  1. 1. Evaluation of Knee Ligament Injuries in Occupants of Heavy Goods Vehicles by Simulating Frontal Impacts using THUMS HBM

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

    Author : Jiota Nusia; [2019]
    Keywords : Frontal impacts; Cumulative injury risk curve; Ligament material curves; Total Human Model for Safety THUMS ; Hybrid III- model HIII ; Heavy Goods Vehicles HGV ; Validation; Knee joint; Posterior cruciate ligament PCL ; Medial collateral ligament MCL ; Lateral collateral ligament LCL .;

    Abstract : INTRODUCTION. Frontal collisions have been observed to cause the severe injuries on heavy goods vehicle occupants, and the lower extremities have been frequently injured. Injuries of knee joints are rarely life threatening, however they tend to give long-term consequences. AIM. READ MORE

  3. 2. Cloud Observations at a Coastal site – Analysis of Ceilometer Measurements from Östergarnsholm, Sweden

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Aron Stenlid; [2019]
    Keywords : Ceilometer; Stratocumulus; cloud base height; LCL; DLS; upwelling; cloud cover;

    Abstract : In this study, four and a half months of ceilometer data from Östergarnsholm are used to analyze cloud related to processes in the boundary layer. Measurements are divided into two categories, which are defined by wind direction: a continental and a marine sector. READ MORE

  4. 3. Design of Resonant Filters for AC Current Magnification : Heating of Li-ion Batteries by Using AC Currents

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

    Author : Nikolina Djekanovic; [2018]
    Keywords : Current control; injection of alternating current; internal heat dissipation; LCL filter; Lithium-ion batteries; power efficiency; resonance phenomenon;

    Abstract : Using alternating current in order to heat batteries at sub-zero temperatures is a method,which is investigated in-depth by an increasing number of study groups. The thesis considersthe resonance phenomenon with the intention to use alternating current amplificationand battery’s impedance in order to induce power dissipation inside the battery, and in thisway increase its temperature.
