Some Experiments on the Welding Speed

Some Randomness Experiments on TRIVIUM

This paper develops two methods for exploring the structure of the stream cipher TRIVIUM. We consider whether it is possible to compute the algebraic normal form (ANF) of such functions. Since the key and the IV together make up 160 variables, doing this directly is not possible. Instead, one can choose a subset of the key and IV variables of size n and fix the other variables to constants. As ...

The effect of tool transverse speed on the properties of aluminum-steel dissimilar joint by friction stir welding

This present study aimed to create an Al6061-St52 dissimilar joint and investigate the effect of the transverse speed by the friction stir welding process. Welding aluminum to steel is rugged by fusion methods because of the formation of brittle intermetallic compounds (IMCs). Therefore, to designate optimal parameters, acceptable IMC thickness, and mechanical properties determined. This resear...

Designing experiments to study welding processes: using the Taguchi method

Identification of significant process parameters using experiments needs to be carefully formulated as it can be a resource demanding process. Using appropriate statistical techniques such as the Taguchi method of factorial design of experiments, the number of necessary experiments can be reduced and the statistical significance of parameters can be safely identified. In the case of linear fric...
