A hodograph is a diagram that gives a vectorial visual representation of the movement of a body or a fluid. It is the locus of one end of a variable vector, with the other end fixed. [1] The position of any plotted data on such a diagram is proportional to the velocity of the moving particle. [2] It is also called a velocity diagram.
Shock polar in the pressure ratio-flow deflection angle plane for a Mach number of 1.8 and a specific heat ratio 1.4. The minimum angle, , which an oblique shock can have is the Mach angle = (/), where is the initial Mach number before the shock and the greatest angle corresponds to a normal shock.
The Nyquist plot for () = + + with s = jω.. In control theory and stability theory, the Nyquist stability criterion or Strecker–Nyquist stability criterion, independently discovered by the German electrical engineer Felix Strecker [] at Siemens in 1930 [1] [2] [3] and the Swedish-American electrical engineer Harry Nyquist at Bell Telephone Laboratories in 1932, [4] is a graphical technique ...
On the momentum hodograph in the relevant section above, B is readily seen to connect the origin of momenta with the center of the circular hodograph, and to possess magnitude A/L. At perihelion, it points in the direction of the momentum. The vector B is denoted as "binormal" since it is perpendicular to both A and L. Similar to the LRL vector ...
Texas executed Steven Nelson for the 2011 murder of the Rev. Clint Dobson Wednesday night. It is the second execution of the year in the nation.
Hodograph plot of wind vectors at various heights in the troposphere, which is used to diagnose vertical wind shear Main article: Wind shear Wind shear, sometimes referred to as wind gradient , is a difference in wind speed and direction over a relatively short distance in the Earth's atmosphere.

Deming explained that these rankings reflect the market’s response to demands for colleges to focus more on career readiness and employment outcomes.
De Selliers, the head of both Leonidas and Belgian chocolate federation Choprabisco, called the price increase over the last two and a half years "absolutely spectacular." The unprecedented prices ...
