LTE (telecommunication)
In telecommunications, long-term evolution (LTE) is a standard for wireless broadband communication for cellular mobile devices and data terminals. It is considered to be a "transitional" 4G technology, and is therefore also referred to as 3.95G as a step above 3G. LTE is based on the 2G GSM/ EDGE and 3G UMTS/ HSPA standards. It improves on those standards' capacity and speed by using a different radio interface and core network improvements. LTE is the upgrade path for carriers with both GSM/UMTS networks and CDMA2000 networks. LTE has been succeeded by LTE Advanced, which is officially defined as a "true" 4G technology and also named "LTE+". Terminology The standard is developed by the 3GPP (3rd Generation Partnership Project) and is specified in its Release 8 document series, with minor enhancements described in Release 9. LTE is also called 3.95G and has been marketed as 4G LTE and Advanced 4G; but the original version did not meet the technical criteria of a 4G wire ...

Compaq LTE
The LTE is a line of Notebook (laptop), notebook-sized laptops manufactured by Compaq, Compaq Computer Corporation, introduced in 1989 and discontinued in 1997. It was the first notebook computer sold by Compaq and the first commercially successful notebook that was IBM PC compatible, compatible with the IBM Personal Computer, IBM PC. Development of the LTE line began in 1986; the company conceived it as their first attempt at a truly lightweight portable computer, aiming to replace their Compaq Portable series, Portable and Compaq SLT, SLT lines. The first two models in the LTE line—the Compaq LTE (1st generation), LTE and Compaq LTE/286, LTE/286—competed with other notebook computers such as NEC's NEC UltraLite, UltraLite and Zenith Data Systems, Zenith's Zenith MinisPort, MinisPort. However, whereas the UltraLite and MinisPort failed to gain much uptake due to their novel but nonstandard data storage technologies, the LTE succeeded on account of its use of the conventional f ...

LTE Advanced
LTE Advanced, also named or recognized as LTE+, LTE-A or 4G+, is a 4G mobile Cellular network, cellular communication standard developed by 3GPP as a major enhancement of the LTE (telecommunication), Long Term Evolution (LTE) standard. Three technologies from the LTE-Advanced tool-kit carrier aggregation, 4x4 MIMO and 256QAM modulation in the downlink if used together and with sufficient aggregated bandwidth, can deliver maximum peak downlink speeds approaching, or even exceeding, 1 Gbit/s. This is significantly more than the peak 300 Mbit/s rate offered by the preceding LTE standard. Later developments have resulted in LTE Advanced Pro (or 4.9G) which increases bandwidth even further. The first ever LTE Advanced network was deployed in 2013 by SK Telecom in South Korea. In August 2019, the Global mobile Suppliers Association (GSA) reported that there were 304 commercially launched LTE-Advanced networks in 134 countries. Overall, 335 operators are investing in LTE-Adv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Letter To The Editor
A letter to the editor (LTE) is a Letter (message), letter sent to a publication about an issue of concern to the reader. Usually, such letters are intended for publication. In many publications, letters to the editor may be sent either through Mail, conventional mail or electronic mail. Letters to the editor are most frequently associated with newspapers and news magazines, however, they are sometimes published in other periodicals such as entertainment and technical magazines and #Academic, academic journals. Radio station, Radio and television station, television stations may also receive such letters, which are sometimes read on the air, particularly on news commentary broadcasts or on talk radio. In this presentation form the letter to the editor can also be described as viewer mail or listener mail, depending on the medium. Subject matter The subject matter of letters to the editor vary widely. However, the most common topics include: * Supporting or opposing a stance take ...

LTE International Airways
Lte International Airways S.A. (Lte Volar Airlines) was a Spanish charter airline based in Palma de Mallorca, Spain. It operated passenger charter services throughout Europe. Its main base was Son Sant Joan Airport, Palma de Mallorca with hubs at Tenerife South Airport, Gran Canaria Airport, Lanzarote Airport, Fuerteventura Airport and Josep Tarradellas Barcelona–El Prat Airport. History The airline was established on 29 April 1987 by Spanish businessmen and German LTU International. It started operations on 1 November 1987. From 1993 until May 2001, LTU was the sole owner having bought out the other original shareholders. On 24 May 2001, LTU sold the airline to a group of Spanish and Italian businessmen, including the Volare Group. As a result, LTE was rebranded Volar Airlines for two successive years 2003 and 2004. In 2005, the airline was renamed back to LTE International Airways. The airline was wholly owned by Gasarer. From July 2008, Lte operated flights betwee ...

Liquid Tension Experiment
Liquid Tension Experiment (LTE) is an American instrumental progressive metal supergroup founded by Mike Portnoy in 1997. The band initially released two albums, between 1998 and 1999. An extension of their second regular album, with the absence of John Petrucci was released in 2007 under the name "Liquid Trio Experiment". Active up until 1999, when Jordan Rudess formally joined Dream Theater, the band reunited in 2008 for a series of live shows. A live album with the absence of Jordan Rudess (mostly) was released in 2009 under the name "Liquid Trio Experiment 2", as were three live albums and two videos featuring the complete band. They regrouped once again in 2020 to record a third studio album featuring all band members, which was released on April 16, 2021. History Formation, studio albums and tours Liquid Tension Experiment was formed by Dream Theater drummer Mike Portnoy after Magna Carta gave him the green light for "whatever he wanted to do".

Local Thermodynamic Equilibrium
Thermodynamic equilibrium is a notion of thermodynamics with axiomatic status referring to an internal state of a single thermodynamic system, or a relation between several thermodynamic systems connected by more or less permeable or impermeable walls. In thermodynamic equilibrium, there are no net macroscopic flows of mass nor of energy within a system or between systems. In a system that is in its own state of internal thermodynamic equilibrium, not only is there an absence of macroscopic change, but there is an “absence of any ''tendency'' toward change on a macroscopic scale.” Systems in mutual thermodynamic equilibrium are simultaneously in mutual thermal, mechanical, chemical, and radiative equilibria. Systems can be in one kind of mutual equilibrium, while not in others. In thermodynamic equilibrium, all kinds of equilibrium hold at once and indefinitely, unless disturbed by a thermodynamic operation. In a macroscopic equilibrium, perfectly or almost perfectly balanc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London Transport Executive
The London Transport Executive was the organisation responsible for public transport in Greater London, England between 1948 and 1962. In common with all London transport authorities from 1933 to 2000, the public name and operational brand of the organisation was London Transport (brand), London Transport. Formation On 1 January 1948, pursuant to the Transport Act 1947, the London Passenger Transport Board (LPTB) was nationalised and renamed the London Transport Executive (LTE), becoming a subsidiary organisation of the British Transport Commission, which was formed on the same day. Another subsidiary of the commission was the Railway Executive (which traded as British Railways), which meant that London Transport and the main-line railways were under the same management for the first and last time in their respective histories. Projects A great deal of the early work of the LTE was spent repairing and replacing stock and stations damaged during World War II. LTE also overs ...

Leukotriene
Leukotrienes are a family of eicosanoid inflammation, inflammatory mediators produced in leukocytes by the redox, oxidation of arachidonic acid (AA) and the essential fatty acid eicosapentaenoic acid (EPA) by the enzyme arachidonate 5-lipoxygenase. Leukotrienes use lipid signaling to convey information to either the cell producing them (autocrine signaling) or neighboring cells (paracrine signaling) in order to regulate immune responses. The production of leukotrienes is usually accompanied by the production of histamine and prostaglandins, which also act as inflammatory mediators. One of their roles (specifically, Leukotriene D4, leukotriene D4) is to trigger contractions in the smooth muscles lining the bronchioles; their overproduction is a major cause of inflammation in asthma and allergic rhinitis. Leukotriene antagonists are used to treat these disorders by inhibiting the production or activity of leukotrienes. History and name The name ''leukotriene'', introduced by ...

Loss Of Tail-rotor Effectiveness
Loss of tail-rotor effectiveness (LTE)Rotorcraft Flying Handbook Section 11-12, Federal Aviation Administration, Skyhorse Publishing (July 2007) occurs when the tail rotor of a helicopter is exposed to wind forces that prevent it from carrying out its function—that of cancelling the torque of the engine and transmission. Any low-airspeed high-power environment provides an opportunity for it to occur. Causes Environmental factors which can lead to LTE include higher operating-density altitudes or temperatures, and high winds. A high gross weight can also create an LTE-conducive situation. Causative wind-directions may include: # Main rotor disk interference - Main-rotor disk vortices are pushed into the tail rotor by wind. This can occur with wind coming from 10 o'clock on North American (counter-clockwise) rotors and from 2 o'clock on clockwise rotors. The wind pushes the dirty air and vortices generated from the main-rotor into the tail-rotor, preventing the tail rotor fr ...

Lifting-the-exponent Lemma
In elementary number theory, the lifting-the-exponent lemma (or, Mihai's lemma) provides several formulas for computing the p-adic valuation \nu_p of special forms of integers. The lemma is named as such because it describes the steps necessary to "lift" the exponent of p in such expressions. It is related to Hensel's lemma. Background Although this lemma has been rediscovered many times and is now part of mathematical "folklore", its ideas appear as early as 1878 in the work of Édouard Lucas,É. Lucas, "Théorie des Fonctions Numériques Simplement Périodiques. ontinued, ''American Journal of Mathematics'', vol. 1 (1878), pp. 197–240. https://www.jstor.org/stable/2369308 who was then a professor at Lycée Charlemagne. Lucas described related divisibility results (with a minor error in the case p = 2). However, the modern and systematic formulation of the lemma, especially in the context of olympiad mathematics, was first published by Romanian mathematician Mihai Manea in 200 ...
