This well-known undergraduate electrodynamics textbook is now available in a more affordable printing from Cambridge University Press. The Fourth Edition provides a rigorous, yet clear and accessible treatment of the fundamentals of electromagnetic theory and offers a sound platform for explorations of related applications (AC circuits, antennas, transmission lines, plasmas, optics and more). Written keeping in mind the conceptual hurdles typically faced by undergraduate students, this textbook illustrates the theoretical steps with well-chosen examples and careful illustrations. It balances text and equations, allowing the physics to shine through without compromising the rigour of the math, and includes numerous problems, varying from straightforward to elaborate, so that students can be assigned some problems to build their confidence and others to stretch their minds. A Solutions Manual is available to instructors teaching from the book; access can be requested from the resources section at www.cambridge.org/electrodynamics.

Open Circuits is a photographic exploration of the beautiful design inside everyday electronics. Its stunning cross-section photography unlocks a hidden world full of elegance, subtle complexity, and wonder.Our phones, computers, and appliances are made of hundreds of internal components, each precisely engineered to perform a certain function, but none intended to actually be seen. Through painstakingly executed, vividly detailed cross-section photography, Open Circuits reveals the surprising—and often accidental—beauty hiding inside the electronic components that drive our everyday devices. From resistors to LEDs, USB cables to headphone jacks, stepper motors to nixie tubes, the book’s arresting imagery transforms more than 130 components into delightful works of art. As you visually dissect the components’ insides, you’ll learn about how they work and how they were made. Open Circuits has something for everyone to appreciate, whether you’re a seasoned electrical engineer, an amateur tinkerer, or simply a lover of art and photography.

At long last, here is the thoroughly revised and updated, and long-anticipated, third edition of the hugely successful The Art of Electronics.

An up-to-date account of the interplay between optimization and machine learning, accessible to students and researchers in both communities.The interplay between optimization and machine learning is one of the most important developments in modern computational science. Optimization formulations and methods are proving to be vital in designing algorithms to extract essential knowledge from huge volumes of data. Machine learning, however, is not simply a consumer of optimization technology but a rapidly evolving field that is itself generating new optimization ideas. This book captures the state of the art of the interaction between optimization and machine learning in a way that is accessible to researchers in both fields.Optimization approaches have enjoyed prominence in machine learning because of their wide applicability and attractive theoretical properties. The increasing complexity, size, and variety of today''s machine learning models call for the reassessment of existing assumptions. This book starts the process of reassessment. It describes the resurgence in novel contexts of established frameworks such as first-order methods, stochastic approximations, convex relaxations, interior-point methods, and proximal methods. It also devotes attention to newer themes such as regularized optimization, robust optimization, gradient and subgradient methods, splitting techniques, and second-order methods. Many of these techniques draw inspiration from other fields, including operations research, theoretical computer science, and subfields of optimization. The book will enrich the ongoing cross-fertilization between the machine learning community and these other fields, and within the broader optimization community.

Selvom det føles nyt, kan videnskaben om kunstig intelligens spores tilbage til 1956. I bogens første del gennemgår Strümke historien om kunstig intelligens – en historie fuld af mærkelige anekdoter og sjove historier.Udviklingen i de senere år betyder, at StrChatbotten ChatGPT er på kort tid blevet et populært redskab verden over. Teknologien har taget et kvantespring. Men hvad sker der, når brugen af kunstig intelligens sniger sig ind i alle aspekter af vores liv, privat og på jobbet? Hvilke muligheder og hvilke konsekvenser har det?I Maskiner der tænker forklarer Norges førende AI -forsker, hvordan kunstig intelligens fungerer, hvordan mennesker udvikler kunstig intelligens, og hvordan muligheder og potentielle farer opstår ved maskiner, som i tiltagende grad kan tænke selv.Bogen er en indføring i tidens måske mest omdiskuterede teknologi. Forfatteren forklarer de centrale begreber med det formål, at læserne skal forstå, hvordan kunstig intelligens fremover kan præge vores hverdag.Strümke og en række andre forskere mener, at vi denne gang faktisk står på tærsklen til et gennembrud. Der er tegn på, at maskiner bliver klogere end mennesker, og at de snart kan løse problemer, vi i dag ikke aner, hvordan vi skal løse.
