2. 1. Hydraulic Power Steering System Design in Road Vehicles : Analysis, Testing and Enhanced Functionality

   Author : Marcus Rösth; Jan-Ove Palmberg; Nick Vaughan; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydraulic Power Steering; Active Safety; Comfort function; Shuttering; Linear modelling; Fluid mechanics; Strömningsmekanik;

   Abstract : Demands for including more functions such as haptic guiding in power steering systems in road vehicles have increased with requirements on new active safety and comfort systems. Active safety systems, which have been proven to have a positive effect on overall vehicle safety, refer to systems that give the driver assistance in more and less critical situations to avoid accidents.

4. 2. Mitigating Knock in Heavy Duty Spark Ignition Engines : Experiments and simulations of diluted ethanol and methanol combustion

   Author : Senthil Krishnan Mahendar; Anders Christiansen Erlandsson; Christer Spiegelberg; James Szybist; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ethanol; Methanol; Dilution; Spark Ignition; Miller Timing; Machine Design; Maskinkonstruktion;

   Abstract : To effectively reduce fossil fuel dependence in the transport sector, an unprecedented increase in renewable fuel production is required. Short chain alcohols, such as ethanol and methanol, are well placed as they can be produced in a variety of renewable pathways from most carbon sources. READ MORE

5. 3. HCCI Operation - Closed loop combustion control using VVA or dual fuel

   Abstract : The current technology within combustion engines have the possibility of handling the more stringent legislative demands on combustion engines. However the required solutions are getting more expensive and technically challenging. READ MORE

6. 4. Development of Micro Liquid Separation Techniques using Electrospray Ionisation Mass Spectrometry in the Analysis of Polar Compounds and Proteins/Peptides

   Author : Jenny Samskog; Elsa Lundanes; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Analytisk kemi; Analytical chemistry; Analytisk kemi; Analytical Chemistry; Analytisk kemi;

   Abstract : Electrospray ionisation (ESI) coupled to mass spectrometry (MS) is one of the most important detection techniques for chemical analysis of small drugs as well as large biomolecules in life science today. In this thesis, aspects on improved compatibility between liquid based separation systems and mass spectrometric detection were investigated regarding buffers, sample preparation and analysis of polar compounds as well as peptides and protein digests for enhanced ESI-MS performance.
