Current rectification effect in an asymmetric molecule HCOO-C6H4-(CH2)n sandwiched between two aluminum electrodes has been studied using an ab initio nonequilibrium Green's function method. The conductance of the system decreases exponentially with the increasing number n of CH2. The phenomenon of current rectification is observed such that a very small current appears at negative bias and a s...

The thesis presents rectification methods of an omnidirectional stereo pair. Several methods are developed and a novel rectification method called stereographic rectification is introduced. In the second part of the thesis, a method of 3D reconstruction from a stereo pair rectified using an arbitrary method of the adduced methods is presented. Further, a method of judging the accuracy of an ess...

A common feature of neuronal nicotinic acetylcholine receptors (nAChRs) is that they conduct inward current at negative membrane potentials but little outward current at positive membrane potentials, a property referred to as inward rectification. Physiologically, inward rectification serves important functions, and the main goal of our study was to investigate the mechanisms underlying the rec...

Electrical rectification was demonstrated in whole sartorius muscle and sciatic nerve of Rana pipiens and also in the single giant nerve fiber of the northern squid, Ommastrephes illecibrossus. It is probably a property of the plasma membrane. Rectification decreases reversibly under the influence of increased concentrations of the potassium ion and with chloroform, veratrine sulfate and isoamy...

At present, HRSI (High-resolution Satellite Imagery) is more and more widely applied for surveying, land, constructing, production and living field, and it becomes increasingly important to acquire orthophotograph by processing geometric rectification of satellite original images. Less or without GCPs (Ground Control Points) in several parts of area is a puzzled problem for remote sensing image...

We describe the geometry, constraints and algorithmic implementation for metric rectification of planes. The rectification allows metric properties, such as angles and length ratios, to be measured on the world plane from a perspective image. The novel contributions are: first, that in a stratified context the various forms of providing metric information, which include a known angle, two equal...
