https://en.wikipedia.org/wiki/Methyl%20cellulose | Methyl cellulose (or methylcellulose) is a compound derived from cellulose. It is sold under a variety of trade names and is used as a thickener and emulsifier in various food and cosmetic products, and also as a bulk-forming laxative. Like cellulose, it is not digestible, non-toxic, and not an allergen.
In addition to... |
https://en.wikipedia.org/wiki/X-ray%20crystal%20truncation%20rod | X-ray crystal truncation rod scattering is a powerful method in surface science, based on analysis of surface X-ray diffraction (SXRD) patterns from a crystalline surface.
For an infinite crystal, the diffracted pattern is concentrated in Dirac delta function like Bragg peaks. Presence of crystalline surfaces results ... |
https://en.wikipedia.org/wiki/Water%20tunnel%20%28hydrodynamic%29 | A water tunnel is an experimental facility used for testing the hydrodynamic behavior of submerged bodies in flowing water. It functions similar to a recirculating wind tunnel, but uses water as the working fluid, and related phenomena are investigated, such as measuring the forces on scale models of submarines or lif... |
https://en.wikipedia.org/wiki/Tsallis%20entropy | In physics, the Tsallis entropy is a generalization of the standard Boltzmann–Gibbs entropy.
Overview
The concept was introduced in 1988 by Constantino Tsallis as a basis for generalizing the standard statistical mechanics and is identical in form to Havrda–Charvát structural α-entropy, introduced in 1967 within infor... |
https://en.wikipedia.org/wiki/Wireless%20Intelligent%20Network | Wireless Intelligent Network (also referred to as a WIN) is a concept developed by the TR-45 Mobile and Personal Communications Systems Standards engineering committee of the Telecommunications Industry Association (TIA). Its objective is to transport the resources of the Intelligent Network to the wireless network, ut... |
https://en.wikipedia.org/wiki/Vibrational%20partition%20function | The vibrational partition function traditionally refers to the component of the canonical partition function resulting from the vibrational degrees of freedom of a system. The vibrational partition function is only well-defined in model systems where the vibrational motion is relatively uncoupled with the system's othe... |
https://en.wikipedia.org/wiki/Branching%20quantifier | In logic a branching quantifier, also called a Henkin quantifier, finite partially ordered quantifier or even nonlinear quantifier, is a partial ordering
of quantifiers for Q ∈ {∀,∃}. It is a special case of generalized quantifier. In classical logic, quantifier prefixes are linearly ordered such that the value of a ... |
https://en.wikipedia.org/wiki/Interconnect%20agreement | An interconnect agreement is a business contract between telecommunications organizations for the purpose of interconnecting their networks and exchanging telecommunications traffic. Interconnect agreements are found both in the public switched telephone network and the Internet.
In the public switched telephone netwo... |
https://en.wikipedia.org/wiki/Brillouin%20and%20Langevin%20functions | The Brillouin and Langevin functions are a pair of special functions that appear when studying an idealized paramagnetic material in statistical mechanics. These functions are named after French physicists Paul Langevin and Léon Brillouin who contributed to the microscopic understanding of magnetic properties of matter... |
https://en.wikipedia.org/wiki/Mechanical%20resonance | Mechanical resonance is the tendency of a mechanical system to respond at greater amplitude when the frequency of its oscillations matches the system's natural frequency of vibration (its resonance frequency or resonant frequency) closer than it does other frequencies. It may cause violent swaying motions and potential... |
https://en.wikipedia.org/wiki/Electrical%20resonance | Electrical resonance occurs in an electric circuit at a particular resonant frequency when the impedances or admittances of circuit elements cancel each other. In some circuits, this happens when the impedance between the input and output of the circuit is almost zero and the transfer function is close to one.
Resonan... |
https://en.wikipedia.org/wiki/Acoustic%20resonance | Acoustic resonance is a phenomenon in which an acoustic system amplifies sound waves whose frequency matches one of its own natural frequencies of vibration (its resonance frequencies).
The term "acoustic resonance" is sometimes used to narrow mechanical resonance to the frequency range of human hearing, but since aco... |
