  1. 1. 5-HT receptor-mediated modulation of glutamate transmission in the hippocampus and prefrontal cortex and its relation to cognition and depression

    Författare :Tiberiu Loredan Stan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Depression is a multifaceted disease which is marked by cognitive and emotional memory impairments. It is characterised by an imbalacement of serotonergic and glutamatergic system in brain areas such as hippocampus and prefontal cortex. LÄS MER

  3. 2. Pair production of Higgs bosons in the final state with bottom quarks and τ leptons in the ATLAS experiment : Search results using LHC Run 2 data and prospect studies at the HL-LHC

    Författare :Petar Bokan; Arnaud Ferrari; Stan Lai; Richard Brenner; Markus Klute; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Higgs boson pair production; ATLAS; LHC; HL-LHC; particle physics; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Sammanfattning : After the discovery of the Higgs boson, the ultimate test of the electroweak symmetry breaking and the Standard Model (SM) of particle physics is to establish evidence of Higgs boson self-coupling, which can be achieved by searching for pair production of Higgs bosons. In addition, many theories beyond the SM predict heavy resonances that could decay into pairs of Higgs bosons. LÄS MER

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; urbanization; planning support system; spatial dynamic model; urban land use change; spatial analysis; human-land interaction; socioeconomics; ecological systems; urban amenities; environmental impact assessment; what-if; decision-making; urbanisering; planeringsstödsystem; rumslig dynamisk modell; förändring av stadsmarkanvändning; rumslig analys; mänsklig-land interaktion; socioekonomi; ekologiska system; urbana bekvämligheter; miljökonsekvensbeskrivning; vad-om; beslutsfattande; Mark- och vattenteknik; Land and Water Resources Engineering;

    Sammanfattning : As global urbanization progresses, cities worldwide are growing in size, which leads to many economic, environmental, and management challenges. Recent advancements in spatial data analysis and algorithmic geography have also led to the development of various urban model-based planning support systems (PSS) for urban planning. LÄS MER

  5. 4. Predictive Modelling to Support Design and Manufacturing in Aerospace Engineering

    Författare :Siva Krishna Dasari; Abbas Cheddad; Lars Lundberg; Stan Matwin; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; surrogate modelling; defects classification; machine learning; aerospace; additive manufacturing; Computer Science; Datavetenskap;

    Sammanfattning : A crucial issue in the design of aircraft components is the evaluation of a large number of potential design alternatives.  This evaluation involves too expensive procedures, consequently, it slows down the search for optimal design samples. LÄS MER

  7. 5. Model-based head tracking and coding

    Författare :Jacob Ström; Stan Sclaroff; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : This thesis treats two topics in model-based coding; coding of facial textures (Part 1) and real-time head tracking (Part 2).In Part 1, it is shown that a face image can be efficiently coded using a parameterization based on geometrical normalization followed by Karhunen-Loeve transformation (KLT).
