Rapid Refresh (weather Prediction)
The Rapid Refresh (RR or RAP) is a numerical weather prediction (NWP) model. The model is designed to provide short-range hourly weather forecasts for North America. The Rapid Refresh was officially made operational on 1 May 2012, replacing the Rapid Update Cycle (RUC). The model also serves as the boundary conditions for the higher-resolution High Resolution Rapid Refresh (HRRR) model, that uses a grid spacing on a domain covering the continental United States. The Rapid Refresh is run at the NOAA National Centers for Environmental Prediction (NCEP). It is based on the framework of the Weather Research and Forecasting model (WRF); the Global Forecast System (GFS) provides the boundary parameters. The grid points are spaced every , with 50 vertical intervals extending up to the 10-hectopascal (10 mb) level of the atmosphere. The model runs once each hour, with new information being integrated every 15 minutes. Forecasts are given hourly out to 18 hours and 48 hours every 6th ru ...

Rr (debugging)
In computing, rr is a debugging tool for Linux designed to record and replay program execution. During the replay phase, rr provides an enhanced gdb debugging experience that supports reverse execution. rr was originally developed by Mozilla to debug Mozilla Firefox on commodity hardware and software. rr is now widely used outside Mozilla and capable of debugging software such as Google Chrome, QEMU, and LibreOffice. rr is free software Free software, libre software, libreware sometimes known as freedom-respecting software is computer software distributed open-source license, under terms that allow users to run the software for any purpose as well as to study, change, distribut .... Design During the recording phase, rr records all inputs to a Linux process group from the kernel, as well as nondeterministic CPU effects (such as rdtsc). These inputs are logged to disk and become the "trace". Once the trace is recorded, it can be replayed as many times as desired and all ...

Route Reflector
Border Gateway Protocol (BGP) is a standardized exterior gateway protocol designed to exchange routing and reachability information among autonomous systems (AS) on the Internet. BGP is classified as a path-vector routing protocol, and it makes routing decisions based on paths, network policies, or rule-sets configured by a network administrator. BGP used for routing within an autonomous system is called Interior Border Gateway Protocol (iBGP). In contrast, the Internet application of the protocol is called Exterior Border Gateway Protocol (EBGP). History The genesis of BGP was in 1989 when Kirk Lougheed, Len Bosack and Yakov Rekhter were sharing a meal at an IETF conference. They famously sketched the outline of their new routing protocol on the back of some napkins, hence often referenced to as the “Two Napkin Protocol”. It was first described in 1989 in RFC 1105, and has been in use on the Internet since 1994. IPv6 BGP was first defined in in 1994, and it was ...

Round-robin Scheduling
Round-robin (RR) is one of the algorithms employed by process and network schedulers in computing. Guowang Miao, Jens Zander, Ki Won Sung, and Ben Slimane, Fundamentals of Mobile Data Networks, Cambridge University Press, , 2016. As the term is generally used, time slices (also known as time quanta) are assigned to each process in equal portions and in circular order, handling all processes without priority (also known as cyclic executive). Round-robin scheduling is simple, easy to implement, and starvation-free. Round-robin scheduling can be applied to other scheduling problems, such as data packet scheduling in computer networks. It is an operating system concept. The name of the algorithm comes from the round-robin principle known from other fields, where each person takes an equal share of something in turn. Process scheduling To schedule processes fairly, a round-robin scheduler generally employs time-sharing, giving each job a time slot or ''quantum'' (its allowa ...

Resource Record
The Domain Name System (DNS) is a hierarchical and distributed name service that provides a naming system for computers, services, and other resources on the Internet or other Internet Protocol (IP) networks. It associates various information with ''domain names'' (identification strings) assigned to each of the associated entities. Most prominently, it translates readily memorized domain names to the numerical IP addresses needed for locating and identifying computer services and devices with the underlying network protocols. The Domain Name System has been an essential component of the functionality of the Internet since 1985. The Domain Name System delegates the responsibility of assigning domain names and mapping those names to Internet resources by designating authoritative name servers for each domain. Network administrators may delegate authority over subdomains of their allocated name space to other name servers. This mechanism provides distributed and fault-toleran ...

Roundup Ready
Roundup Ready is the Bayer (formerly Monsanto) trademark for its patented line of genetically modified crop seeds that are resistant to its glyphosate-based herbicide, Roundup (herbicide), Roundup. History In 1996, genetically modified ''Roundup Ready'' soybeans resistant to Roundup became commercially available, followed by ''Roundup Ready'' maize, corn in 1998. Current ''Roundup Ready'' crops include soy, corn (maize), canola, sugar beets, cotton, and alfalfa, with wheat still under development. Additional information on ''Roundup Ready'' crops is available on the GM Crops List. As of 2005, 87% of U.S. soybean fields were planted with glyphosate resistant varieties. While the use of Roundup Ready crops has increased the usage of herbicides measured in pounds applied per acre,Charles BenbrookEvidence of the Magnitude and Consequences of the Roundup Ready Soybean Yield Drag from University-Based Varietal Trials in 1998 Ag BioTech InfoNet Technical Paper Number 1 it has also change ...

Respiratory Rate
The respiratory rate is the rate at which breathing occurs; it is set and controlled by the respiratory center of the brain. A person's respiratory rate is usually measured in breaths per minute. Measurement The respiratory rate in humans is measured by counting the number of breaths for one minute through counting how many times the chest rises. A fibre-optic breath rate sensor can be used for monitoring patients during a magnetic resonance imaging scan. Respiration rates may increase with fever, illness, or other medical conditions. Inaccuracies in respiratory measurement have been reported in the literature. One study compared respiratory rate counted using a 90-second count period, to a full minute, and found significant differences in the rates.. Another study found that rapid respiratory rates in babies, counted using a stethoscope, were 60–80% higher than those counted from beside the cot without the aid of the stethoscope. Similar results are seen with animals when t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Risk Ratio
The relative risk (RR) or risk ratio is the ratio of the probability of an outcome in an exposed group to the probability of an outcome in an unexposed group. Together with risk difference and odds ratio, relative risk measures the association between the exposure and the outcome. Statistical use and meaning Relative risk is used in the statistical analysis of the data of Ecological study, ecological, Cohort study, cohort, medical and intervention studies, to estimate the strength of the association between exposures (treatments or risk factors) and outcomes. Mathematically, it is the incidence rate of the outcome in the exposed group, I_e, divided by the rate of the unexposed group, I_u. As such, it is used to compare the risk of an adverse outcome when receiving a medical treatment versus no treatment (or placebo), or for environmental risk factors. For example, in a study examining the effect of the drug apixaban on the occurrence of thromboembolism, 8.8% of placebo-treated pat ...

RR Interval
Heart rate is the frequency of the heartbeat measured by the number of contractions of the heart per minute (''beats per minute'', or bpm). The heart rate varies according to the body's physical needs, including the need to absorb oxygen and excrete carbon dioxide. It is also modulated by numerous factors, including (but not limited to) genetics, physical fitness, stress or psychological status, diet, drugs, hormonal status, environment, and disease/illness, as well as the interaction between these factors. It is usually equal or close to the pulse rate measured at any peripheral point. The American Heart Association states the normal resting adult human heart rate is 60–100 bpm. An ultra-trained athlete would have a resting heart rate of 37–38 bpm. ''Tachycardia'' is a high heart rate, defined as above 100 bpm at rest. ''Bradycardia'' is a low heart rate, defined as below 60 bpm at rest. When a human sleeps, a heartbeat with rates around 40–50 bpm is common and consider ...

Scipione Riva-Rocci
Scipione Riva Rocci (7 August 1863 in Almese, Piedmont – 15 March 1937 in Rapallo, Liguria) was an Italian internist, pathologist and pediatrician. He is best known for the invention of an easy-to-use cuff-based version of the mercury sphygmomanometer for the measurement of blood pressure. Biography Riva Rocci was born on 7 August in Almese in 1863. He graduated in medicine and surgery in 1888 from the University of Turin. From 1888 to 1898 he acted as assistant lecturer at the propaedeutic medical clinic in Turin under the guidance of Carlo Forlanini and assisted him in the application of "iatrogenic pneumothorax" for treatment of pulmonary tuberculosis. In 1894 he graduated in pathology and in 1907 in pediatrics. In 1898, he followed Forlanini to the University of Pavia where he continued to contribute to the development of Forlanini's method by showing that the technique did not have a major adverse effect on lung function. From 1900 until 1928 was chief clinician ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
