Privately Held Company
A privately held company (or simply a private company) is a company whose Stock, shares and related rights or obligations are not offered for public subscription or publicly negotiated in their respective listed markets. Instead, the Private equity, company's stock is offered, owned, traded or exchanged privately, also known as "over-the-counter (finance), over-the-counter". Related terms are unlisted organisation, unquoted company and private equity. Private companies are often less well-known than their public company, publicly traded counterparts but still have major importance in the world's economy. For example, in 2008, the 441 list of largest private non-governmental companies by revenue, largest private companies in the United States accounted for $1.8 trillion in revenues and employed 6.2 million people, according to ''Forbes''. In general, all companies that are not owned by the government are classified as private enterprises. This definition encompasses both publ ...

Carbon Monoxide Alarm
A carbon monoxide detector or CO detector is a device that detects the presence of the carbon monoxide (CO) gas to prevent carbon monoxide poisoning. In the late 1990s, Underwriters Laboratories changed the definition of a single station CO detector with a sound device to carbon monoxide (CO) alarm. This applies to all CO safety alarms that meet UL 2034 standard; however for passive indicators and system devices that meet UL 2075, UL refers to these as ''carbon monoxide detectors''. Most CO detectors use a sensor with a defined, limited lifespan, and will not work indefinitely. CO is a colorless, tasteless, and odorless gas produced by incomplete combustion of carbon-containing materials. It is often referred to as the "silent killer" because it is virtually undetectable by humans. In a study by Underwriters Laboratories, "Sixty percent of Americans could not identify any potential signs of a CO leak in the home". Elevated levels of CO can be dangerous to humans depending on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Metric
In software engineering and development, a software metric is a standard of measure of a degree to which a software system or process possesses some property. Even if a metric is not a measurement (metrics are functions, while measurements are the numbers obtained by the application of metrics), often the two terms are used as synonyms. Since quantitative measurements are essential in all sciences, there is a continuous effort by computer science practitioners and theoreticians to bring similar approaches to software development. The goal is obtaining objective, reproducible and quantifiable measurements, which may have numerous valuable applications in schedule and budget planning, cost estimation, quality assurance, testing, software debugging, software performance optimization, and optimal personnel task assignments. Common software measurements Common software measurements include: * ABC Software Metric * Balanced scorecard * Bugs per line of code * Code coverage * Coh ...

Sound Profile
In physics, sound is a vibration that propagates as an acoustic wave through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the ''reception'' of such waves and their ''perception'' by the brain. Only acoustic waves that have frequency, frequencies lying between about 20 Hz and 20 kHz, the audio frequency range, elicit an auditory percept in humans. In air at atmospheric pressure, these represent sound waves with wavelengths of to . Sound waves above 20 kHz are known as ultrasound and are not audible to humans. Sound waves below 20 Hz are known as infrasound. Different animal species have varying hearing ranges, allowing some to even hear ultrasounds. Definition Sound is defined as "(a) Oscillation in pressure, stress, particle displacement, particle velocity, etc., propagated in a medium with internal forces (e.g., elastic or viscous), or the superposition of such propagated oscillation. (b) Auditory sen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Of England Development Agency
The East of England Development Agency (EEDA) was a non-departmental public body and the regional development agency for the East of England region of England. It came into operation on 1 April 1999 and assumed the regional powers of English Partnerships, the Rural Development Commission and the SRB Challenge Fund. The total budget for 2005/06 was £140 million. From 2010 many of the powers that were vested in the East of England Regional Assembly were passed to the EEDA and to local authorities. The East of England Development Agency was abolished on 31 March 2012. Part of its remit was assumed by the relevant Local Enterprise Partnership In England, local enterprise partnerships (LEPs) were voluntary partnerships between local authorities and businesses, set up in 2011 by the Department for Business, Innovation and Skills to help determine local economic priorities and lead ec ...

Anglia Ruskin University
Anglia Ruskin University (ARU) is a public research university in the region of East Anglia, United Kingdom. Its origins date back to the Cambridge School of Art (CSA), founded by William John Beamont, a Fellow of Trinity College at the University of Cambridge, in 1858. The institution became a university in 1992 and was renamed after John Ruskin, the Oxford University professor and author, in 2005. Ruskin delivered the inaugural speech at the Cambridge School of Art in 1858. ARU is classified as one of the "post-1992 universities." The university's motto is in Latin: ''Excellentia per societatem'', which translates to ''Excellence through partnership'' in English. , Anglia Ruskin had 35,195 students. ARU has six campuses across the south-eastern portion of the United Kingdom in Cambridgeshire, Essex, and Greater London.

Bark (sound)
A bark is a sound most often produced by dogs. Other animals that make this noise include, but are not limited to, wolves, coyotes, foxes, seals, frogs and owls. "Bark" is also a verb that describes the sound of many canids. Definition There is no precise, consistent, and functional acoustic definition for barking, but researchers classify barks according to several criteria. Researchers at the University of Massachusetts Amherst and Hampshire College have defined a bark as a short, abrupt vocalization that is relatively loud and high-pitched, changes in frequency, and often repeats rapidly in succession.Lord, Kathryn., Feinstein, Mark., Coppinger, RaymondBarking and mobbing. ''Behavioural Processes''. 2009. Barking in dogs Dog barking is distinct from wolf barking. Wolf barks represent only 2.4% of all wolf vocalizations, in warning, defense, and protest. In contrast, dogs bark in many social situations, with acoustic communication in dogs being described as hypertr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infant Crying
Infant crying is the vocalizations of infants as a response to an internal or external stimulus. Infants cry as a form of basic instinctive communication. Essentially, newborns are transitioning from life in the womb to the external environment. Up to 27% of parents describe problems with infant crying in the first four months. Up to 38% identify a problem with their infant crying within the first year. Parents can be concerned about the amount of time that their infant cries, how the infant can be consoled, and disrupted sleeping patterns. Colic is used as a synonym for excessive crying of infants, even though colic may not be the cause of excessive crying. Physiology Crying may elicit the Valsalva reflex. This reflex negatively impacts sucking pressures and results in poor feeding. The cortisol levels will rise along with blood pressure. Increased blood pressure will have an effect on cerebral blood flow, cerebral blood flow velocity and intracranial pressure. Increa ...

Smoke Alarm
A smoke detector is a device that senses smoke, typically as an indicator of fire. Smoke detectors/alarms are usually housed in plastic enclosures, typically shaped like a disk about in diameter and thick, but shape and size vary. Smoke can be detected either optically (Photodiode, photoelectric) or by physical process (ionization). Detectors may use one or both sensing methods. Sensitive detectors can be used to detect and deter smoking in banned areas. Smoke detectors in large commercial and industrial buildings are usually connected to a central fire alarm system. Household smoke detectors, also known as ''smoke alarms'', generally issue an audible or visual alarm from the detector itself or several detectors if there are multiple devices interconnected. Household smoke detectors range from individual battery-powered units to several interlinked units with battery backup. With interlinked units, if any unit detects smoke, alarms will trigger all of the units. This happens eve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software
Software consists of computer programs that instruct the Execution (computing), execution of a computer. Software also includes design documents and specifications. The history of software is closely tied to the development of digital computers in the mid-20th century. Early programs were written in the machine language specific to the hardware. The introduction of high-level programming languages in 1958 allowed for more human-readable instructions, making software development easier and more portable across different computer architectures. Software in a programming language is run through a compiler or Interpreter (computing), interpreter to execution (computing), execute on the architecture's hardware. Over time, software has become complex, owing to developments in Computer network, networking, operating systems, and databases. Software can generally be categorized into two main types: # operating systems, which manage hardware resources and provide services for applicat ...
