Successive integration

Given ng and 1(R, p), Eqs. (7.32a, b) can be integrated successively from r = R to a large value of r. By definition Z(R, p) = -y where yis the recombination probability in presence of scavenger. Only for the correct value of ydo the solutions of (7.32a, b) smoothly vanish asymptotically as r—-o° otherwise, they diverge. Thus, the mathematics is reduced to a numerical eigenvalue problem of finding the correct value of I(R, p). [Pg.235]

The angular mesh implemented consists of 6, 12, 24, 32, 50, or 74 points, capable of integrating successively higher order polynomials, or a uniform-area mesh of IV2 points. The radial integration is a modified Simpson s rule in the variable Inr, with outer radius rm , number of points, and logarithmic step selected as input. [Pg.61]

In order to determine the velocity now we need to know the coefficient of sliding friction k, and then would have to solve the integral equation above (or integrate successively over small time steps). It is clear, however, that... [Pg.28]

In practice, one usually puts several parameters into the trial function variational integral. Successful use of the variation method depends on the ability to make a good choice for the trial function. [Pg.210]

In recent decades, companies have been relentless in their drive to reduce headcount. The pressures to do so have often resulted from mergers and acquisitions where the justification for the merger was that overlapping and duplicated functions could be eliminated, thus resulting in the elimination of unnecessary jobs. However, such cuts may represent a false economy indeed merging two organizations may actually require a temporary increase in the number of service personnel so that the two different systems and cultures can be integrated successfully. [Pg.147]

Analog signals can be converted to digital codes by many methods, including integration, successive approximation, parallel (flash) conversion, delta modulation, pulse code modulation, and sigma-delta... [Pg.786]

It has developed a real time method to compare successive non-destructive inspections of the steam generator tubes in nuclear power plants. Each tube provides a safety barrier between the primary and secondary coolant circuits. Each steam generator contains several thousands of tubes whose structural integrity must be ensured through the lifetime of the plant, Therefore, Laborelec performs extensive nondestructive tests after each plant outage. [Pg.1022]

The heat of adsorption is an important experimental quantity. The heat evolution with each of successive admissions of adsorbate vapor may be measured directly by means of a calorimeter described by Beebe and co-workers [31]. Alternatively, the heat of immersion in liquid adsorbate of adsorbent having various amounts preadsorbed on it may be determined. The difference between any two values is related to the integral heat of adsorption (see Section X-3A) between the two degrees of coverage. See Refs. 32 and 33 for experimental papers in this area. [Pg.616]

W L Bragg [7] observed that if a crystal was composed of copies of identical unit cells, it could then be divided in many ways into slabs with parallel, plane faces whose distributions of scattering matter were identical and that if the pathlengths travelled by waves reflected from successive, parallel planes differed by integral multiples of the... [Pg.1364]

The IE and IM methods described above turn out to be quite special in that IE s damping is extreme and IM s resonance patterns are quite severe relative to related symplectic methods. However, success was not much greater with a symplectic implicit Runge-Kutta integrator examined by Janezic and coworkers [40],... [Pg.244]

The many approaches to the challenging timestep problem in biomolecular dynamics have achieved success with similar final schemes. However, the individual routes taken to produce these methods — via implicit integration, harmonic approximation, other separating frameworks, and/or force splitting into frequency classes — have been quite different. Each path has encountered different problems along the way which only increased our understanding of the numerical, computational, and accuracy issues involved. This contribution reported on our experiences in this quest. LN has its roots in LIN, which... [Pg.256]

A quite successful integrator for (16), which is based on the idea of operator splitting, is the PICKABACK scheme of Nettesheim et al. [19]. With the shorthand notation... [Pg.427]

In molecular dynamics, successive configurations of the system are generated by integrating Newton s laws of motion. The result is a trajectory that specifies how the positions and velocities of the particles in the system vary with time. Newton s laws of motion can be stated as follows ... [Pg.367]

Three such methods have been proposed by Morokuma and coworkers. The integrated MO + MM (IMOMM) method combines an orbital-based technique with an MM technique. The integrated MO + MO method (IMOMO) integrates two different orbital-based techniques. The our own n-layered integrated MO and MM method (ONIOM) allows for three or more different techniques to be used in successive layers. The acronym ONIOM is often used to refer to all three of these methods since it is a generalization of the technique. [Pg.201]

Because of the large difference in tp between successive molecular layers, each layer becomes complete at a relative pressure (plp°)g which is determined by the value of rp/kT for that layer, viz integral values). Each layer will therefore give rise to a step, such that the riser corresponds to the cooperative build-up of the layer and the tread to the transition between the layer and the next higher one. [Pg.84]

Closer examination reveals however that the Brunauer method is not fundamentally distinct from methods based on the Kelvin equation. As pointed out by de Vleesschauwer, equations such as (3.52) are not really employed in the integral form, inasmuch as the aim is to evaluate the surface areas of successive groups of cores. In effect Equation (3.52) is used after adaptation to small rather than infinitesimal increments and becomes... [Pg.149]
