Formulating the multi object tracking problem as a network flow optimization problem is a popular choice. The weights of such network flow problem can be learnt efficiently from training data using a recently introduced concept called Generalized Graph Differences (GGD). This allows a general tracker implementation to be specialized to drone videos by training it on the VisDrone dataset. Two modif
In this article I present some of my recent research on scaling limits in two-dimensional eigenvalue ensembles.
With the increasing number of IoT devices deployed, the problem of switching ownership of devices is becoming more apparent. Especially, there is a need for transfer protocols not only addressing a single unit ownership transfer but secure transfer of a complete infrastructure of IoT units including also resource constraint devices. In this paper we present our novel ownership transfer protocol fo
Fast and accurate homography estimation is essential to many computer vision applications, including scene degenerate cases and planarity detection. Such cases arise naturally in man-made environments, and failure to handle them will result in poor positioning estimates. Most modern day consumer cameras are affected by some level of radial distortion, which must be compensated for in order to get
This chapter uses the term adaption in the sense of how a regionally based, popular culture phenomenon has nurtured structural economic transformation. The chapter elaborates a critical examination of the comparative popularity of Nordic noir, asking whether the two long-running film and television crime franchises Wallander (Wallander, (1994–2016) and The Bridge (Bron/Broen, 2011–2018) have been
Background: Prostate-specific membrane antigen (PSMA) radiotracers such as [18F]PSMA-1007 used with positron emission tomography-computed tomography (PET-CT) is promising for initial staging and detection of recurrent disease in prostate cancer patients. The block-sequential regularization expectation maximization algorithm (BSREM) is a new PET reconstruction algorithm, which provides higher image
A deeper knowledge of the architecture of the peripheral nerve with three-dimensional (3D) imaging of the nerve tissue at the sub-cellular scale may contribute to unravel the pathophysiology of neuropathy. Here we demonstrate the feasibility of X-ray phase contrast holographic nanotomography to enable 3D imaging of nerves at high resolution, while covering a relatively large tissue volume. We show
The task of assessing the extent of a gas release during pipeline emergency situations is challenging. Traditional methodologies for risk analysis require significant computer capabilities and time; factors that have traditionally made emergency response teams unable to use gas dispersion modelling during real incidents.
The Norwegian Offshore Regulator requires top executives to confirm the safety of their installations with particular focus on established barriers towards large scale accidents. StatoilHydro has implemented a structured approach for assessing the technical safety condition of its key barriers. Performance Standards (PS's) are defined for each barrier and each PS defines a set of Performance Requi
Statoil has implemented a structured approach for assessing the condition of the safety barriers on their processing facilities as a key measure to control and reduce major accident risk. The TTS (Teknisk Tilstand Sikkerhet, Norwegian for technical condition safety) methodology is developed with a strong focus on assessing the actual conditions of the technical safety barriers in place to manage m
Chills and vomiting have traditionally been associated with severe bacterial infections and bacteremia. However, few modern studies have in a prospective way evaluated the association of these signs with bacteremia, which is the aim of this prospective, multicenter study. Patients presenting to the emergency department with at least one affected vital sign (increased respiratory rate, increased he
Cell replacement is a long-standing and realistic goal for the treatment of Parkinsonʼs disease (PD). Cells for transplantation can be obtained from fetal brain tissue or from stem cells. However, after transplantation, dopamine (DA) neurons are seen to be a minor component of grafts, and it has remained difficult to determine the identity of other cell types. Here, we report analysis by single-ce
I denna rapport redovisas delresultat från ett treårigt forskningsprojekt somfinansieras av AFA-försäkringar. Projektet heter ”Skolledares arbetsmiljö: Ettprojekt om organisatoriska förutsättningar, stressrelaterad psykisk ohälsa,personalrörlighet och förbättringspotential”. Projektet är ett tvärvetenskapligtsamarbete mellan Avdelningen för arbets- och miljömedicin (AMM) ochInstitutionen för psyko
Patients with chronic pancreatitis have an impaired quality of life and are at risk for several long-term complications. It is important to diagnose and treat these patients to minimize the effects of the disease. Clinical manifestations of chronic pancreatitis include a wide range of symptoms and patients are managed differenth between medical centers. In recent years, there have been improvement
OBJECTIVES: Chronic lung allograft dysfunction including Bronchiolitis obliterans syndrome (BOS) is common after lung transplantation. Histologically, BOS is recognized as fibrotic lesions with accumulated extracellular matrix (ECM) in small airways. Lung fibroblasts are major producers of ECM and vascular endothelial growth factor (VEGF). In this study we hypothesize that VEGF is involved in BOS
Organisms in the wild are faced with multiple threats and a common response is a change in behaviour. To disentangle responses to several threats, we exposed two differently sized species of the freshwater invertebrate Daphnia to solar ultraviolet radiation (UVR) and predation from either moving pelagic or benthic ambush predators. Using an advanced nanotechnology-based method, we tracked the thre

Introducing biobased polymers from renewable sources for use as high-performance thermoplastics with high demands on mechanical rigidity, transparency, thermal stability, as well as good processability, is a significant challenge. In the present work we have designed and prepared a rigid biobased bis-spirocylic diol by di-cycloketalization of a bicyclic diketone (cis-bicyclo[3.3.0]octane-3,7-dione
Large-scale science research facilities, such as those for investigation into the smallest components of physical matter, often consist of buildings with quite extraordinary features as regards shape and scale. These architectures are semiotically interesting in several ways: they have extraordinary outer forms that reflect the their inner activities; they require forms of mediation and planning t
