Abstract—This study presents a simple inverse heat transfer procedure for predicting the wall erosion and the time-varying thickness of the protective bank that covers the inside surface of the refractory brick wall of a melting furnace. The direct problem is solved by using the Finite-Volume model. The melting/solidification process is modeled using the enthalpy method. The inverse procedure r...

We compute the entropy of systems of quantum particles satisfying the fractional exclusion statistics in the space-time of 2+1 dimensional black hole by using the brick-wall method. We show that the entropy of each effective quantum field theory with a Planck scale ultraviolet cutoff obeys the area law, irrespective of the angular momentum of the black hole and the statistics interpolating betw...

One of the niftiest things about quantum mechanics is that it allows, via quantum tunneling (described in the Quantum Notes and in the lecture), many seemingly impossible events to occur, like walking through a brick wall, surviving after getting shot in the face, and meeting the girl of your dreams. Continuing on the theme of “possibility,” these notes describe parallel universes, in which eve...

In this paper we investigate statistics entropy of a 3-dimensional rotating acoustic black hole based on generalized uncertainty principle. In our results we obtain an area entropy and a correction term associated with the noncommutative acoustic black hole when λ introduced in the generalized uncertainty principle takes a specific value. However, in this method, is not need to introduce the ul...

Humidity is an indoor environmental factor that can affect thermal comfort inside a building. Sustainable construction techniques to create and maintain healthy indoor condition, based on ecological principles and through an efficient use of resources are the requirement nowadays. Common cause of moisture during the hot season is excessive indoor humidity, caused by an improper balance between ...

We define an arc-coloring for directed hypergraphs, such that any two arcs having either intersecting tails or the same head must be colored differently. We investigate the arc-coloring of those hypergraphs which can be represented by suitable adjacency matrices (walls), whereas a polynomial reduction is provided from the general arc-coloring problem to the brick-coloring of walls. An upper bou...

When testing multi-storey structures, most testing facilities require the testing of a reduced-scale model. A literature review on tests of scaled masonry structural components revealed that scaling of masonry was rather challenging and often significant differences in stiffness, strength and failure mechanisms between the different sized masonry were reported. This paper addresses the scaling ...

In this study, mold and moisture risk of external walls were investigated based on the six different wall types (block bims 1-2-3-4, hollow brick, aerated concrete) three insulation materials (hemp wool, aerogel blanket, extruded polystyrene). During examinations, uninsulated insulated taken into account according to growth depending dew point temperatures. While calculating optimum thickness f...
