Experimental investigation on strength of concrete using plastics and metakaolin. -

- This paper presents the result of an experimental investigation carried out to find the suitability of metakaolin and plastic fibre in production of concrete. The conventional concrete M30 was made using OPC 53 grade and other mixes were prepared by replacing part of OPC with metakaolin and adding plastic fibre by weight of fine aggregate. The replacement metakaolin level were 5%,10%,15%,20% and from this finding the optimize value and kept constant further adding plastic fibre with 0.5%,1%,1.5% by weight of fine aggregate. All mixes were tested for compressive, spilt tensile and flexural strength at the end of 28 days. The test result indicates the metakaolin can be used effectively to replace 15% cement in concrete. The optimize value 15% kept constant and adding plastic fibre can be used effectively adding 1% by weight fine aggregate in concrete. - See more at: 

EXPERIMENTAL INVESTIGATION ON CONCRETE USING HYPO SLUDGE AND WOOD ASH.

The paper discusses the effects of using hypo sludge and wood ash ( prosopisjuliflora ash) as a partial cement replacement in concrete. An experimental study of concrete made with Ordinary Portland Cement (OPC) and 10% of OPC, replaced by hypo sludge. The hypo sludge 10% take as constant and further adding of wood ash from 0% to 30% as cement replacement for concrete. To determine the effect of these materials on concrete properties and was compared to control M20 mix. Concrete specimens were tested for compressive strength, tensile strength, and flexural strength at age of 28 days. - See more at:

Experimental Investigation on the Properties of Concrete with Carbon Black and PET. -

The New trends of construction methods sometimes cause harmful effects on environment though they are effective to mankind. Reuse of waste materials acts eco friendly also prevents exploitation of resources. Usage of such materials for construction purpose enhances the traditional methods of construction. In this paper presents an experimental investigation on the effect of PET (Polyethylene Terephthalate) on various strength properties. The strength properties of M40 grade concrete are studied with 0%, 10% and 20% of PET. There is decrease in strength when the ratio of PET to fine aggregate was increased. So that the PET percentage is taken as constant, the Carbon Black as a partial replaced by cement with 0%, 10%, 20%, and 30%. The strength properties were again studied and its results are compared to conventional concrete. - See more at: 

Effect of Suspended Particles and Magnetic Field on Thermal Convection in Ferromagnetic Fluid with Varying Gravitational Field in Porous Medium. -

The aim of this paper is to study the effect of magnetic field and suspended particles on thermal convection in ferromagnetic fluid with varying gravity field saturating in a porous medium. A linear stability analysis and normal mode analysis methods are used to find the exact solution for a ferromagnetic fluid layer contained between two free boundaries. A dispersion relation governing the effect of magnetic field, suspended particles and medium permeability is derived theoretically. From the analysis, we have found that in case of stationary convection, the magnetic field has stabilizing effect on the system for λ>0 and has a destabilizing effect for λ<0. For stationary convection, it is also found that suspended particles and medium permeability have destabilizing effect on the system under the condition λ>0 whereas for λ<0, the nature of their effect reverses i.e. both parameters stabilizes the system for λ<0. Further, the case of oscillatory mode is also considered. It is found that the principle of exchange of stabilities is valid for the problem under certain condition. The effect of all studied parameters on ferromagnetic fluid is also verified numerically. - See more at: 

Experimental Investigation on the Effect of Bagasse Ash and Rubber tyre waste in Concrete. -

The utilization of industrial and agricultural waste produced by industrial process has been the focus on waste reduction research for economical, environmental and technical reasons. SCBA is a fibrous waste product of the sugar refining industry, along with ethanol vapor. Bagasse ash mainly contains aluminum ion and silica. The use of SCBA as a pozzolonic material for producing high strength concrete. OPC is partially replaced with finely SCBA. At present the disposal of waste tyre is becoming a major waste management problem in the world. In this project, the bagasse ash has been chemically and physically characterized and partially replaced in the ratio of 0%, 5%, 15% and 25% by weight of cement in concrete. The mix proportion for M30 grade concrete was derived. Rubber tyre waste has been used as coarse aggregate with replacement of conventional coarse aggregate and it is taken as constant of 10%. - See more at:

Improved Face Recognition Method usingPCA.

This paper provides an example of the face recognition using PCA method and effect of Graph Based segmentation algorithm on recognition rate. Principle component analysis (PCA) is two or more variabletechniquethatanalyzesafacedatainwhichexperiencearedescribedbyseveralinter-correlateddependentvariables.Thegoalisto extract the important information from the face data, to represent it as a set of new statistically independent variables called principal components. The paper presents a proposed methodology for face recognition based on preprocessing face images using segmentation algorithm and SIFT (Scale Invariant Feature Transform) descriptor. The algorithm has been tested on 50 subjects (100images). The proposed method first waste stedon ESSEX face data base and next on own segmented face data base using SIFT-PCA. The experimental result shows that the segmentation in combination with SIFT-PCA has a positive effect for face recognition and accelerates the recognition PCA technique. - See more at: 

MODELLING OF LIQUID PROPELLANT SLOSHIN A RECTANGULAR TANK BY VARYING BAFFLE HEIGHTS. -

Sloshing occurs in fractionally-filled containers that undergoes accelerated motion. It is a phenomenon of fluid-structure interaction. A study of a rectangular fuel tank filled with kerosene was simulated in this paper using Volume of Fluid (VOF) multiphase model. Simulations compared the velocity, turbulence and wall shear stress in the tank by varying the baffle heights. CFD analysis was carried out using a commercial finite volume package ANSYS FLUENT 16.0. The tank was set into motion by giving an acceleration of 9.81 m/s2 in the Z direction. It was found from the CFD simulations that the sloshing in the fuel tank was significantly reduced with the introduction of baffles in the fuel tank. The damping effect of the baffles was clearly visible in the tank with baffles that is 50% of its total height from the obtained results. Further research can be undertaken by introducing holes and by varying the size of the holes in the baffles in order to further reduce the sloshing in the fuel tank. - See more at:
