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...

This paper describes a system used in acoustic event detection task of the CLEAR2007 evaluation. The objective of the task is to detect acoustic events (door slam, steps, paper wrapping etc.) using acoustic data from a multiple microphone set up in the meeting room environment. A system based on hidden Markov models and multichannel audio data was implemented. Mel-Frequency Cepstral Coe cients ...

OBJECTIVE To assess the prevalence and type of fluorosis among children from randomly selected villages of Chhattisgarh, and its relationship with fluoride levels in drinking water. METHODS A community based door-to-door survey was conducted in the sampled villages of seven districts of Chhattisgarh state during the year 2013-14. The field case definitions were used for labelling types of flu...

Recently the American College of Cardiology and the American Heart Association instituted DTB of 90 minutes or less as a class I recommendation. Since 2006 the percentage of patient meeting this metric has substantially increased, although research has demonstrated discrepancies in whether or not this objective is associated with better patient outcome. Here, we reviewed seven studies in effort...

PURPOSE This study was undertaken to explore the effects of the jaws and the MLC openings on the neutron dose equivalent (DE) at the maze door and neutron flux at the patient plane. METHODS The neutron dose equivalent was measured at the maze entrance door of a 15 MV therapy linear accelerator room. All measurements were performed using various field sizes up to 40 cm × 40 cm. Activation dete...

objectives: this study aimed to assess the effect of storage time and temperature on dimensional stability of impressions made with cavex outline zinc oxide impression paste. materials and methods: a round stainless steel mold with five grooves (three horizontal and two vertical) was used in this in-vitro experimental study. cavex outline impression paste was prepared according to the manufactu...

Doors are important elements of building façades in scanned point clouds. Accurate door detection is a critical step reconstruction and indoor navigation. However, recent methods may often obtain incomplete information can only detect doors with single state (open or closed). To improve this, recognition method proposed based on corner straight-line fitting. Firstly, plane segmentation local fe...
