Amplitude-comparison monopulse refers to a common direction finding technique. This method is used in monopulse radar, electronic warfare and radio astronomy. Amplitude monopulse antennas are usually reflector antennas. [1] Illustration of sum-difference beams.
A monolithic kernel is an operating system architecture with the entire operating system running in kernel space. The monolithic model differs from other architectures such as the microkernel [1][2] in that it alone defines a high-level virtual interface over computer hardware. A set of primitives or system calls implement all operating system ...
Volta potential. The Volta potential (also called Volta potential difference, contact potential difference, outer potential difference, Δψ, or "delta psi") in electrochemistry, is the electrostatic potential difference between two metals (or one metal and one electrolyte) that are in contact and are in thermodynamic equilibrium. Specifically ...
Current sources and sinks. In electromagnetism, current sources and sinks are analysis formalisms which distinguish points, areas, or volumes through which electric current enters or exits a system. While current sources or sinks are abstract elements used for analysis, generally they have physical counterparts in real-world applications; e.g ...
IMAP (Internet Messaging Access Protocol) • Emails are stored on the server. • Sent messages are stored on the server. • Messages can be synced and accessed across multiple devices. POP3 (Post Office Protocol) • Emails are stored on a single device. • Sent messages are stored on a single device. • Emails can only be accessed from a ...
The log-spectral distance (LSD), also referred to as log-spectral distortion or root mean square log-spectral distance, is a distance measure between two spectra. [1] The log-spectral distance between spectra and is defined as p-norm: where and are power spectra. Unlike the Itakura–Saito distance, the log-spectral distance is symmetric.
The Tsai hill criterion is interactive, i.e. the stresses in different directions are not decoupled and do affect the failure simultaneously. [2] Furthermore, it is a failure mode independent criterion, as it does not predict the way in which the material will fail, as opposed to mode-dependent criteria such as the Hashin criterion, or the Puck ...
Potentiometric sensor. A potentiometric sensor is a type of chemical sensor that may be used to determine the analytical concentration of some components of the analyte gas or solution. These sensors measure the electrical potential of an electrode when no current is present.
