  1. 1. Joint CFR and DPD optimization for 5G Digital Front Ends

    University essay from Lunds universitet/Matematik LTH

    Author : Gustav Olsson; [2023]
    Keywords : Crest Factor Reduction; Digital Pre-Distortion; Power Amplifier; Parameter Optimization; 5G; Base Station; Memory Polynomial; Technology and Engineering;

    Abstract : This thesis project investigates the topic of joint optimization for crest factor reduction and digital predistortion blocks, which are used for digital correction of analogue impairments in digital radio front ends. The work first investigates the effects of joint parameter variation of the above blocks on the global performance and computational cost of the digital chain, given reference CFR and DPD algorithms.

  3. 2. Numerical analysis of a bearing strength in delaminated composite joint

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Olavi Kukkonen; [2023]
    Keywords : Bearing strength; Single-lap shear; Delamination; Countersinking; Hole size;

    Abstract : Composite structures are commonly joined using adhesive or mechanical joints, withmechanical joints being preferred when components need to be removable for maintenancepurposes. However, the presence of mechanical joints introduces a discontinuity in theload path, which can serve as an initiation point for failure and needs to be taken intoaccount in the design of the joint.

  4. 3. Modeling of a ball contact with a coated plate

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Mohammadreza Saeedi; [2023]
    Keywords : Pin on disc tribometer; coating; contact mechanics; finite element method; tribology; Pin on disc tribometer; beläggning; kontaktmekanik; finita elementmetod; tribologi;

    Abstract : During tightening of a screw, the variation in friction will affect the force acting on the joint, especially when tightening using torque as a control parameter. So, it is crucial to have a proper understanding of the contact mechanism and friction in the screw head to joint and thread interfaces. READ MORE

  5. 4. Adhesive bonding of fiber laminate patch to sandwich-structured composite

    University essay from Lunds universitet/Materialteknik

    Author : Daniel Nesic; [2022]
    Keywords : Adhesive bonding; Shipbuilding; Composite construction; Finite element method in structural mechanics; Fiber reinforced plastics; Optical microscopy analysis; Fractography; Technology and Engineering;

    Abstract : By using composites when constructing vehicles, lighter weight and thus better performance can be achieved. Composites are widely used in airplanes and small boats, but has yet to be incorporated in larger ships such as freighters and cruise ships. The main hindrance for its use is the lack of practical knowledge and experience. READ MORE
