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
Although a great variety of strategies to suppress Li dendrite have been proposed for lithium metal batteries (LMBs), a deeper understanding of the factors playing a crucial role during extended electrochemical cycling is often lacking. Herein, the morphological reversibility of the Li-based anode for next-generation batteries under three prevalent strategies, i.e., the use of Li-Al alloys, polyme
This paper addresses the path-tracking problem of time-optimal trajectories under model uncertainties, by proposing a real-time predictive scaling algorithm. The algorithm is formulated as a convex optimization problem, designed to balance the trade-off between improving feasibility and time optimality of a trajectory. The predicted trajectory is scaled based on the presence of path segments that
One of the biggest expenses for airline companies is the fuel for the aircrafts; preceded only by labor costs it is important for an airline to optimize its use of fuel. One option to save money on fuel is by doing something called Fuel Tankering. Essentially, fuel tankering is a way to lower the fuel cost by refueling at departures where the fuel price is lower than at the destination of the airc
The Swedish electricity market was divided into four bidding areas on 2011.11.01. The division gave implications to the trade of electricity in the spot market as well as the financial market. Four bidding areas create smaller markets and coupled with an unbalance of production and consumption in the areas, the liquidity on contracts for area price risk management has decreased drastically. This e
Bakgrund: Svetsning innebär hälsorisker av olika slag. Luftvägarna är speciellt utsatta eftersom svetsarna utsätts för partiklar och gaser. Syftet med denna studie är att genom litteraturstudier värdera personliga riskfaktorers betydelse för utveckling av luftvägssjukdom vid svetsarbete i svartplåt. Detta kan leda till en mera riktad nyanställningsintervju och medicinsk kontroll av svetsare och i
This study aimed to investigate if mental toughness can be applied on other occupations besides elite sport performers. The relationship between mental toughness and sales personnel at an insurance company in Sweden were targeted. Mental toughness was correlated with two of the personality traits from the five-factor model (extraversion, emotional stability). A modified version of the Mental Tough
This thesis is about the overlooked workload nurses’ hands are daily exposed to. This workload is made up of small tasks, seemingly requiring small efforts that together and over time can cause considerable muscle wear. A large number of these tasks consist of opening packages constructed to ensure that the products are sterile. In this study, the effects these packages have on the users were exam
In recent years, more sophisticated DNA technologies for genotyping have enabled considerable progress in various fields such as clinical genetics, archaeogenetics and forensic genetics. DNA samples previously rejected as too challenging to analyze due to low amounts of degraded DNA can now provide useful information. To increase the chances of success with the new methodologies, it is crucial to
The Neumann–Neumann method is a commonly employed domain decomposition method for linear elliptic equations. However, the method exhibits slow convergence when applied to semilinear equations and does not seem to converge at all for certain quasilinear equations. We therefore propose two modified Neumann–Neumann methods that have better convergence properties and require fewer computations. We pro
In recent years, Knowledge Management (KM) has gained significant attention within the Information Systems (IS) community. The economic importance of data and information, often likened to “data as the new oil,” underscores the critical role of data/information/knowledge management. KM is crucial in both educational and organizational contexts. Despite growing interest, research in KM in Higher Ed
Product design requirements are becoming more and more complex, while the number of available materials is increasing. Polymeric materials are still dominant in many applications, replacing other manufacturing materials. Gears are one of the mechanical parts that are increasingly made of plastic. To effectively replace metal materials, the design process and product material must meet all applicat
The diphtheria toxin-like ADP-ribosyltransferases (ARTDs) are an enzyme family that catalyzes the transfer of ADP-ribose units onto substrate proteins by using nicotinamide adenine dinucleotide (NAD(+)) as a cosubstrate. They have a documented role in chromatin remodelling and DNA repair, and inhibitors of ARTD1 and 2 (PARP1 and 2) are currently in clinical trials for the treatment of cancer. The
Poly(ADP-ribose) polymerases (PARPs) activate DNA repair mechanisms upon stress- and cytotoxin-induced DNA damage, and inhibition of PARP activity is a lead in cancer drug therapy. We present a structural and functional analysis of the PARP domain of human PARP-3 in complex with several inhibitors. Of these, KU0058948 is the strongest inhibitor of PARP-3 activity. The presented crystal structures
Cellular-connected unmanned aerial vehicle (UAV) has attracted a surge of research interest in both academia and industry. To support aerial user equipment (UEs) in the existing cellular networks, one promising approach is to assign a portion of the system bandwidth exclusively to the UAV-UEs. This is especially favorable for use cases where a large number of UAV-UEs are exploited, e.g., for packa
