Optimizing surge tank layout for highly flexible hydropower

Richter, Wolfgang; Vereide, Kaspar; Zenz, Gerald (Journal article; Peer reviewed, 2018)

This article considers high-head hydropower schemes and pumped storage schemes that usually are considered as flexible power plants. Surge tanks are the key structural element in the hydropower scheme for flexible operation ...

Optimizing the Capacity of Thermal Energy Storage in Industrial Clusters

Thombre, Mandar; Prakash, Sandeep; Knudsen, Brage Rugstad; Jäschke, Johannes (Chapter, 2020)

A key factor for energy-efficient industrial clusters is the recovery of waste heat. To this end, thermal energy storage (TES) is an appealing technology that facilitates dynamic heat integration between supplier and ...

Optimizing the configuration of a façade module for office buildings by means of integrated thermal and lighting simulations in a total energy perspective

Goia, Francesco; Haase, Matthias; Perino, Marco (Journal article; Peer reviewed, 2013)

The building enclosure plays a relevant role in the management of the energy flows in buildings and in the exploitation of solar energy at a building scale. An optimized configuration of the façade can contribute to reduce ...

Optimizing the performance of non-fading and fading networks using CSMA with joint transmitter and receiver sensing

Kaynia, Mariam; Øien, Geir Egil (Journal article; Peer reviewed, 2012)

We consider a mobile ad hoc network where packets belonging to specific transmitters arrive randomly in space and time according to a 3-D Poisson point process, and are upon arrival transmitted to their intended destinations ...

Optimizing the shape anisotropy of gold nanoparticles for enhanced light harvesting and photocatalytic applications

Antony, Jibin; Bandyopadhyay, Sulalit; Yang, Jia; Rønning, Magnus (Journal article; Peer reviewed, 2022)

Optimizing the Wood Value Chain in Northern Norway Taking Into Account National and Regional Economic Trade-Offs

Johansen, Ulf; Werner, Adrian; Nørstebø, Vibeke Stærkebye (Journal article; Peer reviewed, 2017)

As a consequence of past decades of extensive afforestation in Norway, mature forest volumes are increasing. National forestry politics call for sustainable and efficient resource usage and for increased regional processing. ...

Optimum scavenger concentrations for sonochemical nanoparticle synthesis

Hansen, Henrik Erring; Seland, Frode; Sunde, Svein; Burheim, Odne Stokke; Pollet, Bruno (Journal article; Peer reviewed, 2023)

Maintaining nanoparticle properties when scaling up a chemical synthesis is challenging due to the complex interplay between reducing agents and precursors. A sonochemical synthesis route does not require the addition of ...

Optimum solvent concentration to lower energy demands for CO2 capture in refinery cases

Hartono, Ardi; Knuutila, Hanna K (Journal article, 2022)

An open-access novel low-energy solvent HS-3 has been proposed and verified in the lab scale for post-combustion CO2 capture. The HS-3 solvent consists of a tertiary amine with a strong bicarbonate former and a primary ...

OptiqueVQS: a Visual Query System over Ontologies for Industry

Soylu, Ahmet; Kharlamov, Evgeny; Zheleznyakov, Dmitriy; Jimenez-Ruiz, Ernesto; Giese, Martin; Skjæveland, Martin G; Hovland, Dag; Schlatte, Rudolf; Brandt, Sebastian; Lie, Hallstein; Horrocks, Ian (Journal article; Peer reviewed, 2017)

An important application of semantic technologies in industry has been the formalisation of information models using OWL~2 ontologies and the use of RDF for storing and exchanging application data. Moreover, legacy data ...

Oral Assessment and Grade Integrity: A Case Study

Gynnild, Vidar (Journal article; Peer reviewed, 2015)

The construct of "grade integrity" refers to the degree to which awarded grades accurately represent the breadth and depth of academic achievement (Sadler, 2009b). This case study examines issues of grade integrity at ...
