Phase change materials are substances that absorb and release thermal energy during the process of melting and freezing. This characteristic makes phase change material (PCM)  a favourite choice to integrate it in buildings. Stephan problem including melting and solidification in PMC materials is an practical problem in many engineering processes. The position of the moving boundary, its veloci...

Abstract It is generally understood that a given one-dimensional diffusion may be transformed by Cameron–Martin–Girsanov measure change into another with the same volatility but different drift. But to achieve this, we have know change-of-measure local martingale write down true martingale. We provide complete characterisation of when this happens. This enables us discuss absence arbitrage in g...

Global large-scale urbanization and climate change have become indisputable scientific facts yet are unresolved issues, a common concern for mankind. The relationship between these two topics is unclear it not known how to deal appropriately at the level with in process of urbanization. Further exploration science, management practice, needed achieve global regional sustainable development. Thi...

In present paper acombination of three-dimensional isothermal and two-dimensional non-isothermal Lattice Boltzmann Method have been used to simulate the motion of bubble and effect of wetting properties of the surface on bubble separation. By combining these models, three-dimensional model has been used in two-dimension for decreasing the computational cost. Firstly, it has been ensured that th...

Design and maintenance of data warehouses has become an important research topic. In parallel to this, the topic of temporal databases is also an active area of research. This article covers the application of temporal ideas to data warehouse design. First, we present the notion of a data warehouse in general and describe the most approved method of structuring data in data warehouses, namely s...

In (2+1)-dimensional general relativity, the path integral for a manifold M can be expressed in terms of a topological invariant, the Ray-Singer torsion of a flat bundle over M . For some manifolds, this makes an explicit computation of transition amplitudes possible. In this paper, we evaluate the amplitude for a simple topology-changing process. We show that certain amplitudes for spatial top...

In this paper I compare two different the models of two-dimensional belief change, namely ‘revision by comparison’ (Fermé and Rott, Artificial Intelligence 157, 2004) and ‘bounded revision’ (Rott, in Hommage à Wlodek, Uppsala 2007). These revision operations are two-dimensional in the sense that they take as arguments pairs consisting of an input sentence and a reference sentence. Two-dimension...

We investigate topology change in (1+1) dimensions by analyzing the scalarcurvature action 12 ∫ RdV at the points of metric-degeneration that (with minor exceptions) any nontrivial Lorentzian cobordism necessarily possesses. In two dimensions any cobordism can be built up as a combination of only two elementary types, the “yarmulke” and the “trousers.” For each of these elementary cobordisms, w...
