SIW cavity-backed slot (multi-)antenna systems for the next generation IoT applications

Substrate integrated waveguide (SIW) cavity-backed slot antenna topologies are promising candidates to adress the specific design challenges posed by the Internet of Things (IoT). In this contribution, we demonstrate their potential by discussing two designs on two different, application-specific, innovative substrate materials. First, a compact, ultra-wideband three-element array with very low mutual coupling is presented for integration into furniture. In the second design, the half-mode SIW technique is applied to obtain a miniaturized ultra-wideband design, enabling invisible integration into cork floor and wall tiles. The compactness, integrability, and stable, high performance of both designs in different operating conditions, make them ideal candidates for IoT applications

Benchmarking and viability assessment of optical packet switching for metro networks

Optical packet switching (OPS) has been proposed as a strong candidate for future metro networks. This paper assesses the viability of an OPS-based ring architecture as proposed within the research project DAVID (Data And Voice Integration on DWDM), funded by the European Commission through the Information Society Technologies (IST) framework. Its feasibility is discussed from a physical-layer point of view, and its limitations in size are explored. Through dimensioning studies, we show that the proposed OPS architecture is competitive with respect to alternative metropolitan area network (MAN) approaches, including synchronous digital hierarchy, resilient packet rings (RPR), and star-based Ethernet. Finally, the proposed OPS architectures are discussed from a logical performance point of view, and a high-quality scheduling algorithm to control the packet-switching operations in the rings is explained

Moral Distress and Associated Factors Among Baccalaureate Nursing Students: A Multisite Descriptive Study

Moral distress and its associated negative consequences among postlicensure nurses have been extensively discussed in the literature. Moral distress is defined as knowing the ethically correct action one should take but feeling constrained from acting on one’s convictions because of internal and external constraints (Epstein & Delgado, 2010; Hamric, 2014; Jameton, 1984; McCarthy & Gastmans, 2015; Musto, Rodney, & Vanderheide, 2015). The focus in much of the reviewed literature is on measuring and describing moral distress, moral residue (lingering feelings associated with moral distress), and subsequent deleterious consequences (frustration, apathy, compassio
