Can machine learning be used to accurately forecast intraday index returns using candlestick data?

This thesis wants to investigate whether machine learning, trained on candlestick data, can be used to forecast intraday returns. Previous research has primarily focused on returns with longer horizons and is therefore leaving a research gap on shorter horizons. This thesis will use a combination of Convolutional Neural Networks (CNN) and Long Short-Term Memory (LSTM) as the deep learning model to

The Long Shadows of Skyfall: Economic Long-Term Effects of the US Bombing of Cambodia

There is an expanding literature on the economic long-term effects of exogenous shocks such as armed conflict and economic crises. While some studies find evidence of poverty traps, the majority support the neoclassical prediction of eventual catch-up growth. This study contributes to the debate by examining Cambodia, which arguably became the most severely bombed country in history and site of on

The pathways and challenges of the green transition in heavy-duty trucks in China

Under the global carbon neutrality agenda, emission reduction in China’s heavy-duty transport sector is becoming urgent, though the transition faces multiple barriers. Despite China’s leading position in new energy heavy-duty trucks, gaps remain at the strategic and policy levels. This thesis, based on the Multi-Level Perspective (MLP) and Policy Challenge theory, uses policy content analysis, hot

”Fan vad vi betedde oss igår - konstigt att vi inte fick stryk” :en fokusgruppstudie om unga mäns attityder till våld, manlighet och offerskap

Violence is a central part of criminality with young men overrepresented in assault relates violence, both as perpetrator and victim. Our aim of this study was to get a picture of what attitudes ordinary young men have toward masculinity and manliness as well of violence and how these attitudes relate to their picture of the young man as a victim. The empirical material was qualitatively collected

Chemically enhanced primary treatment, microsieving, direct membrane filtration and GAC filtration of municipal wastewater : a pilot-scale study

Chemically enhanced primary treatment (CEPT) followed by microsieving and direct membrane filtration (DMF) as ultrafiltration, was evaluated on pilot scale at a municipal wastewater treatment plant. In addition, a granular activated carbon (GAC) filter downstream of DMF was evaluated for the removal of organic micropollutants. Up to 80% of the total organic carbon (TOC) and 96% of the total phosph

Combination of searches for singly produced vectorlike top quarks in pp collisions at √s = 13 TeV with the ATLAS detector

A combination of searches for the single production of vectorlike top quarks ((Formula presented)) is presented. These analyses are based on proton-proton collisions at (Formula presented) recorded in 2015-2018 with the ATLAS detector at the Large Hadron Collider, corresponding to an integrated luminosity of (Formula presented). The (Formula presented) decay modes considered in this combination ar

Nature by numbers: an evaluation of how DEFRA’s Biodiversity Metric 3.0 can or cannot capture rewilding outcomes

The United Kingdom’s response to the pressing biodiversity decline in England includes the Biodiversity Net Gain (BNG) policy and is operationalised through DEFRA’s Biodiversity Metric, which quantifies biodiversity into ‘biodiversity units’. This thesis evaluates how effectively the metric reflects real biodiversity outcomes at the rewilded Knepp Estate in West Sussex. Using 2005 as a baseline an

Expected tracking performance of the ATLAS Inner Tracker at the High-Luminosity LHC

The high-luminosity phase of LHC operations (HL-LHC), will feature a large increase in simultaneous proton-proton interactions per bunch crossing up to 200, compared with a typical leveling target of 64 in Run 3. Such an increase will create a very challenging environment in which to perform charged particle trajectory reconstruction, a task crucial for the success of the ATLAS physics program, an

Search for charged Higgs bosons produced in top-quark decays or in association with top quarks and decaying via ± →±⁢ in 13 TeV ⁢ collisions with the ATLAS detector

Charged Higgs bosons produced either in top-quark decays or in association with a top quark, subsequently decaying via (Formula presented), are searched for in (Formula presented) of proton-proton collision data at (Formula presented) recorded with the ATLAS detector. Depending on whether the top quark is produced together with the (Formula presented) decays hadronically or semileptonically, the s

Reconstruction and identification of pairs of collimated τ-leptons decaying hadronically using s=13 TeV pp collision data with the ATLAS detector

This paper describes an algorithm for reconstructing and identifying a highly collimated hadronically decaying τ-lepton pair with low transverse momentum. When two τ-leptons are highly collimated, their visible decay products might overlap, degrading the reconstruction performance for each of the τ-leptons. A dedicated treatment attempting to tag the τ-lepton pair as a single object is required. T

Search for diphoton resonances in the 66 to 110 GeV mass range using pp collisions at √s = 13 TeV with the ATLAS detector

A search is performed for light, spin-0 bosons decaying into two photons in the 66 to 110 GeV mass range, using 140 fb−1 of proton-proton collisions at s = 13 TeV produced by the Large Hadron Collider and collected by the ATLAS detector. Multivariate analysis techniques are used to define event categories that improve the sensitivity to new resonances beyond the Standard Model. A model-independent

Emergence of pseudoresonance in high-intensity resonant inelastic x-ray scattering

We report resonant inelastic x-ray scattering (RIXS) spectra of neon atoms interacting with intense x-ray pulses generated using an x-ray free-electron laser (XFEL). We find that an unexpected peak emerges near the Ka line of Ne, which does not coincide with any physical resonances of neon ions. We perform theoretical calculations based on a quantum-state-resolved rate-equation approach with x-ray

Critical habitat thresholds for effective pollinator conservation in agricultural landscapes

Biodiversity in human-dominated landscapes is declining, but evidence-based conservation targets to guide international policies for such landscapes are lacking. We present a framework for informing habitat conservation policies based on the enhancement of habitat quantity and quality and define thresholds of habitat quantity at which it becomes effective to also prioritize habitat quality. We app

Multiplicity dependence of Ξ+c and Ξ0c production in pp collisions at √s=13 TeV

The first measurement at midrapidity (|y| < 0.5) of the production yield of the strange-charm baryons and as a function of transverse momentum (pT) in different charged-particle multiplicity classes in proton-proton collisions at TeV with the ALICE experiment at the LHC is reported. The baryon is reconstructed via the decay channel in the range 4 < pT< 12 GeV/c, while the baryon is reconstructed v

Observation of deuteron and antideuteron formation from resonance-decay nucleons

High-energy hadronic collisions generate environments characterized by temperatures above 100 MeV (refs. 1,2), about 100,000 times hotter than the centre of the Sun. At present, it is therefore unclear how light (anti)nuclei with mass number A of a few units, such as the deuteron, 3He or 4He, each bound by only a few MeV, can emerge from these collisions3,4. Here, the ALICE Collaboration reports t
