This collection reflects on the state-of-the-art of research into the use of translation technologies in the translation of creative texts, encompassing literary texts but also extending beyond to cultural texts, and charts their development and paths for further research.Bringing together perspectives from scholars across the discipline, the book considers recent trends and developments in technology that have spurred growing interest in the use of computer-aided translation (CAT) and machine translation (MT) tools in literary translation. Chapters examine the relationships between translators and these tools - the extent to which they already use such technologies, the challenges they face, and prevailing attitudes towards these tools - as well as the ethical implications of such technologies in translation practice. The volume lends special focus to drawing on examples with and beyond traditional literary genres to look to these technologies' use in working with the larger group of

A textbook that uses a hands-on approach to teach principles of programming languages, with Java as the implementation language.This introductory textbook teaches the principles of programming languages by using an experiential learning style, in which students learn about language features by realizing those features in a pedagogical compiler. Students use Java―the most commonly used programming language in the first two years of the computer science curriculum―as the implementation language throughout. The book also discusses a range of emerging topics in programming languages missing from existing textbooks, including concurrency, Big Data, and event-driven programming. The goal is to prepare students to design, implement, analyze, and understand both domain-specific and general-purpose programming languages. The book first develops basic concepts in languages, including means of computation using primitive values, means of combination such as variable definition and functions, an

Microelectronic Circuits, Eighth Edition, is intended as a text for the core courses inelectronic circuits taught to majors in electrical and computer engineering. It shouldalso prove useful to engineers and other professionals wishing to update their knowledgethrough self-study.As was the case with the first seven editions, the objective of this book is to develop inthe reader the ability to analyze and design electronic circuits, both analog and digital,discrete and integrated. While the application of integrated circuits is covered, emphasisis placed on transistor circuit design, This is done because of our belief that even if themajority of those studying this book were not to pursue a career in IC design, knowledgeof what is inside the IC package would enable intelligent and innovative application ofsuch chips. Furthermore, with the advances in VLSI technology and design methodology,IC design itself has become accessible to an increasing number of engineers.

There are no silver bullets in algorithm design, and no single algorithmic idea is powerful and flexible enough to solve every computational problem. Nor are there silver bullets in algorithm analysis, as the most enlightening method for analyzing an algorithm often depends on the problem and the application. However, typical algorithms courses rely almost entirely on a single analysis framework, that of worst-case analysis, wherein an algorithm is assessed by its worst performance on any input of a given size. The purpose of this book is to popularize several alternatives to worst-case analysis and their most notable algorithmic applications, from clustering to linear programming to neural network training. Forty leading researchers have contributed introductions to different facets of this field, emphasizing the most important models and results, many of which can be taught in lectures to beginning graduate students in theoretical computer science and machine learning.

Advances in computer graphic technologies have inspired new efforts to understand the potential of multimedia instruction as a means of promoting human learning. In Multimedia Learning, Third Edition, Richard E. Mayer takes an evidence-based approach to improving education using well-designed multimedia instruction. He reviews 15 principles of multimedia instructional design that are based on more than 200 experimental research studies and grounded in a cognitive theory of how people learn from words and graphics. The result is the latest instalment of what Mayer calls the Cognitive Theory of Multimedia Learning, a theory introduced in previous editions of Multimedia Learning and in The Cambridge Handbook of Multimedia Learning, Second Edition. This edition provides an up-to-date and systematic summary of research studies on multimedia learning, supplemented with complementary evidence from around the globe. It is well-suited to graduate and undergraduate courses in psychology, educati

Algorithms permeate our lives in numerous ways, performing tasks that until recently could only be carried out by humans. Artificial Intelligence (AI) technologies, based on machine learning algorithms and big-data-powered systems, can perform sophisticated tasks such as driving cars, analyzing medical data, and evaluating and executing complex financial transactions - often without active human control or supervision. Algorithms also play an important role in determining retail pricing, online advertising, loan qualification, and airport security. In this work, Martin Ebers and Susana Navas bring together a group of scholars and practitioners from across Europe and the US to analyze how this shift from human actors to computers presents both practical and conceptual challenges for legal and regulatory systems. This book should be read by anyone interested in the intersection between computer science and law, how the law can better regulate algorithmic design, and the legal ramificatio
