P.Ramesh Babu, Y.Chitti Babu, Dr.P.Harini
Here We Proposed A New Data-Hiding Method Based On Pixel Pair Matching (PPM). In This Paper The Basic Idea Of PPM Is To Use The Values Of Pixel Pair As A Reference Coordinate, And Coordinate Search In The Neighborhood Used To Set Of This Pixel Pair According To A Given Message Digit. The Pixel Pair Is Then Replaced By The Searched Coordinate To Conceal The Digit.(EMD)Exploitedmodificationdirection(EMD) And Diamond Encoding (DE) Are Two Data-Hiding Methods Proposed Recently Based On PPM. Then The Maximum Capacity Of EMD Is 1.161 Bpp And DE Extends The Payload Of EMD By Embedding Digits In A Larger Notational System.This Is The Proposed Method Offers Lower Distortion Than DE By Having High Compact Neighborhood Sets And It Will Also Accepting Embedded Digits In Any Representative System. Then It Will Be Compared With The (OPAP)Optimal Pixel Adjustment Process Method, Then This Method Always Has Lower Distortion For Various Payloads. Experimental Results Reveal That The Proposed Method Does Not Only Provides Performance Better Than Those Of OPAP And DE, But Also Is Secure Under The Detection Of Some Well-Known Steganalysis Techniques

The creep nature of metallic spur gear results in the deficiency because of the deformation of teeth when pressure angle of 20 acting on it. At the replacing points of tooth between driving and driven the disturbances such as in-evitable random noise, elastic deformation and manufacturing error, alignment error in assembly all these together causes the high level of gear vibration and noise and leads to loss in efficiency. The main motto is to reduce the deformation of teeth, by replacing the metallic cast iron gear with Nylon gear and proved that the deformation of Nylon gear is less compared to metallic and polycarbonate. Since the deformation is less the loss in efficiency is also less compared to metallic gear.

Stress Analysis of Splice Joint of the Aircraft Bottom Wing Skin by Finite Element Method
A.Rukesh Reddy, P. Ramesh, B. Siddeswara rao
This paper investigates the maximum stress concentrated part of the splice joint of an aircraft bottom wing skin due to tensile loading. Wings are the aerofoils attached to each side of the fuselage to produce lift force. Joints are inevitable in any large structure like an aircraft wing. Splicing is normally used to retain a clean aerodynamic surface of the skin for most of the aircraft structure. This analysis considers the wing box with a bottom skin splice joint. The wing box comprises of two spar beams, three ribs, stiffeners covered with skin plate. In this paper the chord-wise splicing of wing skin is considered for a detailed analysis. The splicing is multi row riveted joint under the action of tensile in plane load due to wing bending. The stress analysis of the joint is carried out to compute the stresses at rivet holes due to By-pass load, bearing load and secondary bending. The splice is optimized to minimize the rivet hole local stress. A finite element analysis is carried out to evaluate the stresses. Analyses were performed by MSC PATRAN and NASTRAN software.
Keywords:stress analysis, splice joint, wing skin and rivet holes.

Cloud Information Accountability Framework for Auditing the Data Usage in Cloud Environment
Cloud computing enables highly scalable services to be easily consumed over the Internet on an as-needed basis. A major feature of the cloud services is that users' data are usually processed remotely in unknown machines that users do not own or operate. While enjoying the convenience brought by this new emerging technology, users' fears of losing control of their own data (particularly, financial and health data) can become a significant barrier to the wide adoption of cloud services. To address this problem, in this paper, a novel highly decentralized information accountability framework to keep track of the actual usage of the users' data in the cloud. In particular, an object-centered approach that enables enclosing our logging mechanism together with users' data and policies. Leverage the JAR programmable capabilities to both create a dynamic and traveling object, and to ensure that any access to users' data will trigger authentication and automated logging local to the JARs. To strengthen user's control, provide distributed auditing mechanisms. Extensive experimental studies that demonstrate the efficiency and effectiveness of the proposed approaches.

Nguyen An Son, Pham Dinh Khang, Nguyen Duc Hoa,
Nguyen Xuan Hai,Dang Lanh
The experiment was setup on the 3rd horizontal channel of Dalat nuclear reactor. The sample
was activated by thermal neutron which is about 106 neutron/cm2/s. The gamma-gamma system is used
to collect experimental data. The Summation of Amplitude Coincidence Pulses method (SACP) treats
the experiment data. In this paper, the gamma cascades based on 48Ti(nth, 2 gamma)49Ti reaction.
Event – event coincidence method got relative intensity, gamma ray energy directly, and the gamma
cascades collected directly as well. Since then, the transition probabilities and some intermediate
quantum characteristics are splitted and determined. The single particle model is applied to treat the
results. The advantage of this method is that it allows determining a pair of the transitions and the
intermediate levels directly. The branching ratios of such gamma transitions are used to calculate the
partial gamma width, the total gamma width, lifetime of level. Besides, the transition strengths have
been calculated for gamma transitions

The Effect Of Water Solubles On The Hygroscopicity Of Urban Aerosols
B. I. Tijjani
In this paper, the author extracted some microphysical and optical properties of urban aerosols from OPAC by varying the concentrations of water soluble at the spectral range of 0.25μm to 2.5μm and eight relative humidities (RHs) (0, 50, 70, 80, 90, 95, 98, and 99%).The microphysical properties extracted were diameters, volume mix ratio, number mix ratio, mass mix ratio and refractive indices while the optical properties are optical depth and asymmetric parameters all as a function of RHs. Using the microphysical properties, hygroscopic growth factors of the mixtures and their effective refractive indices were determined while using optical depth we determined its relation with RHs, the enhancement parameters and Angstrom parameters. The hygroscopic growths and enhancement parameters were then parameterized using some models to determine their relationship with RHs. The data fitted the models very well. The angstrom coefficients show that the mixtures havebi-modal type of distribution with the dominance of fine mode particles and the mode sizes increase with the increase in water soluble concentrations and RH.The relation of optical depth with RH shows improvement with the increase in water soluble but decreases with the increase in wavelengths.The asymmetric parameters show that hygroscopic growth enhances forward scattering at smaller wavelengths
Efficient Solution of Constraint Satisfaction Problems by Equivalent Transformation
In many conventional programming languages, programs are constructed from built-in data structures and built-in constraints. Due to the limitation of the expressive power, the computation may become very inefficient when they are used to solve large and complicated problems. In order to overcome the difficulty, we adopt a computing framework of "problem solving based on equivalent transformation (ET)." In this framework, a problem can be solved by simplifying declarative descriptions of the problem on the equivalent transformation basis, and the correctness of computation can be guaranteed. Furthermore, users can easily introduce new various data structures and constraint-solving rules necessary for the improving of the constraint-solving algorithms. In this paper, we show that "problem solving based on equivalent transformation" is useful to avoid the combinatorial explosion when solving large constraint satisfaction problems

Harmonic Filter Design for Hvdc Lines Using Matlab
P.Kumar , P.Prakash
This paper presents harmonic filter design for HVDC lines using MATLAB version R2009a.Non-linear devices such as power electronics converters can inject harmonics alternating currents (AC) in the electrical power system. The number of sensitive loads that require ideal sinusoidal supply voltage for their proper operation has been increasing. To maintain the quality limits proposed by standards to protect the sensitive loads, it is necessary to include some form of the filtering device to the power system. Harmonics also increases overall reactive power demanded equivalent load. This paper deals with the design of three phase filter banks connected in parallel to achieve optimal control for harmonic elevation problems

An Automated Image Segmentation Scheme for Iris Recognition
Dr. G. Saravana Kumar, J. Munikrishnan, Manimaraboopathy
The paper proposes an automated segmentation system, which localize the iris region from an eye image and also isolate the eyelid, eyelash as well as the reflection regions. This Automatic segmentation was achieved through the utilization of the circular Hough transform in order to localize the iris as well as the pupil regions, and the linear Hough transform has been used for localizing the eyelid occlusion. Thresholding has been employed for isolating the eyelashes as well as the reflections. Now, the segmented iris region has got normalized in order to eliminate the dimensional inconsistencies between the iris regions. This was achieved by applying a version of Daugman's rubber sheet model, in which the iris is modeled as a flexible rubber sheet, which is unpacked into a rectangular block with constant polar dimensions. Ultimately, the iris features were encoded by convolving the normalized iris region with the 1D Log-Gabor filters and phase quantizing the output to produce a bit-wise biometric template. For metric matching, the Hamming distance has been chosen, which provides a measure of number of disagreed bits between two templates
DWDM Link with Multiple Backward Pumped Raman Amplification
Awab Fakih, Santosh Jagtap, Shraddha Panbude
Faced with the challenge of dramatically increasing capacity while constraining costs, carriers have two options either to install new fiber or increase the effective bandwidth of existing fiber. The technology of dense wavelength-division multiplexing (DWDM) has recently resulted in a considerable increase in the transmission capacity of fiber-optic communication systems up to several terabits per second. The further improvement of the transmission capacity of such systems can be achieved through the expansion of the spectral range of WDM transmission toward the short-wavelength region. Therefore in this report we have proposed and investigated the new trends and progress of fiber Raman amplification for dense wavelength division multiplexing photonic communication networks. Forty individual channels carrying PRBS data are transmitted over a 50 km length of ITU-T G.652 single mode dispersive fiber. The design objective is to utilize distributed Raman amplification to compensate for the link attenuation thereby effectively increasing the inter-EDFA span in a longer-haul link.

Purneet Kaur , Jaspreet Kaur
Fingerprints are the most used biometric feature for the person identification. During research it has been observed that there are number of approaches has been implemented for recognition of fingerprints. Different algorithms and techniques have been used for enhancement purpose, minutiae extraction and for matching. In this thesis work a novel technique to enhance our results by using the combination of genetic algorithm and neural network. As we know that both techniques are the world's best techniques. Genetic algorithm is used for the extraction of minutiae and neural network is used for the recognition of a fingerprint. Firstly, fingerprint image has been enhanced using histogram equalization process so that our algorithm also capable of predicting good results even for dull or low intensity images too. Then Morphological Image Processing operations using MATLAB 2011b has applied for thinning the lines up to the predefined extent so that it will not further destroy or harm our structure of the image. After that we proceed towards predicting of discontinuities using Genetic Algorithm approach based upon nth last segment. Here genetic algorithm is used to find the best possibility for each discontinues segment in an image. Lastly Enhanced image has fed to NN (neural networks) based trained system to diagnose and match finger print with data set. Several features will be used to train the network so that precision will be made in recognition of finger print.
Content Based Medical Image Retrieval – Performance Comparison of Various Methods
Harishchandra Hebbar, Niranjan U C, Sumanth Mushigeri
Present healthcare system calls for standardization and interoperability of images acquired by various equipment manufacturers. The healthcare system is also not limited to a single super-specialty hospital where state of the art machines and excellent physicians are available but should also these services need to be available in remote places too. Nowadays, number of images acquired by the hospitals is increasing due to the various modalities available to identify accurately the cause of the deceases. This results in more number of medical images being stored in the database in hospitals. The interpretation of these medical images becomes even more critical, as it may contain the information which cannot be perceived by human eye. Therefore the images need to be annotated appropriately while it is stored so that, retrieval of the images of interest can be done quickly. The manual annotation is very cumbersome process when large number of images is involved in the retrieval process. Hence it is necessary to have an efficient Content Based Image Retrieval System which is user friendly and user definable in terms of speed and Precision

Direct Methodfor Finding an Optimal Solution for Fuzzy
A.Srinivasan , G. Geetharamani
In this paper we shall study fuzzy transportation problem, and we introduce an approach for solving a
wide range of such problem by using a method which apply it for ranking of the fuzzy numbers. Some of
the quantities in a fuzzy transportation problem may be fuzzy or crisp quantities. In many fuzzy decision
problems, the quantities are represented in terms of fuzzy numbers may be triangular or trapezoidal. Thus,
some fuzzy numbers are not directly comparable. First, we transform the fuzzy quantities as the cost,
coefficients, supply and demands, in to crisp quantities by using Robust's ranking method  and then by
using the classical algorithms we solve and obtain the solution of the problem. The new method is a
systematic procedure, easy to apply and can be utilized for all types of transportation problem whether
maximize or minimize objective function. At the end, this method is illustrated with a numerical example
In this paper we consider some polynomials having no zeros in a given region. Our results when
combined with some known results give ring –shaped regions containing a specific number of zeros of

Simple Domestic Air Conditioning by using the Ice Thermal Storage Capacity
Mohammed Hadi Ali
In this paper, a special design of an experimental rig was used to study and evaluate the performance of using the ice thermal storage capacity for cooling purpose. Nowadays ice thermal storage system is mostly used because it is practical due to the large heat of fusion of ice to change into water. Thermal storage techniques have provided opportunities to store cooling energy in ice when the power price is relatively low.
The experimental rig that was built is a simple domestic air conditioning prototype that can be used to cool small spaces with ice bank which are prepared for this purpose.
Encouraging results were obtained in this paper where two different air flowrate was used to compare between them; it was found that the performance of using the ice storage capacity is effective in which the coefficient of performance (COP) is relatively high compared to a conventional air conditioning. The results showed that the COP for higher air flowrate is lower than the COP for lower air flowrate due to lower power consumed by the system. And the outlet temperature for the higher air flowrate is higher than the outlet temperature for the lower air flowrate due to the more time of contact between the air and the ice banks.
As a conclusion we found that the ice storage capacity process is an effective process of using a chiller or refrigeration plant to build ice during off-peak hours to serve part or the entire on-peak cooling requirement

Marketing strategy of e-business should be adjusted to ensure that the customer is ready to make transaction online. This adjustment is primarily intended to foster customer trust related to privacy and economic risk. E-Trust in B2C e-commerce is more difficult to realize than an offline business. Gaps in e-Trust still exist, how the service without face to face interaction can logically satisfy. The perceptions of e-Service Quality can grow through technology readiness as well as technology acceptance, but e-Trust is more decisive in shaping of the service quality perception. This study aims to discover the customer's perspective on e-Service Quality and to analyze its relations with e-Satisfaction and e-Loyalty. Text corpus of satisfied customer review from the online store is used as the unit of hermeneutics analysis to reveal meaningful reviews. Purposive text sampling with detail in content and context is used to obtain a complete answer to the research question. MAXQDA11 software is used for the configuration analysis process on the connectivity among themes. The perspectives of e-Service Quality are discovered through Fun Shopping theme which is determined by: shopping experience, ease shopping, shopping problem handling and functional satisfaction. Customers' satisfaction perspective is the emotional e-Satisfaction through the emotional satisfaction in online shopping and the delight from family values. The fellow care and special attention are the value delivered by the company. Perspectives on e-Loyalty drawn from Loyal to Each Other: customer loyalty commitment, customer loyalty proof, and customer service staff dedication to serve. The perspectives of e-Loyalty is determined by the e-Trust which is reflected from the themes of mutual trust (Trust Each Other). That is customer recognition to customer service team performance and recognition of the company's reputation offset with the company's trust to the customer.

Estimation of Stress- Strength Reliability model using finite mixture of exponential distributions
In this paper considered a situation where stress and strength follow finite mixture of exponential distributions to find the reliability of a system. It has been studied when stress follow exponential distribution and strength follow finite mixture of exponential distributions and both stress-strength follow the finite mixture of exponential distributions. The general expression for the reliability of a system is obtained. The reliability is computed numerically for different values of the stress and strength parameters. We estimate the parameters of the reliability stress-strength models by the method of maximum likelihood estimation. The role of finite mixture of exponential distributions is illustrated using a real life data on time to death of two groups of leukaemia patients.
