In this paper, a novel algorithm for colour recovery is presented. It assumes that the 3-D geometry of the scene is known. The spectral power distribution of a point illumination source, and the response function of the sensor are calibrated jointly. This algorithm has been used for the colour recovery part of an integrated system, developed in our laboratory, for environmental modelling. The g...

Augmented tabletop games support players by sensing the context of game figures (i.e., position and/or orientation) and then using this information to display additional game information, or to perform game related calculations. In our work we try to detect the position and orientation of game figures using small, unobtrusive passive RFID tags. In order to localize our multi-tagged objects, we ...

Most emission metrics have previously been inconsistently estimated by including the climate– carbon feedback for the reference gas (i.e. CO2) but not the other species (e.g. CH4). In the fifth assessment report of the IPCC, a first attempt was made to consistently account for the climate–carbon feedback in emission metrics. This attempt was based on only one study, and therefore the IPCC concl...

This paper investigated various indoor positioning techniques and presented a comprehensive study about their advantages and disadvantages. Infrared, Ultrasonic and RF technologies are used in different indoor positioning systems. RFID positioning systems based on RSSI technology are the most recent developments. Positioning accuracy was greatly improved by using integrated RFID technologies.

Advanced location-based services (A-LBS) for humancentric tracking and monitoring are now emerging as operators and service providers begin to leverage their existing infrastructure and invest in new technologies, toward increasingly innovative location application solutions. We can now point to humancentric tracking and monitoring services where the person (i.e. subject) has become an active n...

Abstract The emerging “new space” age strengthens the importance of rapid development and qualification procedures electric engines their peripheral devices. A key element is reliable simulation thrusters supply units on short time scales. Global models seem to be well suited for this purpose. In article, three variants global are presented validated by comparison with experimental results. All...

This paper provides global climatology of high-frequency (T < 2 h) sea-level oscillations atmospheric origin. Sea-level series with a temporal resolution 1 min from 331 tide gauges in the world ocean and spanning between 1.5 12 years were analysed to determine typical ranges, seasons characteristics moderate extreme manifestations nonseismic at tsunami timescales (NSLOTTs). Variances these reac...

Abstract Assessing the role of anthropogenic warming from temporally inhomogeneous historical data in presence large natural variability is difficult and has caused conflicting conclusions on detection attribution tropical cyclone (TC) trends. Here, using a reconstructed long-term proxy annual TC numbers together with high-resolution climate model experiments, we show robust declining trends nu...
