Artificial lighting accounts for approximately twenty to twenty five percent of all electrical energy usage in the United States. This is surpassed only by the energy consumption of electric machinery. Artificial lighting is a requisite for virtually all activities in residential, commercial, and industrial settings. Whether it is in the area of design, manufacture, application, maintenance, or...

Aspects of classroom lighting and décor that can promote discomfort and impair task performance through glare, and imperceptible 100 Hz flicker from fluorescent lighting, were examined in a sample of UK schools. In 90 classrooms, across eleven secondary schools and six local education authorities variables measured included flicker, illuminance at desks, and luminance of whiteboards. Results sh...

The declarative design of graphics lies at the core of the Smart Graphics research agenda. For 3D graphics the number of lights included, and the properties of these lights, has an enormous impact on what a viewer can judge about the content (the objects), properties (the geometric characteristics and spatial relations of the objects) and other aesthetic qualities of a scene. The traditional ap...

In this report, we present an extensive dataset of 96 video streams with ground truth. It includes various geometric changes, lighting conditions, and levels of motion blur, and can be used as testbed for a variety of algorithms in the context of visual tracking. We then use this dataset for a detailed quantitative evaluation of popular interest point detectors, which, in contrast to existing e...

In traditional media such as sculpture and painting, but also in film, a static design process is used during the creation phase. In interactive media dramaturgy can permanently change depending on user interaction or dynamic factors. To be consequent visualizations should react on narration changes, so that narrative content and visualization are consistent. Fig. 1: Visual Artists use graphica...

This paper presents an improved power quality converter (IPQC) based power supply design for high brightness Light Emitting Diode (HB-LED) low power lighting. The IPQC circuit uses a Cuk buck-boost converter to operate it in discontinuous conduction mode (DCM) using voltage follower technique for the mitigation of harmonic contents present in the AC mains current. Subsequently reduction in harm...

A novel OLED (organic light emitting diode) lighting panel, which uses a special layout design, can reduce the photolithography cycles and process costs and is more reliable. It only needs two steps of photolithography cycles, which include an ITO (InSnO compound transparent oxide) pattern and insulator pattern. There is no need for the metal bus pattern of the ordinary design. The OLED device ...

L ighting design is an important topic of game development. There are many functions that lighting assumes in game environments, including directing attention, establishing good action visibility, evoking emotions, setting atmosphere, and providing depth. Current lighting design techniques rely on static manually designed lighting, where designers set up the positions, angles, and colors for ea...
