All the DIRECTION, POINT and ELEMENTARY CURVE entities are located in the xy-plane. The rotation axis is defined by the positive x-axis. The y-values must be greater or equal zero. The rotation angle must be greater than zero and less or equal 2ir. 

The local y-axis is calculated by dir y = dir xz dir x and subsequently the local z-axis by dir z = dir x dir y. Material is assumed to be inside the ROTATIONAL.SWEEP.

Most fluorescent substances have rigid structures associated with fused aromatic rings and their fluorescence intensity is practically independent of the viscosity of the environment (4). On the other hand, their rotational movement as a whole will, of course, depend upon the local environment and since such rotations sweep out a larger volume than would be the case for auramine O, for example (i.e., larger V in eq. 2), so that larger domains in the polymeric system can be studied. Any fluorescent system will exhibit a polarization of fluorescence by virtue of the fact that the fluorescent molecules are anisotropic in regard both to emission and to absorption. This anisotropy can be described by fixed axes within the molecule, namely the dichroic axis of the molecule and the emission... 

Solvent-laden meal enters the DT at a temperature of 60°C, and it contains 25% to 35% (w/w) of solvent. The solvent-laden meal is stirred across the surface of the predesolventizing trays by the rotating sweeps. As the heat is transferred into the meal layer by conduction, a shallow layer of 150-to-300-mm meal depth is held above each tray. The solvent-laden meal temperature is increased to approximately 68°C and approximately 10% to 25% of the solvent is evaporated on the predesolventizing trays. 

The material exits the predesolventizing trays of the DT and falls onto the top countercurrent tray. This is perhaps the most critical tray of the DT. As most of the heat is transferred into the meal layer by condensation of direct steam, a deep layer of 700-to 1000-mm meal depth is held above the tray. The solvent-laden meal is stirred above the top countercurrent tray by the rotating sweeps. The direct steam passes from below up through apertures in the countercurrent tray. As the direct steam penetrates the upper meal layer, it reaches the solvent-laden meal and condenses, providing direct latent heat to evaporate solvent. The solvent evaporates and exits the meal layer as vapor. The condensation of steam causes the meal exiting the tray to be wet, typically in the range of 17-21% moisture. After the majority of the solvent evaporates, the meal temperature increases by direct and indirect steam... 

The recently introduced rotation sweep spectroscopy [11] is based on the realization that decreased rotor size provides acceleration proportional to the inverse cube of the rotor diameter... 

Unlike correlation spectroscopy based on spin diffusion, the adiabatic version enables, in principle, almost full exchange of magnetization between the two spins. As a result, the entire signal intensity will reside in the cross-peaks. Violation of the adiabaticity is characterized by the appearance of a diagonal peak and can be expected to occur if the rotation sweep is too fast compared to the interaction between spins. While numerical simulations indicate possible linear dependencies of the polarization transfer coefficient on spin coupling and the rate of the sweep over a range of practical values, the validity of this assumption remains to be tested. Here we present a semi-quantitative example of a relayed polarization transfer process.

In rotational sweeping, objects are generated through the rotation of surfaces, as well as closed or open, but restricted, contour fines around a predefined axis. The axis may not cut the surface or contour. A prismatic body originates from the expansion of a closed contour fine. Shells or full bodies can be generated with sweep operations. With sweep-generated shells, movement analysis and assembly inspection can occur. The analysis takes place by the bodies movement along a curve in space. 

In addition to primitive algebraic surfaces, more general surfaces with a simple kinematic generation, such as sweep surfaces, revolved surfaces (rotation sweep), extrusion surfaces (translation sweep), pipe surfaces, are directly compatible to CAD models. Fitting those surfaces to segmented data points or mesh is critical to the reconstruction of surface models and support of parameterization (Lukacs et al., 1998). 

ENTITY SWEEP = CLASS( LINEAR SWEEP, ROTATIONAL SWEEP ) ... 

The entity SWEEP consists of a class containing the entities LINEAR SWEEP and ROTATIONAL SWEEP. 

A ROTATIONAL-.SWEEP (see Figure 24 on page 129) is a construct primitive. It is defined by the swept area and a rotation angle. The swept area is composed of a list of ordered lists of CONTOUR ELEMENT references. Every list of CONTOUR ELEMENT references describes a closed contour that must not intersect itself. There must be at least one list of CONTOUR ELEMENT references i.e. the outer bound of the swept area. Subsequent lists indicate inner bounds i.e. holes.
