...carbon and nitrogen in liquid silicon have been studied experimentally. High purity silicon was melted in silicon nitride crucibles under an Ar atmosphere with a graphite slab inserted in the crucible prior to melting as a carbon source. The system was thus simultaneously equilibrated with Si3N4 and SiC...
...shipbuilding excellence are cutting edge technology and proactive team behaviour to effectively share & combine resources and knowledge to quickly handle disturbances. That said, the average cost overrun of frequent changes in the industry is high, and with steadily increasing cost constraints in the Norwegian...
...impedance, making the transducers challenging to drive with conventional electronics and cables. Air-backed transducers with electrical tuning circuitry and cable assembly were made using the piezoelectric materials Pz24, Pz27, and Pz29. Pz24 is a hard PZT, with dielectric constant of 240, the other materials...
...for a Norwegian carbon capture and storage demonstration will result in the establishment of a central CO2 hub on the west-coast of Norway and storage on the Norwegian Continental Shelf. This development may continue towards a large-scale operation involving European CO2 and CO2 EOR operation. To this end...
...solar heating and daylighting) and to avoid cooling load, and to find the best strategy (i.e. to optimize the overall performance) for controlling shading devices is not trivial. Different control strategies for the activation of the shading devices (venetian blinds) are simulated, and their performance...
...optimization (PSO), and deep convolutional networks. The process starts by removing noise and errors from the images database by the local outlier factor (LOF) algorithm. Next, the algorithm studies different correlations from the set of images in the database. This creates homogeneous, and similar clusters...
...phase diagrams and secondary phase formation. In the present work, the stand alone Alstruc model, a microsegregation model for industrial multicomponent aluminium alloys, is coupled with the continuum model ALSIM which calculates the macroscopic transport of mass, enthalpy, momentum, and solutes as well...
...a <110>-oriented mono-like silicon ingot grown from monocrystalline seeds. These areas are related to dislocation clusters forming at seed junctions and several generation mechanisms are discussed. Dislocations generated due to physical contact between seeds could only be completely avoided by introducing...
In this work, an experimental study was carried out with the aim of linking static and dynamic stiffness of shales. Four fully saturated field shales were tested. The experiments were carried out in SINTEF's low-frequency cell. The measurements included undrained quasi-static loading cycles from which...
Instrumented Systems (SIS), which pioneered modern approaches to industrial control and automation systems (ICAS) security in the oil and gas industry. The basic conceptual advance of the SeSa approach, combining security and safety in the manufacturing of ICAS systems, is today prolonged by an ongoing attempt...
...undergo digitalization and digital transformation (DT) simultaneously; in itself, either is daunting. For 15 months, we followed the ongoing digitalization and DT activities at a maritime company with over 3700 employees through a qualitative analysis of 20 interviews, a workshop, and several documents....
