Linux-based embedded systems are often deployed for long periods, updated in the field, and expected to remain trustworthy under limited maintenance. Secure boot can protect the startup process by verifying software before execution, but practical secure boot depends on more than boot-time signature checks. Trust anchors, key material, provisioning steps, update mechanisms, and release artifacts m
Super-resolution describes a technique for upscaling images from lower to higher resolution. This has proven successful for various applications, ranging from medical image analysis to building segmentation in remote sensing. However, the application of super-resolution to highly complex and dense surfaces, such as informal settlements, has not been widely examined. This is particularly relevant b
Per- och polyfluorerade alkylsubstanser (PFAS) utgör en allvarlig global risk för dricksvatten på grund av sin persistens och höga mobilitet i vattenmiljöer. Vid Gorsingeholms vattenverk i Strängnäs uppvisade PFAS-koncentrationerna i råvattnet från Mälaren låga koncentrationer, men uppvisade förhöjda nivåer efter artificiell infiltration för grundvattenbildning (MAR). Eftersom infiltrationsmateriaPer- and polyfluoroalkyl substances (PFAS) pose severe global risks to drinking water due to their persistence and high aquatic mobility. At the Gorsingeholm water treatment plant in Strängnäs, Sweden, PFAS concentrations in raw intake water from Lake Mälaren exhibited low concentrations yet spiked to heightened levels following initial artificial infiltration for managed aquifer recharge (MAR). B
The account book fabrication industry, a sub-sector of the printing and stationery sector, has experienced a steady decline due to the rapid rise of computerized accounting. Despite its economic significance and continued relevance in semi-urban and rural markets, this industry remains unexplored in academic literature. This study addresses this research gap by investigating how lean manufacturing
Background: Developers increasingly review multi-file code changes generated by LLM-based agents, yet no validated end-to-end workflow or IDE tooling design exists for this scenario.Aims: We investigate (RQ1) the challenges developers face when reviewing LLM-generated multi-file changes and (RQ2) how developers envision effective workflows for this task.Method: In collaboration with JetBrains, we
Currently, electronic commerce food delivery applications (e-food applications) play a significant role in the daily routines of many people. Many e-food applications have been developed, which makes the consumer indecisive in opting for a mobile application of choice for food delivery. Hence, an assessment must be done to quantify the performance of a chosen application with a given set of criter
Gas diffusion layers (GDLs) are critical fibrous porous components utilized in proton exchange membrane fuel cells and water electrolysis systems. Stochastic reconstruction of GDL microstructures facilitates the shift from empirical trial-and-error to performance-driven material design. However, current reconstruction methods often ignore intricate morphological nuances inherent to commercial GDLs
The optimization of coupling between photovoltaic (PV) systems and proton exchange membrane (PEM) electrolyzers is crucial for achieving efficient and scalable hydrogen production. Advances in both technology and software can enhance this integration. While static sizing and electrical coupling methods support location-specific design, they struggle to accommodate the dynamic nature of solar irrad
The burden of disease from ambient and indoor air pollution is highest in low-income countries, while their resources for monitoring air pollutants are the lowest. PM2.5 is the primary indicator of air pollution. Reference monitors of PM2.5 are expensive, but there is an increased use of low-cost sensors (LCS). Three LCS, the UCB-PATS+ (PATS), Airvisual Pro (IQAV) and Sensirion SPS30 (SPSA) are be
Effective irrigation scheduling is essential for improved water management in irrigated areas, with soil moisture monitoring recognized as one of the most effective methods. However, challenges such as the high cost of sensors and the difficulties in monitoring large areas hinder their practical application, particularly for smallholder farmers. This study aimed to design and test a locally made l
This chapter explore cases of language inaccessibility through examples from before and during the COVID-19 pandemic. The examples illustrate inaccessibility of information during daily press conferences, hin- drances to, as well as possibilities of, digitalisation of education, and language barriers emerging through the widespread use of closed captioning for pre-recorded online lectures. Althoug
In today’s dynamic economic climate, businesses are increasingly compelled to reassess their organisational strategies. This shift is driven by varied profitability across sectors, fluctuating market demands, evolving consumer preferences, and heightened sustainability imperatives. To stay competitive, many industries are embracing advanced technologies including big data, cyber-physical systems (
The once abundant European eel (Anguilla anguilla) is currently classified as a Critically Endangered species by the International Union for Conservation of Nature. Although both the European Union (through the 2007 Eel Regulation) and its member states have implemented various conservation actions, many uncertainties remain regarding the actual and anticipated effectiveness of these measures. Thi
BACKGROUND: Knockdown effect, especially in pyrethroid-based household and public insecticides, is often considered a practical indicator of insecticidal efficacy. However, whether faster knockdown implies lethality remains uncertain because the relationship between the two effects has not been systematically explored. This study examined whether knockdown speed is associated with mortality across
Songbirds rely on an endogenous programme encoding spatio-temporal information necessary for naive individuals to perform their first migration. Timing programmes are generated by endogenous clocks and include responses to external cues, with photoperiod being the most important. Photoperiod can advance or delay the circannual cycle and, while it is well established as a trigger for initiating mig
