In this article, a novel globally exponentially convergent velocity observer for a class of mechanical systems with l nonholonomic constraints is presented. Through using a special coordinate transformation, the constrained system is converted into the integral cascade Euler–Lagrange form, which could avoid solving partial differential equations and eliminate the influence of the constraint force...
This paper describes a stream processing engine called S-Store and its role in the BigDAWG polystore. Fundamentally, S-Store acts as a frontend processor that accepts input from multiple sources, and massages it into a form that has eliminated errors (data cleaning) and translates that input into a form that can be efficiently ingested into BigDAWG. S-Store also acts as an intelligent router that...
