Cyclothymia (/ ˌ s aɪ k l ə ˈ θ aɪ m i ə /, siy-kluh-THIY-mee-uh), also known as cyclothymic disorder, psychothemia / psychothymia, [5] bipolar III, [6] affective personality disorder [7] and cyclothymic personality disorder, [8] is a mental and behavioural disorder [9] that involves numerous periods of symptoms of depression and periods of symptoms of elevated mood. [3]
The Mach number (M or Ma), often only Mach, (/ m ɑː k /; German:) is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound. [1] [2] It is named after the Austrian physicist and philosopher Ernst Mach. =, where: M is the local Mach number,
Dimensionless numbers (or characteristic numbers) have an important role in analyzing the behavior of fluids and their flow as well as in other transport phenomena. [1] They include the Reynolds and the Mach numbers, which describe as ratios the relative magnitude of fluid and physical system characteristics, such as density, viscosity, speed of sound, and flow speed.
Numerous notable people have had some form of mood disorder. This is a list of people accompanied by verifiable sources associating them with some form of bipolar disorder (formerly known as "manic depression"), including cyclothymia, based on their own public statements; this discussion is sometimes tied to the larger topic of creativity and mental illness. In the case of dead people only ...
The drag-divergence Mach number (not to be confused with critical Mach number) is the Mach number at which the aerodynamic drag on an airfoil or airframe begins to increase rapidly as the Mach number continues to increase. [1] This increase can cause the drag coefficient to rise to more than ten times its low-speed value.
The 1-vs-2 cycles conjecture or 2-cycle conjecture is an unproven computational hardness assumption asserting that solving the 1-vs-2 cycles problem in the massively parallel communication model requires at least a logarithmic number of rounds of communication, even for a randomized algorithm that succeeds with high probability (having a ...
A recent study found that adding 111 minutes of daily walking could help you live 11 years longer. Here's experts want you to know about walking's benefits.
In aerodynamics, the normal shock tables are a series of tabulated data listing the various properties before and after the occurrence of a normal shock wave. [1] With a given upstream Mach number, the post-shock Mach number can be calculated along with the pressure, density, temperature, and stagnation pressure ratios.
