Abstract:

«Dubaï Street», principale rue commerçante de Zanzibar, symbolise la pérennité historique des relations arabo-africaines. Les flux de biens et de personnes, fondés sur les réseaux familiaux, alimentent une économie parallèle qui échappe largement aux pouvoirs publics. Ceux-ci s’efforcent de contrôler les dynamiques socioculturelles, voire les turbulences politiques qui en résultent.

Ages of synrift igneous rocks, ranging from 765 to 530 Ma, document non-systematic diachroneity of rifting along the Iapetan margin. Synrift sedimentary accumulations show abrupt variations in thickness across transform faults, and some concentrations of synrift igneous rocks are distributed along transf

While a tremendous amount of work has been done on different plant species to highlight their metabolism during embryo development, a comprehensive analysis of metabolic flux in flax is still lacking.

We propose a way of unambiguously parallel transporting fields on non-Abelian flux tubes, or strings, by means of two gauge fields. One gauge field transports along the tube, while the other transports normal to the tube. Ambiguity is removed by imposing an integrability condition on the pair of fields. The construction leads to a gauge theory of mathematical objects known as Lie 2-groups, which are known to result also from the parallel transport of the flux tubes themselves. The integrability condition is also shown to be equivalent to the assumption that parallel transport along nearby stri

The relations of the net heat flux between two parallel plates with the material type were also discussed. The results demonstrate that the effect of surface polaritons is dominated in the spectral energy flux at 300 K when the distance is decreased to 100 nm. In addition, the intensity of surface polaritons increases with the temperature. The net heat flux between two parallel plates has a nearly linear relation with the temperature and is closely related

Abstract:

The detailed presentation of modern algorithm for the rotor speed estimation of an induction motor (IM) is shown. The algorithm includes parallel speed and resistance parameter estimation and allows a robust shaft-sensorless operation in diverse conditions, including full load and low speed operation with a large thermal drift. The direct connection between the injected electric signal in the d-axis and the component of injected rotor flux were pointed at. The algorithm that has been applied in the paper uses the extracted component of the injected rotor flux in the d-axis from the observer st

Abstract:

In this paper, the fault current limiting (FCL) characteristics of a flux-coupled type superconducting fault current limiter (SFCL) with parallel connection between two windings in a DC system were analyzed. The flux-coupled type SFCL was composed of two coils connected in parallel and a superconducting element (SE), which was connected in series with the secondary coil. The flux-coupled type SFCL works in DC systems similar to those in AC systems. Before a fault occurs, the respective magnetic fluxes generated by the two coils connected in parallel offset each other, maintaining the voltage i

Abstract:

The evolution of magnetic flux ropes in a sheared plasma flow is investigated. When the magnetic field outside the flux rope lies parallel to the axis of the flux rope, a flux rope of circular cross-section, whose centre is located at the midpoint of the shear layer, has its shape distorted, but remains in the shear layer. Small displacements of the flux-rope centre above or below the midpoint of the shear layer lead to the flux-rope being expelled from the shear layer. This motion arises because small asymmetries in the plasma pressure around the flux-rope boundary leads to a force that force

Abstract:

Abstract The magnetic flux loss due to the drift of plasma and magnetic field is investigated for gaseous layers with the magnetic field parallel to the layer surfaces. When the magnetic force is initially much stronger than gravity and the pressure of the external medium is negligible, a large drift velocity of ions is induced. However, because the cloud expands nearly freely, the magnetic flux loss is limited to the early phase of the expansion. Thus the flux loss by this mechanism seems insignificant in the situation realized in molecular clouds. The magnetic flux loss is also investigated

Abstract:

Variable property effects on vertical channel natural convection in air are studied systematically. Numerical solutions of the governing equations show that both the mass flow rate and heat transfer in the channel are not only lower than the constant property results, but also show a nonmonotonic variation with increasing wall temperature or wall heat flux. This phenomenon, which seemingly conflicts with the conventional knowledge, has also been identified by experiments. For a vertical channel with a uniform heat flux boundary condition, the wall may experience a sharp rise in temperature up

In this work of philosophical short story fiction, the billionaire Lathar Jackson visits Ethereon Flux to try out their groundbreaking technology, the ability to observe, and send paying customers to, better parallel universes of their lives. Every choice we make creates a parallel universe where that choice was made and, for the right amount of money, Ethereon Flux will allow you to see them, and move into the best one. However, when Lather is hooked up to the machines, they realize he isn’t generating parallel universes; in short, he

This paper presents the characteristic behavior of direct vector control of two induction motors with sensorless speed feedback having the same rating parameters, paralleled combination, and supplied from a single current-controlled pulse-width-modulated voltage-source inverter drive. Natural observer design technique is known for its simple construction, which estimates the speed and rotor fluxes. Load torque is estimated by load torque adaptation and the average rotor flux was maintained constant by rotor flux feedback control. The technique’s convergence rate is very fast and is robust to n

Using traditional theoretical imaging method, we predict invisible oscillations in the photodetachment cross section of [Formula: see text] near a thin soft surface. A laser which is polarized parallel to the surface is used to knock off electron from [Formula: see text]. Analytical expressions are derived for detached electron flux and photodetachment cross section. The results depend on the inter ion surface distance and separation of the atomic centers of the molecular anion. It is found that the surface strongly affects the detached electron flux and the photodetachment cross section. Unli

Abstract:

Trapping of flux line cores between weakly coupled superconducting layers is considered. An estimate of the resulting high intrinsic critical current is given for field and current both parallel to the layers. The first flux penetration is studied as a function of the field direction. Each flux line takes the shape of a Sine-Gordon soliton lattice and encounters a lock-in transition towards the layers at a critical orientation.

Abstract:

A review of recent results on nonlinear diffusion of magnetic flux in high-Tc superconductors is given. Making use of a universality of thermally-activated flux diffusion, one can formulate the problem of macroscopic flux dynamics in terms of directly measured quantities. A hierarchy of flux creep time-scales and their dependence on initial and boundary conditions is considered. The essential effect of the sample geometry on the flux creep dynamics is discussed for a thin plate in a parallel and perpendicular magnetic field, which corresponds to local and nonlocal regimes of nonlinear flux dif
