  1. 1. Sensing the environment : development of monitoring aids for persons with profound deafness or deafblindness

    Författare :Parivash Ranjbar; Dag Stranneby; Erik Borg; Charlotte M. Reed; Örebro universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Auditive identification; Deaf; Deafblind; Directional perception; Environmental sound; Filtering; Frequency transposing; Hearing aid; Hearing impairment; Modulating; Monitoring; Tactile perception; Vibratory aid; Vibratory identification; Electronics; Elektronik; TECHNOLOGY; TEKNIKVETENSKAP; Elektronik; Electronics;

    Sammanfattning : Earlier studies of persons with deafness (D) and/or deafblindness (DB) have primarily focused on the mobility and communication problems. The purpose of the present study was to develop technology for monitoring aids to improve the ability of persons with D and/or DB to detect, identify, and perceive direction of events that produce sounds in their surroundings.

  3. 2. Adaptive Concatenated Coding for Wireless Real-Time Communications

    Författare :Elisabeth Uhlemann; Högskolan i Halmstad; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Incremental redundancy hybrid ARQ; Multiple concatenated codes; Iterative decoding; Rate compatible punctured codes; Union bounds; EXIT charts; Convergence analysis; Wireless real-time communication; Quality of service; TECHNOLOGY; TEKNIKVETENSKAP; convergence analysis; quality of service; rate compatible punctured codes; multiple concatenated codes; iterative decoding; wireless real-time communication; incremental redundancy hybrid ARQ; union bounds;

    Sammanfattning : The objective of this thesis is to improve the performance of real-time communication overa wireless channel, by means of specifically tailored channel coding. The deadlinedependent coding (DDC) communication protocol presented here lets the timeliness and thereliability of the delivered information constitute quality of service (QoS) parametersrequested by the application.

  4. 3. Compliance Control of Robot Manipulator for Safe Physical Human Robot Interaction

    Författare :Muhammad Rehan Ahmed; Ivan Kalaykov; Kystof Kozlowksi; Örebro universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Physical human robot interaction; collision safety; variable stiffness actuators; compliance control; TECHNOLOGY; TEKNIKVETENSKAP; Automatic control; Reglerteknik; Reglerteknik; Automatic Control;

    Sammanfattning : Inspiration from biological systems suggests that robots should demonstrate same level of capabilities that are embedded in biological systems in performing safe and successful interaction with the humans. The major challenge in physical human robot interaction tasks in anthropic environment is the safe sharing of robot work space such that robot will not cause harm or injury to the human under any operating condition.

  5. 4. An Automotive Lane Guidance System

    Författare :Andreas Eidehall; Fredrik Gustafsson; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active safety; Collision avoidance; Lane guidance; State estimation; Target tracking; Kalman filter; Centralized filtering; Threat assessment; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Automotive lane guidance systems, usually referred to as Lane Keeping Aid or Lane Keeping System, are designed to prevent or warn the driver of lane departure. They typically use a buzzer to alert the driver or a steering wheel torque to actually steer the vehicle back into the center of the lane. LÄS MER

  7. 5. Data Mining and Analysis for Characterizing Paper from On-line Multisensor Measurements

    Författare :Marcus Ejnarsson; Adas Gelzinis; Högskolan i Halmstad; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Feature Extraction; Kernel Based Novelty Detection; Kernel CCA; Monitoring; Newsprint; Paper Web; Time-Series Representation; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The objective of this thesis is to develop a multi-resolution tool for screening paper formation variations, aiming to detect abnormalities in various frequency regions ranging from millimeters to several meters. The abnormalities detected in different frequency regions give an indication for the paper maker about specific disturbances in the paper production process. LÄS MER
