  2. 1. Deposit formation in the grate-kiln process

    Author : Carrie Jonsson; Lars-Olof Nordin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : Deposit formation in the grate-kiln process is a challenge for the iron ore pellet production industry. The deposits cause disturbances that affect the production capacity of the pelletizing plant. READ MORE

  4. 2. Detecting Inclusions in a Silicone Rubber Phantom Using Standing Lamb Waves and Multiple Frequency Footprints

    Author : Ulf G Jonsson; Britt Andersson; Olof A Lindahl; Jacques Ohayon; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Piezoelectric; Silicone rubber; Impedance; Resonance; Lamb waves; Phantom; Electronics; elektronik;

    Abstract : The thesis deals with one major question: is it possible, using one piezoelectric sensor/vibrator, to detect a hard inclusion in a silicone rubber phantom? The question was approached with an open mind and the task was subdivided into three clearly identifiable parts: characterization of the piezoelectric sensor/vibrator (paper I), creating a model of the visco-elastic properties of a tissue-like material (phantom) in contact with the sensor/vibrator (paper II), and to detect the presence of a hard inclusion in the phantom (paper III). All vibrations of the sensor/vibrator and phantom was modeled using a finite element method (FEM). READ MORE

  5. 3. Predicting Ecosystem Response from Pollution in Baltic Archipelago areas using Mass-balance Modelling

    Author : Olof Magnus Karlsson; Andreas Bryhn; Lars Håkanson; Per Jonsson; Mikael Malmaeus; Kristoffer Naes; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; archipelagos; aquatic ecosystems mass-balance modelling; sediment-water dynamics; phosphorus; dioxins; PCDD Fs; Other earth sciences; Övrig geovetenskap; Earth Science with specialization in Environmental Analysis; Geovetenskap med inriktning mot miljöanalys;

    Abstract : Baltic archipelago areas have high nature values despite being polluted from various antrophogenic activities within the Baltic Sea catchment area and from long-range transport of airborne substances. The discovery of environmental problems in the Baltic Sea in the 1960s led to countermeasures that gradually gave results in reducing the toxic pollution, e. READ MORE

  7. 5. Model-Based Protocol Testing in an Erlang Environment

    Author : Johan Blom; Bengt Jonsson; Sven-Olof Nyström; Bernhard Aichernig; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Testing; Erlang; Model-Based Testing; Symbolic Execution; Communication Protocols; Datavetenskap; Computer Science;

    Abstract : Testing is the dominant technique for quality assurance of software systems. It typically consumes considerable resources in development projects, and is often performed in an ad hoc manner. This thesis is concerned with model-based testing, which is an approach to make testing more systematic and more automated. READ MORE
