Exterior

CT offers the opportunity to examine slices through the sample non-destructively and is therefor the only method for measuring exterior and also interior part coordinates without mechanical cutting of the object. 

The changes described above also allowed much easier access to the high voltage cable for routine (6-month) owner directed, service operations, and provided better upper and lower x-ray cabinet and control cabinet ventilation. With the exception of the x-ray tubes, all the individual manufactured components, on all four systems are identical. There are very subtle differences in the warm-up/start-up sequence on the x-ray controllers on the newer systems due to model/year and x-ray tube differences. The last three systems were supplied with environmental type key-boards for the image processors and base-mounted , rather than conduit-mounted exterior warning indicators. The first system was subsequently upgraded to include the better keyboard and the external warning appliances/features. 

Due to the outer circumference of the silo, about 25 meters, a non- or rarely destructive testing method was needed for the localization. Because the building was still in use, it was only accessable from the exterior side. We chose the ultrasonic pulse-echo-technique as an appropriate way of doing the testing. 

Two major sources of ultrasound are employed, namely ultrasonic baths and ultrasonic immersion hom probes [79, 71]- The fonuer consists of fixed-frequency transducers beneath the exterior of the bath unit filled with water in which the electrochemical cell is then fixed. Alternatively, the metal bath is coated and directly employed as electrochemical cell, but m both cases the results strongly depend on the position and design of the set-up. The ultrasonic horn transducer, on the other hand, is a transducer provided with an electrically conducting tip (often Ti6A14V), which is inuuersed in a three-electrode thenuostatted cell to a depth of 1-2 cm directly facing the electrode surface.

Accordingly, the exterior surface is much more reactive than planar analogues, and is comparable to those of electron deficient polyolefins. This, in turn, rationalizes the high reactivity of the fullerene core towards photolytically and radiolytically generated carbon- and heteroatomic-centred radicals and also other neutral or ionic species [8]. The interior, in contrast, is shown to be practically inert [9]. Despite these surface related effects, the... 

Using these procedures it is always possible to generate smooth internal divisions. Therefore they offer the advantage of preventing the extension of the exterior boundary discontinuities to the inside of the problem domain. 

A remarkable feature of the allene NMR spectra is the lowfield position of the central carbon-atom, viz., 185-210 ppm relative to TMS, whereas the exterior carbon-atom resonances are generally found between 60 and 130 ppm. 

Using a multiple linear regression computer program, a set of substituent parameters was calculated for a number of the most commonly occurring groups. The calculated substituent effects allow a prediction of the chemical shifts of the exterior and central carbon atoms of the allene with standard deviations of l.Sand 2.3 ppm, respectively Although most compounds were measured as neat liquids, for a number of compounds duplicatel measurements were obtained in various solvents. 

In describing the chemical shifts of the exterior and central allene carbons, the substituent effect symbols depicted in Fig. 1 were used.

A neutral ligand whose exterior is hydrophobic and whose interior is hydrophilic. 

An agglomeration of molecules containing ionic heads and hydrophobic tails, which form into a structure with a hydrophobic interior and a hydrophilic exterior. 

Here H C is a bounded domain with boundary F, and n is the unit exterior normal to F. The results of this section can be found in (Khludneva, 1990a). 

The above formula for H(x) contains three different terms which correspond to the bending energy of the plate, to the deformation energy of the midsurface, and to the work of the exterior force /, respectively. Also, we introduce the set of admissible displacements... 

The structure of the section is as follows. In Section 2.8.2 we give necessary definitions and construct a Borel measure n which describes the work of the interaction forces, i.e. for a set A c F dr, the value /a(A) characterizes the forces at the set A. The next step is a proof of smoothness of the solution provided the exterior data are regular. In particular, we prove that horizontal displacements W belong to in a neighbourhood of the crack faces. Consequently, the components of the strain and stress tensors belong to the space In this case the measure n is absolutely continuous with respect to the Lebesgue measure. This confirms the existence of a locally integrable function q called a density of the measure n such that... 

A contact between two plates is considered provided that one of the plates has a crack. In a stress free state both plates remain at a given distance from each other. The plate displacements satisfy two restrictions of inequality type. The first restriction describes the nonpenetration between the plates, and it is considered in the exterior of the domain. The second one describes the nonpenetration between crack faces. 

The second plate (which has no cracks) can be in contact with the first plate (which has the crack). We assume that the plates remain at a distance (5 > 0 from each other in the stress free state, 5 = const (see Fig.3.3). They may be in contact due to exterior forces. The mid-surface of the second plate is precisely fl, which corresponds to the negative value of the coordinate By that the first plate is called the upper plate and the second one the lower plate. 

In this subsection we analyse an optimal control problem. The exterior forces f,g) are chosen to minimize the cost functional...

Here n is a unit exterior vector to F. As it was indicated in the previous section, in the domain fig the following problem can be solved.
