  1. 1. Low-Cost Navigation Systems : A Study of Four Problems

    Författare :Isaac Skog; Peter Händel; Fredrik Gustafsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Navigation; Inertial Navigation; Pedestrian Navigation; Inertial Measurement Unit; Time Synchronization; Signal processing; Signalbehandling;

    Sammanfattning : Today the area of high-cost and high-performance navigation for vehicles is a well-developed field. The challenge now is to develop high-performance navigation systems using low-cost sensortechnology. LÄS MER

  3. 2. Mobile Robot Traversability Mapping : For Outdoor Navigation

    Författare :Peter Nordin; Petter Krus; Jonas Nygårds; Nils Axel Andersen; Linköpings universitet; []
    Nyckelord :Traversability; Laser; Roughness; Mapping; Planning; Mobile robot; Navigation; Implementation;

    Sammanfattning : To avoid getting stuck or causing damage to a vehicle or its surroundings a driver must be able to identify obstacles and adapt speed to ground conditions. An automatically controlled vehicle must be able to handle these identifications and adjustments by itself using sensors, actuators and control software. LÄS MER

  4. 3. Augmented navigation

    Författare :Gustav Burström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Spinal fixation procedures have the inherent risk of causing damage to vulnerable anatomical structures such as the spinal cord, nerve roots, and blood vessels. To prevent complications, several technological aids have been introduced. LÄS MER

  5. 4. Recursive Bayesian Estimation : Navigation and Tracking Applications

    Författare :Niclas Bergman; Fredrik Gustafsson; Lennart Ljung; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Target tracking; Autonomous aircraft navigation; Terrain navigation;

    Sammanfattning : Recursive estimation deals with the problem of extracting information about parameters, or states, of a dynamical system in real time, given noisy measurements of the system output. Recursive estimation plays a central role in many applications of signal processing, system identification and automatic control. LÄS MER

  7. 5. Escaping 'death by GPS' : foundations for adaptive navigation assistance

    Författare :Fateme Teimouri; Kai-Florian Richter; Henrik Björklund; Sabine Timpf; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; wayfinding; navigation systems; navigation complexity; prominent locations; route generalization; spatial cognition; mental models; route learning; direction giving; Human-centered study.;

    Sammanfattning : Navigating through physical environments has evolved over time from using stars and maps to support the wayfinding, to employing Global Positioning Systems and navigation services. Turn-by-turn guidance of navigation services is an effective way to support wayfinding, but it may not align with the way humans naturally navigate. LÄS MER
