Linear shape described

PicArsn, Dover, N J, jointly with Emtex Division,Missile Systems of Texas, is an improvement over previous models of snakes described briefly in Vol 2, pp B17-R B18-L. The kit is built in five-foot sections and measures over 400 ft long when fully extended. It is towed to the edge of a known minefield, pushed the rest of the way in, then detonated by machine gun fire. The concussion of the linear-shaped chge sets off any mines in the area, thus clearing a safe path for vehicles and troops (Refs 9,11,12 13, P 11T)... [Pg.483]

It is shown by substitution that this equation is satisfied by the straight line, y = mx + c, with first and second derivatives Sly = m, S/2y = 0. A string which is stretched between two points is known to assume this linear shape. Such a string, when disturbed, goes into harmonic vibration with displacements described by sine functions,... [Pg.42]

The hybridisation between one s orbital and one p orbital results in two sp hybrid orbitals, which form a linear shape. In this scenario, the second and third p orbitals are left unhybridised, and are orthogonal to each other, but co-linear with the axis described by the sp orbitals. Examples of this geometry include BeCl2, RC=N, RC=CR and R-N+=C. They all have in common that there are two... [Pg.77]

It should be added that the non-linear shape of log Vs = f(l/T) diagram (curve A, Fig. 1) in the temperature region proceeding the melting point of n-octadecanol is the result of the 7 — q polymorphic transition in the solid alcohol. Abrahamsson et al [27] and Tanaka et al [28] described precisely the 7 and a structures. [Pg.507]

As these functions are clearly determined in each coordinate system we describe them as components of geometrical (or physical) objects. If these components are given in a coordinate system, they are determined in all other coordinate systems by a simple linear transformation law. Because of the special linear shape of these transformation laws this geometrical object is called a tensor, more precisely, the fundamental tensor of the Riemannian space. [Pg.321]

For this attribute of shape, described by the counts of one-bond fragments, P, Kier selected for P ax the complete graph, where all atoms are bonded to each other. For any number of atoms, A, the value of P ax = ( 1W2. For the P in structure he has selected the linear graph where the value is P ax- Table 6, entry no. 1 is the graph of where A = 5. Entry no. 2 is the graph of Pmin where A = 5. [Pg.203]

The initial condition used for all calculations was a linear shape for k. This was a convenient shape, and for later times in the computations, the results are rather insensitive to the initial conditions. This problem is readily solved using numerical methods described in references [57]. [Pg.243]

Comparison of the approximate relation (5.61) with the numerical solution of the full system of equations (5.32), (5.18), (5.35), (5.36), (5.38) and (5.58) is given in Figure 5.5. Parameters for the calculations are displayed in Table 5.1 the respective dimensionless parameters are listed in Table 5.2. We see that the linear shape (5.61) describes the numerical temperature profile quite well. Local currents calculated with the relation (5.31) using the numerical and analytical temperature shapes agree even better (Figure 5.6). [Pg.208]

Albeit some of the linear oligomers described in Sect. 2 also have branched molecular shape, all of them have a ID conjugation backbone that allows them to be considered as linear conjugated oligomers. This section will concentrate on oligomers having several conjugated units connected to three- or four-functional... [Pg.59]

At small cell currents, transport losses are negligible, Rorr is constant along x and the solution to Equation 1.80 describes the linear shape... [Pg.51]

The quadrupole ion trap mass analyzer operates by similar principles as the linear quadrupole described above and is a common mass analyzer found in GC-MS instruments. The ion trap consists of two hyperbolic endcap electrodes and a doughnut-shaped ring electrode (the endcap... [Pg.121]

A basis set is a set of functions used to describe the shape of the orbitals in an atom. Molecular orbitals and entire wave functions are created by taking linear combinations of basis functions and angular functions. Most semiempirical methods use a predehned basis set. When ah initio or density functional theory calculations are done, a basis set must be specihed. Although it is possible to create a basis set from scratch, most calculations are done using existing basis sets. The type of calculation performed and basis set chosen are the two biggest factors in determining the accuracy of results. This chapter discusses these standard basis sets and how to choose an appropriate one. [Pg.78]

When we draw a scatter plot of all X versus Y data, we see that some sort of shape can be described by the data points. From the scatter plot we can take a basic guess as to which type of curve will best describe the X—Y relationship. To aid in the decision process, it is helpful to obtain scatter plots of transformed variables. For example, if a scatter plot of log Y versus X shows a linear relationship, the equation has the form of number 6 above, while if log Y versus log X shows a linear relationship, the equation has the form of number 7. To facilitate this we frequently employ special graph paper for which one or both scales are calibrated logarithmically. These are referred to as semilog or log-log graph paper, respectively. [Pg.207]

The above discussion points out the difficulty associated with using the linear dimensions of a molecule as a measure of its size It is not the molecule alone that determines its dimensions, but also the shape in which it exists. Linear arrangements of the sort described above exist in polymer crystals, at least for some distance, although not over the full length of the chain. We shall take up the structure of polymer crystals in Chap. 4. In the solution and bulk states, many polymers exist in the coiled form we have also described. Still other structures are important, notably the helix, which we shall discuss in Sec. 1.11. The overall shape assumed by a polymer molecule is greatly affected... [Pg.6]

The nonpenetration condition is imposed both in the domain and on T. Thus, let the equation 2 = (a ,y) describe the punch shape, (a , y) G fl, G C°°(fi). Then the nonpenetration condition for the plate-punch system in a linear approach takes the form... [Pg.149]

E is an error matrix taking errors of measurement (e. g. random noise) into consideration. The term component describes such chemical or physical states the spectra of which cannot be generated by a linear combination of the other components. Thus, components can be elements, chemical compounds - stoichiometric or non-stoichiometric - or even states induced by physical processes, provided that the spectra differ significantly, e. g. in line shapes or line shifts. [Pg.20]

Both Flory [143] and Huggins [144] in 1941 addressed themselves to this problem with the initial aim of describing solutions of linear polymers in low molecular weight solvents. Both used lattice models, and their initial derivations considered only polymer length (rather than shape, i.e. branching, etc.) The derivation given here will also limit itself to differences in molecular size, but will be based on an available volume approach. [Pg.58]

Liquids are able to flow. Complicated stream patterns arise, dependent on geometric shape of the surrounding of the liquid and of the initial conditions. Physicists tend to simplify things by considering well-defined situations. What could be the simplest configurations where flow occurs Suppose we had two parallel plates and a liquid drop squeezed in between. Let us keep the lower plate at rest and move the upper plate at constant velocity in a parallel direction, so that the plate separation distance keeps constant. Near each of the plates, the velocities of the liquid and the plate are equal due to the friction between plate and liquid. Hence a velocity field that describes the stream builds up, (Fig. 15). In the simplest case the velocity is linear in the spatial coordinate perpendicular to the plates. It is a shear flow, as different planes of liquid slide over each other. This is true for a simple as well as for a complex fluid. But what will happen to the mesoscopic structure of a complex fluid How is it affected Is it destroyed or can it even be built up For a review of theories and experiments, see Ref. 122. Let us look into some recent works. [Pg.766]
