1. 1. Staff Shortage on SJ Trains

   Kandidat-uppsats, KTH/Matematisk statistik

   Författare :Casper Öberg; Nora Moro; [2023]
   Nyckelord :Multiple linear regression; Residual analysis; Multicollinearity; Staff shortage; Forecast; Trains; Multipel linjär regression; Residualanalys; Multikollinearitet; Personalbrist; Prognos; Tåg;

   Sammanfattning : This thesis is a case study in collaboration with SJ AB, a government owned railway companyin Sweden. The employees aboard the trains are an essential part of operating thetrains efficiently. Therefore, it is vital to forecast absences well in order to avoid havingto cancel train trips or having employees work over time. LÄS MER

3. 2. THIRD HAND : A solution for the fuel tank assembly at Scania Södertälje

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

   Författare :SandraMarie Westerberg; Tova Ödesjö; [2023]
   Nyckelord :Industrial Design Engineering; Ergonomics; Human-centered design; User-centered design; Safety; Third hand; Automotive; Production; Teknisk Design; Ergonomi; Människocentrerad design; Användarcentrerad design; Säkerhet; Tredje handen; Fordons industri; Produktion;

   Sammanfattning : Scania recently introduced a new fuel tank design. This new design arose a need for extra help when mounting the tank in production, which was solved with two little hooks on each tank. These hooks are today known as the current third hand solution. LÄS MER

5. 4. Analogue Circuit for Detection of Ageing Phenomena in Electric Drives

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Yudong Lin; [2023]
   Nyckelord :Electric Drives; Ageing Process; Pulse-Width Modulation; Ringing Current; Peak Holder; Analogue Circuits; Elektriska drivsystem; Åldringsprocess; Pulsbreddsmodulering; Ringningar i strömmen; Toppvärdesdetektor; Analog krets;

   Sammanfattning : This master thesis presents an analogue peak holder circuit design aimed at facilitating the non-invasive inspection of the ageing process in electric drives. The ageing process of electric drives is a crucial aspect that demands accurate monitoring to ensure their long-term performance and reliability. LÄS MER

7. 5. Deep Neural Networks as SurrogateModels for Fuel Performance Codes

   Kandidat-uppsats, Uppsala universitet/Tillämpad kärnfysik

   Författare :Wenhan Zhou; [2023]
   Nyckelord :Transuranus; AI; Nuclear Fuel Rods;

   Sammanfattning : The core component of a nuclear power plant is the reactor and the fuel rods that supply it with fission fuel. Efficient and safe energy extraction is thus highly dependent on the reactor design and the conditions of the fuel rods. To anticipate high-quality operation and potential risks in advance, one must perform simulations on the fuel rods. LÄS MER
