Controllability of convex processes [PDF]
1985 24th IEEE Conference on Decision and Control, 1985 The paper provides characterizations of controllability of the differential inclusion x'(t)\(\in A(x(t))\) where A is a convex process from \(R^ n\) into itself. As expected, controllability is equivalent to observability of the associated adjoint inclusion \(-q'(t)\in A^*(x(t))\) where \(A^*\) denotes the transpose of A.

Techniques for Tool Life Prediction and Autonomous Tool Change Using Real-time Process Monitoring Data [PDF]
한국정밀공학회지Materials such as titanium alloys, nickel alloys, and stainless steels are difficult to machine due to low thermal conductivity, work hardening, and built-up edge formation, which accelerate tool wear. Frequent tool changes are required, often relying on

CONTROLLING ACTIVATED PROCESSES [PDF]
Fluctuation and Noise Letters, 2001 The rates of activated processes, such as escape from a metastable state and nucleation, are exponentially sensitive to an externally applied field. We describe how this applies to modulation by high-frequency fields and illustrate it with experimental observations.

CONTROLLING OF THE LOGISTIC PROCESSES
Production Engineering Archives, 2014 The paper presents analysis of the controlling application in logistic processes in the foundry of the cast iron. Controlling of quality was introduced in order to raise efficiency of the foundry of the cast iron management. A comparative method was applied to examinations. Two spheres were compared to managing of the organization: managing the quality
