Managing inter-object dependencies in object-oriented systems is a complex task. Changes of one
object often require dependent objects to change accordingly. Making every object explicitly inform
every dependent object about its state changes intertwines object interfaces and implementations,
thereby hampering system evolution and maintenance. These problems can be overcome by
introducing the notion of Implicit Invocation to object-oriented systems as a decoupling mechanism
the book’s success is due in no small part to the success of JSP itself.
JavaServer Pages technology has experienced a rapid adoption in the past year or
so, anxiously embraced by the “teeming millions” of Java and web developers who had been clamoring for a standard mechanism for generating dynamic web con-

By means of econometric methods, the information contained in options prices can be
extracted. In the literature, two methods are most frequently chosen, namely the implied
volatility and the risk-neutral density. The latter approach extends the frequently used concept
of the volatility implicit in option prices to modelling the probabilities that market participants
assign to all possible price levels of the underlying instrument. The entire RND offers a wider
information set as it includes the third (skewness) and the fourth (kurtosis) moment of a
With the release of .NET 3.5, the C# language has been enhanced to support a great number of new programming constructs, many of which are used to enable the LINQ API. This chapter, you will learn the role of implicit typing of local variables, partial methods, automatic properties, extension methods, anonymous types, and object initialization syntax.
Reproductive Health (RH) is a state of complete physical, mental and social well-being
(not merely the absence of disease and infirmity) in all matters relating to the reproduc-
tive system and its functions and processes. Reproductive health therefore implies that
people are able to have a satisfying and safe sex life and that they have the capability to
reproduce and the freedom to decide if, when and how often to do so.
Introducing the Microsoft .NET Platform
in use, these objects will always have a reference count greater than zero, so unless they are implicitly deconstructed, their memory may never be recovered. For a C or C++ programmer—accustomed to ensuring that objects are properly destroyed, essentially managing memory on their own—this sounds perfectly normal, and a good reason for not trusting anyone else to take care of managing resources. However, in the .NET environment, Microsoft is striving to make developing software easier. Later in this chapter, we cover a how .
Built-In Database Objects
In addition to creating the database files, several other structures are created.
Data dictionary: Contains descriptions of the objects in the database
Dynamic performance tables: Contains information used by the database administrator (DBA) to monitor and tune the database and instance
PL/SQL packages: Program units adding functionality to the database. These packages are created when the catproc.sql script is run after the CREATE DATABASE command. PL/SQL packages will not be discussed within the scope of this course.
The main objective of this work is to develop efficient techniques to couple solutions
for performance of reservoir and surface facilities, which is a fundamental step
for the development of management routines and for optiinization of total system
Use of conventional techniques for full-field models can be very computation time
intensive and, therefore, such models are either rarely used or they are simplified by
handling surface facilities explicitly.
We present several algorithms for assigning heads in phrase structure trees, based on different linguistic intuitions on the role of heads in natural language syntax. Starting point of our approach is the observation that a head-annotated treebank deﬁnes a unique lexicalized tree substitution grammar. This allows us to go back and forth between the two representations, and deﬁne objective functions for the unsupervised learning of head assignments in terms of features of the implicit lexicalized tree grammars.
This topic will describe the storage of objects in containers, we will focus on linear orderings: Implicitly defined linear orderings (sorted lists), explicitly defined linear orderings. We will summarize this information and look briefly at: Hierarchical orderings, partial orderings, equivalence relations, adjacency relations.
