  2. 1. Batch Control and Diagnosis

    Author : Rasmus Olsson; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multivariate Statistical Analysis; State and Parameter Estimation; Dynamic Models; Fault Detection; Exception Handling; Recipe; S88; Batch Control; PCA; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Abstract : Batch processes are becoming more and more important in the chemical process industry, where they are used in the manufacture of specialty materials, which often are highly profitable. Some examples where batch processes are important are the manufacturing of pharmaceuticals, polymers, and semiconductors. READ MORE

  4. 2. Multivariate monitoring, modelling and control for stabilization of bioprocesses

    Author : Christian Cimander; Gunnar Lidén; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The obstacles to overcome low reproducibility and stability of bioprocesses are numerous. Underlying biochemical processes are inherently non-linear, complex and subject to shifting initial conditions. Problems with high variability are also associated to production strains and scale-up of a bioprocess to largescale bioreactors. READ MORE

  5. 3. Analysis of Metabolites in Complex Biological Samples Using LC/MS and Multivariate Data Analysis : Metabolic Fingerprinting and Detection of Biomarkers

    Author : Helena Idborg; Sven Jacobsson; Per-Olof Edlund; Jonas Bergquist; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metabolomics; Metabonomics; Metabolic Fingerprinting; Drug Metabolism; Biomarkers; Human Plasma; Rat Urine; LC MS; ZIC-HILIC; UPLC; UHPLC; ToF; Curve Resolution; Peak Detection; Pattern Recognition; Classification; PCA; PLS; PARAFAC; N-PLS; Data Fusion; Hierarchical Modeling; Batch modeling; Data Concatenation; Breast Cancer; Phospholipidosis; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Abstract : To facilitate early diagnosis of diseases and elucidation of the processes involved in their development and progression, various specific compounds or ‘biomarkers’ are often monitored. The first step is to decide which compounds to analyze. READ MORE

  6. 4. Flotation selectivity, process modelling and simulation for a complex sulphide ore

    Author : Xuemin Yuan; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Abstract : This thesis covers research with different methods on the same fine-grained complex sulphide ore - Petiknäs - from the Skellefte Field in Northern Sweden. Mineralogical research results demonstrate that the degree of liberation of galena, rather than the chemical factors under the current flotation conditions, is the dominant factor affecting Pb grade and recovery, since galena has the same flotation as chalcopyrite if having the same degree of liberation.

  7. 5. An Operational View on Foaming and Slopping Control in Top-blown BOS Vessels

    Author : Mats Brämming; Henrik Saxén; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Abstract : Slag formation plays a decisive role in all steelmaking processes. In top-blowing Basic Oxygen Steelmaking (BOS) i.e., in the LD process, an emulsion consisting of liquid slag, dispersed metal droplets, undissolved particles and solid precipitates will, together with process gases, form an expanding foam.
