Downstream migrating fish face injury and mortality risks from turbines and hydraulic structures due to cavitation, pressure drops, blade strikes, and hydraulic shear. Waterproof autonomous sensors measured these risks by tracking pressure changes and strike events. The study, conducted at the...

This fourth and final version (version 4.0) of the ZEN definition guideline report builds upon V1.0, V2.0 and V3.0 of the ZEN definition guideline reports and a series of ZEN definition reports. This report highlights that an nZEN balance is required instead of point allocation in the GHG emissions...

Denne fjerde og siste utgaven (versjon 4.0) av ZEN-definisjonsveilederen bygger på v.1.0, v.2.0 og v.3.0 av ZEN-definisjonsveilederne, samt en rekke andre ZEN-definisjonsrapporter. Denne veilederen fremnever at en netto nullutslippsbalanse er krevd istedenfor poengallokering i klimagass...

Nyhavna er et område i Trondheim som per i dag hovedsakelig brukes til industrielle formål, men som skal utvikles til et attraktivt boligområde i de kommende tiårene. Ifølge kvalitetsprogrammet skal området ikke føre til økt energibehov, effektbehov eller klimagassutslipp i byen; og bygningene og...

This document outlines the definition, key performance indicators (KPI), and assessment criteria for the Research Centre on Zero Emission Neighbourhoods in Smart Cities (ZEN research centre). This fifth version of the ZEN definition builds upon previous versions of the ZEN definition report and the...

Denne rapporten beskriver definisjoner, nøkkelindikatorer og vurderingskriterier som benyttes i Forskningssenter for nullutslippsområder i smarte byer (ZEN-senteret). Versjon 5.0 bygger på tidligere versjoner av ZEN-definisjonsrapporten og serien av ZEN definisjonsveiledere (1). Versjon 5.0 gir...

The applied model consists of a three step FE simulation procedure including elasticplasticstress analysis, diffusion analysis and finally elastic-plastic stress analysiswith hydrogen influenced cohesive elements implemented in the crack path. The applied FE code is ABAQUS Standard 6.5Constant load...

In this paper, we present the calibration setup, method, and results for a set of strain gauges installed on the trailing edge of the runner blades of a model Francis turbine. The calibration work is done as a step in the HydroFlex project, with the goal of taking experimental data to validate...

Author keywords Indexed keywords SciVal Topics Funding details Abstract Offshore wind energy is growing continuously and already represents 12.7% of the total wind energy installed in Europe. However, due to the variable and intermittent characteristics of this source and the...

Structure-preserving machine learning has recently become an active area of research. Popular models in this field, such as Hamiltonian neural networks, would typically require data on the system’s momentum and this can be a limitation of the approach. Instead, we consider a method for learning...
