    Figure ‎2.6 Numerical experiment N.B with fire at atrium at 250 Sec [9] Figure ‎2.7 Physical model P.M with fire at atrium at 250 Sec. [9] It was concluded that the height of the atrium and the fan locations have obvious effect on the efficient abstraction. Atrium with height more than 30 m with exhaust fans located towards the ends may require attention to control the smoke abstraction efficiently. Yi, Hou, Li and Feng & Chow [13] study the relation between the atrium aspect ratio

    aspect ratio of atrium under different heat release rate (HRR) of fire,32 simulations were carried out using a “field” model, FDS (Fire Dynamics Simulator, Version 3). The size of the atrium and HRR of steady fire are listed in Table (2-4). In all the simulations, the size of the fire room was set at 3 m × 3 m × 3 m, the fire was located at the center of the floor of the fire room, the height of atrium was 27 m. The vents in the fire floor were both 2 m × 1.5 m with sill at 1 m above the floor. The

    The upper zone is characterized by the presences of hot gases produced by the fire. While the lower zones is the entire space beneath the upper zone. Zone model considers the upper space/zone as the area for control volume in the sense that it receives both energy and mass from the fire as well as losing the energy to the surface through the process of radiation and conduction. While the lower zone is considered to retain the ambient

    Wireless sensor network From Wikipedia, the free encyclopedia A wireless sensor network (WSN) is a computer network consisting of spatially distributed autonomous devices using sensors to cooperatively monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants, at different locations.[1] The development of wireless sensor networks was originally motivated by military applications such as battlefield surveillance. However, wireless sensor networks

    repeated by many. David Vergun interviewed Maj. Mike Stinchfield, chief of the Training Innovation Facility, Army National Simulation Center, Army Combined Arms Center, Fort Leavenworth, Kansas for MilGaming Online. In this article, Vergun states, “Simulators are cost-effective in terms of fuel and maintenance, and they also allow trainers to simulate variables that are dangerous and costly to simulate in real life: weather conditions, difficult terrain and enemy attacks.” (Vergun, 2016). Simulations

    Abstract High-rise apartments are probably the fires posing most danger to life and property in residential areas. The spread of flame in high rise Buildings up the vertical walls has been studied computationally and experimentally all around the globe for decades now. Flames in the high-rise building fires can travel up the shafts provided for lifts, through spacing in the interior walls, up and down the stairwells and ductwork provided for air conditioning but one of the quickest ways the flames

    ventilation system, because if fire is initiated in atrium by any different causes at any level of atrium where there is amount of fuel to maintain steady heat release rate, there is probability that the fire will be maintained. Study fire development, smoke layer, temperature distribution and carbon monoxide concentration is complicated and unstable. Therefore, computational fluid dynamics is useful tool to analyze smoke management system. FDS (Fire Dynamic Simulator) is frequently used tool in such

    complex science concepts, such as dynamic molecular structures. (Klopfer, E., & Osterweil, S., 2009) The program also has a tool to allow teachers to track progress and grade assessments. Another simulation used for commonly for science is StarLogo: The Next Generation. This program is used heavily in math and science. The simulation allows students to create their own simulation and also alter it. For example, the program could be used to create a simulation of the dynamics between fish and plankton. (Klopfer

    main types of fire protection: active and passive. The differences between the two are that active fire protection requires outside help in the form of mechanical or electrical power for the device to work. A passive system works with no outside help at all. Fire containment is a passive protection method. There are three types of passive devices: limiting the rate of fire growth, fire containment and then emergency egress. Fire containment is accomplished by limiting a fully involved fire to the room

    Traffic Lab ITEC 201 In this lab we will examine the impact of traffic on major cities by running a few test simulations as well as examining data on the topic. Please answer the following questions in detail. 1. What are some major challenges you feel cities face when dealing with and handling large amounts of traffic? What could be some potential solutions that could minimize some traffic congestion? When dealing with handling large amounts of traffic, cities may experience a higher incidence
