Rōnin

A rōnin (浪人) was a samurai with no lord or master during the feudal period (1185–1868) of Japan. A samurai became masterless from the death or fall of his master, or after the loss of his master's favor or privilege.

In modern Japanese usage, the term also describes a salaryman who is "between employers" or a secondary school graduate who has not yet been admitted to university.

Etymology

The word rōnin literally means "wave man". It is an idiomatic expression for "vagrant" or "wandering man", someone who is without a home. The term originated in the Nara and Heian periods, when it referred to a serf who had fled or deserted his master's land. It then came to be used for a samurai who had no master. (Hence, the term "wave man" illustrating one who is socially adrift.)

The word "浪人" means a "drifter" or a "wanderer", i.e. "he who drifts/wanders".

Status

According to the Bushido Shoshinshu (the Code of the Samurai), a samurai was supposed to commit seppuku (also "hara kiri" — ritual suicide) upon the loss of his master. One who chose not to honor the code was "on his own" and was meant to suffer great shame. The undesirability of rōnin status was mainly a discrimination imposed by other samurai and by daimyo, the feudal lords.

Sensor

In the broadest definition, a sensor is an object whose purpose is to detect events or changes in its environment, and then provide a corresponding output. A sensor is a type of transducer; sensors may provide various types of output, but typically use electrical or optical signals. For example, a thermocouple generates a known voltage (the output) in response to its temperature (the environment). A mercury-in-glass thermometer, similarly, converts measured temperature into expansion and contraction of a liquid, which can be read on a calibrated glass tube.

Sensors are used in everyday objects such as touch-sensitive elevator buttons (tactile sensor) and lamps which dim or brighten by touching the base, besides innumerable applications of which most people are never aware. With advances in micro machinery and easy-to-use micro controller platforms, the uses of sensors have expanded beyond the most traditional fields of temperature, pressure or flow measurement, for example into MARG sensors. Moreover, analog sensors such as potentiometers and force-sensing resistors are still widely used. Applications include manufacturing and machinery, airplanes and aerospace, cars, medicine, and robotics.it is also included in our day-to-day life.

Detector (film)

Detector is a 2000 Norwegian comedy film directed by Pål Jackman from a screenplay by Erlend Loe. It was entered into the 23rd Moscow International Film Festival. It was one of the greatest domestic film successes in Norway for many years, and is considered to be the start of the Norwegian cinemas bloom that occurred in the 2000s.

Hermetic detector

In particle physics, a hermetic detector (also called a 4π detector) is a particle detector designed to observe all possible decay products of an interaction between subatomic particles in a collider by covering as large an area around the interaction point as possible and incorporating multiple types of sub-detectors. They are typically roughly cylindrical, with different types of detectors wrapped around each other in concentric layers; each detector type specializes in particular particles so that almost any particle will be detected and identified. Such detectors are called "hermetic" because they are constructed so as the motion of particles are ceased at the boundaries of the chamber without any moving beyond due to the seals; the name "4π detector" comes from the fact that such detectors are designed to cover nearly all of the 4π steradians of solid angle around the interaction point; in terms of the standard coordinate system used in collider physics, this is equivalent to coverage of the entire range of azimuthal angle () and pseudorapidity (). In practice, particles with pseudorapidity above a certain threshold cannot be measured since they are too nearly parallel to the beamline and can thus pass through the detector. This limit on the pseudorapidity ranges which can be observed forms part of the acceptance of the detector (i.e. the range of phase space which it is able to observe); broadly speaking, the main design objective of a hermetic detector is to maximise acceptance, i.e. to ensure that the detector is able to measure as large a phase space region as possible.
