  1. 1. Jämförelse av uppskattat terrängtransportavstånd mellan beslutstödet Timbertrail och Stora Enso Skogs bortsättningshandbok

    University essay from SLU/School for Forest Management

    Author : Emil Arkegrim; Andreas Appelbring; [2023]
    Keywords : skotning; prissättning; planering; basstråk; basväg;

    Abstract : De tio senaste åren har det i Sverige nettoavverkats mellan 84–92 miljoner m³sk per år och vanligt är att avverkningen planeras, samt beräkning av terrängtransportavståndet. Under dessa tio år har det även utvecklats flera olika beslutstöd för att effektivisera, standardisera och förbättra processen att planera basstråk och basvägar samt att beräkna terrängtransportavståndet.

  3. 2. Numerical calculations ofgradients using random walkmethodswith applications to electriccurrents

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Oscar Broliden; [2023]
    Keywords : ;

    Abstract : We have studied examples of random walk methods (RWM) applied to electric problems, solving the Laplace equation. Especially we did calculationswith digital pictures as domains, and evaluated an improvement in calculation speed for the random walk method. READ MORE

  4. 3. Validation of a method utilising MR images for dose planning of prostate cancer treatment : Validation of new coil technology applied on the pelvis region of healthy volunteers

    University essay from Linköpings universitet/Institutionen för hälsa, medicin och vård

    Author : Tova Rung; [2022]
    Keywords : Synthetic CT; Air coil;

    Abstract : By generating a synthetic CT image (sCT) directly from the MRI, the electron density can be calculated, and the CT examination can be excluded from the patient flow minimizing the risk of uncertainties in the registration. Basing the radiation treatment process solely on MR images is called MRI-only and is beneficial for the patient as it can provide more accurate radiation treatment than the standardised treatment with fewer CT examinations and possibly a more cost-effective radiation treatment process.

  5. 4. The future noise mapping model in Sweden

    University essay from KTH/Teknisk akustik

    Author : Johanna Sturk; [2022]
    Keywords : Mechanics; Acoustics; Noise Emission; Noise Mapping Model; CNOSSOS; Nordisk beräkningsmodell; Mekanik; Akustik; Buller; Beräkningsmodell; CNOSSOS; Nordisk beräkningsmodell;

    Abstract : An extensive technological shift is currently taking place to mitigate climate changeand this trend is particularly noticeable in the transport sector. This is interestingfrom an acoustical perspective, since it changes the noise environment in society. READ MORE

  6. 5. Investigation of a Collapsed Cone Superposition Algorithm for dosimetry in brachytherapy

    University essay from Stockholms universitet/Fysikum

    Author : Freja Alpsten; [2021]
    Keywords : Brachytherapy; Collapsed Cone; Model-Based Dose Calculation Algorithms; Radiotherapy;

    Abstract : Background & Purpose: The current standard dosimetry in brachytherapy treatment planning, the TG-43 formalism, ignore the presence of non-water media and finite patient dimensions. This can cause clinically relevant errors in dose estimates. READ MORE
