The construction industry is growing fast alongside the growth of economy and population. As one major building materials, brick in high demand for purposes. continuous will eventually lead to a shortage raw materials long run, such as sand Ordinary Portland cement. This issue could be resolved by utilizing waste Expanded Polystyrene (EPS) beads Silica Fume (SF), replacement cement production b...

Complex time-varying phenomena usually produce volume datasets that are not static but dynamic in time. The amounts of storage and the computing power needed to visualize such datasets can easily exceed what could be offered by a single processor. Therefore, networks of computers are ideal to render them. However, data distribution schemes can be highly vulnerable to how the user wants to visua...

Bricks-and-mortar companies wishing to create value-added Internet services do so in a business environment that is characterized by great uncertainty and, hence, formulating a coherent business strategy is exceedingly challenging. This paper presents a case study based analysis of the evolving eBusiness strategy of a bricks-andmortar grocer contrasted with the strategies of other competitors. ...

Large datasets are most economically trnsmitted via parcel post given the current economics of wide-area networking. This article describes how the Sloan Digital Sky Survey ships terabyte scale datasets both within the US and to Europe and Asia. We 3GT storage bricks (Ghz processor, GB ram, GbpsEthernet, TB disk) for about 2k$ each. These bricks act as database servers on the LAN. They are load...

A polycube in dimension d is a finite union of unit d-cubes whose vertices are on knots of the lattice Zd . We show that, for each family of polycubes E, there exists a finite set F of bricks (parallelepiped rectangles) such that the bricks which can be tiled by E are exactly the bricks which can be tiled by F . Consequently, if we know the set F , then we have an algorithm to decide in polynom...

Time-dependent natural weathering processes suffered by historic bricks in Toledo (Spain) improve their physicomechanical properties by porous infill with gypsum, ettringite and mainly calcite. Both, these bricks and their experimental replica bricks, made from the original calcareous clays fired at the probable historical temperatures (700o 900oC), have been analyzed by X-ray diffraction, opti...

naturally occurring radionuclides have different amount of activity concentration for 226 ra, 232 th and 40 k in building materials. in this study, natural radioactivity has been measured for bricks used in tehran. for this work, 9 samples of three types of bricks, clay brick (cb), making the facade brick (mfb) and firebrick (fb) has been selected from different regions and factories in tehran....

The work deals with the impact of crushed brick on properties Portland cement binder. source recycled materials is not only demolition waste, but also waste from production. One way to reduce amount this recyclate use it in cement-based composite. advantages using bricks as aggregate are their lower bulk density compared conventional aggregates. Economic and ecological benefits important, becau...

This is the first study of adobe brick contamination anywhere in the world. Huancavelica, Peru is the site of historic cinnabar refining and one of the most mercury (Hg) contaminated urban areas in the world. Over 80% of homes in Huancavelica are constructed with adobe bricks made from Hg contaminated soil. In this study we measured total Hg concentrations in adobe brick, dirt floor, surface du...
