  1. 1. Critical potential and oxygen evolution of the chlorate anode

    Författare :Linda Nylén; Göran Lindbergh; Yohannes Kiros; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chlorate; chloride oxidation; oxygen evolution; critical anode potential; chromate; DSA; mass transport; RDE; Chemical engineering; Kemiteknik;

    Sammanfattning : In the chlorate process, natural convection arises thanks to the hydrogen evolving cathode. This increases the mass transport of the different species in the chlorate electrolyte. There is a strong connection between mass transport and the kinetics of the electrode reactions. LÄS MER

  3. 2. Influence of the electrolyte on the electrode reactions in the chlorate process

    Författare :Linda Nylén; Göran Lindbergh; Ann Cornell; Mårten Behm; Geoeff H Kelsall; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chlorate; chloride oxidation; critical anode potential; chromate; DSA; hydrogen evolution; iron; mass transport; oxygen evolution; REM; RDE; steel; Electrochemistry; Elektrokemi;

    Sammanfattning : The chlorate process is very energy intensive and a major part of the production costs are for electrical energy. Since the electricity prices are constantly increasing and may also vary periodically, the chlorate plants may be forced to adjust their production rate to the price at each moment in order to minimise their costs.

  4. 3. From Facets to Flow: The Electrooxidation of Glycerol on Pd-based catalysts

    Författare :Jai White; Ann M. Cornell; Gunnar Henriksson; Carina Lagergren; Elena Baranova; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; glycerol; electrooxidation; palladium; nickel; alkaline; HPLC; RDE; glycerol; elektrooxidation; palladium; nickel; alkalisk; HPLC; RDE; Chemical Engineering; Kemiteknik;

    Sammanfattning : Glycerol, a by-product of biodiesel refineries, has uses in industries such as cosmetics, food, and pharmaceuticals. However, its usage is small compared to the amount of glycerol produced from biodiesel production. LÄS MER

  5. 4. The Use of Case-Based Reasoning in a Human-Robot Dialog System

    Författare :Karolina Eliasson; Erik Sandewall; Jan Alexandersson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dialog manager; machine learning; case-based reasoning; case-based planning; helicopter; natural language; Computer science; Datalogi;

    Sammanfattning : As long as there have been computers, one goal has been to be able to communicate with them using natural language. It has turned out to be very hard to implement a dialog system that performs as well as a human being in an unrestricted domain, hence most dialog systems today work in small, restricted domains where the permitted dialog is fully controlled by the system.

  7. 5. Transformation and Symbolic Calculations in Filtering and Control

    Författare :Ke Wang-Chen; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis deals with several aspects of optimal control and filtering problems. A fundamental problem in the optimal control theory is the design of a regulatorfora linear system which minimizes a quadratic cost function characterizing the control effort and the deviations of the system from the ideal operation.
