- Reshoring is an emergent theme in research and practice. It is important for researchers to understand the motivating force and prerequisites for these reshoring activities, and to develop a method that supports sustainable reshoring decisions. The purpose of this study is to shed light on the prerequisites for successful reshoring. The preparation for this study consists of a systematic literature review. The findings presented here, however, are revelatory and emerged during a workshop. The findings were further researched at a total of four companies, which were part of data collection in a larger project. This research identified three scenarios, in which preceding manufacturing step, creation of parallel steps, or exploration of overcapacity are central. The paper also presents a stage-gateprocess for reshoring decisions as well as a typology of reshoring alternatives. This research sheds light on prerequisites and contextual factors that enable companies to reshore. The importance of manufacturing capabilities can be seen in literature, but has not yet, to our knowledge, been given sufficient attention. The main practical implication is related to offshoring. Overly-aggressive offshoring can complicate future reshoring. As such, reshoring needs to be considered during offshoring, specifically what manufacturing capabilities that are kept at the domestic location.

- The need for digital building information is increasing, both in the form of 3D city models (as geodata) and of more detailed building information models (BIM). BIM models are mainly used in the architecture, engineering and construction industry, but have recently become interesting also for municipalities. The overall aim of this paper is to study one way of dividing a building, namely the division of a building into building parts in both 3D city models and in BIM models. The study starts by an inventory of how building parts are defined in 3D city model standards (CityGML, the INSPIRE building specification and a Swedish national specification for buildings) and in BIM models (Industry Foundation Classes, IFC). The definition of building parts in these specifications are compared and evaluated. The paper also describes potential applications for the use of building parts, on what grounds a building could be divided into building parts, advantages and disadvantages of having building parts and what consequences it can have on the usage of the building information. One finding is that building parts is defined similar, but not identical in the studied geodata specifications and there are no requirements, only recommendations on how buildings should be divided into building parts. This can complicate the modelling, exchange and reuse of building information, and in a longer perspective, it would be desirable to have recommendations of how to define and use building parts in for example a national context.

Municipal Solid Waste Management from a Systems Perspective
- 2005

Ingår i: Journal of Cleaner Production. - : Elsevier BV. - 0959-6526 .- 1879-1786. ; 13:3, s. 241-252

Tidskriftsartikel (refereegranskat)abstract
- Different waste treatment options for municipal solid waste have been studied in a systems analysis. Different combinations of incineration, materials recycling of separated plastic and cardboard containers, and biological treatment (anaerobic digestion and composting) of biodegradable waste, were studied and compared to landfilling. The evaluation covered use of energy resources, environmental impact and financial and environmental costs. In the study, a calculation model ( ) based on methodology from life cycle assessment (LCA) was used. Case studies were performed in three Swedish municipalities: Uppsala, Stockholm, and Älvdalen. The study shows that reduced landfilling in favour of increased recycling of energy and materials lead to lower environmental impact, lower consumption of energy resources, and lower economic costs. Landfilling of energy-rich waste should be avoided as far as possible, partly because of the negative environmental impacts from landfilling, but mainly because of the low recovery of resources when landfilling. Differences between materials recycling, nutrient recycling and incineration are small but in general recycling of plastic is somewhat better than incineration and biological treatment somewhat worse. When planning waste management, it is important to know that the choice of waste treatment method affects processes outside the waste management system, such as generation of district heating, electricity, vehicle fuel, plastic, cardboard, and fertiliser.

ORWARE : a simulation tool for waste management
- 2002

Ingår i: Resources, Conservation and Recycling. - 0921-3449 .- 1879-0658. ; 36:4, s. 287-307

Tidskriftsartikel (refereegranskat)abstract
- A simulation model, ORWARE (ORganic WAste REsearch) is described. The model is mainly used as a tool for researchers in environmental systems analysis of waste management. It is a computer-based model for calculation of substance flows, environmental impacts, and costs of waste management. The model covers, despite the name, both organic and inorganic fractions in municipal waste. The model consists of a number of separate submodels, which describes a process in a real waste management system. The submodels may be combined to design a complete waste management system. Based on principles from life cycle assessment the model also comprises compensatory processes for conventional production of e.g. electricity, district heating and fertiliser. The compensatory system is included in order to fulfil the functional units, i.e. benefits from the waste management that are kept constant in the evaluation of different scenarios. ORWARE generates data on emissions, which are aggregated into different environmental impact categories, e.g. the greenhouse effect, acidification and eutrophication. Throughout the model all physical flows are described by the same variable vector, consisting of up to 50 substances. The extensive vector facilitates a thorough analysis of the results, but involves some difficulties in acquiring relevant data. Scientists have used ORWARE for 8 years in different case studies for model testing and practical application in the society. The aims have e.g. been to evaluate waste management plans and to optimise energy recovery from waste.

Stabilization of potential superhard RuO2 phases: A theoretical study
- 2002

Tidskriftsartikel (refereegranskat)abstract
- First-principles full-potential linear muffin-tin orbital calculations have been used to study RuO2 in the fluorite (CaF2) and rutile structures. An investigation of the effects of metal and nonmetal alloying, oxygen vacancies, and lattice strain on the phase stabilities and electronic structure has been made. From these theoretical results suggestions on how the cubic phase may be stabilized are made. The pressure induced phase transitions between the rutile, CaCl2, Pa3 and fluorite phases and the bulk moduli of several 4d and 5d transition metal dioxides have also been studied.

Chemical vapour deposition of molybdenum carbides: aspects of phase stability
- 2000

Ingår i: Thin Solid Films. - : Elsevier. - 0040-6090 .- 1879-2731. ; 370:1-2, s. 203-212

Tidskriftsartikel (refereegranskat)abstract
- Thin films of different molybdenum carbides (δ-MoC1−x, γ′-MoC1−x and Mo2C) have been deposited from a gas mixture of MoCl5/H2/C2H4 at 800°C by CVD. The H2 content in the vapour has a strong influence on the phase composition and microstructure. Typically, high H2 contents lead to the formation of nanocrystalline δ-MoC1−x films while coarse-grained γ′-MoC1−x is formed with an H2-free gas mixture. This phase has previously only been synthesized by carburization of Mo in a CO atmosphere and it has therefore been considered as an oxycarbide phase stabilized by the presence of oxygen in the lattice. Our results, however, show that γ′-MoC1−x films containing only trace amounts of oxygen can be deposited by CVD. Stability calculations using a FP-LMTO method confirmed that the γ′-MoC1−x phase is stabilized by oxygen but that the difference in energy between e.g. δ-MoC0.75 and oxygen-free γ′-MoC0.75 is small enough to allow the synthesis of the latter phase in the absence of kinetic constraints. Annealing experiments of metastable δ-MoC1−x and γ′-MoC1−x films showed two different reaction products suggesting that kinetic effects play an important role in the decomposition of these phases.

- The electronic structure and the optical properties of face-centered-cubic C-60 have been investigated by using an all-electron full-potential method. Our ab initio results show that the imaginary dielectric function for high-energy values looks very similar to that of graphite, revealing close electronic structure similarities between the two systems. We have also identified the origin of different peaks in the dielectric function of fullerene by means of the calculated electronic density of states. The computed optical spectrum compares fairly well with the available experimental data for the Vis-UV absorption spectrum of solid C-60.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: The purpose of this study is to analyze the processes of interconnectedness in cross-functional relationships involved in customer value enabling. Design/methodology/approach: In total, 20 in-depth interviews were conducted in three Brazilian companies from different industries. The critical incident technique was used for data collection and analysis. Content analysis was used to characterize the critical incidents within functional area networks. Findings: Six main critical incidents were identified within the studied relationships: process, urgency, lack of trust, capacity and demand imbalance, motivation and challenge. The results show situations in which the collaborative behavior of the actors generates customer value facilitation. Research limitations/implications: The firms studied are small and medium, located in an emerging economy and are resource-constrained. Further research could be performed in organizations in other countries with different sizes and resources. Future studies could also include customers within the analyzed functional networks to evaluate value-in-use behavior. Practical implications: Process, as a critical incident, may be composed of several elements that could affect the processes of value creation. Moreover, the adjustment between production capacity and demand should focus on avoiding propagation of functional problems through the processes. This focus may facilitate spontaneous community behavior and customer knowledge renewal. Originality/value: This paper generates new qualitative bases to characterize the interconnectedness within functional networks within the perspective of relationship marketing. The study of the internal functions and processes revealed several particularities that are not evidenced in the extant literature, which is concentrated in relationships among companies. The quality of the relationship among the members of a functional network may affect the effectiveness of the promises of customer value, more specifically in value enabling.
