A common and huge challenge in risk and disaster management such as urban flood is the lack of effective communication, especially instant communication from the general public when sudden flooding occurs. There is a strong need to facilitate complementary risk management for authorities to communication with public in addition to mainstream channels. In a recent international project, possibility
To avoid over-treatment of prostate cancer patients following screening for elevated prostate-specific antigen (PSA) levels, keeping patients on active surveillance has been suggested as an alternative to radical treatment. This means reoccurring visits for patients with low-grade cancer to monitor progression. The Prostate Cancer Research International Active Surveillance (PRIAS) study was initia
Two different sum rules for transmission of the coherent electromagnetic field by a particulate slab are established. The particles are assumed spherical, dielectric, and randomly located, and the slab is illuminated by a plane wave at normal incidence. These sum rules are obtained assuming that the particles are passive scatterers and satisfy causality conditions. The sum rules are then employed
En version av detta verk finns redan för sopran och orkester men jag har gjort om det för sopran och stråkkvartett. Opus 115b. Flera framföranden i Sverige genomförda och det finns planer på framföranden både i Prag och i Schweiz men plats och datum är inte beslutade än. opus: Op. 115Concept Lisa Larsson, orchestration Rolf Martinssonduration: 25 minutes / 13 movements / 99 score pagesinstrumen
BACKGROUND: Thirty-eight years of pediatric heart transplantation (pHTx) within the Scandiatransplant organization were analyzed to describe volume trends, regional prevalence, underlying etiologies and outcomes following listing and pHTx.METHODS: Children <18 years listed for pHTx from January 1st 1986 to December 31st 2023 were identified in the Scandiatransplant registry. The cohort was split i
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
A Python package to evaluate Wannier, Wannier–Stark, and EZ (both energy and location Z resolved) levels for quantum cascade lasers is presented. We provide the underlying theory in detail with a focus on the orthonormality and periodicity of the generated states.
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
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
A novel isolation and purification method was developed for producing 1,3-propanediol with high purity and high yield from the mixture containing 1,3-propanediol, 1,2-propanediol, glycerol, and glucose. The developed method, which consisted of phase separation and chromatography, was found to be a simple and efficient procedure for the isolation and purification of 1,3-propanediol from the other c
Nano-LEDs, with sizes smaller than 1 μm and close to sub-wavelengths, have received increasing attention because of their potential applications in next-generation self-emissive displays, visible light communication, optogenetics, maskless lithography, on-chip super-resolution microscopy, etc. In contrast to the top-down fabrication of nano-LEDs, where the efficiency drop caused by dry-etching rel
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
This paper presents analysis of a scheme for iterated identification and control design. The approach is based on least squares identification in closed loop and pole placement design. It has previously been shown that the criteria for control and identification are the same provided that the data filters are chosen properly. The iterated scheme may be viewed as a recursion in model parameters. Ea
As supply uncertainties and increased lead times were more prominent than ever during the covid-19 pandemic, many companies experienced disrupted supply chains and realized the weaknesses in their inventory management and supply chain planning. Many organizations, including the case company in this thesis, Beijer Ref, experienced the impact of the bullwhip effect on their operations. The bullwhip
Adsorption is an important separation technique in chemical engineering, capable of achieving a high purity of product. As it is also capable of concentrating even very low concentrations it was investigated as a possible method to concentrate the product of an ammonia plasma reactor in the EU DARE2X project. As the development of adsorption systems is expensive and time consuming, a simulation of
5 maj 2025 13:00 till 15:00 | Föreläsning Hur ska vi möta den ekologiska krisen? Det talas ofta om politiska och teknologiska lösningar, och om en livsstilsförändring. Men behöver vi också ett förändrat sätt att se på världen? I dessa föreläsningar talar historiker och teologer om ett förändrat synsätt utifrån tidigkristna texter och praktiker. 13.00–14.00 Mountain, Desert, Sky: An Early Monastic
