This paper summarizes recent investigations into the structural and material response of ambient-dry wet clay-brick lime-mortar masonry elements, with focus on those used in heritage structures Historic Cairo. In addition to cyclic tests large-scale walls subjected lateral displacement compressive gravity loads, studies included complementary small scale panels specimens. It is shown that moist...

The paper discusses the application of the Wave Based Method (WBM) for the steady-state acoustic response prediction of a car cavity up towards the mid-frequency range. After explaining the need for new prediction tools, the mathematical background of the WBM is given. The prediction results are compared with the results obtained by the Finite Element Method (FEM). For validation purposes, both...

Multibody dynamic simulations are performed for a large deployable space structure using ®nite element models and an explicit temporal integration procedure. The structure considered is NASA's light-weight, 8 m-aperture next generation space telescope (NGST). The NGST structure consists of beam components (modeled using beam ``super-elements'', each composed of two truss elements and a torsiona...

A computer code is developed to accurately simulate the three-dimensional heat transfer during the thermoset fiber placement composite manufacturing process. The code is based on the Lagrangian formulation of the problem. Eight-node brick elements are employed, and the 2 2 2 integration rule is used to numerically evaluate the integrals over an element. The coupled ordinary differential equatio...

The article presents a proposal of a model of fatigue destruction of hydrophobised ceramic brick, i.e., a basic masonry material. The brick surface was hydrophobised with two inorganic polymers: a nanopolymer preparation based on dialkyl siloxanes (series 1-5) and an aqueous silicon solution (series 6-10). Nanosilica was added to the polymers to enhance the stability of the film formed on the b...

A brick is a 3-connected graph such that the graph obtained from it by deleting any two distinct vertices has a perfect matching. Bricks are building blocks of the matching decomposition procedure of Kotzig, Lovasz and Plummer, and therefore many matching-related problems can be reduced to bricks. We prove, roughly, that every brick other than the Petersen graph can be generated from a “matchin...

In this work was investigated the feasibility to use Waste Electrical and Electronic Equipment (WEEE) glasses in construction sector as secondary raw material. WEEE glasses were used in different percentages as a function of the product obtained: 30-40wt% for glaze formulations, about 40wt% for glass-ceramics and 5wt% in brick bodies. The laboratory and industrial scale up results demonstrated ...

Egecioglu, ii. and J.B. Remmel, Brick tabloids and the connection matrices between bases of symmetric functions, Discrete Applied Mathematics 34 (1991) 107-120. Let H, denote the space of symmetric functions, homogeneous of degree n. In this paper we introduce a new set of combinatorial objects called I-brick tabloids and its variants, which we use *to give combinatorial interpretations of the ...
