  1. 1. Implementering av Skogliga Grunddata i hprGallring vid andragallring

    Kandidat-uppsats, SLU/School for Forest Management

    Författare :Felix Nilsson; Joakim Bengtsdahl; [2023]
    Nyckelord :gallring; uppföljning; laserskanning;

    Sammanfattning : Gallring är en av de skogsvårdsåtgärder som utförs i våra skogar för att bemöta de olika skogliga mål som skogsägarna har för sin skog. I Sveriges skogar så utförs gallringsåtgärder på ca 400 000 hektar årligen. LÄS MER

  2. 2. Design of a Bistable Origami Stent with Pneumatic Actuation

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Michelle von Rosen; [2023]
    Nyckelord :;

    Sammanfattning : What if stents could be easier removed when complications arise or removed once theirjob has been done? No matter how perfect a stent design becomes, the fundamental issueis that a foreign object in the body under extended periods eventually will cause devicedegradation and complications. So instead of making a long-term solution of a perfectstent, the focus in this paper is redirected from expensive materials to a simple design,with simple materials. LÄS MER

  3. 3. Development of an Investigation Method to Analyse Effect of Laser Cutting on Iron Losses in an Electric Machine

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

    Författare :Rishabh Raj; [2022]
    Nyckelord :Electrical machine; iron losses; laser cutting; loss models; manufacturing defects; single sheet tester; Elektrisk maskin; järnförluster; laserskärning; förlustmodeller; tillverkningsfel; enplåtsprovare;

    Sammanfattning : In this fast pace world, climate change is one of the primary concerns worldwide. The world is racing towards reducing CO2 emissions by focusing on decreasing energy consumption. Electric motors capture about two-third of the industrial energy consumption, of which the most growing sector is electrical vehicles. LÄS MER

  4. 4. Digitalisering av avrapportering i produktion vid BAE Systems AB

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Robert Svensson; [2022]
    Nyckelord :Digital transformation; production monitoring; Lean;

    Sammanfattning : BAE Systems Hägglunds in Ornsköldsvik is an engineering company that producesoff-road and combat vehicles for military and civilian purposes and sees a need fordigital transformation and streamlining of production in order to maintain contractualdelivery times and be an employer of the future. The purpose of this thesis was to investigate a way to facilitate and streamline theorder card handling of a laser machine at the manufacturing site in Örnsköldsvik,where the reporting of orders is expected to become a bottleneck in production.

  5. 5. Measuring the Pulse Duration and the Time-Dependent Polarisation State of Ultrashort Laser Pulses with the D-Scan Technique

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

    Författare :Daniel Díaz Rivas; [2022]
    Nyckelord :pulse characterisation; ultrashort; laser; femtosecond; dispersion scan; polarisation; wave plate; temporal reconstruction; electric field reconstruction; time-dependent polarisation; polarisation gate; Physics and Astronomy;

    Sammanfattning : Ultrashort laser pulses with time-dependent polarisation states have many applications, such as the generation of isolated attosecond pulses and the study of the optical chirality of molecules. In this project the polarisation gate, built from two quarter-wave plates of different orders, is thoroughly characterised in experiment and simulation. LÄS MER
