Konstruktion für die Additive Fertigung 2020
by Roland Lachmayer Katharina Rettschlag Stefan KaierleDie Additive Fertigung hat seit Jahren Ihren Status als Technologie zum Rapid Prototyping überwunden und Einzug in die Serienfertigung von Bauteilen, Werkzeugen und Ersatzteilen gehalten. Diese disruptiv veränderte Perspektive auf die Technologien der Additiven Fertigung führt zu Herausforderungen für Material- und Prozessentwicklung, aber vor allem zu Chancen für völlig neue Lösungen in der Konstruktion, durch z. B. bionische Formgebung, integrierte Effekte und gradierte Materialien.Dieses Buch gibt im Kontext einen Einblick in die aktuelle Forschung und Entwicklung zum Thema „Konstruktion für die Additive Fertigung 2020“ im deutschsprachigen Raum und wendet sich an Experten in Forschung und Wirtschaft. Es verschriftlicht die Vorträge und Diskussionen auf unserem diesjährigen Workshop am Laserzentrum Hannover e.V. mit den Schwerpunkten: Spezifikation von Bauteilen und Prozessen, Methoden zur Abschätzung der Bauteileignung, Innovative Anwendungen der Additiven Fertigung sowie Entwicklung von Konzepten und Entwürfen. Der Workshop wurde unterstützt durch Niedersachsen Additiv und die Wissenschaftliche Gesellschaft für Produktentwicklung e.V.
Konsumentenverhalten im digitalen Kontext: Wie Empfehlungen auf die Einstellungen der Konsumenten im Marketing wirken (Angewandte Wirtschaftsinformatik und angewandte Informatik lernen)
by Susen Poppe Ralf GampferDieses Buch gibt einen ersten Einblick in die Grundlagen des Marketings, insbesondere des Konsumentenverhaltens und betrachtet anschließend, inwieweit sich der digitale Kontext speziell auf das Thema Konsumentenverhaltensforschung auswirkt. Im Fokus des Interesses steht dabei die Einstellungsforschung. Diese wird hinsichtlich ihrer Besonderheiten im Kontext der fortwährenden Digitalisierung aller Lebensbereiche betrachtet. Damit schafft es dieses Buch, neben einer Einführung in das Marketing und das Konsumentenverhalten, die beiden Themenkomplexe, digitaler Kontext und Konsumentenverhaltensforschung, gemeinsamen zu betrachten und Wechselwirkungen eingehend zu beschreiben. Es bietet wichtige Informationen, die für Praktiker ebenso relevant sind wie für Studierende und Lehrende.
Kontaktverfolgung in der Post-Covid-Welt: Ein kryptologischer Ansatz
by Mridul Nandi Subhamoy Maitra Pranab Chakraborty Suprita TalnikarDieses Buch diskutiert modernste Techniken im Bereich der Contact-Tracing-Anwendungen.

Konzeption eines IT-basierten Entscheidungsunterstützungssystems für die Gestaltung dezentraler Datenhaltungen in analytischen Informationssystemen
by Julian ErethDer steigende Stellenwert von Daten als Ressource und die zunehmende Ausweitung des Aufgabenspektrums der IT-basierten Entscheidungsunterstützung verändern die logischen Architekturen analytischer Informationssysteme. Insbesondere die Datenhaltungen entwickeln sich vermehrt von zentralen Konstrukten hin zu dezentralen Konglomeraten verschiedenster Speicheransätze. Die zunehmend heterogenen Technologien und die häufig unzureichenden Erfahrungen mit neuartigen Konzepten erhöhen die Komplexität in der Planung und dem Betrieb analytischer Systemlandschaften. Das Ziel dieser Arbeit ist daher die Konzeption eines IT-basierten Entscheidungsunterstützungssystems für die Gestaltung dezentraler Datenhaltungen in analytischen Informationssystemen. Es wird ein Fachkonzept für die Überführung von Architekturansätzen aus realen Umgebungen in abstrahierte Architekturmuster sowie für die fallspezifische Ableitung von Handlungsempfehlungen entwickelt, prototypisch als Software-Werkzeug implementiert und evaluiert. Das hierbei entwickelte Verständnis eines Architekturmusters ermöglicht durch die Kombination von fachlichen-orientierten analytischen Capabilitites und technischen Aspekten eine ganzheitliche und systematische Unterstützung von IT-Architekturentscheidungen.
Konzeption und Umsetzung automatisierter Softwaretests: Testautomatisierung zur Optimierung von Testabdeckung und Softwarequalität

Dabei werden sowohl die Auswirkungen auf andere Bereiche (z.B. Anforderungsmanagement, Releasemanagement, Entwicklung) als auch aktuelle Trends beleuchtet. Das Buch enthält weiterhin eine Wirtschaftlichkeitsberechnung zur Einführung von Testautomatisierung, Erläuterungen zu möglichen Metriken als auch die Bewertung der Testautomatisierung mittels Prozessreifemodellen.
Kostenoptimierte Anwendungsentwicklung: Reduzierung der Entwicklungskosten durch Trennung der Datenverwaltungs- und Fachfunktionen
by Heinz AppenzellerDas Buch soll keine wissenschaftliche Abhandlungen über Theorien der Informatik oder der Organisationslehre liefern, sondern einen praxiserprobten Weg aufzeigen, wie man durch eine stufenweise, kostenoptimierte und risikoarme Erneuerung der bisherigen Anwendungen eine reaktionsfähige und kontinuierlich erneuerbare Anwendungslandschaft aufbauen und dadurch zu einer hochflexiblen und effizienten Anwendungslandschaft kommen kann. Mit den beschriebenen Methoden können die Kosten der Anwendungsentwicklung um die Hälfte reduziert werden, wenn alle Datenverwaltungsfunktionen in anwendungsneutrale Datentabellen ausgelagert und die Fachfunktionen als selbstständig ablauffähige Geschäftsfall-Apps mit vorgefertigten Softwarekomponenten bedarfsgerecht konfiguriert werden.Dadurch kann eine flexible IT-Unterstützung für die Abarbeitung aller Arbeitsvorgänge entlang den bereichs- und unternehmensübergreifenden Geschäftsprozessen sichergestellt werden, die schnell an die kurzfristigen Veränderungen des dynamischen und komplexen Geschäftsumfelds angepasst werden können.
Kotlin: The Ultimate Guide
by Sufyan bin UzayrKotlin is a free and open-source general purpose programming language that is mostly used to create Android apps. Kotlin was developed by JetBrains initially and later picked up by Google as the language of choice for its Android platform. Over the past few years, Kotlin has become one of the most popular alternatives to Java language and is used by more than 80 percent of Android app developers. Kotlin is a statically typed, advanced programming language that compiles Kotlin code into Java byte-code and runs on a Java Virtual Machine (JVM). It can also be compiled to native executables and JavaScript source code. It is an object-oriented programming language that includes data types, operators, I/O comments, control statements, functions, classes, object expressions, and constructors, among other features. It is not a standalone programming language; rather, it is an innovative manner of coding that runs on Java. Kotlin is a versatile language with some cool features like compatibility, low runtime, and efficient coding characteristics. The features that help distinguish Kotlin from other languages are its reliability, tool support, and interoperability. It is a simplified version of Java that is much easier to deal with. Why Should You Learn Kotlin? The popularity of Kotlin is growing, and will continue to do so in the coming years. Kotlin has always been -- and will continue to be -- a cutting-edge programming language that meets the needs of real professionals. Many emerging fields, including mobile, online gaming, server-side, cloud development, data science, and education, are progressively using Kotlin. All of this indicates that there is already a high demand for Kotlin developers, and that demand will continue to grow in the future. Furthermore, if you are looking to build native Android apps, Kotlin is the language that you should be using.

Kriminalität und Künstliche Intelligenz: Explorative Analyse der Herausforderungen im Umgang mit Deepfakes in Sicherheitsbehörden (BestMasters)
by Robert Diedrich LippitzKünstliche Intelligenz führt zunehmend zu gesamtgesellschaftlichen Veränderungen, die unweigerlich auch kriminelle Handlungsweisen umfassen. Ein vergleichsweise neues Phänomen ist dabei die Nutzung von Deep Learning Software zur Erstellung authentisch wirkender, aber gefälschter, digitaler Inhalte – sog. Deepfakes.
