Crystal plasticity models enhanced with coupled or uncoupled damage and fracture criteria give an opportunity to account for the role of microstructure in ductile fracture, most directly representing the local variations of stress and strain fields inside and between the grains, voids and particles. Some computationally efficient crystal plasticity, damage and fracture models have recently been ...

The conventional use of Laser-Induced Breakdown Spectroscopy (LIBS) for elemental analysis in high-density polyethylene (HDPE) limits the exploration of bond behavior in Physics and Chemistry. A suitable combination of process parameters, exceeding the bond dissociation threshold, enables LIBS to break HDPE bonds, facilitating laser-induced pyrolysis. However, understanding bond behavior post-breakage, ...

Kompetansenodens formål er ifølge Nærings- og fiskeridepartementet sitt oppdrag å styrke den maritime næringens kompetanse om særskilte utfordringer knyttet til skipsoperasjoner i polare farvann. I arbeidet med å styrke arktisk maritim kompetanse skal det tas utgangspunkt i innmeldte problemstillinger, utfordringer og behov fra aktører i skipsfartsnæringen. <p> <p>Polarkoden stiller krav til ...

Applying anti-icing fluid is the primary method of protecting aircraft surfaces from freezing precipitation before takeoff. This research's main objective is to deepen our understanding of the fluid failure mechanisms using the infrared thermography technique to observe the snow-fluid interactions. We use a laboratory-scale setup with an optical and infrared camera to study the interaction between ...

The presence of low-frequency power oscillations on the DC link and overlap-time both degrade the output power quality of single-phase current source inverters. This paper proposes a novel modulation technique that simultaneously mitigates the effects of both low-frequency power oscillations and overlap-time. By simultaneously addressing these issues, the proposed adaptive modulation technique ...

The open sea fish farm industry is under considerable pressure to ensure that fish farming represents a sustainable industry. Many challenges are present related to fish health due to fish lies, considerable density of fish with limited room to move, accelerations of the cage in large waves and needs to limit the use of antibiotic in the offshore environment. Much good work is done to increase ...

Residential buildings can actively participate in energy management strategies by integrating advanced metering infrastructure to have a reliable and stable distribution system. This paper introduces a novel home energy management system (HEMS) framework to minimize total electricity costs by optimizing the charging of an electric vehicle (EV). The methodology incorporates a non-intrusive load ...

Denne rapporten presenterer og drøfter implementering av større mengder solkraft i energisystemet i Longyearbyen. Solkraft er ikke det første man tenker på når man nevner Svalbard, men som absolutt viser seg å ha et potensial så langt nord. Mye på grunn av midnattssolen og kaldt klima. Det eksisterer allerede noen installasjoner av solkraft i og rundt Longyearbyen. Disse har blitt kartlagt og ...

This paper presents research on the changes in the properties of cement-bonded particleboard modified with particulate mixture (PM). PM replaced 4% of the binder (cement) and 4% of the filler (spruce chips). The cement-bonded particleboards were tested for physical (bulk density, swelling, linear expansion due to relative humidity changes) and mechanical properties (modulus of rupture and modulus ...
