2. 1. Realising full-scale control in wastewater treatment systems using in situ nutrient sensors

   Author : Pernille Ingildsen; Industriell elektroteknik och automation; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reglerteknik; robotteknik; Automatiska system; control engineering; Instrumentation; Wastewater treatment; Control; Full-scale plants; Control structures; Electronics and Electrical technology; Elektronik och elektroteknik; robotics; Automation; kontroll av utsläpp; pollution control; Miljöteknik; Environmental technology;

   Abstract : 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. READ MORE

4. 2. Studies in pest control for cultural property

   Author : Thomas Strang; Göteborgs universitet; []
   Keywords : HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; Pest control; cultural property collections; insect; mould; environment; integrated pest management; IPM; thermal control; pest risk to museum collections;

   Abstract : This thesis considers discrete problems of protecting cultural property from pests and examines some of the solutions. Recent decades have seen a large change in how fumigants and pesticides are used in collections of cultural property. READ MORE

5. 3. Open-Loop Optimal Control of Chromatographic Separation Processes

   Author : Anton Sellberg; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chromatography; Modelling; Optimal Control; Parameter Estimation;

   Abstract : Chromatography is an important separation process for several industries due to its ability to separate components with similar physical properties, which are difficult to separate otherwise. This method may also give high product purity, which is necessary for production of biopharmaceuticals and fine chemicals. READ MORE

6. 4. Adapting Experimental and Monitoring Methods for Continuous Processes under Feedback Control : Challenges, Examples, and Tools

   Author : Francesca Capaci; Erik Vanhatalo; Bjarne Bergquist; Murat Kulahci; Bart De Ketelaere; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Continuous process; Statistical process control; Design of experiments; Engineering process control; Quality improvement; Simulation tools; Kvalitetsteknik och logistik; Quality technology and logistics; Kvalitetsteknik; Quality Technology Management;

   Abstract : Continuous production covers a significant part of today’s industrial manufacturing. Consumer goods purchased on a frequent basis, such as food, drugs, and cosmetics, and capital goods such as iron, chemicals, oil, and ore come through continuous processes. READ MORE

7. 5. Priority setting strategies for regulatory testing of industrial chemicals

   Author : Anna Nordberg; Christina Rudén; Sven Ove Hansson; Nils Gunnar Lindquist; KTH; []
   Keywords : HUMANIORA; HUMANITIES; risk assessment; risk management; regulatory toxicology; test strategies; prioritisation; REACH; industrial chemicals; History of technology and industry; Teknik- och industrihistoria;

   Abstract : For the majority of the estimated 70,000 industrial chemical substances available on the European market today there is not enough information to enable a reasonably complete assessment of the risks that they might pose to man and the environment. Any strategy for the generation of additional data for these substances should aim at making testing as efficient as possible taking into account environmental and health protection, time, monetary cost and animal welfare.
