Ultra wideband omnidirectional discone antenna for WLAN applications

The focus of this thesis is to design a dielectric covered discone WLAN antenna working under the protocols of IEEE802.11 a/b/g/n. It has the wideband operation of discone antennas and the compact dimensions of dielectric resonator antennas which is compatible with the latest main protocol WLAN applications. This antenna has an ultra-wide...

Effect of mechanical fractionation and torrefaction on the biomass composition

In the Netherlands, green residues such as verge grass are a possible alternative to (partially) replace traditional fossil fuels. A feasible way of doing this, without large modification costs on existing power plants, is biomass co-firing. However, grass has high moisture content, poor grindability properties and high ash content, which have...
