  1. 1. Finite Element Modeling of Installation Effects of Soil-Cement Columns

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Anne Holtmeier; [2022]
    Keywords : Deep Mixing; Soil Stabilization; Installation; Finite Element Method; PLAXIS;

    Abstract : Since the 1970's deep mixing columns have been widely used all over the world to improve the performance of soft soil in regard to bearing capacity or deformation behaviour. They are installed by mixing a binding agent, e.g. cement, in situ with the soil. READ MORE

  2. 2. Elemental variability in tree-rings as indicator for climate change : a case study on beech and oak trees at the Laacher See, Germany

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Ann-Kathrin Wild; [2022]
    Keywords : trace elements; tree-rings; dendrochemistry; dendroclimatology; ITRAX; Laacher See; mofettes; tree-bark; Quercus sp.; Fagus sp.;

    Abstract : The aim of this study was to contribute to the comprehension of the connection of element uptake in trees at the Laacher See in Germany and climatic parameters on different time scales. Understanding the relationship of certain elements in trees and temperature might enable the assignment of extraordinary high peaks in the elemental concentration, which cannot be explained by temperature, to another process as CO2 degassing of the mofettes, which are relics of the volcanic past of the lake.

  3. 3. Reinforcement and Bonded Block Modelling

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Georgios Aristeidis Skarvelas; [2021]
    Keywords : Bonded Block Modelling; 3DEC; Tunneling; Reinforcement; Distinct Element Method; Numerical Modelling;

    Abstract : The objective of this master’s thesis is to evaluate the use of Bonded Block Modelling (BBM) in 3DEC software combined with hybrid rock bolts, for three different cases. These cases included the laboratory rock bolt case, the shearing case and the blocky rock mass case. READ MORE

  4. 4. Cross-comparison of Non-Linear Seismic Assessment Methods for Unreinforced Masonry Structures in Groningen

    University essay from KTH/Betongbyggnad

    Author : Viktor Peterson; Zihao Wang; [2020]
    Keywords : Non-linear time-history analysis; non-linear pushover analysis; N2- method; equivalent frame model; continuum model; numerical seismic assessment; unreinforced masonry buildings iv;

    Abstract : A large amount of low-rise unreinforced masonry structures (URM) can be foundin Groningen, the Netherlands. More and more induced earthquakes with shortduration have been detected in this region due to gas exploitation. READ MORE

  5. 5. Analysis of stellar spectra with machine learning

    University essay from Lunds universitet/Institutionen för teoretisk fysik; Lunds universitet/Astronomi; Lunds universitet/Institutionen för astronomi och teoretisk fysik

    Author : Alvaro Segovia Otero; [2020]
    Keywords : Galactic Archaeology; machine learning; chemical abundances; FGK stars; Physics and Astronomy;

    Abstract : Researchers in the field of Galactic Archaeology have entered the era of industrial revolution. Upcoming surveys are planning on observing tens of millions of stars and high precision and accuracy must be ensured when deriving their stellar parameters and elemental abundances. READ MORE
