 Abstract

The effectiveness of disc brake mainly depends on the rotor, and this the part which takes active part in development of required friction force to stop the vehicle. The disc brake rotor is provided with drilled holes to improve its cooling rate, which affects the structural stability of the rotor. Therefore the drilled holes on the rotor of disc brake is the origin of this investigation, to make possible modifications regarding the size, shape and orientation of drilled holes to reduce the stress concentrations. In the present work, model of disc brake rotor is created using Catia V5 and thus obtained model is analyzed using Ansys 15.0 towards the development of equivalent von-mises and maximum shear stresses and deformations. The analysis is repeated with series of disc brake rotors by varying the size of holes, and shape like elliptical and circular shapes and their orientation along the rotor to find the optimum combination for effective disc brake rotor with highest safety factor.

It is explicit to discover the appropriate response of the inquiry, in what conditions and upon what grounds is the desire of most investors vitiated? Along these lines, I have attempted to show what are subsidiary activities and the major complaints of subordinate activities. In explicit, when minority investors can apply to the on the ground of baseless bias cure and how far it has been polished in our country. At the same time, I have attempted to discover the components of uncalled-for bias and use of out-of-line bias tests lastly finished up with few ideas. At the point when an investor can carry an activity to control any proposed break of the organization's reminder or articles of affiliation or to pronounce any activity invalid dependent on such a penetration. I have likewise added the obligations owed to investors by and by. I have attempted to show that rights pronounced concerning the adjustment of Update or Articles of Relationship of the Organization, class rights, monetary help for and the buyers of an organization's offers, and division of exchange examination. I have attempted to, how far The Indian law varies from the Bangladesh, English, and Australian law (section 260 of the Australian Enterprises and protections enactment)

 Abstract

The top face of cylindrical piston influences the effectiveness of the engine efficiency by transmitting the maximum portion of power generated with minimum losses. Thus in this work, it is proposed to analyze the performance of the piston, by providing convex shape to the piston head with different radii of curvature. The piston is designed numerically and then the model is created in Catia V5 software, which further is analyzed using Ansys 15.0 software to study the equivalent von-mises stress distribution and deformation development and safety factor attained. The structural analysis is carried with series of the piston models with different radii of convex shaped head and comparison was carried among all the models and also with the piston model with flat head shape to find the optimum head shape of the piston for effective performance.

 Abstract

The cutting edge thought of social equity is worried about introducing another social request with no line which could get rights and benefits for the various segments of society overall and the helpless and oppressed segments of society specifically. As an entire, it is effectively that any veritable democratization interaction can be begun in India just through friendly equity. For that, the liberation of the Dalits, by a rebuilding of confidence, is particularly required. The vision of Dr. B. R. Ambedkar has given us an exhaustive program for accomplishing social equity in India. Thus, all reformist and majority rule powers must acclimatize the philosophy and vision of Dr. B. R. Ambedkar for the foundation of veritable social equity. The present paper highlights the philosophy of social justice advocated by Dr. B. R. Ambedkar.

 Abstract

Heart-related disorders are the most common health condition that can influence various aspects of life. Heart rate monitoring plays a vital role to predict health conditions. Telemedicine is providing health-related resources and information through telecommunications technology and electronic information. One of the most emerging trends in day-to-day life is the telemedicine system. This telemedicine system is evolving as a result of reducing the overall cost of the patient, in particular for disadvantaged patients and border area patients, by reducing travel allowances, hotel expenses, and the sum to be charged by specialists for some complicated illnesses. Patients do not need to consult with physicians with the use of telemedicine services, and patients may be able to obtain successful care from their locations or local hospitals.

 Abstract

In this thesis during the analysis of various fins configurations using ANSYS WORKBENCH be can compare the The heat transfer rate from the fins, outer wall and the overall heat transfer rate has been calculated and compared for various fin configurations. Also the surface nusselt number and surface overall heat transfer co-efficient has been found out. Temperature contours for various fin configuration has been plotted showing the convection loops formed around the heated pipe surface. Velocity contours for various fin configurations has been plotted and the motion of heated fluid is shown. The assumptions during the analysis have been taken considering the manufacturing and practical applications and working conditions. Hence the results obtained can be referred to while solving any such kind of problems in the practical field where only natural convection is under consideration. After comparing it is shown that we can find that the best configuration for this type of convective heat transfer of a heated pipe is a TRAPEZOIDAL fin as they have the highest total heat transfer rate . All the main parameters which can significantly influence the heat transfer performance of finned tube has been analyzed. Natural convection in a vertical tube without fins was taken as the reference tube and different fin patterns such as a single fin with large no. of turns like coiled shape and large no. of fins with single turn is compared with reference tube on the basis of different parameters such as heat transfer rate, surface nusselt number, heat transfer coefficient, fin effectiveness etc. There are some dimensionless numbers which affect the natural convection such as nusselt number which is the function of Reynolds number, grshof number and prandlt number, Rayleigh number which is the product of grashoff and prandtl number. After getting best fin configuration compared it with different fin profile such as rectangular cross section, tapered fin with trapezoidal cross section and hyperbolic cross section. All the computer simulation has been done on the ANSYS 13.0 .

 Abstract

In developing countries like India, the generation of construction and demolition (C &D) waste is increasing day by day. On the other hand, the reuse of construction waste is highly essential to preserve natural resources. Using the demolished concrete debris as recycled concrete aggregate conserves natural aggregates, reduces the impact on landfills, decreases energy consumption and can provide cost savings. The use of recycled aggregates in concrete results in significant economical and environmental benefits. In the present work, attempts have been made to assess the effect of recycled concrete aggregate on the strength of ordinary concrete. A study has been made on the properties of recycled aggregate which is to be used as coarse aggregate for M25 grade of Concrete. The percentage of recycled aggregate that partially replaced natural aggregate by weight was 0%, 10%, 20%, 30% and 40%. Concrete cubes were casted and tested in laboratories. Properties of aggregate and comparison of recycled aggregate concrete against natural aggregate concrete is performed according to requirements as such for its workability, compressive strength test. The results show that up to 30% replacements of natural aggregate with recycled aggregate there is a slight decrease in strength when compared with conventional concrete. But beyond 30% replacement there is a sudden fall in strength. The goal of this study is to develop the economical and sustainable concrete by using the concrete waste available in the site.
