  2. 16. LCA and LCCA in the design of geotechnical engineering works

    Author : Ida Samuelsson; Stefan Larsson; Johan Spross; Rasmus Rempling; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Life Cycle Assessment; Life Cycle Cost Analysis; climate impact; costs; geotechnical engineering; Livscykelanalys; Livscykelkostnadsanalys; klimatpåverkan; kostnader; geoteknik; Soil and Rock Mechanics; Jord- och bergmekanik;

    Abstract : Geotechnical engineering works are part of almost all construction and infrastructure projects. The geotechnical engineering work contributes to the impact on the environment and gives rise to costs throughout its life cycle. READ MORE

  4. 17. Costs in Swedish Public Transport : An analysis of cost drivers and cost efficiency in public transport contracts

    Author : Andreas Vigren; Svante Mandell; Johan Holmgren; Statens väg- och transportforskningsinstitut; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cost; Increase; Efficiency; Contract; Procurement; Public transport; 02 Road: Economics; 02 Road: Economics; Transportvetenskap;

    Abstract : During the last seven years, the total cost for Swedish public transport provision has increased by over 30 percent in real terms according to figures from the government agency Transport Analysis. A similar pattern is found if considering a longer time span. READ MORE

  5. 18. Strategies for Reduced Energy Use and Cost in Pulp and Paper Mills by Energy Integration of the Paper Drying Process

    Author : Kristian Lindell; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Paper; Pappers- och massateknik; pulp and paper technology; Wood; Energiforskning; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Combined dryer; Energy research; Black liquor gasification; Heat recovery; Secondary energy; Co-generation; Costs; Energy; Drying;

    Abstract : The cost of energy for drying paper is substantial for the pulp and paper industry, and studies of various strategies for energy cost reductions such as increased energy efficiency, increased heat recovery from the exhaust drying air and reduced cost of the process heat are presented in this thesis. The energy use and cost studies were performed using a block-model based simulation tool developed for this specific purpose. READ MORE

  6. 19. Sulphur Regulations for Shipping – Why a Regional Approach?: Scientific and Economic Arguments in IMO Documents 1988-1997

    Author : Erik Svensson; Chalmers tekniska högskola; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; costs; framing; shipping; SECA; distribution; environmental; policy environment; international; MARPOL; conceptual lens; IMO; Annex VI; regional approach; economic interests; directional problem; benefits; policy-making; SOx; science;

    Abstract : Some environmental issues for shipping are regulated globally with uniform standards and others with stricter regulations in specific areas. This thesis aims to provide an understanding of why a regional approach was chosen with SOx Emission Control Areas (SECAs) as the main form of control of sulphur oxide emissions from international shipping, with explanations based on documents from negotiations within the International Maritime Organization (IMO) during 1988-1997.

  7. 20. Computer-assisted surgery in children

    Author : Magnus Anderberg; Lund Pediatrik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; minimally invasive; learning curve; laparoscopy; fundoplication; da Vinci® Surgical System; costs; Children; computer-assisted; paediatric surgery; robot; robotic surgery;

    Abstract : Although positive in terms of patient trauma and recovery time, minimally invasive surgery has several technical drawbacks compared with open surgery. The new da Vinci® Surgical System from Intuitive Surgical® offers technical innovations aiming at overcoming these drawbacks and at improving the surgeon’s operating skills, such as the improved 3-D vision, tremor reduction and flexible instruments with a more natural and intuitive range of motion.
