### What is the hydrodynamic radius (R

By definition then, the DLS measured radius is the radius of a hypothetical hard sphere that diffuses with the same speed as the particle under ... established by rotating the protein about the geometric center. ∑ ∑ = i 2 i i 2 g m r m R Figure 2: Comparison of hydrodynamic radius (R H) to other radii for ...

### CURVES Section I. SIMPLE HORIZONTAL CURVES

The difference is that one is computed by the arc definition and the other by the chord definition. Since the two curves have different radii, the other elements are also different. 5,730-Foot Definition Some engineers prefer to use a value of 5,730 feet for the radius of a l-degree curve, and the arc ...

### Complex Shape Design

Definition of Continuity Continuity describes the curvature changes between connected curves or surfaces. Molded components typically require high standards for continuity between surfaces, including the surfaces formed by radii between larger

### Chapter 13 Geometry of the Circle

If A, B, and C are points of circle O, then , , and are radii of the circle. Since the definition of a circle states that all points of the circle are equidistant from its center, OA * OB * OC.

### Radius of curvature metrology for segmented mirrors

Thus, for a segmented mirror, it is useful to determine how errors in the relative radii affect the system performance. The Strehi ratio is a useful quantity for assessing the performance of a diffraction-limited optical system. A qualitative definition of the Strehi ratio is. intensity of onaxis ...

### HORIZONTAL AND VERTICAL CURVES

This definition, illustrated in figure 11-4, states that the degree of curve is the central angle formed by two radii that extend from the center of a circle to the ends of an arc measuring 100 feet long (or 100 meters long if you are using metric units).
