Flexibility definition

Atom types represen t the chemical environment of an atom. The atom types associated with a given force field could be hard-wired to have specific vahiesand meaning. llyperChem also allows flexible definitions of the atom types and the associated chemical en vironmen Is. Th e ch em ical en viron men t of an atom (a set of rules for defining a type) and the default rules are in a standard ASCII text file, chem.nil. included with llyperChem. You can modify this file and compile it m a binary form that llyperChem... 

With foams, one is dealing with a gaseous state or phase of matter in a highly dispersed condition. There is a definite relationship between the practical application of foams and colloidal chemistry. Bancroft (4) states that adopting the very flexible definition that a phase is colloidal when it is sufficiently finely divided, colloid chemistry is the chemistry of bubbles, drops, grains, filaments, and films, because in each of these cases at least one dimension of the phase is very small. This is not a truly scientific classification because a bubble has a film round it, and a film may be considered as made up of coalescing drops or grains. ...

SHELXL (Sheldrick and Schneider, 1997) is often viewed as a refinement program for high-resolution data only. Although it undoubtedly offers features needed for that resolution regime (optimization of anisotropic temperature factors, occupancy refinement, full matrix least squares to obtain standard deviations from the inverse Hessian matrix, flexible definitions for NCS, easiness to describe partially... 

In such a flexible definition of engineering thermoplastics, the exact list and number of materials and/or families of materials will vary with the viewpoint of the specialist who prepares the list. For purposes of illustration, let us consider 13 thermoplastics, developed during the past decade or two, which are produced in small to moderate volume at medium to high prices, and are finding growing application in products where their superior properties justify their higher costs. Most of these descriptions of engineering thermoplastics are taken from the manufacturers bulletins and unpublished discussions with manufacturers and users of these materials.

Micro aerial vehicles are a class of aircraft, which are defined by the Defense Advanced Research Projects Agency (DARPA) to have a maximum dimension no greater than 15 cm (approximately 6 in.). A more flexible definition includes aircraft whose flight is characterized by low Reynolds number. 

For attempts to calculate the coupling parameters by quantum-chemical methods, we refer to the literature (Murrell and Pople, 1956 Pople and Sidman, 1957 Liehr, 1957,1958 Albrecht, 1960 Roche and Jaffe, 1974 Merienne-Lafore and Trommsdorff, 1976 Strickler, 1976 Orlandi and Marconi, 1978). The calculations show that the functions d>t(q 0) must not be interpreted literally as adiabatic functions t(q Q) frozen into their configuration for Q = 0 (Johnson and Weigang, 1975 Orlandi, 1976 Siebrand, 1977). To obtain quantitative accuracy in actual calculations, it is necessary to use a more flexible definition of O (q 0) in which some degree of orbital following is permitted. In the same vein one generally defines the vibrational wavefunctions used in the calculation in terms of adiabatic potentials rather than of the crude-adiabatic potentials given by... 

BS 5304 1988 defines a fixed guard as a guard with no moving parts. A more flexible definition could be a guard attached to a machine by a simple fixing method which is not linked to the controls, motion or hazardous condition of a machine since this permits the use of moving parts to provide access for material or utilising a telescopic device. 

One of the most useful applications of solid-state grinding and kneading is undoubtedly the preparation of cocrystals. In the following, we have adopted the liberal view of cocrystal as a multicomponent molecular crystal even though the exact definition of a cocrystal is still matter of debate. The flexible definitions allow us to include solvates and hydrates and also the cases where the difference between salts and neutral systems will depend on the extent of proton transfer along a hydrogen bond. ... 

With respect to standard molecular-cluster techniques, this approach has some attractive features explicit reference is made to the HF LCAO periodic solution for the unperturbed (or perfect) host crystal. In particular, the self-embedding-consistent condition is satisfied, that is, in the absence of defects, the electronic structure in the cluster region coincides with that of the perfect host crystal there is no need to saturate dangling bonds the geometric constraints and the Madelung field of the environment are automatically included. With respect to the supercell technique, this approach does not present the problem of interaction between defects in different supercells, allows a more flexible definition of the cluster subspace, and permits the study of charged defects. The perturbed-cluster approach is implemented in the computer code EMBEDOl [703] and applied in the calculations of the point defects both in the bulk crystal, [704] and on the surface [705]. The difficulties of this approach are connected with the lattice-relaxation calculations. 

J-STD-001 andIPC-A-610 Industry Standards. These consensus industry association standards are widely recognized as the most common standards for requirements and workmanship for PCB assemblies, both nationally and internationally. They allow flexible definition of requirements based on three distinct classes of product, and the acceptability and performance requirements change based upon the contract provisions for the individual product as these classes are appUed.

Electron Correlation. Given the open-shell nature of the ground and excited states of lanthanide impurity ions in crystals, electron correlation is exU cmely important. Currently, electronic structure methods based on the use of multireference wavefunctions appear to be the fittest to respond to the requirements. Furthermore, their current evolution towards allowing more and more flexible definitions of the active space makes them even more adequate. Even though the methods used in the applications contained in this chapter are well known and their performance has been proven and documented in many highly correlated systems, we summarize here how to adapt them to the impurity lanthanide ion electronic structure demands. 

By expanding the fields in terms of finite elements it is possible to determine the spatial distribution of electromagnetic field magnitudes for an arbitrary choice of electric properties subject to an incident plane wave. Since FEM allows a flexible definition of the shape, size and connectivity for finite elements of an arbitrary geometry, the discretization resolution can be improved to any...
