This product is the main reason for the rapid growth of EMC in the 1990s, both in size and value, from a company valued hundreds of millions of dollars to a multi-billion company. [1] Moshe Yanai managed the Symmetrix development from the product's inception in 1987 until shortly before leaving EMC in 2001, [ 2 ] and his Symmetrix development ...
UBS (for 1.21%), Foresea Life Insurance (for 1.14%), Yale University (for 0.95%), Hexie Health Insurance (for 0.80%), chairwoman Dong Mingzhu (for 0.73%) and a private equity fund (for 0.71%). [2] In 2001 Gree Group owned a 50.289% stake in Gree Electric. [10] Gree Group was also the largest shareholder of Gree Real Estate (SSE: 600185) until ...
A CMOS transistor NAND element. V dd denotes positive voltage.. In CMOS logic, if both of the A and B inputs are high, then both the NMOS transistors (bottom half of the diagram) will conduct, neither of the PMOS transistors (top half) will conduct, and a conductive path will be established between the output and Vss (ground), bringing the output low.
A LOW (0) output results only if all the inputs to the gate are HIGH (1); if any input is LOW (0), a HIGH (1) output results. A NAND gate is made using transistors and junction diodes. By De Morgan's laws , a two-input NAND gate's logic may be expressed as A ¯ ∨ B ¯ = A ⋅ B ¯ {\displaystyle {\overline {A}}\lor {\overline {B}}={\overline ...
For example, F 2 has a standard reduction potential of +2.87 V and Li + has −3.05 V: F 2 (g) + 2 e − ⇌ 2 F − = +2.87 V Li + + e − ⇌ Li (s) = −3.05 V. The highly positive standard reduction potential of F 2 means it is reduced easily and is therefore a good oxidizing agent.
Energy storage is the capture of energy produced at one time for use at a later time [1] to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery .
[1] An SDRF file is a tab-delimited file describing the relationships between samples, arrays, data, and other objects used or produced in a microarray investigation. For simple experimental designs, constructing the SDRF file is straightforward, and even complex loop designs can be expressed in this format.
The European market for the production of RDF have been grown fast due to the European landfill directive and the imposition of landfill taxes. Refuse derived fuel (RDF) exports from the UK to Europe and beyond are expected to have reached 3.3 million tonnes in 2015, representing a near-500,000 tonnes increase on the previous year.
