Evaluation of mitigation measures for Atlantic salmon and brown trout at hydropower plants and their prospect as selective agents
(Doctoral dissertations at University of Agder;no. 314, Doctoral thesis, 2021)Renewable energy contributes towards the world`s growing energy demands and urgent need for mitigating climate change. However, these renewable sources of energy may have localized, detrimental environmental effects. For ... -
Atmospheric brightening counteracts warming-induced delays in autumn phenology of temperate trees in Europe
(Peer reviewed; Journal article, 2021)Aim Ongoing climate warming has been widely reported to delay autumn phenology, which in turn impacts carbon, water, energy and nutrient balances at regional and global scales. However, the underlying mechanisms of autumn ... -
Tracking of Quantized Signals Based on Online Kernel Regression
(Peer reviewed; Journal article, 2021)Kernel-based approaches have achieved noticeable success as non-parametric regression methods under the framework of stochastic optimization. However, most of the kernel-based methods in the literature are not suitable to ... -
Parameter Identification of Fractional-Order LTI Systems using Modulating Functions with Memory Reduction
(Chapter, 2021)The parameter estimation problem of a linear time-invariant fractional-order system is investigated by means of the modulating function method. Based on the assumption of known model structure and derivative orders, the ... -
Performance Analysis of Alamouti Coded OFDM Systems over Wideband MIMO Car-to-Car Channels Correlated in Time and Space
(Chapter, 2014)In this paper, the performance of Alamouti coded orthogonal frequency division multiplexing (OFDM) systems over car-to-car (C2C) fading channels correlated in time and space is analyzed. Taking different geometrical ... -
A Trajectory-Driven SIMO mm-Wave Channel Model for a Moving Point Scatterer
(Chapter, 2021)In this paper, we propose a trajectory-based three-dimensional (3D) non-stationary channel model for a millimeter wave (mm-Wave) single-input multiple-output (SIMO) system. The proposed channel model is designed to capture ... -
Data-Driven Pump Scheduling for Cost Minimization in Water Networks
(Chapter, 2021)Pumps consume a significant amount of energy in a water distribution network (WDN). With the emergence of dynamic energy cost, the pump scheduling as per user demand is a computationally challenging task. Computing the ... -
Incidence of persistent contaminants through blue mussels biomonitoring from Flekkefjord fjord and their relevance to food safety
(Peer reviewed; Journal article, 2020)Dredging activities can lead to the re-suspension of contaminated sediments, resulting in a potential hazard for the whole ecosystem and also for human health. Six-month active biomonitoring was performed in order to monitor ... -
