In the context of a decarbonized future where stringent carbon dioxide (CO2) emissions constraints are imposed on vehicles, hydrogen emerges as a promising solution to address emissions directly at the point of use. This chapter explores the potential of using hydrogen to power vehicles, particularly in the context of heavy-duty (HD) internal combustion engine (ICE) applications. Hydrogen vehicles
Recent research into migration in Bangladesh has highlighted that people migrate for better livelihoods, not necessarily in response to climatic stresses and shocks. If facilitated appropriately, internal and international migration can help build adaptive capacity to future environmental and climatic hazards. In this framing, migration happens in the context of a growing city-centred economy that
Free energy calculations play a crucial role in simulating chemical processes, enzymatic reactions, and drug design. However, assessing the reliability and convergence of these calculations remains a challenge. This study focuses on single-step free-energy calculations using thermodynamic perturbation. It explores how the sample distributions influence the estimated results and evaluates the relia
We survey the current state of the art in the use of nonparametric methods to test separability. We focus on three tests: Swofford and Whitney's (1994) joint test of the necessary and sufficient conditions for weak separability; Fleissig and Whitney's (2003) sequential test of those conditions; and Jones and Stracca's (2006) test of the necessary and sufficient conditions for additive separability
Förekomst av farliga ämnen i byggnader medför betydande osäkerheter i projektplanering och budgetuppskattning och innebär hälso och säkerhetsrisk för de boende och för arbetstagare som är involverade i renoverings- och rivningsaktiviteter. Det är praxis inom svenska byggprojekt att avsätta ungefär 15% av budgeten för att hantera oväntade risker av farliga ämnen och oförutsedda händelser. De faktis
The MAX IV 3 GeV linac delivers electron beams to two synchrotron rings and to a dedicated undulator system for X-ray beam delivery in the Short Pulse Facility (SPF). In addition, there are plans to use the linac as an injector for a future Soft X-ray Laser (SXL). For both SPF and SXL operations, longitudinal beam characterisation with a high temporal resolution is essential. For this purpose, a t
We consider a system of equations that model the temperature, electric potential and deformation of a thermoviscoelastic body. A typical application is a thermistor; an electrical component that can be used e.g. as a surge protector, temperature sensor or for very precise positioning. We introduce a full discretization based on standard finite elements in space and a semi-implicit Euler-type metho
Clinical research usually involves time-to-event survival analysis, in which the presence of a competing event is prevalent. It is acceptable to use the conventional Cox proportional hazard regression to model cause-specific hazard. However, this cause-specific hazard cannot directly translate to the cumulative incidence function, and the latter is usually clinically relevant. The subdistribution
Mobile Stroke Units (MSUs) are specialized ambulances that can diagnose and treat stroke patients; hence, reducing the time to treatment for stroke patients. Optimal placement of MSUs in a geographic region enables to maximize access to treatment for stroke patients. We contribute a mathematical model to optimally place MSUs in a geographic region. The objective function of the model takes the tra
The South African forestry supply chain is a complex system that involves both the production of trees (site preparation, re-establishment, tending, and maintenance operations) and the production and distribution of wood products from plantation stands to the pulp- and sawmills. This paper reports on a study that investigated the suitability of discrete-event simulation for modelling forestry supp
PurposeIn the age of digital businesses, the rise of innovative digital transformation has made supply chain transparency (SCT) an essential research topic. While digital technologies provide possibilities for enhancing transparency in supply chains, there is limited research on how digital businesses overcome different SCT issues or provide real-time visibility and traceability. This study aims t
In May 2024 with a subsequent update in June 2025, the Swedish Medical Products Agency’s expert group revised guidelines on the management and treatment of respiratory syncytial virus (RSV) infection. This is an abridged version and commentary on the full recommendation including specific recommendations for the RSV-season 2025/2026. Key points are: (i) RSV is a seasonal, highly contagious infecti
In this study an alternative integration scheme for elasto-plasticity based on a Diagonal Implicit Runge-Kutta (DIRK) scheme originally proposed by Ellsiepen (1999) is investigated. In contrast to clasical approaches, the DIRK scheme is applied to the balance of momentum as well as the constitutive evolution equations. The presented numerical algorithm is applied to an elastoplastic bounadry value
Popular Abstract in Swedish Den rykande startpistolen eller Konsten att ta tid på en flygande elektron Flygande elektroner kan berätta mycket om hur världen sitter ihop. Elektroner som lämnar ytan av något material avslöjar både vilka atomer som finns i materialet och hur de kemiska bindingarna ser ut. Allt detta är nödvändigt att förstå när man vill utveckla nya material – till exempel för kretTime-of-flight (TOF) techniques for energy analysis have been common in electron spectroscopy for many decades. TOF-based electron spectrometers benefit from higher transmission and information rate compared to their main competitor: the hemispherical analyser; the drawback being their lower energy resolution. However, the advent of angle-resolved TOF spectrometers for electron energy analysis cha
