The command-based interface of importance biasing technique has been developed using Geant4 for shielding applications. The purpose of this study is to develop a tool for calculating spatial dose distributions in radiation therapy facilities for radiation protection. The primary method of radiation control is to design physical features of shielding and barriers in radiological areas. Monte Carlo...
Since the aviation safety information contains both structured and textual data, this paper proposed a strategy for creating aviation safety dictionary. It used the maximum match algorithm based on segmentation unit to obtain the candidate word set and adopted the mutually information to improve the word extraction accuracy in cooperation with domain specialists. Experiments showed that the created...
The construction industry has been facing a paradigm shift to (i) increase; productivity, efficiency, infrastructure value, quality and sustainability, (ii) reduce; lifecycle costs, lead times and duplications, via effective collaboration and communication of stakeholders in construction projects. Digital construction is a political initiative to address low productivity in the sector. This seeks...
This paper discusses the manner in which cinema buildings of the 20th century represent both an important physical record of society, and a challenge in terms of representing a complex range of historical, cultural, economic and physical data sets.The paper provides an overview of visualisation techniques which are appropriate to the subject, and provides a case study taken from the city of Aberdeen...
This paper presents a structural health monitoring system for monitoring, with reduced visual impact, one historical building structure. The system is based on fiber Bragg gratings and comprises 19 displacement sensors and 5 temperature sensors. All the sensors were custom made according to the monitoring points' characteristics. The results obtained over the first year of monitoring are presented...
We present the use of swept wavelength interferometry for distributed fiber-optic temperature measurements in a nuclear reactor. The sensors consisted of 2-m segments of commercially available, single mode optical fibers. The interrogation technique is based on measuring the spectral shift of the intrinsic Rayleigh backscatter signal along the optical fiber and converting the spectral shift to temperature.
