Proper estimation of foundation settlement is a crucial factor in designing shallow foundations. Recent literature shows the applicability of Artificial Neural Networks (ANNs) in predicting the settlement of shallow foundations. However, conventional ANNs have some drawbacks: getting trapped in local minima and a slow rate of learning. Utilization of an optimization algorithm such as Particle S...

This paper presents a case study of geotechnical design of bridge foundations and approaches in hilly granite formation in northern New South Wales of Australia. Firstly, the geological formation and existing cut slope conditions which have high risks of rock fall will be described. The bridge has three spans to be constructed using balanced cantilever method with a middle span of 150 m. After ...

Using charge-accumulation imaging, we measure the charge flow across an incompressible strip and follow its evolution with magnetic field. The strip runs parallel to the edge of a gate deposited on the sample and forms at positions where an exact number of integer Landau levels is filled. An RC model of charging fits the data well and enables us to determine the resistance across the strip. Sur...

during a two-year (2004-2005) survey of alfalfa aphids and their natural enemies in isfahan, a total of four aphid species and 58 species of their natural enemies comprised of 45 predatory species, 11 parasitoid species and two species of parasitic mites were collected and identified. moreover, five hyperparasitoid species were collected. on each sampling date, six 20-sweep samples were taken u...

We measured the inter-strip capacitance on a prototype DC-coupled "stripixel" detector (SPD) employing circular spirals with two methods, each of them employing a RC-chip to bias and read out the detectors. Both yielded the same value of Cint = 1.1 pF for a strip length of 1.4 mm, indicating the total inter-strip capacitance to be much larger than on ordinary silicon strip detectors (SSD).

The aim of the present numerical study was to analyse pressure settlement behaviour and bearing capacity asymmetric plus shaped footing resting on loose sand overlying dense at varying embedment depth. investigation carried out using ABAQUS software. effect depth embedment, friction angle upper lower layer thickness studied in this investigation. Further, comparison results made between symmetr...

‘For an isotropic, homogeneous and linearly elastic sheet subjected to selfequilibrating edge stresses over a portion of its boundary and free of surface and edge load otherwise, an explicit rate of decay of the stresses in the sheet was given in [1 ]. In particular, the stresses in a semi-infinite rectangular strip subjected to self-equilibrating in-plane normal and shear stress resultants alo...

PURPOSE The aim of this study was to evaluate a newly-designed mitral annuloplasty strip (the Mitra-Lift(®) strip) in patients undergoing mitral valve repair for mitral regurgitation (MR). METHODS A total of 30 patients who underwent posterior mitral strip annuloplasty for moderately severe to severe MR were evaluated in this study. The strip annuloplasty (SA) consisted of the use of the newl...

Strip format maps constitute a unique, but often overlooked form of cartographic representation. The purpose of this paper is to combine a historical overview of cartographic applications of the strip format with an evaluation of current implications of continued use of this technique. In addressing these goals, four factors that relate to use or selection of strip maps a t various points in hi...
