What is the Pi theorem?
The Pi theorem gives you a procedure to determine the dimensionless groups. So much work has come out of using non dimensional analysis. If you want refer to G.I.Barenblatt (Scaling, Self-similarity, and Intermediate Asymptotics) book or another classic from an application point of view is Sedov (Similarity and Dimensional methods in mechanics).
What is Lami's theorem?
Lami's Theorem is applied in a static analysis of structural and mechanical systems. Lami's Theorem is named after Bernard Lamy. Lami 's Theorem states, "When 3 forces related to the vector magnitude acting at the point of equilibrium, each force of the system is always proportional to the sine of the angle that lies between the other two forces."
How can I prove that I have connectivity from the lambda function?
I can prove that I have connectivity from the lambda function to the internet by setting up a Socket connection e.g. Socket s = new Socket(InetAddress.getByName("bbc.co.uk"), 80);and I can retrieve data this way.
What is Pi Lambda Phi?
The Pi chapter of the national fraternity Pi Lambda Phi was established at Dartmouth College in 1924. The membership of the Dartmouth chapter was predominantly Jewish.
