Remote Supervision of an Unmanned Surface Vessel - a Comparison of Interfaces

We compared three different Graphical User Interfaces (GUI) that we have designed and implemented to enable human supervision of an unmanned ship. Our findings indicate that a 3D GUI presented either on a screen or in a Virtual Reality (VR) setting provides several objective and subjective benefits compared to a Baseline GUI representing traditional tools.

Low-energy behaviour of two-point functions of quark currents

We discuss vector, axial-vector, scalar and pseudoscalar two-point functions at low and intermediate energies. We first review what is known from chiral perturbation theory, as well as from a heat kernel expansion within the context of an extended Nambu-Jona-Lasinio (ENJL) model. We derive then these two-point functions to all orders in the momenta and to leading order in 1/N c within the framewo

Two-body decays of Bs mesons

We have calculated the decay rates of the Bs meson in a number of exclusive two-body decay channels using the Bauer-Stech-Wirbel model for current matrix elements. The influence of the free parameters of the model on the predictions is studied. The total branching ratio of the Bs into final states which only contain stable particles is found to be about 10-3.

Right ventricular remodeling after conduit replacement in patients with corrected tetralogy of Fallot - Evaluation by cardiac magnetic resonance

Purpose: To evaluate the potential for right ventricular reverse remodelling after pulmonary valve replacement using cardiac magnetic resonance imaging, in adults with corrected tetralogy of Fallot and severe pulmonary insufficiency. Material and methods: Ten patients with previous correction of tetralogy of Fallot with severe pulmonary insufficiency accepted for pulmonary valve replacement were

Floodplain mapping using hydraulic simulation model in GIS

In this research, a methodology was applied to integrate hydraulic simulation model, HEC-RAS and GIS analysis for delineation of flood extents and depths within a selected reach of Zaremroud River in Iran. Floodplain modeling is a recently new and applied method in river engineering discipline and is essential for prediction of flood hazards. It is necessary to simulate complicated hydraulic behav

Hyperparameter-selection for sparse regression : A probablistic approach

The choice of hyperparameter(s) notably affects the support recovery in LASSO-like sparse regression problems, acting as an implicit model order selection. Parameters are typically selected using cross-validation or various ad hoc approaches. These often overestimates the resulting model order, aiming to minimize the prediction error rather than maximizing the support recovery. In this work, we pr

Building and operating a real-time massive MIMO testbed - Lessons learned

Massive multiple-input multiple-output (MIMO) is one of the key candidates for the upcoming 5G wireless generation. It offers a multitude of advantages over traditional techniques, such as reduced latency, reduced interference among user equipments (UEs) and increased spectrum and energy efficiencies. However, to verify the theoretically promised gains in real-life, prototype systems are inevitabl

Multidirectionality in the Mental Lexicon : A Case Study of Intensive L3 Acquisition

Much of the current work on third language acquisition focuses on modeling the impact from the speaker’s previous language(s). The Typological Primacy Model (Rothman, 2015), which covers holistic forward transfer at the initial state, and the L2 Status Factor (Bardel and Falk, 2012), which proposes forward transfer from a chronologically true L2, only predict effects on subsequently acquired langu

A novel adeno-associated virus capsid with enhanced neurotropism corrects a lysosomal transmembrane enzyme deficiency

Recombinant adeno-associated viruses (AAVs) are popular in vivo gene transfer vehicles. However, vector doses needed to achieve therapeutic effect are high and some target tissues in the central nervous system remain difficult to transduce. Gene therapy trials using AAV for the treatment of neurological disorders have seldom led to demonstrated clinical efficacy. Important contributing factors are

War and state capacity in the long nineteenth century

A great deal of literature has analyzed the relationship between warfare and state capacity in late-modern and contemporary times. While there is a consensus regarding the significant impact of mass warfare on fiscal expansion during the twentieth century, the interplay between warfare and fiscal capacity in the nineteenth century remains disputed. This paper sheds light on this issue by making us

Reduction of energy demand by use of air sparging during ultrafiltration of alkali-extracted wheat bran hemicelluloses

The flux during membrane filtration can be enhanced by the use of a two-phase gas–liquid flow. This has been shown to be an energy-efficient alternative to increasing the cross-flow velocity. In this work, air sparging was used to increase the flux during ultrafiltration of alkali-extracted wheat bran hemicelluloses. Batch filtration was performed in a pilot unit with a ceramic ultrafiltration mem

Renewable gas in a Swedish context

In order to increase the use of sustainable energy in Sweden, it is necessary to substitute fossil energy carriers with renewable counterparts. Synthetic natural gas (SNG) produced from renewable resources via biomass gasification and methanation could replace a proportion of the natural gas used in Sweden. In order to facilitate the implementation and expansion of SNG production and use in Sweden

Utformning av utrymningssystem i en tunnelbanestation med utrymningshissar : Försök i Virtual Reality-miljö

This report summarizes evacuation experiments performed in a Virtual Reality environment. The experiments are performed in a subway station equipped with evacuation elevators. This study is the second step in the process of ensuring the function of new evacuation solutions. The purpose of the study is to investigate if the exit choice in the subway station can be affected by technical way-finding

A sol-gel integrated dual-readout microarray platform for quantification and identification of prostate-specific antigen

Here, we report a sol-gel integrated affinity microarray for on-chip matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS), which enables capture and identification of prostate-specific antigen (PSA) in samples. Protein microarray technologies, which involve miniaturizing spots of capture agents (such as antibody and aptamers) on a solid surface, enable multia

Limits to EU Powers : a case study on individual criminal sanctions for the enforcement of EU law

The question posed by this thesis is how limits can be constructed to the exercise of EU powers. While there are limits to the exercise of EU competences in the Treaties and in the Court of Justice’s jurisprudence, it is argued that those limits suffer from conceptual and practical problems. In particular, the Court does not have appropriate criteria to examine whether the limits of the Treaties h

Long-term improvements after mindfulness-based group therapy of depression, anxiety and stress and adjustment disorders : A randomized controlled trial

Background: Although mindfulness-based group therapies (MGTs) for depressive, anxiety or stress and adjustment disorders are promising, there is a substantial lack of knowledge regarding the long-term improvements after such therapies in these common psychiatric disorders. Methods: Two hundred and fifteen patients were randomized in a randomized clinical trial (RCT) (ClinicalTrials.gov ID: NCT0147

Cu5In3-Cu3In2 Revisited

The η-phase field of the Cu–In system is unusually rich and shows wealth of phases that are all related to the B8 (NiAs/Ni2In) type. Previous electron diffraction work has revealed extensive super structure ordering; in this study, we report single crystal diffraction experiments on high-quality samples of two of the phases in the system, ht1-Cu5In3 and ht2-Cu5In3. Both these phases constitute sup
