  1. 1. EV battery temperature estimation : Designing a model for minimal temperature of high-voltage battery in a BEV

    University essay from Mittuniversitetet/Institutionen för data- och elektroteknik (2023-)

    Author : Björn Arvidsson; [2023]
    Keywords : BEV; temperature estimation; lowpass filter; BEV; lågpassfilter; temperaturestimering;

    Abstract : Fordonsindustrin är inne i ett skifte, där förbränningsmotorer (ICE) bör-jar fasas ut och det satsas mer på eldrift med hjälp av batterier (BEV).  I detta arbete, som efterfrågades av Volvo Cars, utvecklades en matema-tisk modell som uppskattar den lägsta temperaturen i en elbils högspän-ningsbatteri.

  3. 2. Exercise Classification with Machine Learning

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Joel Ekstrand; [2023]
    Keywords : Machine learning; signal processing; noise reduction; feature extraction; exercise classification; machine learning; signalprocessering; brusreducering; feature extraction; rörelseklassificering;

    Abstract : Innowearable AB has developed a product called Inno-XTM that calculates musclefatigue during three exercises: squat jumps, wall sit, and leg extension. Inno-X uses an accelerometer and a surface electromyography sensor. READ MORE

  4. 3. Temperature Based Estimation of the Time-Resolved Massflux of ICE Exhaust Gas Flow

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

    Author : Mayur Khedekar; [2021]
    Keywords : ICE exhaust flow condition; Thermocouples; Resistance wire thermometers; Nu correlations; ICE exhaust Mass-fluxstudy; Heat transfer coefficient; Heat balance equation for thermocouple; Constant current anemometry; ICE-avgasflödesförhållande; Termoelement; Motståndstrådstermometrar; Nu-korrelationer; ICE-avgas Massflödesstudie; Värmeöverföringskoefficient; Värmebalansekvation för termoelement; Konstant strömanemometri;

    Abstract : The aim ofthe study was to provideinformation and experience gained with fine wire thermocouples (TCs)or resistance wire thermometers (RWTs) temperature signals to estimate the timeresolved heat transfercoefficient. Constant current method was assumed in the study and medium used in this study was air. READ MORE

  5. 4. Extended and Unscented Kalman Filtering for Estimating Friction and Clamping Force in Threaded Fasteners

    University essay from Uppsala universitet/Signaler och system

    Author : Mohammad Al-Barghouthi; [2021]
    Keywords : Estimation Theory; Extended Kalman Filter; EKF; Unscented Kalman Filter; UKF; Observability; Friction; Clamping Force; Tightening; Torque Controlled; Bolt; Threaded Fasteners;

    Abstract : Threaded fasteners tend to break and loosen when exposed to cyclic loads or potent temperature variations. Additionally, if the joint is held tightly to the structure, distortion will occur under thermal expansion issues. READ MORE

  6. 5. Development of an underwaterruler using an AUV-deployedbeacon and Matched filter CFARdetector

    University essay from KTH/Marina system

    Author : Yaolin Ge; [2020]
    Keywords : ;

    Abstract : Our ocean covers more than 70% of our planet’s surface. It is a huge reservoir continuously supplying us with enormousvaluable resources. The autonomous aquaculture, deep sea mining, subsea oil / gas exploitation and marine biology etc.,are the increasingly important driving forces for the development of underwater robotics. READ MORE
