Byoungduk Lee,Seungyoun Yang,Jaekwon Shin,Jintae Kim,Seonhee Lee 한국위성정보통신학회 2017 한국위성정보통신학회논문지 Vol.12 No.1
In this paper we present the combination of location based mobile advertisement services and dynamic digital signage markets has been developing recent days to provide consumer admired visual mobile advertisement on all kind transportation vehicles. In spite of that, the digital signage advertisement content management is still not that easy to manage the content dynamically as well operation is most time consuming to handle the contents dynamically in digital signage business. As location based services is most impactful service in shopping, the location responsive advertisement on vehicle signage will be most desirable mobile advertisement to help people migrate from one place to another place for travel or stay. This paper propose a mobile location responsive digital signage system for vehicles using the GPS and wireless infrastructure integrated with digital signage system. This proposed research use the centralized digital signage system architecture for the mobile advertisement application and this system can be expanded to different vehicles for digital advertisement including buses, trucks, train, air vehicle and any other form of mobile advertising vehicles. Also, this present an effective advertisement recommendation algorithm, by which the advertisement can be selected broadcasted for the right advertisement ventures more effectively as the service requested from advertiser. This paper present the emulated experimental result to evidence the proposed dynamic vehicle signage system performed better than compared with traditional signage random advertising. The emulated result proves that the advertisement recommendation algorithm can effectively works out the targeted key audiences in location responsive region the algorithm evaluated

We demonstrate a thin metal-dielectric structure that delivers low reflection and high absorption over the entire visible spectrum. The thin black film consists of SiO2/Cr/SiO2/Al layers deposited on a glass substrate. The measured reflectance and absorptance of the black film are 0.7% and 99.3%, respectively, when averaged over the range 380 – 780 nm. The total thickness of the black film is only about 220 nm, and it can be used as a thin absorbing layer for displays that require both broadband antireflection and high-contrast characteristics.
