1. 1. Fatigue and Fracture of High-Strength Steels : Improving Reliability in Strength Assessment

   Författare :Gustav Hultgren; Zuheir Barsoum; Rami Mansour; Torbjörn Narström; Gary Marquis; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-Strength Steel; Quality assurance; Probabilistic modeling; Fatigue; Fracture mechanics; Farkostteknik; Vehicle and Maritime Engineering;

   Sammanfattning : Structural steel plays a fundamental role in the heavy industry, serving as a key material for numerous load-bearing products and equipment. Its widespread use is attributed to its robustness, resistance to wear, ease of use in construction, and cost-effectiveness. LÄS MER

3. 2. Ultimate and Residual Strength Assessment of Ship Structures

   Författare :Artjoms Kuznecovs; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ship structures; collision; corrosion; residual strength; ultimate strength; age-related degradation; nonlinear FEA; Smith method;

   Sammanfattning : The prevention of ship structural failures and reduction of accident consequences contribute to increased safety at sea and reduced environmental impact. A need for reliable and efficient ship designs facilitates knowledge accumulation and the development of tools for the assessment of hull structural responses to acting loads. LÄS MER

4. 3. Strategies for exercise assessment and training in patients with chronic obstructive pulmonary disease

   Författare :Tania Janaudis-Ferreira; Karin Wadell; Margareta Emtner; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; COPD; exercise; assessment; muscle strength; arm function; Physiotherapy; Sjukgymnastik fysioterapi; lungmedicin; Lung Medicine;

   Sammanfattning : Rationale: Chronic obstructive pulmonary disease (COPD) is not only a common lung disease but is a major cause of morbidity and mortality worldwide. Pulmonary rehabilitation (PR) helps optimize function and independence by increasing exercise capacity, reducing symptoms and improving health related quality of life (HRQL). LÄS MER

5. 4. Reliability-based assessment procedures for existing concrete structures

   Författare :Joakim Jeppsson; Avdelningen för Konstruktionsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete; reliability theory; service life; assessment; monitoring; hydraulic engineering; Civil engineering; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

   Sammanfattning : A feasibility study of reliability theory as a tool for the assessment of present safety and residual service life of damaged concrete structures has been performed in order to find a transparent methodology for the assessment procedure. It is concluded that the current guidelines are open to interpretation and that the variation in the results obtained regarding the structural safety is too great to be acceptable. LÄS MER

7. 5. Kinetic chain weight training, strength assessment, and functional performance testing: with reference to sports and rehabilitation

   Författare :Jesper Augustsson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; open kinetic chain; closed kinetic chain; weight training; strength assessment; functional tests; anterior cruciate ligament; reconstruction; fatigue;

   Sammanfattning : The overall purpose of the studies was to obtain knowledge about physical performance in healthy individuals and patients after anterior cruciate ligament (ACL) reconstruction. Data are presented that concerns closed and open kinetic chain exercise, adaptive response to weight training, the methodology of muscle strength assessment, and the development of a functional testing protocol performed under conditions of fatigue.
