This article discusses ineffective knowledge and information communication as an important barrier to improving energy efficiency in small and medium-sized enterprises (SMEs) and considers how to make functional communication an enabler of future SME energy-efficiency programmes. Energy audits – important tools when addressing energy efficiency in companies – are often performed by professionals w
Turbulent breakup in emulsification devices is a dynamic process. Small viscous drops undergo a sequence of oscillations before entering the monotonic deformation phase leading to breakup. The turbulence-interface interactions prior to reaching critical deformation are therefore essential for understanding and modeling breakup. This contribution uses numerical experiments to characterize the criti
We studied ice-nucleating abilities of particulate emissions from a modern heavy-duty diesel engine using three different types of fuel. The polydisperse particle emissions were sampled during engine operation and introduced to a continuous-flow diffusion chamber (CFDC) instrument at a constant relative humidity RHwater=110 %, while the temperature was ramped between −43 and −32 ∘C (T scan). The t
One of the greatest challenges the world is facing is climate change. The need of reduction of energy use and an increased use of renewable energy in buildings constitutes important climate change mitigation measures.The objective of this research is to investigate methodologies and performance indicators for the evaluation of energy and moisture performance of buildings, including co-benefits whi
In indoor spaces, lighting control systems are highly effective to reduce electric lighting use. Daylight harvesting systems (DHS) promise to deliver the greatest energy savings. This article presents a review about DHS based on recent scientific and technical literature. The review shows that the energy saving potential of DHS lies between 20-60% in comparison with non-dimmed installations. Howev
The high energy consumption of electronic data processors, together with physical challenges limiting their further improvement, has triggered intensive interest in alternative computation paradigms. Here we focus on network-based biocomputation (NBC), a massively parallel approach where computational problems are encoded in planar networks implemented with nanoscale channels. These networks are e
Our current historical moment is marked by a widespread sense of (ongoing and anticipated) crises, prompting calls to change existing economic, political, social, and environmental systems. This discourse has directed increased scholarly and policy-orientated attention to the concepts of “transformation” and “resilience.” However, beyond attention, these concepts have increasingly adopted a place
Att ställa om från fossila bränslen inom sjöfartssektorn kommer att bli ännu svårare än att vända en oljetanker. Det övergripande syftet med denna avhandling, som är förankrad i sustainability transitions-litteraturen, är att öka den nuvarande förståelsen för hur multiskalära uppifrån-och-ner- samt nerifrån-och-upp-processer påverkar sociotekniska förändringar som bidrar till minskade koldioxidutsShifting away from fossil fuels in the maritime shipping sector promises to be even more difficult than turning an oil tanker. Anchored in the sustainability transitions literature, the overall aim of this thesis is to advance the current understanding of how multi-scalar top-down and bottom-up processes influence socio-technical change towards decarbonisation of the global maritime shipping secto
Current standard wound care involves dressings that provide moisture and protection; however, dressings providing active healing are still scarce and expensive. We aimed to develop an ecologically sustainable 3D printed bioactive hydrogel-based topical wound dressing targeting healing of hard-to-heal wounds, such as chronic or burn wounds, which are low on exudate. To this end, we developed a form
Urban Living Labs (ULLs) are widely promoted as experimental spaces for urban innovation, particularly in EU policy contexts. Yet their design is often shaped by current institutional logics, EU-funding structures, and sector-specific constraints, especially in transport, a domain marked by technical path dependencies and dominant narratives of efficiency and optimization. These conditions risk na
Renewable energy will play an important role in the transition to a sustainable energy system. With an increased maturity of renewable energy technologies, issues concerning implementation are becoming more important. The decisions and actions of municipalities and other local actors have a significant influence on the implementation of renewable energy. In this thesis challenges to implementation
Different hadronization effects in high energy interactions are investigated. The frame-work is the Lund model for the strong interaction. A model for baryon production in jet fragmentation is presented and extended to baryon remnant fragmentation in deep inelastic scattering and hadron--hadron collisions. Observables designed to probe hadronization effects on pt correlations are show
The proper handling of alarms is crucial to any automated process control. In practice, many alarms are only distractive and do not represent a fault situation. In an ongoing project a computerized tool is applied, that aims to remove such nuisance alarms, a so-called alarm cleanup. This is a general, systematic approach that takes advantage of the control system's built-in functions, and is a fir
Organo-metal halide perovskites are some of the most promising materials for the new generation of low-cost photovoltaic and light-emitting devices. Their solution processability is a beneficial trait, although it leads to a spatial inhomogeneity of perovskite films with a variation of the trap state density at the nanoscale. Comprehending their properties using traditional spectroscopy therefore
The aim of this paper is to study how local governments in Sweden view the role of public transport in society, and to investigate how public transport is used in a strategic capacity. By studying general policy documents, the ambition is to gain a wider understanding of the role of public transport based on the societal context it is situated in. Documents from 15 regions and 27 municipalities ha
The paper reports on the bias stabilization of a 60-GHz resonant-tunneling diode (RTD)-based oscillator operated in pulsed mode. The oscillator contains an on-chip stabilizing capacitor, enabling the minimum dc consumption possible for such an RTD oscillator to be obtained, since all of the dc current is consumed by the active device. This is achieved without imposing restraints on the output powe
