    Millimeter-Wave Radio-over-Fiber Links based on Mode-Locked Laser Diodes (2021)
    KIT Scientific Publishing
    Details
    Publikationsdatum: 2024-04-09
    Beschreibung: Radio communications in the range of 60 GHz enable multi-Gigabit/s network access in indoor environments. Due to the propagation characteristics of such signals only very short range radio transmission is feasible. In order to distribute these signals across large distances, analog transmission over optical fiber is considered. In this work, mode-locked laser diodes serve as optoelectronic oscillators for the generation of such signals. Their system-relevant properties are studied in detail.

    The Global Race for Technological Superiority (2021)
    Ledizioni
    Details
    Publikationsdatum: 2023-12-21
    Beschreibung: This report published by ISPI and the Brookings Institution analyzes the challenges to international order posed by the ongoing race for technological superiority. From artificial intelligence and quantum computing to hypersonic weapons and new forms of cyber and electronic warfare, advances in technology have threatened to make the international security environment more unpredictable and volatile – yet the international community remains unprepared to assess and manage that risk. What is needed is a mature understanding of how technology has emerged as a key enabler of sovereignty in the XXI century, how the ongoing race for technological supremacy is disrupting the balance of power globally, and what the attendant strategic and security implications of those transformations will be. This report is an effort to that end.

    MDPI - Multidisciplinary Digital Publishing Institute
    Details
    Publikationsdatum: 2024-04-11
    Beschreibung: The development of solid state gas sensors based on microtransducers and nanostructured sensing materials is the key point in the design of portable measurement systems able to reach sensing and identification performance comparable with analytical ones. In such a context several efforts must be spent of course in the development of the sensing material, but also in the choice of the transducer mechanism and its structure, in the electrical characterization of the performance and in the design of suitable measurement setups. This call for papers invites researchers worldwide to report about their novel results on the most recent advances and overview in design and measurements for applications in gas sensors, along with their relevant features and technological aspects. Original research papers are welcome (but not limited) on all aspects that focus on the most recent advances in: (i) basic principles and modeling of gas and VOCs sensors; (ii) new gas sensor principles and technologies; (iii) Characterization and measurements methodologies; (iv) transduction and sampling systems; (vi) package optimization; (vi) gas sensor based systems and applications.

    Time-dependent spectrum analysis of high power gyrotrons (2021)
    KIT Scientific Publishing
    Details
    Publikationsdatum: 2023-12-21
    Beschreibung: In this work, a novel measurement system for the analysis of the gyrotron RF output spectrum was developed. It enables unprecedented time dependent measurements within a large bandwidth, dynamic range and unambiguous RF indication in the entire D-Band (110-170 GHz). Special attention was given to the investigation of parasitic RF oscillations, and the analysis of the interplay of thermal cavity expansion and ionization-based space charge neutralization at the start of long RF pulses.

    Magnetic Resonance Imaging on Patients with Implanted Cardiac Pacemakers (2021)
    KIT Scientific Publishing
    Details
    Publikationsdatum: 2024-04-09
    Beschreibung: The aim of this work was to identify the patterns that can induce heating around implanted cardiac pacemakers during MRI and to develop strategies to counteract them. Two approaches were taken: computer simulations of the occurring electromagnetic field distributions and in-vitro experiments using phantoms in real MRI devices, both for conventional bore-hole and new open MRI systems. Using the open MRI, the observed heating could be reduced significantly.

    Solution Models based on Symmetric and Asymmetric Information (2021)
    MDPI - Multidisciplinary Digital Publishing Institute
    Details
    Publikationsdatum: 2024-04-11
    Beschreibung: This Special Issue covers symmetry and asymmetry phenomena occurring in real-life problems. We invited authors to submit their theoretical or experimental research presenting engineering and economic problem solution models dealing with the symmetry or asymmetry of different types of information. The issue gained interest in the research community and received many submissions. After rigorous scientific evaluation by editors and reviewers, nine papers were accepted and published. The authors proposed different MADM and MODM solution models as integrated tools to find a balance between the components of sustainable global development, to find a symmetry axis concerning goals, risks, and constraints to cope with the complicated problems. Most approaches suggested decision models under uncertainty, combining the usual decision-making methods with interval-valued fuzzy or rough sets theory, also Z numbers. The application fields of the proposed models involved both problems of technological sciences and social sciences. The papers cover three essential areas: engineering, economy, and management. We hope that a summary of the Special Issue as provided here will encourage a detailed analysis of the papers included in the Printed Edition.

    Middleware Solutions for Wireless Internet of Things (2021)
    MDPI - Multidisciplinary Digital Publishing Institute
    Details
    Publikationsdatum: 2024-04-11
    Beschreibung: The proliferation of powerful but cheap devices, together with the availability of a plethora of wireless technologies, has pushed for the spread of the Wireless Internet of Things (WIoT), which is typically much more heterogeneous, dynamic, and general-purpose if compared with the traditional IoT. The WIoT is characterized by the dynamic interaction of traditional infrastructure-side devices, e.g., sensors and actuators, provided by municipalities in Smart City infrastructures, and other portable and more opportunistic ones, such as mobile smartphones, opportunistically integrated to dynamically extend and enhance the WIoT environment. A key enabler of this vision is the advancement of software and middleware technologies in various mobile-related sectors, ranging from the effective synergic management of wireless communications to mobility/adaptivity support in operating systems and differentiated integration and management of devices with heterogeneous capabilities in middleware, from horizontal support to crowdsourcing in different application domains to dynamic offloading to cloud resources, only to mention a few. The book presents state-of-the-art contributions in the articulated WIoT area by providing novel insights about the development and adoption of middleware solutions to enable the WIoT vision in a wide spectrum of heterogeneous scenarios, ranging from industrial environments to educational devices. The presented solutions provide readers with differentiated point of views, by demonstrating how the WIoT vision can be applied to several aspects of our daily life in a pervasive manner.

    Direct hydroxylation of benzene to phenol in a microstructured Pd-based membrane reactor (2021)
    KIT Scientific Publishing
    Details
    Publikationsdatum: 2023-12-21
    Beschreibung: The gas phase direct hydroxylation of benzene into phenol with hydrogen and oxygen, as initially described by Niwa in 2002, was realized in a newly developed double-membrane reactor. In the concept described by Niwa, a dense Pd membrane is used for the (safe) dosage of dissociated hydrogen species into the tubular reaction zone, where it reacts with gas phase oxygen to form surface species capable of directly converting benzene into phenol in a single-step process.
