Multilevel CC2 and CCSD in Reduced Orbital Spaces: Electronic Excitations in Large Molecular Systems
(Peer reviewed; Journal article, 2021)We present efficient implementations of the multilevel CC2 (MLCC2) and multilevel CCSD (MLCCSD) models. As the system size increases, MLCC2 and MLCCSD exhibit the scaling of the lower-level coupled cluster model. To treat ... -
Multilevel CC2 and CCSD Methods with Correlated Natural Transition Orbital
(Peer reviewed; Journal article, 2019)In the multilevel coupled cluster approach, an active orbital space is treated at a higher level of coupled cluster theory than the remaining inactive orbitals. We introduce the multilevel CC2 method where CC2 is used for ... -
Multilevel considerations for sustainability management
(Doctoral theses at NTNU;2023:342, Doctoral thesis, 2023)This thesis investigates how the concept of business models for sustainability (BMfS) supports and enables sustainability management in organizations, along with how the concept can bridge organizational and societal system ... -
Multilevel Converters for a 10 MW, 100 kV Transformer-less Offshore Wind Generator System
(Master thesis, 2012)The size of offshore wind generators is increasing, and the trend is moving towards full converter gear-less solutions with permanent magnet synchronous generators (PMSG). The nacelle weight reduction is a key design ... -
A Multilevel Convolutional Recurrent Neural Network for Blade Icing Detection of Wind Turbine
(Peer reviewed; Journal article, 2021)Blade icing detection becomes increasingly significant as it can avoid revenue loss and power degradation. Conventional methods are usually limited by additional costs, and model-driven methods heavily depend on prior ... -
Multilevel coupled cluster methods for large molecular systems
(Doctoral theses at NTNU;2020:240, Doctoral thesis, 2020)The coupled cluster hierarchy of models can be used to accurately describe electronic excitations in molecular systems. However, the standard coupled cluster models are expensive and their cost severely limits the size of ... -
Multilevel coupled cluster theory: Development, implementation and application of multilevel coupled cluster theory for core and valence excited states
(Doctoral thesis at NTNU;2016:267, Doctoral thesis, 2016)This thesis consist of seven papers and an introduction describing the ongoing development and applications of multilevel coupled cluster theory. Coupled cluster theory is one of the most accurate, but also one of the ... -
Multilevel Fusion of Multispectral Images to Detect the Artificially Ripened Banana
(Journal article, 2023) -
Multilevel Maxwell-Bloch simulations in inhomogeneously broadened media
(Journal article; Peer reviewed, 2011)A compact numerical method for simulating ultrafast pulse interaction with inhomogeneously broadened multi-level media is reported. We use a low-dispersion pseudospectral scheme with fourth order time stepping for Maxwell’s ... -
Multilevel networks for climate change adaptation – what works?
(Journal article; Peer reviewed, 2018)Purpose The paper aims to compare and evaluate two Norwegian municipal networks for climate change adaptation, to see how such networks should be initiated and implemented as a means of achieving adaptation measures within ... -
Multilevel Power Electronic Converters for Electrical motor Drives
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:62, Doctoral thesis, 2005)Power electronic converters are widely used in industrial power conversion systems both for utility and drives applications. As the power level increases, the voltage level is increased accordingly to obtain satisfactory ... -
Multilevel Screening of Ionic Liquid Absorbents for Simultaneous Removal of CO2 and H2S from Natural Gas
(Peer reviewed; Journal article, 2020)For the selection of practically attractive ionic liquids (ILs) as absorbents for simultaneous CO2 and H2S removal from natural gas (NG), a multilevel screening method combining Henry′s law constant (H) and vapor–liquid ... -
Multilingual Audio-Visual Smartphone Dataset and Evaluation
(Peer reviewed; Journal article, 2021)Smartphones have been employed with biometric-based verification systems to provide security in highly sensitive applications. Audio-visual biometrics are getting popular due to their usability, and also it will be challenging ... -
Multilingual lexical transfer challenges monolingual educational norms: not quite!
(Peer reviewed; Journal article, 2021)Foreign language learners frequently use words from their previously acquired language(s) in the target language, especially if these languages are related (Ringbom, Håkan. 2001. Lexical transfer in L3 production. In Jasone ... -
Multilingual News Article Classification
(Master thesis, 2016)News is an ever-growing and global resource, reliant on robust distribution networks to spread information. This thesis investigates how exploiting semantic, contextual and ontological information may form a basis for a ... -
The Multilingual Picture Database
(Peer reviewed; Journal article, 2022)The growing interdisciplinary research field of psycholinguistics is in constant need of new and up-to-date tools which will allow researchers to answer complex questions, but also expand on languages other than English, ... -
Multilingual Poetry Generation
(Master thesis, 2019)I krysset mellom Natural Language Processing and Computational Creativity er diktgenerering en sammensatt oppgave, delvis på grunn av de forskjellige formene den kan ta og subjektiviteten til evalueringen. På grunn av deres ... -
Multilingual Review-aware Deep Recommender System via Aspect-based Sentiment Analysis
