  1. 1. Quality Control in Aluminium Profiles : Non-destructive Methods using Non-linear Ultrasonic

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Viktor Svensson; Robin Raymundsson; [2023]
    Nyckelord :Acoustic; defect; detection; harmonic; Akustisk; defekt; detektion; överton;

    Sammanfattning : When aluminium profiles are manufactured, defects may arise, especially when theprofiles are manufactured through extrusion. During the extrusion process, thesedefects occur on parts of the extruded material because of contaminates that needto be found. LÄS MER

  3. 2. III-V semiconductor waveguides for application in nonlinear optics.

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Andreas Charalampous; [2022]
    Nyckelord :InGaP; optical waveguides; integrated optics; quantum nonlinear optics; SHG; SPDC; InGaP; optiska vågledare; integrerad optik; icke-linjär kvantoptik; SHG; SPDC;

    Sammanfattning : This thesis presents studies on III-V semiconductor waveguides with particular emphasis on second-order optical nonlinearity. The nonlinear processes that were investigated in this thesis are the Second Harmonic Generation (SHG) and the Spontaneous Parametric Down-Conversion (SPDC). LÄS MER

  4. 3. 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

  5. 4. Micromagnetic study of spin Hall nano-oscillator arrays and their synchronization dynamics

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

    Författare :Ari Sigurdsson; [2020]
    Nyckelord :spintronics; spin Hall nano-oscillators; spin wave; synchronization; micromagnetic modelling.; spinntronik; spinn-Hall nano-oscillatorer; spinn wave; synkronisering; mikromagnetisk modellering.;

    Sammanfattning : Spintronics is the study of electron spins and their utilization in electronic devices. Within this field, spin-based oscillators have shown promise for mi- crowave signal generation as they can operate at high frequencies, are small in scale and are compatible with modern fabrication techniques.

  7. 5. Iterative Learning Control for Preparative Chromatography

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Daniel Espinoza; [2020]
    Nyckelord :Chemical Engineering; Kemiteknik; Chromatography; Automatic Process Control; Iterative Learning Control; ILC; Simulation; Protein Purification; Python; Ion-Exchange; Automation; Batch Processing; Downstream Processing; Technology and Engineering;

    Sammanfattning : There is a desire for a fully automated downstream process in pharmaceutical protein production. One part of the downstreaming process is preparative chromatography. A good separation between the product and other proteins, as well as good productivity, are desired. LÄS MER
