The past few years have seen a major change in computing systems,
as growing data volumes and stalling processor speeds require more
and more applications to scale out to clusters. Today, a myriad
data sources, from the Internet to business operations to
scientific instruments, produce large and valuable data streams.
However, the processing capabilities of single machines have not
kept up with the size of data. As a result, organizations
increasingly need to scale out their computations over clusters. At
the same time, the speed and sophistication required of data
processing have grown. In addition to simple queries, complex
algorithms like machine learning and graph analysis are becoming
common. And in addition to batch processing, streaming analysis of
real-time data is required to let organizations take timely action.
Future computing platforms will need to not only scale out
traditional workloads, but support these new applications too. This
book, a revised version of the 2014 ACM Dissertation Award winning
dissertation, proposes an architecture for cluster computing
systems that can tackle emerging data processing workloads at
scale. Whereas early cluster computing systems, like MapReduce,
handled batch processing, our architecture also enables streaming
and interactive queries, while keeping MapReduce's scalability and
fault tolerance. And whereas most deployed systems only support
simple one-pass computations (e.g., SQL queries), ours also extends
to the multi-pass algorithms required for complex analytics like
machine learning. Finally, unlike the specialized systems proposed
for some of these workloads, our architecture allows these
computations to be combined, enabling rich new applications that
intermix, for example, streaming and batch processing. We achieve
these results through a simple extension to MapReduce that adds
primitives for data sharing, called Resilient Distributed Datasets
(RDDs). We show that this is enough to capture a wide range of
workloads. We implement RDDs in the open source Spark system, which
we evaluate using synthetic and real workloads. Spark matches or
exceeds the performance of specialized systems in many domains,
while offering stronger fault tolerance properties and allowing
these workloads to be combined. Finally, we examine the generality
of RDDs from both a theoretical modeling perspective and a systems
perspective. This version of the dissertation makes corrections
throughout the text and adds a new section on the evolution of
Apache Spark in industry since 2014. In addition, editing,
formatting, and links for the references have been added.
Wearable continuous monitoring systems are necessary in risky
environments such as mining and diving and are especially important
in the medical monitoring of patients both in medical facilities
and at home. All these applications of monitoring with data
transmission functions can be achieved by using wearable antennas.
Recently, possibilities of connecting completely independent
appliances with textiles have emerged. However, full success will
be achieved only when antennas and all related components are
entirely converted into 100% textile materials. Design and
Optimization of Sensors and Antennas for Wearable Devices provides
innovative insights on the development of adaptable materials and
textile antennas that can be used in the construction of wearable
devices that are biocompatible and offer high conductivity, low
cost, simplistic manufacturing, are comfortable for the wearer, and
are water/climate safe and condition amicable. The content within
this publication examines data transmission, wearable computing,
and medical applications. It is designed for engineers,
manufacturers, researchers, academicians, and scientists who are
interested in the development of wearable technologies.
Recent years have witnessed the rise of analysis of real-world

who intend to learn HP-UX from the beginning. This book contains 33
chapters. The book is organized in such a way that it helps its
audience understand concepts, implementation procedures, some basic
troubleshooting, command syntax, configuration files, and daemons
involved. There are three key areas: UNIX fundamentals, HP-UX
system administration, and HP-UX network administration. 1.UNIX
Fundamentals covers the basics of UNIX. Most information is not
specific to a particular UNIX flavor, but rather includes general
UNIX concepts, file manipulation and security techniques, shell and
awk programming, vi editor, basic commands, and other topics.
Chapters 01 through 06 and chapter 21 cover this area. Unlike many
other similar books, a chapter on shell scripting is presented
after covering HP-UX System Administration chapters. This is done
intentionally to provide readers with some practical examples based
on the knowledge they have gained from UNIX Fundamentals and HP-UX
System Administration chapters. 2.HP-UX System Administration
covers the HP-UX-specific system administration concepts and topics
including HP-UX installation methods; software and patch
management; user and group account administration; disk and device
file management; LVM and file system administration; swap space and
printer management; system startup and shutdown procedures; kernel
reconfiguration techniques; backup, restore, and system recovery
functions; job automation and process control; system logging and
performance monitoring; and so on. Chapters 07 through 20 cover
this area. 3.HP-UX Network Administration covers HP-UX network
administration concepts and topics such as OSI and TCP/IP models;
network hardware overview; LAN card administration; IP subnetting
and routing techniques; network troubleshooting tools; system
startup services; naming services such as DNS, NIS, and LDAP; File
sharing tools viz. NFS and AutoFS; Time synchronization using NTP;
internet services administration; BootP/TFTP services; system
security; and so on. Chapters 22 through 33 cover this area. The
beginning of each chapter highlights objectives covered. The end of
each chapter includes a summary as to what is learnt in the
chapter. Throughout the book tables, figures, screen shots, and
examples are given to explain concepts and tasks. The output
generated as a result of running commands is highlighted in light
grey background to differentiate it with surrounding text. The book
includes several appendices one of which contains more than 550
practice exam questions. Tables of commands, important files, and
service daemons are included in separate appendices.
