1. 1. Effectiveness of Barrier Well by Pumping Ratio Control for Saltwater Intrusion: Lab-Scale Experiments and Numerical Modeling

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : Shinichi Ozaki; [2021]
   Keywords : Saltwater intrusion; Barrier well; Pumping ratio control; Production well; salinity-affected coastal aquifer; Critical groundwater pumping ratio; Technology and Engineering;

   Abstract : Saltwater intrusion is the most challenging problem in coastal regions. To prevent saltwater intrusion, saltwater pumping from a barrier well is widely applied, which is a direct abstraction of intruded saltwater from a coastal aquifer. Owing to its easy installation, many studies have been carried out. READ MORE

3. 2. On optimal control of the wastegate in a turbocharged SI engine

   University essay from KTH/Reglerteknik

   Author : Roberto Argolini; Viviana Bloisi; [2007]
   Keywords : ;

   Abstract : The project aims to improve positive torque transient response through more advanced wastegate controllers than what are used today. All controllers are developed for a standard General Motors turbocharged engine. In many turbocharged SI engines, a wastegate is used for preventing the turbine to overrun and to decrease the pumping loss. READ MORE

4. 3. Optimal control of a diesel engine with EGR and VGT

   University essay from Institutionen för systemteknik

   Author : Markus Welander; Jonas Olsson; [2006]
   Keywords : TOMOC; Matlab; PID controller; fmincon;

   Abstract : To fulfill todays requirements on emissions from engines, SCANIA has developed an engine with EGR (Exhaust Gas Recirculation) and VGT (Variable Geometry Turbine). This gives two extra control signals to take into consideration. READ MORE
