2. 1. Social capital in healthcare : A resource for sustainable engagement in organizational improvement work

   Author : Marcus Strömgren; Lotta Dellve; Andrea Eriksson; David Bergman; Henna Hasson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Healthcare; social capital; engagement; leadership; sustainability; Sjukvård; socialt kapital; engagemang; ledarskap; hållbarhet; Technology and Health; Teknik och hälsa;

   Abstract : Social capital, work engagement, working conditions, and leadership are concepts that have been studied previously, but there is lack of knowledge about what processes promote sustainable organizational improvement work in hospitals, and specifically, what leads healthcare professionals to engage in clinical developments.The overall aim of this thesis is to increase knowledge of how social capital and engagement contribute to sustainable organizational improvement work in hospitals and how social capital and engagement are created during organizational improvement work.

4. 2. Some PDAE aspects of the numerical simulation of a CO2 heat pump

   Author : Magnus Strömgren; Michael Hanke; Claus Führer; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Numerical analysis; Numerisk analys;

   Abstract : We consider network modelling and numerical simulation of a simple CO2 heat pump consisting of a compressor, a valve and two heat exchangers. In a first step we investigate analytical and numerical properties of the heat exchanger model. READ MORE

5. 3. Modelling of Traffic Performance for Swedish Roads and Motorways

   Author : Per Strömgren; Harilaos Koutsopoulos; Nagui Rouphail; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rural highway; Intersection; Capacity; Critical gap; Flare; Micro simulation; Motorway; Ramp; Weaving; Merging; Queue; Delay; Over-saturated; Time-space; Roadwork zone; variable speed limit; harmonization; Transportvetenskap; Transport Science;

   Abstract : This thesis consists of five scientific articles oriented towards capacity. Managing capacity constraints with associated delays is a big issue at new design as well as at trimming existing traffic facilities. READ MORE

6. 4. Spatial diffusion of telemedicine in Sweden

   Author : Magnus Strömgren; Umeå universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Telemedicine; Spatial diffusion; Sweden; Northern Sweden; Information technology; Networks; Health care delivery;

   Abstract : “Telemedicine” denotes medicine at a distance using telecommunications and information technologies. The aim of the thesis is to reveal determinants and outcomes of telemedicine diffusion—that is, the spread of telemedicine in time and space. Telemedicine is examined both at the national level and in a regional case study. READ MORE

7. 5. Model predictions of turbulent gas-particle shear flows

   Author : Tobias Strömgren; Gustav Amberg; Arne V. Johansson; Martin Sommerfeld; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbulent gas-particle flows; modelling; turbophoresis; two-way coupling; particle-particle collisions; numerical simulations; Fluid mechanics; Strömningsmekanik;

   Abstract : A turbulent two-phase flow model using kinetic theory of granularflows for the particle phase is developed and implmented in afinite element code. The model can be used for engineeringapplications. However, in this thesis it is used to investigateturbulent gas-particle flows through numerical simulations. READ MORE
