 Abstract

This paper proposes a fuzzy logic controller for wind energy conversion system based on permanent magnet synchronous generator and pulse width modulated current source converter. Integration in the grid for this type of generator requires a converter. Here type of converter is pulse width modulated current source converter (PWM-CSC). Power generated by PMSG is modified according to the wind velocity and load profile by the converter. The fuzzy logic controller which is based on human expertise knowledge is employed to overcome all the setbacks witnessed in all the other controllers. Fuzzy logic has the features of simple concept, easy implementation, and computationally efficient. The function of FLC is to track the generator speed with the reference speed for maximum power extraction at variable speeds.

Harmonic is one of the main factors that degrade the signal quality and this is a serious problem faced by the power amplifier in its working. These are introduced into the power amplifier due to the nonlinearities of the active element such as transistor in the power amplifier. Therefore the mitigation of harmonics is essential under these circumstances. This paper presents the design of a Chebyshev low pass filter using LC components for the mitigation of harmonics for a frequency range 30-50MHz. Advanced Design System is used for simulation purpose. The obtained results show that Chebyshev low pass filter rejects the harmonic frequencies successfully with a stopband rejection of -24dB.

Data mining is the process of extracting knowledge from data. That knowledge is usually related with relationships between variables and/or observations and patterns likes clusters of observations. Discovering hidden patterns from the web logs is an upcoming research area. Predictions need to keep track of history data to analyze the usage behavior of the users. Web usage mining consists of pre-processing, pattern discovery and pattern analysis. Web prediction is a classi?cation problem which attempts to predict the most likely web pages that a user may visit depending on the information of the previously visited web pages. System emphasis is on the prediction of user behavior using web log ?le. This approach requires user session identi?cation, clustering the sessions into similar clusters and developing a model for prediction using the current and earlier accesses. The system uses pre-processing of web log, hierarchical clustering technique and data mining algorithm for prediction.

Security has turned into a significant issue when the uses of huge information are drastically developing in cloud processing. The advantages of the execution for these rising innovations have enhanced or changed administration models and enhance application exhibitions in different points of view. In any case, the surprisingly developing volume of information sizes has too brought about numerous difficulties day by day. The execution time of the information encryption is one of the difficult issues amid the information preparing and transmissions. Numerous present applications surrender information encryptions so as to achieve a supportive execution level companioning with protection concerns. In this paper, we focus on protection and propose a novel information encryption approach, which is called Sensitive Data Classification & Selective Encryption (SCSE). Our proposed approach intends to specifically scramble information also, utilize protection characterization techniques under planning requirements. This approach is intended to boost the security assurance scope by utilizing a specific encryption system inside the required execution time necessities. The execution of PCSDE has been assessed in our analyses, which gives the verification of the security upgrade.

Abstract: This paper explores the historical and social context of population of genetic research conducted in India by focusing on a study by Kammara Rajyalakshmi which aimed to reconstruct Indian for gated (neglected ,omit) Culture and there people who worked hard in their life because they were the part of their mother land they were called Rajpuths they were treated as the wonderful blessed saints who were kshatriyas(and allowed to do all the activities of the saints in the temples it was an honors to them ) but what is the condition today.?. First, it considers the agendas and modes of thinking about Indian populations and the caste system on which this study appears to be based. Second, it reflects on the implications of these studies they who presented in kammar .Rajya lakshmi findings. India is a country with many traditions and languages all over the world it is famous for its tradition, different languages, different people, different landscape and culture it is not only bio-diversity but also a sovereign country. Here I suggest that while mapping Indian population appears to have inherited many of the problems characrstics of people as genetic research condition in India the specificity of the research in India involves a peculiar interplay of the past colonial pursuit of genomic sovereignty desire by the Indian state to become a player in the global redone of biodiversity and age old discourse naturalizing casts and regime; difference my argument is that, although the study offered conceptual space for a wide range of interpretations it has a strong potential not just for naturalizing caste and regional differences in India but also for pathological government without necessarily bringing tangible health care benefits in the foreseeable feature.

 Abstract

In the current scenario, companies and people are outsourcing the database to achieve useful administrations and applications of minimum effort. These are buried in the cloud server, which is beyond the control of the owner of the data. SQL queries require a secure database schema for their undeniable operation, but this finally causes a spill of privacy in the cloud server. For the investigation of numerical range (>, <, etc.) they forget to provide an adequate security insurance. A part of the difficulties faced are the loss of privacy of statistical attributes, access patterns, etc. In the same way, a larger number of queries will release more information to the cloud server. Therefore, with regard to these issues, numerous researchers have done numerous works. Some of these research works have been analyzed in the best possible ways to achieve the desired level of privacy preservation in the case of cloud computing. Some of the works studied are fuzzy logic, range queries, the order of CryptDB that preserves the encryption and the architecture of several clouds.

 Abstract

Cement is the most expensive constituents of concrete. Over 5% of global CO2 emission is attributed by cement production. The use of scrap tyre rubber in the preparation of concrete has been thought as an alternative disposal of such waste to protect the environment. consequently, it is required to find substitute materials to reduce the cost of concrete. In this work, alternate source for cement as rice husk ash (RHA) and coarse aggregate as waste tyre rubber is tried. In the current experimental analysis, the M20 grade concrete is preferred as the reference concrete specimen. A comparative study is done on properties of concrete when cement and aggregate are partially replaced by rice husk ash and waste tyre rubber. Percentage replacement of cement and coarse aggregate with RHA and tyre rubber are replaced at 0%, 5%, 10% and 15% in a mix of M20 grade of concrete. The compressive strength is found out at 7 and 14 days. The strength is compared with control concrete and the optimum % of replacement of RHA and rubber is found out. The objective of this project is to investigate the use of rubber pieces as coarse aggregate and RHA as cement in the concrete. Concrete is tested with varying percentages of rubber and RHA from 0 to 15% of normal aggregates. Compressive strength of concrete, impact value, abrasion value, slump value is measured and comparative analysis is made. Based on the analysis of results, the conclusions that can be made are: 1.The workability of concrete decreased as the percentage of rubber and RHA increased. 2. Lack of cohesiveness and proper bonding between rubber and cement causes shear slump. 3. Compressive strength of normal concrete is higher compared to rubberized and RHA concrete.4. Replacement of rubber reduces the weight of the concrete. 5 compressive strength decreases as the percentage of replacement increases.

Chronic kidney disease (CKD) is a major cause of cardiovascular morbidity and mortality and is considered as a significant public health problem that places a burden on global healthcare resources. The observation is that small reductions in the decline in renal function early in the disease process can provide marked benefits later, in terms of delaying progression to renal replacement therapy, suggests that substantial benefits can be gained from the early identification and treatment of individuals at risk. In order to develop effective strategies to identify such individuals and delay or prevent disease progression, a comprehensive understanding of the complex interplay between risk factors influencing the disease process is required to be observed. This study was undertaken to assess the major risk factors associated with CKD1
