  1. 21. Mission Concept for a Satellite Mission to Test Special Relativity

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Volkan Anadol; [2016]
    Keywords : BOOST; Special Relativity; Kennedy Thorndike; Eclipse duration; Ground visibility; Downlink feasibility; 3-axis stabilization; Spin stabilized satellite; Solar array estimation; Battery size estimation.;

    Abstract : In 1905 Albert Einstein developed the theory of Special Relativity. This theory describes the relation between space and time and revolutionized the understanding of the universe. While the concept is generally accepted new experimental setups are constantly being developed to challenge the theory, but so far no contradictions have been found. READ MORE

  3. 22. Realization of a downscaled pendulum-arm suspended forwarder

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Petter Norder; Björn Sandegård; [2015]
    Keywords : Scale model; Skogforsk; Pendulum arm suspension; Skalmodell; Skogforsk; Pendelarmsdämpning;

    Abstract : Almost all logging in Sweden is carried out by the Cut-To-Length method. The method is carried out by two machines, a harvester and a forwarder. The forwarder transports the cut logs from the forest to a landing area for further transportation. READ MORE

  4. 23. Multi-objective optimization and performance evaluation of active, semi-active and passive suspensions for forestry machines

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Federico Baez; [2014]
    Keywords : Forestry machine; suspension; multi-objective optimization; forwarder; pendulum arm; active; semi-active; passive; XT28; Multibody Dynamics; soil-friendly; off-road; Skogsmaskin; fjädring; optimering; skotare; pendelarm; aktiv; semi-aktiv; passiv; XT28; flerkroppsdynamik; markvänlig; off-road;

    Abstract : The development of forestry machines is currently heading towards new solutions that reduce their impact on the environment and in particular on the soft forest soil in which the machines operate. The terrain conditions that forestry machines encounter in their regular duties can be very rough, and if the vehicle-ground interaction is not properly controlled cumulative damage can progressively aggravate these conditions and potentially render a route or a zone impracticable, apart from causing a detrimental effect in the forest environment.

  6. 25. Pile – Soil Interaction during Vibratory Sheet Pile Driving : a Full Scale Field Study

    University essay from KTH/Jord- och bergmekanik

    Author : Claire Guillement; [2013]
    Keywords : Ground vibrations; vibratory driving; sheet pile; full-scale field study; soil instrumentation; sheet pile instrumentation.;

    Abstract : Urban construction sites require strict control of their environmental impact, which, for vibratory sheet pile driving, can include damage to nearby structures due to ground vibrations. However, the lack of knowledge concerning the generation of soil vibrations makes the prediction of ground vibration levels difficult. This MSc. READ MORE
