4. 8. Electric Vehicle Charging Stations In India (The challenges and barriers being faced by charge point operators and a look at possible solutions)

   University essay from Lunds universitet/Ekonomisk-historiska institutionen

   Author : Mirza Nooruddin Ahmad; [2020]
   Keywords : Business and Economics;

   Abstract : The Paris agreement was the first time all 196 member states agreed to find solutions to fight global warming and keep temperatures 2 degree Celsius. Under the umbrella of the agreement, the Paris Declaration on Electro-Mobility and Climate Change called for action towards electric mobility. READ MORE

5. 9. Calibration and Validation of Efficient Combustion and EmissionModels for 3D-CFD EngineSimulations

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Vikas Shettihalli Anandreddy; [2019]
   Keywords : ;

   Abstract : To accurately analyze combustion and emissions in the internal combustion engine, hundreds of chemical species have to be transported in the computational domain in the form of a detailed chemical mechanism. The use of this detailed chemical mechanism in the computational domain leads to an increase in computational time. READ MORE

6. 10. Investigating Optical-Field-Induced Currents in GaN using Ultrafast Lasers

   University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Author : Vidar Flodgren; [2019]
   Keywords : GaN; gallium nitride; nanoscience; material science; ultrafast lasers; Yb Laser; Pharos Laser; titanium sapphire laser; device fabrication; lift-off; gold etching; optical-field-induced currents; modelling; matlab; Physics and Astronomy;

   Abstract : This study saw the development of an experimental setup capable of generating and measuring optical-field-induced currents in a variety of nanodevices fabricated specifically for this project. Each device design features two metallic contacts, closely separated by about 5 micrometers, deposited onto a semiconductor or insulator substrate. READ MORE
