Some aspects of alignment and orientation have been considered for femtochemistry experiments. Elementary theoretical descriptions of the time evolution of alignment and angular momenta have been discussed and related to the radial and angular parts of the potential-energy surface. Applications to ICN unimolecular dissociation, H + C 0 2 ‘oriented’ bimolecular reaction, and crossings between di...

Ax, A = amplitude of stroke amplitude in x direction, m, and orientation angle, deg CL, CL = lift coefficient and its average over flapping cycles CD, CD = drag coefficient and its average over flapping cycles CPW, CPW = input power coefficient and its average over flapping cycles c, h = chord and thickness of the plate, m; c is chosen as characteristic length Re = Uc v , Reynolds number, v is ...

We investigated the angular dependence of magnetization reversal in epitaxial MnPd/Fe bilayers grown on MgO 001 using combined longitudinal and transverse magneto-optical Kerr effect. Square loops, asymmetrically shaped loops, and double-shifted loops were observed as the field orientation was varied from parallel to perpendicular to the bias direction. Additionally, including the effect of an ...

Rotational control and swing suppression of a crane suspended load model with traveling disturbance are studied. A rotational free rigid body suspended by a single rope is controlled using three inertia rotors. The end-supporting-point of the single rope is forced to be traveled as disturbance. Control angles and angular velocities are derived from measured data of fiber optic gyros installed o...

Using a complex representation of the Debney–Kerr–Schild (DKS) solutions and the Kerr theorem we analyze the boosted Kerr geometries and give the exact and explicit expressions for the metrics, the principal null congruences, the coordinate systems and the location of the singularities for arbitrary value and orientation of the boost with respect to the angular momentum. In the limiting, ultrar...

The visual illusion of apparent rigid rotation was produced by sequential alternation of two views of the same object in different orientations. The minimum stimulus-onset asynchrony required for the appearance of rigid rotation was a linearly increasing function of the angular difference in orientation between the two views. Variation in the size of the object affected the zero-intercept of th...

PURPOSE In diffusion MRI, a technique known as diffusion spectrum imaging reconstructs the propagator with a discrete Fourier transform, from a Cartesian sampling of the diffusion signal. Alternatively, it is possible to directly reconstruct the orientation distribution function in q-ball imaging, providing so-called high angular resolution diffusion imaging. In between these two techniques, ac...

A CT-based navigation system is helpful to evaluate the reamer shaft and the impactor position/orientation during unilateral total hip arthroplasty (THA). The main objective of this study is to determine the accuracy of the Navitrack system by measuring the implant's true anteversion and inclination, based on pre- and postoperative CT scans (n = 9 patients). The secondary objective is to evalua...

In Augmented Reality (AR), see-through Head Mounted Displays (HMDs) superimpose virtual 3D objects over the real world. They have the potential to enhance a user's perception and his interaction with the real world. However, many AR applications will not be accepted until we can accurately align virtual objects in the real world. One step to achieve better registration is to improve the trackin...

We study the dynamics of galactic disk formation and evolution in ‘realistic’ Λ cold dark matter haloes with idealized baryonic initial conditions. We add rotating spheres of hot gas at z = 1.3 to two fully cosmological dark-matter-only halo (re)simulations. The gas cools according to an artificial and adjustable cooling function to form a rotationally supported galaxy. The simulations evolve i...
