A case study on the feasibility and performance of an UWB-AoA real time location system for resources management of civil construction projects
The application of integrated satellite and modern wireless positioning technologies for ubiquitous real-time resources management in large scale civil engineering projects can greatly optimize the time and cost in the construction process, and is now the trend for modern construction project management. As the outdoor conditions of most civil construction sites are open to sky, satellite posit...
متن کاملIndoor User Localization for Rapid Information Access and Retrieval on Construction Sites
Manual search of project information on construction sites is a tedious and timeconsuming process. Evolving technologies such as location-aware computing offer significant potential of improving such processes and supporting important decision-making tasks in the field. For example, rapid and convenient access to contextual project information, through continuous position tracking of engineers,...

متن کاملDesign and Miniaturization of a Novel Fractal Microstrip Antenna for UWB Applications
A novel printed octagonal fractal microstrip antenna with semi-elliptical ground plane is presented for ultra wide band applications. The proposed antenna has a compact size of 20×20×1 mm³. The measured result of the antenna exhibits the ultra wide band characteristics from 2/9 to 14/2 GHz. In this paper, reducing antenna’s size by 35%, the same results were achieved, while small dimension frac...
متن کاملDesign and Analysis of Ultra-wide Band Bandpass Filter Using Spiral Stub-Loaded Triple-Mode Resonator with a Notched Band
An ultra-wide band band-pass filter using novel spiral stub-loaded triple-mode resonator (SSLTMR) is presented. New spiral stub loaded resonator is analyzed with odd and even modes analysis for this class of BPF, achieving higher band wide and size reduction. In order to have a good response characterized, two (SSL-TMRs) and two quarter wavelength digital coupled lines are used. This new design...
