Toward the end of the nineteenth century Lorentz modeled the electron by a spherical shell of uniform surface charge density and set about the difficult task of deriving the equation of motion of this electron model by determining, from Maxwell's equations and the Lorentz force law, the retarded...

A rise in w will lead to an equiproportionate increase in cy and hence will have no impact on h. Now suppose Equation (41) is changed to read cy+co′r=0.5w+ϕw(0.5−h)−wq. Here ϕ represents the gender gap, or the ratio of female to male wages. Males and females each...
Power for backleading (blue markers) was measured at one hand and multiplied by two for both hands. Power for step-to-step transitions (black markers) was calculated at mean step lengths for each participant and backleading condition using the equation in Donelan et al.23. (a) Mean ...
The Hill equation was fit to the data obtained for each individual fiber (r2 > or = 0.98). For the SED group, fiber force-velocity parameters varied (P type IIa > type I; maximal shortening velocity (Vmax, defined as y-intercept of force-velocity relationship), type IIx = type IIa >...
The power can also be calculated using the force, resulting in λlgv0 + λv0^3. The change in energy can be determined by considering the kinetic energy of the chain and the potential energy of each infinitesimally small element. However, using the equation F = dp ...
where we have introduced an excitation force coefficient Γ(ω) and a phase angle ϕ(ω), both frequency dependent and that can be obtained directly from the boundary integral equation method described in the previous chapter (see Section 2.4.1). We note that the excitation force is directly...
open. We fitted Bolt’s velocity in Beijing 2008 and Berlin 2009 using an equation with the same form as Eq. 2 , but with three parameters to be fitted to his position as a function of time. We assume that the velocity is given by v t = a 1 − e −ct − bt, 3 an...
The method obtains least-squares solution of static equation formulated with variables from robot configuration and contact angle, and traction force. The method is validated through simulations that show a good agreement of the estimated normal force with the real one. Finally, we present the ...
The relationship between the horizontal trapping force and the beam power was predetermined, with the aid of the Stokes equation, from the critical beam power at the moment of the start of the displacement of a particle trapped by a gradually attenuating beam against the frictional force of the...
