1. 1. Biomechanical consequences of gait impairment at the ankle and foot : Injury, malalignment, and co-contraction

   Författare :Ruoli Wang; Elena Gutierrez-Farewik; Eva Broström; Eriksson Anders; Ilse Jonkers; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; muscle function; gait analysis; induced acceleration; foot kinematics; dynamic joint stiffness;

   Sammanfattning : The human foot contributes significantly to the function of the whole lower extremity during standing and locomotion. Nevertheless, the foot and ankle often suffer injuries and are affected by many musculoskeletal and neurological pathologies. LÄS MER

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Volume; Minimization criterion; Determinant; Rank deficient matrix; Reduced rank regression; System identification; Rank reduction; Volume minimization; General algorithm; Handwritten digit classification; Tensors; Higher order singular value decomposition; Tensor approximation; Least squares; Tucker model; Multilinear algebra; Notation; Contraction; Tensor matricization; Newton s method; Grassmann manifolds; Product manifolds; Quasi-Newton algorithms; BFGS and L-BFGS; Symmetric tensor approximation; Local intrinsic coordinates; Global embedded coordinates; ; Numerical analysis; Numerisk analys;

   Sammanfattning : In many fields of science, engineering, and economics large amounts of data are stored and there is a need to analyze these data in order to extract information for various purposes. Data mining is a general concept involving different tools for performing this kind of analysis. LÄS MER

4. 3. Lp-contractivity of Semigroups Generated by Linear Partial Differential Operators

   Författare :Mikael Langer; Stig Larsson; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : This thesis is devoted to the study of contraction semigroups generated by linear partial differential operators. It is shown that linear partial differential operators of order higher than two cannot generate contraction semigroups on (LP)N for p ∈ [1, oo) unless p = 2. LÄS MER

5. 4. Electromyography and bite force studies of muscular function and dysfunction in masticatory muscles

   Författare :Catharina Hagberg; []
   Nyckelord :Electromyography; bite force; contraction; isometric; masticatory muscles; mastication; intramuscular injections;

   Sammanfattning : Electromyographic (EMG) activity versus bite force was studied during a gradually increased isometric contraction up to maximal effort for patients with painful masseter muscles and referents. The masseter muscle, the anterior temporal muscle and the descending part of the trapezius muscle were chosen for the recordings. LÄS MER

7. 5. The mechanisms controlling heat and mass transfer on frying of beefburgers

   Författare :Bea Kovácsné Oroszvári; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; permeability; porosity; contraction; frying; beefburger; heat and mass transfer;

   Sammanfattning : The aim of the present work was to gain better understanding of the mechanisms controlling heat and mass transfer during thermal processing of beefburgers. The effects of different factors such as the chemical composition and comminution of the meat raw material, the pan temperature and the meat patty diameter on the characteristics of heat and mass transfer were studied.
