This paper introduces the PS3 R © Grid-resource model, which allows any Internet connected Playstation 3 to become a Grid Node without any software installation. The PS3 R © is an interesting Grid resource as each of the over 5 millions sold world wide contains a powerful heterogeneous multi core vector processor well suited for scientific computing. The PS3 R © Grid node provides a native Linu...

This paper examines R&D tax incentives in oligopolistic markets. It is generally agreed that R&D has some characteristics of a public good. Therefore, the market will fail to provide a sufficient amount of R&D. A tax incentive for R&D can be implemented by the government to fix this market failure. However, the controversy over the effectiveness of R&D tax incentives is still considerable. In t...

Our algorithm simplifies vertex connectivity using the clustering techniques described in [3]. Unlike [3], it does not evenly voxelize the model; instead simplification varies with curvature. The algorithm begins with the entire model contained within a single cell. This cell is subdivided based on the curvature within the cell. From the cells that result, the cell with the most curvature is se...

The ACT-R computational modeling architecture has demonstrated the ability to model both recency and frequency effects in memory with much success (e.g. Anderon & Lebiere, 1998); and through the incorporation of new decay parameters at each data point, has also been shown to capture the spacing effect (Pavlik & Anderson, 2003, 2005). Stemming from the aforementioned literature, the current rese...

Function lmodel2 computes model II simple linear regression using the following methods: major axis (MA), standard major axis (SMA), ordinary least squares (OLS), and ranged major axis (RMA). Information about these methods is available, for instance, in section 10.3.2 of Legendre and Legendre (1998) and in sections 14.13 and 15.7 of Sokal and Rohlf (1995). Parametric 95% confidence intervals a...
