This paper presents a novel technique to increase
the quality of medical images based on Histogram
Equalization. In the proposed method first we have
applied a noise reduction method and then we apply
some suitable preprocessing on histogram of the
medical images and after that histogram equalization
has been applied on the new histogram. Our proposed
method in Despite of its simplicity has better results in
compare to other usual methods based on histogram
equalization. The quality of resulted images after
applying our proposed methods has been tested on a
database (medical images) with a confirmed criterion
by viewer. Also we have considered a mathematical
criterion for comparing our proposed algorithm with
other available methods for contrast enhancement.
Results show the better efficiency of the proposed
method.
The philosophy of the book is to present various pattern recognition tasks in
a unified way, including image analysis, speech processing, and communication applications. Despite their differences, these areas do share common features and their study can only benefit from a unified approach.
G
UILLAIN-BARRéSYNDROME(GBS)is an uncommon disorder,but one
whose impact is far out of proportion to its incidence.Despite a
usually good prognosis,GBS is a particularly frightening and often life-
altering experience for those diagnosed with the disorder.Many patients
are acutely aware of the rapid loss of control of their muscular function,
including vital functions such as breathing and swallowing,and fre-
quently feel that they are dying.The experience is almost as unnerving
for the families of affected individuals.During the acute phase of the ill-
ness GBS patients experience the indignity of helplessness in addition to
their fear of death or permanent disability.Prolonged disability is com-
mon and some permanent residual effects are becoming increasingly
recognized.It has been our experience in meeting patients at support
groups,that individuals who have been affected by GBS have a great
desire for a better understanding of the disorder,even years after the
acute experience.
ieee754的標準,原英文版的!Twenty years ago anarchy threatened floating-point arithmetic. Over a dozen commercially significant arithmetics
boasted diverse wordsizes, precisions, rounding procedures and over/underflow behaviors, and more were in the
works. “Portable” software intended to reconcile that numerical diversity had become unbearably costly to
develop.
Thirteen years ago, when IEEE 754 became official, major microprocessor manufacturers had already adopted it
Despite the challenge it posed to implementors. With unprecedented altruism, hardware designers had risen to its
challenge in the belief that they would ease and encourage a vast burgeoning of numerical software. They did
succeed to a considerable extent. Anyway, rounding anomalies that preoccupied all of us in the 1970s afflict only

During the past two decades there has been a substantial growth in research in
wireless communications. The number of journals published from various parts of
the world catering to the research community has grown exponentially. Despite
such a growth, the engineering community still needs more information so as to
thoroughly comprehend wireless channel characteristics. What specifically must be
understood are the effects of channel degradation brought on by statistical fluctua-
tions in the channel.
This book was conceived in such a special way. From our experience, and Despite the
increasing interest that we perceived amongst the research community in HAPS,
there was not any book in the market entirely devoted to HAPS. We could only find
some satellite communications books including only fragments related to HAPS,
covering the ‘generalities’. A need for a reference book which could highlight state-
of-the-art HAPS-related topics was therefore envisaged. Moreover, most of the
information related to HAPS could only be found in technical reports, official
recommendations, conference proceedings and journal papers.
Digital mobile wireless communication and the Internet have undergone a
fantastic growth in the last few years and, Despite originating from two different
worlds, they are converging. This convergence corresponds to the evolution of
mobile systems towards the highest broadband data transmissions (GSM,
EDGE/GPRS, UMTS then HSDPA), while the computing world gets equipped with
wireless technologies such as Wi-Fi or Wi-Max.
Despite the development of a now vast body of knowledge known as
modern control theory, and Despite some spectacular applications of this
theory to practical situations, it is quite clear that much of the theory has
yet to find application, and many practical control problems have yet to find
a theory which will successfully deal with them. No book of course can
remedy the situation at this time. But the aim of this book is to construct
one of many bridges that are still required for the student and practicing
control engineer between the familiar classical control results and those of
modern control theory.
