...socio-economic role by contributing to employment and the economy at large. The key prerequisites are a high productivity and a strong competitive edge. One of the ways to obtain and maintain a competitive edge is if (small and medium-sized) companies apply new knowledge and new technologies. However, a key barrier...
...state-of-the art review on relevant existing studies and tools that could be serve as inspiration for tool development and guidelines in the EE Settlement project. The report summarizes the methodological choices and the outcome of two Austrian projects, ZERsiedelt and ELAS, which are considered as a basis for...
...to accurately represent horizontal and multilateral wells, but can also be used to create volumetric representations of fracture networks. Boundary alignment of cell faces is introduced to accurately preserve geological features such as layers, fractures, faults, and/or pinchouts. Prescribed geometric...
...system has also been studied by high resolution transmission electron microscopy (TEM). 80 nm Al and 2–3 nm C were inactive, and would not allow hydrogen (H) desorption from NaAlH4. 30 nm Cr, 25 nm Fe, 30 nm Ni, and 25 nm Pd showed activity, but with weak kinetics of only ca. 1 wt.% H/hour. The NaAlH4 + 0...
Petroleum Safety Authority Norway (PSA) with the theme of human-centred design and human-machine interfaces in the development and implementation of autonomous systems in drilling and wells. The report summarises the review and findings from the project. Through the project, we have seen that automation...
...stability of a blend of 3-amino-1-propanol (3A1P) and 1-(2-hydroxyethyl)pyrrolidine [1-(2HE)PRLD] was studied. The chemical stability tests were conducted both in batch and cycled systems using various oxygen and NOx concentrations, additives (iron), and temperatures. In the thermal degradation experiments...
...design is given. The low-cost processing sequence is presented and each processing step is explained in detail. The processing sequence is also compared to other low-cost fabrication techniques. Results from the electrical probing and mechanical strength test are given. The results demonstrate that...
...energy efficiency in school building retrofitting, and at the same time focus on the importance of healthy indoor environments. This report is meant to ease the work for people involved in school retrofitting by presenting existing knowledge, theories and experiences, concerning these topics. The report...
