Because only specific disks spin at a given time, what is not in use is literally a massive array of idle disks, which also means the system produces less heat than other large storage systems. The b. Index 4 is defined after index 8, and next generated index (value 19) is 9, since biggest index was 8. Large or imposing, as in quantity, scope, degree, intensity, or scale: "Local defense must be reinforced by the further deterrent of massive retaliatory power"(John Foster Dulles). Webopedia is an online dictionary and Internet search engine for information technology and computing definitions. In storage terminology a massive array of idle disks, or MAID as it is abbreviated, is a technology that uses a large group of hard disk drives, hundreds or even thousands, with only those drives that are needed actively spinning at any given time.

From Wikipedia, the free encyclopedia. There’s no set figure for what constitutes a Massive MIMO set-up, but the description tends to be applied to systems with tens or even hundreds of antennas. In massive MIMO, you have M degrees of freedom if you have M antennas at the base station. [ + of] A dazzling array of celebrities are … That means that, for example, five values of type int can be declared as an array without having to declare 5 … to the multiplexing gain and the array gain. More than 100 of the ET 302 families have filed suit against Boeing and are seeking an array of Boeing and FAA documents relating to the two crashes. Massive MIMO a technology where the number of terminals is much less than the number of base station (mobile station) antennas. It is the type of the math that you learned in senior high school or early years inthe university linear algebra. In the downlink, this means that you choose a precoding vector in 1 … If you take a look at the following expression, you would notice that it is made up of two big chunks. MAID (Massive Arrays of Inactive Disks・メイド)とは、コロラド大学のDirk Grunwaldによって提唱された、アクセス局在性に基づく階層化モデルをストレージシステムに適用した大規模ディスクアレイモデルのひとつである。 10. The Windows operating system (Windows OS) refers to a family of operating systems developed by Microsoft Corporation. MAID (Massive Arrays of Inactive Disks・メイド)とは、コロラド大学のDirk Grunwaldによって提唱された、アクセス局在性に基づく階層化モデルをストレージシステムに適用した大規模ディスクアレイモデルのひとつである。, 一般に、メモリにはアクセス局在性に基づく階層化モデルが存在し、それに基づいて実装されている。たとえば、CPUの内部レジスタからキャッシュメモリ・メインメモリ・補助記憶装置と徐々に低速・大容量の記憶装置を階層的に配置する事により、アクセスの集中度合いに応じた適切なメモリデバイスが割り当てられている。ディスクアレイシステムにも、やはりアクセスの集中が存在し、ディスクアレイ全体のうち80%のアクセスは、20%のハードディスクドライブに集中している事が統計的に明らかにされた。言い換えれば、高性能で常時スタンバイしているハードディスクドライブはディスクアレイ全体の20%だけでよく、残りのハードディスクドライブは低性能で常時モーターを回す必要すら無い。アクセス集中がおきる領域を担う高速なアクセスできる高階層のファイバーチャネルハードディスクドライブ等と、その下の階層にあるテープの様な非常に遅い媒体の間に、テープよりは若干高価で高速だが高階層の高性能ハードディスクドライブよりは安価なシリアルATAハードディスクドライブを大量に挿入する。これらの中階層にあるハードディスクドライブはアクセスが集中しないので通常モーターの回転を止めておく事によりシステム全体の寿命を延長する。そして安価なデバイスを使う事によりストレージシステム全体の性能を向上しながらもシステム全体のコストを削減するものである。, Enterprise Watch ディスクとテープのギャップを埋めるMAIDテクノロジ, https://ja.wikipedia.org/w/index.php?title=Massive_Arrays_of_Inactive_Disks&oldid=38955978.

[42] In a rich scattering environment, the full advantages of the massive MIMO system can be exploited using simple beamforming strategies such as maximum ratio transmission (MRT), [43] maximum ratio-combining (MRC) [44] or zero forcing (ZF). vb ( tr) 11. to dress in rich attire; adorn. Massive parallel sequencing or massively parallel sequencing is any of several high-throughput approaches to DNA sequencing using the concept of massively parallel processing; it is also called next-generation sequencing ( NGS) or second-generation sequencing. Hotmail was one of the first public webmail services that could be accessed from any web browser. Multidimensional Arrays. An array's type is written as type[], where type is the data type of the contained elements; the brackets are special symbols indicating that this variable holds an array. The size of the array is not part of its type (which is why the brackets are empty). The preceding program declares an array (named anArray) with the following line of code: Like declarations for variables of other types, an array declaration has two components: the array's type and the array's name. The Nationwide Transmutation Circle (国土錬成陣, Kokudo Renseijin), as it is most often referred to, is a gigantic Transmutation Circle being dug in the form of an interconnecting underground tunnel that travels all around the nation of Amestris. STBC (Space Time Block Coding) and SM … Vangie Beal is a freelance business and technology writer covering Internet technologies and online business since the late '90s. In storage terminology a massive array of idle disks, or MAID as it is abbreviated, is a technology that uses a large group of hard disk drives, hundreds or even thousands, with only those drives that are needed actively spinning at any given time. Massive MIMO is the back-bone for 5G network where 100 or more antenna elements are to be used for various benefits. With a massive MIMO antenna and complex signal processing, cell towers can take advantage of various propagation modes to send more data with better reliability. This improves performance but does not deliver fault tolerance, meaning all data is lost if one drive fails. In particular, with a simple power control scheme, Massive MIMO can o er uniformly good service for all users. This example creates a 1-based array. Converts c to its lowercase equivalent if c is an uppercase letter and has a lowercase equivalent. A Copan array can contain hundreds of terabytes of disks which share supply, controller, and cabinet. What is “Massive MIMO” Massive MIMO is the extension of traditional MIMO technology to antenna arrays having a large number (>>8) of controllable antennas Transmission signals from the antennas are adaptable by thegain or The Copan array treats drives in the array similar to a tape library (VTL) where only what is needed is actually powered. The term MIMO stands for Multiple Input Multiple Output. TECHNOLOGYADVICE DOES NOT INCLUDE ALL COMPANIES OR ALL TYPES OF PRODUCTS AVAILABLE IN THE MARKETPLACE.

If no such conversion is possible, the value returned is c unchanged. 1. countable noun [with singular or plural verb, usually singular] An array of different things or people is a large number or wide range of them. Instead, when iterating over collections I tend to use the map operator when it’s … Multidimensional arrays in MATLAB are an extension of the normal two-dimensional matrix. Generally to generate a multidimensional array, we first create a two-dimensional array and extend it. The word “massive” refer to the number of antennas and not the physical size. But it is difficult to introduce massive-elements antennas (100 or more elements) that are required for In case of low / mid frequency region without using massive antenna array (as in (A) / (B)), a single transmission would cover a lot of UEs simultaneously. Level 0 (striped disk array without fault tolerance): Level 0 provides data striping but no redundancy. (Computer Science) computing a regular data structure in which individual elements may be located by reference to one or more integer index variables, the number of such indices being the number of dimensions in the array. Antonyms for massive. There are two techniques by which complex data symbols are transmitted using multiple antennas viz. However, when the radiation become beam-shaped as (C), it is very difficult In order to achieve this, each array uses multiple antennas . It refers to multiple antennas used for transmission and reception of electro-magnetic waves. Array( [0] => 1 [1] => 1 [2] => 1 [3] => 13 [4] => 1 [8] => 1 [9] => 19) Note that index '3' is defined twice, and keep its final value of 13.
