1. 21. Towards Radio-Environment Aware IoT Networks : Wireless Coexistence Methods for Low-complexity Devices

   Författare :Simone Grimaldi; Mikael Gidlund; Aamir Mahmood; Tingting Zhang; Georgios Z. Papadopoulos; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; IoT; Industrial IoT; Interference; Machine Learning; Wireless Coexistence; Wireless Networks;

   Sammanfattning : Wireless technologies for short-range communication play a central role in the massive diffusion of the Internet of Things (IoT) paradigm. Such communication solutions rely extensively on the availability of unlicensed spectrum in the form of bands for industrial, scientific, and medical (ISM) applications. LÄS MER

3. 22. Design of Reliable Communication Solutions for Wireless Sensor Networks : Managing Interference in Unlicensed Bands

   Författare :Luca Stabellini; Jens Zander; Andreas Kassler; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

   Sammanfattning : Recent surveys conducted in the context of industrial automation have outlined that reliability concerns represent today one of the major barriers to the diffusion of wireless communications for sensing and control applications: this limits the potential of wireless sensor networks and slows down the adoption of this new technology. Overcoming these limitations requires that awareness on the causes of unreliability and on the possible solutions to this problem is created. LÄS MER

4. 23. Interference Cancellation for DS/CDMA Systems in Flat Fading Channels

   Författare :Ann-Louise Johansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mixed modulation; direct-sequence code division multiple access DS CDMA ; multiuser detection.; multiple data rates; parallel channels; multicode; interference cancellation;

   Sammanfattning : This thesis investigates interference cancellation in direct-sequence codedivision multiple access (DS/CDMA) systems that support multiple data rates.Two approaches for implementing multiple data rates are considered. Oneis the use of mixed modulation. The second is the use of parallel channels. LÄS MER

5. 24. Experimental Challenges in Wireless Sensor Networks — Environment, Mobility, and Interference

   Författare :Olof Rensfelt; Per Gunningberg; Torsten Braun; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless Sensor Networks; Testbed; Mobility; Interference classification; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

   Sammanfattning : Wireless sensor networks are used to collect sensor data in different applications such as environmental monitoring, smart building control, and health care applications. Wireless sensor nodes used are typically small, low-cost, and battery powered. LÄS MER

7. 25. Anti-paternalism

   Författare :Kalle Grill; Sven Ove Hansson; Torbjörn Tännsjö; KTH; []
   Nyckelord :HUMANIORA; HUMANITIES; paternalism; anti-paternalism; private sphere; self-regarding; harm principle; interference; reasons; actions; reason-actions; epistemic paternalism; public health; withholding of information; uncertain information; MCS multiple chemical sensitivity .; Philosophy subjects; Filosofiämnen;

   Sammanfattning : This is a thesis about anti-paternalism – the liberal doctrine that we may not interfere with a person’s liberty for her own good. Empirical circumstances and moral values may certainly give us reason to avoid benevolent interference. Anti-paternalism as a normative doctrine should, however, be rejected. LÄS MER
