Developing real-life driving simulations for novice driver education
This paper will describe the technological aspects of producing live-action videos of real traffic scenarios for a new driver education training CD-ROM (CD DRIVES) aimed at novice drivers in New Zealand. CD-DRIVES was created in order to help young drivers practise crucial higher level driving skills such as eye scanning, hazard detection and risk management. We will present a roadmap of the technological advances made through hardware, software and processes used in the production and post-production stages of CD-DRIVES
A Computer-Based Interactive Multimedia Training CD-ROM for Novice Drivers in New Zealand
This paper will describe the psychological and educational rationales behind the development of a computer-based interactive multimedia training CD-ROM (âCD-DRIVESâ) that will be made available to all novice drivers in New Zealand at no cost to the individual. Novice drivers are lacking in crucial higher level driving skills such as eye scanning, hazard detection and risk management. More than 70 real-life traffic simulations allow these drivers to practice such skills from the safety of their own homes
Stable isotopic composition reveals the spatial and temporal dynamics of discharge in the large river of Yarlungzangbo in the Tibetan Plateau
Stable-isotope (H, O, and Si) evidence for seasonal variations in hydrology and Si cycling from modern waters in the Nile Basin:implications for interpreting the Quaternary record
Seasonal variations in hydrology and Si cycling in the Nile Basin were investigated using stable-isotope (H, O, and Si) compositions and dissolved Si (DSi) concentrations of surface waters, as a basis for interpreting lacustrine diatom sequences. delta O-18 ranged from -4.7 to +8.0 parts per thousand in the wet season and +0.6 to +8.8 parts per thousand. in the dry season (through 2009-2011). Higher delta O-18 values during the dry season reflected increased evapotranspiration and open water evaporation under conditions of lower humidity. Progressive downstream enrichment in the heavy isotope O-18 also occurred in response to cumulative evaporative losses from open water bodies and swamps. delta Si-30 values of DSi ranged from +0.48 to +3.45 parts per thousand. during the wet season and +1.54 to +4.66 parts per thousand during the dry season, increasing the previously reported global upper limit for delta Si-30 values in natural waters by 1 parts per thousand. Si-isotope fractionation was most intense during the thy season when demand for DSi by aquatic ecosystems exceeded supply. Progressive downstream enrichment in the heavy isotope Si-30, coupled with decreasing DSi concentrations, represented cumulative Si uptake by diatoms, macrophytes and other Si-accumulating aquatic organisms. The pronounced seasonal variations in DSi concentrations and Si-isotope compositions in the River Nile suggest that its DSi flux to the ocean may have varied significantly on a glacial/interglacial time scale, with important consequences for the marine Si budget and consequently the global C cycle. Anthropogenic impacts were evident in both the water- and Si-isotope datasets, especially during the dry season and along the Main Nile, where water management is most intensive.
