3-d Immersive Screen Experiments
We are currently piloting a range of computer simulated science experiments as 3-D virtual environments. These are rendered on a PC in 3-D and use photographs of specific parts of the actual apparatus as textures to add realism to the simulation. In particular, photographs are used to represent the consequential views of an experiment. These particular views may also be animated depending on th...
متن کاملInteractive screen experiments - innovative virtual laboratories for distance learners
The desirability and value of laboratory work for physics students is a wellestablished principle and issues arise where students are inherently remote from their host institution, as is the case for the UK's Open University. In this paper, we present developments from the Physics Innovations Centre for Excellence in Teaching and Learning (piCETL) in the production and technology of the virtual...
متن کاملStatistically designed experiments to screen chemical mixtures for possible interactions.
For the accurate analysis of possible interactive effects of chemicals in a defined mixture, statistical designs are necessary to develop clear and manageable experiments. For instance, factorial designs have been successfully used to detect two-factor interactions. Particularly useful for this purpose are fractionated factorial designs, requiring only a fraction of all possible combinations of...
متن کاملPost-editing on-screen: machine translation from Spanish to English
The end of 1986 marked seven years of ongoing machine translation (MT) production at the Pan American Health Organization (PAHO) in the Spanish-English combination. SPANAM, the Spanish-English MT software developed in-house, and its newer English-Spanish partner ENGSPAN (Vasconcellos and León 1985), are free-syntax ‘try-anything’ systems (Lawson, 1982) designed to be challenged by many types of...
متن کاملAdjusting Treatment Effect Estimates by Post-Stratification in Randomized Experiments∗
Experimenters often use post-stratification to adjust estimates. Post-stratification is akin to blocking, except that the number of treated units in each stratum is a random variable because stratification occurs after treatment assignment. We analyze both post-stratification and blocking under the Neyman-Rubin model and compare the efficiency of these designs. We derive the variances for a pos...
