In this work, we present the fabrication and analysis of fully-vertical GaN FinFETs with a gate length of 550 nm. The devices with fin widths of around 100 nm reveal normally- OFF behavior and subthreshold swings (SSs) very close to the 60-mV/dec limit. Low hysteresis values indicate low defect densities at the oxide/GaN interface. The devices exhibit low specific ON-resistances at a maximum of ar

The European Spallation Source, now under construction in Lund, Sweden, aims to be the world's most powerful pulsed neutron scattering facility. Driving the neutron source is a 5 MW superconducting proton linear accelerator operating at 4 percent beam duty factor and 14 Hz repetition rate. Nineteen partner institutions from across Europe are working with the Accelerator Division in Lund to design

This thesis was performed in collaboration with Phoniro AB, that develops digitally unlocked products that are mainly used in home care service. The purpose of the project was to develop one of their products through a user-centered design process. To determine which product had the greatest development potential, an evaluation of three products and the associated app was conducted. A custom heuri

This study investigates the impacts of a range of interventions aimed at reducing in emissions in three high-impact sectors in cities: built environment, mobility, and sustainable energy systems. It does so by focusing on four cities around the world that are pioneering circular economy solutions (Bogotá, Glasgow, Genoa and Milan), and uses a GTAP-modelling approach developed by C40, Arup and the

In the era of artificial intelligence of things (AIoT), distributed processing on local devices is growing in popularity. This stems from the need to reduce data transfer to and from central servers, with concerns about privacy and latency encouraging the processing of AI applications on edge devices. However, the computational demands of these applications require an increase in the processing ca

The number of degrees of freedom (NDoF) in a communication channel fundamentally limits the number of independent spatial modes available for transmitting and receiving information. Although the NDoF can be computed numerically for specific configurations using singular value decomposition (SVD) of the channel operator, this approach provides limited physical insight. In this paper, we introduce a

Railways are vital for climate mitigation as a low-carbon mode of transport but must also be resilient to climate change impacts. This study explores dynamic adaptation strategies for coastal railway infrastructure in Sweden, focusing on Trelleborg. Stakeholder workshops informed adaptation pathways using a Dynamic Adaptive Pathways Planning Light (DAPP)-light approach, which enhances stakeholder

The chemical industry must undergo a dual transformation: electrifying energy use and defossilizing carbon feedstocks. This paper, developed by ENGIEs Scientific Council, examines how energy and chemistry can converge to enable this shift. We assess the roles of biomass, recycled plastics, and CO2 as sustainable carbon sources and explore the enabling potential of electrification, low-carbon hydro

RATIONALE: Acute otitis media (AOM) is one of the most common bacterial infections in children worldwide, and the most common reason for prescribing antibiotics. Although serious complications (e.g. mastoiditis or meningitis) are rare, the infection causes acute pain and can lead to hearing impairment. Since AOM often resolves spontaneously, current treatment guidelines recommend an approach of wa

Mesosideriter är sällsynta sten-järnmeteoriter med ett gåtfullt ursprung. Deras ovanliga blandning av skorp- och kärnmaterial har föranlett många bildningsteorier under det senaste århundradet. Några frågor har avsett ursprunget till metallen, huruvida den kom från en annan himlakropp, eller från moderkroppens egen kärna, samt varför det finns så pass lite mantelmaterial. Nedslag har haft en centrMesosiderites are rare stony-iron meteorites with enigmatic origins. Their unusual mix of crustal and core materials have inspired many formation theories over the last century. Some of the outstanding questions have regarded the origin of the metal, whether it came from another celestial body or from within the parent body, and the absence of mantle material. The role of impacts has been central

The Theory of Change (ToC) approach has become popular among the international development community, emerging as a need for organizations to carry out more effective initiatives in the context of an increasingly complex world. The levels at which a ToC process can be aimed are worldwide, organizational, thematic and program or project level. The purpose of this study is to generate a better under

Purpose – The existing literature of open innovation (OI) has focused mainly on large companies and few on SMEs, leaving start-ups with scarce analysis of the use of OI. This paper aims to close that gap and contribute to a better understanding of what drives start-ups to open for innovation, how they use it and comprehend what challenges and benefits OI brings to start-ups. Design/methodology/ap

While industrial robots have traditionally been designed for tasks such as pick-and-place that require a high repeatability, an increasing demand for off-line control and high-precision applications have in recent decades put higher demands on the accuracy of robots. One application in that vain is the detection of X-rays that have been scattered from a sample during X-ray diffraction, which produ

Contactless palmprint recognition is a biometric technology which due to its ease of acquisition, non invasive nature and potentially cheap cost can come to stand competitive to more widely used biometric traits such as finger- or facial recognition. This work uses two different feature extraction methods for palmprint images, the Scale invariant feature transform (SIFT) with an iterative random s
