In this paper, microstructure and properties of Cu/TiB2 composite coating from Ti, B, Cu pure powders on H13 steel prepared by in-situ laser cladding were studied. The experimental results showed that, in laser cladding process to manufacture coatings, Ti and B powders react to form dispersed TiB2 phase in the Cu matrix. The Energy Dispersive X-ray Spectroscopy (EDS) analysis showed that, a high-strength...
In this paper, we analyze the reconfigurable complex filtering techniques based on the Tone Reservation (TR) set and data bearing sub-carriers in the time-domain and in the frequency-domain to reduce the Peak-to-Average Power Ratio (PAPR) of OFDM signals. The simulation results of the proposed methods for 16-QAM and 64-QAM modulation are presented. These results show that PAPR of OFDM signals is significantly...
This chapter describes our experiences developing wireless, acoustic sensor network systems for a high rate sensing application: monitoring amphibian populations in northern Australia. Our goal was to use automatic recognition of animal vocalizations to census the populations of native frogs and an invasive introduced species, the Cane Toad. This application falls within the large class of detection...
