  1. 1. Non-selfadjoint operator functions

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Axel Torshage; Umeå universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Non-linear spectral problem; numerical range; pseudospectrum; resolvent estimate; equivalence after extension; block operator matrices; operator functions; operator pencil; spectral divisor; joint numerical range; Mathematics; matematik;

    Sammanfattning : Spectral properties of linear operators and operator functions can be used to analyze models in nature. When dispersion and damping are taken into account, the dependence of the spectral parameter is in general non-linear and the operators are not selfadjoint. LÄS MER

  2. 2. Bounds on Hilbert Functions

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Ornella Greco; KTH.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hilbert Functions; Commutative Algebra;

    Sammanfattning : This thesis is constituted of two articles, both related to Hilbert functions and h-vectors. In the first paper, we deal with h-vectorsof reduced zero-dimensional schemes in the projective plane, and, in particular, with the problem of finding the possible h-vectors for the union of two sets of points of given h-vectors.

  3. 3. Early Discourses on Colour and Cinema Origins, Functions, Meanings

    Detta är en avhandling från Stockholm : Acta Universitatis Stockholmiensis

    Författare :Eirik Frisvold Hanssen; Stockholms universitet.; [2006]
    Nyckelord :HUMANIORA; HUMANITIES; colour film; film history; film theory; film technology; film aesthetics; indexicality; intermediality; colour and sound; catalogue; Kinemacolor; Sergei M. Eisenstein; HUMANITIES and RELIGION Aesthetic subjects Film; HUMANIORA och RELIGIONSVETENSKAP Estetiska ämnen Filmvetenskap;

    Sammanfattning : This dissertation is a historical and theoretical study of a number of discourses examining colour and cinema during the period 1909 to 1935 (trade press, film reviews, publications on film technology, manuals, catalogues and theoretical texts from the era). In this study, colour in cinema is considered as producing a number of aesthetic and representational questions which are contextualised historically; problems and qualities specifically associated with colour film are examined in terms of an interrelationship between historical, technical, industrial, and stylistic factors, as well as specific contemporary conceptions of cinema.

  4. 4. Control Lyapunov Functions A Control Strategy for Damping of Power Oscillations in Large Power Systems

    Detta är en avhandling från Stockholm : KTH

    Författare :Mehrdad Ghandhari; KTH.; [2000]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; UPFC; CSC; QBT; Lyapunov function; Control Lyapunov Function; SIME; Sliding mode; TECHNOLOGY Electrical engineering; electronics and photonics Electric power engineering; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Elkraftteknik;

    Sammanfattning : In the present climate of deregulation and privatisation, theutilities are often separated into generation, transmission anddistribution companies so as to help promote economic efficiencyand encourage competition. Also, environmental concerns,right-of-way and cost problems have delayed the construction ofboth generation facilities and new transmission lines while thedemand for electric power has continued to grow, which must bemet by increased loading of available lines.

  5. 5. Limits of functions university students' concept development

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Kristina Juter; Luleå tekniska universitet.; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Matematikundervisning-- högskolan; Mathematics Education; Matematik och lärande;

    Sammanfattning : Avhandlingen består av sex artiklar som föregås av en kappa. Kappan sammanfattar de teorier som använts i artiklarna, empiridelen samt resultat och slutsatser. Fem av artiklarna är publicerade i tidskrifter eller accepterade för publikation i tidskrifter och den återstående är accepterad för publicering i en konferensrapport. LÄS MER
