Vocabulaire XML
Un vocabulaire (application) XML est une
spcication complte des lments et attributs dun type spcique de documents XML
1. Langue naturelle (petits groupes) 2. Dclarations de type de document (DTD)
(documents publiques)
3. XML Schema
Friday, April 9, 2010
Un autre formalisme ?
<!ENTITY % address "(street, city, province, postal-code)" > <!ELEMENT street (#PCDATA) > <!ELEMENT city (#PCDATA) > <!ELEMENT province (#PCDATA) > <!ELEMENT postal-code (#PCDATA) >
Le DTD est peu expressif Le DTD contraint la structure du
document (ordre et imbrication des lments), mais pas le contenu textuel
Friday, April 9, 2010
Un autre formalisme ?
Le DTD ne supporte pas les espaces de
nommage
Ainsi, si a.dtd importe le contenu de
b.dtd ( laide dune directive), il faut au pralable sassurer que les noms dlments sont uniques
a:name et b:name
Friday, April 9, 2010
Schma XML
Un schma dnit une classe de
documents XML
Un document qui satisfait un schma est
une instance de ce schma
Un Schma XML est un document XML!
Puisque cest un document XML, les espaces de nommage sont supports et lon bnficie de la panoplie doutils XML

<?xml version="1.0" encoding="UTF-8"?> <wine code="00518712" > <rating stars="2"/> <quantity>5</quantity> </wine>
Friday, April 9, 2010
Schma XML
Le formalisme permet la dnition de types! De sorte que lorsquon dnit un lment, par
exemple code-postal, on peut aussi lui associer un type, CodePostal, an de spcier lensemble des valeurs possibles, ici, on sassure que le format est bien [A-Z][0-9][A-Z] [0-9][A-Z][0-9]
Convention : caligraphie semblable aux classes de Java. code-postal lment CodePostal type
Friday, April 9, 2010
Schma XML
Le document WSDL dnit les oprations du
service. Ce faisant, il doit aussi dnir le type des paramtres et des valeurs de retour paramtres et des valeurs de retour
Les messages SOAP encodent les valeurs des Des dnitions formelles (rigoureuses) du
type des valeurs sont absolument ncessaires
Friday, April 9, 2010
Schma XML
Puisque le schma est un vocabulaire
XML, il faudra deux espaces de nommage an de distinguer le schma du vocabulaire quil dnit
Usuellement un chier .xsd XML Schema remplace le DTD comme
formalisme pour la dnition dun vocabulaire
Friday, April 9, 2010
Schma XML
Il y a deux catgories de types: simples
et complexes
Un type simple dnit le contenu
textuel dun lment nayant aucun lment enfant dun lment ayant des lments enfants (donnes structures)
Un type complexe dnit le contenu
Friday, April 9, 2010
Types
zip sera associ un type simple address sera associ un type complexe
<address> <street>800, King Edward</street> <city>Ottawa</city> <zip>K1N 6N5</zip> </address>
Pleusieurs types prdnis : string, int,
boolean, mais aussi date, URI, etc.
Friday, April 9, 2010
Friday, April 9, 2010
Types simples
XML Schema spcie lintervalle de
valeurs ainsi que la reprsentation sous forme de chanes de caractres des types prdnis
Friday, April 9, 2010
Types simples
Les types simples sont associs aux
lments sans enfants
<xs:simpleType> est utilis an de
dnir un nouveau type simple des restrictions
Il faut spcier un type de base ainsi
Friday, April 9, 2010
Types simples

Restrictions (facets)
En plus des restrictions prsentes, on
peut spcier une taille minimale (minLength) ou maximale (maxLength) ainsi que plusieurs autres
Friday, April 9, 2010
Types complexes
Les types complexes sont associs aux
lments ayant des enfants (internes)
<xs:complexType> est utilis an de
dnir un nouveau type complexe
xs:sequence, xs:choice, xs:all

diffrents concepts

11. (a) The vertical components of the individual fields (due to the two charges) cancel, by symmetry. Using d = 3.00 m and y = 4.00 m, the horizontal components (both pointing to the x direction) add to give a magnitude ofEx ,net = 2|q|d 2(8.99 109 N m

17. We make the assumption that bead 2 is in the lower half of the circle, partly because it would be awkward for bead 1 to slide through bead 2 if it were in the path of bead 1 (which is the upper half of the circle) and partly to eliminate a second solu

18. According to the problem statement, Eact is Eq. 22-5 (with z = 5d)Eact = q q 160 q = 2 2 4 0 (4.5d ) 4 0 (5.5d ) 9801 4 0 d 2and Eapprox isEapprox =2qd 2 q = . 3 4 0 (5d ) 125 4 0 d 2The ratio isEapprox Eact = 0.9801 0.98.

20. Referring to Eq. 22-6, we use the binomial expansion (see Appendix E) but keeping higher order terms than are shown in Eq. 22-7:E=q d 3 d2 1 d3 d 3 d2 1 d3 + 4 z2 + 2 z3 + 1 z + 4 z2 2 z3 + 2 1 + z 4o z q d3 qd + + = 2o z3 4o z5Therefore, in the t

21. Think of the quadrupole as composed of two dipoles, each with dipole moment of magnitude p = qd. The moments point in opposite directions and produce fields in opposite directions at points on the quadrupole axis. Consider the point P on the axis, a d
The Petroleum Institute - PHYS - 344
23. We use Eq. 22-3, assuming both charges are positive. At P, we haveEleft ring = Eright ring 4 0 ( R + R2q1 R2 3/ 2)=q2 (2 R) 4 0 [(2 R ) 2 + R 2 ]3/ 2Simplifying, we obtainq1 2 = 2 q2 53/ 2 0.506.
The Petroleum Institute - PHYS - 344
25. From symmetry, we see that the net field at P is twice the field caused by the upper semicircular charge + q = R (and that it points downward). Adapting the steps leading to Eq. 22-21, we findj Enet = 2 () sin 4 0 R9090 q j. = 2 2 0 R (a) With

28. We use Eq. 22-16, with q denoting the charge on the larger ring:qz qz 13 + = 0 q = Q 2 2 3/ 2 2 2 3/ 2 4 0 ( z + R ) 4 0 [ z + (3R) ] 53/ 2= 4.19Q .Note: we set z = 2R in the above calculation.

30. (a) It is clear from symmetry (also from Eq. 22-16) that the field vanishes at the center. (b) The result (E = 0) for points infinitely far away can be reasoned directly from Eq. 2216 (it goes as 1/z as z ) or by recalling the starting point of its de

31. First, we need a formula for the field due to the arc. We use the notation for the charge density, = Q/L. Sample Problem 22-3 illustrates the simplest approach to circular arc field problems. Following the steps leading to Eq. 22-21, we see that the g

33. Consider an infinitesimal section of the rod of length dx, a distance x from the left end, as shown in the following diagram. It contains charge dq = dx and is a distance r from P. The magnitude of the field it produces at P is given by dE = 1 dx . 4

The Petroleum Institute - PHYS - 344
36. We write Eq. 22-26 as E z = 1 2 Emax ( z + R 2 )1/ 2 and note that this ratio is 2 (according to the graph shown in the figure) when z = 4.0 cm. Solving this for R we obtain R = z 3 = 6.9 cm.1
