  1. 1. The Archival Life of Home Movies : Regional Reflections and Negotiated Visions of a Shared Past

    Författare :Ashley Smith; Malin Wahlberg; Patrick Vonderau; Patricia R. Zimmermann; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Home movies; amateur film; non-theatrical film; moving images; archiving; film archives; American South; Mississippi; Jim Crow; race; whiteness; witnessing; ordinary; filmvetenskap; Cinema Studies;

    Sammanfattning : This study investigates the ways in which private home movies are transformed into curated archival objects. Through the concept of the archival home movie, it explores the impact of preservation and content description on access, use, and, thus, regional historiography. LÄS MER

  3. 2. Fungal communities of West African ectomycorrhizal woodlands

    Författare :Brendan R. Furneaux; Martin Ryberg; Matthew Smith; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ectomycorrhizal fungi; West Africa; metabarcoding; Sudanian woodlands; community ecology; ethnomycology; edible mushrooms; fungi; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

    Sammanfattning : Ectomycorrhizal symbiosis is a widespread mutualist relationship between fungi and plants, often trees. It is most well-known in temperate and boreal forests, but also occurs in a variety of tropical ecosystems, including Sudanian savanna woodlands and gallery forests in West Africa. LÄS MER

  4. 3. Dual control concepts for linear dynamical systems

    Författare :Mina Ferizbegovic; Håkan Hjalmarsson; Thomas B. Schön; Cristian R. Rojas; Roy Smith; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : We study simultaneous learning and control of linear dynamical systems. In such a setting, control policies are derived with respect to two objectives: i) to control the system as well as possible, given the current knowledge of system dynamics (exploitation), and ii) to gather as much information as possible about the unknown system that can improve control (exploration).

  5. 4. Topics in Computational Algebraic Geometry and Deformation Quantization

    Författare :Christine Jost; Sandra Di Rocco; Boris Shapiro; Gregory G. Smith; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Segre classes; Chern-Schwartz-MacPherson classes; topological Euler characteristic; computational algebraic geometry; numerical algebraic geometry; numerical homotopy methods; deformation quantization; polyvector fields; Fedosov quantization; Grothendieck-Teichmüller group; Mathematics; matematik;

    Sammanfattning : This thesis consists of two parts, a first part on computations in algebraic geometry, and a second part on deformation quantization. More specifically, it is a collection of four papers. In the papers I, II and III, we present algorithms and an implementation for the computation of degrees of characteristic classes in algebraic geometry. LÄS MER

  7. 5. Architecture and circuit design of photon counting readout for X-ray imaging sensors

    Författare :Suliman A Abdalla; Bengt Oelmann; Kenway Smith; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Sammanfattning : Hybrid pixel array detectors for X-ray imaging are based on different technologies for sensor and readout electronics. The readout electronics are based on standard CMOS technologies that are experiencing continuously rapid improvements by means of down-scaling the feature sizes, which in turn lead to higher transistor densities, lower power consumption, and faster circuits.
