A probabilistic approach to the value chain of underground iron ore mining: From deposit to product
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:65, Doctoral thesis, 2005)Mining activities will eventually deplete any deposit. In a sustainability perspective, the deposit should therefore be utilised optimally during production. A prerequisite to achieve this is the deliberate and consistent ... -
A probabilistic-based methodology for evaluation of timber facade constructions - The Performance to withstand biodeterioration
(Doctoral theses at NTNU;2018:69, Doctoral thesis, 2018)Mould and decay are biodeterioration phenomena that jeopardize the integrity, functionality and durability of timber façade constructions. Accounting for them during the design stage is crucial for the prevention of social ... -

A study of ageing and degradation of asphalt pavements on low volume roads
(Dr. ingeniøravhandling, 0809-103X; 2000:49, Doctoral thesis, 2000)An important objective with this research work has been to get more knowledge about mix design and maintenance of low volume roads with asphalt pavements in Norway. A literature review on bitumen, filler, rheology and ... -
A Study of Load Responses towards the Pavement Edge
(Dr.ingeniøravhandling, 0809-103X; 2001:118, Doctoral thesis, 2002)A major part of the national and county road network in Norway consists of two-lane roads with relatively narrow shoulders. The width of the roadway is limited, forcing heavy trucks to drive close to the pavement edge. ... -
A Study of some Factors in Mechanistic Railway Track Design
(Dr. ingeniøravhandling, 0809-103X; 2002:54, Doctoral thesis, 2002)This thesis is composed of three main parts: The first part that uses classic track models as a basis for further developments, the second part that deals with constitutive behaviour of granular materials and the third ... -
A Study of the Ultrasonic Measurements for Logging Behind a Steel Pipe: Expanding the proessing to improve the differentiation between heavy fluids and light solids
(Doctoral theses at NTNU;2019:375, Doctoral thesis, 2020)In petroleum applications using acoustic wave theory, the most used practice can be found in borehole geophysical methods, where acoustic logging has long been the foremost source for cement evaluation. Due to stricter ... -
A Study of Ultra-Low Temperature Application for Fish Freezing and Storing
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:128, Doctoral thesis, 2014)This work was performed in order to get information about the economic benefit of maintaining the quality and increasing the shelf-life of fish using ultra-low temperature (between –30.0 and –85.0 °C). The scope of the ... -
A Systems Engineering Approach to the Design of Manufacturing Systems
(Doctoral thesis, 2014)Rising competitiveness in the 21st century and the increasing complexity of manufacturing systems demand the refinement of manufacturing system design practices by investing more effort during the planning and design ... -
