Compressed sensing (CS) is a universal low-complexity data compression technique for signals that have a sparse representation in some domain. While CS data compression can be done both in the analog- and digital domain, digital implementations are often used on low-power sensor nodes, where an ultra-low-power (ULP) processor carries out the algorithm on Nyquist-rate sampled data. In such systems

Fetal experience forms the basis for postnatal life. This relationship may be obvious in the newborn infant, although it is sometimes not apparent until later in development. One fetal condition with known implications for later life is intrauterine growth restriction (IUGR), which ranges from being an important factor in perinatal mortality to affecting morbidity in adulthood. The process of grow

The observation in the 1940s, that children to mothers having rubella in the first part of the pregnancy experienced elevated health risks in later life led to a growing interest into whether fetal exposure to other – less severe – diseases could cause health problems as well. Epidemiological studies of the fetal origins of later life health that followed found that, while this indeed was the case

In virtually every organization we find formally appointed managers, but nevertheless we tend to condemn the idea of formal hierarchy and celebrate alternative modes of governance that better respect the discretion of employees. This tension, that seemingly surrounds the vertical dimension of contemporary organizations, forms the backdrop of this study which examines how superiors and subordinates

Idag lever 16 % av alla Europas invånare i kustområden, detta är en fördubbling de senaste 50 året. Samtidigt är kustområdena viktiga för mångfalden inom flora och fauna. Kustområden och våtmarker är viktiga i näringskedjan och för tillgången på t ex dricksvatten, och stränder är viktiga tillgångar för turism och friluftsliv. Europaparlamentet och europeiska unionens råd har tagit fram en rekomm

Mid-infrared polarization spectroscopy (IRPS) was applied to detect HCl in flames. For the first time, sensitive and nonin trusive HCl detection with a manner of high spatial- and temporal-resolution in harsh reactive gas flow has been demonstrated in this work. In an atmospheric pressure premixed CH4/O-2/Ar flat flame, trace level HCl was prepared by seeding small amount chloroform through the Ar

Temperature limitations of Solid Oxide Fuel Cells (SOFC) in transient single operation and steady-state Hybrid System (HS) operation with Gas Turbines (GT) are presented. For transient SOFC simulations, an unsteady-state SOFC model was developed by upgrading a detailed validated steady-state model. As critical SOFC single operation modes, concerning the risk of material cracking due to exceeding S

Using geopotential height data we find a strong correlation between theelectric field strength E of the solar wind and pressure variations inthe stratosphere and troposphere. The large-scale evolution of E seemsto influence the stratospheric pressure in both hemispheres with theexception of the polar regions. For the tropospheric pressure theinfluence is concentrated to an area in the northern Atl

Popular Abstract in Swedish För att celler ska kunna växa och dela sig behöver de många olika ämnen, till exempel vitaminer, mineraler och polyaminer. Polyaminer finns i alla celler och de krävs för att cellerna ska kunna dela eller specialisera sig. Cellerna kan både själva tillverka polyaminer och ta upp dem från omgivningen. I mänskliga celler finns framför allt de tre polyaminerna putrescin, sOur research group has previously shown that treatment with the polyamine biosynthesis inhibitors a-difluoromethylornithine (DFMO) or amidinoindan-1-one 2´-amidinohydrazone (CGP 48664) inhibited S phase progression before any other cell cycle phase was affected. This study was undertaken to further investigate the role of polyamines in the regulation of S phase progression and DNA synthesis. I hav

Skolan är en institution som syftar till att förändra eleverna och deras handlande på en rad olika sätt. Själva meningen med skolans verksamhet är således i realiteten att utöva makt. I denna bok analyseras skolans maktutövning ur fem olika aspekter: — skolans människoförflyttande maktutövning resulterar i att eleverna kommer till skolan vid en viss tidpunkt i sina liv och infinner sig där under
