A frequency response based adaptive control scheme with robust frequency domain specifications for industrial center-driven web winders is presented in this paper. The adaptive control scheme consists of: 1) a self-tuning initialization, 2) an adaptive control, with robust specifications, based on the transfer function estimation from the frequency response, and 3) supervisory monitoring and co...

This paper studies so-called “null polynomials modulo m”, i.e., polynomials with integer coefficients that satisfy f(x) ≡ 0 (mod m) for any integer x. The study on null polynomials is helpful to reduce congruences of higher degrees modulo m and to enumerate equivalent polynomial functions modulo m, i.e., functions over Zm = {0, · · · , m − 1} generated by integer polynomials. The most well-know...

The main objective of this paper is to clarify the ontology of DiracHestenes spinor fields (DHSF ) and its relationship with even multivector fields, on a Riemann-Cartan spacetime (RCST) M =(M,g,∇, τg, ↑) admitting a spin structure, and to give a mathematically rigorous derivation of the so called Dirac-Hestenes equation (DHE ) in the case where M is a Lorentzian spacetime (the general case whe...

The effects of short-term administration of verapamil on left ventricular isovolumetric relaxation and early and late diastolic filling dynamics were studied in 10 patients with hypertrophic cardiomyopathy by a combined hemodynamic-ultrasonic technique. Left ventricular pressures (recorded with high-fidelity micromanometers) were determined simultaneously with M mode echocardiography. After 10 ...

A temporally resolved flow visualization system that produces 17 flow images over a time span of 128 microseconds is used to visualize the mixing layers of a Mach 1.28 (M c =0.59) and a Mach 2.06 (M c =0.87) ideally expanded high Reynolds number axisymmetric jets. These image sequences revealed details about the effects of compressibility on the dynamics of turbulence structures. In general, th...

The main objective of this paper is to clarify the ontology of DiracHestenes spinor fields (DHSF ) and its relationship with sum of even multivector fields, on a general Riemann-Cartan spacetime M=(M, g,∇, τg, ↑) admitting a spin structure and to give a mathematically rigorous derivation of the so called Dirac-Hestenes equation (DHE ) when M is a Lorentzian spacetime. To this aim we introduce t...

To validate the modified System for Observing Fitness Instruction Time to measure teacher practices related physical activity promotion (SOFIT+) in education (PE) amongst 5–6-year-old-children. Participants (n = 162, 53% female, 6.0 ± 0.3 yrs) were recruited from 9 schools. Video-recordings of 45 PE lessons teachers/coaches coded using a SOFIT+. Accelerometers measured children’s moderate-to-vi...

tial, as seen from an initial rapid rise of each slow PHI in Fig. 3, but the contamination is again small enough for the present purpose. The three sets of tracings in Fig. 3, B, show the result of simulation with the use of the circuit in Fig. 1, B, with three different values of time constant (4.5, 9, and 18 sec) and each rod potential in Fig. 3, A, used as an input. The tracings show that th...
