The coherence time, usually designated τ, is calculated by dividing the coherence length by the phase velocity of light in a medium; approximately given by = where λ is the central wavelength of the source, Δν and Δλ is the spectral width of the source in units of frequency and wavelength respectively, and c is the speed of light in vacuum.
Dissolving Classroom (Japanese: 溶解教室, Hepburn: Yōkai Kyōshitsu) is a Japanese horror manga series written and illustrated by Junji Ito.It was serialized in Comic Motto! from March 2013 to October 2014 and published in a single volume in December 2014.
A panel is an individual frame, or single drawing, in the multiple-panel sequence of a comic strip or comic book, as well as a graphic novel. A panel consists of a single drawing depicting a frozen moment. [1] When multiple panels are present, they are often, though not always, separated by a short amount of space called a gutter.
Light also has a polarization, which is the direction in which the electric or magnetic field oscillates. Unpolarized light is composed of incoherent light waves with random polarization angles. The electric field of the unpolarized light wanders in every direction and changes in phase over the coherence time of the two light waves.
Impressionistic backgrounds are common, as are sequences in which the panel shows details of the setting rather than the characters. Panels and pages are typically read from right to left, consistent with traditional Japanese writing. Iconographic conventions in manga are sometimes called manpu (漫符, manga effects) [D 1] (or mampu [D 2]).
[61] At a SXSW Q&A panel, Armisen said that to do "The Californians" accent: "You have to pronounce every single consonant and vowel." [62] According to Hader, the accents were not originally so pronounced, but Armisen spontaneously changed his almost to the point of incoherence the first time the sketch aired live. [63]
Coherence time is actually a statistical measure of the time duration over which the channel impulse response is essentially invariant, and quantifies the similarity of the channel response at different times. In other words, coherence time is the time duration over which two received signals have a strong potential for amplitude correlation.
Photon detections as a function of time for a) antibunching (e.g. light emitted from a single atom), b) random (e.g. a coherent state, laser beam), and c) bunching (chaotic light). τ c is the coherence time (the time scale of photon or intensity fluctuations).
