  1. 1. Validation of a new iPhone application for measurements of wrist velocity during actual work tasks

    Master-uppsats, KTH/Ergonomi

    Författare :Mohammed Abderhman Abaid; [2023]
    Nyckelord :Angular velocity; goniometer; inertial Measurement Unit IMU ; “ErgoHandMeter”; percentile; correlation iii; Vinkelhastighet; goniometer; IMU ; ErgoHandMeter ; percentil; korrelation;

    Sammanfattning : The breakthrough in mobile technology and the development of smartphones, supplied with sensing devices such as Inertial Measurement Units (IMUs), has made it possible to obtain accurate and reliable data on the angular velocity for different objects. The available technical sensors for wrist movements, such as electrogoniometers, are costly, time-consuming, and need a particular computer program to be analyzed. LÄS MER

  3. 2. Arm Injury Prediction with THUMS SAFER: Improvements of the THUMS SAFER upper extremity

    Master-uppsats, KTH/Hållfasthetslära; KTH/Lättkonstruktioner

    Författare :Mariam Bayat; Nichakarn Pongpairote; [2020]
    Nyckelord :Biomechanics; upper extremity; arm; validation; Total HUman Model for Saftey THUMS ; Finite Element Modelling FEM ; Biomekanik; övre extremitet; arm; validering; Total HUman Model for Saftey THUMS ; Finite Element Modellering FEM ;

    Sammanfattning : Globally, approximately 1.2 million people die each year due to traffic accidents. Upper extremity injuries account for 18% to 25% of all car accident injuries. In order to be able to analyze these crash-related injuries, Human body models(HBMs) are used as a complement to FE simulations. LÄS MER

  4. 3. Modeling of Effective Leaf Area Index

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Forest Resource Management

    Författare :Lina Selin; [2018]
    Nyckelord :Sentinel-1; tree species; random forest; linear discriminant;

    Sammanfattning : Mapping of e�ective leaf area index (LAIe) over the Swedish boreal forest test site Krycklan (64°N19°E) was performed using ground-based �eld estimates of LAIe and remote sensing data sources. The LAIe data were collected 2017 and 2018 using the LAI-2200 Plant Canopy Analyzer and its later version LAI-2200C Plant Canopy Analyzer. LÄS MER

  5. 4. Finite Element Modeling of Skull Fractures : Material model improvements of the skull bone in theKTH FE head model

    Master-uppsats, KTH/Skolan för teknik och hälsa (STH)

    Författare :Frida Andersson; [2016]
    Nyckelord :;

    Sammanfattning : The main aim of this project was to develop a model for predicting skull fractures of a 50th percentile male, using a finite element head model developed at the Neuronics department of KTH, Royal Instituteof Technology. The skull bone is modeled as a three layered bone, where the outer and inner tables are modeled as shell elements, while the diploë is modeled by two layers of solid elements. LÄS MER

  7. 5. Driving Cycle Generation Using Statistical Analysis and Markov Chains

    Master-uppsats, Fordonssystem; Tekniska högskolan

    Författare :Emil Torp; Patrik Önnegren; [2013]
    Nyckelord :drive cycle; mean tractive force; cluster analysis; regression analysis; percentile validation; transition probability matrix;

    Sammanfattning : A driving cycle is a velocity profile over time. Driving cycles can be used for environmental classification of cars and to evaluate vehicle performance. The benefit by using stochastic driving cycles instead of predefined driving cycles, i.e. LÄS MER
