We model strong shock-wave propagation, both in the ideal gas and in the dense Lennard-Jones fluid, using a refinement of earlier work, which accounts for the cold compression in the early stages of the shock rise by a nonlinear, Burnett-like, strain-rate dependence of the thermal conductivity, and relaxation of kinetic-temperature components on the hot, compressed side of the shock front. The ...

Thermo-mechanical models are presented for predicting the time-to-failure of polymer laminates loaded in tension or compression and exposed to one-sided radiant heating by fire. Time-to-failure is defined as the time duration that a polymer laminate can support an externally applied load in a fire without failing. The models predict the temperature rise and through-thickness temperature profile...

Impurity transport has been investigated in the reactor-like conditions of the Alcator C-Mod divertor (divertor plasma density ≥1021 m-3, parallel heat flux in the SOL ≤0.5 GW-m-2). Trace amounts of the recycling impurity gases helium, neon, argon, and krypton were injected into plasmas. A residual gas analyzer that samples the private flux region of the divertor was used for divertor impurity ...

Introduction BNCT is an effective method to destroy brain tumoral cells while sparing the healthy tissues. The recommended flux for epithermal neutrons is 109 n/cm2s, which has the most effectiveness on deep-seated tumors. In this paper, it is indicated that using D-T neutron source and optimizing of Beam Shaping Assembly (BSA) leads to treating brain tumors in a reasonable time where all IAEA ...

Flux penetration into type-II superconducting films is simulated for transverse applied magnetic field and flux creep dynamics. The films contain macroscopic nonconducting holes, and we introduce the holes in the simulation formalism by reconstruction of the magnetic field change inside the holes. We find that the holes induce a region of reduced flux density extending toward the nearest sample...

In this paper, we propose a technique for coding the data from multiple correlated binary sources, with the aim of providing an alternative solution to the correlated source compression problem. Using non-systematic repeat-accumulate based codes, it is possible to achieve compression which is close to the Slepian–Wolf bound without relying on massive puncturing. With the technique proposed in t...

[1] Geosynchronous energetic particle fluxes are used to examine the differences and similarities between the particle disturbances due to an enhancement in solar wind dynamic pressure Pdyn and those caused by substorms. Disturbances are also distinguished by IMF conditions. First, for not strongly southward IMF conditions (weakly southward or northward IMF), we find that the magnetospheric com...

This paper presents the sizing of a Doubly Fed Induction Generator (DFIG) with power 690.747 kW for coastal area Benin. The proposed DFIG starts from density offshore wind potential Benin obtained at 80 m sea surface to determine generator. Thanks geometrical, electrical and magnetic parameters after sizing, simulation generator operation was done using finite element analysis (FEA). is by runn...

The aim of this paper is to analyze how a permanent magnet linear generator for wave power behaves when the stator slots are closed. The usual design of stator geometry is to use open slots to maintain a low magnetic leakage flux between the stator teeth. By doing this, harmonics are induced in the magnetic flux density in the air-gap due to slotting. The closed slots are designed to cause satu...
