A flood of data means that many of the challenges in biology are
now challenges in computing. Bioinformatics, the application of
computational techniques to analyse the information associated with
biomolecules on a large-scale, has now firmly established itself as
a discipline in molecular biology, and encompasses a wide range of
subject areas from structural biology, genomics to gene expression
studies. In this text we provide an introduction and overview of
the current state of the field. We discuss the main principles that
underpin bioinformatics analyses, look at the types of biological
information and databases that are commonly used, and finally
examine some of the studies that are being conducted, particularly
with reference to transcription regulatory systems. The aims of
bioinformatics are threefold. First, at its simplest bioinformatics
organises data in a way that allows researchers to access existing
information and to submit new entries as they are produced, e.g.
the Protein Data Bank for 3D macromolecular structures . While
data-curation is an essential task, the information stored in these
databases is essentially useless until analysed. Thus the purpose
of bioinformatics extends much further. The second aim is to
develop tools and resources that aid in the analysis of data. For
example, having sequenced a particular protein, it is of interest
to compare it with previously characterised sequences. This needs
more than just a simple text-based search and programs such as
FASTA and PSI-BLAST must consider what comprises a biologically
significant match. Development of such resources dictates expertise
in computational theory as well as a thorough understanding of
biology. The third aim is to use these tools to analyse the data
and interpret the results in a biologically meaningful manner.
Traditionally, biological studies examined individual systems in
detail, and frequently compared them with a few that are related.
In bioinformatics, we can now conduct global analyses of all the
available data with the aim of uncovering common principles that
apply across many systems and highlight novel feature.
Gain insight into how to govern and consume IBM's unique in-motion
and at-rest Big Data analytic capabilitiesA. R. Ammons once said,
"A word too much repeated falls out of being", and although the
term Big Data sometimes seems to be "too much repeated", it's not
about to fall "out of being". That said, it is subject to a lot of
hype. The term Big Data is a bit of a misnomer. Truth be told,
we're not even big fans of the term--despite the fact that it is so
prominently displayed on the cover of this book--because it implies
that other data is somehow small (it might be) or that this
particular type of data is large in size (it can be, but doesn't
have to be). This is Big Data in a nutshell: It is the ability to
retain, process, and understand data like never before. It can mean
more data than what you are using today; but it can also mean
different kinds of data, a venture into the unstructured world
where most of today's data resides. The Big Data opportunity. It's
a shift, rift, lift, or cliff for your business--this book is going
to help you experience the shift and lift, while those that don't
work to get beyond the hype end up in a rift or cliff. In this book
you will learn how cognitive computing systems, like IBM Watson,
fit into the Big Data world. You'll learn how Big Data needs a
"ground-to-cloud" architecture, what a Data Refinery looks like,
and theimportance of a next generation data platform. Gain an
understanding of the concepts of data-in-motion, data-at-rest
(technologies like Hadoop play here, as well as others), the role
that NoSQL and polyglot play in a leading edge analytics
architecture, and more. Get details about the Big Data platform
manifesto and why it is a must for any Big Data project. Capturing,
storing, refining, transforming, governing, securing, and analyzing
data, traditionally or as a service, are important topics
alsocovered in this book.
Modern vehicles have electronic control units (ECUs) to control
various subsystems such as the engine, brakes, steering, air
conditioning, and infotainment. These ECUs (or simply
'controllers') are networked together to share information, and
output directly measured and calculated data to each other. This
in-vehicle network is a data goldmine for improved maintenance,
measuring vehicle performance and its subsystems, fleet management,
warranty and legal issues, reliability, durability, and accident
reconstruction. The focus of Data Acquisition from HD Vehicles
Using J1939 CAN Bus is to guide the reader on how to acquire and
correctly interpret data from the in-vehicle network of heavy-duty
(HD) vehicles. The reader will learn how to convert messages to
scaled engineering parameters, and how to determine the available
parameters on HD vehicles, along with their accuracy and update
rate. Written by two specialists in this field, Richard (Rick) P.
Walter and Eric P. Walter, principals at HEM Data, located in the
United States, the book provides a unique road map for the data
acquisition user. The authors give a clear and concise description
of the CAN protocol plus a review of all 19 parts of the SAE
International J1939 standard family. Pertinent standards are
illuminated with tables, graphs and examples. Practical
applications covered are calculating fuel economy, duty cycle
analysis, and capturing intermittent faults. A comparison is made
of various diagnostic approaches including OBD-II, HD-OBD and World
Wide Harmonized (WWH) OBD. Data Acquisition from HD Vehicles Using
J1939 CAN Bus is a must-have reference for those interested to
acquire data effectively from the SAE J1939 equipped vehicles.

Electronic health records (EHRs) play an important role in
optimizing the health care provided to active duty servicemembers
and veterans. When a servicemember leaves military service by way
of discharge, separation, or retirement he or she may become
eligible for VA benefits and services including VA health care.
Transitioning their health care information from one large health
care system (Department of Defense; DOD) to the other (Department
of Veterans Affairs; VA) involves coordination of data and
information between DOD and VA. Longstanding concern that this
exchange be effective has been expressed in many quarters,
including Congress. The purpose of this book is to provide a
background on the long-standing efforts in sharing health
information between DOD and VA. The book also describes changes to
the integrated electronic health record system and evaluates the
departments' current plans; and determines whether the departments
are effectively collaborating on management of the program.
