Category 4 Cable
Category 4 cable (Cat 4) is a cable that consists of eight copper wires arranged in four unshielded twisted pairs (UTP) supporting signals up to 20 MHz. It is used in telephone networks which can transmit voice and data up to 16 Mbit/s. For a brief period it was used for some Token Ring, 10BASE-T, and 100BASE-T4 networks, but was quickly superseded by Category 5 cable. It is no longer common or used in new installations and is not recognized by the current version of the ANSI/TIA-568 ANSI/TIA-568 is a technical standard for commercial building cabling for telecommunications products and services. The title of the standard is ''Commercial Building Telecommunications Cabling Standard'' and is published by the Telecommunication ... data cabling standards.

Classification Of Non-silicate Minerals
This list gives an overview of the classification of non-silicate minerals and includes mostly International Mineralogical Association (IMA) recognized minerals and its groupings. This list complements the List of minerals recognized by the International Mineralogical Association series of articles and List of minerals. Rocks, ores, mineral mixtures, not IMA approved minerals, not named minerals are mostly excluded. Mostly major groups only, or groupings used by ''New Dana Classification'' and ''Mindat''. Classification of minerals Introduction The grouping of the New Dana Classification and of the mindat.org is similar only, and so this classification is an overview only. Consistency is missing too on the group name endings (group, subgroup, series) between New Dana Classification and mindat.org. Category, class and supergroup name endings are used as layout tools in the list as well. ;Abbreviations: * "*" – Mineral not IMA-approved. * "?" – IMA discredited mineral name ...

IUCN Protected Area Categories
IUCN protected area categories, or IUCN protected area management categories, are categories used to classify protected areas in a system developed by the International Union for Conservation of Nature (IUCN). The enlisting of such areas is part of a strategy being used toward the conservation of the world's natural environment and biodiversity. The IUCN has developed the protected area management categories system to define, record and classify the wide variety of specific aims and concerns when categorising protected areas and their objectives. This categorisation method is recognised on a global scale by national governments and international bodies such as the United Nations and the Convention on Biological Diversity. Categories Category Ia – strict nature reserve A strict nature reserve (IUCN Category Ia) is an area which is protected from all but light human use in order to protect its biodiversity and also possibly its geological/geomorphical features.

Armed Services Vocational Aptitude Battery
The Armed Services Vocational Aptitude Battery (ASVAB) is a multiple choice test, administered by the United States Military Entrance Processing Command, used to determine qualification for enlistment in the United States Armed Forces. It is often offered to U.S. high school students when they are in the 10th, 11th and 12th grade, though anyone eligible for enlistment may take it. History The ASVAB was first introduced in 1968 and was adopted by all branches of the military in 1976. It underwent a major revision in 2002. In 2004, the test's percentile rank scoring system was renormalized, to ensure that a score of 50% really did represent doing better than exactly 50% of the test takers. Categories Format The ASVAB contains nine sections and takes three hours to complete. The duration of each section varies between 7 and 39 minutes, the longest being for Arithmetic Reasoning. The test is typically administered in a computerized format at Military Entrance Processing Sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vintage Car
A vintage car is, in the most general sense, an old automobile, and in the narrower senses of car enthusiasts and collectors, it is a car from the period of 1919 to 1930. Such enthusiasts have categorization schemes for ages of cars that enforce distinctions between antique cars, vintage cars, classic cars, and so on. The classification criteria vary, but consensus within any country is often maintained by major car clubs, for example the Vintage Sports-Car Club (VSCC) in the UK. History The vintage era in the automotive world was a time of transition. The car started off in 1919 as still something of a rarity, and ended up, in 1930, well on the way towards ubiquity. In fact, automobile production at the end of this period was not matched again until the 1950s. In the intervening years, most industrialized countries built nationwide road systems with the result that, towards the end of the period, the ability to negotiate unpaved roads was no longer a prime consideratio ...

Measurement Category
Measurement category is a method of classification by the International Electrotechnical Commission (IEC)http://assets.fluke.com/Appnotes/2042049_w.pdf of live electric circuits used in measurement and testing of installations and equipment, usually in the relation within a building (residential or industrial). The categories take into account the total continuous energy available at the given point of circuit, and the occurrence of impulse voltages. The energy can be limited by circuit breakers or fuses, and the impulse voltages by the nominal level of voltage. Measurement categories Measuring circuits are subjected to working voltages and transient stresses from the circuit to which they are connected during measurement or test. When the measuring circuit is used to measure mains, the transient stresses can be estimated by the location within the installation at which the measurement is performed. When the measuring circuit is used to measure any other electrical signal, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Categories Of New Testament Manuscripts
New Testament manuscripts in Greek are categorized into five groups, according to a scheme introduced in 1981 by Kurt and Barbara Aland in ''The Text of the New Testament''. The categories are based on how each manuscript relates to the various text-types. Generally speaking, earlier Alexandrian manuscripts are category I, while later Byzantine manuscripts are category V. Aland's method involved considering 1000 passages where the Byzantine text differs from non-Byzantine text. The Alands did not select their 1000 readings from all of the NT books; for example, none were drawn from Matthew and Luke. Description of categories The Alands' categories do not simply correspond to the text-types; all they do is demonstrate the 'Byzantine-ness' of a particular text; that is, how much it is similar to the Byzantine text-type, from least (Category I) to most similar (Category V). Category V can be equated with the Byzantine text-type, but the other categories are not necessarily re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Category Four Stadium
UEFA stadium categories are categories for football stadiums laid out in UEFA's Stadium Infrastructure Regulations. Using these regulations, stadiums are rated as category one, two, three, or four (renamed from elite) in ascending ranking order. These categories replaced the previous method of ranking stadiums on one to five star scale in 2006. A stadium must be rated as category four in order to host games in the playoffs of the qualifying stage for the UEFA Champions League, or any game in the main competition. Category four is also required to host any game in the main competition of the UEFA Europa League, UEFA Europa Conference League, UEFA Nations League or the UEFA European Championship final tournament. UEFA does not publish lists of stadiums fulfilling the criteria for any of the categories defined in the UEFA Stadium Infrastructure Regulations. General If a retractable roof is present, its use will be directed by consultation between the UEFA delegate and the main assig ...

List Of Regional Snowfall Index Category 4 Winter Storms
The Regional Snowfall Index (RSI) is a system used by NOAA to assess the societal impacts of winter storms in the United States. The scale is a replacement for the Northeast Snowfall Impact Scale (NESIS) system, which was used for winter storms just in the Northeastern United States; Regional Snowfall Index assesses winter storm impacts in the six easternmost regions of the United States instead of just the Northeast. Since its initiation, the NCDC has assigned RSI values to nearly 600 winter storms since 1900. Storms are ranked from Category 0 "Nuisance" to Category 5 "Extreme" on the scale. A Category 4 winter storm on the RSI scale is classified as "Crippling". The impact of the storms is assessed in six different regions of the United States: the Northeast, Northern Rockies and Plains, Ohio Valley, South, Southeast, and Upper Midwest. A Category 4 "Crippling" ranking is indicated by a numerical score between 10 and 18 on the scale. Out of the nearly 600 historical winter stor ...

List Of Northeast Snowfall Impact Scale Winter Storms
The Northeast Snowfall Impact Scale (NESIS) is a scale used to categorize winter storms in the Northeast United States. The scale was developed by meteorologists Paul Kocin and Louis Uccellini, and ranks snowstorms from Category 1 ("notable") to Category 5 ("extreme"). Only two historical blizzards, the 1993 Storm of the Century and the North American blizzard of 1996 are rated in the 5 "extreme" category. The scale differs from the Saffir–Simpson Hurricane Scale and Fujita Scale, which are used to classify tropical cyclones and tornadoes, respectively, in that it takes into account the number of people affected by the storm. The scale, as devised, is intended chiefly to assess past storms rather than assist in forecasts.Kocin and Uccellini, pp. 269–270 List There are two available values for NESIS. The original values that Paul Kocin and Louis Uccellini computed for storms in their original 2004 work "A Snowfall Impact Scale Derived From Northeast Storm Snowfall Distr ...
