The generation of ab initio three-dimensional (3D) models is a bottleneck in the studies of large macromolecular assemblies by single-particle cryo-electron microscopy. We describe here a novel method, in which established methods for two-dimensional image processing are combined with newly developed programs for joint rotational 3D alignment of a large number of class averages (RAD) and calculati

In this paper, we first present a survey of existing color buffer compression algorithms. After that, we introduce a new scheme based on an exactly reversible color transform, simple prediction, and Golomb-Rice encoding. In addition to this, we introduce an error control mechanism, which can be used for approximate (lossy) color buffer compression. In this way, the introduced error is kept under s

Läromedel för piano/gehörsspel i första hand för grundskollärarutbildningens pianoundervisning, men även för GG- och IE-varianterna av musiklärarutbildningen.

Future pressurized Solid Oxide Fuel Cell- (SOFC) Gas Turbine Hybrid Systems (HS) promise high efficiency at both full-and part-load on account of the upper and lower SOFC temperature limit and the compressor surge line [1]. The compressor surge constraint is also evident in transient HS operation, caused by the slow transients of SOFC temperature imposed by large SOFC plenum, and fast turbo-machin

The paper describes measurements performed in three district heating (DH) substations in semidetached houses. In all these houses more than 40 % of the domestic hot water (DHW) tappings turned out to be shorter than 10 s. The fraction of total energy used to heat this water varied between 2.4 % and 10.2 %, indicating a large influence of households' daily habits. For 60-78 % of tappings, the total

En essä om den dystopiska tendensen i svensk polisfiktion.

Att behålla budgetdisciplin och skapa förutsättningar för långsiktigt god ekonomisk hushållning är en ständigt närvarande utmaning för offentliga organisationer. Den företrädesvis nationalekonomiska forskningensom vi redogör föri denna rapport tyder påatt det är möjligt att förbättra den ekonomiska hushållningen genom att förbättra de regler, procedurer

Purpose The purpose of this study is to develop scenarios exploring information sharing in supply chains in 2025. Design/methodology/approach An intuitive-logic scenario planning technique was used to create images of plausible futures for information sharing in supply chains. A salient feature of this qualitative study is its inductive reasoning where empirical data was collected from semi-struct

Popular Abstract in Swedish Kol-kolinteraktioner utgör starka kemiska bindningar. Detta innebär att de är relativt svåra att både bryta och bilda. Föreliggande avhandling sammanfattar mekanistiska studier av två reaktioner, Stillereaktionen och Heckreaktionen, med hjälp av vilka kol-kolbindningar kan bildas. Ett vanligt förekommande sammanfattningsnamn för denna typ av reaktioner är korskopplingsrThe present thesis deals with various types of palladium(II) and platinum(II) complexes and their use in homogeneous catalysis. The focus has been devoted to mechanistic investigations concerning the Stille and Heck reactions and studies under both catalytic and stoichiometric conditions were conducted. As a stoichiometric probe for studying the transmetallation step in the Stille reaction the pl
