  2. 1. Sagittal plane knee translation in healthy and ACL deficient subjects : a methodological study in vivo with clinical implications

    Author : Anil Vergis; Jon Karlsson; Linköpings universitet; []
    Keywords : anterior cruciate ligament; electrogoniometer system; gait; knee; kinematics; motion analysis; step ascent; step descent; translation; MEDICINE; MEDICIN;

    Abstract : This study on human subjects, comprises of four cross sectional and one prospective cohort study. The general purpose of this work was to develop a technique for measuring in vivo, sagittal anterior-posterior translatory motions in the knee joint using a computerized electrogoniometer (CA-4000, OS Inc., Hayward CA, USA).

  4. 2. Positioning Algorithms for Surveillance Using Unmanned Aerial Vehicles

    Author : Per-Magnus Olsson; Patrick Doherty; Lars Karlsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Unmanned aerial vehicles; surveillance; communication relay; label- correcting; dual ascent; Steiner trees; Computer science; Datalogi;

    Abstract : Surveillance is an important application for unmanned aerial vehicles (UAVs). The sensed information often has high priority and it must be made available to human operators as quickly as possible. Due to obstacles and limited communication range, it is not always possible to transmit the information directly to the base station. READ MORE

  5. 3. The Fight on the Flights : Emergency evacuations – human physiological performance, leg muscle activity and gait biomechanics during exhaustive stair and slope ascent

    Author : Amitava Halder; Ergonomi och aerosolteknologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Stair climbing evacuation; Physical work capacity; Physiological constraints; Endurance; Energy expenditure; Oxygen consumption; Electromyography; Muscle fatigue; Incline gait biomechanics; Ground reaction forces; Required coefficient of friction;

    Abstract : Physical exhaustion can constrain stair ascending capacity during emergency evacuation. The overall aim of this research was to explore and compare stair ascending capacities and physiological limitations when using two different modes: 1) self-preferred pace on three different public stairways, and 2) four machine-controlled paces on a stair machine corresponding to different percentages of maximal aerobic capacity (V̇O2max).

  6. 4. Evaluation of physical work capacity and leg muscle fatigue during exhaustive stair ascending evacuation

    Author : Amitava Halder; Ergonomi och aerosolteknologi; []
    Keywords : Stair climbing; Energy expenditure; Oxygen consumption; Electromyography; Muscle fatigue;

    Abstract : AbstractPhysical exhaustion can constrain human ascending work capacity and performance during emergency evacuation on stairs. The overall aim of this research was to explore and compare stair ascending capacities and physiological limitations during two different strategies: self-preferred pace in three different public stairways in the field, and controlled pace in a laboratory on a stair machine.

  7. 5. Convex multicommodity flow problems : a bidual approach

    Author : Kristoffer Hägglöf; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Abstract : The topic of this dissertation, within the subfield of mathematics known as optimization, is the development of a new dual ascent method for convex multicommodity flow problems. Convex multicommodity flow problems arize in many different routing problems such as the design of packet switched computer networks and the computation of traffic network equilibria. READ MORE
