Dynamic modelling of hardness changes of aluminium nanostructure during mechanical ball milling process

In this research, the feasibility of using mathematical modelling in the ball milling process has been evaluated to verify the hardness changes of an aluminium nanostructure. Considering the model of normal force displacement (NFD), the radius of elastic-plastic and normal displacement of two balls were computed by applying analytical modelling and coding in MATLAB. Properties of balls and alum...

Injection drug use among street youth: a dynamic process.

sectional anonymous study to estimate HIV prevalence and associated risk factors among street youth in Montréal. A total of 919 participants aged 13 to 25 years were recruited with the collaboration of 20 street youth agencies. An HIV prevalence rate of 1.85% (95% CI 1.12-2.89) was found, which was 3.7 times higher than the rate estimated for the general Montréal population. Injection drug use ...

A SPICE MODEL FOR IGBTs

Figure 1. Basic IGBT subcircuit Introduction You’ve finally tested a version of your design that seems to work well, but you would feel a lot better if you KNEW the circuit would work well with all the devices that the vendor will supply in production. You found a model in a library, but you are not sure what specifications from the data book apply to that model. The following paragraphs will t...
