An implementation of a particle system as part of the rendering pipeline of a 3-D computer game is described. Due to the interactive nature of such a computer game one of the most important issues in this implementation is the real-time rendering capability of the created special effects. A short summary of the game’s rendering pipeline is given, restrictions on special effects without a partic...

Self-report measures of adult attachment are typically scored in ways (e.g., averaging or summing items) that can lead to erroneous inferences about important theoretical issues, such as the degree of continuity in attachment security and the differential stability of insecure attachment patterns. To determine whether existing attachment scales suffer from scaling problems, the authors conducte...

When a data mining model is to be developed, one of the most important issues is preserving the privacy of the input data. In this paper, we address the problem of data transformation to preserve the privacy with regard to a data mining technique, associative classification, in an incremental-data scenario. We propose an incremental polynomialtime algorithm to transform the data to meet a priva...
