Experimental Investigations on Cement Concrete by using Waste Steel as a Fibre in Concrete

As the technology is getting advanced day by day bringing the enhancement in comfort level of the human beings for example use of plastic containers. The use of plastic and metal containers has became very popular for carrying any liquid or semi liquid content. But if we see as per the rule of nature every action has a reaction likewise after looking at the advantages there are many disadvantages for example the plastic material used for making is not decomposible naturally and has to be taken care of artificially. So the researchers today are finding the way out for processing, recycling or reusing such material for some other purpose. In today scenario the constructions globally are increasing rapidly so there is a need of the construction industry to find out the cost effective materials for increasing the strength of concrete structures. Keeping this in mind the researcher has decided to study the influence of addition of waste materials like lathe waste, soft drink bottle caps, empty waste tin, waste steel powder as a mixing material with the concrete in the percentage of maximum 1 to 1.2 of total weight of concrete. All the scrap material mentioned above was collected and processed in to strips of approximately size of 15 to 25 mm. Today due to Global warming there is a need of using maximum quantity of such recyled material by which we can conserve the natural resources and reduce the amount of materials going to our landfills. Large quantities of metal waste are generated from empty metal cans and bottle caps of juices and soft drinks. This is an environmental issue as metal waste is difficult to biodegrade and involves processes either to recycle or reuse. Today the construction industry is in need of finding effective materials for increasing the strength of concrete structures with low cost, and with less environmental damage. In this study the researcher has tried his level best for the positive results by using the waste or scraped metal material as a partial substitute for coarse aggregate with the help of orange leaves powder as a plasticizer. The parameters like slump, demoulded density, split tensile strength, compressive strength, flexural strength properties at different percentages replacement of coarse aggregate with waste bottle caps were investigated in the laboratory. In this investigation, after conducting certain laboratory tests the researcher has done the comparison between plain cement concrete and the metal fiber reinforced cement concrete in various proportions by weight. The metal fibers used in this study were irregular in shape and varying aspect ratio. Analytical comparison of both the samples was done for the parameters like compressive strength, tensile strength and flexural strength. After the completion of 28 days the strength of metal fiber reinforced material concrete was found increased when compared with the strength of plain cement concrete. This study was conducted with M30 cement.

Investigation of Nonlinear Damped Vibrations of a Hybrid Laminated Composite Plate Subjected to Blast Load

Hybrid composite is a composite which contains of nanoparticles to improve the strength as related to conventional composites. A model has been projected to define the elastic properties of hybrid composite. The hybrid composite contains of predictable fiber and nanocomposite as matrix. The first step here is to define the properties of nanocomposite which is done by using Mori "“ Tanaka method. The CNTs are deliberated as cylindrical inclusions in polymer matrix in Mori "“ Tanaka method. Arrogant perfect bonding among carbon fibers and nanocomposite matrix, the actual properties of the hybrid composite has been estimated using mechanics of materials approach. An 8 noded shell element has been used for the finite element analysis taking 5 degrees of free do mesh node u, v, w, x, y .A10 10 finite element mesh proceed sun remitting happening the convention of characteristic the shell element. The shell coordinates which are in Cartesian form are transformed into parametric formusing twoparameters 1, 2 . Theseparametersare over mapped into isoperimetric form , . A 16 layered enclose with stacking arrangement 0 454590 2S has been recycled for vibration investigation of simply supported shell element. The dynamic equations of shell are resultant using Hamilton's principle. As the damping types of the dynamic system are not available, for further analysis damping ratio of first mode and last active mode are presumed. Using Rayleigh damping the damping ratios of intermediate modes can be considered. The time decay of the structure from maximum amplitude to 5 of the maximum amplitude has been used as a parameter to study some shell structures by varying the volume fraction of CNTs in nanocomposite and by changing carbon fiber volume fraction.

Analysis of Statistical Properties of Eye Lens Images to Detect Cataract at Earlier Stage

Cataract is clouding of eye lens cause partial or complete blindness. Aging of eye lens or injury to eye lens are major reasons to cause cataract. Smoking and use of excessive use of steroids also leads to development of cataract. Clumping of protein molecules and water molecules in natural eye lens leads of development of Cataract. Opacity at center of lens it is called as nuclear cataract while at edges of lens is called cortical cataract. The lens focuses the reflections form object at retina and causes clear vision. The opaqueness of lens at center position due to nuclear cataract causes the incorrect image formation at retina causing poor vision. Detection of same at earlier stage may help to correct vision by us of external lens. The patient may be advised treatment to prohibit the further growth of cataract. In research work presented slit lamp images with image processing techniques are used to detect the cataract at earlier stage. The wide slit illumination images are used to detect cataract. In the proposed system Hough circle detection transform is preferred to extract lens structure. The mask is created using lens center and radius extracted from Hough circle detection transform. The lens without cataract is having less mean value and uniformity compared to lens wit cataract. These statistical parameters are independent on scale and size of image. The graphical user interface is developed to automate and to make system access user friendly.

THD Analysis of Cascaded Multi level Inverters using different PWM Techniques

Multi level inverters MLI are used in places or industries that require very high voltage and huge current. Multi level inverter topologies have various advantages over single level converters. These advantages are like rise in output voltage, reduction in the total harmonic distortion THD , reduction in electro magnetic interference EMI generation etc. Key attribute of a multi level inverter is the reduction in the voltage stress on each power device. This reduction is due to the use of several levels available on the DC bus. The dawn of multi level inverter topologies have created requirement of various pulse width modulation techniques. In this paper authors have used PWM technique, by which the total harmonic distortion of the multi level inverter is decreased. In this we have also 

controlled the speed of the induction motor by supplying the power through a multi level inverter.

Design, Optimization and Analysis of a Radial Active Magnetic Bearing for Vibration Control

The most important aim of the project is to make use of the active vibration control technique to reduce vibration in composite shaft system using three nodded beam element. The fiber reinforced polymer FRP composite shaft is deliberate in this paper considering it as a Timoshenko beam. Three dissimilar isotropic rigid disks are mounted on it and also supported by two active magnetic bearings at its split ends. The work involves finite element, vibration and rotor dynamic analysis of the structure. Rotary inertia effect, gyroscopic effect kinetic energy and strain energy of the shaft are derived and studied. The governing equation is obtained by applying Hamilton's principle using finite element method in which four degrees of freedom at each node is considered. Active control scheme is applied through magnetic bearings by using a controller containing low pass filter, notch filter, sensor and amplifier which controls the current and correspondingly control the stability of the whole rotor shaft system. Campbell diagram, steadiness limit speed diagram and logarithmic decrement diagram are considered to establish the system stability. Effect of different types of stacking sequences are also studied and compared
