Dijets are produced in abundance at the Large Hadron Collider as predicted by quantum chromodynamics (QCD). However, several theories beyond the Standard Model of Particle Physics predicts new phenomena, which also result in dijet final states. This thesis presents searches for such new phenomena using different techniques. One approach is to look for jets, that originate from top quarks. We know,

A fuel mass estimation method for short pilot diesel injections is proposed and analyzed in this article. Previous studies showed that the pilot misfire ratio was more strongly correlated with the fuel mass than the on-time. This characteristic is exploited for the fuel mass estimation in a region where it is otherwise challenging to get good estimation accuracy due to the low signal-to-noise rati

Full-field transmission X-ray microscopy (TXM) is a well established technique, available at various synchrotron beamlines around the world as well as by laboratory benchtop devices. One of the major TXM challenges, due to its nanometre-scale resolution, is the overall instrument stability during the acquisition of the series of tomographic projections. The ability to correct for vertical and hori

The sun is the most important energy source for the Earth’s climate system, however, influences of solar variations on climate are not fully understood. Studying past solar activity can improve our understanding of what role the sun plays in Earth’s climate. Cosmogenic radionuclides, such as 10Be in ice cores, are powerful tools to reconstruct past solar activity before the period of direct telesc

Implementation of Bridge weigh-in-motion (B-WIM) measurements and probabilistic approaches in bridge assessment may reveal hidden bridge reserves and changes in reliability levels over their projected service life, providing a key input for optimized bridge management. But, as scientists and engineers and at the same time vendors of our own ideas, we need to be in position to present the results o

Structural Health Monitoring (SHM) has been a subject of major international research in Civil Engineering structures mainly during the last 20 years. While in the beginning, SHM mainly focused on sensor developments, nowadays practical implications regarding the acquisition, collecting and processing of data are being addressed. Indeed, SHM systems have been evolving along the two last decades an

There is a large financial incentive to minimise operations and maintenance (O&M) costs for offshore wind power by optimising the maintenance plan. The integration of condition monitoring (CM) and structural health monitoring (SHM) may help realise this. There is limited work on the integration of both CM and SHM for offshore wind power or the use of imperfectly operating monitoring equipment.

The construction workflow of in-situ concrete frames in multi-storey residential buildings is highly complex and dynamic. Discrete-event simulation (DES) offers capabilities to model and analyse such complexity. Although DES has successfully been used by researchers in a wide range of construction-related applications there are not many examples demonstrating how different simulation outputs (time

Cross-border regions are characterised by many inherent challenges. Such challenges can include differences in languages, cultures, currencies, markets, labour market conditions, political visions and priorities, governance structures – to name but a few. Greater Copenhagen1 is no different in terms of the challenges it faces as a cross-border region.The aim of this study is to investigate the pos

Emergence agitation following anesthesia in children is not uncommon. It is, although generally self-limiting, associated with both patient and parents distress. We conducted a national survey around the management of behavioral and neurocognitive disturbances after surgery/anesthesia including a case scenario about a child at risk for emergence reaction. Premedication with clonidine or midazolam

Safety in density (SID) potentially explains the safety in numbers (SIN) phenomenon by positing that ‘the SIN effect can be reproduced simply through encouraging behaviour that leads to the formation of higher-density cyclist groups’. The study further explores this hypothesis using event-based exposure, queues and groups of road users. Using three different definitions of encounters between road u

Most signals detected by genome-wide association studies map to non-coding sequence and their tissue-specific effects influence transcriptional regulation. However, key tissues and cell-types required for functional inference are absent from large-scale resources. Here we explore the relationship between genetic variants influencing predisposition to type 2 diabetes (T2D) and related glycemic trai

CONTEXT: Once islet autoantibody-positive individuals are identified, predicting which individuals are at highest risk for type 1 diabetes (T1D) is important. A metabolic risk score derived from 2-hour oral glucose tolerance test (OGTT) data, the Diabetes Prevention Trial-Type 1 risk score (DPTRS), can accurately predict T1D. However, 2-hour OGTTs are time-consuming and costly. OBJECTIVE: We aimed

Obesity is the main risk factor behind insulin resistance and type 2 diabetes. Still, the mechanism behind adipocyte dysfunction is not yet resolved. Recently, we reported that rapid actin remodeling correlates with adipose cell size changes after short-term overfeeding. Therefore, we hypothesized that the actin-driven myocardin-related transcription factor (MRTF-A) contributes to impaired mature
