Future broadband wireless communication systems are expected to be
able to offer new and powerful services enabling fast transmission
rates of several tens of Mbit/s. This is an ambitious challenge
especially for mobile communication systems since these systems
should be able to cope with severely time dispersive channels,
associated to the signal multipath propagation. Moreover, these
systems should have high spectral and power efficiencies, as well
as high capacity and flexibility. Spread spectrum techniques,
particularly coded division multiple access (CDMA) techniques allow
high capacity and flexibility, continuous transmission requiring
low-peak power requirements for the amplifiers, as well as some
robustness against fading and time-dispersion effects associated
with the multipath propagation. When employed in prefix assisted
(PA) block transmission schemes combined with frequency-domain
receiver implementations they become especially interesting for
broadband wireless systems. In Frequency-Domain Multiuser Detection
for CDMA Systems the use of PA block transmission is considered in
the context of both DS (Direct Sequence) and MC (Multicarrier) CDMA
schemes. The main goal is the study of frequency-domain multiuser
detection techniques with iterative signal detection/decoding
techniques, also in combination with estimation and cancelation of
nonlinear distortion effects. The receiver structures are suitable
to scenarios with high interference levels and strongly
time-dispersive channels.
High-Resolution IF-to-Baseband SigmaDelta ADC for Car Radios
addresses the theory, system level design and circuit
implementation of a high-resolution continuous-time IF-to-baseband
quadrature SigmaDelta ADC. The target application of this ADC is in
AM/FM/IBOC car radios. The ADC achieves a dynamic range of 118dB,
which eliminates the need for an IF VGA or AM channel filter in car
radios. The author is very well known within the Analog Circuits
community.

This book provides a selection of the best papers presented at the
18th Conference of the Portuguese Association for Information
Systems (CAPSI), which was held in 2018. The focus of the
conference and of these proceedings lies on the interplay between
information systems and Industry 4.0. All contributions, which
include original research, review papers and case studies, were
peer-reviewed in a double blind process.
One of the most important issues businesses face is how to adapt to
changing operational and administrative processes. Globalization
and high competition highlight the importance of technological
innovation and its contribution to the organizational performance
of businesses. Technological Developments in Industry 4.0 for
Business Applications is a collection of innovative research on the
methods and applications of developing new services related to
industrial processes in order to improve organizational well-being.
It also looks at the technological, organizational, and social
aspects of Industry 4.0. Highlighting a range of topics including
enterprise integration, logistic models, and supply chain, this
book is ideally designed for computer engineers, managers, business
and IT professionals, business researchers, and post-graduate
students seeking current research on the evolution and development
of business applications in the modern industry era.

The electronic storage of medical patient data is becoming a daily
experience in most of the practices and hospitals worldwide.
However, much of the available data is in free text form, a
convenient way of expressing concepts and events but especially
challenging if one wants to perform automatic searches,
summarization or statistical analyses. Information Extraction can
relieve some of these problems by offering a semantically informed
interpretation and abstraction of the texts. MedInX, the Medical
Information eXtraction system presented in this book is designed to
process textual clinical discharge records in order to perform
automatic and accurate mapping of free text reports onto a
structured representation. MedInX components are based on Natural
Language Processing principles, and provide several mechanisms to
read, process and utilize external resources, such as terminologies
and ontologies. MedInX current practical applications include
automatic code assignment and an audit system capable of
systematically analyze the content and completeness of the clinical
reports.
Las Cronicas de Nanko, narra las aventuras de un guerrero conocido
como Nanko entre los suyos. Se trata de un joven de 16 anos que
viaja a un mundo paralelo donde las leyendas de barbaros, brujos y
otros monstruos toman vida. En el mundo paralelo el joven asume la
personalidad del guerrero Nanko y la unica manera de que pueda
regresa a su epoca sera uniendo fuerzas con otros guerreros y
tratar de derrocar a un malvado brujo. Las cosas no se pondran
faciles para Nanko y sus aliados pero deberan llenarse de valor
para poder alcanzar la vitoria. El autor ha tratado de que sus
lectores no tengan ni un segundo para respirar, llenando esta
novela con mucha adrenalina, momentos de suspense y sobre todo se
ha esforzado para que fuera un libro bastante dinamico.

CP violation is an intriguing and elusive subject, and current
knowledge of it remains limited, on both the experimental and
theoretical levels. Researchers lack a fundamental understanding of
its origin, and this is all the more important because CP violation
is related to the generation problem and mass problem, two of the
basic open questions in particle physics. This book provides
beginning researchers with a self-contained introduction to the
subject, starting at an elementary level and taking the reader to
the forefront of current research.
