The QBF Gallery 2014 was a competitive evaluation for QBF solvers organized as part of the FLoC 2014 Olympic Games during the Vienna Summer of Logic. The QBF Gallery 2014 featured three different tracks on formulas in prenex conjunctive normal form (PCNF) including more than 1200 formulas to be solved. Gold, silver, and bronze track medals were awarded to the solvers that solved the most formul...

As stated in its mission, "the strength of the National Gallery of Canada lies in its collection of art, especially Canadian art, and its accessibility to the public across the country." Founded in 1880, the National Gallery of Canada now includes over 42,000 objects of fine and decorative art, of which only a small proportion is shown either in permanent installations or temporary exhibitions....

We report a theoretical study showing that rogue waves can emerge in whispering-gallery-mode resonators as the result of the chaotic interplay between Kerr nonlinearity and anomalous group-velocity dispersion. The nonlinear dynamics of the propagation of light in a whispering-gallery-mode resonator is investigated using the Lugiato-Lefever equation, and we give evidence of a range of parameters...

The Art Gallery Problem (AGP) is a well studied NPhard problem in Computational Geometry. It consists of finding the minimum number of guards that are sufficient to visually cover a gallery, represented by a polygon. In our work, we designed and implemented a method that is capable of solving complex instances with up to 5000 vertices within only a few minutes. Also, we provide a complete versi...

We demonstrate the quality factor Q - (0.8 +/- 0.1) x 10(10) of whispering-gallery modes in fused-silica microspheres at 633 nm, close to the ultimate level determined by fundamental material attenuation as measured in optical fibers. The lifetime of ultimate Q is limited by adsorption of atmospheric water. Monitoring of adsorption kinetics with submonolayer sensitivity by Q factors and frequen...

Two dimensional resonators with a smooth strictly convex boundary are known to possess a whispering gallery region supporting modes concentrated near the boundary. A new class of asymmetric resonant cavities is introduced, where a whispering gallery-like region is found deep inside the resonator. The construction of such resonators is a novel application of the geometric control methods. The re...

This paper describes a set of two applications comprising the Virtual Art Gallery tool: the Space Picker application and the Virtual Exhibition Builder application. The purpose of this tool is to allow users to interactively create a virtual exhibition of artworks in a pre-built virtual model. We use X3D for the models and Java with Xj3D for the display and handling. The works of art are handle...

Customer satisfaction is the most important thing used to attract consumers today. a consumer's feeling of liking or disliking product after comparing results with his expectations.The aim this research find out which product, price, promotion and place/location dominantly influence purchasing decisions at Zea Zahera Manna Furniture Gallery in South Bengkulu. This study uses quantitative method...

At present, the most effective way to deal with the demographic shift of elders is encouraging them to live in nursing homes for more effective health care. However, such move dramatically increases their risk of social isolation. A contextual inquiry in a local nursing home revealed that most elderly people have few connections with the outside environment because of their decreased mobility a...

An analytical study was carried out to investigate the performance of an oil supplying system of a variable speed compressor using a commercial CFD program. The simulations for the oil supplying system with the oil and air mixture were performed by varying compressor speed from 40 Hz to 90 Hz. Comparing the predicted with the measured data on the modified scroll compressor validated the simulat...
