  1. 1. Life Cycle Assessment of Borehole Thermal Energy Storage

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Saga Karlsson; [2022]
    Keywords : ;

    Abstract : Borehole thermal energy storage (BTES) is a technology used to store energy between seasons. It could therefore be a solution to the seasonal mismatch between the use and production of (renewable) energy, which can be used to increase energy efficiency and reduce greenhouse gas emissions.

  3. 2. Forecasting with deep temporal hierarchies : A novel way for forecasting with temporal hierarchies based on deep learning models

    University essay from Högskolan i Skövde/Institutionen för informationsteknologi

    Author : Filotas Theodosiou; [2021]
    Keywords : Forecasting; temporal hierarchies; forecast reconciliation; hierarchical forecasting; machine learning; deep learning;

    Abstract : Temporal hierarchies are being increasingly used for forecasting purposes over the past years. They have been shown to produce accurate and coherent forecasts which are beneficial for enterprises. Reconciling forecasts of different aggregation levels to achieve coherence, supports aligned decisions between different organizational levels. READ MORE

  4. 3. Pore water pressure and settlements generated from water driven DTH-drilling : - A field study

    University essay from KTH/Jord- och bergmekanik

    Author : Moa Asplind; [2017]
    Keywords : DTH drilling; hydraulic drilling; settlements; pore pressure; Venturi effect; Sänkhammarborrning; vattendriven borrning; sättningar; porvattentryck; Venturi effekten.;

    Abstract : Foundation work can cause damage to adjacent buildings and infrastructure. Drilling is performed in sensitive areas in urban projects and where the ground conditions are difficult. It is important to be aware of the installation effects from drilling. READ MORE

  5. 4. Pore pressures and settlements generated from two different pile drilling methods

    University essay from KTH/Jord- och bergmekanik

    Author : Rasmus Ahlund; Oscar Ögren; [2016]
    Keywords : DTH; bored piles; pore pressure; settlements; over-drilling; sänkhammarborrning; borrade pålar; portryck; sättningar; överborrning;

    Abstract : For piling works in sensitive soil, especially in inner city projects, it is essential to be aware of the available methods and to choose the most suitable method to minimize the risk of damaging existing buildings or endanger the workers at the construction site. Down-the-hole drilling of piles is a relatively safe method and can be separated into drilling with air powered hammers and water powered hammers. READ MORE

  6. 5. Uncovering Hidden Needs in Ground Engineering : Case Study of LKAB Wassara

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : IGOR KORDAS; [2016]
    Keywords : ;

    Abstract : Detta examensarbete utgick både från behovet av bättre förståelse för grundläggningsmarknaden av LKAB Wassara – ett innovativt företag som har utvecklat den nya tekniken av hydraulisk DTH-borrning; och från insikten att åstadkommande av kundnöjdhet genom uppfyllandet av dolda behov i byggbranschen är en lovande men samtidigt utmanande uppgift. Utmaningen som behandlas i detta examensarbete är tvåfaldig: dels leder de konventionella marknadsundersöknings metoder ofta till att de dolda kundbehoven inte erhålls, trots att dessa behov är mycket viktiga för produktinnovation; och dels är det en brist på fallstudier som utforskar de explicita eller dolda behoven i byggbranschen.
