Joint design of PAPR, PICR and OBP in OFDM systems / by Kewei Yuan.
"Orthogonal frequency division multiplexing (OFDM) technique has been adopted by many existing and future wireless communication systems for high-speed data transmission. However, a major problem of OFDM systems is the ...
Evaluation of GaN and InGaN semiconductors as potentiometric anion selective electrodes / by Rozalina Dimitrova.
"Ion selective electrodes (ISEs) are chemical sensors primarily used for in situ analysis and monitoring of air, water, and land. Despite their easy fabrication, low cost, and simple usage, ISEs still suffer from the ...
Production of bio-crude from forestry waste by hydro-liquefaction in sub-/super-critical methanol and upgrading of bio-crude by hydro-treating / by Yun Yang.
"Bio-energy is renewable and clean (with trace amount of sulfur and neutral in terms of CO2 emission), and abundant in resource, thus it could be a securable and sustainable energy for future. Due to the declining reserve ...
Attitude estimation and control of a ducted fan VTOL UAV / by Andrew David Roberts.
"A significant area of current research is to develop aircraft which are unmanned. More specifically, some researchers are focusing on hovering type aircraft, or vertical take-off and landing (VTOL) aircraft. Since these ...
