An integral equation-based numerical method for scattering from multi-dielectric cylinders is presented. Electromagnetic fields are represented via layer potentials in terms of surface densities with physical interpretations. The existence of null-field representations then adds superior flexibility to the modeling. Local representations are used for fast field evaluation at points away from their
Advanced combustion such as the partially premixed combustion (PPC) is characterized by high energy efficiency. However, they are sensitive to the inlet condition and injection of a combustion engine. Therefore, it is essential to use combustion feedback. The accuracy of the feedback variables, derived from the cylinder pressure signal, is crucial for effective combustion feedback control. This pa
The importance of semi-arid ecosystems in the global carbon cycle as sinks for CO 2 emissions has recently been highlighted. Africa is a carbon sink and nearly half its area comprises arid and semi-arid ecosystems. However, there are uncertainties regarding CO 2 fluxes for semi-arid ecosystems in Africa, particularly savannas and dry tropical woodlands. In order to improve on existing remote-se
The aim is to illustrate how web marketing frame commercial baby food as a value-adding part of weaning practice and discuss how various ways of framing relate to contemporary mothering ideals. Drawing on “practice” and “frame analysis,” we illustrate how four baby food producers’ web marketing frame commercial baby food and weaning as “medical,” “fun” or “convenient.” The analysis shows that the
This article reports findings from a study of weaning from a perspective informed by practice theory. The overall aim is to examine how parents integrate convenience baby food into their everyday feeding practices. The focus is the embedding of convenience baby foods in the routines and rhythms of everyday life and the “do-ability” of different practices. The study is based on fieldwork with ninet
Why do not academic teachers more frequently use results from education, psychology, cognitive sciences, and related fields while planning, carrying out, and evaluating teaching? It has been argued that if only they did, education would improve. It has further been argued that results from these fields are not communicated in ways suitable for teachers from other disciplines, and therefore there i
“Home” has become a commercialised place in contemporary Sweden. As both cause and ef- fect of this development, the Swedish market for furniture and interior decoration has grown significantly during the last twenty years. Retailers, television shows and magazines have con- tributed to a steadily progressing market, where consumers shop for the latest in furniture as well as the latest ideas and
The ability to handle sensory conflicts and use the most appropriate sensory information is vital for successful recovery of human postural control after injury. The objective was to determine if virtual reality (VR) could provide a vehicle for sensory training, and determine the temporal and spatial nature of such adaptive changes. Twenty healthy subjects participated in the study (10 females). T
Dinoflagellates are a group of protists whose genome is unique among eukaryotes in terms of base composition, chromosomal structure and gene expression. Even after decades of research, the structure and behavior of their amazing chromosomes—which without nucleosomes exist in a liquid crystalline state—are still poorly understood. We used flow cytometry and fluorescence in situ hybridization (FISH
Climate change is not only changing the Arctic environment and ecosystems: it is also opening up the idea of the region as a last frontier to be explored. Recent representations of the future for the Arctic have become closely associated with various business-friendly opportunities as the land and sea ice is melting: They often represent so-called win-win solutions to climate change, also for Arct
The Arctic is a popular place to do research. Many countries fund scientific research projects in the region, and international scientists are a considerable part of the Arctic population. Knowledge and expertise about the Arctic is no longer restricted to the Arctic states. Less controversial than flag planting at the North Pole and test drilling for oil, scientists and research stations are ofte
Flexible consumption in the household sector concerns individuals’ daily choices and the routines that develop in their households. Targeting household-level energy consumption therefore requires an understanding of energy consumption in relation to individual household members’ activity patterns. Individual time-diaries reveal when, for how long and where energy-related activities occur, permitti
In this chapter, we discuss the need for deeper knowledge about the relation between people’s daily activities and their electricity use and how to increase our knowledge through time use surveys and the visualization of aggregate activity patterns. To understand people’s energy consumption and how to improve energy efficiency or reduce demand during certain peak hours requires an understanding of
Nuclear power plants generate electricity and a large amount of waste heat which is valuable for cogeneration. District heating (DH) is a suitable technology to decarbonize the European heat sector. By contrast with most of nuclear non-electric applications, nuclear district heating (NDH) has already been implemented in Europe, thus providing us with some valuable empirical insights. This paper in
Purpose: This paper studies a Swedish municipality that wants to go beyond its own operations, involving the local industry in saving energy to improve the environment. The paper aims to analyse the experiences and practical implications of using policy networks for implementing energy-efficiency measures in private industrial companies. Design/methodology/approach: The researchers closely followe
This article analyses the factors influencing stakeholder participation in municipal energy and climate planning, together with stakeholder experiences of participation in such processes. The article presents findings from a survey of 60 Swedish municipalities and detailed case studies of energy and climate planning in five Swedish municipalities to explore which stakeholders are involved, how and
