This paper presents the characteristic strength behaviour of Bamboo Leaf Ash (BLA) blended cement concrete in sulphate environment. A total of 66 concrete cubes of 150mm x 150mm x 150mm were produced with OPC-BLA blended cement, the partial replacement of OPC by BLA was varied from 0% to 15% in the concrete. The specimens were tested and crushed to obtain their compressive strengths at age 21, and 28 days of curing in different media (Na2SO4, CaSO4a and MgSO4 at 0.5%, 1.5% and 2.5% concentration). The choice of the percentage concentration of chemicals used as curing media was based on a similar research carried out by [1-2]. The 28 days strengths obtained for 5%, 10% and 15% replacement of BLA increases when compared with the results obtained at 21 days. The results also increased as the concentration of the sulphate increases, it shows that very high concrete strength values could be obtained with OPC-BLA blended cement concrete when high control measures are applied and at longer days of hydration and in sulphate environment. Therefore, OPC/BLA blended cement concrete could be used in civil engineering and building works in sulphate environment and where early strength is not a major requirement, thereby reducing the cost of production.

Wireless Power transmission (WPT) is a useful and convenient technology that can be employed to collect solar energy and concentrate on earth surface without the need for a wire connection called a solar power satellites (SPS). This paper provides an analysis of wireless power transfer with an assessment of its practical applicability in terms of power range and efficiency. In this paper, various technologies available so far for wireless transmission of electricity and the need for a Wireless Energy Transmission will be discussed to find its possibility in actual practices. Also, their advantages, disadvantages and economical consideration will also be presented. This paper concentrates mainly on (i) The most popular concept known as Tesla Theory, (ii) The microwave power transmission(MPT) called Solar power satellite, and (iii) The highly efficient fibre lasers for wireless power transmission. Many concepts, research papers, and patents are available on wireless transmission of electricity but the commercial technologies are yet to be materialized. This paper will also discuss the possible ways to get useful and practical results out of all researches carried out so far elsewhere. The output microwave power ranges from 50W to 200W at 2.45GHz. A coaxial cable is to connect the output of the microwave source to a coax-to-waveguide adapter. This adapter is connected to a waveguide ferrite circulator which protects the microwave source from reflected power. The circulator is connected to a tuning waveguide section to match the waveguide impedance to the antenna input impedance.

Manufacture of Portland cement produces large of volumes of carbon dioxide and other gases. Releasing these gases causes atmospheric pollution and subsequent environmental degradation. Finding a suitable alternative solution to mitigate the environmental degradation caused by using Portland cement is very important for environmental sustainability. The use of geopolymer concrete as an alternative material over Portland cement concrete to reduce the adverse effects on the environment is investigated in this paper. The paper also critically analyses the economic and environmental benefits of geopolymer concrete and address the financial and environmental issues associated with the production and use of Portland cement. Geopolymer cement utilizes industrial waste materials such as fly ash from thermal power stations to provide a practical solution to waste management as well as environmental protection methods.
Geopolymer concrete products are known to possess far better durability and strength properties than Portland cement concrete. These properties are investigated extensively in laboratory to verify and confirm the superior durability and strength properties. The paper also discusses the factors which restrict the use of geopolymer concrete as an alternative to Portland cement concrete. Laboratory tests are conducted on compressive strength, split tensile strength and flexural tests for specimens with combination of different molarity. The results obtained are compared analytically and graphically

The Advanced Encryption Standard (AES) a symmetric-key block ciphertext published by National Institute of Standards and Technology (NIST)[1]. Order to protect a data high throughput masked Advanced Encryption Standard (AES) is used. The masked AES engine uses the unrolling techniques which required extreme level in large field programmable gate array (FPGA). The area optimization in masked AES with an unrolled structure. The mapping of operation from GF(28) to GF(24) as much as possible in order to optimize area. The number of mapping is reduced [GF(28) to GF(24)] and inverse mapping [GF(24) to GF(28)] operation of the SubBytes by step from zero to nine. In order to compatible, the masked MixColumns, masked AddRoundKey, and masked ShiftRows including the redundant masking values are carried over GF(24). By moving, mapping and inverse mapping outside the masked AES‟s round function, area can be reduced by 20%.

Today, detection and tracking is vital to many applications dealing with image sequences such as video surveillance like military, defense systems, law enforcements and cryptography. In object based coding, video frames are defined in terms of layers of Video Object Planes(VOP).With the development of modern technology more attention has been shifted towards spatial resolution for object recognition, mapping and image capabilities. Unexpected shadows effect its resolution. Removal of shadow from VOP's will assist the applications for comprehensive detection of activities. While transmitting video through unstructured network makes it vulnerable to many attacks. In order to protect the video content from attacks, digital watermarking is necessary. In this project, we implement to achieve an efficient algorithm for the watermarked VOP sequences by applying hybrid transformation techniques.

By using one-electron Hamiltonian for describing the dynamics of interaction between species and solid surface in the scattering process, in the presence of a monochromatic electromagnetic field (laser field), we present detailed theoretical treatment and model calculation to describe the surface-ion charge exchange mechanism. We apply our treatment to the scattering of  Li from KF insulator surface. Our application ensure that the species charge state can be controlled by the laser field.

The present work is carried out on modeling, analysis and testing of suspension spring is to replace the existed steel helical spring used in popular two wheeler vehicle. The stress and deflections of the helical spring is going to be reduced by using the new material. The comparative study is carried out between existed spring and new material spring. Static analysis determines the stress and deflections of the helical compression spring in finite element analysis. The testing proto type is used to test the spring under different loading conditions. Finite element analysis methods (FEA) are the methods of finding approximate solutions to a physical problem defined in a finite region or domain. FEA is a mathematical tool for solving engineering problems. In this the finite element analysis values are compared to the experimental values. A typical two wheeler suspension spring is chosen for study. The modeling of spring is developed on pro/E 5.0 analysis is carried out on ansys 14.
