Introduction to Crystal Growth Techniques
- B.Subashini , Mrs.Geetha
Abstract
Man had admired crystals for long, as he had appreciated their beauty. The gems and crystals delivered by mother earth have always attracted our mankind, and the belief in the virtues of gems and some minerals dates back to at least two thousand years. The use of gems for ornamental purposes appears to be in practice since the birth of humankind. Today, crystals are the pillars of modern technology. Without crystals, there would be no electronics industry, no photonics industry, no fibre-optic communications, very little modern optical equipment and some very important gaps in conventional production engineering. In the past few decades, there has been a growing interest in crystal growth process, particularly in view of the increasing demand of materials for technological applications (Laudise 1975; Brice1986; Nalwa and Miyata 1996).The significance of crystal growth to electrical engineering, chemistry and physics is illustrated in Figure 1.1. Modern technology requires physicists, chemists, electrical engineers, metallurgists and crystal growers to assist each other at many levels. Crystal growth is a vital and fundamental part of materials science and engineering, since crystals of suitable size and perfection are required for fundamental data acquisition and for practical devices such as detectors, integrated circuits and for other applications.

- S.Anuradha , M.Yegammai
Abstract
We have investigated heat and mass transfer in a steady two-dimensional magneto hydrodynamic viscoelastic fluid flow over a stretching vertical surface with nth order chemical reaction. The two-dimensional boundary-layer governing partial differential equations are reduced to ordinary differential equations by using Nactsheim-Swigert shooting technique with sixth order Runge-Kutta iteration Method. e ordinary differential forms of momentum, energy and concentration equations obtained by local similarity transformation are highly nonlinear. The effects of different flow parameters like magnetic field parameter, Prandtl number, buoyancy parameter, Soret number, Dufour number on velocity, temperature and concentration profiles are plotted and discussed numerically and graphically. Keyword: MHD, Viscoelastic fluid, stretching sheet, Boussinesq approximation, Buoyancy force.×

Introduction to Nonlinear Optics and Crystal Growth Techniques Process
- K. Ezhilarasi , M. Murugan
Abstract
Nonlinear optical property is an important phenomenon in optoelectronics. The frequency conversion of the non linear optical (NLO) material has a significant impact on laser technology, optical communication and optical storage technology. Therefore scientists were very much interested in to discover new NLO crystals. The search of new frequency conversion material was concentrated over the organic materials. But they have often-inadequate transparency, poor optical quality, lack of robustness and low laser damage threshold. Hence recent search concentrates on semi organic materials due to their large nonlinearity, high resistance to laser induced damage, low angular sensitivity and good mechanical hardness.

Computation of Electronic Structure and Ground State Properties of NaZnF3
- A. Johnson Samuel , M. Murugan
Abstract
The electronic structure and the ground state properties of fluoroperovskite compound NaZnF3 in the orthorhombic and cubic phases has been studied by means of self- consistent Tight Binding Linear Muffin - Tin Orbital (TB-LMTO) method. The NaZnF3 crystallizes in the orthorhombic structure at ambient condition and at high temperature it crystallizes in cubic structure. The total energies for the subjected compound were calculated as a function of reduced volume for both orthorhombic and cubic structure. The calculated total energies as a function of volume were fitted to the Birch EOS to obtain the ground state properties. The calculated ground state properties of these compounds are in good agreement with the experimental results. The total density of states and the band structure of NaZnF3 were calculated and are plotted at ambient pressure as well as at high pressure. Between the two structures, orthorhombic structure is found to be stable phase. Cubic NaZnF3 is found to be an indirect bandgap insulator with gap occurring between points. Whereas orthorhombic NaZnF3 is found to be a direct band gap insulator with gap occurring at - points. Keyword: - - -.×

Utilization of a 6U Nanosatellite for Lunar Sampling Mission
- Taavishe Gupta, Sandeep Jangid, Ugur Guven
Abstract
The Moon has been one of the primary driving forces of mankind as it is the closest object to Earth. Naturally, it creates a lot of interest and many missions have been conducted before to study the Moon. Unfortunately, the cost of such missions has been prohibitive for more global engagement in lunar research. However, now with the advancing technology, it has become very evident to use nanosatellite technology to send a mission to the moon as launching and deploying a nanosatellite is far easier and less costly as compared to a full size satellite or a full size stellar probe. Thus, this paper discusses a case study of a Lunar Mission which utilizes a 6U Nanosatellite for a Lunar Sampling Mission.

NYMBLE: Blocking Misbehaving Users in Anonymizing Networks
- R.Ravikumar, J.Ramesh Kumar
Abstract
Nymble, a system in which servers can blacklist misbehaving users, thereby blocking users without compromising their anonymity. Our system is thus agnostic to different servers’ definitions of misbehavior servers can blacklist users for whatever reason, and the privacy of blacklisted users is maintained. In pseudonymous credential systems users log into Web sites using pseudonyms, which can be added to a blacklist if a user misbehaves. Anonymous credential systems employ group signatures. Basic group signatures allow servers to revoke a misbehaving user’s anonymity by complaining to a group manager. Anonymizing networks such as Tor allow users to access Internet services privately by using a series of routers to hide the client’s IP address from the server. The success of such networks, however, has been limited by users employing this anonymity for abusive purposes such as defacing popular Web sites. Web site administrators routinely rely on IP-address blocking for disabling access to misbehaving users, but blocking IP addresses is not practical if the abuser routes through an anonymizing network. As a result, administrators block all known exit nodes of anonymizing networks, denying anonymous access to misbehaving and behaving users alike. a secure system called Nymble, which provides anonymous authentication, backward unlinkability, subjective blacklisting, fast authentication speeds, rate-limited anonymous connections, revocation auditability that is the users can verify whether they have been blacklisted, Nymble thus represents a practical solution for blocking misbehaving users of anonymizing networks. The user must first contact the Pseudonym Manager (PM) and demonstrate control over a resource; for IP-address blocking, the user must connect to the PM directly. We assume the PM has knowledge about Tor routers, and can ensure that users are communicating with it directly. Pseudonyms are deterministically chosen based on the controlled resource, ensuring that the same pseudonyms always issued for the same resource. Keyword: Nymble, anonymizing networks, symmetric cryptography, blocking.×

Control Cloud Data Access Privilege and Anonymity with Fully Anonymous Attribute-Based Encryption
- R.Ravikumar , C. Sivasamy
Abstract
Cloud computing is a revolutionary computing paradigm, which enables flexible, on-demand, and low-cost usage of computing resources, but the data is outsourced to some cloud servers, and various privacy concerns emerge from it. Various schemes based on the attribute-based encryption have been proposed to secure the cloud storage. However, most work focuses on the data contents privacy and the access control, while less attention is paid to the privilege control and the identity privacy. In this paper, we present a semi anonymous privilege control scheme Anony Control to address not only the data privacy, but also the user identity privacy in existing access control schemes. Anony Control decentralizes the central authority to limit the identity leakage and thus achieves semi anonymity. Besides, it also generalizes the file access control to the privilege control, by which privileges of all operations on the cloud data can be managed in a fine-grained manner. Subsequently, we present the Anony Control-F, which fully prevents the identity leakage and achieve the full anonymity. Our security analysis shows that both Anony Control and Anony Control-F are secure under the decisional bilinear Diffie – Hellman assumption, and our performance evaluation exhibits the feasibility of our schemes. Keyword: Anonymity, multi-authority, attribute-based encryption.×

Comparative Study and Performance Analysis of Copper, Aluminium and Cuprobraze Radiators Using Flow Simulation Software
- R.K Jaya kumar, T.Ashokkumar
Abstract
Cooling system in an automotive vehicle plays an important role in the engine performance. It dissipates excessive heat and maintains the performance of an engine at an optimum level. Size of the radiator mainly depends on heat load and availability of space. In this paper, an attempt has been made to examine the performance of radiators namely copper, aluminium and Cuprobraze employed in various commercial vehicles. Specifications of copper radiator and validation of numerical analysis were identified. After modifying the material properties of a radiator, performance analysis have been carried out using fluid flow software, which is fully integrated in solidworks for computing fluid flows. The result obtained from the analysis is commendable and this method may be taken as an effective approach for the prediction of heat transfer in radiators. Though aluminium has noted to perform better than copper and Cuprobraze, but it has limitations such as irreparability, non recyclability. This paper proposes an alternative solution for existing aluminium radiator with suitable cuprobraze radiator to provide required cooling effect to the engine, thereby overcoming the drawbacks of the radiator.

M-Privacy for Collaborative Data Publishing By Using Heuristic Approach
- Ms. Sheetal D. Shahare , Mr.Sachin Barahate
Abstract
According to the survey Maintaining and preserving privacy has become more significant problem. We consider the collaborative data publishing problem for anonymizing horizontally partitioned data at multiple data providers. We consider a new type of “insider attack” by colluding data providers who may use their own data records (a subset of the overall data) to infer the data records contributed by other data providers. For M-privacy several anonymization techniques have been used such as bucketization, generalization, perturbation which does not prevent privacy and fail to maintain a privacy constraint and results in loss of information. So we consider the collaborative data publishing for anonymizing horizontally partitioned data at multiple data provider. First, we provide the notion of m-privacy, which give guarantees that the anonymized data satisfies a given privacy constraint against any intruder attack. Then we present heuristic algorithms with effective pruning strategies and adaptive ordering techniques for efficiently checking m-privacy for a set of records i.e to breach the privacy. Here intruder are also detected which try to breach the privacy. This technique shows the better utility and efficiency than the previous techniques.We develop a truthful and efficient M-privacy for collaborative data publishing by using pruning strategy and providing them anonymized data in case of emergency.

Abstract
Throughout the world, the disposal of used tires is a major environmental problem causing environmental hazards such as breeding ground for mosquitoes, producing uncontrolled fire and they are contaminating the soil and vegetation. Therefore, there is an urgent need to identify alternative outlets for these tires, with the emphasis on recycling the waste tire. Concrete is an excellent structural material and considered as essential for the modern civilization and human society. Now, the use of waste tires in concrete has become technically feasible and the concrete is being considered as light weight concrete. This study reviews the feasibility of using waste tires in the form of chips with different sizes in concrete to improve the strength as well as protecting the environment. In this study, we outline the use of rubberized concrete in structural and non-structural members and show how it is suitable for the concrete, its uses, barriers and benefits to future study.

- Gunupuru Tulasi , Prema Kumar Navuri
Abstract
Increasing demand on conventional distribution system emerges the distributed energy sources to place near the consumer premises to maintain the reliability of supply. DG also includes the benefits of reduced power loss, improved voltage profile and also reduced transmission and distribution costs. Placement of DG sources have some impact on existing distribution system. The impacts may be technical, economical or environmental. In this paper we have introduced technical and economic benefits of DG. Planning of DG size and location is necessary to obtain the satisfactory performance. In this paper improved particle swarm optimization(IPSO) and global harmony search(GHS) algorithms are used to minimize the objective function. In these methods of optimization, DGs are randomly placed at each bus and size is obtained. Then these results are compared with previous results and optimal location and sizes corresponding to optimal location are obtained. Here, objective function is the function of impact indices on distribution system due to placement of DG . Forward-backward sweep method is considered for studying the load flow of radial distribution system over various techniques available.

Automatic Image Annotation Using Modified Multi-label Dictionary Learning
- Sreedhanya.S , Chhaya.S.Pawar
Abstract
Automatic image annotation has attracted lots of research interest, and effective method for image annotation. Find effectively the correlation among labels and images is a critical task for multi-label learning. Most of the existing multi-label learning methods exploit the label correlation only in the output label space, leaving the connection between label and features of images untouched. In image annotation, a semi supervised learning which incorporates a large amount of unlabeled data along with a small amount of labelled data, is regarded as an effective tool to reduce the burden of manual annotation. But some unlabeled data in semi-supervised models contain distance that negatively affects the training stage. Outliers in the method can be over-fitting problem especially when a small amount of training data is used. In this paper, proposing an automatic image annotation method called modified MLDL with hierarchical sparse coding for solving these problems. This method prevents the over-fitting associated with the semi-supervised based approach by using sparse representation to maximizing the correlation between the data. Apply a Tree Conditional Random Field to construct the Hierarchical structure of an image. The result will be multi-label set prediction of a query image and semantic retrieval of images. Experiment results using LabelMe datasets and Caltech datasets confirms the effectiveness of this method. Keyword: Automatic image annotation, MLDL, Sparse representation, Semi-supervised learning (Semi CCA), Hierarchical representation.×

Speech Enhancement by using Ideal Binary Mask
- Priyanka V. Patil ,Vikram. A. Mane
Abstract
Communication via speech is one of the essential functions of human beings. Humans possess varied ways to retrieve information from the outside world or to communicate with each other. Three most important sources of information are speech, images and written text. For many purposes, speech is more efficient and convenient way. Speech not only conveys linguistic contents, but also communicates other useful information like the mood of the speaker.In speech communication systems the quality and intelligibility of speech is most important for easy and accurate exchange of information. In realistic listening situations, speech is often contaminated by various types of background noise. The presence of background noise degrades the quality as well as intelligibility of speech.This degradation of speech by noise creates problems not only for just interpersonal communication but more serious problems in applications in which decision or control is made on the basis of speech signal. So, there is need to develop a new method for speech enhancement which will improve quality as well as intelligibility of the speech. This paper presents method of speech enhancement by using Ideal Binary Mask. This is a simple method for enhancing the speech with the objective to eliminate the additive noise present in speechsignal and restore the speech signal to its original form with improved quality as well as intelligibility of speech.

Lung Cancer Detection Using Mean Shift Clustering Algorithm and Bayesian Decision Theory
- V.Sowmya , Dr.Judith Justin
Abstract
Early detection of lung cancer is a demanding problem due to both the structure of the cancer cells and the staining method employed in the formulation of the sputum cells. The manual analysis of the sputum sample is time consuming and inaccurate due to overlapping of the cells. Computer Aided Diagnosis (CAD) system helps to detect cells accurately, thereby improving the chances of survival of the patient. In the proposed study, Wiener filter is used to denoise the image and the quality metrics such as Peak Signal to Noise Ratio (PSNR) and Root Mean Squared Error (RMSE) are used to assess the performance. The sputum cells are segmented using Mean Shift Clustering Algorithm and to extract the homogeneous tissues in the image. Bayesian Decision Theory classifies images as normal or abnormal.

- K. Uma , V.Sowmya , S.Gowri
Abstract
Automatic wheelchair cum bed with voice control mechanism for paraplegic patients is an innovative idea in the field of rehabilitation. For precise control and accurate movements, the joystick and voice control mechanisms are used by the patients. Voice controlled movement will be extremely helpful to someone who might lack the physical ability to move both their legs. The wheelchair can also be customized as a bed by stretching it. This will help the paraplegic patient to lie down without an auxiliary support. The hardware set up will provide the necessary mechanical movements like forward, left, right and height. By means of ultrasound sensor, the obstacle can be detected and displayed on the LCD. The patients with paraplegia find it very difficult to sit continuously in the same position as it can develop back pain and muscle cramps. Thus as a preventive measure, a massaging system for the lumbar region is incorporated in this wheelchair. Keyword: Wheel chair, Joy stick, paraplegia.×

Multiple Image Sharing Scheme Using Visual Cryptography for color and Gray Level Image
- Rajeev Kumar Sao , Mr. Prabhakar Sharma
Abstract
Information is increasingly important in our daily life. Information gets more value when shared with others. Due to advances in technologies related to networking and communication, it is possible to share the information like audio, video and image easily. It may give rise to security related issues. Attackers may try to access unauthorized data and misuse it. One of the variants of the visual cryptography is multiple image sharing scheme of visual cryptography in which more than one images are hidden and shared between the receiver and the transmitter securely. In this thesis, a multiple sharing scheme is presented for color image which is designed to hide 4 secret images. With slight modification in this scheme, this scheme can be extended to share more than 4 images. Keyword: visual cryptography scheme (VCS), pixel expansion, OR operation security, accuracy, computational complexity.×

Path Loss Study of Lee Propagation Model
- S.Karthika
Abstract
Channel properties has high impact on the development of wireless communication systems. Unlike wired channels are stationary and predictable, radio channels are extremely random and don’t offer easy analysis. A Radio Propagation Model (RPM), is an empirical mathematical formulation for the characterization of radio wave propagation as a function of frequency. In wireless communication, path loss propagation models are mandatory for proper planning, interference estimations, frequency assignments and cell parameters which are the basic for network planning process. Propagation models that predict the mean signal strength for an arbitrary transmitter-receiver (T-R) separation distance which is useful in estimating the radio coverage area of a transmitter are called large-scale propagation models, since they characterize signal strength over large T-R separation distances. In this paper, the large-scale propagation performance of Urban, Suburban and Open Area has been compared using Lee Model by varying Mobile Station (MS) antenna height, Transmitter-Receiver distance and Base Station (BS) antenna height, considering the system to operate at 900 MHz. Through the MATLAB simulation it is turned out that the Open Area shows the better performance than that of the other areas.

- Puspraj Singh , Gaurav Verma , Dr. L.P. Singh
Abstract
Spur gear is a gear which is used to transmit power from one shaft to another shaft. At the time of power transmission several types of stresses presented on gear while designing. The bending stress is considered as the main cause of failure during the transmission of power. In the present study bending stress can be calculated by using AGMA and ANSYS. CATIA V5R19 is used for designing of gear. Then file is saved in IGES format and imported in ANSYS 15.0 where it analyzed. The major purpose of this study has to investigate the stress induced in a spur gear tooth parameter. At the end AGMA and ANSYS results has been compared with each other.

Hygroscopic and Rheological properties of sustainable Dalbergia sissoo Wood Flour on Recycled/Virgin Polypropylene Composites with/without MAPP
- Gaurav Verma, Dr .L.P. Singh, Anil Kumar Yadav , Dr .P.B.Patel
Abstract
This study scrutinizes, the influence of wood sawdust (Dalbergia sissoo) as filler on hygroscopic and rheological properties of composite produced by using it with recycled/virgin polypropylene (PP). In this research, wood sawdust of 200-250µm was compounded in the form of pallets using twin screw extruder for which the composites of PP matrix 80, 70, 60 and 50 wt% was used. These pallets were then fabricated into the specimen by injection moulding method with altering formulations based on the synthetic polymer type (PP), synthetic polymer form (recycled and virgin), wood sawdust content and inclusion of coupling agent(MAPP). The result exhibits that recycled polypropylene (RPP) based WPCs shows better water absorption and thickness of swell than composite based on virgin polypropylene (VPP). The maleated polypropylene (MAAP) improves the dimensional stability of the WPCs remarkably when incorporated in small concentration of 3-5 wt% in the formulations. The Scanning electron microscopy (SEM) analysis of tensile-fractured surfaces of the specimen clarifies the aftermath of reprocessing in WPCs and improvement in interfacial bonding due to presence of the coupling agent (MAPP).

- Kayode Hassan Lasisi, Olanrewaju Adebayo Ojomo
Abstract
Energy is one of the most fundamental of human needs and it drives human life, and is extremely crucial forcontinued human development. This paper presents the findings of a research that was carried out to determine the generation of biogas from cow dung using a low cost fabricated bio-digester. A cylindrical drum of capacity 100 litres was used as bio-digester and fed with 40 kg of cow dung mixed with warm water in proportions of 2:1. Also, calcium hydroxide (Ca (OH)2) was incorporated into the experiment to remove the carbon(iv)oxide from the biogas produced and termitic enzymes solution to acceleratethe biogas yield. Results from this study shows that the digestion of cow dung resulted in an appreciable biogas yield. Comparing this result with sample of cow dung mixed with warm water in the ratio 1:1 and taking into account the natural state of the waste when collected for experiment, it is of considerable range when compared with the standard values. Ultimately, digestion of cow dung is one way of addressing the problem of insufficient energy supply in developing countries.
