As XML becomes more and more popular, easy-to-use and powerful XML query languages are in great need. Xing is a visual query and restructuring language for XML documents. The objective of this project is to develop a basic version of Xing, including a user-oriented XML query interface and a simple...
The rolling resistance model has been employed in the discrete element modelling in geomechanics, as an alternative computationally efficient approach to capture the resistance of particle rotation due to irregularity in shape. This paper presents a series of 3D DEM simulations of triaxial compression tests on specimens with rolling resistance...
Ultra-wideband (UWB) communication has emerged as a very promising
technology for short-range wireless applications, including
high-speed multimedia transmissions and sensor networks. UWB
system designs involve many different aspects covering analog and
digital processing, channel estimation and modeling, and
modulation and demodulation. Although UWB still faces many
challenges, significant progress has...
