2. 1. Towards Active Car Body Suspension in Railway Vehicles

   Author : Jessica Fagerlund; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Decoupling; Model reduction; Active suspension; MIMO systems; LQ control;

   Abstract : Today, most railway suspension systems are passive. The most wide-spread exception isactive car body tilt systems, which are mounted in some high-speed trains. Replacingsome of the passive suspension components with active could reduce the weight and costof the vehicle. READ MORE

4. 2. On Objective Measures for Ride Comfort Evaluation

   Author : Katrin Strandemar; Håkan Hjalmarsson; Staffan Nordmark; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ride; Objective evaluation; Vehicle dynamics; Automatic control; Reglerteknik;

   Abstract : An essential tool in the truck development process is the ability to quantify and grade vehicle dynamic behavior. Today this is performed either through subjective or objective tests. Subjective tests have the disadvantage that numerous factors influence test drivers’ opinions while objective measures have the advantage of repeatability. READ MORE

5. 3. Analytical Quality by Design Method Development for Vaccine Characterization

   Author : Lars Geurink; Catharina Sänger van de Griend; Mikael Hedeland; Martijn Schenning; Iulia Oita; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; viral vaccines; adenovirus; influenza; polio; COVID; corona; capillary electrophoresis; analytical quality by design; analytical method development; CGE; icIEF; CZE; crude cell suspension analysis; in-process sample analysis; quality control testing; biopharmaceutical characterization; Analytisk farmaceutisk kemi; Analytical Pharmaceutical Chemistry;

   Abstract : Vaccines that are safe, efficacious, and can be rapidly developed are needed to prevent and to react to emerging global infectious disease threats such as influenza, Polio, and Coronavirus diseases. Fast and reliable analytical methods are required without delay to support vaccine process and product development, characterization, and quality control testing. READ MORE

6. 4. Active Lateral Secondary Suspension in a High-Speed Train to Improve Ride Comfort

   Author : Anneli Orvnäs; Sebastian Stichel; Viktor Berbyuk; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railway; active suspension; ride comfort; sky-hook; Hinf; multi-body simulations; on-track tests; Vehicle engineering; Farkostteknik;

   Abstract : Active secondary suspension in trains has been studied for a number of years, showing promising improvements in ride comfort. However, due to relatively high implementation and maintenance costs, active technology is not being used in service operation to a large extent. READ MORE

7. 5. Conservation Laws, Numerical Schemes and Control Strategies for Sedimentation and Wastewater Treatment

   Author : Sebastian Farås; Matematik LTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Conservation law; Temple class system; numerical scheme; continuous sedimentation;

   Abstract : A consistent theme throughout this thesis is quasilinear partial differential equations (PDEs) appearing in one-dimensional models of sedimentation for solid-liquid separation of suspensions. We mainly focus on continuous sedimentation in so-called clarifier-thickeners (CTs), which are found in mineral processing and wastewater treatment. READ MORE
