  2. 11. Development and Evaluation of a Denuder-Filter System Designed for Sampling Diisocyanate Aerosols

    Author : Yvonne Nordqvist; Ulrika Nilsson; Peter Haglund; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cylindrical denuder; Diisocyanate; TDI; HDI; IPDI; MDI; Chemosorption; Vapour particle distribution; Aerosol sampling; Analytical chemistry; Analytisk kemi;

    Abstract : There are many occupational environments in which isocyanates or PUR-products are used, produced or processed. During these operations there is always a risk of isocyanate exposure, which may lead to severe health problems. Isocyanates principally affect the respiratory system and they are the main cause of occupational asthma. READ MORE

  4. 12. A naïve sampling model of intuitive confidence intervals

    Author : Patrik Hansson; Peter Juslin; Ralph Hertwig; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; overconfidence; subjective probability; sampling model; short-term memory; age-differences.; Psychology; Psykologi;

    Abstract : A particular field in research on judgment and decision making (JDM) is concerned with realism of confidence in one’s knowledge. An interesting finding is the so-called format dependence effect, which implies that assessment of the same probability distribution generates different conclusions about over- or underconfidence depending on the assessment format.

  5. 13. Towards Dense Air Quality Monitoring : Time-Dependent Statistical Gas Distribution Modelling and Sensor Planning

    Author : Sahar Asadi; Achim Lilienthal; Amy Loutfi; Dominque Martinez; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mobile robot olfaction; time-dependent gas distribution modelling; temporal sub-sampling; sensor planning; artificial potential field; gas monitoring;

    Abstract : This thesis addresses the problem of gas distribution modelling for gas monitoring and gas detection. The presented research is particularly focused on the methods that are suitable for uncontrolled environments. READ MORE

  6. 14. An Experimental Study of Liquid Steel Sampling

    Author : Ola Ericsson; Pär Jönsson; Andrey Karasev; Malin Hallberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; liquid steel sampling; slag protection; filling velocity; solidification rate; sample homogeneity; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

    Abstract : Sampling of liquid steel to control the steel making process is very important in the steel industry. However, there are numerous types of disposable samplers and no united standard for sampling. The goal in this study is to investigate the effect of slag protection type and sample geometry on sampling parameters and sample homogeneity. READ MORE

  7. 15. Spatial distribution and conservation planning of seabed biological diversity

    Author : Genoveva Gonzalez-Mirelis; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spatial autocorrelation; ecological classifications; distribution modelling; biotopes; conservation planning; biodiversity surrogates; GIS; spatial ecology; benthos; fjord;

    Abstract : Knowledge of spatial patterns of biota has become a commodity for conservation practitioners and spatial ecologists alike. This type of information enables the identification of representative and unique biological features (at some nominal scale) which itself constitutes the application par excellence of knowledge of biodiversity distribution as it relates to the design of reserve networks and the realization of spatial planning.
