Difference method

The different methods of manufacturing sulphuric acid are essentially the same in principle and consist of three distinct processes  [Pg.296]

A rather different method from the preceding is that based on the rate of dissolving of a soluble material. At any given temperature, one expects the initial dissolving rate to be proportional to the surface area, and an experimental verification of this expectation has been made in the case of rock salt (see Refs. 26,27). Here, both forward and reverse rates are important, and the rate expressions are [Pg.577]

For these different methods, the detection is either by volume measurement, gravimetry, conductimetry or coulometry. [Pg.32]

For all the different methods of chemical visualization, a lar e number of special techniques arc available, depending on the purpose of visualization. These software programs can be installed on a local computer or can be operated via the Internet. An ovemew of these programs is given in Section 2.12.3. [Pg.130]

It will be seen that each method for surface area determination involves the measurement of some property that is observed qualitatively to depend on the extent of surface development and that can be related by means of theory to the actual surface area. It is important to realize that the results obtained by different methods differ, and that one should in general expect them to differ. The problem is that the concept of surface area turns out to be a rather elusive one as soon as it is examined in detail. [Pg.572]

Surface Tension Values as Obtained by Different Methods [Pg.35]

A distinction must be made between the different methods with respect to the temperature attained during combustion because the reaction  [Pg.31]

The calibration of the SPATE system can be carried out by two different methods  [Pg.410]

The lead discovery process is depicted in Figure 10.4-4 and shows how the different methods are interconnected. A lead structure can be discovered by serendipity. In rational drug design all information available about a target serves to direct [Pg.605]

Fig. 1. CPU times (in hours) for 1 ps MD runs for various proteins using three different methods, direct velocity Verlet with a time-step 0.5 fs, r-RESPA with direct evaluation of electrostatic forces and an overall time-step of 4.0 fs, and r-RESPA/TFMM with an overall time-step 4.0 fs (combination of (2,2,2,2) in force breakup).The energy conservation parameter log AE for the three methods are comparable. The CPU time (hours) is for RISC6000 /MODEL 590 computer. Fig. 1.

Here, the obvious choice would be y = y". However, as was first proposed in [8] for a different method described at the end of this section, it turns out to be favorable to take an averaged position value [Pg.423]

Equation (23) represents the essence of the finite-difference method [21, 22, 23, 24], [Pg.184]

The basic ideas underlying most, if not all, of tire energy-difference methods follow [Pg.2188]

The gradient of the PES (force) can in principle be calculated by finite difference methods. This is, however, extremely inefficient, requiring many evaluations of the wave function. Gradient methods in quantum chemistiy are fortunately now very advanced, and analytic gradients are available for a wide variety of ab initio methods [123-127]. Note that if the wave function depends on a set of parameters X], for example, the expansion coefficients of the basis functions used to build the orbitals in molecular orbital (MO) theory. [Pg.267]

For the determination of the approximated solution of this equation the finite difference method and the finite element method (FEM) can be used. FEM has advantages because of lower requirements to the diseretization. If the material properties within one element are estimated to be constant the last term of the equation becomes zero. Figure 2 shows the principle discretization for the field computation. [Pg.313]

There are many algorithms for integrating the equations of motion using finite difference methods, several of which are commonly used in molecular dynamics calculations. All algorithms assume that the positions and dynamic properties (velocities, accelerations, etc.) can be approximated as Taylor series expansions  [Pg.369]

There are difficulties of detecting defects in axial canal because of solid sediment layer of 1. 2 mm thick on the canal surface. When using known defectoscope devices a preliminary labor-intensive mechanical treatment of the axial canal surface is needed. The experience of application of different methods of rotor axial canal control in multifunction automatic device ROTOR - K has pointed to the fact that the most effective method is eddy current one [1]. All the dangerous cracks were just detected by the eddy current method, the part of the cracks were not [Pg.346]
