  1. 1. Improving Objectivity and Reliability of Observational Risk Assessment Tools by using Technical Instruments

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Cephas Charsmar-Etor; [2023]
    Keywords : Direct measurement instruments; Observational instruments; Body segments and postures; Inertial measurement unit; Wearable sensors;

    Abstract : Ergonomic assessments to determine risks of work-related musculoskeletal disorders as well as to compare designs of work-tasks and workstations, are imperative for high sustainability and productivity in any given industry. Hence, assessment tools that can objectively and reliably capture postures, joint angles and muscle activities play very important role in properly determining risks relating to work and various tasks.

  3. 2. Using forest reflectance modelling to estimate albedo for narrow-view satellites

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap; Lunds universitet/Fysiska institutionen

    Author : Nick Bergmans; [2023]
    Keywords : satellite; remote sensing; albedo; surface reflectance; vegetation; forest; machine learning; albedo estimation; Earth and Environmental Sciences;

    Abstract : Surface albedo estimations from remote sensing are invaluable for energy balance descrip- tions in climate research. The aim of this work is to evaluate the possibility of using Sentinel-2 satellite data to get the total albedo of a small, vegetated area. READ MORE

  4. 3. Capillary Blood Flow Measurement based on Nail-fold Microscopic Images using Feature Based Velocity Estimation

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

  5. 4. PIV Investigation of the Intake Flow in a Parallel Valves Diesel Engine Cylinder

    University essay from KTH/Mekanik

    Author : Jean Rabault; [2015]
    Keywords : Admission stroke; Flow in cylinder; Swirl motion; Admission channels;

    Abstract : Preliminary designs for the cylinder heads of Scania’s next generation Diesel Engine have been investigated by the means of PIV measurements on a steady test rig. General structures present in the flow have been investigated, with a specific focus on Swirl motion due to its well documented impact on combustion efficiency and pollution generation. READ MORE

  6. 5. Bayesian Optimal Pure Tone Audiometry with Prior Knowledge

    University essay from KTH/Ljud- och bildbehandling

    Author : Nan Guan; [2011]
    Keywords : ;

    Abstract : Pure tone hearing threshold measurement is the most basic and common test for diagnosis of hearing loss and for compensation of the loss with hearing instruments. Pure-tone hearing thresholds are usually assessed using a simple standardized method. READ MORE
