A runtime safety analysis concept for open adaptive systems
© Springer Nature Switzerland AG 2019. In the automotive industry, modern cyber-physical systems feature cooperation and autonomy. Such systems share information to enable collaborative functions, allowing dynamic component integration and architecture reconfiguration. Given the safety-critical nature of the applications involved, an approach for addressing safety in the context of reconfiguration impacting functional and non-functional properties at runtime is needed. In this paper, we introduce a concept for runtime safety analysis and decision input for open adaptive systems. We combine static safety analysis and evidence collected during operation to analyse, reason and provide online recommendations to minimize deviation from a system’s safe states. We illustrate our concept via an abstract vehicle platooning system use case
Size Matters: Microservices Research and Applications
In this chapter we offer an overview of microservices providing the
introductory information that a reader should know before continuing reading
this book. We introduce the idea of microservices and we discuss some of the
current research challenges and real-life software applications where the
microservice paradigm play a key role. We have identified a set of areas where
both researcher and developer can propose new ideas and technical solutions.Comment: arXiv admin note: text overlap with arXiv:1706.0735

Self-Driving Cars Will Change Cities
The effects of autonomous vehicles (AVs) on urban forms are modeled, calibrated, and analyzed. Vehicles are used for commute between peripheral home and central work, and require land for parking. An advantage of AVs is that they can optimize the location of day parking, relieving downtown land for other uses. They also reduce the per-kilometer cost of commute. Increased AV availability increases worker welfare, travel distances, and the city size. Land rents increase in the center but decrease in the periphery. Possible locations of AV daytime parking are analyzed. The effects of AV introduction on traffic and on mass transit coverage are discussed
Exploring New Concepts to Create Natural and Trustful Dialogue Between Humans and Intelligent Autonomous Vehicles
In recent years, research on autonomous cars had an ever-increasing spread, exploring many of the technological elements, the intelligence necessary to build hardware and connections, the limits linked to legislation and ethical aspects. The automotive field is rich of interior style solutions, but the topics linked to interaction design and digital user experience are relatively young and need a different approach. In fact, if the higher limits were considered the cognitive workload, the attention and the reaction times required by a still semiautomatic drive, what are the methods to follow in order to obtain an innovative user experience, that also considers the aspects of complexity and of personal digital connections? The presented case study aims to describe the methodological approach and the first concepts developed for the research project that studies an innovative interface system for an autonomous vehicle, able to travel both on the ground and in flight
