  1. 1. Approximating Damping Coefficient of Bolted Joints using the Finite Element Method

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Abhiroop Chatterjee; [2023]
    Nyckelord :;

    Sammanfattning : Bolted joints are important due to their energy dissipation property in structures,but the damping mechanism is also highly nonlinear and localized. The goal ofthis thesis is to develop an accurate method for modeling bolted joint dampingin large structures using finite element (FE) software. LÄS MER

  3. 2. Modeling and Simulation of a Remote Controlled Weapon Station

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Mats Svalstedt; [2022]
    Nyckelord :Modeling; System identification; Nonlinear black-box; Remote controlled weapon station; Modellering; Systemidentifiering; Icke-linjär black-box; Fjärrmanövrerad vapenstation;

    Sammanfattning : Understanding how a system behaves when exposed to different scenarios is key when improvingand developing complex structures. The amount of different approaches is immense and variesfrom case to case. LÄS MER

  4. 3. Toward Adaptation of Data Enabled Predictive Control for Nonlinear Systems

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Hashem Ghasemi; [2022]
    Nyckelord :DeePC; Data Driven Control; Nonlinear System; Non-holonomic Ground Robot; Double Integrator Model; Inverted Pendulum.; DeePC; Datadriven Kontroll; Icke-linjärt System; Icke-holonomisk Markrobot; Dubbelintegratormodell; Inverterad Pendel;

    Sammanfattning : With the development of technology and availability of data, it is sometimes easier to learn the control policies directly from the data, rather than modeling a plant and designing a controller. Modeling a plant is not always possible due to the complexity of the plant. LÄS MER

  5. 4. Applying Nonlinear Mixed-Effects Modeling to Model Patient Flow in the Emergency Department : Evaluation of the Impact of Patient Characteristics on Emergency Department Logistics

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Umberto Rosamilia; [2022]
    Nyckelord :Emergency Department; Nonlinear Mixed-Effects Modeling; Healthcare Logistics; Patient Flow Modeling; Patient Pathways; Markov Process; Akutmottagning; Icke-Linjär Blandad Effektmodellering; Vårdlogistik; Patientflödesmodellering; Patientflöde; Markovprocess;

    Sammanfattning : Emergency departments are fundamental for providing high-quality care, and their operations directly impact the logistics of the hospitals in their entirety. Poor emergency department performance leads to delays, prolonged hospitalization, and improper allocation of resources, reducing the quality of the provided care and increasing costs. LÄS MER

  7. 5. Multibody modelling of the vibrations in an aircraft engine

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Charly Mollet; [2022]
    Nyckelord :Vibrations; Multibody Modelling; Rolling Bearings; Rotor Dynamics; Reduction Processes; Vibrationer; multikroppsmodellering; rullingslager; rotordynamik; reducktionsprocesser;

    Sammanfattning : During the assembly of aircraft engines, some clearance is left in the rolling bearings mainly to reduce friction. However this clearance might allow the rolling element to vibrate during flight. Indeed, unwanted vibrations called non-synchronous vibrations (NSV) appear on the data recorded by the sensors on some development engines. LÄS MER
