1. 21. Design and test of a robotic cell for stud bolt welding in heat exchangers for SWEP International AB

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Amparo Tarazona Ferrandis; [2021]
   Keywords : Technology and Engineering;

   Abstract : This project targeted automating production steps where stud bolts are welded on a heat exchanger within allowed perpendicularity and position requirements. Until now, this has been a manual process where an operator uses steel templates to position the bolts in the right place and manual welding guns to weld the bolts. READ MORE

3. 22. Euthanizing single or pairs of sick, injured or weak piglets with nitrogen foam : effects on animal welfare

   University essay from SLU/Dept. of Animal Environment and Health

   Author : Emma Nilsson; [2021]
   Keywords : Euthanasia; animal welfare; anoxia; controlled atmosphere; nitrogen; behaviour;

   Abstract : In pig production, it is inevitable having to euthanize some piglets due to sickness, injuries or weakness. The methods available for euthanizing piglets that are 0-42 days are blunt force trauma and captive bolt followed by sticking. READ MORE

4. 23. Design and validation of the control systemfor a Pin-on-Disc Machine

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : SIMON CALMINDER; JONAS XU; [2021]
   Keywords : Pin-on-Disc; Tribometer; Model; PID; Control; Pinne-skiva; Tribometer; Modell; PID; Reglersystem;

   Abstract : The friction between the under-head of a bolt and the mounting surface affects the necessary torque from a tightening tool. To study the friction behaviour during a highly dynamic tightening process, a Pin-on-Disc testrig has been developed. READ MORE

5. 24. Real-time Classification of Multi-sensor Signals with Subtle Disturbances Using Machine Learning : A threaded fastening assembly case study

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

   Author : Theodor Olsson; [2021]
   Keywords : Multivariate time series classification; Residual-based fault detection; Low-pass filter; Support vector machine; Threaded fastening assembly; Multivariat tidserieklassificering; Residual-baserad feldetektering; Lågpass-filter; Stödvektormaskin; Åtdragningsmontering;

   Abstract : Sensor fault detection is an actively researched area and there are a plethora of studies on sensor fault detection in various applications such as nuclear power plants, wireless sensor networks, weather stations and nuclear fusion. However, there does not seem to be any study focusing on detecting sensor faults in the threaded fastening assembly application. READ MORE
