(By measurement we mean all variables of a theoretical relation that determine the length have been quantitatively observed, no ROMs.) The skew above the electron skin depth of the scale length population determined an average scale length of the ‘‘EDRs’’ 80% higher than the upper bound stated in the ‘‘EDR’’ study’s abstract. This situation contributes another average multiplicative enhancement...

The shape features of planar trigonometric Bézier curves with two shape parameters are analyzed. The necessary and sufficient conditions are derived for these curves having one or two inflection points, a loop or a cusp, or be locally or globally convex. All conditions are completely characterized by the relative position of the control polygon’s side vectors. Furthermore we discussed the influ...

In this thesis, I study optical pumping as a powerful cooling tool for trapped ultra-cold atoms in a highly collisional regime. First application of optical pumping is a continuous loading scheme used to transfer atoms from a guided beam into a hybrid trap. Further, I introduce a Sisyphus cooling scheme based on radio-frequency transitions and optical pumping, operating simultaneously to the ac...

In the natural case of an hypervelocity impact on a planetary or asteroidal surface, two competing phenomena occur: partial or complete shock demagnetizat on of preexisting remanence and acquisition of shock remanent magnetization (SRM). In this paper, to better understand the effects of shock on the magnetic history of rocks, we simulate this natural case through laser shock experiments in con...

It is experimentally demonstrated that an adiabatic demagnetization-remagnetization in the laboratory frame, where the Zeeman order of abundant nuclei is first adiabatically converted into the dipolar order, and then, into the Zeeman order of rare nuclei, can significantly increase polarization of rare nuclei compared to the conventional cross-polarization technique.

The lowest temperatures ever measured have been produced by cascade adiabatic nuclear demagnetization of copper and rhodium. Ultimately, spontaneous antiferromagnetic ordering of rhodium nuclei is anticipated. High-sensitivity SQUID-NMR measurements at high nuclear polarization in low magnetic "elds have been used to study the mutual interactions between the nuclear spins of rhodium in the meta...

An algorithm was developed detect the partial demagnetization of permanent-magnet synchronous motors (PMSMs) under both stationary and nonstationary conditions. On basis recursive least-squares (RLS) method, vital component fault-related harmonics in current could be extracted on line, its proportion to fundamental regarded as indicator faults. The proposed is fairly easy realize substitute con...

The current morphology of the Martian lithospheric magnetic field results from magnetization and demagnetization processes, both of which shaped the planet. The largest Martian impact craters, Hellas, Argyre, Isidis and Utopia, are not associated with intense magnetic fields at spacecraft altitude. This is usually interpreted as locally nonor de-magnetized areas, as large impactors may have res...

Numerical studies support the conjecture that in continuum planar QCD the eigenvalue density of a Wilson loop operator undergoes a transition as the loop is dilated while keeping the loop shape fixed. A second part of the conjecture is that the transition obeys large N universality and that this universality class is the same in 2, 3 and 4 Euclidean space-time dimensions. The focus of the talk ...
