1. 1. 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

3. 2. Kommunala huvudmannastrategier för kostnadspress och utveckling : en studie av kommunal teknik

   Författare :Ola Mattisson; Företagsekonomiska institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; municipal engineering; strategy; Municipal responsible authority; process; competitive tendering; co-operation; innovation; cost reduction; Management of enterprises; Företagsledning; management;

   Sammanfattning : The aim of the study is to improve the understanding of strategy in politically governed organisations. From the perspective of a specific responsible authority the main purpose of the study is to describe and analyse how strategies emerge and develop. LÄS MER

4. 3. Health economic evaluation for evidence-informed decisions in low-resource settings : the case of Antenatal care policy in Rwanda

   Författare :Regis Hitimana; Anni-Maria Pulkki-Brännström; Lars Lindholm; Gunilla Kranz; Peter C. Smith; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antenatal; maternal; cost; cost-effectiveness; ultrasound; EQ-5D-3L; Low-income countries; Public health; folkhälsa;

   Sammanfattning : Introduction: The general aim of this thesis is to contribute to the use of health economic evidence for informed health care decisions in low-resource settings, using antenatal care (ANC) policy in Rwanda as a case study. Despite impressive and sustained progress over the last 15 years, Rwanda’s maternal mortality ratio is still among the highest in the world. LÄS MER

5. 4. Drag reduction using plasma actuators

   Författare :Romain Futrzynski; Gunilla Efraimsson; P. Henrik Alfredsson; Charles Mockett; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flow control; drag reduction; plasma actuator; DMD; LES; optimization; pulsating flow; strömningskontroll; motståndsminskning; plasma ställdon; DMD; LES; optimering; pulserande flöde; Engineering Mechanics; Teknisk mekanik;

   Sammanfattning : This thesis is motivated by the application of active flow control on the cabin of trucks, thereby providing a new means of drag reduction. Particularly, the work presented strives to identify how plasma actuators can be used to reduce the drag caused by the detachment of the flow around the A-pillars. LÄS MER

7. 5. Hydrogen in the European energy system - The cost dynamics and the value of time-shifting electricity generation

   Författare :Simon Öberg; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cost; energy systems modeling; Hydrogen; gas turbine; system dynamics; time-shifting;

   Sammanfattning : If the European Union is to become climate-neutral by Year 2050, as envisioned in the European Green Deal, the European energy system must undergo an unprecedented transformation towards eliminating its carbon emissions. For this transition, renewable electricity plays a central role, not only in replacing the current fossil-based electricity generation, but also in promoting the electrification of other sectors, such as transport and industry, sectors which are currently based on fossil fuels.
