  1. 1. Developing Methods for Modelling Procedures in System Analysis and System Dynamics

    Author : Hördur Haraldsson; Institutionen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System Dynamics; System Analysis; group model building; modelling procedures; innovation phases; modelling workflow; Natural science; Naturvetenskap; Technological sciences; Teknik;

    Abstract : System Thinking is the mindset of defining and confining a problem and its symptoms as well as a method for communicating system understanding. System Analysis is taking that problem apart to understand its causalities and structural arrangement. READ MORE

  2. 2. The nervous system of box jellyfish: A surprisingly complex system in a simple animal

    Author : Linda Parkefelt; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; proliferating cell nuclear antigen; arginine vasotocin; RFamide; immunofluorescence; visual system; nervous system; Tripedalia cystophora; Cnidaria; box jellyfish;

    Abstract : The four surprisingly complex visual sensory organs of cubomedusae, the rhopalia, contain each six eyes of four morphologically different types, two of which are camera-type eyes. This means that the evolutionary basal nervous system of cubomedusae must process the visual signals received from a total of 24 rhopalial eyes. READ MORE

  3. 3. Power System Oscillations - Detection, Estimation and Control

    Author : Morten Hemmingsson; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; oscillation; power system; damping; power swing; distance protection; detection; estimation; real-time; reactive co-variation; control; Electrical engineering; load modulation; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Abstract : The topic of this thesis is the electro-mechanical oscillations which to some extent always are present in a power system. The demand of electric power is ever increasing. At the same time, the tolerance of disruptions in the power supply is decreasing. READ MORE

  4. 4. Coordinated control of Multi-Stage Inventory System

    Author : Johan Marklund; Produktionsekonomi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inventory systems; multi-echelon; stochastic; decentralization; centralized control; distribution system; divergent system; echelon-stock; installation-stock.;

    Abstract : This thesis is based on three scientific papers dealing with different models for coordinated control of multi-stage inventory systems. The ability to control multi-echelon inventory systems, is paramount for reducing tied up capital and inventory costs in large distribution systems. READ MORE

  5. 5. Probabilistic System Effects in Timber Structures

    Author : Martin Hansson; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building construction; Anläggningsteknik; Construction technology; first order reliability method; Monte Carlo simulation; system effect; sheathed parallel member system; structural timber; roof truss;

    Abstract : The main purpose of the performed research presented in this thesis is to increase the understanding of the effect of variability of strength properties on the reliability of timber structural systems. Compared to other structural materials such as steel and concrete, structural timber has a considerably higher variability of strength both within and between members. READ MORE
