Adaptive algorithms lead to adjust the system coefficients based on the measured data. This paper presents a dichotomous coordinate descent method to reduce the computational complexity and to improve the tracking ability based on the variable forgetting factor when there are a lot of changes in the system. Vedic mathematics is used to implement the multiplier and the divider in the VFF equatio...

The work that I'm going to describe was funded by the Air Force Materials Lab from February 1972 to February 1974. It is described in an AFML report, TR74-80, available from the Air Force. This report describes a more practical type of problem than has been discussed so far. Our work was directed towards building an ultrasonic system to be used on aircraft in the field to detect cracks around f...

1]. The latter appears to be the central issue raised by P. Degens and R. Merget with regard to the article [1]. The authors state that it is not necessary to move on with the European project as updated equation references already exist [2]. This is where we are compelled to disagree. Apart from the fact that the Swiss Cohort Study on Air Pollution and Lung Diseases in Adults (SAPALDIA) was ci...
