This report was initiated and conducted as input to the discussions based on the “Vision 2015” document for the Nordic Swan that explicitly states a wish to find ways to make use of ecolabelling in the green public procurement (GPP) setting. In 2014, the Directive (2004/18/EG) on public procurement was revised and replaced by Directive (2014/24/EU). Some of the restrictions in using ecolabelling i
Popular Abstract in English N/AAquatic systems worldwide receive large amounts of organic carbon from terrestrial sources. This ‘allochthonous’ organic carbon (AlloOC) affects critical physical and chemical properties of freshwater ecosystems, with consequences for food web structures and exchange of greenhouse gases with the atmosphere. In the boreal region, loadings of AlloOC are particularly high due to leaching from huge or
Against the deeply ingrained belief that technology is instrumental and neutral, this thesis argues that our relation to technology is inextricably bound up with fantasies. But what is the nature of these fantasies and where do we find them? Are they strictly reserved to the domain of Science Fiction, or can we also find them in more mundane contexts, like the business organization? These are som
This paper compares the language Grafcet with the language Grafchart. Both are graphical languages aimed for sequential control applications. Grafcet is aimed for specification of controller structures, i.e., for local level control applications. Grafchart is based on Grafcet, Petri nets and ideas from objectoriented programming and it can be used for any sequential control application, both appli
Three methods are suggested to identify and quantify flashback and flash forward events based on chemiluminescence recordings of swirling flames. The approaches differ in the procedure to determine the instantaneous flame position. The results revealed that the most robust method is to determine a threshold relative to the instantaneous maximum intensity. Analysis of the complete dataset indicated
How do small states approach their security problems? What types of strategic instruments exist for small states, and when and why are certain strategies chosen rather than others? The security of `weak' states is problematic, demanding trade-offs in the decisions made. Using 19th century Swedish security policy as an example, it is argued here that small states, in their pursuit of security and a
A Sierpinski-like fractal patch antenna with a slant strip in the first iteration is proposed in this article. The parameters of this kind of antenna are analyzed and optimized for dual WLAN application. The added slant strip provides simple probe feeding for compactness and also helps bandwidth enhancement due to multiple modes, which can be evident from current distribution. Measured return loss
This paper describes a new hardware architecture for binary image erosion and dilation. The design is to be used in a self contained real-time surveillance system. Thus, low complexity and low power consumption are main constraints. To achieve this goal the aim has been to reduce memory requirements and the number of memory accesses per pixel. By storing only the number of consecutive ones that ap
In this study, a fully three-dimensional calculation method has been further developed to simulate and analyze various processes in a thick anode duct. The composite duct consists of a porous layer, the flow duct and solid current connector. The analysis takes the electrochemical reactions into account. Momentum and heat transport together with gas species equations have been solved by coupled sou
E-business is becoming more and more common today. The predictions of future growth give clear indications that companies will use e-business more and more. However in the growth of e-business it has been identified that there is a common lack of understanding in customer needs and logistics. In order to reduce some of this non-understanding this thesis seeks answers to the following question: - H
Popular Abstract in Swedish Allt eftersom fler och fler organismers totala uppsättning gener, genomet, sekvenseras ökar fokus på att kartlägga de genprodukter, proteiner, som uttrycks. Att kunna studera de proteiner som uttrycks mer eller mindre vid olika tidpunkter eller cellulära tillstånd utgör en viktig del i sökandet efter kunskap om biologiska och medicinska processer. Studier av den totala The study of the protein complement of a genome is called proteomics. Proteomics can be defined as identification, quantification and characterization of a total set of proteins expressed at different time-points or under different cellular states to provide global information about biological processes. The study of membrane proteins is a challenging area in the development of proteomic research.
The paper presents a review of the scientific literature on computer modeling of socio-technical systems. The aim is to briefly review and discuss modeling approaches that are suitable for the simulation of socio-technical systems, specifically in the context of risk and vulnerability analysis of critical infrastructures. It is found that seven main socio-technical modeling approaches can be disce
