A dozen people who cannot speak and have very limited voluntary muscle control because of cerebral palsy or traumatic brain injury have tried using a new technology called the Camera Mouse to access the computer. Nine of the people were successful, in many cases being able to spell words or run commercial software or access the internet for the first time. The Camera Mouse is non-invasive and u...

In this paper, we demonstrate that many hypothesis testing problems in clinical pharmacology studies can be reformulated as a oneor two-sample t-test or equivalence test. Thereby one can use SAS® Proc Power to perform the power analysis. Sample programs for different hypothesis testing problems are presented in a variety of study design settings. Compared to other commercial software such as NQ...

Abstract— Forging is a very complex process and the measurement of actual forces for real material is difficult and cumbersome. The main objective of this document is to use the analytical methods for measuring parameters such as load, and stress distribution of forging process and use them to make simple, reliable, fast and non-expensive simulation tools, contrary to the commercial software’s ...

We study the behaviour of an algorithm which compresses relational tables by representing common subspaces as Cartesian products. The output produced allows space to be saved while preserving the functionality of many relational operations such as select, project and join. We describe an implementation of an existing algorithm, propose a slight modification which with high probability produces ...

For years, one of the main reasons to buy commercial software instead of adopting open-source applications was the, supposed, guarantee of quality. Unfortunately that was rarely true and, fortunately, open-source projects soon adopted some good practices in their code development that lead to better tested software and therefore higher quality products. In this article we provide a guided tour ...

This paper proposes a specific set of criteria for evaluating discrete-event Simulation Software capable of simulating continuous operations. A quality specifications model was developed; it identified 40 sub-characteristics and 131 metrics to assess the quality of this type of software; it is then to be used in the selection process. The application was demonstrated in one organization that pr...

Testing for Listeria is challenging because of its slow growth rate. Recently, we described a rapid Listeria culture isolation method. This method can be improved by utilizing a rapid molecular detection test such as the Assurance GDS tests for Listeria and Listeria monocytogenes. These two methods (culture isolation and Assurance GDS) use different enrichment strategies that may affect the num...

Caterpillar has been collaborating with suppliers to analyze steel castings for the tendency to form hot tears using a newly developed damage-based model. The implementation and application of the damage-based hot tear model is presented. The implementation is through an uncoupled simulation of the solidification and deformation problems using commercial software with a user-defined constitutiv...

The previous study by thefor the finite element analysis of superelastic, large deformation behaviors of one-dimensional shape memory alloy (SMA) devices is extended to the magneto-superelastic analysis of ferromagnetic shape memory alloy (FSMA) devices. The commercial code ANSYS/ Emag for magnetic analysis is combined with the SMA superelastic analysis program developed by the authors. The num...

Considering how popular grapes are in terms of their antioxidant benefits, we compared concord, purple, red, and green grapes for total antioxidant capacity (TAC) and carbohydrate concentration. All grapes were acquired from commercial sources and samples of each were separated into skinned and not skinned groups. Each whole grape and the skins were individually homogenized and then separated i...
