    Författare :Gani Bajraktari; Michael Henein; Krister Lindmark; Lars-Åke Brodin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heart failure; cardiac resynchronization therapy; predictors; echocardiography; total isovolumic time; six-minute walk test; left ventricular dyssynchrony;

    Sammanfattning : The objective of this thesis is to evaluate the use of Doppler echocardiography markers ofglobal dyssynchrony [total isovolumic time (t-IVT)] in the following 6 studies: 1) Its prognostic role in predicting cardiac events in patients undergoing CABG surgery,compared with conventional global systolic and diastolic measurements. 2) Its additional value in predicting six minute walk test (6-MWT) in patients with leftventricular (LV) ejection fraction (EF) .

  3. 22. Total Cost Analysis in Logistics : Practical Execution, Learning, and Teaching in Higher Education

    Författare :Björn Oskarsson; Maria Huge-Brodin; Jonas Hallström; Johan Woxenius; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : Cost is considered a crucial factor in much decision-making in private and public organisations. Therefore, the ability to calculate total estimated costs for different alternatives is important. However, such total cost analysis is a challenging task. LÄS MER

  4. 23. Hemi and total wrist arthroplasty

    Författare :Per Fischer; Kurt Pettersson; Marcus Sagerfors; Jan Fridén; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rheumatoid arthritis; Wrist; Arthroplasty; Implant survival; Biomechanics;

To report outcome following wrist revision arthroplasty. To evaluate a new radial wrist hemi arthroplasty (RWHA) design clinically and biomechanically. LÄS MER

  5. 24. Data-driven analysis of water and nutrient flows: Case of the Sava River Catchment and comparison with other regions

    Författare :Lea Levi; Vladimir Cvetkovic; Georgia Destouni; Roko Andričević; Ronny Berndtsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; River catchment; Transboundary; Hydro-climatic change; Total nitrogen; Total phosphorus; CMIP5; Land and Water Resources Engineering; Mark- och vattenteknik;

    Sammanfattning : A growing human population and demands for food, freshwater and energy are causing extensive changes in the water and biogeochemical cycles of river catchments around the world. Addressing and investigating such changes is particularly important for transboundary river catchments, where they impose additional risk to a region’s stability. LÄS MER

  7. 25. On the Optimization of Schedules of a Multitask Production Cell

    Författare :Karin Thörnblad; Göteborgs universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; mathematical optimization; flexible job shop scheduling; mixed integer linear programming MILP ; complexity analysis; mathematical modelling; production planning; multi-purpose machine; dispatching rule; priority function; total flowtime; total tardiness; release date; due date; due date;

    Sammanfattning : Volvo Aero has invested in a complex production cell containing a set of multipurpose machines. The problem of finding optimal schedules for this multitask cell is a complex combinatorial optimization problem which is recognized as a flexible job shop problem. This thesis proposes an approach to find such schedules using mathematical optimization. LÄS MER
