  1. 1. Extensions and Applications of Fast-Lipschitz Optimization

    Författare :Martin Jakobsson; Carlo Fischione; Michael Rabbat; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Fast-Lipschitz optimization is a framework for optimization problems having a special structure in which the optimal solution is given by a set of equations, easily solvable through fixed point iterations. This solution method is simple to implement and particularly well suited for distributed optimization applications, such as those arising in wireless sensor networks. LÄS MER

  3. 3. Geology of Lagoa das Furnas, a crater lake on São Miguel, Azores archipelago

    Författare :Thommy Andersson; Otto Hermelin; Martin Jakobsson; Alasdair Skelton; Erik Sturkell; Richard Gyllencreutz; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Lagoa das Furnas; Azores; crater lake; geophysical mapping; tephrochronology; volcanic dome; maringeologi; Marine Geology;

    Sammanfattning : In this thesis, the results from a geophysical mapping and coring campaign of Lagoa das Furnas are presented. Specific focus is placed on the origin of a subaqueous volcanic cone mapped in the southern part of the lake. LÄS MER

  4. 4. Arctic Ocean benthic foraminifera preservation and Mg/Ca ratios : Implications for bottom water palaeothermometry

    Författare :Natalia Barrientos; Helen Coxall; Martin Jakobsson; Steve Barker; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Arctic Ocean; benthic foraminifera; Mg Ca-temperature; calcite preservation; maringeologi; Marine Geology;

    Sammanfattning : Reconstructions of Arctic Ocean palaeotemperatures are needed to disentangle natural variability from anthropogenic changes and understand the role of ocean heat transport in forcing or providing feedbacks on Arctic climate change. Despite known complications with calcareous microfossil preservation in Arctic Ocean sediments, calcareous benthic foraminifera can be common in interglacial sequences. LÄS MER

  5. 5. On the Late Saalian glaciation : A climate modeling study

    Författare :Florence Colleoni; Martin Jakobsson; Johan Nilsson; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Climate modeling; Eurasian ice sheet; Quaternary; Saalian; surface mass balance; SST; Earth sciences; Geovetenskap; Marine Geoscience; marin geovetenskap;

    Sammanfattning : This thesis focuses on the glaciation of the Late Saalian period (160 -140 ka) over Eurasia. The Quaternary Environment of the Eurasian North (QUEEN) project determined that during this period, the Eurasian ice sheet was substantially larger than during the entire Weichselian cycle and especially that of the Last Glacial Maximum (21 ka, LGM).
