Smoke management system is proposed for life safety in karaoke establishments. Arguments are supported by simulating different scenarios with a two-layer zone model. A typical room-corridor structure of a karaoke establishment is selected. Different ventilation arrangements are considered. With careful design such as adequate extraction rates, smoke layer in the corridor can be kept at high lev...

We present an autonomous algorithm for 3d reconstruction from a single image of an indoor scene. Most work on 3d reconstruction from vision uses multiple images (for example, binocular vision/stereopsis), and recovers depths using triangulation. However, the range at which binocular vision is accurate is limited by the “baseline” distance between the two cameras. In contrast, humans are often a...

introduction: the effect of education on esthetic perception is still unclear. this study aims to compare the perception of smile esthetics, under various conditions, among general and specialist dentists. materials and methods: a photograph of a woman’s smile was digitally altered using a software image editing program. alterations were made tothe dental midline, anterior gingival display, buc...

‘Footprints’ are marks or features of a design that alert the analyst to the possible existence of usability difficulties caused by violations of design principles. PUMA Footprints make an explicit link between the theory underlying a Programmable User Model and the design principles that can be derived from that theory. While principles are widely presented as being intuitively obvious, it is ...

The present study sought to verify the utility and reliability of footprint dimensions in sex determination in a Ghanaian population. Bilateral footprints were obtained from 126 Ghanaian students (66 males and 60 females) aged 18-30 years at Koforidua Polytechnic using an ink pad and white papers. Seven dimensions-length of each toe (designated T1-T5) from the most anterior point of the toe to ...

In relativistic heavy-ion collisions, the system has gone through a series of evolution, almost at every stage of its evolution it leaves behind footprints in flow observable. Those footprints contain valuable information of the bulk property of the (nearly) perfect liquid. By examing footprints of the nearly perfect liquid, we address a few important issues, including the ideal hydrodynamic li...

Over the past decade, an increasing number of authors have been examining the nexus of producer versus consumer responsibility, often dealing with the question of how to assign responsibility for internationally traded greenhouse gas emissions. Recently, a similar problem has appeared in drafting the standards for the Ecological Footprint: While the method traditionally assumes a full life-cycl...

The Tiger (Panthera tigris) population in India has undergone a sharp decline during the last few years. Of the number of factors attributed to this decline, habitat fragmentation has been the most worrisome. Wildlife corridors have long been a subject of discussion amongst wildlife biologists and conservationists with contrasting schools of thought arguing their merits and demerits. However, i...
