A component-based approach to the design of networked control systems

Component-based techniques revolve around composable, reusable software objects that shield the application level software from the details of the hardware and low-level software implementation and vice versa. Components provide many benefits that have led to their wide adoption it software and middleware developed for embedded systems: They are well-defined entities that can be replaced without a

Laser Spectroscopy in Scattering Media for Biological and Medical Applications

Popular Abstract in Swedish Spektroskopi är den vetenskapsgren som används för att studera samspelet mellan strålning/ljus och materia för tillämpningar i både diagnostiska och terapeutiska syften. Då ljus sänds in i ett prov sätts olika fysikaliska processer igång. I denna avhandling studeras företrädesvis en process som kallas för absorption. Vid absorptionsspektroskopi är våglängden av ljuset, Tunable diode laser absorption spectroscopy can be utilised for gas detection in biological and medical applications. The common approach is to analyse transmitted light according to the Beer-Lambertian law. Normally, the light has a well-defined path length through the gas sample since it can be assumed that it has negligible scattering properties. Samples which, by contrast, have strong scatteri

Cord blood islet autoantibodies are related to stress in the mother during pregnancy.

A 2-month psychological questionnaire concerning pregnancy was answered by 20,920 nondiabetic mothers of singletons. Retrospective analysis showed increased levels of islet autoantibodies (1A) in 290 (1.4%) newborns. High IA levels in the child's cord blood correlated strongly with IA levels in the mother (GADA r = 0.91, P < 0.0001; IA-2A r = 0.75, P = 0.0001). High IA levels were found in newborn

Direct observation of the non-supported metal nanoparticle electron density of states by X-ray photoelectron spectroscopy

Synchrotron-based X-ray photoelectron spectroscopy on copper and silver cluster beams created by a magnetron-based gas-aggregation source has allowed mapping the electron density of states (DOS) of free metallic nanoparticles. The cluster DOS profiles obtained in the experiments strongly resemble the infinite solid DOS shapes, but the extracted cluster work-functions are lower than those for the b

Measurement of rainfall interception by xerophytic shrubs in re-vegetated sand dunes

More than 40 years of re-vegetation using mainly xerophytic shrubs Artemisia ordosica Krasch. and Caragana korshinskii Kom. at Shapotou Desert Experimental Research Station near Lanzhou, China has resulted in established dwarf-shrub and herbaceous cover on sand dunes. Precipitation, as the sole source of water replenishment in the semiarid area, plays a pertinent role in sustaining the desert ecos

Use of phosphorus release batch tests for modelling an EBPR pilot plant

The aim of this study was to evaluate how routinely performed phosphorus release tests could be used when modelling enhanced biological phosphorus removal (EBPR) using activated sludge models such as ASM2d. A pilot plant with an extensive analysis programme was used as basis for the simulations. Without any calibration the prediction of phosphorus removal was poor and the initial release rates fro

Patients' opinion on what constitutes good psychiatric care.

The present study investigates patients' opinion on what constitutes good psychiatric care. It was a qualitative study using an open-ended in-depth interview centring on the patient's experiences of receiving psychiatric care. The subjects were selected to ensure maximum variation and heterogeneity. A model of deliberate sampling for heterogeneity and a modified, stratified sampling method were us

The transition to market-based monetary policy: What can China learn from the European experience?

We discuss the prospects for Chinese money market development and transition to market-based monetary policy operations based on a comparative historical analysis of the present Chinese situation and the development in 11 European countries from 1979 up to the launch of the European Economic and Monetary Union (EMU). Central banks in the latter group of countries typically had an incentive to enco

Deterministic radio broadcasting at low cost

We consider distributed deterministic broadcasting in synchronous radio networks. A node receives a message in a given round if and only if exactly one of its neighbors transmits. The source message has to reach all nodes. We assume that nodes do not know the network topology or even their immediate neighborhood. (Such networks are called ad hoc.) We are concerned with two efficiency measures of b

Active centers, catalytic behavior, symbiosis and redox properties of MoV(Nb,Ta)TeO ammoxidation catalysts

Selective as well as waste forming active centers were defined for MoVNbTeO and MoVTaTeO catalysts in the ammoxidation of propane to acrylonitrile and all catalytic functionalities were assigned to specific elements at the respective active centers. Symbiosis between M1 and M2 phases of these catalysts was observed, with phase cooperation being more extensive in the Nb than Ta containing compositi

Sagans förvandlingar: Eva Wigström som sagosamlare och sagoförfattare

Popular Abstract in Swedish Syftet med denna avhandling är att studera hur sagor kan förändras när de förflyttas från en miljö till en annan. Flytten kan ske på flera plan; från muntligt berättande till skriftlig text, från lantligt proletariat till urban borgerlighet. Utgångspunkt har varit sagoinsamlaren och sagoförfattarens Eva Wigström (1832-1901) som på 1880-talet vandrade Skåne runt för att The purpose of this thesis is to study how fairy tales can change when they are removed from one set of surroundings to another. This movement can occur on several levels; from an orally spoken to a written text, from a rural proletariat to an urban bourgeoisie. The point of departure has been the fairy tale collector and fairy tale writer Eva Wigström (1832-1901) who in the 1880s wandered through

α-l-FucosyItransferases in Human Serum from Donors of Different ABO, Secretor and Lewis Blood-Group Phenotypes

The presence of α-l-fucosyltransferases in human serum of different ABO, secretor and Lewis blood-group phenotypes was investigated with guanosine diphosphate fucose as the sugar donor and low-molecular-weight oligosaccharides, or a macromolecular glycoprotein, as acceptors. In contrast to the α-2-l-fucosyltransferases in human milk, submaxillary glands and stomach mucosa that occur only in ABH se
