Ant Colony Optimisation algorithm a multi-agent approach to combinatorial optimisation problems is used for a simple ray tracing performed on only an ordinary bitmap of the city map. Together with the Berg’s recursive model a non-line-of-sight path loss could be calculated without any need of building database. In this way the coverage predictions for urban microcells could become extremely eas...

The city is the base and the space for people to come together. The space in which human interaction and social affairs occur and is identified in terms of epistemic and ontological support. So that we can talk about beautiful city, industrial city, western city and Islamic city. This paper uses the method of thematic analysis to explain the Islamic city by analyzing the relevant sources ...

Achieving high performance on modern CPUs requires efficient utilization of SIMD units. Doing so requires that algorithms are able to take full advantage of the SIMD width offered and to not waste SIMD instructions on low utilization cases. Ray tracers exploit SIMD extensions through packet tracing. This re-casts the ray tracing algorithm into a SIMD framework, but high SIMD efficiency is only ...

With the rapid growth of information and communication technologies, the attempt for more convenient, safe, and sustainable urban development has been going around the world. The Korean government has launched a R&D project to develop a new software platform that supports the smart city applications such as transportation, anti-disaster, anti-crime, and eco-friendly environment. This paper repo...

The increase in mobile communications traffic has led to heightened interest in the use of ray tracing (RT) methods together with digital building databases for obtaining more accurate and efficient propagation prediction in urban microcellular environments. In this paper, a novel quasi three-dimensional (3-D) RT algorithm is presented by taking into account the advantages of both the image the...

Two different confocal micro X-ray fluorescence spectrometers have been developed and installed at Osaka City University and the Vienna University of Technology Atominstitut. The Osaka City University system is a high resolution spectrometer operating in air. The Vienna University of Technology Atominstitut spectrometer has a lower spatial resolution but is optimized for light element detection...
