Note that these comparisons are fairly subjective, and your answers will reflect your experience of the different freight modes in your industry, product type and geographic location.

ReVelle (2001, p. 459) defines location analysis as "the development of formulations and algorithms/methodologies to site facilities of diverse kinds in a spatial or geographic environment". In the following, the facilities to be located are further specified to possess point characteristics excluding models dealing with the location of area objects. The latter are employed to support facility layout and hence are not relevant in the context of this work (cf. Domschke and Krispin (1997) or Francis et al. (1992) for further references on facility layout models).

In order to compare the PMMA results with those obtained with the carboxylic acrylic latex, the concentration of surface carboxyls must be determined. Acid location analysis (5 was carried out for this purpose. Briefly, the latexes were titrated conductometrically with 0.1N NaOH followed by a titration of the aqueous phase from which the particles had been removed by centrifugation. The difference in the two titrations provided the distribution between surface and soluble acid. The deficit between the total acid thus determined and the concentration of acrylic acid used in the polymerization was termed "buried". Although some drift occurred in the conductance with time, an equilibration time of approximately 10 minutes per addition of sodium hydroxide was generally sufficient to yield stable readings.

A growing body of data on Antarctic ice cores shows that the history of volcanic eruptions is resolvable year-by-year (38). The record includes dated explosive events such as Cerro Hudson in 1991, Pinatubo-1991, Agung-1963, Krakatoa-1883, Tambora-1815, and a 1259 AD eruption of unknown location. Analysis of the oxygen and sulfur isotope composition of aerosol particles frozen in the polar refrigerator provides a proxy of atmospheric chemistry applicable to early Earth. Aerosols from Cerro Hudson, the smallest of the explosive eruptions, have normal sulfur isotope compositions with no anomalous fractionation of (39). Cerro Hudson s eruption cloud did not break... 

One site location which should never be overlooked is that of present company-owned sites where new facilities can be added to present facilities at possibly lower costs. This type of site is subject to the same site location analysis as new sites it is almost always included in the final economic comparison submitted to management (see Table 7-3). 

A recommended proceduVe, which will be illustrated by an example in this chapter, involves a relative evaluation of the primary factors of raw materials and markets. This will serve to eliminate certain regions from the plant location analysis. For example, if neither the raw materials nor markets are located in the Rocky Mountain region, it would be foolish to set up a large tonnage operation in this region. The next step is to...

Since the moment tensor is a symmetric tensor of the 2" rank, the number of independent components is six as mn, m, m, m22, m2s, and mss. These components can be determined from the observation of the first motions at more than six sensor locations. To solve Eq. 8.10, the coefiBcient Cs, the reflection coefficient i e(t,r), the distance R, and its direction cosine vector r are necessary. The determination of Cs and i e(t,r) is discussed in the previous sections. Other values can be obtained from the source (flaw) location analysis. Thus, the location analysis is essential to perform the moment tensor analysis. 

One result which was analyzed in a hydro-fracturing test is shown in Fig. 8.10. Eight AE events are analyzed and plotted in the elevation view. AE events are plotted at their locations from the location analysis. Then, cracks are classified based on the shear ratio. Tensile crack are indicated by arrow s3Tnbols, of which directions are determined from the direction el. Shear cracks are represented by cross symbols, of which two directions correspond to the two vectors 1 and n. Only the event No. 14 was classified into the mixed-mode cracking, and both orientations of the tensile and the shear are indicated. Results are so successful that AE events are located along the dip plane presumed from the dip angle. Remarkably, the directions of crack opening of the tensile cracks are vertical to, and the orientations of the shear cracks seem parallel to the dip plane. 

Modem AE research in concrete was started in the 1970 s. Wells studied AE waveforms, finding the relationship between strain measurement and AE events (Wells 1970). Studies on fundamentals of AE activity and the effects of mixture proportion were conducted (McCabe et al. 1976 Nielsen and Griffith 1977 Mlakar, Walker et al. 1984). A frequency analysis and a source location analysis were also reported (Fetis 1976 Niwa, Kobayashi et al. 1978 Reymond, Raharinaivo et al. 1983 Berthelot and Robert 1987 Weiler, Xu et al. 1997). In due course, applications to reinforced concrete strictures were investigated (Niwa, Kobayashi et al. 1977 Kobayashi, Hawkins et al. 1980). These studies have resulted in practical applications to monitor micro-cracks in concrete stmctures and going to be made practical as diagnostic applications (Ohtsu 1988).

The majority of all work carried out to date makes use of arrival time analysis, and subsequently a wave velocity value for thickness measurement and for defect location. The wave velocity in a composite material is difficult to use precisely because of the anisotropic characteristics of a composite material. A typical wave or phase velocity profile in polar coordinates is illustrated in Figure 8, showing the nonspherical nature of the wave velocity distribution. The wave velocity distribution can even be more complex for a realistic composite material structure. Despite a possible weakness in the understanding of basic physics and wave propagation in a composite material, thickness measurement can still be carried out by using carefully selected calibration specimens and procedures. Calibration of a test instrument can therefore be carried out for subsequent thickness measurement and defect location analysis in a structure. 

Electron paramagnetic resonance (EPR) spectroscopy (also called electron spin resonance (ESR) spectroscopy), is used to study paramagnetic species with one or more unpaired electrons, e.g. free radicals, diradicals, metal complexes containing paramagnetic metal centres, defects in semiconductors and irradiation effects in solids. While diamagnetic materials are EPR silent, paramagnetic species always exhibit an EPR spectrum. This consists of one or more lines, depending on the interactions between the unpaired electron (which acts as a probe ) and the molecular framework in which it is located. Analysis of the shape of the EPR spectrum (the number and positions of EPR lines, their intensities and line widths) provides information...
