NUCLEATION  AND GROWTH THEORIES OF SOLID TO LIQUID,LIQUID TO GAS AND GAS TO SOLID TRANSFORMATIONS Nucleation is as a physical process in which there is change of state —liquid to solid —around certain focal points which are called nuclei. Examples- • When tiny water droplets nucleate from the supersaturated wet air and cools it forms … Read more

For my dissertation I have decided to cover the shortage in skilled labourers in the construction industry. I have chosen this because I believe that we mainly overlook this, by not taking into account the impact which skilled workers play in the industry.  I personally believe that the fact that the construction industry is a … Read more

Use of internet and e-commerce is growing very rapidly. Many products are available online. Most of the retail websites encourages consumers to write their feedbacks about products to express their opinions on various aspects of the products.   This gives rise to huge collection of reviews on web. These reviews contain rich and valuable knowledge … Read more

Composite materials are materials made from two or more constituent materials with different properties combining to produce a material with characteristics different from the individual components. The new material formed will be stronger, lighter or cheaper than traditional materials. Ex: Fibre reinforced plastics   Laminates are the products made by bonding together two or more … Read more

2.0 LITERATURE RIVIEW 2.1 Literature Survey on Different Research Papers The aspect of engineering research is dynamic in nature. This is because different people do work in some areas to some extent and give room for other people to do further work.

INTRODUCTION Security means protecting the information perfectly.Security primitives are based on hard mathematical problems.Since security primitives are used as building blocks,they must be very reliable.Since creating security routines are very hard.It involves security primitives are, 1. Designing a new security primitive is very time-consuming and very error prone,even for exports in the field. 2. Security … Read more

Ductility is more important property for the seismic forces. Ductility for other structural requirements-preventing progressive collapses and disproportionate collapses. Ductility: The ability of a structure to deform plastically under load without fracture yet still fulfill a load carrying function. Example when considering dynamic loads, the energy absorbed during deformation becomes an important resistance characteristic. It … Read more

Construction practice including modern materials and methods, Bituminous and Concrete road construction   Prefabricated Components: Specialty Portland Cement Concretes: New generations of specialty concretes have improved one or more aspects of performance and allow for greater flexibility in highway design and construction. High-performance concrete typically has compressive strengths of at least 10,000 psi. Today, ultra-high-performance … Read more

Earthquake is one of the greatest natural disasters which cause immense damage to properties and human lives. As a part of an earthquake resistant building design, shear walls are provided in buildings to reduce lateral displacements under earthquake loads. The objective of the study is to study the non-linear behavior of shear wall with edge … Read more

”Abstract: Secure deduplication is a system for disposing of copy duplicates of capacity information, and gives security to them. To decrease storage room and transfer data transmission in distributed storage deduplication has been a surely understood strategy. For that reason concurrent encryption has been broadly embrace for secure deduplication, discriminating issue of making united encryption … Read more
