Surface hydrophobization of cellulose nanomaterials has been used in the development of nanofiller-reinforced polymer composites and formulations based on Pickering emulsions. Despite the well-known effect of hydrophobic domains on self-assembly or association of water-soluble polymer amphiphiles, very few studies have addressed the behavior of hydrophobized cellulose nanomaterials in aqueous medi
To decrease the complexity of motion-planning optimizations, a segmentation and merging strategy for maneuvers is proposed. Maneuvers that are at-the-limit of friction are of special interest since they appear in many critical situations. The segmentation pointsare used to set constraints for several smaller optimizations for parts of the full maneuver, which later are merged and compared withopti
The current enthusiasm for the circular economy (CE) offers a unique opportunity to advance the impact of research on sustainability transitions. Diverse interpretations of CE by scholars, however, produce partly opposing assessments of its potential benefits, which can hinder progress. Here, we synthesize policy-relevant lessons and research directions for a sustainable CE and identify three narr
Background: The aim was to review available biokinetic data, collect own experimental data, and propose an updated compartmental model for 2-[18F]FDG in the frame of the revision of the ICRP report on dose coefficients for radiopharmaceuticals used in diagnostic nuclear medicine. Methods: The compartmental model was developed based on published biokinetic data for 2-[18F]FDG. Additional data on ur
The revised Payment Services Directive (PSD2) is reshaping traditional banking by requiring banks to grant licensed third-party providers (TPPs) access to customer data. This paper explores PSD2’s impact on Fintech market entry, assessing both opportunities and ongoing structural barriers. Through a qualitative investigation, it identifies key barriers such as API standardization gaps, data access
This thesis concerns the evaluation of cost functionals on H2 when designing optimal controllers using finite Youla parameterizations and convex optimization. We propose to compute inner products of stable, strictly proper systems via solving Sylvester equations. The properties of different state space realizations of Laguerre filters, when performing Ritz expansions of the optimal controller are
Parallel-elastic joints can improve the efficiency and strength of robots by assisting the actuators with additional torques. For these benefits to be realized, a spring needs to be carefully designed. However, designing robots is an iterative and tedious process, often relying on intuition and heuristics. We introduce a design optimization framework that allows us to co-optimize a parallel elasti
Highly dynamic robotic tasks require high-speed and reactive robots. These tasks are particularly challenging due to the physical constraints, hardware limitations, and the high uncertainty of dynamics and sensor measures. To face these issues, it's crucial to design robotics agents that generate precise and fast trajectories and react immediately to environmental changes. Air hockey is an example
Compact automated warehouse solutions are a challenge for conventional fire protection systems, such as sprinklers. As an option to sprinkler systems some warehouses employ an Oxygen Reduction System (ORS). When designing an ORS, the most important parameter is the limiting oxygen concentration (LOC). The level of protection attained is directly proportional to the oxygen level applied, which is a
The many challenges of our time call for changes in regional economies, increasingly motivating scholars to dive deep into the mechanisms and possibilities for delivering such change. However, the link between regional change and people’s well-being has often been neglected, assuming that new job opportunities, green industrial path development, or higher-value economic activities are inherently g
This paper proposes an examination of the intersections of materiality, acoustics, and musical performance practice through the prism of instruments of the tuba family.[*] Investigation into the symbiotic relationship between instrumental evolution and performance practice is a crucial facet of any study of timbre and orchestration. The development of musical objects to produce the sound colors de
Människors nyfikenhet och drivkraft att förstå och mäta vår värld har lett till många vetenskapliga framsteg. Vårt ständiga sökande efter kunskap har hjälpt oss att bland annat förhindra sjukdomar, förbättra skördar och förstå de ekosystem vi lever i. Dock varierar förutsättningar och utmaningar för forskning runt om i världen, och i många forskningsmiljöer saknas det tillgång till avancerad labor
Finite Element (FE) model updating is crucial for identifying key parameters in structural design and improving predictive accuracy. Despite extensive research on advanced FE procedures approved for user applications, persistent disparities remain in real-world scenarios, especially for complex materials like wood. Capturing accurate mechanical characteristics with traditional models poses challen
Purpose - One current trend in burner technology is to obtain high efficiency while keeping low levels of NOx emissions. A swirling flow in combustion ensures a fixed position of a compact flame. Therefore, it is necessary to design efficient swirlers. Flow patterns are simulated for the different swirl devices proposed in this work. Two axial-swirlers are studied: one based on curve-vanes consist
