  2. 1. Large Area Propellers

    Author : Daniel Knutsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; propeller hull interaction; propulsive efficiency; large propellers;

    Abstract : Even if shipping is the most energy efficient and inexpensive way of transporting large volumes of goods across the world, it still could be significantly improved with respect to energy efficiency.In this thesis, propulsive efficiency is improved by moving the propeller backwards from its original position and increasing its diameter.

    Abstract : Large area flat displays are nowadays considered being a commodity. After the era of bulky CRT TV technology, LCD and OLED have taken over as the most prevalent technologies for high quality image display devices. READ MORE

  7. 5. Towards Large-Area Electronic Systems Using Non-Conventional Substrate and Conductor Materials

    Author : Xiaotian Li; Johan Sidén; Henrik Andersson; Leena Ukkonen; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Non-conventional materials; large-area electronics;

    Abstract : Flexible circuits, also known as flexible printed circuit boards, were originally developed in the 1950s for interconnection between multiple electronic devices when flexibility and movement were required. Nowadays, flexible circuits can be used for implementing electronic systems much more complicated than just interconnections. READ MORE
