The ATLAS Collaboration at CERN is preparing for the data taking and analysis at the LHC that will start in 2007. Therefore, a series of Data Challenges was started in 2002 whose goals are the validation of the Computing Model, of the complete software suite, of the data model, and to ensure the correctness of the technical choices to be made for the final offline computing environment. A major fe
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
Today a broad body of literature has emerged within the IS research community investigating the organizational consequences of IS implementations. However in view of these developments, it seems that practitioners are still faced with implementation problems, such as user dissatisfaction, resistance and mismatches between the new technology and existing work practices. It is this tension, within 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
Following the 2008–2009 global financial crisis, ‘green energy economy’ packages have been implemented to stimulate sustainable economic growth in several Organisation for Economic Co-operation and Development (OECD) countries. Clearly focused on the energy sector, these packages typically include energy-efficiency policy measures and aim to encourage the transition towards a low-carbon economy. W
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
Gaussian Mixture Model (GMM)-based vector quantization of Line Spectral Frequencies (LSFs) has gained wide acceptance in speech coding. In predictive coding of LSFs, the GMM approach utilizing Kalman filtering principles to account for quantization noise has been shown to perform better than a baseline GMM Recursive Coder approaches for both clean and packet loss conditions at roughly the same com
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.
Since January 1, 2005 all publicly traded companies within the EU must prepare their consolidated financial statements in accordance with International Financial Reporting Standards (IFRS). The transition to IFRS brought with it major changes in the accounting for financial instruments through the introduction of the highly controversial accounting standard IAS 39 Financial Instruments: Recognitio
