An example of a vector is velocity, as opposed to speed that is a scalar quantity. If we describe space in terms of x, y, and z components, then the velocity has a magnitude, but a component or percentage of the total magnitude is found within each of the x, y, and z directions....
An example of the input/output characteristics of a scalar quantizer is shown in Fig. 1. Sign in to download full-size image FIGURE 1. Input/output characteristics of a scalar quantizer. Define the quantizer error e(u) by e(u)=Q(u)−u. This quantity is of crucial importance in descr...
1 Which is a vector quantity?(1) electric charge(2) electric field strength(3) electric potential difference(4) electric resistance5 A machine launches a tennis ball at an angle of25° above the horizontal at a speed of 14 metersper second.The ball returns to level ground.Which combination...
The age of the ice is a good proxy for ice thickness, and ice thickness or volume is a far better metric than area for evaluating the health of the ice. Notice that the last remaining area of thick, old ice, is along the north shore of Greenland and the northwest shores of the isla...
Furthermore, from a physical point of view, one can also think at the Riemann-Silberstein field reformulation of the electromagnetism43 in terms of a complex vector that combines the electric field E, as the real part, and the magnetic field B, as the imaginary part, in order to put in ...
Momentum is vector quantity, meaning that the direction of the object is important in the calculation. An object can have both vertical and horizontal velocity. Therefore, the magnitude and direction of the velocity must be taken into account when describing an object’s momentum. For example, an...

Consider, for example, a functional with a symmetric positive matrix (92)A = ∫t1,Vt2{12B:uu+ϕ⋅−a∂∂tu+L∇2u}dV dt. The Euler–Lagrange equation of this functional with respect to u provides the following representation for the field vector u (93)u=−B−1a∂∂t...
The main assumption implied is the proportional hazards assumption, which is that the hazard ratio, that is the ratio of the hazard function to the baseline hazard, is constant over time. The use of the exponential function ensures that the hazard is positive. The quantity that is estimated ...
