Design Example: Flow Through a Fire Extinguisher

206
A fire extinguisher that uses pressurized water relies on fluid dynamics principles to generate a high-velocity stream capable of suppressing flames. The water is stored at a much higher pressure inside the extinguisher than the surrounding atmosphere. This pressure difference forces the water to flow rapidly when the extinguisher is activated, and the behavior of the water as it exits the nozzle can be understood using fundamental equations of fluid dynamics.
The key to understanding how the...

Schemas

12.0K
A schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

Applications of GIS: Disaster Management and Emergency Response

168
Geographic Information System (GIS) technology is essential for risk identification, action prioritization, and resource optimization in critical situations like flooding and earthquakes. By integrating spatial and demographic data, GIS provides a comprehensive framework for emergency response.GIS integrates data layers, like rainfall intensity, topography, elevation profiles, and river levels, to model high-risk flood zones. These layers assess areas susceptible to flooding based on their...

Household Wiring And Electrical Safety01:13

Household Wiring And Electrical Safety

1.4K
Companies that supply power to most modern households use three conductors, typically called a three-wire line. While one is neutral, the other two are both at 120 V but with opposite polarity, giving a voltage of 240 V between them. With a three-wire line, high-power appliances that require 240 V, such as electric stoves and clothes dryers, are linked between the two hot lines. 120 V appliances can be connected between the neutral and either of the hot lines. The neutral side, which is always...

Design Example: Identifying the Locations of Monuments in the Field Using Global Positioning System Device

176
Surveyors use Global Positioning System (GPS) technology to measure the precise location and elevation of points on Earth. In a recent survey, GPS receivers were used to determine the coordinates and elevations of two park monuments. The process involved careful mission planning, data collection, and correction to ensure accuracy. The survey began with mission planning to identify optimal satellite visibility and minimize Position Dilution of Precision (PDOP). A geodetic control point...

Design Example: Resistive Touchscreen01:14

Design Example: Resistive Touchscreen

455
A device engineer plays a crucial role in designing user interfaces for mobile devices. One such interface is the resistive touchscreen, which fundamentally consists of two metallic layers: a flexible upper layer and a rigid lower layer, separated by a narrow gap. The high resistance between these two layers is a key characteristic of this design.
When a user touches the screen, the two layers make contact at a specific point known as the touchpoint. This contact reduces the resistance between...

  • Fire safety engineering
  • Human-computer interaction
  • Emergency response systems

Background:

  • Fire smoke significantly impairs visibility of emergency signage, compromising building evacuation.
  • Inadequate guidance during fires can lead civilians to hazardous, smoke-filled routes.
  • Existing systems lack effective solutions for smoke-obscured evacuation guidance.

Purpose of the Study:

  • To propose and evaluate a smartphone voice-guided evacuation system (SVGES) as an alternative guidance method during fires.
  • To determine the efficacy of SVGES in directing civilians to safe evacuation routes amidst fire-induced smoke.

  • Participants using the SVGES consistently selected the safest evacuation routes.
  • The study achieved a 100% successful evacuation rate among participants utilizing the SVGES.
  • SVGES proved effective in overcoming the navigational challenges posed by fire smoke.

Conclusions:

  • The smartphone voice-guided evacuation system (SVGES) is a viable and effective solution for fire emergency navigation.
  • SVGES enhances civilian safety by providing reliable guidance independent of visual cues obscured by smoke.
