    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

    Sammanfattning : Early detection is vital to successfully treating breast cancer, and mammography screening is the most efficient and wide-spread method to reach this goal. Imaging low-contrast targets, while minimizing the radiation exposure to a large population is, however, a major challenge. LÄS MER

  5. 4. 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 :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.
