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 ...

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...

Risk assessment is a standard tool in health care systems which is used to improve patient safety. Failure mode and effects analysis (FMEA) as a powerful risk assessment tool for safety and reliability widely applied by industries such as aerospace, nuclear, automotive, chemical, mechanical, medical technologies, and electronics. FMEA is popular technique, but it has some substantial deficienci...

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...

O scar the Cat awakens from his nap, opening a single eye to survey his kingdom. From atop the desk in the doctor's charting area, the cat peers down the two wings of the nursing home's advanced dementia unit. All quiet on the western and eastern fronts. Slowly, he rises and extravagantly stretches his 2-year-old frame, first backward and then forward. He sits up and considers his next move. In...

The shielding calculations for high energy (>10 MV) linear accelerators must include the photoneutron production within the head of the accelerator. Procedures have been described to calculate the treatment room door shielding based on the neutron source strength (Q value) for a specific accelerator and energy combination. Unfortunately, there is currently little data in the literature stating ...
