Danish Meteorological Institute
The Danish Meteorological Institute (DMI; ) is the official Danish meteorological institute, administrated by the Ministry of Climate, Energy and Utilities. It makes weather forecasts and observations for Denmark, Greenland, and the Faroe Islands. History The Danish Meteorological Institute (DMI) was founded in 1872, primarily through the efforts of Ludwig A. Colding. DMI integrates the expertise of three predecessor organizations: the former Meteorological Institute, the Meteorological Service for Civil Aviation, and the Meteorological Service for Defence. * The Meteorological Institute was established in 1872 under the Ministry of the Navy. * The Meteorological Service for Civil Aviation began operations in 1926 as part of the Civil Aviation Administration. * The Meteorological Service for Defence was created in 1953. The current DMI was formed in 1990 through the merger of these three institutions. It operates under the Ministry of Transport and employs approximately 38 ...

Copenhagen
Copenhagen ( ) is the capital and most populous city of Denmark, with a population of 1.4 million in the Urban area of Copenhagen, urban area. The city is situated on the islands of Zealand and Amager, separated from Malmö, Sweden, by the Øresund strait. The Øresund Bridge connects the two cities by rail and road. Originally a Vikings, Viking fishing village established in the 10th century in the vicinity of what is now Gammel Strand, Copenhagen became the capital of Denmark in the early 15th century. During the 16th century, the city served as the ''de facto'' capital of the Kalmar Union and the seat of the Union's monarchy, which governed most of the modern-day Nordic countries, Nordic region as part of a Danish confederation with Sweden and Norway. The city flourished as the cultural and economic centre of Scandinavia during the Renaissance. By the 17th century, it had become a regional centre of power, serving as the heart of the Danish government and Military history ...

Vector Processor
In computing, a vector processor or array processor is a central processing unit (CPU) that implements an instruction set where its instructions are designed to operate efficiently and effectively on large one-dimensional arrays of data called ''vectors''. This is in contrast to scalar processors, whose instructions operate on single data items only, and in contrast to some of those same scalar processors having additional single instruction, multiple data (SIMD) or SIMD within a register (SWAR) Arithmetic Units. Vector processors can greatly improve performance on certain workloads, notably numerical simulation, compression and similar tasks. Vector processing techniques also operate in video-game console hardware and in graphics accelerators. Vector machines appeared in the early 1970s and dominated supercomputer design through the 1970s into the 1990s, notably the various Cray platforms. The rapid fall in the price-to-performance ratio of conventional microprocessor de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Weather Radar
A weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation (meteorology), precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.). Modern weather radars are mostly pulse-Doppler radars, capable of detecting the motion of rain droplets in addition to the intensity of the precipitation. Both types of data can be analyzed to determine the structure of storms and their potential to cause severe weather. During Radar in World War II, World War II, radar operators discovered that weather was causing echoes on their screens, masking potential enemy targets. Techniques were developed to filter them, but scientists began to study the phenomenon. Soon after the war, military surplus, surplus radars were used to detect precipitation. Since then, weather radar has evolved and is used by national weather services, research departments in universities, and in television stations' weather d ...

C Band (IEEE)
The C band is a designation by the Institute of Electrical and Electronics Engineers (IEEE) for a portion of the electromagnetic spectrum The electromagnetic spectrum is the full range of electromagnetic radiation, organized by frequency or wavelength. The spectrum is divided into separate bands, with different names for the electromagnetic waves within each band. From low to high ... in the microwave range of frequencies ranging from 4.0 to 8.0 Hertz, gigahertz (GHz). However, the U.S. Federal Communications Commission C band proceeding and auction, designated 3.7–4.2 GHz as C band. The C band is used for many satellite communications transmissions, some Cordless telephone, cordless telephones, as well as some Surveillance, radar and Weather radar, weather radar systems. The C band contains the 5.725 - 5.875 GHz ISM band allowing unlicensed use by low power devices, such as garage door openers, wireless doorbells, and baby monitors. A very large us ...

FARICE-1
FARICE-1 is a submarine communications cable connecting Iceland, the Faroe Islands and Scotland. The cable has been in use since January 2004 and is 100% owned by Iceland. The cable had an initial design capacity of 720 Gbit/s and is a two fibre pair design. The length of the cable is 1205 km for the direct route between Iceland and Scotland. The cable structure and repeaters were made by Pirelli and the terminal equipment was supplied by TYCO. In the year 2013 the terminal equipment was upgraded by Ciena (100 Gbit/s technology) bringing the total capacity of the submarine cable to 11 Tbit/s. The cable has service access points in Reykjavik and Keflavik Airport as well as in London Telehouse East. The company Farice ehf sells services over the FARICE-1 cable. FARICE-2 was never built. DANICE is the complementary submarine cable. The landing points are: * 1. Seyðisfjörður, Iceland, backhauled to Reykjavík and KEF Airport * 3. Funningsfjørður, Faroe I ...

Gigabit Per Second
In telecommunications, data transfer rate is the average number of bits (bitrate), characters or symbols ( baudrate), or data blocks per unit time passing through a communication link in a data-transmission system. Common data rate units are multiples of bits per second (bit/s) and bytes per second (B/s). For example, the data rates of modern residential high-speed Internet connections are commonly expressed in megabits per second (Mbit/s). Standards for unit symbols and prefixes Unit symbol The ISQ symbols for the bit and byte are ''bit'' and ''B'', respectively. In the context of data-rate units, one byte consists of 8 bits, and is synonymous with the unit octet. The abbreviation bps is often used to mean bit/s, so that when a ''1 Mbps'' connection is advertised, it usually means that the maximum achievable bandwidth is 1 Mbit/s (one million bits per second), which is 0.125 MB/s ( megabyte per second), or about 0.1192 MiB/s ( mebibyte per second).

TeraFLOPS
Floating point operations per second (FLOPS, flops or flop/s) is a measure of computer performance in computing, useful in fields of scientific computations that require floating-point calculations. For such cases, it is a more accurate measure than measuring instructions per second. Floating-point arithmetic Floating-point arithmetic is needed for very large or very small real numbers, or computations that require a large dynamic range. Floating-point representation is similar to scientific notation, except computers use base two (with rare exceptions), rather than base ten. The encoding scheme stores the sign, the exponent (in base two for Cray and VAX, base two or ten for IEEE floating point formats, and base 16 for IBM Floating Point Architecture) and the significand (number after the radix point). While several similar formats are in use, the most common is ANSI/IEEE Std. 754-1985. This standard defines the format for 32-bit numbers called ''single precision'', a ...
