We propose data-driven surrogate models to solve systems of time-dependent differential equations coupled with noise. Using a feedforward neural network, we separately learn the noise and solution, tackling approximations across regimes with bifurcations and rare events. Focusing on irregular data generated by a stochastic noise model on a one-dimensional spatial lattice coupled to a differential
We investigate the persistance of embedded eigenvalues under perturbations of a certain self-adjoint Schrödinger-type differential operator in L2(R; Rn), with an asymptotically periodic potential. The studied perturbations are small and belong to a certain Banach space with a specified decay rate, in particular, a weighted space of continuous matrix valued functions. Our main result is that the se
We propose a novel hybrid approach that integrates Neural Ordinary Differential Equations (NODEs) with Bayesian optimization to address the dynamics and parameter estimation of a modified time-delay-type Susceptible-Infected-Removed (SIR) model incorporating immune memory. This approach leverages a neural network to produce continuous multi-wave infection profiles by learning from both data and th

Hållbarhet har under de senaste åren fått en allt större betydelse, då den globala uppvärmningen utgör en av vår tids största utmaningar. Fastighets- och byggsektorn står totalt för 40% av den totala energikonsumtionen i Europa. EU arbetar aktivt för att minska energiförbrukningen i byggnader genom direktivet om byggnaders energiprestanda (EPBD). Det långsiktiga målet med direktivet är att unionenSustainability has become increasingly important in recent years as global warming continues to be the most serious threat to our environment. The real estate sector accounts for 40 percent of the total energy consumption in Europe. To address this issue, the European Union initiated the Energy Performance of Buildings Directive (EPBD), which aims to reduce energy consumption and achieve a fully d
Situationen rörande undervattenskablar och ledningar är mer aktuella än någonsin. Med bakgrund i den allt snabbare digitaliseringen i världen, har denna typ av infrastruktur blivit allt viktigare givet dess användning för kommunikationstjänster och energitillgångar. Detta har gjort sådan infrastruktur en sårbar måltavla för hybridkrigföring. Under de senaste tre åren har sådana situationer utspelaThe situation regarding submarine cables and pipelines is more relevant than ever. As the world’s digitalisation keeps increasing, submarine infrastructure acquires more and more importance due to its vitality for communication services and energy reliability, thus becoming a vulnerable target for hybrid warfare. Such acts of deliberate sabotage have surged, with seven incidents being reported in
This paper studies how Sylva Plath’s The Bell Jar can be read from a feminist perspective and, in turn, what some possible benefits and potential risks of teaching the novel and feminist literary criticism to upper secondary school students of English in Sweden are. This paper also discusses how the novel can be a means to discuss the fundamental values of upper secondary school, in terms of equal
Drawing on his anthropological field work in Bolivia in the midst of profound social and political change, the author examines the attitudes of various interlocutors toward knowledge, and in particular the important differences between “hegemonic theories of knowledge and indigenous epistemologies, between propositional and non-propositional knowledge, between knowledge of the world and knowledge
Fram till 1 januari 2015 hade länsstyrelsen möjlighet att besluta om ”113-förordnande” enligt 6 kap. 5 § PBL. 113-förordnandet innebar att kommunen kunde ta mark i anspråk utan ersättning om det ansågs skäligt med hänsyn till den nytta som exploatören förväntades få av planens genomförande och till omständigheterna i övrigt. Hur mark för allmän plats ska värderas och ersättas regleras i 4 kap. 3a
Anti-phospholipid (aPL) antibodies are important contributors to development of thrombosis in patients with the autoimmune rheumatic disease systemic lupus erythematosus (SLE). The underlying mechanism of aPL antibody-mediated thrombosis is not fully understood but existing data suggest that platelets and the complement system are key components. Complement activation on platelets is seen in SLE p
The semantic formalism reference attribute grammars (RAGs) allows graphs to be superimposed on abstract syntax trees. This paper investigates how RAGs can be used to model visual languages, with a case study of a control language that also has a textual syntax. The language contains blocks on which a total execution order is defined based on connections and layout information. One strength of RAGs
The study of religion has its historical origin in the confessional education of religious functionaries, which has influenced the structuring of the study. The order of the topics studied has been, as a rule, first, languages relevant for the study of the normative texts, then the interpretation of these texts, followed by the historical development within the religion, its doctrines (systematic
We have developed a new approach for implementing precise intraprocedural control-flow and dataflow analyses at the abstract syntax tree level. Our approach is declarative, making use of reference attribute grammars augmented with circular attributes and collection attributes. This results in concise executable specifications of the analyses, allowing extensions both to the language and with furth
Algorithms for solving systems of polynomial equations are key components for solving geometry problems in computer vision. Fast and stable polynomial solvers are essential for numerous applications e.g. minimal problems or finding for all stationary points of certain algebraic errors. Recently, full symmetry in the polynomial systems has been utilized to simplify and speed up state-of-the-art pol
