Static weight function

Variously defined functions have been proposed and used for W, in Eq. (4). These include (6) the static weight function - the solution of the equation adjoint to Eq. (3) the kinetic weight function - - the solution of the equation adjoint to the w-mode Boltzmann equation [Eq. (17)] and the dynamic weight function, which equals unity If the weighting function is selected as the importance function, i.e., the solution of the adjoint equation... 

In the MWDA, the weight function is determined by requirement that the direct correlation function be reproduced in the uniform limit. In the GELA, the effective liquid state is required to yield both the direct correlation function and the free energy of the uniform liquid. These WDAs, especially the GELA, give among the most accurate SEE predictions for hard spheres. A further modification of the MWDA has been recently proposed that incorporates information about the static lattice into the functional [127]. 

As for many immobilised enz3nnes, the hydraulic behaviour Is not adequately described by classical fluid mechanics. It was, therefore, necessary to develop a detailed mathematical model of the column hydraulics which together with a laboratory test procedure, would provide data on the basic mechanical properties of the enzyme pellet. The model Is based on a force balance across a differential element of the enzyme bed. The primary forces involved are fluid friction, wall friction, solids cohesion, static weight and buoyancy. The force balance Is integrated to provide generating functions for fluid pressure drop and solid stress pressure down the length of the column under given conditions. 

Apparent Mass of Seated Persons. The apparent mass is often used to describe the response of the body at the point of stimulation rather than the mechanical impedance, and is the complex ratio between the dynamic force applied to the body and the acceleration at the interface where vibration enters the body. It is commonly expressed as a function of frequency, and is equal to the static weight of a subject in the limiting case of zero ftequency when Ae legs are supported to move in unison with the torso. The influence of posture, muscle tension, and stimulus magnitude on the... 

A nuclear magnetic resonance line is usually found to have one of two ideal lineshapes - Gaussian, or more often, Lorentzian. A Gaussian line is found when there is a random distribution of static fields within the sample. A Lorentzian line by contrast arises because the spin lifetime follows a first-order decay law. Weighting functions can be applied to a free-induction decay to generate... 

The electrostatic energy gives the average value of the molecular electrostatic potential of B(A) weighted with the static distribution function of A(B). It also follows, as in (23), that... 

Although some polymers may be satisfactory when used under the stress of static loads, they may fail when subjected to impact. The impact resistance, or resistance to brittle fracture, is a function of the molecular weight of a polymer. Thus uhmwpe is much more resistant to impact failure than general purpose high-density polyethylene (hdpe). The impact resistance of brittle polymers is also increased by the addition of plasticizers. Thus polyvinyl chloride (PVC), plasticized by relatively large amounts of dioctyl phthalate, is much less brittle than unplasticized rigid PVC.
