  1. 11. 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.

  3. 12. No woman should die while giving life : Does the Health Extension Program improveaccess to maternal health services in Tigray, Ethiopia?

    Författare :Tesfay Gebregzabher Gebrehiwet; Isabel Goicolea; Miguel San Sebastián; Kerstin Edin; Anette Agardh; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Health extension program; maternal health; antenatal care; childbirth; postnatal care; access; utilization; Tigray; Health extension workers; Ethiopia.; folkhälsa; Public health;

    Sammanfattning : Introduction: Ensuring access to universal primary health care is essential to secure a safe and pleasant motherhood and to provide compassionate care for mothers and newborns.However, inequalities in the access to maternal health services still remain a prominent problem in many countries.

  4. 13. Applications of Information Inequalities to Linear Systems : Adaptive Control and Security

    Författare :Ingvar Ziemann; Henrik Sandberg; Alexandre Proutiere; Nikolai Matni; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stochastic Adaptive Control; Machine Learning; Fisher Information; Secure Control; Fundamental Limitations; Reinforcement Learning; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : This thesis considers the application of information inequalities, Cramér-Rao type bounds, based on Fisher information, to linear systems. These tools are used to study the trade-offs between learning and performance in two application areas: adaptive control and control systems security. LÄS MER

  5. 14. Anisotropy and non-linear effects in SMC composites : from material data to FE-simulation of structures

    Författare :Magnus Oldenbo; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Sammanfattning : In the design of composite structures for the automotive industry it is vital to have good tools because development time is very critical. Normally simulation of mechanical properties of sheet moulding compound (SMC) composite structures is stiffness based and limited to isotropic material model. LÄS MER

  7. 15. Convex Optimization for Assignment and Generalized Linear Regression Problems

    Författare :Efthymios Tsakonas; Björn Ottersten; Ami Wiesel; KTH; []
    Nyckelord :;

    Sammanfattning : This thesis considers optimization techniques with applications in assignment and generalized linear regression problems. The first part of the thesis investigates the worst-case robust counterparts of combinatorial optimization problems with least squares (LS) cost functions, where the uncertainty lies on the linear transformation of the design variables.
