NOM removal in drinking water treatment using dead-end ceramic microfiltration: Assessment of coagulation/flocculation pretreatment
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:3, Doctoral thesis, 2011)In Nordic countries, surface water is a common source for potable water production. Such waters are often characterised by high Natural Organic Matter (NOM) content, resulting in high colour, very low turbidity, low ... -
Non-Destructive Inspection of Polymer Composite Pipelines
(Master thesis, 2022)Rør laget av fiberforsterket komposittplast (FRP) har potensial til å erstatte metalliske i olje- og gassindustrien, grunnet deres fordelaktige egenskaper som lav vekt, høy styrke og motstand mot korrosjon. En stor hindringen ... -
Non-Linear Finite Element Analysis of Sheets with Integrated Patterns - Identification of the Significant Mechanisms contributing to Non-Linear Behavior
(Master thesis, 2018)By cutting specific patterns in thin sheets of material it is possible to acquire a high degree of compliance in and out of the plane. These structures, called flexure patterns, are often applied in situations causing large ... -
Nonlinear Mechanical Vibrations: The Effect of Gaps
(Master thesis, 2018)In this report, the vibration properties of nonlinear mechanical joints have been explored. The nonlinearity is due to a clearance gap in the joint, which may arise intentionally in design or through wear and tear. How gap ... -
Nonlinear state and parameter estimation of a gas-liquid cylindrical cyclone
(Chapter, 2018)— New offshore oil and gas discoveries are located at deep waters with long tie-back distances. Development of such fields require compact gas-liquid separation technologies. Efficient operation of such separators require ... -
