  1. 11. Assisted Tele-Remote Control of Wheel Loaders in Underground Mining

    Författare :Siddharth Dadhich; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Sammanfattning : Tele-remote operation of mobile earth-moving machines in underground mines supported byoperator assistance functions is attractive for safety and productivity reasons. This way, operatorscan avoid hazardous underground environments with poor air quality and the productivitycan, in principle, be improved by saving the time required to commute drivers to and fromthe operational areas.

  3. 12. Improvement of Labour Performance and Productivity in Uganda´s Building Industry

    Författare :Henry Mwanaki Alinaitwe; Byggproduktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; performance improvement; Labour productivity; building industry; Uganda;

    Sammanfattning : Productivity of labour is particularly important especially in developing countries where most of the building work is still carried out on manual basis. Previous research has pointed out that productivity in the building industry is low and in some cases declining. LÄS MER

  4. 13. Spaces within Spaces : The Construction of a Collaborative Reality

    Författare :Hillevi Sundholm; Carl Gustaf Jansson; Yvonne Rogers; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Co-located collaboration; Distributed collaboration; Teamwork; Interactive spaces; Space; Computer and systems science; Data- och systemvetenskap; Man-Machine-Interaction MMI ; människa-maskin-interaktion MMI ;

    Sammanfattning : This thesis is about collaborative activities in interactive spaces. These spaces are characterized by having shared, large displays in combination with private displays and software tools that facilitate a fluent sharing of information between people and their resources.

  5. 14. Quantifying Operability of Working Machines

    Författare :Reno Filla; Jan-Ove Palmberg; Kjell Ohlsson; Jonas Larsson; Linköpings universitet; []
    Nyckelord :Operability; machine harmony; operator workload; control effort; simulation; operator model; human operator; working machines; construction equipment; wheel loaders; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : In working machines the human operator is essential for the performance of the total system. Productivity and energy efficiency are both dependent not only on inherent machine properties and working place conditions, but also on how the operator manoeuvres the machine. LÄS MER

  7. 15. Kinematic Control of Redundant Knuckle Booms with Automatic Path Following Functions

    Författare :Björn Löfgren; Jan Wikander; Arto Finland Helsinki University of Technology Visala; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydraulic manipulator; redundancy; kinematic control; local optimization; knuckle boom; forest machine; forwarder; boom tip control; joystick control; simulations; path following; Construction engineering; Konstruktionsteknik;

    Sammanfattning : To stay competitive internationally, the Swedish forestry sector must increase its productivity by 2 to 3% annually. There are a variety of ways in which productivity can be increased. One option is to develop remote-controlled or unmanned machines, thus reducing the need for operator intervention. LÄS MER
