1. Hydrogen in nano-sized metals : Diffusion and hysteresis effects
Sammanfattning : Metal hydrides can be used as hydrogen storage materials for fuel cells and batteries, and as sensors for detecting hydrogen gas. The use of metal hydrides for hydrogen storage can be hindered by poor kinetics and low capacity. Moreover, poor sensitivity, long recovery and response time, limit the applications of metal hydrides as hydrogen sensors. LÄS MER
2. Hysteresis Modelling of High Temperature Superconductors
Sammanfattning : .... LÄS MER
3. Estimation of torque in heavy duty vehicles with focus on sensor hysteresis
Sammanfattning : For diagnosis and feedback control of vehicle powertrains, it is highly desired to monitor the torques at different locations online. The most obvious way to do this is to measure cylinder pressures, from which cylinder individual delivered torques can be calculated, or to use torque sensors. LÄS MER
4. A lumped element transformer model including core losses and winding impedances
Sammanfattning : In order to design a power transformer it is important to understand its internal electromagnetic behaviour. That can be obtained by measurements on physical transformers, analytical expressions and computer simulations. LÄS MER
5. Electromagnetic transformer modelling including the ferromagnetic core
Sammanfattning : In order to design a power transformer it is important to understand its internal electromagnetic behaviour. That can be obtained by measurements on physical transformers, analytical expressions and computer simulations. LÄS MER
