1. 1. A deep learning approach for drilling tool condition monitoring in Raiseboring

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Hedaya Alyousif; [2023]
   Keywords : drilling tool condition; deep learning; drilling signals; CNN; spectrogram; Raisboring;

   Abstract : Drilling tool wear can significantly affect the performance of the drilling operation and add extra cost to it. Accurate detection of drilling tool condition is very important for enabling proactive maintenance, minimizing downtime, and optimizing drilling processes. READ MORE

3. 2. Chip Management in Milling and Drilling of Ductile Cast Iron

   University essay from Lunds universitet/Industriell Produktion

   Author : Alexander Jönsson; Giacomo Aliboni; [2023]
   Keywords : Chip Carryover; Chip Management; Ductile Cast Iron; Chip Removal; Chip Asportation; Milling; Drilling; Technology and Engineering;

   Abstract : This paper presents a comprehensive cross-functional analysis of machining operations for ductile cast iron components in the automotive industry, focusing on the problem of chip carryover and its impact on downstream processes. The research aims to understand the role of machining and identify the source of the issue, by analyzing different machining sequences and the chips that affect the final product or subsequent production stages.

5. 4. 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.

6. 5. A comparison of 2D and 3D resistivity surveys for 3D inversion imaging

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Julia Cavell; [2022]
   Keywords : ;

   Abstract : Following study focuses on electrical resistivity surveying and how it can be used as an exploration method to increase knowledge of subsurface structures. Future scenarios with increasing population and rapid urbani-zation, put high demands on reliable infrastructure; safe foundations, un-derground structures, environmental safety and access to resources.
