    Sammanfattning : In this thesis we discuss different types of regularity for distributions which appear in the theory of pseudo-differential operators and partial differential equations. Partial differential equations often appear in science and technology. LÄS MER

  4. 3. Sensory Dynamics in Emulsion Products Differing in Fat Content

    Författare :Karin Wendin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microstructure; smell; texture; rheology; flavour; fat content; taste; sensory analysis; time intensity; ordinary differential equation; polynomial; emulsion products;

    Sammanfattning : Flavour, taste and texture are important qualities when purchasing food and the richness and smoothness of fat are desired properties for many individuals. However, fat is the major nutrition concern of many consumers. It is therefore important to be able to produce attractive products containing low amounts of fat. LÄS MER

  5. 4. Spectral properties of elliptic operators in singular settings and applications

    Författare :Medet Nursultanov; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The present thesis is focused on the investigation of the spectral properties of the linear elliptic operators in the presence of singularities. It is divided into three chapters. In the first chapter, we consider geometric singularities. LÄS MER
