1. Realising full-scale control in wastewater treatment systems using in situ nutrient sensors
Sammanfattning : Abstract A major change in paradigm is taking place in the operation of wastewater treatment plants as automatic process control is becoming feasible. This change is due to a number of different reasons, not least the development of online nutrient sensors, which measure the key parameters in the biological nutrient removal processes, i.e. LÄS MER
2. Modelling and Lagrangian control of mixed traffic: platoon coordination, congestion dissipation and state reconstruction
Sammanfattning : Traffic congestion is a constantly growing problem, with a wide array of negative effects on the society, from wasted time and productivity to elevated air pollution and reduction of safety. The introduction of connected, autonomous vehicles enables a new, Lagrangian paradigm for sensing andcontrolling the traffic, by directly using connected vehicles inside the traffic flow, as opposed to the classical, Eulerian paradigm, which relies on stationary equipment on the road.

3. On the Robustness of Air Pollution Policy Cost-Benefit Analysis
Sammanfattning : In December 2013 the European Commission proposed an amendment of the National Emissions Ceilings Directive with new ambition levels for harmful emissions of SO2, NOx, NH3, PM2.5, and Non-Methane Volatile Organic Compounds. LÄS MER
4. A Chemometric Approach to Process Monitoring and Control - With Applications to Wastewater Treatment Operation
Sammanfattning : In this work, various aspects of multivariate monitoring and control of wastewater treatment operation are discussed. A number of important difficulties face operators and process engineers when handling online measurements from wastewater treatment processes. LÄS MER
5. Supervisory control for emission compliance of heavy-duty vehicles
Sammanfattning : Heavy freight trucks globally contribute to a significant proportion of transport-related air pollution. The dominant air pollutants from heavy freight trucks with diesel engine and exhaust aftertreatment system (EATS) are CO2, hydrocarbons (HC), CO, particulate matter (PM), NOX (NO and NO2), and NH3.
