Recent advances in mobile and wireless communication and personal computer technology have created a new paradigm for information processing. Today, mobile and wireless communications exit in many forms, providing different types of services. Existing forms of mobile and wireless communications continue to experience rapid growth and new applications and approaches are being spawned at an increasing rate. Recently, the mobile and wireless Internet has become one of the most important issues in the telecommunications arena. The development of the mobile and wireless Internet is the evolution of several different technologies coming together to make the Internet more accessible. Technologies such as the Internet, wireless networks, and mobile computing have merged to form the mobile and wireless Internet. The mobile and wireless Internet extends traditional Internet and World Wide Web services to wireless devices such as cellular phones, Personal Digital Assistants (PDAs) and notebooks. Mobile and wireless Internet c: an give users access to personalized information anytime and anywhere they need it, and thus empower them to make decisions more quickly, and bring them closer to friends, family, and work colleagues. Wireless data communication methods have been around for sometime
Are people with autism giving us a glimpse into our future human condition? Could we be driving our own evolution with our technology and, in fact, be witnessing the beginning of the next stage of human evolution? The thesis at the center of this book is that since we have delegated the ability to read context to contextual technologies such as social media, location, and sensors, we have become context blind. Since context blindness-or caetextia in Latin-is one of the most dominant symptoms of autistic behavior at the highest levels of the spectrum, people with autism may indeed be giving us a peek into our human condition soon. We could be witnessing the beginning of the next stage of human evolution-Homo caetextus. With increasingly frequent floods and fires and unbearably hot summers, the human footprint on our planet should be evident to all, but it is not because we are context blind. We can now see and feel global warming. We are witnessing evolution in real-time and birthing our successor species. Our great-grandchildren may be a species very distinct from us. This book is a must for all communication and media studies courses dealing with digital technology, media, culture, and society. And a general reading public concerned with the polarized public sphere, difficulties in sustaining democratic governance, rampant conspiracies, and phenomena such as cancel culture and the need for trigger warnings and safe spaces, will find it enlightening.
Archiving has become an increasingly complex process. The challenge is no longer how to store the data but how to store it intelligently, in order to exploit it over time, while maintaining its integrity and authenticity. Digital technologies bring about major transformations, not only in terms of the types of documents that are transferred to and stored in archives, in the behaviors and practices of the humanities and social sciences (digital humanities), but also in terms of the volume of data and the technological capacity for managing and preserving archives (Big Data). Archives in The Digital Age focuses on the impact of these various digital transformations on archives, and examines how the right to memory and the information of future generations is confronted with the right to be forgotten; a digital prerogative that guarantees individuals their private lives and freedoms.

Comprehensive and accessible guide to the three main approaches to robust control design and its applications Optimal control is a mathematical field that is concerned with control policies that can be deduced using optimization algorithms. The optimal control approach to robust control design differs from conventional direct approaches to robust control that are more commonly discussed by firstly translating the robust control problem into its optimal control counterpart, and then solving the optimal control problem. Robust Control Design: An Optimal Control Approach offers a complete presentation of this approach to robust control design, presenting modern control theory in an concise manner. The other two major approaches to robust control design, the H_infinite approach and the Kharitonov approach, are also covered and described in the simplest terms possible, in order to provide a complete overview of the area. It includes up-to-date research, and offers both theoretical and practical applications that include flexible structures, robotics, and automotive and aircraft control. Robust Control Design: An Optimal Control Approach will be of
interest to those needing an introductory textbook on robust
control theory, design and applications as well as graduate and
postgraduate students involved in systems and control research.
Practitioners will also find the applications presented useful when
solving practical problems in the engineering field.

Actuators are devices that convert electrical energy into
mechanical work, traditionally used in electrical, pneumatic and
hydraulic systems. As the demand for actuator technologies grows in
biomedical, prosthetic and orthotic applications, there is an
increasing need for complex and sophisticated products that perform
efficiently also when scaled to micro and nano domains.
This book took shape at the unique interdisciplinary engineering school at Dartmouth College. It assumes engineers of all stripes may end up working in technical areas impacted by Nonlinear Optics (NLO) and would benefit by learning about the field. Each section follows a set format, beginning by describing some exciting new technology made possible by NLO. This is followed by a description of the background information necessary for students to understand the basic NLO concepts for that application. The author occasionally includes personal experiences as a pioneer in this field where it provides additional understanding and motivation. Each section ends with a description of other developments in technology that use the same NLO concept.
E-PAPER DISPLAYS An in-depth introduction to a promising technology, curated by one of its pioneering inventors Electronic paper (e-paper) has one of the most promising futures in technology. E-paper's potential is unlimited, as the displays require extremely low power and imitate the aesthetic of ink on the page. This allows e-paper devices to have a wider range of viewing angles than traditional LED products and are capable of being viewed in direct sunlight--and without any additional power. As a result, e-paper displays create less eye strain, have a greater flexibility in their use, and have the potential to be used in place of paper for billboard advertising, educational applications, and transport signage, and more. In E-Paper Displays, editor Bo-Ru Yang and his team of experts present a detailed view into the important technologies involved in e-paper displays, with a particlular emphasis on how this technology's unique properties make possible a wide range of personal and professional electronic products. As climate change makes efficient energy use more important than ever, e-paper can become an essential tool for future products on a large scale. As we rely more and more on technology, having lightweight devices with long battery life will become critical. This book provides engineers and innovators with an introduction to this important technology and shows new pathways for development. E-Paper Displays readers will also find: The editor is one of the leading pioneers in this technology Contributions from an international team of experts in e-paper technology Descriptions of many advanced display types that rely on different principles than the widely used LCD and OLED types Another innovative title from Wiley-SID (Society for Information Displays) series As we enter a new stage in our industrial development, E-Paper Displays is an essential reference for computer engineers and developers, as well as innovators and scientists, and their students.
