Vacuum free energy, quark condensate shifts and magnetization in three-flavor chiral perturbation theory to O(𝑝6) in a uniform magnetic field
(Peer reviewed; Journal article, 2023)We study three-flavor QCD in a uniform magnetic field using chiral perturbation theory (χPT). We construct the vacuum free energy density, quark condensate shifts induced by the magnetic field and the renormalized magnetization ... -
Validating query execution plan estimates in MySQL
(Master thesis, 2010)The query optimizer in MySQL chooses from the available query execution plans by estimating the cost of execution for each plan. In this project, MySQL will be extended to record the actual cost of executing each query. ... -
Validation of a Developed Enterprise Architecture Framework for Digitalisation of Smart Cities: a Mixed‑Mode Approach
(Journal article; Peer reviewed, 2022)To support smart cities in aligning information technology (IT) and business strategies to achieve urban digitalization, this study aims to present an Enterprise Architecture Framework (EAF) to facilitate the digitalization ... -
Validation of Safety Metrics for Object Detectors in Autonomous Driving
(Chapter, 2024)Object detection consists in perceiving and locating instances of objects in multi-dimensional data, such as images or lidar scans. While object detection is a fundamental step in autonomous vehicles applications, it is ... -
Validation of stereo vision based liver surface reconstruction for image guided surgery
(Chapter, 2018)Image guided surgery systems aim to provide navigation to surgeons in order to improve accuracy and safety of the procedures. Through stereo reconstruction algorithms, it is possible to generate 3D surfaces intra-operatively ... -
Validation of the European visual field standards for driving: A driving simulator-based study
(Peer reviewed; Journal article, 2024)Purpose To determine whether we could establish evidence-based pass/fail criteria for perimetry in the context of the European visual field standards for driving. Methods This two-centre, cross-sectional study included ... -
Value co-creation and purchase intention in social commerce: The enabling role of word-of-mouth and trust
(Chapter, 2017)Social commerce combines commercial and social activities, and has managed in a very short period of time to attract the interest of researchers and practitioners. In this study we use theories of trust and value co-creation ... -
Value Co-Creation and Trust in Social Commerce: An fsQCA approach
(Chapter, 2017)This study aims to explain how value co-creation, between customers and companies, and key aspects of trust combine to influence customers’ purchase intentions in social commerce. Value co-creation is decomposed into two ... -
Value Modeling in the Agricultural Business Sector
(Master thesis, 2007)The growth of global market leads to that more and more organizations face drastic competitions in their industry area. The organizations whose products or services can attract a large amount of customers will take much ... -
Value Tensions in Telecare: An Explorative Case Study
(Chapter, 2018)We describe the results from a Norwegian case study of the attitudes of community-dwelling lung patients and health response center personnel toward a telecare service for such a patient group. The telecare service was ... -
Value-Added Services, Virtual Enterprises and Data Spaces Inspired Enterprise Architecture for Smart Cities
(Chapter, 2019)As a part of their digital transformation, municipalities across Europe have taken initiatives to support Open Data platforms and provide services leveraging on data. This challenges the traditional business driven IT ... -
Variance-Based Exploration for Learning Model Predictive Control
(Peer reviewed; Journal article, 2023)The combination of model predictive control (MPC) and learning methods has been gaining increasing attention as a tool to control systems that may be difficult to model. Using MPC as a function approximator in reinforcement ... -
Variational Anisotropic Gradient-Domain Image Processing
(Peer reviewed; Journal article, 2021)Gradient-domain image processing is a technique where, instead of operating directly on the image pixel values, the gradient of the image is computed and processed. The resulting image is obtained by reintegrating the ... -
Variational Approach for Capsule Video Frame Interpolation
(Journal article; Peer reviewed, 2018)Capsule video endoscopy, which uses a wireless camera to visualize the digestive tract, is emerging as an alternative to traditional colonoscopy. Colonoscopy is considered as the gold standard for visualizing the colon and ... -
Variational based smoke removal in laparoscopic images
(Journal article; Peer reviewed, 2018)Background In laparoscopic surgery, image quality can be severely degraded by surgical smoke, which not only introduces errors for the image processing algorithms (used in image guided surgery), but also reduces the ... -
Variational Inference over Nonstationary Data Streams for Exponential Family Models
(Peer reviewed; Journal article, 2020)In many modern data analysis problems, the available data is not static but, instead, comes in a streaming fashion. Performing Bayesian inference on a data stream is challenging for several reasons. First, it requires ... -
The VAROS Synthetic Underwater Data Set: Towards realistic multi-sensor underwater data with ground truth
(Peer reviewed; Journal article, 2021)Underwater visual perception requires being able to deal with bad and rapidly varying illumination and with reduced visibility due to water turbidity. The verification of such algorithms is crucial for safe and efficient ... -
The vascular occlusion test using multispectral imaging: a validation study
(Peer reviewed; Journal article, 2020)Multispectral imaging (MSI) is a new, non-invasive method to continuously measure oxygenation and microcirculatory perfusion, but has limitedly been validated in healthy volunteers. The present study aimed to validate the ... -
