  1. 11. PCBA verification and fault detection using a low-frequency GMR-based near-field probe with magnetic closed-loop feedback compensation : A non-contact alternative to physical probing

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Joacim Sundh; [2022]
    Keywords : GMR; sensor; magnetic field; near-field; probe; linearity; PCB; coil; PCBA; analogue integrated circuits; analog; operational amplifiers; electrical fault detection; feedback circuits; in-circuit tests; GMR; sensor; magnetfält; närfält; sond; linjäritet; mönsterkort; spole; kretskort; analoga integrerade kretsar; operationsförstärkare; elektrisk feldetektering; återkopplingskretsar; kretskortstest;

    Abstract : As electronics are getting both smaller and more advanced, the need to verify and validate remains and the means are getting more complex the more functions and components are added. Traditionally, in-circuit tests (ICTs) are performed by probing dedicated test points on the Printed Circuit Board Assembly (PCBA) in a test sequence that is unique to each product. READ MORE

  3. 12. Validation of promoter and enhancer interactions of a putative cancer gene in Triple Negative breast cancer lines

    University essay from KTH/Proteinvetenskap

    Author : Keerthi Anand Raghavender Anand; [2022]
    Keywords : Triple Negative Breast Cancer cells; Prenylation; Hi-C; HiCap; enhancer-promoter interactions; Trippelnegativa bröstcancerceller; Prenylering; Hi-C; HiCap; interaktioner med förstärkare-promotor;

    Abstract : Trippelnegativ bröstcancer (TNBC) är den mest maligna formen av bröstcancer utan någon framträdande behandlingsbar biomarkör. Således har den djupa återfallsfrekvensen och bristen på behandlingsalternativ öppnat behovet av att förstå TNBC: s etiopatogenes och molekylära mekanism. READ MORE

  4. 13. Design of a Custom Amplifier for an Ultrasound Cell Platform

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Majd Kasem Alchar; Yasmin Al-Kazaz; [2022]
    Keywords : Amplifier; PCB; LTSpice; KiCAD; EDA; ECAD.; Förstärkare; Kretskort; LTSpice; KiCAD; EDA; ECAD;

    Abstract : In cancer research, studies on cells are often done in 2D, grown on plates which are not realistic. Therefore, a specialized system is being designed to build 3D cell structures. This system requires a fitting amplifier that is of low cost and changeable gain. READ MORE

  5. 14. Nonlinear mode coupling and parametric amplification with superconducting kinetic inductance

    University essay from KTH/Tillämpad fysik

    Author : Daniele Lopriore; [2022]
    Keywords : Quantum technology; microwave engineering; nanofabrication; parametric amplifiers; multimode entanglement; kinetic inductance; Kvantteknologi; mikrovågsteknik; nanotillverkning; parametriska förstärkare; multimodentrassling; kinetisk induktans;

    Abstract : We investigate the resonant characteristics of superconducting meandering nanowires to design a nonlinear kinetic inductance traveling-wave parametric amplifier. The devices are patterned out of 15 nm thick NbTiN films. They consist of a coplanar waveguide, that shrinks into 100 nm wide meandering nanowires. READ MORE

  6. 15. "Resonance frequency, Q-factor, coupling of a cylindrical cavity and the effect on graphite from an alternating electric field".

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Jakob Gölén; Simon Persson; [2021]
    Keywords : Q-factor; Resonance frequency; Cavity; Microwaves; Heating; Q-faktor; Resonansfrekvens; Kavitet; Mikrovågor; Uppvärmning;

    Abstract : The purpose of this project was to investigate a cylindrical cavity resonator and use microwaves to heat up a material in the cavity. This was done by measuring the Q-factor and the resonance frequency of the cavity, both with and without material inside. READ MORE
