Popular Abstract in Swedish Denna avhandling berör metoder för hur beräkningsmekaniken kan förbättras med avseende på förbättrad och effektiv användning av verktyg och resurser. Den berör också ideér för hur verktyg i beräkningsmekanik skall kunna tillämpas i områden där dessa ej tidigare använts. Tre huvudområden har studerats: Effektiv och transparent tillgång till finita element applikationer, This work concern ideas and methods on how the context of computational mechanics can be improved for more efficient utilisation and extended into areas previously not familiar with or capable of using such tools. Three main areas were studied: Providing efficient and transparent access to finite element applications, development of methods for the visualisation of complex phenomena and improving

The new challenge for a construction project management is to meet the demands of sustainable construction, defined by ecological, economical, social and cultural variables. During a facilities lifecycle various activities involves a significant number of stakeholders. It could be those stakeholders who directly are involved, e.g. architects, facility managers or users, and those who more or less

Som en del i Svenska Filminstitutets stora skolbioprojekt Boken på duken – en satsning på film som läsfrämjare i skolan – försöker professor i filmvetenskap Erik Hedling här i essäform karaktärisera kvaliteten hos en riktigt lyckad filmatisering. Hur kommer det sig till exempel att Greta Garbo är en mer trovärdig Anna Karenina än Keira Knightley och att TV-serien är mer trogen originalet men att d

The understanding of condensation of multiple bubbles is of importance to improve the continuum models for the large-scale subcooled flow boiling. The CFD modeling for condensation of multiple bubbles has been developed with the Volume of Fluid (VOF) method in this work. An explicit transient simulation is performed to solve the governing equations along with the VOF equation and source terms for

Popular Abstract in Swedish TNF (Tumor Necrosis Factor eller Tumör-Nekrotisk-Faktor) är en molekyl som utsöndras av kroppens makrofager (latin för storätare) när dessa kommer i kontakt med bakterier. Det TNF som bildas aktiverar andra celler, särskilt vita blodkroppar och de celler som täcker blodkärlsväggens yta (endotelceller). Syftet med detta är att aktivera kroppens immunförsvar och döda baktTNF (Tumor Necrosis Factor) is a pro-inflammatory cytokine which binds to two cell surface receptors, TNF-R55 and TNF-R75. The receptors undergo proteolytic cleavage and release a fragment (soluble TNF-receptors or TNF-Binding Protein), TNF-R55-BP and TNF-R75-BP. Soluble TNF-receptors are able to bind and inactivate TNF. The release of soluble TNF-receptors was measured with ELISA. TNF binding cap

The behaviour of different starches and their mixtures was investigated using several analysis techniques, i.e. small-deformation oscillatory measurements (rheological measurements), differential scanning calo-rimetry (DSC), light microscopy, and UV spectrophotometry (turbidi-metry). Potato, waxy maize and barley starches were mixed two and two in different ratios and at different water contents (

A new frequency offset tracking approach for OFDM has been addressed. Two-dimensional pilot-symbol assisted modulation (2D-PSAM) is employed in coherent OFDM for channel estimation and it is based on inserting known symbols spread out through the 2D time-frequency grid. We show that these scattered symbols can also be employed to perform frequency synchronization. Maximum likelihood estimation has

In the Bologna process, the use of explicit learning goals and formative assessment are central elements in improving student learning. Ideally, formative assessment provides feedback to the student about how his present state relates to the learning goals and enables him to reflect on and regulate his learning. However, we found that it was easier said than done – not just to carry out, but in pa
