1. 1. Prediction of Cooling Air Flow in Electric Generators

   Författare :Pirooz Moradnia; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; Multiple Reference Frame; PIV; Total Pressure Measurements; Electric Generator; Experimental Measurements; 5-hole Pressure Probe Measurements; Flow Prediction; OpenFOAM;

   Sammanfattning : The cooling air flow in hydro power electric generators is investigated experimentally and numerically. A fully predictive numerical approach is presented and validated, in which the inlet and outlet boundaries are eliminated from the computational domain. LÄS MER

3. 2. Multiple marketing channel conflict with a focus on the internet

   Författare :Lena Goldkuhl; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Industriell marknadsföring; Industrial Marketing;

   Sammanfattning : The emergence of electronic commerce has led more and more companies to, in addition to using resellers, add the Internet to sell directly to its end customers, something that inevitably will create channel conflict. The way companies handle such conflict is considered an important success factor. LÄS MER

4. 3. Autonomy and integrity : drivers of health care professionals dealing with multiple obligations

   Författare :Elsmari Bergin; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Professional development; middle managers; health care; conflict; autonomy; organizational change; integrity; professional identity; commitment; qualitative research;

   Sammanfattning : The medical services have undergone substantial changes over the past decades, and the design and content of health care have been determined by economic programmes, streamlining, and rationalization. The calls to cut costs and implement reorganizations have come largely from politicians and have been handled by middle and high-level managers. LÄS MER

5. 4. On Modeling and Stability Analysis of Grid-Connected Voltage Source Converters

   Författare :Hongyang Zhang; Stefan Östlund; Xiaoming Yuan; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low-inertia grid; multiple-input multiple-output MIMO ; single-input single-output SISO ; small-signal model; stability analysis; voltage source converters VSCs ; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : With increasing deployment of voltage source converters (VSCs) in the grid, instability phenomena due to converter--grid interactions have been observed. Modeling and stability analysis of grid-connected VSCs have become popular research topics. LÄS MER

7. 5. To be in‐between : The road to disability pension with reference to the Swedish social insurance system

   Författare :Berit Ydreborg; Kerstin Ekberg; Alf Bergroth; Linköpings universitet; []
