  1. 26. A Life on the Ocean Wave - Exploring the interaction between the crew and their adaption to the development of the work situation on board Swedish merchant ships

    Författare :Monica Lundh; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; engine room; evacuation; work environment; Keywords: Automation; role conflict; ships; stress; engine officers;

    Sammanfattning : ABSTRACTWorking on board merchant ships implies being a part of an isolated context in a multi-cultural arena and spending a lot of time away from family and friends. The shipping industry has during the latest decades undergone major changes due to technical development, automation and increased requirements for profitability and competitiveness. LÄS MER

  3. 27. Unpacking Sanitation Planning Comparing Theory and Practice

    Författare :Jennifer R Mc Conville; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Participation; Sustainability; Urban; Procedural planning theory; Decision-making; Sanitation; Process; Planning practice;

    Sammanfattning : Lack of proper sanitation is linked to significant negative impacts on environmental and public health, economy, and human dignity. Despite the efforts made to reach the United Nations Millennium Development Goals, the world will miss its target of halving the percentage of people without access to improved sanitation by 2015; and there is general agreement within the field of sanitation that the sector has failed to deliver substantial improvements to the most needy.

  4. 28. CFD of Air Flow in Hydro Power Generators

    Författare :Pirooz Moradnia; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; OpenFOAM; MultipleReferenceFrame; CFD; Generator; Launder-Sharma k-ε;

    Sammanfattning : The air flow through a generator has been numerically investigated with different rotor and stator designs to give a better understanding of the flow for cooling purposes. A simple rotor design has been chosen to start with, and modified through a set of changes, where stepwisemodifications have been imposed to the design of the rotor and the stator. LÄS MER

  5. 29. Microsensors for in situ electron microscopy applications

    Författare :Alexandra Nafari; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; capacitive read-out; Microsensors; In situ TEM; TEM-AFM; TEM-Nanoindenter; AFM; nanoscale characterisation; MEMS; Nanoindentation; piezoresistive read-out;

    Sammanfattning : With the ongoing miniaturisation of devices, the interest in characterising nanoscale physical properties has strongly increased. To further advance the field of nanotechnology new scientific tools are required. LÄS MER

  7. 30. Energy Efficient Protocols for Active RFID

    Författare :Björn Nilsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; wake-up radio; energy consumption; energy efficient; Active RFID; protocol; RFID; throughput; back-off; RFID-system; delay;

    Sammanfattning : Radio frequency identification (RFID) systems come in different flavours; passive, active, semi-passive, or semi-active. Those different types of RFID are supported by different, internationally accepted protocol standards as well as by several accepted proprietary protocols. LÄS MER
