Performance Testing
Use this book to prepare for the ISTQB® Certified Tester Foundation Level Performance Testing exam. The book has been designed to follow the ISTQB syllabus, covering all of the syllabus learning objectives, with additional reference material extending beyond the syllabus. The book covers an overall methodology for managing and conducting performance testing.Performance testing has often been considered a black art. In many organizations, perhaps an individual or a small group of technical staff or contractors is given the task of “load testing” an extended system, network, or application.Performance testing is like any other form of testing. It follows a defined test process that is similar to other test types. It utilizes a disciplined approach to the definition of requirements and user stories, the creation of test conditions, test cases, and test procedures. It establishes measurable goals against which the success or failure of the testing can be judged. It also requires (and this cannot be stressed highly enough) a definition and recognition of performance test failures.Readers will gain the knowledge with both content and practice questions to prepare them for the ISQTB Performance Testing exam. The book covers the performance test types, the performance testing methodology, and the steps to plan, create, and execute performance tests and analyze the results.WHAT YOU WILL LEARN* Understand the basic concepts of performance efficiency and performance testing* Define performance risks, goals, and requirements to meet stakeholder needs and expectations* Understand performance metrics and how to collect them* Develop a performance test plan for achieving stated goals and requirements* Conceptually design, implement, and execute basic performance tests* Analyze the results of a performance test and communicate the implications to stakeholders* Explain the process, rationale, results, and implications of performance testing to stakeholders* Understand the categories and uses for performance tools and criteria for their selection* Determine how performance testing activities align with the software life cycleWHO THIS BOOK IS FORThose who want to achieve the ISTQB performance testing certification, testers and test managers who want to increase their performance testing knowledge, and project managers/staff working with performance testing in their project for the first timeAfter a circuitous route into IT, KEITH YORKSTON has spent the last 20 years involved with software quality and risk.

Artificial intelligence and the future of warfare
This volume offers an innovative and counter-intuitive study of how and why artificial intelligence-infused weapon systems will affect the strategic stability between nuclear-armed states. Johnson demystifies the hype surrounding artificial intelligence (AI) in the context of nuclear weapons and, more broadly, future warfare. The book highlights the potential, multifaceted intersections of this and other disruptive technology – robotics and autonomy, cyber, drone swarming, big data analytics, and quantum communications – with nuclear stability. Anticipating and preparing for the consequences of the AI-empowered weapon systems are fast becoming a critical task for national security and statecraft. Johnson considers the impact of these trends on deterrence, military escalation, and strategic stability between nuclear-armed states – especially China and the United States. The book draws on a wealth of political and cognitive science, strategic studies, and technical analysis to shed light on the coalescence of developments in AI and other disruptive emerging technologies. Artificial intelligence and the future of warfare sketches a clear picture of the potential impact of AI on the digitized battlefield and broadens our understanding of critical questions for international affairs. AI will profoundly change how wars are fought, and how decision-makers think about nuclear deterrence, escalation management, and strategic stability – but not for the reasons you might think.

Semantische Datenintelligenz im Einsatz
Semantische Technologien haben mit der Entwicklung von datenbasierten Systemen wie Neuronale Netze, Deep Learning und Machine Learning ihre Bedeutung nicht verloren, sondern werden als effiziente wissensbasierte Systeme immer wichtiger. Denn intelligente Systeme der Zukunft müssen nicht nur in der Lage sein zu sagen, was sie entschieden haben, sondern auch wie sie zu dieser Entscheidung gekommen sind. Solche Systeme sind jedoch nur mit Hilfe von wissensbasierten Systemen auf der Grundlage von semantischen Technologien erreichbar. Heute reichen die Anwendungen von semantischen Systemen von der semantischen Suche, Knowledge Graphs, Chatbots, NLP, in der Medizin bis zur Telekommunikation, Verwaltung und Robotik. Semantische Technologien werden spätestens mit dem Voranschreiten des Internet of Things (IoT) und Industrie 4.0 Anwendungen allgegenwärtig sein. Dies ist unumgänglich, denn ohne sie ist auch die Interoperabilität unter Maschinen und insbesondere unter Roboter für eine intelligente Zusammenarbeit und Produktion nicht so einfach umsetzbar. Dafür gibt es bereits heute zahlreiche Beispiele aus der Industrie.DIPL.-ING. BÖRTEÇIN EGE studierte Informatik an der Technischen Universität Wien.

High-Quality Illumination of Virtual Objects Based on an Environment Estimation in Mixed Reality Applications
Visualizations of virtual objects in the real environment is often done by a simplified representation with simple surfaces and without reference to the surrounding environment. The seamless fusion of the virtual and real environment is, however, an essential factor in many areas, which is of particular importance when calculating lighting in mixed realities on mobile devices. Current approaches focus on approximations, which allow the calculation of diffuse lighting, whereby the rendering of glossy reflection properties is often neglected. The aim of this book is to enable the visualization of mirror-like reflective surfaces in mixed reality. In order to achieve this goal, various approaches are explored enabling high-quality visualization of virtual objects in realtime with a focus on the use of common hardware such as cameras, sensors in mobile devices, and partially depth sensors. Complete ambient lighting can be estimated, which enables detailed reflections. The results provide a novel way to embed complex and simple geometric shapes with glossy surfaces in the real world which offers a higher level of detail in the reflections without using additional hardware.TOBIAS SCHWANDT´S professional and personal focus at the TU Ilmenau is the area of Mixed-Reality (MR). Within his dissertation, he particularly concerned himself with the topic of illumination of virtual content in AR, its influence on the real environment, the reconstruction of the environment light, and the manipulation of real geometry by virtual content.Introduction.- Fundamentals & State of the Art.- Illumination in Mixed Reality.- Realization.- Results.- Discussion & Limitations.- Conclusion & Outlook.
