  2. 1. Information Visualization Using Transparent Displays in Mobile Cranes and Excavators

    Author : Taufik Akbar Sitompul; Rikard Lindell; Björn Lisper; Philippe Palanque; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Abstract : Operating heavy machinery, such as mobile cranes and excavators, is a complex task. While driving the machine, operators are also performing industrial tasks, e.g. lifting or digging, monitoring the machine’s status, and observing the surroundings. READ MORE

  5. 3. Concepts for mechanized tree planting in southern Sweden

    Author : Back Tomas Ersson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The underlying reason for mechanizing tree planting in southern Sweden is the biologically good planting results produced by today's tree planting machines. Nevertheless, the productivity of these tracked excavators with crane-mounted tree planting devices is too low for them to compete economically with manual planting. READ MORE

  6. 4. A 3D Digital Approach to the Stylistic and Typo-Technological Study of Small Figurines from Ayia Irini, Cyprus

    Author : Valentina Vassallo; Antikens kultur och samhällsliv; []
    Keywords : HUMANIORA; HUMANITIES; Cypriot archaeology; Coroplastic; Figurines; 3D shape analysis; 3D GIS; Analytical investigation; Semantics;

    Abstract : The thesis aims to develop a 3D digital approach to the stylistic and typo-technological study of coroplastic, focusing on small figurines. The case study to test the method is a sample of terracotta statuettes from an assemblage of approximately 2000 statues and figurines found at the beginning of the 20th century in a rural open-air sanctuary at Ayia Irini (Cyprus) by the archaeologists of the Swedish Cyprus Expedition.

  7. 5. On Electrified Fluid Power Systems in Mobile Machinery

    Author : Samuel Kärnell; Liselott Ericson; Petter Krus; Rudolf Scheidl; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid power; Electrification; Variable displacement; Pump-controlled systems;

    Abstract : High power density in combination with flexible power distribution possibilities and extreme robustness are reasons why fluid power has been the preferred technology in mobile machinery, such as excavators and cranes, since the mid-20th century. In principle, the machines have been powered by a combustion engine which powers a pump, with the output from the pump being distributed to different functions via valves. READ MORE
