Minimization of Surface Roughness and Temperature during Turning of Aluminum 6061 Using Response Surface Methodology and Desirability Function Analysis
(Peer reviewed; Journal article, 2022)Aluminum alloy is the second most abundant metal on Earth, known for its wide range of utilization in commercial goods due to its heat capacity and tensile strength. This study examines the effect of nose radius on the ... -
Minimizing the Cost of 5G Network Slice Broker
(Chapter, 2021)Network slicing is a key enabler of the fifth-generation (5G) of mobile networks. It allows creating multiple logical networks, i.e. network slices, with heterogeneous requirements over a common underlying infrastructure. ... -
Minimum Word Error Rate Training for Speech Separation
(Masteroppgave/UIS-TN-IDE/2019;, Master thesis, 2019-06-15)The cocktail party problem, also known as a single-channel multi-talker problem, is a significant challenge to enhance the performance of automatic speech recognition (ASR) systems. Most existing speech separation model ... -
Miscible CO2 flooding for EOR in the presence of natural gas components in displacing and displaced fluids
(Journal article; Peer reviewed, 2018-02)Carbon dioxide (CO2) flooding is a complicated process as it involves phase behavior. The objective of this work was to understand the mass transfer mechanisms during flooding with CO2 and CO2/C1/C3 (CO2/HC) based on ... -
The missing link in gravitational-wave astronomy: A summary of discoveries waiting in the decihertz range
(Peer reviewed; Journal article, 2021-04)Since 2015 the gravitational-wave observations of LIGO and Virgo have transformed our understanding of compact-object binaries. In the years to come, ground-based gravitational-wave observatories such as LIGO, Virgo, and ... -
The missing link of Rodinia break up in western South America: A petrographical, geochemical, and zircon Pb-Hf isotope study of the volcanosedimentary Chilla beds (Altiplano, Bolivia)
(Peer reviewed; Journal article, 2020)The assembly of Rodinia involved the collision of eastern Laurentia with southwestern Amazonia at ca. 1 Ga. The tectonostratigraphic record of the central Andes records a gap of ∼300 m.y. between 1000 Ma and 700 Ma, i.e., ... -
