given instantaneous still composition, the key feature of the method is the estimation of the instantaneous minimum reflux or the instantaneous distillate composition by using the Rectification Body Method. The u...

Arbitrary text appearance poses a great challenge in scene recognition tasks. Existing works mostly handle with the problem consideration of shape distortion, including perspective distortions, line curvature or other style variations. Rectification (i.e., spatial transformers) as preprocessing stage is one popular approach and extensively studied. However, chromatic difficulties complex scenes...

Ion current rectification dependent on the concentration gradient of KCl solutions was systematically investigated in polyethyleneimine modified glass nano-pipettes with inner diameter of 105 nm. Peak shape dependence of the rectification factor on outer KCl solution concentration was observed when inner KCl solution with concentration from 1 mM to 500 mM was used. The peak shape dependence was...

In this paper we propose and study a simple trinocular rectification method in which stratification to projective and affine components gives the rectifying homographies in a closed form. The class of trinocular rectifications which has 6 DOF is parametrized by an independent set of parameters with a geometric meaning. This offers the possibility to minimize rectification distortion in a natura...

In this paper, we study a planar rectification technique [1] that takes perspective projection matrices obtained by selfcalibration [2]. The self-calibration takes a nonlinear estimation called the Levenberg-Marquardt method on constraints imposed by the fundamental matrix [3] to estimate the projection matrices. The rectification technique determines new perspective projection matrices by solv...

Thermal rectification is a phenomenon in which transport is preferred in one direction over the opposite. Though observations of thermal rectification have been elusive, it could be useful in many applications such as thermal management of electronics and improvement of thermoelectric devices. The current work explores the possibility of thermally rectifying devices with the use of nanostructur...

Rectification and thermal stability of diodes formed at graphene/GaN interfaces have been investigated using Raman Spectroscopy and temperature-dependent current-voltage measurements. The Schottky barriers formed between GaN and mechanically transferred graphene display rectification that is preserved up to 550 K with the diodes eventually becoming non-rectifying above 650 K. Upon cooling, the ...

The second-order processes of optical-rectification and photoconduction are well known and widely used to produce ultrafast electromagnetic pulses in the terahertz frequency domain. We present a new form of rectification that relies on the excitation of surface plasmons in metal films deposited on a shallow grating. Multiphoton ionization and ponderomotive acceleration of electrons in the enhan...
