2. 1. Product innovation in small established enterprises : Managing processes and resource scarcity

   Author : Lars Löfqvist; Lars Bengtsson; Jenny Janhager-Stier; Matti Kaulio; Helena Forsman; KTH; []
   Keywords : innovation process; small enterprises; product innovation; resources; resource scarcity; SMEs; bootstrapping; cash flow; commercialization; design process; lead users; motivation; NPD; small companies; small firms; innovation management; Penrose; resource dependence theory;

   Abstract : This thesis examines product innovation processes in small established enterprises. The research questions are: (1) what motivates small established enterprises to innovate, (2) how do small established enterprises perform product innovation, and (3) how do small established enterprises manage resource scarcity in their product innovation processes? To answer the research questions, a multiple case study approach was chosen with three small established enterprises as cases and different product innovation processes as embedded units of study.

4. 2. Flow-oriented studies for environmental management by local authorities : experiences from a regional substance flow analysis

   Author : Annica Lindqvist-Östblom; Linköpings universitet; []
   Keywords : flow-oriented studies; material flow analysis; substance flow analysis; interpretation; local authorities; regional authorities; environmental management; cadmium; sewage;

   Abstract : This thesis focuses on the issue of how to perform flow-oriented studies in order to become more useful for and adapted to local/regional authorities. Compared to traditional environmental monitoring and measurement of the state of the environment, flow-oriented studies are an attempt to broaden the approach to environmental concerns. READ MORE

5. 3. Resource and Environmental Impacts of Resource-Efficiency Measures Applied to Electronic Products

   Author : Hampus André; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; scarce metals; life cycle assessment; resource-efficiency; electronic products; resource depletion; circular economy; metal resource use;

   Abstract : Natural resources such as ecosystems, land, water and metals underpin the functioning of economies and human well-being, and are becoming increasingly scarce due to growth in population and affluence. Metals are increasingly demanded for their specific properties as modern technology develops. READ MORE

6. 4. Numerical investigation of the flow and instabilities at part-load and speed-no-load in an axial turbine

   Author : Jelle Kranenbarg; Michel Cervantes; Lisa Prahl Wittberg; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Speed-no-load; vortical flow structures; flow instabilities; rotating stall; mitigation; independent guide vanes; axial turbine; swirling flow; off design operation; URANS; parametric study; blade clearance; head losses; diffusor; GEKO model; flow separation; hydraulic turbine; Strömningslära; Fluid Mechanics;

   Abstract : Global renewable energy requirements rapidly increase with the transition to a fossil-free society. As a result, intermittent energy resources, such as wind- and solar power, have become increasingly popular. However, their energy production varies over time, both in the short- and long term.

7. 5. Hydrokinetic Resource Assessment : Measurements and Models

   Author : Emilia Lalander; Mats Leijon; Mitsuhiro Kawase; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The conversion of kinetic energy in water currents into electricity has gained great attention the past years. The conversion systems are stand-alone units that typically consist of a turbine, driven by the water stream, with a generator connected to it. READ MORE
