2. 1. Firefighters' physical work capacity

   Author : Ann-Sofie Lindberg; Christer Malm; Juha Oksa; Desiree Gavhed; Peter Krustrup; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physical demands; performance; work capacity; aerobic fitness; anaerobic fitness; muscle strength; muscle endurance; balance; ergonomics; physical testing; SIMCA;

   Abstract : The overall aim of this thesis was to identify valid, simple, and inexpensive physical tests that can be used for evaluation of firefighters’ physical work capacity. Paper I included fulltime- and part-time firefighters (n = 193), aged 20-60 years. READ MORE

4. 2. Moisture Influence on Structural Behaviour of Pavements : Field and Laboratory Investigations

   Author : Farhad Salour; Sigurdur Erlingsson; Guy Doré; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Falling Weight Deflectometer FWD ; backcalculation; unbound material; subgrade; seasonal variation; moisture content; spring-thaw; drainage; pavement stiffness; field test; pavement instrumentation; resilient modulus; permanent deformation; repeated load triaxial test; unsaturated soil; matric suction.; Civil and Architectural Engineering; Byggvetenskap; Transportvetenskap; Transport Science;

   Abstract : The structural behaviour of pavements in cold regions can considerably be affected by seasonal variation in environmental factors such as temperature and moisture content. Along with the destructive effect of heavy traffic loads, climatic and environmental factors can considerably contribute to pavement deterioration. READ MORE

5. 3. Concrete Bridges : Improved Load Capacity

   Author : Jonny Nilimaa; Terje Kanstad; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

   Abstract : There are many beautiful old structures around the world, some of which were designed for completely different purposes than their current applications. For example, Swedish railway bridges were only designed to carry axle loads up to 200 kN in the beginning of the 20th century, while modern loads can be twice as high. READ MORE

6. 4. Capturing the Operational Improvement Potential of Production Systems

   Author : Richard Hedman; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Capacity; Productivity; Capacity utilization;

   Abstract : The operational level is where a company’s manufacturing strategy becomes reality and where customer orders are fulfilled through transforming raw materials into finished goods. The research presented here examines the productivity and capacity of operational processes in manufacturing firms. READ MORE

7. 5. Voltage Stability Simulations Using Detailed Models Based on Field Measurements

   Author : Daniel Karlsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; capacity limits; field measurements; dynamic load models; on-load tap-changer control system; voltage stability; simulations;

   Abstract : This dissertation deals with voltage stability simulations, including dynamic load models, on-load tap-changer control system dynamics and generator reactive power output capacity limits. The simulations are based on sequential solving of ordinary load flow cases augmented with dynamic models. READ MORE
