  1. 1. Immersions and their self intersections

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Tobias Ekholm; Uppsala universitet.; [1998]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Regular homotopy; generic immersion; finite order invariant; Vassiliev invariant; self intersection; diffeotopy; framing; spin structure; pin structure; embedding; Seifert surface; linking; 24; MATEMATIK; MATHEMATICS; MATEMATIK; matematik; Mathematics;

    Abstract : Regular homotopy classes of immersions of the k-dimensional sphere Sk into (k + n)-dimensional Euclidean space Rk+n are known to form finitely generated Abelian groups. It is known how to calculate the regular homotopy class of a generic immersion Sk → R2k in terms of its self intersection. READ MORE

  3. 3. Preoperative MRI and PET in suspected low-grade gliomas Radiological, neuropathological and clinical intersections

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anna Falk Delgado; Uppsala universitet.; [2015]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Low-grade glioma; MRI; PET; FA; MD; Perfusion; Diffusion; Neuropathology; Oligodendroglioma; Astrocytoma; PET; tractography; DTI; DTT; Radiology; Radiologi;

    Abstract : Background: Gliomas are neuroepithelial tumours classified by cell type and grade. In adults, low-grade gliomas are comprised mainly of astrocytomas and oligodendrogliomas grade II. READ MORE

  4. 4. Mind off driving: Effects of cognitive load on driver glance behaviour and response times

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Emma Nilsson; [2018]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cognitive load; visual behaviour; lead vehicle braking; traffic safety; distraction; response times; driver behaviour; intersections;

    Abstract : Introduction: Safe driving requires drivers to look at relevant information in the traffic environment and react in time in case a critical event arises. Concerns exist that cognitively loading tasks might interfere with drivers’ abilities to do this. READ MORE

  5. 5. Intersections on moduli spaces of curves

    University dissertation from Stockholm : Matematiska institutionen

    Author : Sergei Shadrin; Stockholms universitet.; [2004]
    Keywords : Mathematics;

    Abstract : We present a new approach to perform calculations with the certain standard classes in cohomology of the moduli spaces of curves. It is based on an important lemma of Ionel relating the intersection theoriy of the moduli space of curves and that of the space of admissible coverings. READ MORE
