The structural set-up and key characteristics of regulatory regimes for risk management vary between countries, technical domains and application areas. Risk regulations come in different forms, ranging from a highly prescriptive (“hard”) approaches including explicit requirements on key risk management components, to “softer” approaches requiring risk to be managed without defining how. Risk regu
During the last few years, with the decrease of their sizes and costs, Unmanned Aerial Vehicles (UAVs) became more feasible for their use in general-purpose applications. As an important basis for UAV applications, the Air-to-Ground (A2G) radio propagation channel has gained attention in the channel modeling literature. However, whereas the A2G propagation channel is inherently dynamic (time-varyi
When working with system development and design, one is urged to write design documentation. The design document should be constructed in a specific way and should include all necessary information. However, the users of the design document are not stated and seem to be secondary. This study's aim is therefore to investigate who the users are. A literature review was conducted to answer the questi
Supercritical n-decane is applied in the regenerative cooling system of scramjet engines while scramjets are always in various irregular movements. With the desire to explore heat transfer performance of supercritical n-decane under actual flight conditions, numerical simulations and analysis of different states during the accelerated flight process are carried out under three different heat fluxe
Plastic anisotropy may strongly affect the stress and strain response in metals subjected to multiaxial cyclic loading. This anisotropy evolves due to various microstructural features. We first use simple models to study how such features result in evolving plastic anisotropy. A subsequent analysis of existing distortional hardening models highlights the difference between stress- and strain-drive
Differences between 10Be records from Greenland and Antarctica over the last 100 years have led to different conclusions about past changes in solar activity. The reasons for this disagreement remain unresolved. We analyze a seasonally resolved 10Be record from a firn core (North Greenland Eemian Ice Drilling [NEEM] ice core project) in Northwestern Greenland for 1887–2002. By comparing the NEEM d
The aim of this paper is to reflect on the conceptualization of three, a priori, similar territorial innovation models: the triple helix, the regional innovation systems and Sábato’s triangle. To compare their underlying theoretical foundations, we conduct a bibliometric analysis of the contributions based on the previous territorial innovation models. Following Reinert’s procedure we identify the
Based on extensive ethnographic fieldwork in Uzbekistan, this article looks at the way official state narratives are challenged by silent, unorganized, often unawares, gestures of resistance at the bottom of a society. Footing on a framework suggested by Scott’s definition of infrapolitics (2012), we propose to incorporate informal practices in a definition of informality that is more inclusive, a
One of the most important measures to evaluate air quality is the presence of particles. Pin-on-disc tribometers are used to study airborne wear particles originating from different sliding contacts in a controlled laboratory environment. One important aspect when measuring airborne particles is to ensure isokinetic sampling conditions. Another important aspect is that the concentration and the pa
This Letter presents the first experimental evidence of the attractive strong interaction between a proton and a φ meson. The result is obtained from two-particle correlations of combined p-φ p¯-φ pairs measured in high-multiplicity pp collisions at s=13 TeV by the ALICE Collaboration. The spin-averaged scattering length and effective range of the p-φ interaction are extracted from the fully corre
Citizen science is changing society's contribution to research projects worldwide. Non-experts are no longer just spectators, they are active participants and supporters of scientific work. Using citizen science, that is, data collected by laypeople, the opportunities to collect large-scale data on the environment are increasing. Such community-based and citizen scientific approaches can provide u
Decellularized tissues, native or engineered, are receiving increasing interest in the field of regenerative medicine as scaffolds or implants for tissue and organ repair. The approach, which offers the opportunity to deliver off-the-shelf bioactive materials without immuno-matching requirements, is based on the rationale that extracellular matrix (ECM)-presented cues can be potently instructive t
Collaboration between academia and actors outside academia (AOAs) has been proclaimed as a way for society to confront challenges in different fields. This ‘participatory imperative’ is anchored in EU research policy. The paper explores the participatory imperative in contemporary Swedish aging research. Three kinds of motives for participatory research as a way to societal impact emerged in the s
A quantitative evaluation method for nonlinear elastic characteristics of piezoelectric materials in high-power operation using constant current (CC) measurements was established. The admittance curves obtained from conventional constant voltage measurements are unsuitable for curve fitting to determine the nonlinear coefficients, due to the hysteresis and jump phenomena in the admittance curve. T
Carbon moves through the atmosphere, through the oceans, onto land, and into ecosystems. This cycling has a large effect on climate – changing geographic patterns of rainfall and the frequency of extreme weather – and is altered as the use of fossil fuels adds carbon to the cycle. The dynamics of this global carbon cycling are largely predicted over broad spatial scales and long periods of time by
Moisture‐induced deterioration is critical to building envelope durability in cold and temperate climates. To propose a new framework for selecting moisture design periods (MDPs) in Swedish building assemblies that capture sever moisture conditions more accurately, this paper evaluates different methods for producing MDPs. Using a 30‐year historical weather dataset as a benchmark, we compared simu
