    Digital Image Processing Methods Applied to Remote Sensing Data for Ozone Analysis in an Industrial Region
    (Umweltinformatik '97, 1997) Scharinger, Josef; Pichler, Franz; Freigaßner, Robert
    This contribution deals with the problem how contemporary methods of digital image processing can be applied to remote sensing data and utilized to efficiently model and simulate the generation and spreading of ozone in an industrial region. The main points thereby are land use classification and the generation and computation of adequate elevation models. Based on a survey of the capabilities offered by modern satellites we also analyze in which way adequate informations concerning actual air pollution caused by traffic can be automatically obtained using image analysis and pattern recognition. Dieser Beitrag befaßt sich mit der Fragestellung, wie mittels der Methoden der Digitalen Bildverarbeitung Fernerkundungsdaten zur effizienten Modellierung und Simulation der Ozonausbreitung in einem Industriegebiet herangezogen werden können. Das Hauptaugenmerk liegt dabei auf der Datenerhebung für Landnutzung und Orographie. Ausgehend von den technischen Möglichkeiten moderner Satelliten wird jedoch auch analysiert, in welcher Form weitere geeignete Daten, insbesondere aktuelle Schadstoffdaten über das Verkehrsaufkommen, mittels Bildauswertung automatisch generierbar sind.

    Near Field Communication based Mobile Payment System
    (Mobile und Ubiquitäre Informationssysteme – Technologien, Prozesse,Marktfähigkeit – Proceedings zur 3. Konferenz Mobile und Ubiquitäre Informationssysteme (MMS 2008), 2008) Madlmayr, Gerald; Scharinger, Josef
    In daily life, ordinary cash is more and more replaced by electronic means of payment. Where on the one hand side macro payment systems are well covered by credit cards, micro payment systems still suffer from different technological and usability issues. Besides usability, security in payment systems has always been a hot topic ever since. In this paper we present a new, promising approach for a purse-based micro pay- ment system. Our system relies on a prepaid wallet having the money stored in a se- cure chip in the mobile phone. The proximity technology Near Field Communication (NFC) is used to conduct contactless payment transactions at the point of sale (POS). Additionally the wallet can be topped up over the air (OTA), anywhere and anytime. The combination of OTA top-up and NFC payment transactions make this system very convenient as the data acquired during an eight month trial shows. Users benefit from the system as they do need to head for an ATM to load money into the wallet. This system is also advantageous for banks and payment providers as there is no need to issue smartcards. Besides the technological aspects of NFC and the implementation of the payment system, this paper also presents the results of an eight month trial with 75 participants.
