The text introduces engineering to first-year undergraduate students using Inquiry-Based Learning (IBL). It draws on several different inquiry-based instruction types such as confirmation inquiry, structured inquiry, guided inquiry, and open inquiry, and all of their common elements. Professor Blum¿s approach emphasizes the student¿s role in the learning process, empowering them in the classroom to explore the material, ask questions, and share ideas, instead of the instructor lecturing to passive learners about what they need to know. Beginning with a preface to IBL, the book is organized into three parts, each consisting of four to ten chapters. Each chapter has a dedicated topic where an initial few paragraphs of introductory or fundamental material are provided. This is followed by a series of focused questions that guide the students¿ learning about the concept(s) being taught. Featuring multiple inquiry-based strategies, each most appropriate to the topic, An Inquiry-Based Approach to Introduction to Engineering stands as an easy to use textbook that quickly allows students to actively engage with the content during every class period.

Quantum science and technology provides new possibilities in processing information, simulating novel materials, and answering fundamental questions beyond the reach of classical methods. Realizing these goals relies on the advancement of physical platforms, among which superconducting circuits have been one of the leading candidates offering complete control and read-out over individual qubits and the potential to scale up. However, most circuit-based multi-qubit architectures onlyinclude nearest-neighbor (NN) coupling between qubits, which limits the efficient implementation of low-overhead quantum error correction and access to a wide range of physical models using analog quantum simulation

Over the last few years, many smartphones have been equipped with Global Navigation Satellite System (GNSS) technology, allowing people to use their own devices for positioning and location services. After the release of the Android Nougat (version 7) operating system, raw GNSS measurements (i.e., pseudorange, carrier-phase, Doppler shift, and carrier-to-noise density ratio (C/N0) observations) from smartphones and tablets became accessible, which opened the door to precise positioning capabilities in consumer devices. Many studies have since been conducted, as precise location information will lead to many new smartphone applications in the near future. While the progress has been encouraging, a number of limiting factors must be overcome in order to support real-world applications, including poor antenna quality, the difficulty of carrier phase ambiguity resolution, and low availability and integrity in operational environments. The contributions from academia and industry included in this reprint discuss innovative ideas and algorithms and present experimental results for precise positioning with Android smartphones.

Due to the increasing importance of considering the socio-environmental issues in recent decades, most of today's critical systems should pursue sustainability-related objectives while meeting operational goals. Furthermore, sociotechnical systems working with complex operations represent dynamic complexity, relative ignorance, and intractability, which entail interactive and dependent social elements and organizational and human activities. Considering the influence of and the relationship between operational concerns such as risk, reliability, and resilience and strategic concerns such as sustainability helps managers and policy-makers make more reliable and efficient decisions in a wide range of engineering and management systems. This reprint tries to extend the available knowledge on the extent and quality of such interactions and discusses how one can ensure that reliability and resilience are maintained over dynamic conditions to achieve a sustainable operation. Under these conditions, most existing engineering and management systems in various industries (e.g., food, mining, and construction) should be required to undergo adaptive improvements to become more resilient to potential future typical or extraordinary circumstances. This reprint also sheds light on the challenges and future directions which the research community should focus on and introduces various approaches and applications to develop more sustainable and resilient solutions in both engineering and management systems.

In diesem Buch wird das Laser-Pulver-Auftragschweißen betrachtet, ein variabel einsetzbares generatives Fertigungsverfahren, das spezifische Vorteile in den Industriezweigen Beschichten, Reparieren und mittlerweile auch in der additiven Fertigung (3D-Druck) aufweist. Um das vollständige Potenzial als ressourcenschonende Technologie nutzen zu können, sind jedoch noch unterschiedliche Aufgabenstellungen entlang der Prozesskette zu optimieren. In der Anwendung lassen sich starke Abhängigkeiten zwischen der Bauteilgeometrie und dem Prozess beobachten, sodass nach heutigem Stand keine einheitliche Aufbaustrategie für beliebige Bauteile angewendet werden kann. Durch signifikante Unterschiede der thermischen Randbedingungen im Prozess und zwischen den Bauteilgeometrien wird oftmals eine variierende Prozessstabilität und damit auch Bauteilqualität beobachtet. Es ist somit stets eine iterative, meist experimentelle Prozessoptimierung notwendig. Diese erfordert Expertenwissen und geht mit hohenRessourcenkosten sowie langen Entwicklungszeiten einher. Folglich ist eine breite Industrialisierung dieses Verfahrens speziell für die additive Fertigung nach wie vor eingeschränkt. Um diesem Defizit entgegenzuwirken, wird in dem vorliegenden Buch eine temperaturadaptive Prozessauslegung vorgestellt. Auf Grundlage von empirisch ermittelten Daten und einer thermischen Simulation wird eine automatisierte Generierung einer angepassten Prozessstrategie für beliebige Bauteile ermöglicht.

Trotz großer Verbesserungen in der Versorgung von Menschen mit Typ-1-Diabetes (MmT1D) werden auch bei hoher Motivation und hohem Wissensstand der T1D-Grundlagen und -Therapie die angestrebten Blutglukose-Werte häufig nicht erreicht. Daher hat sich aus der Gruppe der MmT1D und ihrer Angehörigen eine Gemeinschaft zusammengefunden, die auf Basis kommerzieller Technologien sogenannte Open-Source-Closed-Loop-Systeme (OSCLS) entwickelt, welche eine automatisierte Insulinabgabe ermöglichen. OSCLS haben das Potenzial, das Management der Erkrankung zu erleichtern und normnähere Blutglukose-Werte zu erzielen. Die OSCLS sind jedoch weder offiziell geprüfte noch zugelassene Systeme. Aus dem Blickwinkel der Technikfolgenabschätzung untersucht die vorliegende Arbeit mittels leitfadengestützter qualitativer Interviews mit Nutzenden und Fachkräften vorrangig, warum sich die Nutzenden der OSCLS für die Systeme entscheiden und wie sich diese auf das Leben der Nutzenden sowie auf das Gesundheitswesen auswirken. Zudem ordnet diese Arbeit die OSCLS-Bewegung in vergleichbare aktivistische Bewegungen in Medizin und Gesundheit ein sowie in den Kontext der derzeit immer stärker werdenden Bewegung der Patient Innovation.

Billig-Fluggesellschaften gibt es in Europa seit der Liberalisierung des Luftverkehrs in den späten 1990er-Jahren. Ihre Ausrichtung und der Charakter haben sich im Laufe der Zeit immer wieder gewandelt. Mittlerweile gibt es bereits erste ¿Ulträ-Billigfluglinien. Auf der anderen Seite lassen sich auch viele etablierte Airlines auf den Preiskampf ein, so dass die Unterschiede zum Teil verschwimmen. Vor 25 Jahren waren die Auswirkungen des Klimawandels und seine Folgen für den Luftverkehr noch wenig erforscht, heute kommt den Billigfliegern mit ihrer schwierigen Umweltbilanz teilweise die Rolle eines Buhmanns zu. Können Billigflieger in diesem immer schwieriger werdenden Umfeld überleben? Schadet der permanente Kostendruck der Sicherheit? Sollen sie auf die ökologisch sinnvollere Langstrecke ausweichen? Bringen Kooperationen die Wende? Diese und viele andere Fragen werden von dem branchenerfahrenen Autor untersucht. Das Fazit dürfte den einen oder anderen überraschen. A Silicon Valley soldier of fortune builds an electric car and turns a large fortune into a small one. That could be the end of the story. He wouldn't have been the first. Fisker, Coda, Better Place, Aptera, the list has plenty of room for losers. But even looking through the sunglasses, Tesla has made it. In many ways. Great cars, hyped like Apple, a functioning infrastructure, while the competition is still arguing with local suppliers about plug sizes. A total package that feels like it's miles ahead of the competition. How was that possible? Was everyone asleep? Why Tesla of all companies? And what will happen when autonomous driving arrives? Will Apple and Google take over then? Or does Tesla have the answer here too? The author works as an analyst in the automotive industry and has been closely observing the chaotic development of electromobility for years.
