Abstract This research is stressed at time and space characteristics (centre of gravity movements) in female pole vault. There are involved 19 vault jumpers with sport performance 380 – 483 cm, divided on 2 different groups; higher lower level from the point performance. We found that parameters reached better results high phases hanging lifting. It coursed by transmission after take-off work p...

Because of extreme local saturation at pole tips of excited phase and uncircular shape of rotor and stator, a Swithed Reluctance Motor (SRM) does not have a simple and accurate mathematical model. Therefore, the output control of this motor requires a robust controller which is not based on an accurate model of the process. Fuzzy controllers, to some extent, will satisfy these requirements. Tet...

After a review of the canonical reduction to the rest-frame Wigner-covariant instant form of standard theories in Minkowski spacetime, a new formulation of tetrad gravity is introduced. Its canonical reduction, also in presence of N scalar particles, is done. The modification of the ADM formulation to solve the deparametrization problem of general relativity (how to recover the rest-frame insta...

In the framework of dimensional regularization, we propose a generalization renormalization group equations in case perturbative quantum gravity that involves metric and higher order Riemann curvature couplings. The zero cosmological constant is considered. Solving (RG) compute respective beta functions derive recurrence relations, valid at any Newton constant, relate pole terms 1 / ( d ? 4 ) n...

If the standard model is embedded in a conformal theory, what is the simplest possibility? We analyse all abelian orbifolds for discrete symmetry Zp with p ≤ 7, and find that the simplest such theory is indeed SU(3)7. Such a theory predicts the correct electroweak unification (sin2θ ≃ 0.231). A color coupling αC(M) ≃ 0.07 suggests a conformal scale M near to 10 TeV. Permanent address. e-mail: f...

Efflux time measurements are carried out for gravity draining of a liquid from a large cylindrical tank (where the flow is essentially laminar) through single exit pipe in the absence and presence of Cetyl Pyridinium Chloride (CPC) surfactant solutions. The variables considered are initial height of liquid in the tank, dia. of tank, length of the exit pipe and concentration of surfactant. T...
