The use of fancy graphics can have a mesmerizing effect on simulation novices and, as such, may blind the user to the actual capabilities and valid usages. The visualization of simulations are distinct from other computer graphic media because they are a representation of an abstract of reality (the model) as opposed to a representation of reality. This extended abstract provides examples of vi...

This is a “cheat sheet”, which means that it consists of information packaged in a concise and efficient way so that it can easily be used as a quick reference. The topic is ranks of elliptic curves, mostly over Q. This is a slightly revised version of the handout I wrote as a supplement to my survey talk “Distributions of Ranks of Elliptic Curves” at MSRI’s Connections for Women: Arithmetic St...

This study enhances the strength of Al6061 alloy by adding Ti in form a rod using thermomechanical process, which would be useful making structures for aerospace and structural members. Two different properties material are joined together to new bimetallic material. Softer Al-6061 is used as sleeve, grade-II core. They were prepared with co-extrusion process at temperature 400 °C ratios 2:1 2:...
