To reduce maintenance costs, municipalities and schools are starting to replace natural grass fields with a new generation synthetic turf. Unlike Astro-Turf, which was first introduced in the 1960s, synthetic field turf provides more cushioning to athletes. Part of this cushioning comes from materials like crumb rubber infill, which is manufactured from recycled tires and may contain a variety ...

Abstract—Coal fly ash, an industrial by product of coal combustion thermal power plants is considered as a hazardous material and its improper disposal has become an environmental issue. On the other hand, manufacturing conventional clay bricks involves on consumption of large amount of clay and leads substantial depletion of topsoil. This paper unveils the possibility of using fly ash as a par...

This paper describes the testing of Profiled Steel Sheet Dry Board (PSSDB) load bearing wall system. Experimental tests were conducted on various PSSDB wall samples, with and without infill materials to study its effect on the PSSDB load bearing wall performance. A proprietary profiled steel sheet, Ajiya Cliplock (0.48 mm thick) attached to Cemboard (10 mm thick) on one side, and Cemplank (10 m...

We give a new proof of the following interesting fact recently proved by Bower and Michael: if a d-dimensional rectangular box can be tiled using translates of two types of rectangular bricks, then it can also be tiled in the following way. We can cut the box across one of its sides into two boxes, one of which can be tiled with the first brick only and the other one with the second brick. Our ...

We consider the realtime content-based image retrieval of LEGO bricks from a database of images of LEGO bricks. This seemingly simple problem contains a number of surprisingly the image signature, and corresponding feature set, and illustrate cellular automaton-based methods for the whole feature extraction phase.

Three-dimensional printing technologies are transforming various sectors with promising technological abilities and economic outcomes. For instance, 3D-printed concrete (3DPC) is revolutionizing the construction sector a promise to cut projects’ costs time. Therefore, 3DPC has been subjected extensive research development optimize mechanical thermal performance of walls produced by 3D printing....

<p class="Abstract">To optimize the 3D printing process, influence of its parameters on performance process needs to be investigated. This research investigates effect infill pattern, density, and angle time filament material length. First, this collected length data for each combination angle. The collection was conducted by implementing Repetier-Host v.2.1.6 software as a acquisition to...
