1 Experimental study on strength of concrete by using Metakaolin
Shashikant Dewangan, Nidhi Gupta

Abstract-Concrete is that pourable mix of cement, water, sand, and gravel that hardens into a superstrong building material. Supplementary cementing materials (SCM) have become an integral part of concrete mix design. These may be naturally occurring materials, industrial wastes or, by products or the ones requiring less energy to manufacture. Some of the commonly used SCM are fly ash; silica fume (SF), GGBS, rice husk ash and metakaolin (MK), etc. metakaolin is obtained by the calcination of kaolinite. It is being used very commonly as pozzolanic material and has exhibited considerable influence in enhancing the mechanical and durability properties of concrete. In this paper, experimental study was carried out on M 50 grade of concrete. In this concrete cement was replaced by metakolin. In various percentages such as 5%, 10%, 15%, 20%, 25% concrete specimens containing metakaolin were studied for their compressive strength.

2 Performance on split tensile strength of concrete with partial replacement of cement by ground granulated blast furnace and sand by quarry dust
Yogesh Soni, Nidhi Gupta

Abstract-Concrete is the most widely used construction material in civil engineering industry because of its high structural strength and stability. Cement and sand is a major constituent material of the concrete which produced by natural raw material like lime and silica and natural sand respectively. Once situation may occurs there will be no lime on earth production of cement also natural sand. This situation leads to think all people working in construction industry to do research work on cement replacing material and natural sand for use of it. The construction industry is constantly looking for supplementary cement and natural sand material with the objective of reducing the solid waste disposal problem. Ground granulated blast furnace slag (GGBS), quarry sand are the solid wastes generated by Industry. To overcome from this crisis, partial replacement of Cement with GGBS, natural sand with quarry sand (QS) can be an economic Alternative. The cubes are tested for compressive strengths. Ordinary Portland cement was partially replaced by by GGBS 0%, 30%, 40%, 50% and natural sand replacement by QS 0%, 40%, 50%, 60%.

3 A New Multilayer STFC Encoder for Fading Free MIMO Communication
Ankit Soni, Prof. Rajender Singh Yadav

Abstract-In this paper, we propose a multilayered space-frequency block coded OFDM system, which is a combination of the vertical layered space-time architecture, known as V-BLAST, and the spacefrequency block coded OFDM system. This system is designed to provide reliable as well as very high data rate communications over frequency-selective fading channels with low decoding complexity. Orthogonal Frequency Division Multiplexing (OFDM) is used to transform the frequency-selective fading channel into multiple flat fading sub-channels. Using four transmit and receive antennas at a data rate of 4 Bits/Sec/Hz, we achieve a diversity gain of about 4.5 dB over the conventional layered space-frequency coded OFDM structures (VBLAST-OFDM) at a bit error rate of 10-3.

4 A unique mixer of Wavelet Transform and Ramez Exchange Algorithm for Hearing filters
Shivani Tiwari, Rakesh Patel, Shobhit Verma

Abstract-Filters became important when noise in signals causes loss of actual information. Many filters have been developed and still improving. Paper presents an audio enhancement system that aims to recover common audio signal from received noisy audio signal after long communication. We do so in the context where each received is uniquely corrupted. To this end, we propose a method of DWT remez exchange to analyses on synchronized inputs. In the proposed model, some of the parameters are fixed. Our model also allows for prior knowledge about the parameters of the model, A highly optimized core discrete Remez part of the Parks-McClellan (PM) filter along with wavelet type sym6 filter been proposed in the paper. As available PM and Wavelet filters are already an achievement and works quite good but some time we requires to have filter highly resolution filters which have high SNR, low BER and very low MSE for any input signal.

7 Anonymous Authentication of Cloud Data with Decentralized Access
G.Durga Veni, Akella Subhadra

Abstract-Cloud Computing is the emerging technology where we can get platform as a service, software as a service and infrastructure as a service. When it comes to storage as a service, data privacy and data utilization are the primary issues to be deal with. Security and privacy are very important issues in cloud computing. Distributed access controls of data stored in cloud so that only official users with suitable attributes can access them.Users are genuine who store and modify their data on the cloud. The identity of the client is protected from the cloud during authentication. The construction is decentralized, meaning that there can be several KDCs for key management. Revoked users cannot access data after they have been revoked. The proposed scheme is resilient to replay attacks. The protocol supports multiple read and writes on the data stored in the cloud.It proposing privacy preserving authenticated access control scheme. According to the scheme a user can create a file and store it securely in the cloud. The cloud verifies the authenticity of the user without knowing the user’s identity before storing data. The scheme also has the added feature of access control in which only valid users are able to decrypt the stored information. The scheme prevents replay attacks and supports creation, modification, and reading data stored in the cloud. The work proposes a new decentralized access control scheme for secure data storage in clouds, which supports anonymous authentication .Moreover, our authentication and access control scheme is decentralized and robust, unlike other access control schemes designed for clouds which are centralized.

9 Improvement of Power Quality Using New Control Algorithm Based Dynamic Voltage Restorer
Kottam Niranjan, Arja Madhusudana Rao, S. Laxmi prasanna

Abstract- The problem of voltage sags and swells and its major impact on sensitive loads are well known. To solve this problem, custom power devices are used. One of those devices is the Dynamic Voltage Restorer (DVR), which is one of the most efficient and effective modern custom power devices used in power distribution networks. A new control algorithm for the DVR is proposed in this paper to regulate the load terminal voltage during sag, swell in the voltage at the point of common coupling (PCC). This new control algorithm is based on synchronous reference frame theory (SRF) along with PI controller is used for the generation of reference voltages for a dynamic voltage restorer (DVR). These voltages, when injected in series with a distribution feeder by a voltage source inverter (VSI) with PWM control, can regulate the voltage at the load terminals against any power quality problem in the source side. It first analyzes the power circuit of the system in order to come up with appropriate control limitations and control targets for the compensation voltage control through the DVR. The control of the DVR is implemented through derived reference load terminal voltages. The proposed control scheme is simple to design. Simulation results carried out by MATLAB with its Simulink and Sim Power System (SPS) toolboxes to verify the performance of the proposed method.

10 Single phase transformer less inverter with ac-coupled inductors to improve the efficiency and reliability of Grid connected PV systems
Parijatha.Arkapalli, T.Santhosh kumar, V.Vijaya Bhaskar

Abstract-The pv systems are designed with transformer for safety purpose with galvanic isolation. However, the transformer is big, heavy and expensive. Also, it reduces the overall frequency of the conversion stage. Generally PV inverter with transformer is having efficiency around 92%– 94% only. To overcome these problems, transformer less PV system is introduced. It is smaller, lighter, cheaper and higher in efficiency. However, dangerous leakage current will flow between PV array and the grid due to the stray capacitance. There are different types of configurations available for transformer less inverters like H5, H6, HERIC, oH5, and Dual paralleled buck inverter.
