   Författare :Margarida M. Silva; Alexander Medvedev; Teresa Mendonça; Torbjörn Wigren; Robain De Keyser; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; anesthesia; drug delivery; feedback control; nonlinear modeling; pharmacokinetics pharmacodynamics; PID control; system identification; Wiener model; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

   Sammanfattning : General anesthesia is a drug-induced reversible state where neuromuscular blockade (NMB), hypnosis, and analgesia (jointly denoted by depth of anesthesia - DoA) are guaranteed. This thesis concerns mathematical modeling and feedback control of the effect of the muscle relaxants atracurium and rocuronium, the hypnotic propofol, and the analgesic remifentanil. LÄS MER

3. 22. Modeling of Multiple-Input Multiple-Output Radio Propagation Channels

   Författare :Kai Yu; KTH; []
   Nyckelord :Antenna Array; Wireless Communications; MIMO Channel Model; MIMO Channel Measurements; MIMO Channel Capacity;

   Sammanfattning : In recent years, multiple-input multiple-output (MIMO)systems appear to be very promising since they can provide highdata rates in environments with sucient scattering byexploiting the spatial domain. To design a real MIMO wirelesssystem and predict its performance under certain circumstances,it is necessary to have accurate MIMO wireless channel modelsfor dierent scenarios. LÄS MER

4. 23. Cavity Field Control for High-Intensity Linear Proton Accelerators

   Författare :Olof Troeng; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Particle Acceleration; Automatic Control; European Spallation Source;

   Sammanfattning : The European Spallation Source will, once fully operational in 2025, be the world's brightest neutron source. The neutrons will be generated by bombarding a tungsten target with protons accelerated to 96\% the speed of light by electromagnetic fields confined in 155 radio-frequency cavities along the world's most powerful linear accelerator.

   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; capacity; Wireless communications; performance bounds; distributed sources; generalized beamforming; channel estimation; MIMO; training;

   Sammanfattning : The focus of this thesis is on channel estimation in wireless communication systems that employ multiple antennas.The thesis is divided into two parts, whereof the first part addresses theproblem of parameter estimation of distributed sources. Due to, e.g. LÄS MER

7. 25. Verification of wireless communication performance and robustness for automotive applications

   Författare :Mikael Nilsson; Kommunikationsteknologi; []
   Nyckelord :Vehicle-to-Vehicle; V2V; channel modeling; path loss; two-ray; obstruction; large scale fading; shadow fading; multiple links; diversity; correlation; over-the-air; OTA; multi-probe; multipath propagation simulator; fading emulation;

   Sammanfattning : Today's test methods used for verifying the performance and robustness of automotive applications using wireless communication are often based on fieldtrails, which are time consuming, costly, and not repeatable. Therefore, there is an urgent need for new verification methods that can be performed in lab environment, where the realistic radio propagation environment can be emulated. LÄS MER
