  1. 1. Reusage classification of damaged Paper Cores using Supervised Machine Learning

    M1-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Max Elofsson; Victor Larsson; [2023]
    Nyckelord :Machine Learning; Supervised Learning; classification; 3D sensor; TriSpector1008; SICK; paper core; paper mill; KNN; Support Vector Machine; Decision Trees; Random Forest; Maskininlärning; klassificering; papperskärna; pappersbruk;

    Sammanfattning : This paper consists of a project exploring the possibility to assess paper code reusability by measuring chuck damages utilizing a 3D sensor and usingMachine Learning to classify reusage. The paper cores are part of a rolling/unrolling system at a paper mill whereas a chuck is used to slow and eventually stop the revolving paper core, which creates damages that at a certain point is too grave for reuse.

  3. 2. Single Photon LSCM in the NIR Range

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Klara Wallenbro; [2022]
    Nyckelord :LSCM; NIR; SNSPD; LSCM; NIR; SNSPD;

    Sammanfattning : In this thesis a near-infrared laser scanning confocal microscope (NIR-LSCM) is built to operate with optimal performance at 1550nm in combination with simultaneous LED light imaging at 970nm. For detection, a camera equipped with a complementary metal oxide semiconductor (CMOS) sensor and a superconducting nanowire single photon detector (SNSPD) are used for the LED part and the LSCM part, respectively.

  4. 3. Investigation of robustness of a SiC MOMS pressure sensor in high pressure/temperature operation conditions

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

    Författare :Monika Sieczka; [2022]
    Nyckelord :;

    Sammanfattning : Rigorous environmental policies and the need for higher fuel economy continuously demand new innovations in the combustion process of automotive engines. Consequently, there is an increasing necessity for active monitoring of the combustion event, and therefore, microsystems have started coming into play. LÄS MER

  5. 4. Mät och reglerproblem liners

    Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Institutionen för elektronikkonstruktion

    Författare :Björn Svensson; [2021]
    Nyckelord :Automation; industrial; process; Inpipe; liners; measurement; ultra-sound; laser; optical; sensor; regulation; feed forward.; Automation; avståndsgivare; ultraljud; optik; laser; sensor; liner; In-pipe; mätproblem; reglering; framkoppling;

    Sammanfattning : Inpipes produktion av liners sker idag till stor del manuellt. I syfte att minska variansen på produktkvalitet, råvaror och öka processens hastighet undersöktes möjligheterna att elektroniskt mäta utbuktningarna som uppstod i processen. Därefter undersöktes processens egenskaper inför att använda mätvärdena i en passande reglerstruktur. LÄS MER

  7. 5. Design of a compact wavefront sensor for measurements on the human eye

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Charlie Börjeson; [2020]
    Nyckelord :Applied physics; optical physics; visual optics; Tillämpad fysik; optisk fysik; visuell optik;

    Sammanfattning : Wavefront sensors for measurements on human eyes are usually large, expensive and difficult to move. A compact wavefront sensor would be more cost-effective and versatile as is could be used in multiple systems. The aim of this thesis was to produce a more compact and portable wavefront sensor.
