  1. 1. Groin hernias and unmet need for surgery in Uganda : Epidemiology, mosquito nets and cost-effectiveness

    Författare :Jenny Löfgren; Andreas Wladis; Pär Nordin; Birger Forsberg; Thomas Weiser; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Global surgery; groin hernia; groin hernia surgery; hernia epidemiology; low cost surgery; cost-effectiveness; kirurgi; Surgery;

    Sammanfattning : Background Surgery has traditionally been considered more expensive than many other health care interventions and with little impact on the burden of disease in a global perspective. One of the reasons behind this misconception is that the effects of surgical conditions and their treatment have not been factored into the equation. LÄS MER

  3. 2. Logistics Systems for Recycling - Efficient Collection of Household Waste

    Författare :Marianne Jahre; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; waste col lection systems; reverse distribution; green logistics; collection; reverse logistics; recycling; environment; waste;

    Sammanfattning : This dissertation investigates collection and recycling of household waste with focus on packaging materials. The purpose is how to describe and explain the d esign of a collection system according to different system environments in orde r to achieve high logistics performance in terms of low cost and high service.

  4. 3. Cost efficency of nonresponse rate reduction efforts : an evaluation approach

    Författare :Sara Westling; Bengt Swensson; Risto Lehtonen; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nonresponse bias; follow-ups; response distribution; resource allocation; cost efficiency; evaluation; nonresponse error; Monte Carlo simulations; Statistics; Statistik; Statistics; Statistik;

    Sammanfattning : Nonresponse, the failure to obtain complete measurement on all sample elements, is an increasing problem in sample surveys. Efforts to reduce the nonresponse rate are expensive and their effect may not be as desired. LÄS MER

  5. 4. Road Design for Future Maintenance : Life-cycle Cost Analyses for Road Barriers

    Författare :Hawzheen Karim; Björn Birgisson; Ulf Isacsson; Rolf Magnusson; Robert Thomson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road maintenance; road management; road planning; road design; life-cycle cost; road barrier; guardrails; cable barrier; road traffic injuries; barrier collisions and barrier repair costs.; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur; Vägprojektering för minskade drift- och underhållskostnader;

    Sammanfattning : The cost of a road construction over its service life is a function of design, quality of construction as well as maintenance strategies and operations. An optimal life-cycle cost for a road requires evaluations of the above mentioned components. LÄS MER

  7. 5. Designing Urban Road Congestion Charging Systems : Models and Heuristic Solution Approaches

    Författare :Joakim Ekström; Jan Lundgren; Anders Karlström; Linköpings universitet; []
    Nyckelord :transport modeling; congestion pricing; network design; bi-level optimization; toll locations; traffic assignment; user equilibrium; collection cost; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The question of how to design a congestion pricing scheme is difficult to answer and involves a number of complex decisions. This thesis is devoted to the quantitative parts of designing a congestion pricing scheme with link tolls in an urban car traffic network. LÄS MER
