Fill parameter

Models which include exact exchange are often called hybrid methods, the names Adiabatic Connection Model (ACM) and Becke 3 parameter functional (B3) are examples of such hybrid models defined by eq. (6.35). The <, d and parameters are determined by fitting to experimental data and depend on the form chosen for typical values are a 0.2, d 0.7 and c 0.8. Owing to the substantially better performance of such parameterized functionals the Half-and-Half model is rarely used anymore. The B3 procedure has been generalized to include more filling parameters, however, the improvement is rather small. 

Space-filling parameter (and curves). The space-filling parameter introduced by Laves (1956) and by Parthe (1961) is an index which may be useful in studying the relationships between atomic dimensions and structure. For a compound it is defined by the ratio between the volume of atoms, assumed as spheres of well-defined radii in a unit cell, and the volume of the unit cell itself. 

Typical space-filling parameters of elemental structures are the following cF4-Cu type p = 0.740... 

The simple structure of this semimetal, not very compact, has a space filling parameter p = 0.524. 

The filler is the focal point and the most critical component on any production line. This piece of equipment will always adversely affect the production when it is not operating. Filler downtime can never be recovered therefore, it should be minimized. All other equipment on the line can be sized or adequately positioned to allow the filler to continue running when downtime occurs. In addition, the performance of the filler with respect to filling parameters remains constant when the filler operates without interruption. This constant performance is critical when determining equipment line speed and relationships. The rate-limiting factor of the whole line depends on the performance of the filler. 

Available is a programmable logic-controlled machine for a one-stroke machine with no pulsing of resin flow and full control of all filling parameters. It uses hydraulically driven and computer-controlled delivery cylinders, with the catalyst cylinder mechanically connected to the material cylinder, for accurate and complete dosage of the components. The system... 

Two other use fill parameters are the component crit-icahty and what we here refer to as the improvement potential . Component criticality is especially helpful in the base case (no maintenance action) when replacement for some components is a relevant option, because it quantifies the benefit of improving one component compared to the others. Component criticality or importance is generally defined as the effect the component state has on the system state, but can be measured in different ways. In Isaksen (2008) it is argued that a good and simple measure is an evaluation of the covariance between the component and the system.

Empty geotextile tubes are normally described in terms of either theoretical diameter (this occurs in Europe, Africa and Asia) or circumference (this occurs in the Americas) (Fig. 20.5(a)). However, these two parameters are of little practical use from an engineering perspective because it is the tube parameters when filled that are of engineering importance. Fig. 20.5(b) shows the filled parameters of importance, while Table 20.1 lists the approximate values of these parameters when the geotextile mbe has been filled to maximum fill height, ie, at = 0.5 Dj. The ratio of filled height to theoretical... 

For maximum stability geotextile tubes should be filled to maximum height. Table 20.1 fists the filled parameters of geotextile tubes when filled to maximum height. This results in a dense unit that is highly stable. It also ensures that the sand fill within the geotextile tube cannot liquefy during storm activity and move within the mbe, thus...
