  1. 1. Sampling from large flotation cells An invastigation of spatial distribution

    University dissertation from Luleå : Luleå University of Technology

    Author : Lisa Malm; Luleå tekniska universitet.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flotation; sampling; Mineral Processing; Mineralteknik;

    Abstract : The general trend in flotation technology today is towards larger flotation cells, which enables a higher throughput. However, adverse effects such as segregation and reduced froth transport efficiency have also been observed in larger cells. READ MORE

  2. 2. On Methods for Real Time Sampling and Distributions in Sampling

    University dissertation from Umeå : Matematisk statistik

    Author : Kadri Meister; Umeå universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; Finite population sampling; inferential issues; real time sampling; sequential sampling methods; negative sampling correlations; model-design-based inference; multivariate Bernoulli and multinomial designs; Matematisk statistik; MATHEMATICS Applied mathematics Mathematical statistics; MATEMATIK Tillämpad matematik Matematisk statistik; Mathematical Statistics; matematisk statistik;

    Abstract : This thesis is composed of six papers, all dealing with the issue of sampling from a finite population. We consider two different topics: real time sampling and distributions in sampling. The main focus is on Papers A–C, where a somewhat special sampling situation referred to as real time sampling is studied. READ MORE

  3. 3. Techniques to Calculate Exact Inclusion Probabilities for Conditional Poisson Sampling and Pareto .pi.ps Sampling Designs

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Nibia Aires; Göteborgs universitet.; Gothenburg University.; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sampling theory; conditional Poisson sampling; Pareto pips sampling; order sampling; numerical integration; algorithms;

    Abstract : This thesis consists of five papers and treats two finite population sampling methods, viz. the Conditional Poisson and the Pareto .pi.ps sampling schemes. READ MORE

  4. 4. Aerosols of Isocyanates, Amines and Anhydrides Sampling and Analysis

    University dissertation from Stockholm : Institutionen för analytisk kemi

    Author : Jakob Dahlin; Stockholms universitet.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; isocyanate; amine; aminoisocyanate; organic acid anhydride; denuder; impactor; impinger; air sampling; LC-MS; LC-CLND; di-n-butylamine; DBA; thermal degradation; aerosol; particles; TDI; MDI; HDI; ICA; MIC; IPDI; exposure; occupational health; NATURAL SCIENCES Chemistry Analytical chemistry; NATURVETENSKAP Kemi Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Abstract : This thesis presents methods for air sampling and determination of isocyanates, amines, aminoisocyanates and anhydrides. These organic compounds are generated during thermal degradation of polymers such as polyurethane (PUR) or epoxy.Isocyanates, amines and anhydrides are airway irritants known to cause occupational asthma.

  5. 5. Spatial sampling and prediction

    University dissertation from Umeå : Umeå universitet

    Author : Lina Schelin; Umeå universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Auxiliary variables; Censoring; Inclusion probabilities; Kriging; Local pivotal method; Minimum detection limit; Prediction intervals; Representative sample; Spatial process; Spatial sampling; Semiparametric bootstrap; Mathematical Statistics; matematisk statistik;

    Abstract : This thesis discusses two aspects of spatial statistics: sampling and prediction. In spatial statistics, we observe some phenomena in space. Space is typically of two or three dimensions, but can be of higher dimension. READ MORE
