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
Perspectives on research on the formation of nodular graphite in cast iron
Current views on the mechanism of the formation of nodular graphite in cast iron are examined with respect to their explanatory power. The aim of this review is to find, if possible, a rationale for further studies. Arguments are presented in favour of a comprehensive model, encompassing the characteristics of both the nucleation and the growth of the graphite. A plea is made for focusing on the m

Epidemiological evidence on reproductive effects of persistent organochlorines in humans
Organochlorines are widespread pollutants in humans. Concern about adverse reproductive effects of these compounds arises from accidental exposure of humans and experimental studies. Recently, this issue has been addressed by a number of studies of exposed populations and hospital-based case-referent studies. These studies indicate that high concentrations of persistent organochlorines may adverse

Vanadium oxide nanostructures on Rh(111): Promotion effect of CO adsorption and oxidation
The adsorption of CO and the reaction of CO with pre-adsorbed oxygen at room temperature has been studied on the (2 x 1)O-Rh(1 1 1) surface and on vanadium oxide-Rh(1 1 1) "inverse model catalyst" surfaces using scanning tunnelling microscopy (STM) and core-level photoemission with synchrotron radiation. Two types of structurally well-defined model catalyst V3O9-Rh(1 1 1) surfaces have been prepar

Recurrence-free survival in breast cancer improved by adjuvant tamoxifen--especially for progesterone receptor positive tumors with a high proliferation
Although the beneficial effect on breast cancer of adjuvant tamoxifen (TAM) is well established, in the series studied by our group this effect seems to have been restricted to patients with steroid receptor (especially progesterone receptor (PgR)) positive tumors. However, as some patients with PgR-positive tumors manifested recurrence despite adjuvant TAM treatment, the question arose whether so
Moisture redistribution in screeded concrete slabs
The principal objective for this licentiate thesis is to develop a methodology and evaluation model in order to make the future relative humidity in a screeded concrete slab predictable. Residual moisture in screeded concrete slabs may redistribute to the top screed surface under semi-permeable flooring, thus elevating the relative humidity, RH, and possibly exceed the critical humidity level. Pas
Reference Attributed Grammars
An object-oriented extension to canonical attribute grammars is described, permitting attributes to be references to arbitrary nodes in the syntax tree, and attributes to be accessed via the reference attributes. Important practical problems such as name and type analysis for object-oriented languages can be expressed in a concise and modular manner in these grammars, and an optimal evaluation alg
Integration of IGF, FGF, and anti-BMP signals via Smad1 phosphorylation in neural induction.
Billigare, effektivare och mer kompetent genom samarbete
Hur ska den svenska samhällsstrukturen vara utformad? Vem ska egentligen göra vad? Detta är centrala frågor som idag diskuteras flitigt när man både på nationell och lokal nivå konstaterar att det är gott om framtida utmaningar. Delvis råder det nu en situation där 'hela havet stormar' när den befintliga samhällsstrukturen är under utredning genom t ex Ansvarskommittén. Inom avfallsområdet har eme
Xenoestrogenic activity in blood of European and Inuit populations
BACKGROUND: Human exposure to persistent organic pollutants (POPs) is ubiquitous and found in all individuals. Studies have documented endocrine disrupting effects and impact on reproduction. The aim of the present study was to compare the level of xenoestrogenic activity in serum of groups with varying POP exposure, and to evaluate correlations to the POP biomarkers, 2,2',4,4',5,5'-hexachlorobiph
Mobile Positioning in MIMO System Using Particle Filtering
Abstract—This paper represents the results of a simulation study on positioning of a mobile unit in MIMO settings. We used two different approaches for modeling the mobile movement, combined with a simple geometrical model for the MIMO channel. Three different particle filters were implemented for the position estimation. The results show that all three filters are able to achieve estimation accur
Reproductive isolation in temperate reef fishes
pportunity and recognition isolation can lead directly to reproductive isolation, the former via divergence in the location and timing of breeding, and the latter via differential mate preferences. We describe the potential significance of these factors in the maintenance of reproductive isolation in a clade of triplefin fishes that occur sympatrically around coastal New Zealand. Specifically, we

Kriging with Nonparametric Variance Function Estimation
A method for fitting regression models to data that exhibit spatial correlation and heteroskedasticity is proposed. It is well known that ignoring a nonconstant variance does not bias least-squares estimates of regression parameters; thus, data analysts are easily lead to the false belief that moderate heteroskedasticity can generally be ignored. Unfortunately, ignoring nonconstant variance when f
