Low power/high performance dynamic reconfigurable filter-design
(Master thesis, 2008)The main idea behind this thesis was to optimize the multipliers in a finite impulse response (FIR) filter. The project was chosen because digital filters are very common in digital signal processing and is an exciting ... -
Low Prevalence of Lactase Persistence in Bronze Age Europe Indicates Ongoing Strong Selection over the Last 3,000 Years
(Peer reviewed; Journal article, 2020)Lactase persistence (LP), the continued expression of lactase into adulthood, is the most strongly selected single gene trait over the last 10,000 years in multiple human populations. It has been posited that the primary ... -
Low Rank States with Bound Entanglement in a System of three qubits
(Master thesis, 2013)We have studied mixed quantum states in the system of three qubits with the property that all their partial transposes are positive; these are called PPT states. We classify a PPT state by the ranks of the state itself and ... -
Low Salinity Waterflooding in North Sea Reservoir Rocks:: An Experimental Investigation with emphasis on Wettability Effects
(Master thesis, 2010)For the last decades several laboratory tests and field tests on low salinity waterflooding have been done on oil bearing reservoirs. Overall the tests have shown an increased oil recovery with use of low salinity water. ... -
Low Salinity Waterflooding: An experimental investigation of the potential in the Frøy field in the North Sea
(Master thesis, 2010)In recent years, the focus on enhancing the oil recovery from oil fields has increased. This is because of falling oil reserves and the increased oil price. Because of this there is a big focus on enhancing oil recovery ... -
Low Serum Levels of 25-Hydroxyvitamin D Predict Hip Fracture in the Elderly: A NOREPOS Study
(Journal article; Peer reviewed, 2013)Background: Despite considerable interest, the relationship between circulating 25-hydroxyvitamin D and the risk of hip fracture is not fully established. Objective: The objective of the study was to study the association ... -
Low serum lipocalin-2 in pregnant women with systemic lupus erythematosus
(Peer reviewed; Journal article, 2023)OBJECTIVES: Systemic lupus erythematosus (SLE) pregnancies are considered high-risk due to risk of disease flare and pregnancy complications. A more in-depth understanding of the immunological alterations in SLE patients ... -
Low Short-Circuit Ratio Connection of Wind Power Plants
(Master thesis, 2015)Primary factor for the site selection during the planning process of the large modern wind farms is the wind climate, which is usually favorable at remote and offshore locations where the public grid is not particularly ... -
Low switching frequency modulation scheme for high power three level converters: FPGA based implementation
(Master thesis, 2013)The demand for electrical motors with high power ratings is increasing in different applications, especially in the offshore industry. The power rating of these motors can be raised by increasing the voltage at the motor ... -
Low temperature and low UV indexes correlated with peaks of influenza virus activity in Northern Europe during 2010-2018
(Journal article; Peer reviewed, 2019)With the increasing pace of global warming, it is important to understand the role of meteorological factors in influenza virus (IV) epidemics. In this study, we investigated the impact of temperature, UV index, humidity, ... -
Low Temperature Applications for CO2 Capture in Hydrogen Production
(Chapter, 2020)The recent development of the protonic membrane reformer (PMR) technology allows an energy efficient hydrogen production from natural gas. To liquefy and separate CO2 from the retentate gas of the PMR, various low temperature ... -
Low temperature carbon dioxide capture by PEI-modified mesoporous silica: synthesis and performance analysis
(Master thesis, 2021)Mesoporøse silisiumdioksydmidler ble fremstilt ved forskjellige synteseforhold ved konvensjonelle sol-gel-metoder. De stive sfæriske silisiumdioksidene med høyt overflateareal og høy porøsitet i smal distribusjon ble ... -
Low temperature drying and thermo-physical Properties of Brown seaweeds (Saccharina latissima)
(Chapter, 2017)The drying kinetics of brown seaweed Sacharina Latissima with and without blanching were investigated in temperature range between 10.0 and 38.0 °C. The drying process is more rapid for raw seaweeds. The effective moisture ... -
Low Temperature Plate Freezing of Fish on boats using R744 as Refrigerant and Cold Thermal Energy Storage
(Master thesis, 2018)The introduction of low temperature R744 freezing systems enables lower evaporating temperatures and faster freezing times, however, also a lower system efficiency (COP). This thesis will investigate how low temperature ... -
