The present work is interested in the mathematical and numerical modeling of effects different parameters such as angle cone, length hot source radius, on thermal plume flow interaction with its surrounding. behavior guided can give us more knowledge about control applications re
Extraordinarily wide-view circular polarizers for liquid crystal displays.
A new broadband wide-view circular polarizer is proposed for high transmittance multi-domain vertical-alignment liquid crystal displays (MVA LCDs). This configuration only requires one biaxial plate in the conventional circular polarizer. The optimal film parameters are obtained

Three-dimensional anisotropic adaptive filtering of projection data for noise reduction in cone beam CT.
PURPOSE The combination of quickly rotating C-arm gantry with digital flat panel has enabled the acquisition of three-dimensional data (3D) in the interventional suite. However, image quality is still somewhat limited since the hardware has not been optimized for CT imaging. Adap
Complex 3D scan trajectories for industrial cone-beam computed tomography using a hexapod
Abstract Industrial x-ray computed tomography (CT) represents an established measurement technique in the field of nondestructive testing and dimensional metrology. However, accuracy is sometimes limited by artifacts that cannot be avoided using a standard circular scan trajector
Optical modelling of a GaAs/GaSb core–shell cone-topped octagonal-faced nanopillar array with periodic trapezoidal textured cut for high photon trapping efficiency
Light reflectance mitigation is the most crucial factor for achieving optimal photodetector performance. In this respect, light-trapping mechanisms based on nanostructures or microstructures such as nanopillars, nanocones and nanopyramids have emerged promising candidate reducing
Controlling near-field focusing of a mesoscale binary phase plate in an optical radiation field with circular polarization
Binary Fresnel zone plates (ZP) are one of the most frequently used focusing elements inplane optical schemes in micro- and nanophotonics. With a decrease diameter focal distance ZP to meso-wavelength sizes, parameters region begin be significantly influenced by features design (
Object reconstruction by incorporating geometric constraints in reverse engineering
This paper deals with the constrained reconstruction of 3D geometric models of objects from range data. It describes a new technique of global shape improvement based upon feature positions and geometric constraints. It suggests a general incre- mental framework whereby constrain
Living on the edge: Phase transitions in convex programs with random data
Recent empirical research indicates that many convex optimization problems with random constraints exhibit a phase transition as the number of constraints increases. For example, this phenomenon emerges in the `1 minimization method for identifying a sparse vector from random lin
The Complexity and Origins of the Human Eye: A Brief Study on the Anatomy, Physiology, and Origin of the Eye
The human eye has been the cause of much controversy in regards to its complexity and how the human eye came to be. Through following and discussing the anatomical and physiological functions of the eye, a better understanding of the argument of origins can be seen. The anatomy o
