Datasets for grey-box model identification from representative archetypes of apartment blocks in Norway
(SINTEF Proceedings;5, Chapter; Peer reviewed; Conference object, 2020)Grey-box models combine a relatively simple physical description of the building with a data-driven inference of key parameters and are often used for this purpose. A challenge with grey-box models is that the model ... -
Defining Ship Autonomy by Characteristic Factors
(SINTEF Proceedings;3, Chapter; Peer reviewed; Conference object, 2019)Several papers have proposed ways to define levels of autonomy (LOA), i.e. how responsibility is shared between an automation system and a human when the automation system to some degree can operate independently of the ... -
Demand-controlled ventilation in schools: Influence of base ventilation rates on subjective symptoms, perceived indoor environment and young adults' learning performance
(SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)The ventilation airflow rates in a demand-controlled ventilation strategy typically vary between a base (Vmin) and a maximum ventilation rate (Vmax). Classrooms have relatively short but intense hours of occupancy and a ... -
Description of the Work and Preliminary Results of the Ac2ocem Project in Facilitating Carbon Capture Technology in the Cement Industry Using Oxyfuel Combustion
(SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)The Paris agreement compels CO2 intensive industries, such as the cement industry to significantly decrease the CO2 emissions. The source of the CO2 emissions from the cement industry is related to the calcination and the ... -
Design and Multi-Objective Optimization of Co2 Value Chains for a Net-Negative Waste To Energy Sector: A Swiss Case Study
(SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)This study investigates the optimal design of CO2 value chains aimed at decarbonizing the waste to energy (WtE) sector on a national scale and presents the case study of Switzerland. Switzerland has 30 WtE plants that ... -
Design Dilemmas in Mental Hospital Architecture
(SINTEF Proceedings;8, Chapter; Peer reviewed; Conference object, 2021)Objective – The paper identifies dilemmas facing architects, planners and medical professionals in the process of designing a new psychiatric facility. Background – Rarely any other type of public building has had such a ... -
Design for psychiatric patients: the complexities of therapeutic architecture decision-making
(SINTEF Proceedings;8, Chapter; Peer reviewed; Conference object, 2021)Objective - The research set to identify integrated methodologies for the design, planning and evaluation of psychiatric facilities in the community. Background - De-institutionalisation resulted in care delivered in the ... -
Development and Application of a Ventilation System Based on Vertical Descendent Confluent Jets
(SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)This paper presents the development and application of a ventilation system based on vertical confluent jets. The thermal comfort and indoor air quality levels, Air Distribution Index and energy consumption are evaluated ... -
Development of GPU Parallel Multiphase flow solver for turbulent slurry flows in cyclone
(SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)The development of GPU parallelized unstructured multiphase solver and its application in predicting turbulent swirling flow of slurries inside cyclones is presented. Algebraic slip mixture model (ASM) is modified with ... -
Development of Silica Sodalite With Enhanced Porosity via Topotactic Synthesis for Pre Combustion Co2 Capture
(SINTEF Proceedings;4, Chapter; Conference object; Peer reviewed, 2019)Topotactic conversion of layered silicates is reported to yield sodalite with enhanced frameworks, chemical compositions and predictable outcomes. Traditional hydrothermal synthesis results in sodalite with occluded matter ... -
Digital twin of the Live-In Lab Testbed KTH: development and calibration
