  1. 1. The pricing accuracy of the unbiased RIV model

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för redovisning och finansiering

    Författare :Jonny Jin; Daniel Klingberg; [2023]
    Nyckelord :Pricing accuracy; Residual income valuation; Unbiased accounting; Accounting measurement bias; Conservative accounting;

    Sammanfattning : This paper aims to investigate whether the pricing accuracy of the RIV model is improved with unbiased accounting. The introduction of the Feltham-Ohlson model has left researchers with an eagerness to propose a RIV model with high pricing accuracy. LÄS MER

  3. 2. Physiology-Guided Machine Learning for Improved Reliability of Non-Invasive Assessment of Pulmonary Hypertension

    Master-uppsats, Linköpings universitet/Avdelningen för medicinsk teknik

    Författare :Frida Hermansson; [2023]
    Nyckelord :Pulmonary Hypertension; pulmonary hypertension; improving; physiological-guided; machine learning; neural networks; NN; artificial neural networks; non-invasive; PH; tricuspid regurgitation; peak tricuspid regurgitation velocity; tricuspid regurgitation velocity; right ventricular systolic pressure; VGG16; Unet; TR-CNN; CNN; pulmonell hypertension; förbättra; fysiologisk-guidning; neurala nätverk; trikuspidal regurgitation; maximal trikuspidal regurgitation; icke-invasivt;

    Sammanfattning : Diagnosing pulmonary hypertension (PH) with right heart catheterization (RHC) is associated with a risk for complications and high expenses, leading to late diagnoses [1]. Transthoracic echocardiography can be used to assess non-invasive indicators for PH such as right ventricular systolic pressure (RVSP), which can be estimated by combining the peak tricuspid regurgitation velocity (TRV) with the estimated right arterial pressure (RAP).

    Sammanfattning : This thesis investigates abnormal returns over the period 1983-2021 from an investment strategy that is based on public accounting information. Investment positions are taken in US manufacturing firms and are held for 36 months using a self-financing (hedged) portfolio. LÄS MER

  5. 4. Symptom persistence of ADHD and quality assessment of measurements : A scoping review

    Uppsats för yrkesexamina på avancerad nivå, Linnéuniversitetet/Institutionen för psykologi (PSY)

    Författare :Elin Jonsson; Matilda Holmgren; [2023]
    Nyckelord :ADHD; Symptom persistence; Review; Open Science; Risk of bias; ADHD; Symtomstabilitet; Översikt; Open Science; Risk för bias;

    Sammanfattning : Background: Despite the high prevalence of ADHD, results of research on persistence rates remain scattered. Previous studies identify methodological limitations resulting in various developmental trajectories of ADHD symptoms. LÄS MER

  7. 5. A novel clinical test of pointing acuity withopen and closed eyes  a validity study

    Master-uppsats, Luleå tekniska universitet/Institutionen för hälsa, lärande och teknik

    Författare :Benjamin Hägglund; [2023]
    Nyckelord :proprioception; hand; validity; Qualisys Motion Capture QTC ; Leap Motion Controller LMC ;

    Sammanfattning : Hand proprioception is crucial for daily activities and may be compromised by diseases or injuries,impacting patients' independence. The lack of feasible, accurate, and affordable clinical tools forhand proprioception assessment poses a significant challenge, essential for identifying dysfunctionand evaluating treatment effects.
