The construction of roads on soft clay soils is a challenging task and therefore considered as one of the biggest
concerns in geotechnical engineering. The utilization of soft soils in tropical regions is currently low, although
construction on them has become increasingly necessary due to economic reasons. Recent developments in nanoscience
and nanotechnology opened fundamental and applied new frontiers in science and materials engineering. Advanced
materials are being developed with enhanced chemical and physical properties with unique characteristics. The properties
of these materials are determined not only by their composition and chemical bonds, but also by size and morphology.
However, the traditional cementitious stabilizers like cement are under discussion, not only for their negative
environmental effects during manufacture but also for their cost.

Unsaturated Hydraulic Conductivity of Bagasse Ash Treated Foundry Sand
Laboratory investigations were conducted to assess the unsaturated hydraulic conductivity of foundry sand
waste treated with up to 8% bagasse ash (a pozzolana) by dry weight of soil. Specimens were prepared at molding water
contents -2, 0 and +2 of the optimum moisture content using the four energy levels of reduced British Standard light,
British Standard light, West African Standard, and British Standard heavy. The predicted unsaturated hydraulic
conductivity of specimens were determined using the Brooks-Corey (BC) and Van Genuchten‟s (VG) models from
results of the soil water characteristic curve (SWCC). The unsaturated hydraulic conductivity decreases with increasing
matric suction for both models. While the unsaturated hydraulic conductivity decreases with increasing moulding water
content regardless of the compactive effort and bagasse ash content. The VG model gave a clearer trend as regarding the
influence of increasing bagasse ash content of the unsaturated hydraulic conductivity of treated and untreated specimen.
Finally, 2% and 4% bagasse ash treatment of specimens were the main treatment level of interest gave satisfactory for
use in covers for waste containment facility as the unsaturated hydraulic conductivity values generally recorded
satisfactory low values.

Numerical Analysis of Roller Compacted Concrete Pavement
There has been various design methods for roller compacted concrete (RCC) pavement during a several
decades. These design procedure are developed gradually. In this paper a 3D finite element (FE) model of RCC
pavement has been developed. . In the validation step, the results of 3D modelling are compared with those obtained by
theoretical approach. The comparison shows good correspondences. Due to the fact the theoretical approach uses 2D
model in the formula, the 3D FE model results were slightly lower than the theoretical model. Using finite element
software ABAQUS software, the paper investigated effects of changes speed in vertical displacement. In order to find the
effect of speed in typical RCC pavement with the assumed properties in section 3, five partition for the applying load has
created on the surface of slab. Vertical displacement at the bottom of the surface layer has been achieved for six different
speed. Considering the obtained results of vertical displacement of the pavement for four assumed speed, the fitted curve
is drawn with high accuracy.

Cloud Computing and Demand Based Services at a glance: Contemporary Scenario
Cloud Computing is one of the important name in the field of Computer and Information Science. Cloud
Computing is actually need of the hour. Cloud Computing is an important platform which is deals with virtualization.
This is a platform or more clearly an architecture which supports virtualization. And virtualization is including hardware,
software, packages, utilities and applications that means whole IT infrastructure. Cloud Computing and its evolvement
introduced so many facilities and services out of which demand based services treated as most important in many
perspective. This paper is deals with several aspects of cloud computing; including so many demand based services for
creation of healthy and sophisticated information infrastructure powered by advance technologies. Several facets reported
in this paper as per the R&D undertaken in ISOAH Data Securities Pvt. Ltd and also will be incorporated in the doctoral
thesis of the main researcher.

Survey of Semi Automatic Viscous Fluid Filling Machine
Pawar Mahesh S., Chavan Pranav A., Naigade Ajay P., Bamankar P.B., Dr. Pharande V. A.
Changes in today’s manufacturing environment allow tedious, fatiguing and repetitive tasks to be
mechanically performed by robots, as manually controlled work is transition to auto-cycle control equipment. Such
changes tend to take advantage of, and expand upon, operator process knowledge. As this trend continuous, the
operator’s contribution becomes more technically oriented and less physically oriented with significantly greater product
output being release. A robot is a reprogrammable multifunctional manipulator designed to move material parts, tools or
specialized devices through variable programmed motions for the performance of variety of tasks. The step by step
control and feedback is provided by a computer program run on either an external or embedded computer or a
