Increasing renewable integration is posing new challenges to reliability of power networks. One of these challenges is to restart the power network and energize power transformers in the event of a blackout. Grid forming converters can provide a potential solution to this issue because they can be controlled as independent, self starting, voltage sources. This study analyzes and compares four grid
Implementing solar photovoltaic systems in the built environment (BEPV) is critical for the construction sector’s contribution to mitigating climate change. While previous studies give various insights into innovation implementation, the challenges to value co-creation by construction actors remain underexplored. By studying the alignment of business ecosystems implementing BEPV in the Swedish bui
The pulp and paper industry is one of the most important industries in the world. The current pulp mills focus on the production of pulp fiber and electricity. By converting traditional pulp mills into lignocellulosic biorefineries, they can become a cornerstone of a future circular bioeconomy. To achieve this, pulp mills need to close their cycles and focus on making the most of the lignocellulos
Föreliggande undersökning syftar till att utvärdera möjligheten att använda bioimpedansspektrometri för att mäta tumör- och vävnadsrespons på strålterapi. Bioimpedansmätningar utförda med CythorLab ™ utrustade med en signalgenerator med en känd högutgångsimpedans och signalmätanordning som kan mäta spänningen som appliceras av generatorn. Styrenheten utlöser signalgeneratorn som genererar en MLS-sThe present investigation aims to evaluate the possibility of using bio-impedance spectrometry to measure tumour and tissue response to radiation therapy. Bio -impedance measurements performed with CythorLab™ equipped with a signal generator with a known high output impedance and signal measuring device able to measure the voltage applied by the generator. The control unit triggers the signal gene
Solar radiation plays a pivotal role in the energy balance at the Earth's surface, evaporation, snow melting, water requirements of plants, and hydrological control of catchments. In this work, performance of ERA-Interim (a reanalysis dataset) was examined to estimate solar radiation at Ahvaz, BandarAbbas, and Kermanshah weather stations representing the even spatial distribution over Iran using e
Nickel-based superalloys are typical materials used in components of aeroengines and gas turbine machinery. The strength properties of these alloys at high temperatures are crucial not only to the performance (e.g., power generation efficiency, energy consumption, and greenhouse gas emissions) of aeroengines and industrial gas turbines, but also to machinability during component manufacturing. Thi
In the present study a phase field model for high surface energy anisotropy is developed to model the morphologies of voids in UO2. In order to precisely account for the high anisotropy, an alternative forward-backward strategy based on a staggered grid with an averaged interface normal scheme is used in the numerical procedure. A variety of equilibrium void shapes are reproduced with respect to a

Objectives: Patients with SLE have an increased risk of comorbidities and impaired survival. We aimed to assess whether various thresholds of oral CS (OCS) can predict development of infections, comorbidities, malignancies and survival in SLE using data from national health registries in Sweden. Methods: All incident SLE cases, age >18 years, in Sweden (n ¼ 5309) between 2005 and 2020 and matched
