nUbuntu or Network Ubuntu was a project to take the existing Ubuntu operating system LiveCD and Full Installer and remaster it with tools needed for penetration testing servers and networks. The main idea is to keep Ubuntu's ease of use and mix it with popular penetration testing tools. Besides usage for network and... |
https://en.wikipedia.org/wiki/Hardness | In materials science, hardness (antonym: softness) is a measure of the resistance to plastic deformation, such as an indentation (over an area) or a scratch (linear), induced mechanically either by pressing or abrasion. In general, different materials differ in their hardness; for example hard metals such as titanium ... |
https://en.wikipedia.org/wiki/Heisenbug | In computer programming jargon, a heisenbug is a software bug that seems to disappear or alter its behavior when one attempts to study it. The term is a pun on the name of Werner Heisenberg, the physicist who first asserted the observer effect of quantum mechanics, which states that the act of observing a system inevit... |
https://en.wikipedia.org/wiki/STEbus | The STEbus (also called the IEEE-1000 bus) is a non-proprietary, processor-independent, computer bus with 8 data lines and 20 address lines. It was popular for industrial control systems in the late 1980s and early 1990s before the ubiquitous IBM PC dominated this market. STE stands for STandard Eurocard.

General discrete-time memoryless relay channel
A discrete memoryless single-relay channel can be modelled as four finite sets, and , and a conditional pro... |
https://en.wikipedia.org/wiki/Power%20optimization%20%28EDA%29 | Power optimization is the use of electronic design automation tools to optimize (reduce) the power consumption of a digital design, such as that of an integrated circuit, while preserving the functionality.
Introduction and history
The increasing speed and complexity of today’s designs implies a significant increase ... |
https://en.wikipedia.org/wiki/Atomic%20layer%20epitaxy | Atomic layer epitaxy (ALE), more generally known as atomic layer deposition (ALD), is a specialized form of thin film growth (epitaxy) that typically deposit alternating monolayers of two elements onto a substrate. The crystal lattice structure achieved is thin, uniform, and aligned with the structure of the substrate... |
https://en.wikipedia.org/wiki/Chemical%20beam%20epitaxy | Chemical beam epitaxy (CBE) forms an important class of deposition techniques for semiconductor layer systems, especially III-V semiconductor systems. This form of epitaxial growth is performed in an ultrahigh vacuum system. The reactants are in the form of molecular beams of reactive gases, typically as the hydride or... |
