  2. 1. Development of a Generic Model for Life Cycle Inventory and Environmental Assessment of Upstream Processes for Electronic Products

    Author : Anders Andrae; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System-In-a-Package; electronic products; upstream processes; life cycle inventory; life cycle assessment;

    Abstract : The goal with the present thesis is to develop tools, methods and models to assess the upstream processes in the life cycle assessment (LCA) methodology for current and new electronic products. The goal is to get a better understanding on how to collect data to be used in a life cycle inventory (LCI) and use life cycle approaches to environmentally assess the electronics. READ MORE

  4. 2. Flow preferences of upstream migrating Atlantic salmon (Salmo salar)

    Author : Dan-Erik Lindberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : On their way from the sea to their spawning grounds in rivers, Atlantic salmon are often delayed or hindered by dams or other obstructions. Building a fishway can save a population that would otherwise go extinct. READ MORE

  5. 3. Environmental Life-cycle Assessment in Microelectronics Packaging

    Author : Anders Andrae; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System-In-a-Package; microelectronics packaging; data collection; attributional environmental life-cycle assessment; uncertainty analysis; upstream processes; consequential life-cycle assessment; environmental life-cycle inventory; microelectronic products;

    Abstract : An increased understanding of the application of environmental Life-Cycle Assessment (LCA) methodologies in the microelectronics packaging area should help in developing environmentally sound product systems. The aim of the present thesis is to increase the knowledge of using LCA tools, methods and models, in application to current and new microelectronic products. READ MORE

  6. 4. Aerodynamic Design and Installation Effects of Automotive Electric Cooling Fans

    Author : Debarshee Ghosh; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blade Element Momentum BEM ; low-pressure axial fans; electric cooling fans; automotive thermal management; CFD simulations; upstream blockage; fans in parallel;

    Abstract : Electric cooling fans play a crucial role in automotive thermal management. They generate the airflow required for heat rejection from the expended coolant circulating within the heat exchanger. This thesis focuses on the aerodynamic design and installation effects of electric cooling fans or "E-fans". READ MORE

  7. 5. Advancement of sensor technology for monitoring and control of upstream bioprocesses

    Author : Judit Randek; Carl-Fredrik Mandenius; Gerald Striedner; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In bioprocesses, the upstream process part with cultivation and harvesting steps has decisive influence on the final process outcome, including the quality of the product, the productivity and the yield. To ensure stable product quality of biopharmaceuticals, the U.S. READ MORE
