Privately Held Company
A privately held company (or simply a private company) is a company whose shares and related rights or obligations are not offered for public subscription or publicly negotiated in the respective listed markets, but rather the company's stock is offered, owned, traded, exchanged privately, or Over-the-counter (finance), over-the-counter. In the case of a closed corporation, there are a relatively small number of shareholders or company members. Related terms are closely-held corporation, unquoted company, and unlisted company. Though less visible than their public company, publicly traded counterparts, private companies have major importance in the world's economy. 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 2005, using a substantially smaller pool size (22.7%) for comparison, the 339 companies on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infant Crying
Infant crying is the crying 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. Increased pressures a ...

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 * Cohe ...

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 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. Acoustics Acoustics is the interdisciplinary science that deals with the study of mechanical waves in gasses, liquids, and solids including vibration, sound, ultrasound, and infrasound. A scientist who works in the field of acoustics is an ''acoustician'', while someone working in the field of acoustical e ...

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) are voluntary partnerships between Local government in England, local authorities and businesses, set up in 2011 by the Department for Business, Innovation and Skills to help determine local econom ...

Bark (sound)
A bark is a sound most commonly produced from dogs. Other animals that make this noise include, but are not limited to, wolves, coyotes, foxes, seals and barking owls. Woof is the most common onomatopoeia in the English language for this sound. "Bark" is also a verb that describes the sound of many canids. University of Massachusetts Amherst researchers define a bark as a short vocalization. Definition While there is not a precise, consistent and functional acoustic definition for barking, researchers may classify barks according to several criteria. University of Massachusetts Amherst researchers define 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. In dogs Dog barking is distinct from wolf barking. Wolf barks represent only 2.4% of all wolf vocalizations and are described as ...

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''. 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 amount present and length of exposure. Smaller concentrations can be harmful over longer peri ...

Software
Software is a set of computer programs and associated documentation and data. This is in contrast to hardware, from which the system is built and which actually performs the work. At the lowest programming level, executable code consists of machine language instructions supported by an individual processor—typically a central processing unit (CPU) or a graphics processing unit (GPU). Machine language consists of groups of binary values signifying processor instructions that change the state of the computer from its preceding state. For example, an instruction may change the value stored in a particular storage location in the computer—an effect that is not directly observable to the user. An instruction may also invoke one of many input or output operations, for example displaying some text on a computer screen; causing state changes which should be visible to the user. The processor executes the instructions in the order they are provided, unless it is instructed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smoke Alarm
A smoke detector is a device that senses smoke, typically as an indicator of fire. Smoke detectors 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 (photoelectric) or by physical process (ionization). Detectors may use one or both sensing methods. Sensitive alarms 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 interlinked. 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 at all of the units. This happens even if household power h ...

Sound Recognition
Sound recognition is a technology, which is based on both traditional pattern recognition theories and audio signal analysis methods. Sound recognition technologies contain preliminary data processing, feature extraction and classification algorithms. Sound recognition can classify feature vectors. Feature vectors are created as a result of preliminary data processing and linear predictive coding. Sound recognition technologies are used for: * Music recognition * Speech recognition * Automatic alarm detection and identification for surveillance, monitoring systems, based on the acoustic environment * Assistance to disabled or elderly people affected in their hearing capabilities * Identifying species of animals such as fish and mammals, e.g. in acoustical oceanography Security In monitoring and security, an important contribution to alarm detection and alarm verification can be supplied, using sound recognition techniques. In particular, these methods could be helpful for intr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
