Résumé :

ABSTRACT The highly tangled magnetic field of a magnetar supports shear waves similar to Alfvén waves in an ordered magnetic field. Here, we explore if torsional modes excited in the stellar interior and magnetosphere can explain the quasi-periodic oscillations (QPOs) observed in the tail of the giant flare of SGR 1900+14. We solve the initial value problem for a tangled magnetic field that couples interior shear waves to relativistic Alfvén shear waves in the magnetosphere. Assuming stellar oscillations arise from the sudden release of magnetic energy, we obtain constraints on the energetics

Résumé :

Abstract Many regions of the universe are in a state of hot, magnetized, and ionized X-ray emitting plasmas. We numerically simulated the energy spectrum of this highly viscous and conductive system. Without magnetic field, the fluctuating plasma motion decays in a relatively large viscous scale l ν (∼1/k ν ). However, the magnetic field extends the viscous scale to the magnetic diffusivity one l η (∼1/k η ) yielding a unique energy spectrum. Numerical simulation shows that kinetic and magnetic energy spectrum are E V ∼ k −3.7 and E M ∼ k −0.85 in the extended viscous scale regime. To explain

Résumé :

The field of power and energy engineering in Jordan went through a period of decline during the period between 1990 and 2000, which resulted in students of electrical engineering pursuing other fields such as communications and computing, as the advances in the technologies of cellular communications and computer networking created more opportunities for recent graduates, and provided an attractive field of study for the students at that time.

Résumé :

With the rapid development of sixth-generation (6G) wireless networks and large-scale multiple-input multiple-output (MIMO) technology, the number of antennas deployed at base stations (BSs) has increased significantly, resulting in a high probability that users are in the near-field region. Note that it is difficult for the traditional far-field plane-wave model to meet the demand for high-precision beamforming in the near-field region. In this paper, we jointly optimize the power and the number of antennas to achieve the maximum energy efficiency for the users located in the near-field regio

Résumé :

Unified field theory is the long-sought means of tying together all known phenomena to explain the nature and behaviour of all matter and energy in existence. The quest for unification has been the perennial theme of modern physics. The belief that all physical phenomena can be reduced to simple and explained by a smaller number of laws is the central tenet of physics. Such a theory could potentially unlock all the secrets of nature and make a myriad of wonders possible, including such benefits as time travel and an inexhaustible source of clean energy, among many others.

Résumé :

Making use of the thermo field dynamics (TFD) we formulate a calculable method for time-dependent nonequilibrium systems in a time representation (t-representation) rather than in the k0-Fourier representation. The corrected one-body propagator in the t-representation has the form of B−1 (diagonal matrix) B (B being a thermal Bogoliubov matrix). The number parameter in B here is the observed number (the Heisenberg number) with a fluctuation. With the usual definition of the on-shell self-energy a self-consistent renormalization condition leads to a kinetic equation for the number parameter. Th

In this paper, we address some of the issues raised in the literature about the conflict between a large vacuum energy density, a priori predicted by quantum field theory, and the observed dark energy which must be the energy of vacuum or include it. We present a number of arguments against this claim and in favor of a null vacuum energy. They are based on the following arguments: A new definition for the vacuum in quantum field theory as a frame-independent coherent state; results from a detailed study of condensation of scalar fields in Friedmann–Lemaître–Robertson–Walker (FLRW) background p

Edge weight-based segmentation methods, such as normalized cut or minimum cut, require a partition number specification for their energy formulation.

However, finding a suitable partition number is a nontrivial problem, and the numbers are ordinarily manually assigned. This is an aspect of the general partition problem, where finding the partition number is an important and difficult issue.

Introduced as a quantum extension of Maxwell's classical theory, quantum electrodynamic (QED) has been the first example of a quantum field theory (QFT).

More surprisingly, it has also provided a framework for the understanding of second order phase transitions in statistical mechanics. In fact, as hopefully this work illustrates, QFT is the natural framework for the discussion of most systems involving an infinite number of degrees of freedom with loc

This essay explores the paradox of how a religion as ethical as Buddhism appears to have no ethics, or at least to lack the philosophical discipline that normally goes by that name. Buddhism is rightly admired for its moral teachings, but the tradition itself has shown a curious lack of interest in critical reflection on those teachings. Ethical dilemmas are rarely explored, and discussion of meta-ethical issues is almost entirely lacking. Instead Buddhist intellectual energy appears to have been channeled predominantly into metaphysics and certain related fields like logic and epistemology. N

Once the coupling to a large environment is switched on, the system dissipates its energy continuously to the environment until it reaches equilibrium with the latter.

Dynamo action creates a strong magnetic field with a complex structure, which becomes dominantly dipolar when solar activity is low. The state of solar activity varies in an 11-year cycle, which is evident in the number of sunspots on its surface. The Sun’s outermost layer, or corona, is a hot

Résumé :

The application of laser pulses with supershort duration of the order of 10 fs has recently been proposed [1,2] for enhancement of high order harmonic emission and subfemtosecond pulse production in the soft X-ray range. Such short driving pulses contain only a small number of optical cycles and therefore high energy photon bursts are generated due to atom ionization at rapidly increasing field amplitudes. It is obvious that the efficiency of this process becomes dependent on the concrete field distribution over the pulse or, in the other words, on the absolute phase of the optical field.

Résumé :

The increasing demand for more efficient energy conversion is making it extremely difficult for designers to develop next generation of centrifugal compressors. As the Reynolds number in centrifugal compressor operation decreases with increasing flight altitude, the efficiency degradation associated with it has been a key limitation to the energy conversion efficiency of aircraft engines. In this paper, the performance and internal flow field of a centrifugal compressor for a rear stage of a combined compressor are numerically simulated under different inlet conditions.

The use of synchrotron radiation has reached a quite mature stage all over the world with dedicated electron storage rings equipped with a large number of beam lines to accommodate an even larger number of simultaneous experiments. The spectrum of the light which depends upon the energy of the accelerated particles covers continuously the electromagnetic spectrum from the infra-red to the ultra-violet up to the soft X-ray and hard X-ray range. The main characteristics are the high flux or mean power, the high brillance, the small divergence, an access to linear and circular polarization, the h

Résumé :

Natural-convection flow in the presence of a magnetic field in an enclosure heated from bottom and cooled from top is considered. The fluid (molten sodium) properties are function of temperature. To solve the governing non-linear differential equations (mass, momentum and energy) a finite volume code based on PATANKAR’s SIMPLER method is utilized. The results for different Rayleigh and Hartmann numbers show that the strength of the magnetic field has significant effects on the flow and temperature fields. The convection becomes stronger as the Rayleigh number increases while the magnetic field

In this work, entropy generation due to laminar viscous incompressible flow of a conducting fluid in the presence of a transverse magnetic field in a porous inclined channel is investigated. Fully developed flow field is solved analytically whereas the solution of the energy equation is obtained by Finite Difference Method (FDM). The boundary conditions at the walls are considered to be constant heat flux. The influence of the applied magnetic field, porous medium and the viscous dissipation on velocity, temperature and entropy generation is examined. The dependence of flow and thermal charact

Résumé :

Evaluating the seismic performance of concrete dams requires nonlinear dynamic analysis of two- or three-dimensional dam–water–foundation rock systems that include all the factors known to be significant in the earthquake response of dams. Such analyses are greatly complicated by interaction between the structure, the impounded reservoir and the deformable foundation rock that supports it, and the fact that the fluid and foundation domains extend to large distances. Presented in this report is the development of a direct finite-element (FE) method for nonlinear earthquake analysis of two- and

This paper serves as explanatory notes to the development of a text for a climate treaty to tax carbon on a global basis – a Multilateral Carbon Tax Treaty (MCTT). Several leading practitioners and academics in their respective fields provided inputs to drafting the MCTT. The MCTT comes at a crucial point in history. There are recurrent requests to establish a global taxation regime, or a cooperative solution, to transition away from fossil fuels as the main source of energy supply. The momentum for change comes from: (a) a growing number of initiatives from countries with a history of further
