In order to enhance the display result of the LED display image, an improved algorithm of LED display image based on composed correction is proposed. Firstly, the correction principle and the development status of the current correction technologies of the LED display image is introduced, and the two main correction technologies are analyzed. Secondly, the theory of composed correction is propo...
The purpose of this paper is to analyze the efficiency of local governments in Belgium using a broad variety of non-parametric and parametric reference technologies. Specifically, we calculate indices of cost efficiency for five different reference technologies, two non-parametric ones (Free Disposal Hull (FDH) and variable returns to scale Data Envelopment Analysis (DEA)) and three parametric ...
Single photons are of paramount importance to future quantum technologies, including quantum communication and computation. Nonlinear photonic devices using parametric processes offer a straightforward route to generating photons, however additional nonlinear processes may come into play and interfere with these sources. Here we analyse spontaneous four-wave mixing (SFWM) sources in the presenc...
Spatial memory has been recognized as an important factor in efficient human-computer interaction. However, most previous studies are limited to very simple depth cues and 2D displays. We present a study investigating the effects of head-coupled perspective, stereoscopy and simple landmarks on spatial memory by measuring performance and accuracy in a memory game. Our results indicate that head-...
The holy-grail in terms of flat panel displays has been an inexpensive process for the production of large area ‘hang on the wall’ television that is based on an emissive technology. As such electron field emission displays, in principle, should be able to give high quality pictures, with good colour saturation, and, if suitable technologies for the production of the cathodes over large areas w...
