We present an interface to allow for easy selection and creative control of color changing lamp fixtures in the home, using the analogy of taking a snapshot to select them. The user is presented with a GUI on their mobile phone to control light attributes such as color, brightness, and scheduling and is provided a means to specify a group of lights to be controlled at once. This is achieved usi...

Nifedipine (NIF), a 1,4-dihydropyridine calcium channel antagonist, undergoes photo-degradation to dehydro-nifedipine (DNIF) upon exposure to ultraviolet (UV) light and to the nitroso analogue of dehydro-nifedipine (NDNIF) when exposed to sunlight or some kinds of artificial lights. NIF photo-degradation products do not contribute to clinical activity, thus prevention of photo-degradation of NI...

The present work is focused on the homogeneous and heterogeneous photo-catalytic degradation of Hacid, a non-biodegradable dye intermediate from dye manufacturing industries, using Advanced Oxidation Processes (AOPs) such as UV, UV/H2O2, UV/H2O2/Fe 2+ (photo-Fenton process), UV/TiO2 and UV/H2O2/TiO2. Degradation experiments were carried out to optimize the amount of catalyst, effect of Hacid co...

nitrate is one of the pollutants of groundwater and the great amount of nitrate in drinking water can bring about some hygienic problems such as methemoglobinema phenomena in children. therefore, this research aims to study the efficiency of photo- fenton in removing nitrate and investigating the variables affecting it in aqueous solutions. this research was carried out in water and wastewater ...

The research study is based on photo catalytic technologies coupled with nano chemical for the treatment of oil produced water. Application solar energy considered to a best choice due its abundance availability throughout year round in Sultanate Oman. In recent years, process has shown have great potential as low-cost, sustainable and environmentally friendly technology. Heterogeneous photocat...

Photo collage is an effective representation for photo summarization and visualization. However, its practical usage is limited by its high computational cost. In this paper, we present efficient optimization techniques based on a novel formulation on markov random fields and several insights unexploited by previous approaches. Our method achieves up to hundreds-fold performance improvement, an...

Tungsten trioxide nanoparticles with two different sizes (average particle sizes about 50 and 80 nm) were prepared by the spray pyrolysis method. Photo degradation of Congo Red (azo dye) showed that photo catalytic property of the as-prepared WO3 nanoparticles with average size about 80 nm is higher than the sample with average size about 50 nm. Photo degradation of Rhodamine B (...
