Urban street systems are the essential part of the city. It has many functions including traffic, street landscape, free-barrier route for accessible entrances, and road/street signs, etc. Urban street systems play an important ecological and landscape function in cities. Especially street landscape, free-barrier accessibilities and street signs have received increasing attention over the past decade...
Proper classification of emergency materials is essential to build an emergency reserve. According to two new dimensions, which are both the importance of emergency materials and the difficulty degree of market access, emergency materials are divided into nine categories. This paper evaluates the emergency materials using the fuzzy comprehensive evaluation method so as to determine the classification...
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.
A selection is presented of fiber-optic and micro-optic devices that have been designed and tested for guaranteeing the quality and safety of typical foods, such as extra virgin olive oil, beer, and milk. Scattered colorimetry is used to authenticate various types of extra virgin olive oil and beer, while a fiber-optic-based device for UV-VIS-NIR absorption spectroscopy is exploited in order to obtain...
