The concept of majorisation is explored as a tool to characterize the performance quantum Otto engine in quasi-static regime. For working substance form spin arbitrary magnitude, yields necessary and sufficient condition for operation engine, provided canonical distribution medium at hot reservoir majorised by its cold reservoir. case spin-1/2 interacting with an via isotropic Heisenberg exchan...

the mechanical aspect of entropy-exergy relationship, together with the thermal aspect usually consid-ered, leads to an extended formulation of physical exergy based on both maximum useful work and maximum useful heat that are the outcome of available energy of a thermodynamic system. this approach suggests that a mechanical entropy can be studied, in addition to the already used thermal entrop...

– We analyze the effect of a quantum error correcting code on the entanglement of encoded logical qubits in the presence of a dephasing interaction with a correlated environment. Such correlated reservoir introduces entanglement between physical qubits. We show that for short times the quantum error correction interprets such entanglement as errors and suppresses it. However for longer time, al...

The paper deals with the reliability–based design optimization (RBDO) of concrete gravity dams subjected to earthquake load using subset simulation. The optimization problem is formulated such that the optimal shape of concrete gravity dam described by a number of variables is found by minimizing the total cost of concrete gravity dam for the given target reliability. In order to achieve this p...

The probability distribution of a function subsystem conditioned on the value whole, in limit when ratio their values goes to zero, has law: It equals unconditioned marginal weighted by an exponential factor whose exponent is uniquely determined condition. We apply this theorem explain canonical equilibrium ensemble system contact with heat reservoir. Since only requires analysis at level and r...

Our understanding of the processes underlying the formation of heavy oil has been transformed in the last decade. The process was once thought to be driven by oxygen delivered to deep petroleum reservoirs by meteoric water. This paradigm has been replaced by a view that the process is anaerobic and frequently associated with methanogenic hydrocarbon degradation. The thermal history of a reservo...

abstract: This work aims to verify the influence of foundation and reservoir on dynamic behavior concrete gravity dams in terms natural frequencies, vibration modes for a free analysis; maximum displacements stresses at singular points structure seismic excitation. The dam-reservoir-foundation interaction was investigated through modal transient analysis by finite element method via ANSYS APDL ...

We investigate the dynamical evolution of genuine multipartite correlations for N-qubits in a common reservoir considering non-dissipative qubits-reservoir model. derive an exact expression time-evolved density matrix by modeling as set infinite harmonic oscillators with bilinear form interaction Hamiltonian. Interestingly, we find that choice two-level systems corresponding to initially correl...

The Berriasian-Valanginian Fahliyan Formation forms one of the giant reservoirs in the subsurface of the Abadan plain, onshore Iran. A detailed petrographical analysis of the available cores and thin sections revealed that the different diagenetic parameters influenced the reservoir quality of the Fahliyan Formation in this field. The Fahliyan Formation has been influenced by three diagenetic e...
