  1. 11. Performance Analysis of Positive Systems and Optimization Algorithms with Time-delays

    Författare :Hamid Reza Feyzmahdavian; Mikael Johansson; Peter Richtarik; KTH; []
    Nyckelord :Optimization; Delay; Positive system; Asynchronous; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Time-delay dynamical systems are used to model many real-world engineering systems, where the future evolution of a system depends not only on current states but also on the history of states. For this reason, the study of stability and control of time-delay systems is of theoretical and practical importance. LÄS MER

  3. 12. Attosecond information encoded in the photoemission angle

    Författare :Johanna Sörngård; Eva Lindroth; Jan-Petter Hansen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; attosecond; photoemission; delay; circular polarization; angular dependence; asymmetry parameters; attosekund; fotoemission; fördröjning; cirkulärpolarisation; vinkelberoende; asymmetriparametrar; Theoretical Physics; teoretisk fysik;

    Sammanfattning : Electrons that break free during photoionization acquire a phase shift induced by the many-body potential of the parent ion. This phase shift can be interpreted as a delay in the photoionization process. LÄS MER

  4. 13. Patient and health care delays in malignant melanoma

    Författare :Senada Hajdarevic; Marcus Schmitt-Egenolf; Carol Tishelman; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Care seeking; delay; diagnosis; decision making; gender; malignant melanoma; nursing; organization; pathways; severity; Allvarlighetsgrad; att söka vård; beslutsfattande; diagnos; fördröjning; genus; malignt melanom; omvårdnad; organisation; remissvägar; omvårdnadsforskning med medicinsk inriktning; Caring Sciences;

    Sammanfattning : Background: Unlike other cancers, malignant melanoma (MM) is generally visible and can be easily and effectively cured if treated in time. Optimal cure of MM requires early detection, diagnosis, and treatment, which improves prognosis. LÄS MER

  5. 14. Observability and identifiability of nonlinear systems with applications in biology

    Författare :Milena Anguelova; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Observability; identifiability; nonlinear systems; time delay; delay systems; state elimination; metabolism; conservation laws; signalling pathways.; signalling pathways.;

    Sammanfattning : This thesis concerns the properties of observability and identifiability of nonlinear systems. It consists of two parts, the first dealing with systems of ordinary differential equations and the second with delay-differential equations with discrete time delays. LÄS MER

  7. 15. Modelling of Traffic Performance for Swedish Roads and Motorways

    Författare :Per Strömgren; Harilaos Koutsopoulos; Nagui Rouphail; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rural highway; Intersection; Capacity; Critical gap; Flare; Micro simulation; Motorway; Ramp; Weaving; Merging; Queue; Delay; Over-saturated; Time-space; Roadwork zone; variable speed limit; harmonization; Transportvetenskap; Transport Science;

    Sammanfattning : This thesis consists of five scientific articles oriented towards capacity. Managing capacity constraints with associated delays is a big issue at new design as well as at trimming existing traffic facilities. LÄS MER
