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

    Author : Parivash Ranjbar; Dag Stranneby; Erik Borg; Charlotte M. Reed; Örebro universitet; []
    Keywords : 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;

    Abstract : 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.

  4. 2. Low and Medium Level Vision Using Channel Representations

    Author : Per-Erik Forssén; Gösta Granlund; Jim Little; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This thesis introduces and explores a new type of representation for low and medium level vision operations called channel representation. The channel representation is a more general way to represent information than e.g. as numerical values, since it allows incorporation of uncertainty, and simultaneous representation of several hypotheses.

  6. 4. Internal Dosimetry in Nuclear Fuel Fabrication : Occupational Exposure to Uranium Aerosols

    Author : Edvin Hansson; Mats Eriksson; Håkan Pettersson; Per Roos; Michael Sandborg; Bastian Breustedt; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Uranium; Aerosol; Internal; Dose; Nuclear;

    Abstract : The production of nuclear fuel can be associated with occupational exposure to ionizing radiation from radioactive decay of uranium. Such exposure must be sufficiently low and radiation doses adequately determined. Radiation doses from internal exposure, i.e. READ MORE

  7. 5. Inter-hospital transports of critically ill children

    Author : Tova Hannegård Hamrin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : There is an increasing need for inter-hospital transports of seriously ill children as a result of centralization of intensive care for children to dedicated pediatric intensive care units (PICU). This thesis has explored the short-and long-term outcomes of critically ill children after transport by a specialized pediatric transport team to a PICU. READ MORE
