  1. 1. On minimal triangle-free Ramsey graphs

    Författare :Oliver Krüger; Jörgen Backelin; Klas Markström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : A graph G is called a minimal Ramsey (3, k; n)-graph if it has the least amount of edges, e(3, k; n), possible given that G is triangle-free, has independence number α(G) < k an has n vertices. The numbers e(3, k; n) and the minimalRamsey graphs are directly related to the Ramsey numbers R(3, k). LÄS MER

  3. 2. On linear graph invariants related to Ramsey and edge numbers : or how I learned to stop worrying and love the alien invasion

    Författare :Oliver Krüger; Jörgen Backelin; Alexander Engström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ramsey number; edge number; minimal Ramsey graph; independence number; clique number; Turán s theorem; crochet pattern; H13-pattern; linear graph invariant; triangle-free graph; Mathematics; matematik;

    Sammanfattning : In this thesis we study the Ramsey numbers, R(l,k), the edge numbers, e(l,k;n) and graphs that are related to these. The edge number e(l,k;n) may be defined as the least natural number m for which all graphs on n vertices and less than m edges either contains a complete subgraph of size l or an independent set of size k.

  4. 3. Contrast enhanced transrectal ultrasound of the prostate : An experimental and clinical study

    Författare :Else Krüger Hagen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Transrectal ultrasound; Onkologi; Oncology; Onkologi; radiologi; Radiology;

    Sammanfattning : The purpose of this thesis was to evaluate the diagnostic potential of a new ultrasound contrast agent,SonazoidTM, intended for use in patients with suspicion of prostate cancer.The sonographic appearance of normal prostatic vascularity in dogs was evaluated before and after injection of Sonazoid,using different Doppler flow detection modes.

  5. 4. RP59 : a novel stem cell protein and mapping of its expression

    Författare :Anders Krüger-Almerén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The purpose of this thesis was to study the expression pattern of a novel protein daring developmental processes. Firstly we identified so far unknown mRNA sequences coding for frequently expressed proteins in primitive mesenchymal cells in bone marrow and osteoblasts. LÄS MER

  7. 5. Data-Driven Robot Perception in the Wild

    Författare :Karl Holmquist; Michael Felsberg; Klas Nordberg; Zahra Gharaee; Lena Klasén; Norbert Krüger; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : As technology continues to advance, the interest in the relief of humans from tedious or dangerous tasks through automation increases. Some of the tasks that have received increasing attention are autonomous driving, disaster relief, and forestry inspection. LÄS MER
