The recent development of cloud computing and edge computing shows great promise for the Connected and Automated Vehicle (CAV), by enabling CAVs to offload their massive on-board data and heavy computing tasks. Leveraging the Internet of Things (IoT) technology, different entities in the intelligent transportation system (e.g., vehicles, infrastructure, traffic management centers, etc.) get connected with each other, thus making the entire system smarter, faster, and more efficient. However, these advances also bring significant challenges to public authorities, industry, as well as scientific communities. In terms of system design and control, current cloud and edge architecture of CAVs need to be refined or even redesigned to better function under uncertainties in demand, and to better cooperate with existing conventional vehicles and infrastructure. From the performance assessment perspective, models and simulation tools based on artificial intelligence and big data have been widely developed for validation and evaluation of cloud computing and edge computing, but the validity of these models needs to be re-examined with field implementations. Finally, while the increasing connectivity among vehicles and infrastructures may help improve their perception of the environment and enable coordinated decision making, it also presents new challenges to ensure system safety and security, with inherent disturbances to wireless communication networks and also the inevitably larger attack surface that may be exploited by malicious attacks. In this tutorial, experts from academia and industry introduce the trends and challenges of applying cloud and edge computing for CAVs, highlight representative works in the literature and discuss their limitations, present new promising solutions, and outline future directions in research and engineering. Particular focus will be given to methodologies and tools for building digital twin frameworks with cloud and edge computing for CAVs, quantitative and formal analysis for ensuring CAV safety under disturbances and uncertainties, system-level CAV security threat landscape and defense solution space, and experiences from practical deployment of cloud and edge computing for CAVs.

Metal additive manufacturing (AM) has gained significant attention due to its ability to produce functional, net-shape parts using laser, electron beam, or binder jetting methods in various industrial sectors. Recent advancements in AM have opened up new opportunities for design freedom and the fabrication of complex geometries such as cellular solids, metamaterials, or biomimetic materials that are not easily achievable using conventional methods. Today, these objects can be created using computer-aided design (CAD) models and elemental or alloyed metallic powders.This Special Issue of Materials, titled "Design and Post Processing for Metal Additive Manufacturing", sought submissions on the design of elements with predicted microstructure and mechanical properties, the use of artificial intelligence/machine learning (AI/ML) in AM, numerical algorithms for AM, and µ-CT magining for quality control.While AM's powder bed manufacturing provides the possibility of fabricating objects of any shape in one production step, it does come with some disadvantages. A major drawback is the need to generate support for the fabricated parts to dissipate the heat generated during the 3D printing process and minimize the geometrical distortions caused by internal stresses from metallic powders. This Special Issue also covers computer simulations and improved fabrication protocols that can help reduce these issues.

Furthermore, the potential use of solar energy for process intensification has been integrated into industrial processes to partially offset a part of the energy requirements, gaining traction toward energy sustainability in the long term. Finally, not overlooking the importance of battery, various processes to recover lithium from oily wastewater sources are reported as well. Overall, this Special Issue undoubtedly captures every important feature of advanced processes in a perpetual intensification and integration for the betterment of both humanity and the natural environment.

Environmental monitoring is a crucial field encompassing diverse applications, including marine exploration, wildlife conservation, ecosystem assessment, and air quality monitoring. Collecting accurate and timely data from inaccessible locations and challenging environments is essential for understanding and addressing environmental issues. Robots offer a promising solution by enabling data collection at unprecedented spatio-temporal scales. However, relying solely on teleoperation is impractical and limits the efficiency and effectiveness of environmental monitoring efforts. Autonomy plays a pivotal role in unlocking the full potential of robots, allowing them to operate independently and intelligently in complex environments. This monograph focuses on high-level decision-making problems in autonomous environmental monitoring robots. Decision-making at the high level involves strategic planning and coordination to optimize data collection. Addressing these challenges allows robots to autonomously navigate, explore, and gather scientific data in a wide range of environmental monitoring applications. Included in the monograph are representations for different environments, as well as a discussion of using these presentations to solve tasks of interest, such as learning, localization, and monitoring. To efficiently implement the tasks, decision-theoretic optimization algorithms consider: (1) where to take measurements from, (2) which tasks to be assigned, (3) what samples to collect, (4) when to collect samples, (5) how to learn environment; and (6) who to communicate. Finally, this work concludes by presenting the challenges and opportunities in robotic environmental monitoring.

This book, drawing on fresh scholarship, investigates electrification in new places and across different time periods. While much of our understanding of electrification as a historical process is based on the seminal work done by Thomas P. Hughes in Networks of Power (1983), the scholars in this volume expand and revise Hughes¿ systems approach to suggest that electrification is a heterogeneous and contingent process. Moreover, the contributors suggest that the conquest of the world by electricity remains incomplete despite more than a century elapsing. Above all, though, this book provides context for thinking about what lies ahead as humans continue their conquest of the earth through electricity. As we become increasingly dependent on electricity to power our lights, heat and cool our homes, turn the wheels of industry, and keep our information systems humming, so we are ever more vulnerable when the grid runs into trouble.Chapter "Surveying the Landscape: The Oil Industry and Alternative Energy in the 1970s" is available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.

An Operations Management Perspective on Design Thinking provides a map of what is known about mechanisms of design thinking when looking through an operations management lens and identifies areas where knowledge gaps still exist. In applying the operations management lens, the author constructs a simple framework for how to assess progress in design thinking activities. To provide improved design thinking progress measures, the author expands this framework by considering multiple dimensions of these measures in greater detail: the outcomes of an operation and its transformation function. Applying the reference set to these multiple dimensions of the expanded framework identifies contributions from other disciplines that can help explain the conditions under which design thinking operations can be managed successfully and pinpoints unexplained gaps that are worthy of future research. The monograph first prepares the methodological ground by putting the attempt to search for better design thinking process measures in the context of existing research approaches. The next section summarizes the origins and characteristics of design thinking and provides an overview of the progress measures that have been proposed for design thinking. The monograph then introduces an operations management perspective for design thinking as an innovation production process. The next section expands this perspective by introducing multiple dimensions and finer grained measures and apply this extended framework to the data set from earlier sections to pull together the current understanding of design thinking and to identify future research opportunities. The monograph concludes with some broader reflections.
