Forecasting foreign exchange rates and financial asset prices in general is a hard task. The best model has often been shown to be a simple random walk, which implies that the price movements are unpredictable. In this thesis models that have been somewhat successful in the past are developed and investigated for different forecasting horizons. The aim is to find models that significantly dominate
Följderna av narkotikamissbruk kostar samhället stora summor pengar varje år. Att beräkna den exakta storleken på dessa summor är omöjligt, eftersom stora delar av den narkotikarelaterade verksamheten är olaglig. De kostnadsberäkningar man kan göra blir ungefärliga uppskattningar. Ändå är det viktigt att försöka, eftersom den kunskap man har om kostnaderna för narkotikamissbrukets konsekvenser utg
Nu påbörjas årets lönerevision vid Luleå tekniska universitet som avser perioden 2024–10–01 –– 2025–09–30. Även i år har vi ett sifferlöst avtal. För medlemmar i Saco tillämpas på LTU lönesättande samtal vilket innebär att du som anställd i samband med lönerevisionen ska ha två samtal med din närmaste chef. Det första samtalet är tänkt att vara ett ömsesidigt utbyte av information avseende din pre

Motivated by the rising importance of today’s environmental issues and more specifically the role of energy conservation policies, the current study investigates the Granger causal relationship between energy consumption and economic growth in eight European countries. Using a large dataset that overall spans from 1800-2009 the study employs the Toda-Yamamoto procedure and cointegration analysis w
Access is the process of establishing rapport with a field containing different phases without an articulated end. Qualitative research often involves studying people in their social setting, documenting action, and meaning making in relation to the field in which it occurs through ethnographic methods such as observations, shadowing, and interviews. Gaining permission to a site or a specific grou
Permutational Grammar, PG, is a grammar inspired by the Free Word Order grammar, FOG, presented in Vladimir Pericliev & Alexander Grigorov 1992. Some languages, notably Latin, are said to have free word order, see e.g. Siewierska 1988. The name Permutational Grammar is derived from the use of permutations in order to generate order variation. The general problem to be solved by FOG and PG is t
The integration of high-precision cellular localization and machine learning (ML) is considered a cornerstone technique in future cellular navigation systems, offering unparalleled accuracy and functionality. This study focuses on localization based on uplink channel measurements in a fifth-generation (5G) new radio (NR) system. An attention-aided ML-based single-snapshot localization pipeline is The integration of high-precision cellular localization and machine learning (ML) is considered a cornerstone technique in future cellular navigation systems, offering unparalleled accuracy and functionality.

Aims: Our aim was to investigate the psychometric properties of the health assessment instrument EQ-5D-5L in OHCA survivors.Methods: We included survivors from the Targeted Hypothermia versus Targeted Normothermia after OHCA (TTM2) trial, who completed EQ-5D-5L at 6 months. Confirmatory factor analysis was used to evaluate the hypothesised unidimensional latent structure of EQ level sum score (EQ Aims: Our aim was to investigate the psychometric properties of the health assessment instrument EQ-5D-5L in OHCA survivors.Methods: We included survivors from the Targeted Hypothermia versus Targeted Normothermia after OHCA (TTM2) trial, who completed EQ-5D-5L at 6 months.

Free space optics is an interesting alternative for telemetry with medical implants, due to the high data bandwidths available at optical frequencies. Especially implanted brain-computer interfaces gives rise to large data sets that needs to be transmitted transcutaneous. In this paper we show that it is possible to establish such a link at near-IR wavelengths using a modulated reflector in the im
We show that the two problems of computing the permanent of an n*n matrix of poly(n)-bit integers and counting the number of Hamiltonian cycles in a directed n-vertex multigraph with exp(poly(n)) edges can be reduced to relatively few smaller instances of themselves. In effect we derive the first deterministic algorithms for these two problems that run in o(2^n) time in the worst case. Classic pol
Superconducting devices, based on the Cooper pairing of electrons, play an important role in existing and emergent technologies, ranging from radiation detectors1,2 to quantum computers3. Their performance is limited by spurious quasiparticle excitations formed from broken Cooper pairs4–12. Efforts to achieve ultra-low quasiparticle densities have reached time-averaged numbers of excitations on th
Background: The high prevalence of unintended pregnancies and sexually transmitted infections among young people in Sweden are the result of a trend towards increased sexual risk-taking behaviour. While a few qualitative studies suggest that some of these young people take sexual risks as an escape from loneliness, the associations between loneliness and sexual risk-taking behavior are still not w
