  1. 36. Compensation for hearing loss and cancellation of acoustic feedback indigital hearing aids

    Författare :Johan Hellgren; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The development of integrated circuits during the last decades has made it possible to incorporate digital signal processing in hearing aids that fit into the ear canal and are powered by small zink-air batteries. The digital signal processing provides new possibilities for the hearing aid to modify the signal to fit the impaired ear. LÄS MER

  3. 37. Stochastic Event-Based Control and Estimation

    Författare :Toivo Henningsson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; event-based control; event-based estimation; sporadic control; stochastic control; stochastic hybrid systems; sum-of-squares methods; control over networks; quantized measurements;

    Sammanfattning : Digital controllers are traditionally implemented using periodic sampling, computation, and actuation events. As more control systems are implemented to share limited network and CPU bandwidth with other tasks, it is becoming increasingly attractive to use some form of event-based control instead, where precious events are used only when needed.

  4. 38. Extended target tracking using PHD filters

    Författare :Karl Granström; Thomas Schön; Fredrik Gustafsson; Ba-Ngu Vo; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The world in which we live is becoming more and more automated, exemplified by the numerous robots, or autonomous vehicles, that operate in air, on land, or in water. These robots perform a wide array of different tasks, ranging from the dangerous, such as underground mining, to the boring, such as vacuum cleaning. LÄS MER

  5. 39. Molecular methods in malaria control in the era of pre-elimination

    Författare :Ulrika Morris; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Increased funding combined with effective malaria control methods for prevention, diagnosis, and treatment, has resulted in a 30% reduction of the global malaria burden over the last decade. As malaria prevalence declines in areas of successful malaria control, the proportion of subpatent infections that fall below the detection level of malaria rapid diagnostic tests (RDTs) and microscopy increases.

  7. 40. Low-Power Delta-Sigma Modulators for Medical Applications

    Författare :Ali Fazli Yeknami; Atila Alvandpour; Martin Anderson; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Biomedical electronics has gained significant attention in healthcare. A general biomedical device comprises energy source, analog-to-digital conversion (ADC), digital signal processing, and communication subsystem, each of which must be designed for minimum energy consumption to adhere to the stringent energy constraint.
