What turns us off about green and blue spaces in cities? Understanding perceived problems and unpleasant experiences for more just urban planning, design and management

People and Nature, EarlyView.
Abstract The planning, design and management of urban green and blue spaces necessitate trade‐offs between these spaces' many benefits and their drawbacks, but knowledge of perceived problems and unpleasant experiences in urban green and blue spaces remains limited.

Design and Implementation of a Simulation System for Vertical and Directional Drilling in an Autonomous Miniature Drilling Rig

, 2020
Digitalisering og automatisering av prosesser har i flere bransjer hatt stor påvirkning, særlig over de siste årene. Selv om R&D har utviklet en rekke før manuelle prosesser til å nå bli autonome, gjelder dette fortsatt ikke for oljedrilling. Dette har ført til at the Society of Petroleum Engineers (SPE) opprettet the Drilling System Automation ...

Liquid‐Processed 2D Aromatic Amorphous Carbon: Defect Engineering and Universal Transport Scaling

Small, EarlyView.
Liquid‐processed graphene oxide (GO) thin films undergo a controllable crystalline–to–amorphous transition driven by thermal quenching. By kinetically tuning oxygen‐driven defect formation during reduction, scalable 2D aromatic amorphous carbon phases are stabilized, directly linking nanoscale disorder and defect topology to electronic transport ...
