What is CASE MIX INDEX? What does CASE MIX INDEX mean? CASE MIX INDEX meaning - CASE MIX INDEX definition - CASE MIX INDEX explanation.
Case mix index (CMI) is a relative value assigned to a diagnosis-related group of patients in a medical care environment. The CMI value is used in determining the allocation of resources to care for and/or treat the patients in the group.
Patients are classified into groups having the same condition (based on main and secondary diagnosis, procedures, age), complexity (comorbidity) and needs. These groups are known as Diagnosis Related Groups (DRG), or Resource Use Groups (RUG).
Each DRG has a relative average value assigned to it that indicates the amount of resources required to treat patients in the group, as compared to all the other diagnosis-related groups within the system. The relative average value assigned to each group is its CMI.
The CMI of a hospital reflects the diversity, clinical complexity and the needs for resources in the population of all the patients in the hospital.
What is PRACTICAL ENGLISH USAGE? What does PRACTICAL ENGLISH USAGE mean? PRACTICAL ENGLISH USAGE meaning - PRACTICAL ENGLISH USAGE definition - PRACTICAL ENGLISH USAGE explanation.
Practical English Usage is a standard reference book aimed at foreign learners of English and their teachers written by Michael Swan.
Published by Oxford University Press, it has sold over 2 million copies since the first edition was published in 1980. A new, and greatly extended second edition was published in 1995. A third edition was released in 2005, and a fourth in 2016.
It features basic descriptions of English grammar and usage as well as highlighting various words which are often problematic for non-native speakers. Although the model is basically British English, it explains some of the stylistic differences between British and American usage.
The third edition also takes into account some of the most recent changes within British English, particularly the commonisation of various American English forms (such as the use of like as a conjunction - e.g. like I do).

What is N-ISDN? What does N-ISDN mean? N-ISDN meaning - N-ISDN definition - N-ISDN explanation.
N-ISDN (Narrowband Integrated Switch digital Network) was an attempt to replace the analog telephone system with a digital one. Unfortunately, the standardization process was too long and regarding to the technology progress in this area, once the standard was finally agreed, it was obsolete.
It generally uses 64 kbit/s channel as the basic unit of switching. It has a circuit switching orientation. Its major contribution was Frame Relay. It describes telecommunication that carries voice information in a narrow band of frequencies.
N-ISDN basic rate is too low so for home as for business today. N-ISDN may be partly saved, but by an unexpected application: Internet access. Various companies now sell ISDN adapters that combine the 2B + D channels into a single 144 kbit/s digital channel. Many Internet providers also support these adapters. So the people can access the Internet over a 144 kbit/s digital link, instead of a 28.8 kbit/s analog modem link and for affordable price that may be a niche for N-ISDN for the next few years.
N-ISDN is also known as Normal-ISDN.

What is FREQUENCY AVERAGING? What does FREQUENCY AVERAGING mean? FREQUENCY AVERAGING meaning - FREQUENCY AVERAGING definition - FREQUENCY AVERAGING explanation.
In telecommunication, the term frequency averaging has the following meanings:
1. The process by which the relative phases of precision clocks are compared for the purpose of defining a single time standard.
2. A process in which network synchronization is achieved by use, at all nodes, of oscillators that adjust their frequencies to the average frequency of the digital bit streams received from connected nodes.
In frequency averaging, all oscillators are assigned equal weight in determining the ultimate network frequency.

What is DIGITAL SIGNAL 0? What does DIGITAL SIGNAL 0 mean? DIGITAL SIGNAL 0 meaning - DIGITAL SIGNAL 0 definition - DIGITAL SIGNAL 0 explanation.
Digital Signal 0 (DS0) is a basic digital signaling rate of 64 kilobits per second (kbit/s), corresponding to the capacity of one analog voice-frequency-equivalent communication channel. The DS0 rate, and its equivalents E0 in the E-carrier system and T0 in the T-carrier system, form the basis for the digital multiplex transmission hierarchy in telecommunications systems used in North America, Europe, Japan, and the rest of the world, for both the early plesiochronous systems such as T-carrier and for modern synchronous systems such as SDH/SONET.
The DS0 rate was introduced to carry a single digitized voice call. For a typical phone call, the audio sound is digitized at an 8 kHz sample rate, or 8000 samples per second, using 8-bit pulse-code modulation for each of the samples. This results in a data rate of 64 kbit/s.
Because of its fundamental role in carrying a single phone call, the DS0 rate forms the basis for the digital multiplex transmission hierarchy in telecommunications systems used in North America. To limit the number of wires required between two involved in exchanging voice calls, a system was built in which multiple DS0s are multiplexed together on higher capacity circuits. In this system, twenty-four (24) DS0s are multiplexed into a DS1 signal. Twenty-eight (28) DS1s are multiplexed into a DS3. When carried over copper wire, this is the well-known T-carrier system, with T1 and T3 corresponding to DS1 and DS3, respectively.
Besides its use for voice communications, the DS0 rate may support twenty 2.4 kbit/s channels, ten 4.8 kbit/s channels, five 9.67 kbit/s channels, one 56 kbit/s channel, or one 64 kbit/s clear channel.

What is INSERTION GAIN? What does INSERTION GAIN mean? INSERTION GAIN meaning - INSERTION GAIN definition - INSERTION GAIN explanation.
In telecommunication, insertion gain is the gain resulting from the insertion of a device in a transmission line, expressed as the ratio of the signal power delivered to that part of the line following the device to the signal power delivered to that same part before insertion. If the resulting number is less than unity, an "insertion loss" is indicated.
Insertion gain is usually expressed in dB.

What is BBC MUSIC? What does BBC MUSIC mean? BBC MUSIC meaning - BBC MUSIC definition - BBC MUSIC explanation.
BBC Music is an umbrella title used by the BBC to collect together its music output. Officially it is a part of the BBC's Radio operational division and is directly responsible to Helen Boaden (director of Radio); however, its remit also includes music used in television and online services. It was established in its current form in 2014; however, the BBC had already been using the BBC Music brand to refer to its online music content and some live events beforehand, including a now defunct record label. The current director of music is Bob Shennan, who is also the controller of BBC Radio 2, BBC Radio 6 Music and the BBC Asian Network.
BBC Music had its official launch at 20:00 on 7 October 2014, with a simulcast of a specially-commissioned cover of the Beach Boys' 1966 song "God Only Knows". Produced by Ethan Johns, it featured a supergroup of singers such as Chris Martin (of Coldplay), Stevie Wonder, Kylie Minogue, Dave Grohl (of Foo Fighters), Elton John, Pharrell Williams and One Direction, accompanied by the BBC Concert Orchestra.
BBC Music is responsible for the music played across the BBC. It has direct editorial control of the music content of the BBC's six national music radio stations Radio 1, 1Xtra, Radio 2, Radio 3, 6 Music and the BBC Asian Network, as well as organising live music events for each of the stations. These include Radio 1's Big Weekend, Live in Hyde Park and In Concert for Radio 2, the BBC Proms (including the various "Proms in the Park" events), and the BBC 6 Music festival.
Many of the BBC televisual music programmes and documentaries are now co-produced with BBC Music, with a BBC Music ident often being played between the regular channel ident and the start of the programme. It will also coordinate the BBC's coverage of other live music events such as the Glastonbury Festival, T in the Park, the Reading and Leeds Festivals and Celtic Connections amongst others.

What is OPEN SYSTEMS ARCHITECTURE? What does OPEN SYSTEMS ARCHITECTURE mean? OPEN SYSTEMS ARCHITECTURE meaning - OPEN SYSTEMS ARCHITECTURE definition - OPEN SYSTEMS ARCHITECTURE explanation.
Open systems architecture, in telecommunication, is a standard that describes the layered hierarchical structure, configuration, or model of a communications or distributed data processing system that:
1. Enables system description, design, development, installation, operation, improvement, and maintenance to be performed at a given layer or layers in the hierarchical structure.
2. Allows each layer to provide a set of accessible functions that can be controlled and used by the functions in the layer above it.
3. Enables each layer to be implemented without affecting the implementation of other layers.
4. Allows the alteration of system performance by the modification of one or more layers without altering the existing equipment, procedures, and protocols at the remaining layers.
Open systems architecture may be implemented using the OSI Model as a guide while designing the system to meet performance requirements.

What is ELECTRON-REFRACTIVE EFFECT? What does ELECTRON-REFRACTIVE EFFECT mean? ELECTRON-REFRACTIVE EFFECT meaning - ELECTRON-REFRACTIVE EFFECT definition - ELECTRON-REFRACTIVE EFFECT explanation.
The electron-refractive effect or Electron Induced Permittivity Modification (EIPM) is an electro-optic effect observed in some crystals and amorphous materials, such as chalcogenide glasses and oxides, where the permittivity reduces or increases when the material is illuminated by high energy electrons, typically from an transmission electron microscope or scanning electron microscope. The effect is non-linear and reversible.
The effect was observed by N. Normand and O. Normand., who observed that the permittivity, of chalcogenide glass increased by as much as 5% when irradiated with an electron gun in the 30keV range; they also noticed that the change was accompanied by a change in the thickness of the film. Recently San-Roman-Alerigi, Anjum and Ooi, demonstrated that the permittivity of chalcogenide thin films could also be reduced by as much as 50% when the sample was illuminated by 300keV electrons; moreover they also demonstrated that the electron induced permittivity modification was reversible.
The change in permittivity occurs because of the disruption in the atomic structure of the materials. That is, the changes are due to the breaking of bonds and re-bonding within the atomic structure of the amorphous or crystalline structures. This modification in turn modifies the carrier traps within the band structure, reducing them, and hence ensuing the decrement in the permittivity This contrasts with the photorefractive effect where the change is induced by the alteration in the electron distribution due to the photon-absorption.
