Table 2: A Synopsis of T1, PD, and T2 E#0Bects on the Magnetic Resonance Image.
1998
"... In PAGE 7: ... In the domain of MRI volumes, there are two primary sources of knowledge available. The #0Crst is pixel intensity in feature space, which describes tissue characteristics within the MR imaging system, which are summarized in Table2 #28based on a review of literature #5B33, 34, 35#5D#29. The second is image#2Fanatomical space and includes expected shapes and placements of certain tissues within the MR image, such as the fact that CSF lies within the ventricles, as shown in Figure 1#28a#29.... In PAGE 13: ... Each MR voxel of interest has a hT 1;PD;T2i location in #3C 3 , forming a feature-space distribution. Based on the knowledge in Table2 , and the fact that pixels belonging to the same tissue type will exhibit similar relaxation behaviors #28T1 and T2#29 and water con- tent #28PD#29, they will then also have approximately the same location in feature space #5B38#5D. Figure 5#28a#29 shows the signal-intensity images of a typical slice, while #28b#29 and #28c#29 show histogram for the bivariate features T1#2FPD and T2#2FPD, respectively, with approximate tissue labels overlaid.... In PAGE 21: ... A region mean, standard deviation, and skewness in hT 1i, hPDi, and hT 2i feature space respectively are used as features. The concept exploited is that trends and characteristics described at a pixel level in Table2 and Section 3.3 are also applicable on a region level.... In PAGE 32: ...The knowledge base was initially built with a general set of heuristics comparing the e#0Bects of di#0Berent pulse sequences on di#0Berenttypes of tissues, as shown in Table2 . This process is called #5Cknowledge-engineering quot; as we had to decide which knowledge was most useful for the goal of tumor segmentation, followed by the process of implementing such information into a rule-based system.... In PAGE 32: ... Thinner slices which exhibit a reduced partial-volume e#0Bect and allow better tissue contrast. While relying on feature space distributions, the system was developed using general tissue character- istics, such as those listed in Table2 , and relative relationships between tissues to avoid dependence upon speci#0Cc feature-domain values. The particular slices were acquired with the same parameters, but gadolinium-enhancement has been found to be generally very robust in di#0Berent protocols and thickness #5B48, 39#5D.... ..."

Table 11 Ratio of water withdrawal to water availability
2000
"... In PAGE 32: ... For the region as a whole, agriculture consumed 81 percent of total water uses in 1990, but with a projected decline in proportion of total consumption to 69 percent by the year 2025 (Table 10). Table11 shows the relationship between water availability and withdrawals at the country level. The island states of Barbados, Cuba, and Dominican Republic as well as Mexico and Peru are particularly vulnerable to water scarcity, with high withdrawals relative to water availability.... ..."
Table 1: Values in magnitude of the source magnetic eld Hs on sample points
"... In PAGE 19: ...ith density Js = 100 A=m2, i.e. total intensity 1 A. To analyse results in di erent space regions, a subdomain is selected: a cylinder with radius R0 = 0:2 m and height H0 = 1 m having the same symmetry axis and the same center as the main domain and the coil winding. Figure 2 shows a planar section of the domain and a selection of sample points located in various positions, chosen for a local evaluation of Hs (see Table1 ). Figure 3 describes qualitatively the perfectly axisymmetric behaviour of the magnetostatic eld generated by the current, computed by Urankar apos;s semi-analytical method, showing the eld streamlines along a planar section containing the symmetry axis.... In PAGE 21: ... In such a case a massive computation of 104-106 nodes can be requested, depending on accuracy requirements on the searched nite element solution. Table1 shows some values of Hs on the selection on eld points shown in Figure 2. Columns 1 through 4 refer to nite volume Gauss-Legendre integration of type (a), using a 4-point rule on each tetrahedral volume, for increasing number of volumes in coils....

As expected, Table1 shows that the numerical results obtained from composite trape- zoidal quadrature of Urankar apos;s one-dimensional integrals (4.3) are closer to values computed by Urankar apos;s semi-analytical method than to values computed by nite volume integra- tion, even in the case of the nest decomposition.... ..."
Table 3. Line emission by cooling gasa
"... In PAGE 6: ... Under equilibrium conditions the ioniza- tion fraction n(X+i)=n(X) is a know function of T and ? can be computed as described in GS90. The values in Table3 are for Tu gt; 4 106 K and solar abundances, lower metallicities give similar results if the relative metals abun- dances are kept constant (GS90). The values of ? are relatively insensitive on the chosen collision strengths because the lines are mostly produced by indirect collisions to high energy states whose apos;s are little in uenced by resonances (Fig.... In PAGE 6: ... 2). The large [Fe XIV]/[Fe X] ratio of Table3 increases further if non{ equilibrium ionization is considered, this delays the recombination of Fe+13 and produces stronger [Fe XIV] (GS90). Collisionally ionized regions are therefore characterized by large [Fe XIV]/[Fe X] ratios and the lower ( lt;1) values found in AGN can only be explained by introducing a temperature cuto at Tu 1:5 106 K, a similar result was already found by Nussbaumer amp; Osterbrock (1970).... ..."

In PAGE 4: ...Table 1: Line cooling; the luminosities are expressed in L Table1 lists all the objects with detected molecular lines for which it was possible to compute the cooling by means of a LVG model (Nisini et al. this vol- ume).... In PAGE 6: ...greement with their position in Fig.3. Some of them also show molecular emission consistent with \C quot; shock models. The luminosity of the FIR lines ranges between 2 and 6 10?4 Lbol (last column in Table1 ), about 10 times less than the value obtained for Class 0/I sources. - High luminosity Class I objects, L gt; 104L : these sources are sur- rounded by relatively large ionised and PDR regions that explain both the relative lack of molecular lines and the presence of intermediate ionisation lines, such as [NIII], [OIII] (Leeks S.... In PAGE 7: ...Table1 ) indicating that non-dissociative \C quot; shock excitation is the dominant physical process, and therefore the [OI] intensity is not expected to be proportional to the mass loss rate. On the line, we nd the following sources, for which dissociative \J quot; shocks should play an important role: - The Herbig-Haro objects: in Liseau et al.... In PAGE 7: ... We also notice that HHs (\J quot; shocks) are the only sources in which we have evidence of shocked gas in beams that do not contain the ow exciting source. - Class 0 and low luminosity Class I sources: the few objects for which molecular line cooling has been computed ( Table1 ) show LCO gt; L[OI] suggesting that in contrast to HH objects, both \J quot; and \C quot; shocks play an important role (see Nisini et al....

A comparison with LCO shows that H2O plays only a minor role in the thermodynamic balance in any of these objects.... ..."
