A large scale experimental program using vertical and batter model piles in sand subjected to pull out loads has been carried out in a model tank of size 1m x 1m x 1m. Mild steel pipes of varying diameters, lengths, and shapes are used as model piles. A poorly graded river sand having specific gravity G= 2.67, Uniformity coefficient= 3.53, emax = 0.81, emin = 0.54 has been used as foundation me...

We present three variations of the following new sorting theme: Throughout the sort, the array is maintained in piles of sorted elements. At each step, the piles are split into two parts, so that the elements of the left piles are smaller than (or equal to) the elements of the right piles. Then, the two parts are each sorted, recursively. The theme, then, is a combination of Hoare's Quicksort i...

The lack of long-term performance and durability data of composite piles is an important concern that must be addressed to permit confidence in use of these piles for long-term load-bearing applications. Consequently, a durability study was undertaken to assess the rate degradation of mechanical properties (strength and stiffness) of commercially available glass fiber reinforced polymer (GFRP) ...

In this paper, inelastic pile-soil-structure interaction under static loading is presented by using finite element and boundary element methods. Linear beam column finite elements are used to model the piles and structural elements. Nonlinear soil is modeled by using nonlinear springs along the piles. Modified Özdemir’s nonlinear model is implemented for springs and systems of equations are cou...

We introduce Multi-User Piles Across Space, a technique that allows co-located individuals with PDAs to share and organize information items (e.g., photos, text, sound clips, etc.) by placing these items in shared, imaginary off-screen piles. This technique relies on human capacities to remember spatial layouts, and allows small co-located groups with limited screen real estate to collaborative...

This study investigated the effect of a 30-cm covering of finished compost (FC) on survival of Escherichia coli O157:H7 and Salmonella spp. in active static and windrow composting systems. Feedstocks inoculated with E. coli O157:H7 (7.41 log CFU/g) and Salmonella (6.46 log CFU/g) were placed in biosentry tubes (7.5-cm diameter, 30-cm height) at three locations: (i and ii) two opposing sides at ...

A state of the art presentation on prestressed piling as used throughout the world is discussed in this General Report to the FIP Symposium on Mass-Produced Prestressed Precast Elements in Madrid, Spain, May 1968. Historical information, design data and notes along with manufacturing techniques, installation practices, discussion of problems and failures and a complete bibliography are all cove...

Given n piles of tokens and a positive integer k ≤ n, we study the following two impartial combinatorial games Nimn,≤k and Nim 1 n,=k. In the first (resp. second) game, a player, by one move, chooses at least 1 and at most (resp. exactly) k non-empty piles and removes one token from each of these piles. For the normal and misère version of each game we compute the Sprague-Grundy function for th...
