Airborne depth sounding lidar has proven to be a valuable sensor for rapid and accurate sounding of shallow areas. The received lidar pulse echo contains information of the sea floor depth, but also other data can be extracted. We currently perform work on bottom classification and water turbidity estimation based on lidar data. In this paper we present the theoretical background and experimental

Integration of high-quality oxides on III-V materials allows for versatile design of electronic devices, suitable for RF and power applications. We here present an overview of our results of planar and non-planar III-V MOSFETs for RF electronics, highlighting possibilities and challenges.

This study investigates the interaction dynamics of directly injected (DI) hydrogen and methane jets with wall and neighboring jets in a non-reactive environment, focusing on the influence of wave-shaped piston geometry. Experiments were conducted in a high-pressure optical chamber using a custom 2-hole DI injector, with Schlieren imaging employed to capture the temporal evolution of jet structure

In this work, a novel piston design with wave-structures around the periphery of piston bowl, was studied to investigate the effect of waves on fuel and air mixing, and combustion processes in a heavy-duty optical engine. Lower soot emissions were achieved with this piston geometry in previous works. High-speed particle image velocimetry (PIV) was used to capture the flow field inside the combusti

An outpouring of scholarly editions: Media history perspectives on the editing of historical sources in Sweden, 1834–1847This article examines the scholarly editing of historical sources for publication in nineteenth-century Sweden. The analysis focuses on the approximately 500 letters exchanged between Hans Järta, the Director General of the National Archives of Sweden, and Bror Emil Hildebrand,

Public libraries are increasingly acknowledged as important social infrastructures that can stimulate a sense of community, social cohesion and mental wellbeing. This paper investigates how (inter)national, provincial and local policies conceptualise and fund libraries as social infrastructures in three European cities. Drawing on 32 semi-structured interviews with library management and associatiPublic libraries are increasingly acknowledged as important social infrastructures that can stimulate a sense of community, social cohesion and mental wellbeing.

On-chip light broadcasting can reduce spatial footprint and enhance energy efficiency in photonic neuromorphic systems. We demonstrate on-chip light transmission between InP nanowire photodiodes on silicon, addressing the gap towards complete nanoscale photonic integrated circuits.

Economic sanctions, a key foreign policy tool in global diplomacy, present both challenges and opportunities, yet relatively underexamined in scholarly research. Unlike previous sanctions aimed at natural resources, the US-China trade war targets labour-intensive manufacturing, creating unique opportunities for investment relocation to labour-abundant countries. Vietnam’s success in attracting sub

Forced displacement is a growing issue worldwide, driving individuals to flee and leave their livelihoods behind. Many of those forced to flee in previous years are now undergoing repatriation, with the number of returns expected to rise. However, Afghanistan’s unstable conditions, particularly for women, pose economic challenges for returnees. It may restrict their ability to effectively cope wit

This thesis investigates how educational attainment influenced men’s and women’s employment in the industrial sector of the German Democratic Republic (GDR) between 1970 and 1989. While the GDR’s socialist ideology promoted gender equality, reflected in near-universal female labour participation and widespread access to education, persistent gender disparities in employment outcomes raise question

This thesis investigates why tariffs, once the backbone of U.S. federal revenue, cannot replace income taxes as the primary revenue source in the modern American economy. Using a systematic literature review and secondary data analysis approach, the study contrasts the structural conditions of the pre-1913 tariff regime, characterized by a goods-dominated economy and minimal federal spending, with

Advances in Earth observation capabilities mean that there is now a multitude of spatially resolved data sets available that can support the quantification of water and carbon pools and fluxes at the land surface. However, such quantification ideally requires efficient synergistic exploitation of those data, which in turn requires carbon and water land-surface models with the capability to simulta

This paper presents a relational approach to the study of poverty (. Mosse, 2010), and uses this to critically evaluate state strategies for identifying and alleviating poverty in Kerala, India. It traces these from national planning documents through to their point of implementation, drawing on qualitative research in two of Kerala's poorest Districts. Ideas of participatory poverty classificatio

Assertions are one of the most useful automated techniques for checking program’s behaviour and hence have been used for different verification and validation tasks. We provide an overview of the last two decades of research involving “assertions” in software testing. Based on a term-based search, we filtered the inclusion of relevant papers and synthesised them with respect to the problem address

We present an Unmanned Aerial Vehicle (UAV) human-robot interaction simulation environment to evaluate operator situational awareness (SA) during Beyond Visual Line of Sight (BVLOS) operations. We have developed a modular simulator that functions as a testbed for the design of custom scenarios and the study of human-robot interaction. This simulator facilitates data collection and allows for the c

The automotive domain is becoming increasingly complex through the integration of new technologies. As a result, cybersecurity is recognized as a pressing issue. This study focuses on the ISO/SAE 21434:2021 standard for road vehicles cybersecurity engineering, evaluating the effectiveness of the standard’s risk assessment approach. The standard suggests a set of assessment steps, and previous rese
