Measurement of water content in expansive soil using a neutron moisture meter is strongly influenced by the moisture reactive property of this type of soil. It is particularly difficult to calibrate a neutron moisture meter when the dry density changes and the soil cracks during drying. This numerical study models the neutron probe measurement of soil moisture, based on a 7-group diffusion theo...

We exploit the techniques developed in [Le] to study N -expansive homeomorphisms on surfaces. We prove that when f is a 2-expansive homeomorphism defined on a compact boundaryless surface M with nonwandering set Ω(f) being the whole of M then f is expansive. This condition on the nonwandering set cannot be relaxed: we present an example of a 2-expansive homeomorphisms on a surface with genus 2 ...

begin{abstract} In this paper, we introduce an iterative method for amenable semigroup of non expansive mappings and infinite family of non expansive mappings in the frame work of Hilbert spaces. We prove the strong convergence of the proposed iterative algorithm to the unique solution of a variational inequality, which is the optimality condition for a minimization problem. The results present...

The application of stabilised soil in agricultural construction works such as shallow foundation fills and subgrade material for farm roads is demand due to the improved geotechnical properties. This study focused on improving compressive capabilities permeability characteristics rice husk ash (RHA)-treated clayey soils using basalt fibre. Basalt fibres are made from naturally occurring rock, y...

Subshifts are sets of configurations over an infinite grid defined by a set of forbidden patterns. In this thesis, we study two-dimensional subshifts of finite type (2D SFTs), where the underlying grid is Z and the set of forbidden patterns is finite. We are mainly interested in the interplay between the computational power of 2D SFTs and their geometry, examined through the concept of expansiv...

The type of soil known as expansive is capable changing its volume through swelling and contracting. These types soils are mostly composed montmorillonite, a mineral with the capacity to absorb water, which causes heave by increasing volume. Due their contract or expand in response seasonal fluctuations water content, these might prove be significant risk engineering structures. Many studies ha...

Owing to its propensity swell when in contact with water, expansive soil causes severe structural problems and shrinks they dry out. Soil stabilization is a well-known method used enhance the soil's physical engineering properties commonly adopted for improving structures. The mechanical of different soils evaluated by adding varying proportions marble dust (10, 20, 30 percent) Penjwen, Said Sa...
