  2. 2. Tools for Control System Design : Stratification of Matrix Pairs and Periodic Riccati Differential Equation Solvers

    Author : Stefan Johansson; Bo Kågström; Erik Elmroth; Paul Van Dooren; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; control system design; stratification; controllability; observability; matrix pair; canonical forms; linear quadratic regulator; periodic systems; periodic Riccati differential equation; Computer science; Datavetenskap; Numerical Analysis; numerisk analys;

    Abstract : Modern control theory is today an interdisciplinary area of research. Just as much as this can be problematic, it also provides a rich research environment where practice and theory meet. This Thesis is conducted in the borderline between computing science (numerical analysis) and applied control theory. READ MORE

  4. 4. Distribution and Differences : Stratification and the System of Reproduction in a Swedish Peasant Community 1620-1820

    Author : Jonas Lindström; Maria Ågren; Jan Lindegren; Carl-Johan Gadd; Uppsala universitet; []
    Keywords : HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; Peasant; stratification; inequality; reproduction; resources; distribution; social mobility; household; family; community; landholding; principles; conditions; social structure; feudalism; early modern period; Björskog; Sweden; agrarian history; social history; History; Historia;

    Abstract : This dissertation examines the character, conditions and change of peasant stratification in early modern Sweden. Wherever and whenever one looks, one finds that resources were unevenly spread among peasant households. In the literature, there are different, and conflicting, views compatible with this finding.

  5. 5. Steam condensation in a water pool and its effect on thermal stratification and mixing

    Author : Ignacio Gallego-Marcos; Pavel Kudinov; Walter Villanueva; Dominique Bestion; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steam injection; EHS EMS; blowdown pipes; spargers; chugging; oscillatory bubble; CFD; condensation pool; stratification; mixing; Teknisk mekanik; Engineering Mechanics;

    Abstract : The Pressure Suppression Pool (PSP) of a Boiling Water Reactor (BWR) is a large heat sink designed to limit the containment pressure by condensing steam released from the primary coolant system. The development of thermal stratification is a safety concern since it leads to higher containment pressures than in completely mixed conditions, and can affect the performance of systems such as the emergency core cooling and containment spray, which the use PSP as a source of water.
