  1. 11. Root system of seabuckthorn (Hippophaë rhamnoides L.) : morphology, metabolism and gene expression

    Författare :Syed Rehmat Ullah Shah; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Nutrient availability is one of the limiting factors for plant growth and development, and the nutrients on Earth are unevenly distributed. To overcome this, plants adapt by modifying their morphology and physiology, especially of the root system. Seabuckthorn is a small tree growing in temperate regions of Europe and Asia. LÄS MER

  3. 12. IMPROVING DIFFERENTIAL EVOLUTION WITH ADAPTIVE AND LOCAL SEARCH METHODS

    Författare :Miguel Leon; Ning Xiong; Peter Funk; Yigen Zenlander; Kristian Sandström; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Differential Evolution; Adaptation; Memetic algorithm; Evolutionary Algorithm; Computer Science; datavetenskap;

    Sammanfattning : Differential Evolution (DE) is a population-based algorithm that belongs to the Evolutionary algorithm family. During recent years, DE has become a popular algorithm in optimization due to its strength solving different types of optimization problems and due to its easy usage and implementation. LÄS MER

  4. 13. Phagocytic-receptor signaling in human neutrophils

    Författare :Ragnhild Löfgren; Matthias P. Wymann; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The neutrophil granulocyte is one of the most mobile cells in the body and through a number of functions represents the first line of defense against invading pathogens. Adhesion and chemotactic receptors on the cell surface work together through modulation of the cytoskeleton, thereby enabling cell movement. LÄS MER

  5. 14. Is building molecular solid-state structures as easy as playing with Lego?

    Författare :Cédric Borel; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MOF; framework; crystal structures; network; coordination chemistry;

    Sammanfattning : Crystal engineering is a science dealing with molecular solid-state compounds. One major development in the last ten years has been the description of structures as if they were forming network. In this simplified approach to the structures where atoms, molecules, and molecular ions are replaced by a construction of edges and nodes forming a net. LÄS MER

  7. 15. Mathematical Optimization in Flexible Job Shop Scheduling: Modelling, Analysis, and Case Studies

    Författare :Karin Thörnblad; Göteborgs universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Flexible job shop scheduling; Mixed integer linear programming MILP ; Time-indexed formulation; Makespan; Tardiness; Fixture availability; Preventive maintenance; Night shift; Unmanned time window; Dynamic scheduling; Priority rules; Dispatching rules; Critical ratio; Night shift;

    Sammanfattning : The major theme of this thesis is the mathematical optimization modelling of the flexible job shop scheduling problem. This problem is present in the so-called multitask cell—a production cell at GKN Aerospace's facility located in Trollhättan, Sweden—which has served as a case study during the work with this thesis.
