Environmental Indicator
Environmental indicators are simple measures that tell us what is happening in the environment. Since the environment is very complex, indicators provide a more practical and economical way to track the state of the environment than if we attempted to record every possible variable in the environment. For example, concentrations of ozone depleting substances (ODS) in the atmosphere, tracked over time, is a good indicator with respect to the environmental issue of stratospheric ozone depletion. Environmental indicators have been defined in different ways but common themes exist. “An environmental indicator is a numerical value that helps provide insight into the state of the environment or human health. Indicators are developed based on quantitative measurements or statistics of environmental condition that are tracked over time. Environmental indicators can be developed and used at a wide variety of geographic scales, from local to regional to national levels.” “A parameter ...

Economic Indicator
An economic indicator is a statistic about an economic activity. Economic indicators allow analysis of economic performance and predictions of future performance. One application of economic indicators is the study of business cycles. Economic indicators include various indices, earnings reports, and economic summaries: for example, the unemployment rate, quits rate (quit rate in American English), housing starts, consumer price index (a measure for inflation), Inverted yield curve, consumer leverage ratio, industrial production, bankruptcies, gross domestic product, broadband internet penetration, retail sales, price index, and money supply changes. The leading business cycle dating committee in the United States of America is the private National Bureau of Economic Research. The Bureau of Labor Statistics is the principal fact-finding agency for the U.S. government in the field of labor economics and statistics. Other producers of economic indicators includes the United Sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leigh Hunt
James Henry Leigh Hunt (19 October 178428 August 1859), best known as Leigh Hunt, was an English critic, essayist and poet. Hunt co-founded '' The Examiner'', a leading intellectual journal expounding radical principles. He was the centre of the Hampstead-based group that included William Hazlitt and Charles Lamb, known as the "Hunt circle". Hunt also introduced John Keats, Percy Bysshe Shelley, Robert Browning and Alfred Tennyson to the public. Hunt's presence at Shelley's funeral on the beach near Viareggio was immortalised in the painting by Louis Édouard Fournier. Hunt inspired aspects of the Harold Skimpole character in Charles Dickens' novel ''Bleak House''. Early life James Henry Leigh Hunt was born 19 October 1784, at Southgate, London, where his parents had settled after leaving the United States. His father, Isaac, a lawyer from Philadelphia, and his mother, Mary Shewell, a merchant's daughter and a devout Quaker, had been forced to come to Britain because ...

Indicator Of Compromise
Indicator of compromise (IoC) in computer forensics is an artifact observed on a network or in an operating system that, with high confidence, indicates a computer intrusion. Types of indication Typical IoCs are virus signatures and IP addresses, MD5 hashes of malware files, or URLs or domain names of botnet command and control servers. After IoCs have been identified via a process of incident response and computer forensics, they can be used for early detection of future attack attempts using intrusion detection systems and antivirus software. Automation There are initiatives to standardize the format of IoC descriptors for more efficient automated processing. Known indicators are usually exchanged within the industry, where the Traffic Light Protocol is being used.

Indicator Net
Constructed using light steel nets, indicator nets were often anchored at various depths to the sea bed around Allied naval bases during both world wars. They were intended to entangle U-boat traffic of the enemy, even though the submarines often managed to disentangle themselves and escape before being blown up by depth charges. Predominantly deployed by the Royal Navy as a means of discouraging enemy submarines from entering Allied waters, indicator nets were used extensively during World War I. Individual nets were sometimes as much as in length. Instead of being used as the sole anti-submarine measure, indicator nets were often mixed with extensive minefields and patrolling warships. Sometimes mines were attached directly to the nets, thus reducing submarine survival chances. After a submarine became entangled in the net, a marker buoy attached to the net drifted along the water's surface indicating an enemy below. The first example of indicator nets causing the destructio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indicator Function
In mathematics, an indicator function or a characteristic function of a subset of a set is a function that maps elements of the subset to one, and all other elements to zero. That is, if is a subset of some set , one has \mathbf_(x)=1 if x\in A, and \mathbf_(x)=0 otherwise, where \mathbf_A is a common notation for the indicator function. Other common notations are I_A, and \chi_A. The indicator function of is the Iverson bracket of the property of belonging to ; that is, :\mathbf_(x)= \in A For example, the Dirichlet function is the indicator function of the rational numbers as a subset of the real numbers. Definition The indicator function of a subset of a set is a function \mathbf_A \colon X \to \ defined as \mathbf_A(x) := \begin 1 ~&\text~ x \in A~, \\ 0 ~&\text~ x \notin A~. \end The Iverson bracket provides the equivalent notation, \in A/math> or to be used instead of \mathbf_(x)\,. The function \mathbf_A is sometimes denoted , , , or even just . Nota ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indicator Diagram
An indicator diagram is a chart used to measure the thermal, or cylinder, performance of reciprocating steam and internal combustion engines and compressors. An indicator chart records the pressure in the cylinder versus the volume swept by the piston, throughout the two or four strokes of the piston which constitute the engine, or compressor, cycle. The indicator diagram is used to calculate the work (thermodynamics), work done and the power produced in an engine cylinder or used in a compressor cylinder. The indicator diagram was developed by James Watt and his employee John Southern (engineer), John Southern to help understand how to improve the Energy conversion efficiency, efficiency of steam engines. In 1796, Southern developed the simple, but critical, technique to generate the diagram by fixing a board so as to move with the piston, thereby tracing the "volume" axis, while a pencil, attached to a pressure gauge, moved at right angles to the piston, tracing "pressure".

Indicator (statistics)
In statistics and research design, an indicator is an observed value of a variable, or in other words "a sign of a presence or absence of the concept being studied". Just like each color indicates in a traffic lights the change in the movement. For example, if a variable is religiosity, and a unit of analysis is an individual, then that one of potentially more numerous indicators of that individual's religiosity would be whether they attend religious services; others - how often, or whether they donate money to religious organizations. Numerous indicators can be aggregated into an index. The complexity of biological systems makes evaluating them a challenge. Bioindicators, such as indicator bacteria, are ecological indicators, sometimes requiring further consideration of environmental indicators. In public health study, one relies on health indicators. In a given locality, community indicators inform planners, while the design quality indicator can be the basis of building permi ...

Indicator (metadata)
In metadata, an indicator is a Boolean value that may contain only the values true or false. The definition of an Indicator must include the meaning of a true value and should also include the meaning if the value is false. If a data element may take another value to represent e.g. ''unknown'' or ''not applicable'', then a Code should be used instead of an Indicator, and the meanings of all possible values should be clearly defined. The suffix Indicator is used in ISO/IEC 11179 metadata registry standard as a representation term. Example of Use of Indicator in XML An example use of the Indicator suffix is if an XML document was required to contain the passing status of a Student in a statewide assessment. The data element would be: Standards that use the indicator representation term The following metadata registry standards use the term indicator * ebXML * NIEM * GJXDM See also * Metadata * ISO/IEC 11179 * Representation term * Code In communications and informatio ...
