Alberta Emergency Alert
Alberta Emergency Alert (AEA) is a public warning system in Alberta that warns the public on impending or occurring emergencies affecting an area. The system was implemented in October 2011, replacing the former Alberta Emergency Public Warning System. Alerts are disseminated through various media outlets including television and radio, internet, social media mobile apps, and cell broadcast. Alerts are set into two stages; an "Information Alert", in which the public is advised to be prepared for potentially life-threatening emergencies. Information Alerts do not interrupt TV and radio broadcast. A "Critical Alert" in which potentially life-threatening danger is imminent or present such as a tornado touchdown. TV and radio stations in Alberta must transmit "Critical" messages from Alberta Emergency Alert. The system also broadcasts alerts in the event of an AMBER alert. Unlike the previous system (where the alerts were read on-air by a recorded voice), alerts are read using a te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emergency Population Warning
An emergency population warning is a method whereby local, regional, or national authorities can contact members of the public en masse to warn them of an impending emergency. These warnings may be necessary for a number of reasons, including: * weather emergencies such as tornadoes, hurricanes, and ice storms; * geological disasters such as earthquakes, landslides, volcanic eruptions, and tsunamis; * industrial disasters such as the release of toxic gas or contamination of river water; * radiological disasters such as a nuclear plant disaster; * medical emergencies such as an outbreak of a fast-moving infectious disease; * warfare or acts of terrorism. Many local areas use emergency population warnings to advise of prison escapes, abducted children, emergency telephone number outages, and other events. Requirements In order to develop an effective emergency warning system, certain things are required: * an agreement as to what constitutes an emergency in the area served by ...

Emergency Notification System
An emergency notification system is a method of facilitating the one-way dissemination or broadcast of messages to one or many groups of people, alerting them to a pending or existing emergency. The Emergency Notification System (ENS) was created by Dialogic Communication Corporation (DCC) in the early 1980s. DCC, including its patent portfolio, was purchased by Motorola Solutions as part of their 2018 acquisition of Airbus DS Communications. Notification vs. communication Emergency notification systems constitute a (one-way communication) subset of the types of systems described by the broader term emergency communication systems which includes systems that provide one-way and two-way communications, between emergency communications staff, first responders, and impacted individuals. Mass automated dialing services such as Reverse 9-1-1, and the common town siren systems that are used to alert for tornadoes, tsunami, air-raid, etc., are examples of emergency notification systems. ...

Emergency Public Warning System
The Emergency Public Warning System was a system used in the province of Alberta, Canada until October 2011, whereby local or provincial authorities could warn the public about impending or current emergencies affecting their area. The system was replaced by the Alberta Emergency Alert but is still in use by the provinces Ontario and British Columbia. The system was proposed by the provincial government after an F4 tornado ripped through Edmonton, Alberta on July 31, 1987, killing 27 people and causing millions of dollars in damage. The EPWS could be activated by local police, fire, and environmental agencies; by Environment Canada; and by other provincial and local authorities as required. It could be activated for any of the following reasons: *Severe weather *Flood *Wildfire * Hazardous material release *Terrorist threat *Water contamination *AMBER Alert *Other threats to life, property and safety. The EPWS was originally operated by the CKUA Radio Network The CKUA Rad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alberta
Alberta ( ) is one of the thirteen provinces and territories of Canada. It is part of Western Canada and is one of the three prairie provinces. Alberta is bordered by British Columbia to the west, Saskatchewan to the east, the Northwest Territories (NWT) to the north, and the U.S. state of Montana to the south. It is one of the only two landlocked provinces in Canada (Saskatchewan being the other). The eastern part of the province is occupied by the Great Plains, while the western part borders the Rocky Mountains. The province has a predominantly continental climate but experiences quick temperature changes due to air aridity. Seasonal temperature swings are less pronounced in western Alberta due to occasional Chinook winds. Alberta is the fourth largest province by area at , and the fourth most populous, being home to 4,262,635 people. Alberta's capital is Edmonton, while Calgary is its largest city. The two are Alberta's largest census metropolitan areas. More tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mobile App
A mobile application or app is a computer program or software application designed to run on a mobile device such as a phone, tablet, or watch. Mobile applications often stand in contrast to desktop applications which are designed to run on desktop computers, and web applications which run in mobile web browsers rather than directly on the mobile device. Apps were originally intended for productivity assistance such as email, calendar, and contact databases, but the public demand for apps caused rapid expansion into other areas such as mobile games, factory automation, GPS and location-based services, order-tracking, and ticket purchases, so that there are now millions of apps available. Many apps require Internet access. Apps are generally downloaded from app stores, which are a type of digital distribution platforms. The term "app", short for " application", has since become very popular; in 2010, it was listed as "Word of the Year" by the American Dialect Society. Apps a ...

Cell Broadcast
Cell Broadcast (CB) is a method of sending messages to multiple mobile telephone users in a defined area at the same time. It is defined by the ETSI’s GSM committee and 3GPP and is part of the 2G, 3G, 4G LTE (telecommunication) and 5G standards. It is also known as Short Message Service-Cell Broadcast (SMS-CB) or CB SMS. Unlike Short Message Service-Point to Point (SMS-PP), Cell Broadcast is a one-to-many geo-targeted and geo-fenced messaging service. History Cell Broadcast messaging was first demonstrated in Paris in 1997. Some mobile operators used Cell Broadcast for communicating the area code of the antenna cell to the mobile user (via channel 050), for nationwide or citywide alerting, weather reports, mass messaging, location-based news, etc. Cell broadcast has been widely deployed since 2008 by major Asian, US, Canadian, South American and European network operators. Not all operators have the Cell Broadcast messaging function activated in their network yet, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tornado
A tornado is a violently rotating column of air that is in contact with both the surface of the Earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. It is often referred to as a twister, whirlwind or cyclone, although the word cyclone is used in meteorology to name a weather system with a low-pressure area in the center around which, from an observer looking down toward the surface of the Earth, winds blow counterclockwise in the Northern Hemisphere and clockwise in the Southern. Tornadoes come in many shapes and sizes, and they are often visible in the form of a condensation funnel originating from the base of a cumulonimbus cloud, with a cloud of rotating debris and dust beneath it. Most tornadoes have wind speeds less than , are about across, and travel several kilometers (a few miles) before dissipating. The most extreme tornadoes can attain wind speeds of more than , are more than in diameter, and stay on the ground for more than 100 k ...

AMBER Alert
An Amber Alert (alternatively styled AMBER alert) or a child abduction emergency alert ( SAME code: CAE) is a message distributed by a child abduction alert system to ask the public for help in finding abducted children. The system originated in the United States. AMBER is a backronym standing for America's Missing: Broadcast Emergency Response. It was created in reference to Amber Rene Hagerman, a girl who was abducted and later found murdered in 1996. Alternative regional alert names were once used; in Georgia, "Levi's Call" (in memory of Levi Frady); in Hawaii, "Maile Amber Alert" (in memory of Maile Gilbert); in Arkansas, "Morgan Nick Amber Alert" (in memory of Morgan Nick); and in Utah, "Rachael Alert" (in memory of Rachael Runyan). In the United States, Amber alerts are distributed via commercial and public radio stations, Internet radio, satellite radio, television stations, text messages, and cable TV by the Emergency Alert System and NOAA Weather Radio (where they ...

Text-to-speech
Speech synthesis is the artificial production of human speech. A computer system used for this purpose is called a speech synthesizer, and can be implemented in software or hardware products. A text-to-speech (TTS) system converts normal language text into speech; other systems render symbolic linguistic representations like phonetic transcriptions into speech. The reverse process is speech recognition. Synthesized speech can be created by concatenating pieces of recorded speech that are stored in a database. Systems differ in the size of the stored speech units; a system that stores phones or diphones provides the largest output range, but may lack clarity. For specific usage domains, the storage of entire words or sentences allows for high-quality output. Alternatively, a synthesizer can incorporate a model of the vocal tract and other human voice characteristics to create a completely "synthetic" voice output. The quality of a speech synthesizer is judged by its similarity to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CRTC
The Canadian Radio-television and Telecommunications Commission (CRTC; french: Conseil de la radiodiffusion et des télécommunications canadiennes, links=) is a public organization in Canada with mandate as a regulatory agency for broadcasting and telecommunications.
