Some Consequences of a Well Known Theorem on Conics

Comparison of some well-known PID tuning formulas

Criteria based on disturbance rejection and system robustness are proposed to assess the performance of PID controllers. A simple robustness measure is defined and the integral gains of the PID controllers are shown to be a good measure for disturbance rejection. An analysis of some well-known PID tuning formulas reveals that the robustness measure should lie between 3 and 5 to have a good comp...

On Computing Gaussian Curvature of Some Well Known Distributions

The Gaussian curvature of the surface at the point p is the product of the maximum and minimum curvatures in the family. The objective of this paper is to provide a deeper and broader understanding of the meaning of Gaussian curvature, using some more general alternative computational methods. We define the coefficients of the expected Fisher Information Matrix as the coefficients of the first ...

Towards a Turkish-Armenian Rapprochement?

T urkish-Armenian relations have been deadlocked since Armenia gained its independence in 1991. The closed border and the lack of diplomatic ties cloud the future of bilateral relations as well as official and non-official efforts aimed at contributing to the process of normalization. However, Turkish-Armenian relations have been gaining momentum since 2002. The restoration of the Akhtamar Chur...
