As digital libraries and the World Wide Web (WWW) continue to grow exponentially,
the ability to find useful information will greatly depend on the associated
underlying framework of the indexing infrastructure or search engine. The push to
get information on-line must be mediated by the design of automated techniques for
extracting that information for a variety of users and needs. What algorithms and
software environments are plausible for achieving both accuracy and speed in text
An open problem in dependency parsing is the accurate and efﬁcient treatment of non-projective structures. We propose to attack this problem using chart-parsing algorithms developed for mildly contextsensitive grammar formalisms. In this paper, we provide two key tools for this approach. First, we show how to reduce nonprojective dependency parsing to parsing with Linear Context-Free Rewriting Systems (LCFRS), by presenting a technique for extracting LCFRS from dependency treebanks.
Learning objectives: To learn about data flow diagrams (DFDs) and the symbols used in them, to understand a context diagram and its decomposition, to understand the standard symbols used in flow charts.

The invariable motif for analog design is to explore the new circuit topologies, architectures and CAD technologies to overcome the design challenges coming from the new applications and new fabrication technologies. In this book, a new architecture for a SAR ADC is proposed to eliminate the process mismatches and minimize the errors.
This section illustrates some general concepts of artificial neural networks, their
properties, mode of training, static training (feedforward) and dynamic training
(recurrent), training data classification, supervised, semi-supervised and unsupervised
training. Prof. Belic Igor’s chapter that deals with ANN application in modeling,
illustrating two properties of ANN: universality and optimization. Prof.
Multi-carrier modulation, in particular Orthogonal Frequency Division
Multiplexing (OFDM), has been successfully applied to a wide variety of
digital communications applications over the past several years. Although
OFDM has been chosen as the physical layer standard for a diversity of
important systems, the theory, algorithms, and implementation techniques
remain subjects of current interest. This is clear from the high volume of
papers appearing in technical journals and conferences.
Within a sketch you can create 2D-wireframe geometry which can be used to produce
Solids or surfaces and is represented by a solid line font. 2D-construction wireframe
geometry can also be created which is used as an aid to produce the solid 2Dwireframe
geometry. To position and control the size of the sketch, geometric and
positional constraints are used which are displayed in green. A Sketch Node will be
attached to the Specification Tree in which the Sketch Axis, Geometry and
Constraints details are held.
Marketers have identified urban, low-income African-American and Latino youth as
“superconsumers” of soda, candy, and snack products. Many young people report frequent
snacking, unstructured meals, and eating “junk food,” such as candy, chips, and soda, for their
primary meal. Recent research studying the amount and type of advertising on prime-time
television programs oriented to African-American audiences compared to those for general
audiences found that far more food commercials appear on shows with large...
Orthogonal frequency division multiplexing (OFDM) is becoming the chosen
modulation technique for wireless communications. OFDM can provide large data
rates with sufficient robustness to radio channel impairments. Many research centers
in the world have specialized teams working in the optimization of OFDM for
countless applications. Here, at the Georgia Institute of Technology, one of such
teams is in Dr. M. A. Ingram’s Smart Antenna Research Laboratory (SARL), a part
of the Georgia Center for Advanced Telecommunications Technology (GCATT).
Model in general sense is an analogue of the object under consideration, which
replaces this object in human cognition. If the replacement action happens consciously,
we call it Modelling. Science works by building models. Not cardboard or plasticine
models, but models made out of symbols, special terms, theories, axioms, theorems
etc. This helps to formulate ideas and identify underlying assumptions in formalized
and abstracted form.
Cross drawings are as old as time. They have been around even before Christ and Christianity. The cross symbolizes life, immortality,union of the heavens and earth and the sun and stars. It's no wonder so many people select this image as a tattoo. It is arguably the most widely used image in both ancient and modern tattoos. Throughout history each culture has reinvented and redesigned this sacred image leaving us with many different versions. There are many variations of cross drawings which I will display below. Again as with tattoos and other drawings, personal taste and style rules all....
Our contribution in this area is the creation of lightweight techniques for securing existing sensor network
routing and data movement approaches, such as directed diffusion , spin  and data dissemination [9, 2]. We
assume the computational capability and memory requirements typical of those provided by current generation of
sensors. We note that in this work we make no attempt to counter the threat from a widespread denial of service
attack against the RF layer.
Drawings of roses can represent quite a lot in a tattoo. While tattoos are usually very personal, there are a few recurring themes or symbols that are universal. Rose drawings in Western culture are the symbol of pure love, much like lotus drawings are in the East. The specific color of the rose, like most flowers, will change its meaning; however, in most tattoos you will see the rose depicted as red. While I am not a professional tattoo artist and can only speculate at best why a specific color or image is used in each tattoo, I can...
This book is the second volume by the author on Prolog programming and its applications written for Ventus.
Whereas in the first book , specific Prolog programming techniques were explained, in this volume we discuss
some areas where Prolog can be fruitfully employed.
Both books owe their existence to the recognition that the higher educational system (in the UK) does not
offer enough opportunities for students to experience the satisfaction associated with successfully completing
a technical task.
Any message written over a fixed set of symbols can be represented as a binary string (a sequence of 0's and 1's)
Binary digits 0 and 1 are called bits
To reduce computation overhead, encryption algorithms should only use operations that are easy to implement
For a binary string X:
The length of X, denoted by |X|, is the number of bits in X
If |X| = l, X is an l-bit binary string
Let a be a binary bit and k a non-negative integer. Denote by ak a binary string consisting of k copies of a
Denote the concatenation of X and Y by XY or...
Jane Eyre is always not only one of the most prominent novels in Victorian age
but also ranked among the top masterpieces in the literature history of human. The work
has been loved by thousands of readers from generation to generation, from every
corner in the world. Symbolic characters, writing techniques, simple and realistic plot,
universal theme, etc, in which the bright talent of the female author - Charlotte Bronte
do become great important factors contributing the success of the work.
Machine control design is a unique area of engineering that requires the knowledge
of certain specific and unique diagramming techniques called ladder diagramming.
Although there are similarities between control diagrams and electronic diagrams, many
of the component symbols and layout formats are different. This chapter provides a study
of the fundamentals of developing, drawing and understanding ladder diagrams.
THE TECHNIQUES described in this book assume you have a reasonable working knowledge of Flash. In later chapters, we’ll discuss ways of working that involve symbols, timelines and various animation techniques.
This first chapter will serve as a refresher course on the fundamentals of designing for animation and introduce a few cool drawing techniques along the way.
