—In this paper the simulation of ultra wideband microstrip antenna is considered. Because of the ultra wideband characteristics of this antenna, it is better to use time domain simulation methods. In this work we use three dimensional transmission line matrix method (3D-TLM) and EPML-TLM algorithm for modeling PML boundary condition directly applied to TLM(More)
802.11n-based Wireless Local Area Networks (WLANs) are likely to be used in a network that also accommodates other legacy devices. This heterogeneous deployment of different technologies in the same area raises a legitimate question about the effect of legacy nodes on the 802.11n high throughput ones and consequently on the overall network performance. This(More)
Nowadays, many leading construction companies are still using 2D drawings, Microsoft Excel or other spreadsheet programs to prepare tenders regarding MEP trades. 2D drawings are scanned and the quantities of commodities are extracted and imported into spreadsheet programs. This method is not accurate and transparent. In addition, too much time and effort is(More)
