Short-term heat stress in situ reduces net photosynthesis and alters metabolite composition in the arctic poppy Papaver dahlianum
(Master thesis, 2016)Climate change is increasing the mean summer temperature in the Arctic and with that the probability of extreme climatic events including heat waves. An increase in heat waves may cause increased stress in a number of ... -
Short-term hydropower optimization in the day-ahead market using a nonlinear stochastic programming model
(Peer reviewed; Journal article, 2023)Hydropower producers participate in electricity markets by providing bids in market auctions, typically day-ahead. Making good bids that obey all market rules and consider uncertain prices for large, interconnected hydropower ... -
Short-term hydropower scheduling in congested areas: A novel approach employing DC power flow and grid limitations
(Master thesis, 2022)Denne masteroppgaven evaluerer virkningen av å inkludere kraftflytlikninger i den kortsiktige vannkraftplanleggingen. Forskningen og arbeidet utføres på en egenutviklet optimaliseringsmodell i et område med begrenset ... -

Short-Term Hydrothermal Scheduling with Solar and Wind Farms Using Second-Order Cone Optimization with Chance-Box Constraints
(Peer reviewed; Journal article, 2021)Short-Term Hydrothermal Scheduling (STHS) is a classic problem in power system operation where the aim is to decide the dispatch of both thermal and hydroelectric units. This problem is complex due to its non-linear ... -
Short-term Iceberg Drift Estimation and Prediction
(Doctoral theses at NTNU;2018:186, Doctoral thesis, 2018)Short-term iceberg drift forecast is part of the Ice Management framework, which is a key component of the International Standard, ISO 19906 specifying requirements and guidance for the design, construction, transportation, ... -
The short-term impact of methylprednisolone on patient-reported sleep in patients with advanced cancer in a randomized, placebo-controlled, double-blind trial
(Peer reviewed; Journal article, 2020)Purpose: Although corticosteroids are frequently used in patients with advanced cancer, few studies have examined the impact of these drugs on patient-reported sleep. We aimed to examine the short-term impact of ... -
The short-term impact of terrorism on public mental health: an emergency primary care approach
(Journal article; Peer reviewed, 2023)Background Terrorist attacks commonly have mental health consequences for those directly affected. Existing research is, however, divided when it comes to how and whether terrorist attacks affect the general population’s ... -
Short-term inflow forecasting in a dam-regulated river in Southwest Norway using causal variational mode decomposition
(Peer reviewed; Journal article, 2023)Climate change affects patterns and uncertainties associated with river water regimes, which significantly impact hydropower generation and reservoir storage operation. Hence, reliable and accurate short-term inflow ... -
Short-Term Intermittency of Solar Irradiance in Southern Norway
(Chapter, 2014)The temporal variability of solar irradiance at small time scales ranging from 1 second to 2 minutes was studied to characterize the short term fluctuations in irradiance at high latitudes. The change in irradiance at time ... -
Short-Term Memory Effects in Subjective Image Quality Assessment of Natural Images
(Journal article; Peer reviewed, 2019)In this paper we discuss the influence of short-term memory in judging image quality of natural images. For this, a category judgement experiment with 15 observers has been carried out on a set of natural images. To analyze ... -
A short-term musical training affects implicit emotion regulation only in behaviour but not in brain activity
(Journal article; Peer reviewed, 2021)Background: In everyday life, negative emotions can be implicitly regulated by positive stimuli, without any conscious cognitive engagement; however, the effects of such implicit regulation on mood and related neuro-mechanisms, ... -
Short-TERM Neuromuscular Electrical Stimulation Training of the Tibialis Anterior Did Not Improve Strength and Motor Function in Facioscapulohumeral Muscular Dystrophy Patients
(Journal article; Peer reviewed, 2017)Objective: The aim of this study was to investigate the effects on motor function, muscle strength, and endurance of short-term neuromuscular electrical stimulation training of the tibialis anterior muscles in patients ... -
Short-term outcome after open-heart surgery for severe chronic rheumatic heart disease in a low-income country, with comparison with an historical control group: An observational study
(Peer reviewed; Journal article, 2021)Objectives Rheumatic heart disease (RHD) is a major burden in low-income and middle-income countries (LMICs). Cardiac surgery is the only curative treatment. Little is known about patients with severe chronic RHD operated ... -
