  2. 11. Essays on antibiotics use: Nudges, preferences & welfare benefits

    Author : Linnea Wickström Östervall; Jakob Svensson; Astri Muren; Kjetil Bjorvatn; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; field experiment; nudge; reminder; common resources; antibiotics use; resistance; altruism; other-regarding preferences; time preferences; social security; temporary parental leave; natural experiment; Economics; nationalekonomi;

    Abstract : The stock of effective antibiotics can be seen as a common resource. Depletion of this potentially renewable, but currently finite, resource through the development of resistance poses an important policy problem. Prudent use can delay the spread of resistance. It is hence interesting to study factors that affect use and overuse of antibiotics. READ MORE

  4. 12. Design of Wireless Communication Systems -- Issues on Synchronization, Channel Estimation and Multi-Carrier Systems

    Author : Fredrik Tufvesson; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pre-compensation; pilot pattern; Elektronik; orthogonal frequency division multiplex; Wireless; synchronization; detection; preambles; channel estimation; Electronics; superimposed pilot sequences; sub-channel bandwidth; precoding;

    Abstract : This thesis deals with certain aspects in the design of wireless communications systems. It is focused on problems related to the mobile or wireless channel: synchronization, channel estimation and design of wireless orthogonal frequency division multiplex (OFDM) systems. READ MORE

  5. 13. Steady State Operation and Control of Power Distribution Systems in the Presence of Distributed Generation

    Author : Ferry Viawan; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; distance protection; stochastic assessment; voltage dip; line drop compensation; distribution systems; on-load tap changer; overcurrent protection; sensitive equipment; voltage dip immunity; voltage control; short circuit; reactive power control; pilot protection.; protection coordination; protection; Distributed Generation; losses;

    Abstract : In this thesis, the impact of distributed generation (DG) on steady state operation and control of power distribution systems is investigated. Over the last few years, a number of factors have led to an increased interest in DG schemes. DG is gaining more and more attention worldwide as an alternative to large-scale central generating stations. READ MORE

  6. 14. Volterra modeling of the human smooth pursuit system in health and disease

    Author : Viktor Bro; Alexander Medvedev; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Abstract : This thesis treats the identification of Volterra models of the human smooth pursuit system from eye-tracking data. Smooth pursuit movements are gaze movements used in tracking of moving targets and controlled by a complex biological network involving the eyes and brain. READ MORE

  7. 15. Wideband Sigma-Delta Modulators

    Author : Xiaolong Yuan; Svante Signell; Jakob Wikner; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sigma-delta modulator; feedforward; reconfigurable; quadrature bandpass filtering; Electronics; Elektronik;

    Abstract : Sigma-delta modulators (SDM) have come up as an attractive candidatefor analog-to-digital conversion in single chip front ends thanks to the continuousimproving performance. The major disadvantage is the limited bandwidthdue to the need of oversampling. READ MORE
