In a smart grid setting, building managers are encouraged to adapt their energy operations to real-time market and weather conditions. However, most literature assume stationary temperature set points for heating and cooling. In this work, we propose a grey-box model to investigate how the energy...

Purpose Cancer is among the leading causes of death in the developed world, and lung cancer is the most lethal type. Early detection is crucial for better prognosis, but can be resource intensive to achieve. Automating tasks such as lung tumor localization and segmentation in radiological images...

The Al2O3–CaO–SiO2 ternary is a basic oxide system relevant for the Pedersen alumina production process and for aluminothermic silicon production with low environmental impact using secondary aluminium and silica raw materials. Rheological property is one of the most important properties for the...

Innovative enhanced oil recovery (EOR) technologies are needed to ensure a more economical oil production to meet the growing energy demand. Silica nanoparticles have been widely studied for EOR applications due to their unique physical and chemical properties. Recent studies have proposed a renewed...

The dominating technology of solar cell production today is based on monocrystalline silicon, produced mostly by the Czochralski process. Recently, the solar cell industry, has started to move towards growing larger and better-performing ingots. This triggered a need for crucibles that can withstand...

The surface reactivity during CO oxidation over Pd(1 1 1) and Pd75%Ag25%(1 1 1) single crystals has been investigated using near ambient pressure X-ray photoelectron spectroscopy (NAP-XPS) under excess oxygen conditions (p ≈ 2 mbar, O₂:CO=10). The (√6×√6) Pd5O4 surface oxide is present on Pd...

Tourism transport may lead to significant air emissions and congestion problems on road networks. This is particularly troublesome for nature-based tourism destinations, as they often are in rural areas with low transportation capacities and vulnerable nature. Tourism transport systems are poorly...

The building construction industry has a significant potential to develop and apply energy efficient solutions, and hence contribute to address climate and environmental concerns. Energy efficient solutions are applied not only in new buildings, but also in refurbishment / renovation of existing...

Iron alloys were produced by suspension electrolysis in a 50 wt% NaOH–H₂O electrolyte at 383 K, and Fe–Cr and Fe–Ni alloys were obtained using a suspension of Fe2O3+Cr2O3 and Fe2O3+Ni(OH)2 particles, respectively. Highly ordered columnar deposits comprising cubic Fe–Cr particles with approximately...

It is now more than 80 years since Alkali Aggregate Reactions (AAR) first were reported as a deleterious deterioration mechanism in concrete. In Norway, AAR was recognised in the late nineteeneighties. Norwegian experience and expertise have increased significantly since then and entered the...

The irreversible transition towards urban living entails complex challenges and vulnerabilities for citizens, civic authorities, and the management of global commons. Many cities remain beset by political, infrastructural, social, or economic fragility, with crisis arguably becoming an increasingly...

A novel method coupling computational fluid dynamics (CFD) and finite element method (FEM) was developed to account for the complex physics of the reciprocating compressor. The developed method is based on data exchange between the two solvers at each time step. We address the challenges related to...

A full smart grid implementation requires the digitization of all parts of the smart grid infrastructure, including secondary electrical substations. Unfortunately, this introduces new security threats, which were not apparent before. This article uses a Smart Grid Threat Modeling Template...

Energy Systems Modelling is growing in relevance on providing insights and strategies to plan a carbon-neutral future. The implementation of an effective energy transition plan faces multiple challenges, spanning from the integration of the operations of different energy carriers and sectors to the...

In this study we have compared two modalities for flow quantification from measurement data; ultrasound (US) and shadow particle image velocimetry (PIV), and a flow simulation model using computational fluid dynamics (CFD). For the comparison we have used an idealized Quasi-2D phantom of the human...

Acoustic Cluster Therapy (ACT®) is a platform for improving drug delivery and has had promising pre-clinical results. A clinical trial is ongoing. ACT® is based on microclusters of microbubbles–microdroplets that, when sonicated, form a large ACT® bubble. The aim of this study was to obtain new...

Digital transformation has been one of the most studied phenomena in information systems (IS) and organizational science literature. With novel digital technologies emerging at a growing pace, it is important to understand what we have learned in over three decades of research and what we still need...

Norway is generally characterized by a pervasive presence of digital services. It is currently undergoing a digital transformation across different domains, from daily life to public and private enterprises. In this introductory chapter, we first unpack the main drivers of digital transformation in...

To achieve energy efficiency and lower carbon emissions, building envelopes have become tighter and more insulated. These buildings must have mechanical ventilation with high efficient heat recovery to provide adequate indoor air quality using low energy in cold climates, and requirements for heat...
