Bilingualism and multilingualism both make a major contribution in cross-cultural interaction, but, at the same time, improve various cognitive abilities, such as better attention and multitasking. Meaning in the world around us is represented by means of the language that is used for communication and knowledge exchange between intelligent individuals. The phenomena of human interaction and communication are recently experiencing unprecedented influence from digital technologies. Language learning is part of the global revolution, meaning that language learning technologies are playing an increasingly important role in learning English for Specific Purposes. This volume addresses theoretical and practical aspects of learning, technology adoption and pedagogy in the context of English for Specific Purposes.

Fossil fuels are limited resources and are anticipated to be exhausted within the next few decades. Solar energy is the only renewable resource capable of adequately meeting today's total global energy demand. Dye-sensitised solar cells (DSCs) represent a novel class of photovoltaic devices that mimic nature's photosynthesis process. This book focuses on the possibilities of optimising the dye-sensitised solar cells' efficiency, and also presents the historical background of DSCs, their efficiency timeline, key components, and the principle of operation. Some powerful nanotechnology tools and methods used to investigate and enhance this type of solar cell are also presented in detail. The methods and findings detailed here combine both experimental and computational studies. They pave the way towards enhancing the efficiency of dye-sensitised solar cells.

In recent decades, media theory has become one of the most influential trends in contemporary thinking, namely within cultural studies, the arts and humanities. Spreading mostly from the German scholarly scene, under the influence of post-structuralism, media theory has developed as a fundamental theoretical framework, for many fields of theoretical and applied research, through authors such as the late Friedrich Kittler, 1943-2011. Commenting on several aspects of Kittler's work, and on its impact in different fields of art and culture, this essay collection examines recent developments in media theory brought about by concepts such as "cultural techniques" and "operative ontologies" and by key authors, contributing to this volume, such as Bernhard Siegert, Sybille Kramer and Peter Weibel.

Decreasing power dissipation per logic function has become a primary concern in virtually all CMOS system chips designed today as a result of the relentless progress in processing technology that has led us into the deep-submicron age. Evolution from 1 micron to 0.1 micron lithography in the next decade will not be possible without a change in the way we design CMOS systems. But power reduction requires an overall optimisation, ranging from software compilation over instruction set design down to the introduction of much more parallelism in the architecture, the optimal use of memory hierarchy, new clocking strategies, use of asynchronous techniques, new CMOS circuit techniques and management of leakage currents in new low power technologies. Moreover, performance and power dissipation will come to be dominated by interconnect and thus completely new floor planning and place and route strategies are emerging. The chapters in this book present a systematic coverage of deep submicron CMOS digital system design for low power, from process technology all the way up to software design and embedded software systems. Audience: An excellent guide for the practising engineer, researcher and student interested in this crucial aspect of actual CMOS design.
