The Mendeley research catalog is a crowdsourced database of research documents. Researchers have uploaded nearly 100M documents into the catalog with additional contributions coming directly from subject repositories like Pubmed Central and Arxiv.org or web crawls. Free Mendeley [98] Merck Index: Chemistry, biology, pharmacology: Also available ...
Routing calculates good paths through a network for information to take. For example, from node 1 to node 6 the best routes are likely to be 1-8-7-6, 1-8-10-6 or 1-9-10-6, as these are the shortest routes. Routing is the process of selecting network paths to carry network traffic. Routing is performed for many kinds of networks, including ...
The decibel originates from methods used to quantify signal loss in telegraph and telephone circuits. Until the mid-1920s, the unit for loss was miles of standard cable (MSC). 1 MSC corresponded to the loss of power over one mile (approximately 1.6 km) of standard telephone cable at a frequency of 5000 radians per second (795.8 Hz), and matched closely the smallest attenuation detectable to a ...

In the late 1980s, less than 1% of the world's technologically stored information was in digital format, while it was 94% in 2007, with more than 99% by 2014. [52] It is estimated that the world's capacity to store information has increased from 2.6 (optimally compressed) exabytes in 1986, to some 5,000 exabytes in 2014 (5 zettabytes). [52] [53]
Bell Labs was the research arm of American Telephone and Telegraph (AT&T). The three individuals credited with the invention of the transistor were William Shockley, John Bardeen and Walter Brattain. The introduction of the transistor is often considered one of the most important inventions in history. [1] [2]
On the right is a test rover for the Mars Science Laboratory, which landed Curiosity on Mars in 2012. Robotics is the interdisciplinary study and practice of the design, construction, operation, and use of robots. [1]
In this case, the function is addition, and applying it to the argument list (1 2) yields the answer 3. This is the result of the evaluation. The symbol foo evaluates to the value of the symbol foo. Data like the string "123" evaluates to the same string. The list (quote (1 2 3)) evaluates to the list (1 2 3).
