The environmental impact of the textile industry is immense, and textile waste is accumulating globally at an unprecedented rate. To address this issue, innovative technologies for handling, sorting, and recycling textile waste are crucial. This thesis presents a comprehensive study on the recycling of cellulosic textile waste through both closed-loop and open-loop pathways. Closed-loop recycling…

Light-emitting diodes (LEDs) are widely applied in fields ranging from solid-state lighting and high-resolution displays to optical communication and sensing. Despite their remarkable technological development, conventional thin-film LEDs remain constrained by strain-induced defects from lattice mismatch and restricted light extraction efficiency due to total internal reflection. Exploration of a…

The development and manufacturing process for Integrated Circuits (ICs) has become complex and globally distributed. System integrators use a mix of custom made logic with third-party Intellectual Property (IP) blocks, untrusted software tools, and external actors for manufacturing, post-production test, and validation. The many untrusted actors involved throughout the IC’s lifetime become a secu…

High-altitude lakes and headwater streams of the Andes provide essential benefits to society, yet they remain among the least studied and most vulnerable freshwater ecosystems. These systems supply drinking water, support agriculture and grazing, regulate floods, store carbon, and hold deep cultural and spiritual value for local communities. However, climate change, land use change, water extract…

In computer graphics, there are numerous aspects that must be considered when rendering images of virtual scenes:What physical light-generating phenomena do we care about? How should object and material surfaces be described? And how should these be stored to ensure as fast and efficient image rendering as possible?As a part of this thesis, a method for rendering images of scenes lit by virtual a…

The Darknet is often portrayed as an online realm marked by deviance and criminality – a space where “anything goes” and therefore requires policing. Yet its cryptoforums remain comparatively understudied. Drawing on three years of ethnographic fieldwork, this dissertation provides new insights into the internal dynamics of a largely hidden online community. Combining digital observations with 19…

The transition toward sustainable energy systems has motivated extensive research into scalable routes for solar fuel generation. Silicon-based photoelectrodes are particularly promising due to their favorable optoelectronic properties, abundance, and compatibility with established microfabrication techniques. Nano-microstructuring silicon can enhance photoelectrochemical performance by improving…

Objective To compare longitudinal speech outcomes at ages 5 and 10 years in foreign-born and Swedish-born children with cleft palate with or without cleft lip (CP ± L), and assess impact of cleft type, additional diagnosed conditions, sex, and age at completed primary palatal surgery.DesignLongitudinal, registry-based cohort study.SettingRegional public care university hospitals in Sweden.Partici…

This brief summarizes expert knowledge on what really works to protect pollinators. To guide and assist national governments and other relevant governmental bodies in the endeavor to stop and reverse pollinator decline, this brief is intended for everyone interested in pollinator and nature restoration, from local practitioners to national and international governmental agencies. German version: …

Monte Carlo ray tracing offers the capability of rendering scenes with large numbers of area light sources-lights can be sampled stochastically and shadowing can be accounted for by tracing rays, rather than using shadow maps or other rasterizationbased techniques that do not scale to many lights or work well with area lights. Current GPUs only afford the capability of tracing a few rays per pixe…

The requirement of higher data rates and the emergence of new wireless device demands in future 5G communication put millimeter-wave frequencies in focus. To investigate electromagnetic-filed exposure at such frequencies for 5G cellular phone application, a planar near-field antenna measurement system is established. A tapered open-ended rectangular waveguide was used as the probe antenna, and a …

The Athenian graffiti functions as a testament of creativity and artistry occurring during the hard times of socioeconomic and political crisis in Greece the last seven years. The impact of Greece's crisis is unavoidably presented through urban art in downtown Athens. This extensive street art practice on Athenian walls as a linguistic and imagery line is approached in this work via the semiotic …

The construction of the European Spallation Source, ESS, started in summer 2014. At the site in Lund, the accelerator tunnel will be completed at the time of IPAC16, while prototyping and manufacturing or prepara-tions for manpower contributions are going on in more 23 laboratories distributed over the 12 European countries collaborating on the accelerator project. Major technical milestones have…
