With progress in mineral processing technologies, particle size classification equipment has also been changed to satisfy the needs of modern plants. Accordingly, design, manufacturing and utilizing of banana screens in mineral processing plants have led to increased screening efficiency at industrial scale. Banana screen is an important invention occurred in past decade which increases screeni...

A room-sized, walk-in virtual reality (VR) display is to a typical computer screen what a supercomputer is to a laptop computer. It is a vastly more complex system to design, house, optimize, make usable, and maintain. 17 years of designing and implementing room-sized ‘‘CAVE’’ VR systems have led to significant new advances in visual and audio fidelity. CAVEs are a challenge to construct becaus...

One of the major challenges in scanning and printing documents in a digital library is the preservation of the quality of the documents and in particular of the images they contain. When photographs are offset-printed, the process of screening usually takes place. During screening, a continuous tone image is converted into a bi-level image by applying a screen to replace each colour in the orig...

A method of coding scanned documents containing halftone pictures, e.g. newspapers and magazines, for transmission purposes in prepress is proposed. The halftone screen is estimated and the grey value of each dot is found, thus giving a compact description. At the receiver the picture is re-screened. A new data structure and related algorithms for handling the digital screen without restriction...

Over the centuries, stories have moved from the physical environment (around campfires and on the stage), to the printed page, then to movie, television and computer screens. Today, using wireless and tag sensing technologies, researchers and storytellers are able to bring digital stories back into our physical environment. The Tangible Viewpoints system explores how physical objects and augmen...

Digital visual effects emerged onto cinema screens during the mid-20th century and have now become an essential feature of contemporary film television production. Notwithstanding rise prominence in telecinematic discourse as a key storytelling tool, there is currently gap audiovisual archival collections, digital void documented memory television. Why are no records our moving image archives?&...

Background: It has been shown that short-wavelength blue component of the visible light spectrum can alter the circadian rhythm and suppress the level of melatonin hormone. The short-wavelength light emitted by smartphones’ screens can affect the sleep quality of the people who use these devices at night through suppression of melatonin.Objectives: In this study, we examined the effects of co...

Chroma screens is a term for the green and blue used in filmmaking, television, graphics during image making compositing of other images post-production. Engaging an agential realist framework to deliberate on this mode wherein they are without images, I consider chroma through material-discursive practices argue that colors can be considered cultural enactment racialized media practices. take ...
