Abstract We present the first examples of phase transitions in asymptotically flat black hole solutions. analyse thermodynamic properties holes order N ⩾ 3 Lovelock gravity, with zero cosmological constant. fin...

an s-curve to describe the gradual transition between exhaust pressure and intake or inlet pressure. The start of compression, which marks the end of the intake process, does not necessarily occur at the same time as the close of the intake valve (IVC). The intake valve closes after bottom center (BC) while the volume in the cylinder is decreasing. The engine speed determines the point at which...

Generalized Constant Propagation (GCP) statically estimates the ranges of variables throughout a program. GCP is a top-down compositional compiler analysis in the style of abstract intepretation. In this paper we present an implementation of both intraprocedural and interprocedural GCP within the context of the C language. We compare the accuracy and utility of GCP information for several versi...

We present new static spherically-symmetric exact solutions of Einstein equations with the quintessential matter surrounding a black hole charged or not as well as for the case without the black hole. A condition of additivity and linearity in the energy-momentum tensor is introduced, which allows one to get correct limits to the known solutions for the electromagnetic static field implying the...

In the present paper, natural convection fluid flow and heat transfer in a square cavity heated from below and cooled from sides and the ceiling with a thin fin attached to its hot bottom wall is investigated numerically. The right and the left walls of the cavity, as well as its horizontal top wall are maintained at a constant temperature Tc, while the bottom wall is kept at a constant tempera...

A recently proposed method for computer simulations in the isothermal– isobaric (NPT) ensemble, based on Langevin–type equations of motion for the particle coordinates and the “piston” degree of freedom, is re–derived by straightforward application of the standard Kramers–Moyal formalism. An integration scheme is developed which reduces to a time–reversible symplectic integrator in the limit of...

Abstract In this paper, the Joule-Thomson expansion of Born-Infeld AdS black holes is studied in extended phase space, where cosmological constant identified with pressure. The coefficient, inversion curves and isenthalpic are discussed detail using a 4-dimensional hole. critical point hole depicted varying parameter charge Q . T-P plane, temperature obtained different We fi...

Article history: Received: 18.6.2015. Received in revised form: 29.11.2015. Accepted: 1.12.2015. Dynamic damage evolution during coal seam pulse water infusion is simulated through secondary development of ABAQUS software in this paper in order to obtain the rule of dynamic damage evolution of coal seam around the pulse water infusion hole. It provides a new quantitative method of determining c...
