Efficient extracellular vesicle isolation by combining cell media modifications, ultrafiltration, and size-exclusion chromatography
(Peer reviewed; Journal article, 2018-09-27)Extracellular vesicles (EVs) are a heterogeneous population of biological particles released by cells. They represent an attractive source of potential biomarkers for early detection of diseases such as cancer. However, ... -
Efficient extraction of small microplastic particles from rat feed and feces for quantification
(Journal article; Peer reviewed, 2023)To date, microplastic is ubiquitously encountered in the environment. Studies analyzing microplastic in terrestrial ecosystems, including animal feces and feed, are few. Microplastic quantification method validation and ... -
Efficient Global Minimization for the Multiphase Chan-Vese Model of Image Segmentation
(Peer reviewed; Journal article, 2009)The Mumford-Shah model is an important variational image segmentation model. A popular multiphase level set approach, the Chan-Vese model, was developed as a numerical realization by representing the phases by several ... -
Efficient global minimization methods for variational problems in imaging and vision
(Doctoral thesis, 2011-08-19)Energy minimization has become one of the most important paradigms for formulating image processing and computer vision problems in a mathematical language. Energy minimization models have been developed in both the ... -
Efficient hash maps to G2 on BLS curves
(Journal article; Peer reviewed, 2022)When a pairing e:G1×G2→GT, on an elliptic curve E defined over a finite field Fq, is exploited for an identity-based protocol, there is often the need to hash binary strings into G1 and G2. Traditionally, if E admits a ... -
Efficient implementation of LowMC in HElib
(Master thesis, 2018-06-19)LowMC is a symmetric block cipher designed for fully homomorphic encryption. This thesis focuses on Martin Albrecht’s implementation of the cipher in the FHE library HElib, and how his implementation can be improved when ... -
Efficient Minimum Weight Vertex Cover Heuristics Using Graph Neural Networks
(Journal article; Peer reviewed, 2022)Minimum weighted vertex cover is the NP-hard graph problem of choosing a subset of vertices incident to all edges such that the sum of the weights of the chosen vertices is minimum. Previous efforts for solving this in ... -
Efficient Monte Carlo simulation reveals significant multiple scattering errors in underwater angular scattering measurements
(Journal article; Peer reviewed, 2022)Multiple scattering can severely affect the accuracy of optical instrumentation. Variance reduction methods have been implemented to improve a Monte Carlo model developed to simulate volume scattering functions measured ... -
An efficient software framework for performing industrial risk assessment of leakage for geological storage of CO2
(Peer reviewed; Journal article, 2011)In response to anthropogenic CO2 emissions, geological storage has emerged as a practical and scalable bridge technology while renewables and other environmentally friendly energy production methods mature. While an ... -
Efficient Solvers for Nonstandard Models for Flow and Transport in Unsaturated Porous Media
(Journal article; Peer reviewed, 2022)We study several iterative methods for fully coupled flow and reactive transport in porous media. The resulting mathematical model is a coupled, nonlinear evolution system. The flow model component builds on the Richards ... -
Efficient solvers for Richards' equation
(Master thesis, 2023-01-20)In this thesis we have sought to solve Richards’ equation. In time we applied a backward Euler discretization and in space we used a continuous Galerkin finite element discretization. The focal point was how to efficiently ... -
An efficient training scheme for supermodels
(Peer reviewed; Journal article, 2017-06-28)Weather and climate models have improved steadily over time as witnessed by objective skill scores, although significant model errors remain. Given these imperfect models, predictions might be improved by combining them ... -
Efficient vasculature investment in tissues can be determined without global information
(Journal article; Peer reviewed, 2020)Cells are the fundamental building blocks of organs and tissues. Information and mass flow through cellular contacts in these structures is vital for the orchestration of organ function. Constraints imposed by packing and ... -
Efficient water table evolution discretization using domain transformation
(Peer reviewed; Journal article, 2017-02)Domain transformation methods are useful techniques for solving problems on non-stationary domains. In this work, we consider the evolution of the water table in an unconfined aquifer. This nonlinear, time-dependent problem ... -

Effisiens i terminmarkedet for laks: En empirisk analyse av Fish Pool
(Master thesis, 2018-06-19)Derivatbørsen Fish Pool ble etablert i 2006, og er den eneste internasjonalt regulert markedsplassen for kjøp og salg av terminkontrakter for laks. Finansielle kontrakter gir markedsaktørene en mulighet til å risikostyre ... -
Effort-reward imbalance: A risk factor for exposure to workplace bullying
(Peer reviewed; Journal article, 2019-02-25)Previous research shows that work environment factors are important antecedents of workplace bullying (WB), because of the stress they may induce. While previous studies have typically used Karasek’s Job Demand-Control ... -
Efforts in Europe for Data-Driven Improvement of Education–A Review of Learning Analytics Research in Six Countries
