Connected Mobility Applications help to continuously improve traffic safety and efficiency. Today, much time and effort have to be invested to bring an idea into a safe prototype and to finally launch a reliable product.Software development tools have to adapt to these requirements. They have to support a rapid and continuous development process, that allows to test and validate the distributed application as one overall system. When developing cooperative applications, a higher design complexity has to be handled, as components are distributed over heterogeneous systems that interact with a varying timing behavior and less data confidence. Also, test and validation become more complex. Our Innovation Framework is intended to rapidly bring an idea for a connected application into a prototype so the investment risk for innovative applications is reduced. In this whitepaper we describe the approach of a Rapid InnovationTool Kit that is intended to speed up the development process for connected mobility applications. Thereby, a safe and secure prototype is available at an early development phase to gain experience within field tests that help to rapidly improve the intended application. Our software tool kit is able to find deviations from the specified behaviour and also it can instantly locate and identify erroneous functions within distributed systems. Extensive security tests can then be applied on the implemented application to ensure a secure operation. Another use case for the described testbed is to evaluate communication technologies and to find the most suitable transmission technology for a certain application. For example, short range communication with the 802.11p WLAN technology or the upcoming LTE enhancement LTE-V2X are comparable within specific scenarios. This evaluation can help to reduce the investment risk for the deployment of connected applications.

In today’s connected world, the demand for mobile communications and instant access to information, anytime and anywhere, has drastically changed the electronics landscape, both consumer and industrial. Novel 5G and 6G systems will enable connectivity in all forms between humans, devices, machines, and any objects. They will provide virtually ubiquitous, ultra-high bandwidth and low latency network access to individual users, as well as to all objects benefiting from being connected. They will be the "eyes and ears" of Artificial Intelligence systems as it will provide real-time data collection and analysis. Such diversity calls for a new paradigm in terms of flexibility, not only related to performance, but also in terms of scalability and cost. 5G and 6G communication systems imply a major stake of sovereignty and autonomy for the communication sector and digital infrastructures of the future. All products related to IoT, traffic, and health care, supported by connectivity will benefit the citizens in their daily lives to improve everything from business to private affairs. Together, this will influence society as much as smart phones did in the recent past. It is all about communication and connectivity. This book provides an overview of the latest research results in this field. It is based on the close collaboration in the BEYOND5 project, extended with vision and roadmap insights by European experts leading the 6G development. The BEYOND5 project has built a completely European supply chain for Radio-Frequency Electronics, enabling new RF domains for sensing, communication, 5G radio infrastructure and beyond. Moving forward into higher frequency bands above 100 GHz for 6G, also more disruptive technologies, using heterogeneous integration of CMOS, SOI, and III/V components such as GaN or InP, and advanced packaging techniques will be necessary to realize the objectives of ubiquitous, ultra-high bandwidth and low latency networks. The book bundles the scientific content of the International Workshop on "Technologies enabling future mobile connectivity & sensing" in Lisbon, Portugal 10 September 2023, as part of the ESSCIRC/ESSDERC 2023 European Solid-state Circuits and Devices Conference. Through articles and abstracts, a combined view of experts and practitioners representing academia, research, and industry in the field of wireless communication systems is given. They cover the topics of RF and digital SOI technology development for 5 and 6G, device and substrate characterization, packaging technology, and the realization of full systems including power amplifiers, linearization techniques, beamforming transceivers, access points, and radar detection.

Different stakeholders with diverse roles (e.g. software architect or UI designer) involved in a software development process have different information needs. Their information source is a software requirements specification. But, not all information specified, is of the same relevance for all development engineers. So, they are faced with the problem to extract only the relevant parts of the requirements specification. This research paper proposes a concept for a software tool that supports the stakeholders in their work with software requirements documents. A Silver-light business application as a prototype has been developed.

Die vorliegende Querschnittsstudie beschäftigt sich mit dem individuellen Stresserleben und körperlichen Stresssymptomen. Zwei weitere Konstrukte werden in diesem Zusammenhang als mögliche Copingstrategien untersucht. Einerseits die Resilienz, die versucht, kognitiv basierte Verhaltensweisen zu erlernen, um somit die Resilienzwerte zu erhöhen, Andererseits das Selbstmitgefühl, also die an sich selbst gerichtete Freundlichkeit und Güte. Angelehnt an das transaktionale Stressmodell von Lazarus und die Fight-or-Flight Methode sollen diese als Schutzmechanismen das Stresserleben und mögliche damit einhergehende körperliche Stresssymptome verringern. Die theoretischen Ansätze zur Erhöhung der Resilienz und des Selbstmitgefühls basieren auf Risiko- und Schutzfaktoren, sowie positiven, langfristigen Lernzielen, wie die Broaden-and-Build Theorie zeigt. Der Ansatz des Selbstmitgefühls nimmt an, dass Resilienz aus Selbstmitgefühl resultiert. Anhand einer Stichprobe von 273 Befragten wird evaluiert, in welchem Kontext zur Stressbewältigung die eigene Resilienz und das Selbstmitgefühl dienlich sein können. Zur Datenerhebung wurde ein Online-Fragebogen generiert, der über private und berufliche Netzwerke versandt wurde. Die folgenden vier Messinstrumente wurden genutzt: Die Resilienzskala RS-25, die Self-Compassion-Scale SCS-D, das Stress und Coping-InventarSCI und die Perceived Stress Scale PSS-10. Die Daten wurden mit Spearmans Rangkorrelationskoeffizient analysiert. Es wurde jeweils ein negativer Zusammenhang zwischen Resilienz & Selbstmitgefühl mit Stresserleben u nd körperlichen Stresssymptomen festgestellt. Die theoretischen Ansätze werden somit gestützt in der Annahme, dass Resilienz und Selbstmitgefühl sowohl als nützliche Copingstrategie, als auch zur tendenziell positiven Neubewertung (Re-Appraisal) einer Situation oder eines Reizes hilfreich sein kann. Des Weiteren wurde ein positiver Zusammenhang zwischen Resilienz und Selbstmitgefühl bestätigt und damit die Wichtigkeit zur Implementierung präventiver Schutzmaßnahmenwie Selbstmitgefühl bestätigt.
