This report describes the static and dynamic loading of a 12-inch-wide by 18-inch-deep by 6-foot-long rigid footing, representing the strip footing of a subsurface shelter. Boundary conditions simulated those of a torsionally restrained footing of a flexible arch structure with simulated overburden of 20 feet at one side of the footing. Saturated and partially saturated sand was the test soil. ...

This paper presents an analytical model to estimate the cost of an optimized design of reinforced concrete isolated footing base on structural safety. Flexural and optimized formulas for square and rectangular footingare derived base on ACI building code of design, material cost and optimization. The optimization constraints consist of upper and lower limits of depth and area of steel. Footing ...

When the discussion turns to the creation of a European Research Council (ERC), a series of questions spring to mind. Answering some of them is now almost trivial—for example, “Why is an ERC needed and timely?”— whereas the answers to others, being more political, are certainly more difficult to envisage for most practising scientists. This is notably the case for the questions: “Who will be th...

The study of the charge excitations in cuprates is presently an interesting topic because development new and precise x-ray experiments. Based on a large-$N$ formulation two-dimensional $t$-$J$ model, which allows us to consider all possible equal footing, we investigate spectrum for both electron- hole-doped cases. In cases, instability toward phase separation, has momentum modulation ${\bf q}...

We develop a general framework for the study of strong Morita equivalence in which C∗algebras and hermitian star products on Poisson manifolds are treated in equal footing. We compare strong and ring-theoretic Morita equivalences in terms of their Picard groupoids for a certain class of unital ∗-algebras encompassing both examples. Within this class, we show that both notions of Morita equivale...

Q uantum secure communication relies on sharing of entangled states between parties. Over short distances (less than 100 km), these states can be distributed by sending photons over optical fibers, but losses in those fibers limit long-distance sharing. One solution is to use a sequence of “quantum repeaters” along the optical fiber connection [1]. These devices can store the quantum informatio...

A finite element program based on elastic –plastic model of Mohr-Coulomb criterion was used to evaluate the bearing capacity coefficients of soil under shallow strip flexible footing . The results were compared with others’ analytical results and it was found that the present study could offer quite consistent and rather precise values for the bearing capacity coefficients . &#10&#10The effect ...
