The primary objective of the Rapid Serial Visual Presentation Panel (RSVPP) was to aid in understanding the Arabic moving messages in different public places such as mosques, hospitals, factories, emergencies, malls, and markets. RSVPP is potentially useful tool for presenting important intensive information in a rapid manner. Speed of showing words in the screens, colors of fonts/backgrounds, ...

color has the ability to inspire, excite, soothe, heal and even agitate. this is particularly true for children, who can be extra sensitive to color's impact. so the importance of picking out just the right color for a young child's room shouldn't be underestimated. when choosing colors to use for your rooms home it's important to think about the mood you want to create and ...

The mechanical properties of ceramic injection molded (CIM) components are largely influenced by microstructural inhomogeneities that result from the interaction of rheological properties of the thermoplastic feedstock with machine parameters and the design of mold and injection gate. These inhomogeneities (e. g. texture, turbulences, joints, and density gradients) can form weak spots in the ma...

We demonstrate experimentally and by simulations a method for using thin nanostructured plasmonic metasurfaces to design diffractive Fresnel zone plate lenses that focus pairs of wavelengths to a single focal point. The metasurfaces are made of tightly packed cross and rod shaped optical nanoantennas with strong polarization and wavelength selectivity. This selectivity allows multiplexing two d...

We report a new electrically tunable color filter to actively adjust the correlated color temperature of white light-emitting diodes. With four passive cholesteric films and an active polarization rotator, both circular polarizations of the incident light are utilized to generate complementary blue and yellow colors. The blue/yellow ratio can be tuned by the applied voltage of the polarization ...

Broad-band photoelectric measurements on nine nights between 1969 February and 1970 February show constant intensity and colors for the pulsar of V = 16.5, B V = +o.5, U B = -0.45, and V R = -0.75, with an accuracy of 10-15 percent in each passband. The ratio of the intensity in the main pulse to that in the subpulse is about 1.8 in each color, with the same accuracy. In the passband >.>.3800-6...

Structural color is anticipated to replace pigmented or chemical due its superior saturation, resolution, environmental friendliness, and longevity. We achieve a full-color gamut of structural colors anti-counterfeit functions by an all-dielectric chiral metasurface consisting half-gammadion-shaped resonators embedded in PMMA top TiO2 layer on quartz coated with ITO layer. The prominent resonan...

Color tuning is a fascinating and indispensable property in various applications. Thus far, variety of reconfigurable approaches have been implemented to achieve color change. However, it still challenge enable continuous over the entire hue range simple, stable, rapid manner without changes configuration material properties. Here, an all-optical continuously tunable plasmonic pixel scheme demo...
