Besides enhanced looks and advanced features, one of the best things about Swing is its pluggable look and feel (PLAF). PLAF architecture allows seamless changes in the appearance of an application and the way an application interacts with the user. However, designing and developing a PLAF is much more exhaustive and complex. On the other hand, themes provide a simple alternative to change look and feel of the swing application. Themes are easier to implement and they enhance the visual appeal of the application UI using the default Java look and feel.
Theme mechanism allows a developer to easily specify the default colors, fonts and icons used by the look and feel (L&F). It allows developers to write their own themes giving them a choice to show their application GUI the way they want it, rather than depending on the defaults provided by the system.

This report presents a tutorial of fundamental array processing and beamforming theory relevant to microphone array speech processing. A microphone array consists of multiple microphones placed at different spatial locations. Built upon a knowledge of sound propagation principles, the multiple inputs can be manipulated to enhance or attenuate signals emanating from particular directions. In this way, microphone arrays provide a means of enhancing a desired signal in the presence of corrupting noise sources. Moreover, this enhancement is based purely on knowledge of the source location, and so microphone array techniques are applicable to a wide variety of noise types. Microphone arrays have great potential in practical applications of speech processing, due to their ability to provide both noise robustness and hands-free signal acquisition.

The surge of mobile data traffic forces network
operators to cope with capacity shortage. The deployment of
small cells in 5G networks is meant to reduce latency, backhaul
traffic and increase radio access capacity. In this context, mobile
edge computing technology will be used to manage dedicated
cache space in the radio access network. Thus, mobile network
operators will be able to provision OTT content providers with
new caching services to enhance the quality of experience of their
customers on the move.

When digital media is perceived only as a tool to deliver content the potential for
using its affordances to explore meaning is lost. Rather than seeing media only as
an access point, we can view it as a way to enhance the expressiveness of content.
Today blogs, wikis, messaging, mash-ups, and social media (Facebook, Twitter,
YouTube and others) offer authors ways to create narrative meaning that refl ects
our new media culture. We can look to the past for similarities and parallels to
better understand how to use social media as a creative tool with which to
dialogue, collaborate, and create interactive narratives.

Telecommunications is today widely understood to mean the electrical means of
communicating over a distance. The first form of telecommunications was that of
the Telegraph, which was invented quite independently in 1837 by two scientists,
Wheatstone and Morse. Telegraphy was on a point-to-point unidirectional basis and
relied on trained operators to interpret between the spoken or written word and the
special signals sent over the telegraph wire. However, the use of telegraphy did
greatly enhance the operations of railways and, of course, the dissemination of news
and personal messages between towns.

The wide deployment of wireless networks and mobile technologies, along with the
significant increase in the number of mobile device users, have created a very strong
demand on various wireless-based, mobile-based software application systems and
enabling technologies. This not only provides many new business opportunities and
challenges to wireless and networking service providers, mobile technology ven-
dors, and software industry and solution integrators, butalso changes and enhances
people’s lives in many areas, including communications, information sharing and
exchange, commerce, home environment, education, and entertainment. Business
organizations and government agencies face new pressure fortechnology updatesto
upgrade their networking infrastructures with wireless connectivity to enhance
enterprise-oriented systems and solutions.

In order to enhance the efficiency and reliability of the power grid, diversify energy
resources, improve power security, and reduce greenhouse gas emission, many
countries have been putting great efforts in designing and constructing their smart
grid(SG) infrastructures.Smart gridcommunicationsnetwork(SGCN) is oneof the
key enabling technologies of the SG. However, a successful implementation of an
efficient and cost-effective SGCN is a challenging task

Sensors are points ofcontact betweenthe material world ofatoms, mass, andenergy
and the seemingly immaterial world of information, computation, and cognition.
Linking these two domains more tightly yields all sorts of practical benefits, such as
improvedinputdevicesforcomputers,moreeffectivemedicaldevices(implantedor
worn), more precise agricultural operations, better monitored buildings or bridges,
more secure payment systems, and more reliable sensor–actuator control systems.
There are many settings in which tighter coupling between digital and physical
planes can enhance safety, security, performance, and reliability.

Signals convey information. Systems transform signals. This book introduces the mathe-
matical models used to design and understand both. It is intended for students interested
in developing a deep understanding of how to digitally create and manipulate signals to
measure and control the physical world and to enhance human experience and communi-
cation.
