Tracking System
A tracking system or locating system is used for Surveillance, tracking persons or objects that do not stay in a fixed location, and supplying a time-ordered sequence of positions (track). Applications A myriad of tracking systems exist. Some are 'lag time' indicators, that is, the data is collected after an item has passed a point for example, a bar code or choke point or gate. Others are 'real-time' or 'near real-time' like Global Positioning Systems (GPS) depending on how often the data is refreshed. There are bar-code systems which require items to be scanned and other which have Automatic identification and data capture, automatic identification (RFID auto-id). For the most part, the tracking worlds are composed of discrete hardware and software systems for different applications. That is, bar-code systems are separate from Electronic Product Code (EPC) systems and GPS systems are separate from active real time locating systems or Real-time locating, RTLS. For example ...

FEMA - 37846 - Evacuees Are Entered Into A Computer Tracking System In Texas
The Federal Emergency Management Agency (FEMA) is an agency of the United States Department of Homeland Security (DHS), initially created under President Jimmy Carter by Presidential Reorganization Plan No. 3 of 1978 and implemented by two Executive order (United States), Executive Orders on April 1, 1979. The agency's primary purpose is to coordinate the response to a disaster that has occurred in the United States and that overwhelms the resources of local and U.S. state, state authorities. The governor of the state in which the disaster occurs must declare a state of emergency and formally request from the President of the United States, president that FEMA and the Federal government of the United States, federal government respond to the disaster. The only exception to the state's gubernatorial declaration requirement occurs when an emergency or disaster takes place on federal property or to a federal asset—for example, the 1995 Oklahoma City bombing, bombing of the Alfred ...

Unique Identifier
A unique identifier (UID) is an identifier that is guaranteed to be unique among all identifiers used for those objects and for a specific purpose. The concept was formalized early in the development of computer science and information systems. In general, it was associated with an atomic data type. In relational databases, certain attributes of an entity that serve as unique identifiers are called '' primary keys''. In mathematics, set theory uses the concept of '' element indices'' as unique identifiers. Classification There are some main types of unique identifiers, each corresponding to a different generation strategy: # serial numbers, assigned incrementally or sequentially, by a central authority or accepted reference. # random numbers, selected from a number space much larger than the maximum (or expected) number of objects to be identified. Although not really unique, some identifiers of this type may be appropriate for identifying objects in many practical applica ...

Line-of-sight Propagation
Line-of-sight propagation is a characteristic of electromagnetic radiation or acoustic wave propagation which means waves can only travel in a direct visual path from the source to the receiver without obstacles. Electromagnetic transmission includes light emissions traveling in a straight line. The rays or waves may be diffracted, refracted, reflected, or absorbed by the atmosphere and obstructions with material and generally cannot travel over the horizon or behind obstacles. In contrast to line-of-sight propagation, at low frequency (below approximately 3 MHz) due to diffraction, radio waves can travel as ground waves, which follow the contour of the Earth. This enables AM radio stations to transmit beyond the horizon. Additionally, frequencies in the shortwave bands between approximately 1 and 30 MHz, can be refracted back to Earth by the ionosphere, called skywave or "skip" propagation, thus giving radio transmissions in this range a potentially global reach ...

Telematics
Telematics is an interdisciplinary field encompassing telecommunications, vehicular technologies (road transport, road safety, etc.), electrical engineering (sensors, instrumentation, wireless communications, etc.), and computer science (multimedia, Internet, etc.). Telematics can involve any of the following: * The technology of sending, receiving, and storing information using telecommunication devices to control remote objects * The integrated use of telecommunications and informatics for application in vehicles and to control vehicles on the move * Global navigation satellite system technology integrated with computers and mobile communications technology in automotive navigation systems * (Most narrowly) The use of such systems within road vehicles (also called vehicle telematics) History Telematics is a translation of the French word ''télématique,'' which was first coined by Simon Nora and Alain Minc in a 1978 report to the French government on the computerizati ...

A-GPS
Assisted GNSS (A-GNSS) is a GNSS augmentation system that often significantly improves the startup performance—i.e., time-to-first-fix (TTFF)—of a global navigation satellite system (GNSS). A-GNSS works by providing the necessary data to the device via a radio network instead of the slow satellite link, essentially "warming up" the receiver for a fix. When applied to GPS, it is known as assisted GPS or augmented GPS (abbreviated generally as A-GPS and less commonly as aGPS). Other local names include A-GANSS for Galileo and A-Beidou for BeiDou. A-GPS is extensively used with GPS-capable cellular phones, as its development was accelerated by the U.S. FCC's 911 requirement to make cell phone location data available to emergency call dispatchers. Background Every GPS device requires orbital data about the satellites to calculate its position. The data rate of the satellite signal is only 50 bit/s, so downloading orbital information like ephemerides and the almanac directly fro ...

Location-based Services
Location-based service (LBS) is a general term denoting software services which use geographic data and information to provide services or information to users. LBS can be used in a variety of contexts, such as health, indoor object search, entertainment, work, personal life, etc. Commonly used examples of location-based services include navigation software, social networking services, location-based advertising, and tracking systems. LBS can also include mobile commerce when taking the form of coupons or advertising directed at customers based on their current location. LBS also includes personalized weather services and even location-based games. LBS is critical to many businesses as well as government organizations to drive real insight from data tied to a specific location where activities take place. The spatial patterns that location-related data and services can provide is one of its most powerful and useful aspects where location is a common denominator in all of these ...

Mass Surveillance
Mass surveillance is the intricate surveillance of an entire or a substantial fraction of a population in order to monitor that group of citizens. The surveillance is often carried out by Local government, local and federal governments or intelligence agency, governmental organizations, but it may also be carried out by corporations (either on behalf of governments or at their own initiative). Depending on each nation's laws and Judiciary, judicial systems, the legality of and the permission required to engage in mass surveillance varies. It is the single most indicative distinguishing trait of Totalitarianism, totalitarian regimes. It is often distinguished from targeted surveillance. Mass surveillance has often been cited by agencies like the National Security Agency (NSA) as necessary to fight terrorism, prevent crime and social unrest, protect national security, and control the population. At the same time, mass surveillance has equally often been criticized for violating pri ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Public Security
Public security or public safety is the prevention of and protection from events that could endanger the safety and security of the public from significant danger, injury, or property damage. It is often conducted by a state government to ensure the protection of citizens, persons in their territory, organizations, and institutions against threats to their well-being, survival, and prosperity. The public safety issues that a municipality, county, regional, or federal jurisdiction may handle include crimes (ranging from misdemeanors to felonies), structure fires, conflagrations, medical emergencies, mass-casualty incidents, disasters, terrorism, and other concerns. Public safety organizations are organizations that conduct public safety. They generally consist of emergency services and first responders such as law enforcement, fire services, emergency medical services, security forces, and military forces. They are often operated by a government, though some private p ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Welfare Spending
Welfare spending is a type of government support intended to ensure that members of a society can meet basic human needs such as food and shelter. Social security may either be synonymous with welfare, or refer specifically to social insurance programs which provide support only to those who have previously contributed (e.g. pensions), as opposed to ''social assistance'' programs which provide support on the basis of need alone (e.g. most disability benefits). The International Labour Organization defines social security as covering support for those in old age, support for the maintenance of children, medical treatment, parental and sick leave, unemployment and disability benefits, and support for sufferers of occupational injury. More broadly, welfare may also encompass efforts to provide a basic level of well-being through subsidized ''social services'' such as healthcare, education, infrastructure, vocational training, and public housing.''The New Fontana Diction ...

Citizen
Citizenship is a membership and allegiance to a sovereign state. Though citizenship is often conflated with nationality in today's English-speaking world, international law does not usually use the term ''citizenship'' to refer to nationality; these two notions are conceptually different dimensions of collective membership. Generally citizenships have no expiration and allow persons to work, reside and vote in the polity, as well as identify with the polity, possibly acquiring a passport. Though through discriminatory laws, like disfranchisement and outright apartheid, citizens have been made second-class citizens. Historically, populations of states were mostly subjects, while citizenship was a particular status which originated in the rights of urban populations, like the rights of the male public of cities and republics, particularly ancient city-states, giving rise to a civitas and the social class of the burgher or bourgeoisie. Since then states have expan ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Public Administration
Public administration, or public policy and administration refers to "the management of public programs", or the "translation of politics into the reality that citizens see every day",Kettl, Donald and James Fessler. 2009. ''The Politics of the Administrative Process''. Washington D.C.: CQ Press and also to the academic discipline which studies how public policy is created and implemented. In an academic context, public administration has been described as the study of government decision-making; the analysis of policies and the various inputs that have produced them; and the inputs necessary to produce alternative policies. It is also a subfield of political science where studies of policy processes and the structures, functions, and behavior of public institutions and their relationships with broader society take place. The study and application of public administration is founded on the principle that the proper functioning of an organization or institution relies on effectiv ...
