2. 6. Acoustic separation and electrostatic sampling of submicron particles suspended in air

   Author : Ramin Imani Jajarmi; Etienne Robert; Lisa Prahl Wittberg; Laszlo Fuchs; Martin Wiklund; Klas Engvall; Jeremy Hawkes; Michel Cervantes; Mats Åbom; Olga Roditcheva; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustic; separation; acoustophoresis; Engineering Mechanics; Teknisk mekanik;

   Abstract : We investigate experimentally the effects of acoustic forces on submicron aerosol in a channel flow. This technique can potentially overcome some of the limitations of conventional separation systems and provide advanced manipulation capabilities such as sorting according to size or density.

4. 7. Augmenting L1 Adaptive Control of Piecewise Constant Type to Aerial Vehicles

   Author : Anders Pettersson; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : In aerial vehicle control design, the industrial baseline is to use robust control methods together with gain-scheduling to cover the full airspeed and altitude flight envelope. An adaptive controller could possibly add value by increasing performance while keeping robustness to deviation from nominal assumptions. READ MORE

5. 8. Programmable and Tunable Circuits for Flexible RF Front Ends

   Author : Naveed Ahsan; Aziz Ouacha; Sten Gunnarsson; Linköpings universitet; []
   Keywords : Microwave circuits; phase shifters; programmable circuits; active corporate feed network; four-port circuit; generic cells; phase shift capability; programmable microwave function array; tunable recursive filter; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : Most of today’s microwave circuits are designed for specific function and specialneed. There is a growing trend to have flexible and reconfigurable circuits. Circuitsthat can be digitally programmed to achieve various functions based on specific needs. READ MORE

6. 9. Some studies on metamaterial transmission lines and their applications

   Author : Xin Hu; Sailing He; Ferran Martin; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metamaterial; transmission line theory; composite right left-handed transmission line; diplexer; coupler; balun; interdigital capacitor; split ring resonator; Electrical engineering; Elektroteknik;

   Abstract : This thesis focuses mostly on investigating different potential applications of meta-transmission line (TL), particularly composite right/left handed (CRLH) TL, and analyzing some new phenomena and applications of meta-TL, mostly left-handed (LH) TL. Realization principle will also be studied. READ MORE

7. 10. Remedial Injection Grouting of Embankment Dams with Non-Hardening Grouts

   Author : Johan Lagerlund; Håkan Stille; Sven Knutsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The focus of this thesis is to study the possibility of injection grouting of embankment dams affected by internal erosion. Internal erosion is a process where certain soil material from an embankment dam is removed. This phenomenon occurs in the central core of the embankment dam. READ MORE
