Object Process Diagram
Object Process Methodology (OPM) is a conceptual modeling language and methodology for capturing knowledge and designing systems, specified as ISO/ PAS 19450. Based on a minimal universal ontology of stateful objects and processes that transform them, OPM can be used to formally specify the function, structure, and behavior of artificial and natural systems in a large variety of domains. OPM was conceived and developed by Dov Dori. The ideas underlying OPM were published for the first time in 1995. Since then, OPM has evolved and developed. In 2002, the first book on OPM was published, and on December 15, 2015, after six years of work by ISO TC184/SC5, ISO adopted OPM as ISO/PAS 19450. A second book on OPM was published in 2016. Since 2019, OPM has become a foundation for a Professional Certificate program in Model-Based Systems Engineering - MBSat EdX Lectures are availablas web videos on Youtube Overview Object Process Methodology (OPM) is a conceptual modeling lang ...

One Per Desk
The One Per Desk, or OPD, was an innovative hybrid personal computer/telecommunications terminal based on the hardware of the Sinclair QL. The One Per Desk was built by International Computers Limited (ICL) and launched in the UK in 1984. It was the result of a collaborative project between ICL, Sinclair Research and British Telecom begun in 1983, originally intended to incorporate Sinclair's flat-screen CRT technology. Rebadged versions of the OPD were sold in the United Kingdom as the Merlin Tonto and as the Computerphone by Telecom Australia and the New Zealand Post Office. The initial orders placed for the One Per Desk were worth £4.5 million (for 1500 units) from British Telecom and £8 million from Telecom Australia, with ICL focusing on telecommunications providers as the means to reach small- and medium-sized businesses. Hardware From the QL, the OPD borrowed the 68008 CPU, ZX8301/ 8302 ULAs, 128 KB of RAM and dual Microdrives (re-engineered by ICL fo ...

Oakland Police Department
The Oakland Police Department (OPD) is a law enforcement agency responsible for policing the city of Oakland, California, United States. As of May 2021, the department employed 709 sworn officers and 371 civilian employees. The department is divided into 5 geographical divisions policing Oakland's 78 square miles and population of 420,000. The OPD receives 550,000 annual calls for service, and responds to over 250,000 law enforcement incidents. History The Oakland Police Department was formed in 1853 by Oakland founder and first Mayor Horace W. Carpentier. Oakland had been incorporated as a town by the state legislature in 1852, and with its rapid expansion, Carpentier felt the need to organize a city government with a police force to provide regular law enforcement. Heretofore, vigilante justice had been the norm. On October 15, 1853, the town council appointed John McCann as the first town marshal, assisted by two deputies and operating out of a small waterfront building which ...

Organizational Process Definition
The Capability Maturity Model Integration (CMMI) defines a Process Area as, "A cluster of related practices in an area that, when implemented collectively, satisfies a set of goals considered important for making improvement in that area." Both CMMI for Development v1.3 and CMMI for Acquisition v1.3 identify 22 process areas, whereas CMMI for Services v1.3 identifies 24 process areas. Many of the process areas are the same in these three models. Process Area Organization In CMMI models, the process areas are organized in alphabetical order according to their acronym. However, process areas can be grouped according to maturity levels or process area categories. Maturity Levels: CMMI for Development There are Five maturity levels. However, maturity level ratings are awarded for levels 2 through 5. The process areas below and their maturity levels are listed for the CMMI for Development model: Maturity Level 2 - Managed * CM - Configuration Management * MA - Measurement and Ana ...

Optical Path Difference
In optics, optical path length (OPL, denoted ''Λ'' in equations), also known as optical length or optical distance, is the product of the geometric length of the optical path followed by light and the refractive index of homogeneous medium through which a light ray propagates; for inhomogeneous optical media, the product above is generalized as a path integral as part of the ray tracing procedure. A difference in OPL between two paths is often called the optical path difference (OPD). OPL and OPD are important because they determine the phase of the light and governs interference and diffraction of light as it propagates. Formulation In a medium of constant refractive index, ''n'', the OPL for a path of geometrical length ''s'' is just :\mathrm = n s .\, If the refractive index varies along the path, the OPL is given by a line integral :\mathrm = \int_C n \mathrm d s,\quad where ''n'' is the local refractive index as a function of distance along the path ''C''.

O-Phenylenediamine
''o''-Phenylenediamine (OPD) is an organic compound with the formula C6H4(NH2)2. This aromatic diamine is an important precursor to many heterocyclic compounds. It is isomeric with ''m''-phenylenediamine and ''p''-phenylenediamine. Preparation Commonly, 2-nitrochlorobenzene is treated with ammonia and the resulting 2-nitroaniline is then hydrogenated: :ClC6H4NO2 + 2 NH3 → H2NC6H4NO2 + NH4Cl :H2NC6H4NO2 + 3 H2 → H2NC6H4NH2 + 2 H2O In the laboratory, the reduction of the nitroaniline is effected with zinc powder in ethanol, followed by purification of the diamine as the hydrochloride salt. This compound darkens in air; impurities may be removed by treating a hot aqueous solution with sodium dithionite (reducing agent) and activated carbon, then allowing the product to cool and crystallize. Reactions and uses ''o''-Phenylenediamine condenses with ketones and aldehydes to give rise to a variety of useful products. Reactions with carboxylic acids and their derivatives affor ...

Propane
Propane () is a three-carbon alkane with the molecular formula . It is a gas at standard temperature and pressure, but compressible to a transportable liquid. A by-product of natural gas processing and petroleum refining, it is commonly used as a fuel in domestic and industrial applications and in low-emissions public transportation. Discovered in 1857 by the French chemist Marcellin Berthelot, it became commercially available in the US by 1911. Propane is one of a group of liquefied petroleum gases (LP gases). The others include butane, propylene, butadiene, butylene, isobutylene, and mixtures thereof. Propane has lower volumetric energy density, but higher gravimetric energy density and burns more cleanly than gasoline and coal. Propane gas has become a popular choice for barbecues and portable stoves because its low −42 °C boiling point makes it vaporise inside pressurised liquid containers (2 phases). Propane powers buses, forklifts, taxis, outboard boat motors, and ic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Outpatient Department
An outpatient department or outpatient clinic is the part of a hospital designed for the treatment of outpatients, people with health problems who visit the hospital for diagnosis or treatment, but do not at this time require a bed or to be admitted for overnight care. Modern outpatient departments offer a wide range of treatment services, diagnostic tests and minor surgical procedures. Department The outpatient department of a hospital provides diagnosis and care for patients that do not need to stay overnight. The departments are also sometimes called outpatient clinics, but are distinct from clinics independent of hospitals, almost all of which are designed mostly or exclusively for outpatient care and may also be called outpatient clinics. The outpatient department is an important part of the overall running of the hospital. It is normally integrated with the in-patient services and staffed by consultant physicians and surgeons who also attend inpatients in the wards. Many pat ...
