    Abstract : Organic solar cells (OSCs) based on non-fullerene acceptors (NFAs) have attracted a great deal of attention in recent years due to their rapidly increasing efficiency and enormous potential. In this work, the optical and electronic properties of systems containing the very promising non-fullerene acceptor PYT have been thoroughly studied with the use of the density functional theory (DFT) and the time-dependent density functional theory (TDDFT).

    Abstract : In this thesis, an optimization based steering methods based on differential flatness and quadratic programming has been investigated. The method has been implemented into an RRT*-planner and tested in simulation. READ MORE

  4. 3. Design and function of CVC rolls as a flatness actuator in a cold rolling mill

    University essay from KTH/Materialvetenskap

    Author : Jonas Johannesson; [2012]
    Keywords : Flatness; actuators; CVC; cluster mill; Cold rolling; strip; Planhet; ställdon; CVC; mångvalsarsverk; kallvalsning; band;

    Abstract : When cold rolling thin steel strips with high tensile strength, reversible cluster mills are used. The customer’s demands are high on the products flatness, which is controlled by the different flatness actuators that the mill is equipped with. READ MORE

  5. 4. Flatness calculation of metal stream

    University essay from Institutionen för teknik och naturvetenskap; Tekniska högskolan

    Author : Adnan Glibo; [2007]
    Keywords : ;

    Abstract : This thesis project comprises a review of documentation/programmer code, and the creation of the algorithm for calculation of the flatness. The old program "PLANHETSMÄTNING 839:2" is written in DOS. The algorithm has now been applied in LabVIEW and the performance has been compared with the old program. READ MORE
