4. 2. Finite Element Procedures in Modelling the Dynamic Properties of Rubber

   Author : Anders K Olsson; Byggnadsmekanik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; akustik; vibration and acoustic engineering; Materiallära; materialteknik; Mechanical engineering; hydraulics; vacuum technology; Material technology; dynamic; amplitude; frequency; Technological sciences; Teknik; FEM; rubber; vibrationer; vakuumteknik; Maskinteknik; hydraulik;

   Abstract : Rubber is not only a non-linear elastic material, it is also dependent on strain rate, temperature and strain amplitude. The non-linear elastic property and the strain amplitude dependence give a non-linear dynamic behavior that is covered by the models suggested in this thesis. READ MORE

5. 3. Mehanics of Rock Fragmentation Static and Dynamic Laboratory Testing Applied to Aggregate Production

   Author : Bahman Bohloli; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; anisotropy; aggregates; rock failure; saturation; Brazilian test; dynamic tensile strength; Hopkinson pressure bar; fragmentation; rock fines; crushing;

   Abstract : Knowing the strength properties of rocks is essential for calculating the stability of natural slopes, constructions in and on rock, excavations, blasting geometry, crushing, and drilling. When rock and rock masses are subjected to either dynamic or static loads, the tensile strength is determined by tests appropriate to the load type. READ MORE

6. 4. BACK TO ONESELF Sensory Motor Learning applied in patients with nonspecific chronic low back pain

   Author : Christina Schön-Ohlsson; Göteborgs universitet; []
   Keywords : Chronic nonspecific low back pain; Sensory Motor Learning; SML; Posturo-Locomotion-Manipulation PLM test; Qualitative method; Focus group study; Health promotion; Feldenkrais method; Exercise therapy;

   Abstract : Back pain is an endemic problem affecting one in five adults every year. Even though only 10 % of all cases of back pain become chronic it is one of the largest health problems in industrialized societies. READ MORE

7. 5. A Factor Analytical Approach to Dynamic Panel Data Models

   Author : Milda Norkute; Nationalekonomiska institutionen; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Dynamic panel data models; Factor analytical method; Bias; Incidental trends; MA errors; Factor-GMM;

   Abstract : This thesis deals with the development and application of new estimation approaches based on factor analysis for estimation and inference in dynamic panel data models with fixed-effects. A new factor analytical method (FA) for the estimation of fixed-effects dynamic panel data models is proposed in Bai ("Fixed-Effects Dynamic Panel Models, A Factor Analytical Method". READ MORE
