Eccentrically braced frames (EBFs) are typically employed in seismic design because they integrate the benefits of concentrically and moment-resisting frames, providing both high elastic stiffness ductility. However, effect fire on structural stability EBFs has not been well documented. Object-oriented techniques used software program development have become popular recent years, primarily thei...

We discuss some aspects of a recently proposed semi-classical transport theory for QCD plasmas based on coloured point particles. This includes the derivation of effective transport equations for mean fields and fluctuations which relies on the Gibbs ensemble average. Correlators of fluctuations are interpreted as collision integrals for the effective Boltzmann equation. The approach yields a r...

Introduction: Cassini radio science data indicates that Titan is nearly in hydrostatic equilibrium [1]. We have used thermal models [2] and hydrostatic equilibrium theory [3] to derive interior models of Titan. We show as the measurement of the principal quadrupole gravitational coefficient C22 from the Radio Doppler data from Cassini spacecraft will improve our knowledge of the interior struct...

Quantitative analysis of tracer data using moment analysis requires a strict adherence to a set of rules which include data normalization, correction for thermal decay, deconvolution, extrapolation, and integration. If done correctly, the method yields specific information on swept pore volume, flow geometry and fluid velocity, and an understanding of the nature of reservoir boundaries. All cal...

Research on the steel structures with confining of axial expansion in fixed beams has been quite intensive in the past decade. It is well established that the thermal behaviour has a key influence on steel structural behaviours. This paper describes mechanical behaviour of beams with bolted slant end-plate connection with nonsymmetric gravity load, subjected to temperature increase. Furthermore...

A statistical mechanical theory for heat flow is developed based upon the second entropy for dynamical transitions between energy moment macrostates. The thermal conductivity, as obtained from a Green-Kubo integral of a time correlation function, is derived as an approximation from these more fundamental theories, and its short-time dependence is explored. A new expression for the thermal condu...

The magnetization processes in binary magnetic/nonmagnetic amorphous alloy Hf57Fe43 are investigated by the detailed measurements including magnetic hysteresis loops, dependence of magnetic moment on temperature and relaxation of magnetic moment. The blocking of magnetization at lower temperatures is accompanied by the slow relaxation of magnetic moment and magnetic hysteresis loops. All of obs...

The electric dipole moments of (H2O)nDCl (n=3-9) clusters have been measured by the beam-deflection method. Reflecting the (dynamical) charge distribution within the system, the dipole moment contributes information about the microscopic structure of nanoscale solvation. The addition of a DCl molecule to a water cluster results in a strongly enhanced susceptibility. There is evidence for a noti...

A superparamagnetic nanoparticle (SPN) is a nanometre-sized piece of a material that would, in bulk, be a permanent magnet. In the SPN the individual atomic spins are aligned via Pauli effects into a single giant moment that has easy orientations set by shape or magnetocrystalline anisotropy. Above a size-dependent blocking temperature Tb(V, τobs) , thermal fluctuations destroy the average mome...

The objective of this paper is to seek an alternative to the numerical simulation of the Navier-Stokes equations by a method similar to solving the BGK-type modeled lattice Boltzmann equation. The proposed method is valid for both gas and liquid flows. A discrete flux scheme (DFS) is used to derive the governing equations for two distribution functions; one for mass and another for thermal ener...
