  1. 1. Unique shape of Trichosanthes pilosa seed and its biological meaning

    University essay from Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Author : Akari Bergquist; [2023-12-07]
    Keywords : ;

    Abstract : Trichosanthes.pilosa(=T. pilosa) commonly known as Japanese snake gourd is a plant in Cucurbitaceae family. They are adapted to grow in tropical monsoon, wet tropical, and humid subtropical climates across regions in East Asia, Southeast Asia, Northeast India, and North Australia. READ MORE

  3. 2. Design of a vacuum chamber for cathode testing and low power Hall Effect Thrusters : Collaborative project with OHB Sweden AB

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Andrea Martinez Sanz; [2023]
    Keywords : Vacuum chamber; adaptability; hollow cathode test; fluid ground support equipment; low power Hall Effect Thrusters test; Vakuumkammare; anpassningsförmåga; ihålig katod testa; flytande markstödutrustning; låg effekt Hall Effect Thrusters testa;

    Abstract : Testing of hardware to be used in space sometimes involves using vacuum chambers. The need to test hollow cathodes, used as neutralizers for some Electric Propulsion Thrusters, and low power Hall Effect Thrusters at OHB Sweden requires a vacuum chamber to be upgraded. READ MORE

  4. 3. Evaluating the performance of cone crushers under various feeding conditions using DEM and coupled DEM-MBS simulations

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : John Larsson; [2023]
    Keywords : Discrete Element Method; DEM; Cone Crusher; Segregation; Co-Simulation; Multi-body Dynamics; MBD;

    Abstract : Cone crushers are used in both the construction and mining industries for the production of aggregates and extraction of ores. Aggregates are used when building for example houses, roads and railways, hence the cone crushers are a vital part of modern society. READ MORE

  5. 4. Low-Temperature Thermal Control System for an Environmental Chamber

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Aleksis Pauls Lindemanis; [2022]
    Keywords : Space simulator; environmental chamber; thermal control design; thermal conductivity in bolted joints; thermal simulations; Mars climate; Carbon dioxide sublimation and deposition;

    Abstract : In spite of significant reduction of cost associated with launching a spacecraft, launching deep space exploratory missions are yet to be accessible to most universities and researchers. A solution to testing scientific hypotheses and verifying technologies for space is the use of environmental chambers, also know as space simulators, - vacuum chambers, which replicate the space environment.

  6. 5. Extraction of Loudspeaker- and room impulse responses under overlapping conditions

    University essay from Uppsala universitet/Signaler och system

    Author : Felix Gustafsson; [2022]
    Keywords : Signal processing; Optimization; Acoustics; Dereverberation; Sparse deconvolution; Multipath propagation;

    Abstract : A loudspeaker is often considered to be a Linear Time Invariant (LTI) system, which can be completely categorized by its impulse response. What sets loudspeakers apart from other LTI-systems is the acoustical aspect including echoes, which makes it a lot harder to take accurate noise free measurements compared to other LTI-systems such as a simple RC circuit.
