 Abstract

Steganography is the hiding of a secret message within an ordinary message and the extraction of it at its destination. Steganography is the word derived from Greek. Stego means hiding, graphy means writing. It is the science of embedding information into the cover image viz., text, video and image without causing statistically significant modification to the cover image. If the selected image is color image, then convert the image into pixels and the pixels into cells. Read each pixel and generate the color code for that pixel. Here we use LSB(least significant bit) technique to hide the message into the image. LSB data hiding technique does not affect the visible properties of the image. For using LSB technique, we first convert the color code into binary language. Now by using LSB technique, we change the least significant bit value for the binary code generated before. So after changing the least significant bit value whatever value we get, for that number we see the color code and then we hide our text in that pixel which will contain that particular color code. Repeat this process until we hide our full message.

 Abstract

A bug report is typically assigned to a single developer who is then responsible for fixing the bug. Development a new bug firstly is found by developers or users. Then the bug is described as a bug report, which is submitted to a bug repository. Finally the bug trigger checks the bug report and typically assigns a developer to fix the bug. The assignment process is time-consuming and error-prone. Furthermore, a large number of bug reports are tossed (reassigned) to other developers, which increases bug-fix time. In order to quickly identify the fixer to bug reports we present an approach based on the bug tossing history and textual similarities between bug reports. This proposed approach is evaluated on Eclipse and Mozilla. The results show that our approach can significantly improve the efficiency of bug assignment: the bug fixer is often identified with fewer tossing events.

The project entitled Audio Steganography is the application developed to embed an audio file in another audio signal. It is concerned with embedding information in an innocuous cover Speech in a secure and robust manner. This system makes the Files more secure by using the concepts Steganography and Cryptography. Steganography, poor cousin of Cryptography is the art of hiding messages inside other messages such that the very existence of the message is unknown to third party. The goal of cryptography is to make data unreadable by a third party, the goal of stenography is to hide the data from a third party Through the use of advanced computer software, authors of images and software can place a hidden trademark in their product, allowing them to keep a check on piracy. This is commonly known as watermarking. Hiding serial numbers or a set of characters that distinguishes an object from a similar object is known as finger printing. Together, these two are intended to fight piracy. The latter is used to detect copyright violators and the former is used to prosecute them. But these are only examples of the much wider field of stenography.The cover data should not be significantly degraded by the embedded data, and the embedded data should be as imperceptible as possible. The embedded data should be as immune as possible to modifications from intelligent attacks or anticipated manipulations .Thus it is necessary that the hidden message should be encrypted.

Now a day, all people are very familiar with mobiles. To make them free from work tensions, they will keep their mobile in silent. When they keep their mobiles in silent they may miss some important calls. Which will make them regret in future? So, to avoid this situation we came up with MODE CONVERTOR. By using this, if a mobile is in silent and a same mobile number is calling continuously 5 times then at the 6-time call of the same mobile number will automatically convert into ring mode. By this a person will not lose their valuable information. Mobile learning management systems are very important for training purpose. But considering the present scenario, the learners are equipped with a number of mobile devices that run by different operating systems with diverse device features. Therefore, developing a mobile application for different platforms is a cumbersome task if appropriate tools and techniques are not practiced. There are three categories of mobile application namely native, web based and hybrid. For mobile learning system, hybrid is an appropriate choice. In order to avoid re-implementation of the same hybrid application for different platform separately, several tools are proposed for example: Phone Gap, Adobe Air, Sencha Touch and QT, each with their own strength. With proper use of the strength of individual framework or the combination of frameworks, more compatible and more stable, cross-platform mobile learning application specifically for quizzes and assignments can be developed

The major aim of Location Based Services (LSB) is based on the location, it is used to provide services like food ordering system, Google map and some kind of e-shopping websites are completely based on locations. Based on the user location LSB provide continuous report to the un trusted server to obtain the services which can avoid privacy risks.LBS have existing privacy-preserving techniques as requiring a fully-trusted third party, it offers limited privacy guarantees and incurring high communication overhead. In this paper, we propose a user-defined privacy grid system which is called as dynamic grid system (DGS). Privacy-preserving snapshot and continuous LBS have four effective requirements. . (1) A semi-trusted third party is responsible for matching operations correctly and it does not have any information about a user's location. (2) Secure snapshot and continuous location privacy is guaranteed to defined adversary models. (3) The communication cost for the user does not depend on the user's desired privacy level; it depends on the number of relevant points of interest in the domain of the user. (4) The system can be easily enlarged to support other spatial queries without changing the algorithms run by the semi-trusted third party and the database server. Experimental results show that the DGS is more efficient than the state-of-the-art privacy-preserving technique for continuous LBS.

People in the world connected together and share their opinions, massages, comments, through social networks like facebook, whatsapp, twitter, linked in, Youtube. Mostly these are microbloggings and comments that are from youtube videos which allows limited number of words to post and there is no limit in reading the posts. Social networks have millions of active users per day, to discuss and share their opinions on currents news and events that are happening. So this is the best platform to predict the opinions of the public in terms of sentiment analysis. This analysis can give positive and negative opinions of the public, the scaling of the positive (+1 to +5), negative (-1 to -5) and neutral (0) and also emotions. In this paper predicting the sentiment analysis on youtube comments are by using some machine learning techniques and methods in R language. This sentiment analysis can give the decision making for the current events, markets, government policies and products.

 Abstract

Organizations share their data about customers for exploring potential business avenues. The sharing of data has posed several threats leading to individual identification. Owing to this, privacy preserving data publication has become an important research problem. The main goals of this problem are to preserve privacy of individuals while revealing useful information. An organization may implement and follow its privacy policy. But when two companies share information about a common set of individuals, and if their privacy policies differ, it is likely that there is privacy breach unless there is a common policy. One such solution was proposed for such a scenario, based on k-anonymity and cut-tree method for 2-party data. This paper suggests a simple solution for integrating n-party data using dynamic programming on subsets. The solution is based on thresholds for privacy and in formativeness based on k-anonymity

 Abstract

Magnesium (Mg) and its alloy are potential material for biodegradable implants which makes promising due its mechanical properties. However, corrosion of these metals alloys is too quickly results in losing mechanical integrity. The problem had risen in scientific committee to solve/reduce the corrosion rate and enhance the biocompatibility of the Mg-alloy. In order to reduce the corrosion, surface was modified with the hydroxyapatite (HAp) coating. The synthesis of HAp on Mg-alloy substrate was carried out by an electrodeposition method i.e., chemical deposition. The post treatment of deposited HAp on Mg-alloy with alkali solution which results in electrodeposited calcium hydrogenphosphate coatings into the bone-like hydroxyapatite coatings. Cyclic voltammetry and electrochemical impedance spectroscopy was studied to determine the barrier properties of the HAp coatings. Polarization test in a Hanks' solution was investigated to sense the protectiveness of the coatings, which is critical for better in-service mechanical integrity. The existence of the HAp coating and its morphology on Mg-alloy was verified using Fourier transform infrared spectroscopy (FTIR)

Three-dimensional ultrasound is an emerging technology in assessment to the complex cardiac anatomy and function. It promises 3-D image acquisition with the potential of more objective and complete functional analysis. In 3D echocardiography the anatomic information is missing and has limited field of view, the approach of this paper is to present multi-view fusion of 3D echocardiography where multiple images are achieve from different probe positions with an reduction of speckle noise using filtering techniques in order to improve the field of view. The multiple images are aligned and fused together for preserving a structure in a single multi-view fused image by improving field of view, this paper demonstrate the electromagnetic tracking system with an integration of sensors to the transducer which can be use for the fusion of multiple echocardiography images with an reduction of speckle noise by using filtering techniques.

 Abstract

Graphs are very powerful tools for describing many problems and structures in image processing. But graphs only describe some binary relations and are not always sufficient for modeling some complex problems or data. In order to overcome these difficulties and to provide a more viable tool for processing images by taking into account the topological and geometrical aspects of an image, combinatorial or hypergraph model is proposed. A relatively new class of algorithm termed combinatorial algorithm relies on approach to image processing. Combinatorics refers to arranging the elements into sub sets. This project aims three applications in particular to Denoising of Image, Image compression and Image Edge detection using combinatorial analysis. First the image can be converted into Hypergraph model by using Image Adaptive Neighborhood Hypergraph (IANH) model then this model can be used for different applications of image processing. Impulse noise is detected by analysing unit cardinality pixels in IANH model, that can be removed by different traditional methods and comparing PSNR and BER of these methods. In this project relates to a new method for lossless image compression, based on combinatorial (Hypergraph) analysis HGLC (Hyper Graph Lossless Compression). First the image can be represented into Hypergraph model by using IANH model. Then it can be modeled into number of rectangles to remove redundant data using algorithm to compress the image.

In remote correspondence, idea of parallel transmission of images is connected to accomplish high throughput and better transmission quality. Orthogonal Recurrence Division Multiplexing (OFDM) is one of the methods for parallel transmission. The possibility of OFDM is to part the aggregate transmission transfer speed into various orthogonal subcarriers all together to transmit the images utilizing these subcarriers in parallel. In this paper, proposed OFDM framework configuration is reproduced utilizing MATLAB simulink tool stash. The computerized adjustment plans for example, M-PSK (M-array Stage Move Keying) and M-QAM (M-array Quadrature Plentifulness Adjustment), which give method for parallel transmission, are contrasted with investigate the BER execution of outlined OFDM framework. Specified plans utilized as a part of OFDM framework can be chosen on the premise of the necessity of energy or range effectiveness and BER examination

In this paper, we analyze existing phase frequency detectors from aspects of theoretical analysis and circuit operation. Based on the circuit architecture, both classifications and comparisons are made. Then we propose a phase frequency detector for PLL design. The proposed phase frequency detector is simple in its structure and has no glitch output as well as better phase characteristics. Several prior art phase frequency detectors with the proposed one are compared for phase sensitivity, dead zone characteristics and maximum operation frequency. The proposed phase frequency detector shows satisfactory circuit performance with higher operation frequency, lower phase jitter and smaller circuit complexity. The speed of the proposed phase frequency detector is up to 3.5GHz. Moreover, the circuit design of a GHz PLL has been completed including high speed VCO, charge pump and phase frequency detector with an external loop filter.

Here a framework has been proposed that peruses the content experienced in regular scenes with the mean to give help to the visually impaired people. This paper portrays the framework plan and assesses a few character extraction techniques. Programmed content acknowledgment from normal pictures gets a developing consideration due to potential applications in picture recovery, mechanical autonomy and clever transport framework. Camera-based archive examination turns into a genuine plausibility with the expanding determination and accessibility of advanced cameras. Notwithstanding, on account of a visually impaired individual, finding the content is the primary imperative issue that must be tended to, in light of the fact that it can't be expected that the obtained picture contains just characters. At to start with, our framework tries to discover in the picture regions with little characters. At that point it zooms into the discovered regions to retake higher determination pictures vital for character acknowledgment. In the present paper, It has been proposed four character-extraction techniques in light of associated segments. The execution of the diverse techniques relies upon character measure. In the information, greater characters are more common and the best extraction technique turns out to be the succession: Sobel edge discovery, Otsu binarization, connected component extraction and rule-based connected component filtering.

MRI images form an essential part in the diagnosis and treatment process in medical field. Due to the magnetic field, which is the core operation procedure of MRI, there is a commotion in the acquisition and processing of the image in the form of noise. The diagnosis of the disease cannot be properly done owing to the noise present in the image which will hinder its path of accuracy. In this paper, we present an edge detection method using morphological gradient and type 1 fuzzy systems. These are found to be effective both on noisy and noiseless images and perform better than the conventional edge techniques like sobel, prewitt etc. The analyzing process is done using PFOM and PSNR parameters.

Abstract: The reduction of IC Engine fuel consumption by improved combustion using the modified new designs to increase its performance and optimize the existing designs is implemented. Air flow in CI Engine has effects in the atomization and dispersion of fuel flown into the manifold. The improved atomization of fuel injected allows for progressive and complete burning which helps in reducing the Knock. A four stroke CI Engine with 8 Horse Power is chosen for the current work to explore the performance characteristics. The swirl flow movement of the air is a major parameter in the optimization of the engine performance. In order to improve the air flow in the inlet manifold use of Convergent- Divergent Nozzle to Increase the velocity and turbulence at the end of the manifold. Finally nozzle provides better combustion of the injected fuel. The performance parameters were observed and compared with normal nozzle. It is noticed that at all loads mechanical efficiency gradually increases BSFC reduces. At higher load break power and indicated power also improves. Hence it is concluded that by using Convergent Divergent nozzle gives better results compared with normal manifold

 Abstract

This paper deals with a natural draft wet-cooling tower with various inlet conditions. A commercial code FLUENT has been used to simulate the transport phenomena inside the tower. In this a 50 tons cooling capacity model has been taken as reference model. The developed model is analyzed with two air flow rates in vertical direction and by combining air inlet temperature and water inlet temperature. The developed model has been updated and the height of the water inlet is increased from the basin height and the same analysis is done by using the two flowrates of air and water into the system. It is observed that the temperature and humidity inside the tower are the main influence factors on the performance of cooling tower. It is also observed that due to increase in height to an optimum condition the performance of the cooling tower is increased and further increase in the height decreased its performance. Analysis shown that due to temperature of fluid inlet, cooling capacity of the tower has been improved with increase in air airflow rate when compared with natural aspirated air. A turbulence model of k-? with energy equation is used for simulation

 Abstract

In this project, we are using the concept of "Zeer Pot Refrigeration" Technique for Air cooling. Air cooling is a method of dissipating heat from the system. It works by making the air to flow over the surface area of the cooled object. This cooling effect can be increased by having an increased flow of air over its surface. In all the cases air has to be flown over the object or surface from which is cooler than the air flown. The air has been cooled by chilled water and the heat transferred to that medium is transported outside where, often, fan driven water-to-air heat exchanging is again affected to reject the heat into atmosphere. Ambient temperature simply means ?The temperature of surrounding" and will be same as room temperature indoors. Refrigeration is the process of removal of heat from space where it is unwanted and transferring the same to the surrounding environment where it makes little or no difference. Zeer Pot is an evaporating cooling refrigeration device which does not use temperature. The rate of cooling depends upon outside temperature and relative humidity. In this project, we are combining the concept of Zeer Pot refrigeration and the air cooler. By using secondary liquid in the Zeer Pot and circulating in a copper pipe over the fan by which it absorbs heat from the closed system. Cooling depends upon the difference in the ambient temperature and the secondary liquid temperature. Then the Zeer pot full of water is used to cool the water flowing through it back to fan and it blow cool air. Various parameters that affect the cooling rate are ambient.

 Abstract

Four stroke Diesel cycle and Otto cycle engines have very low thermal efficiency due to high amount of energy is lost in exhaust. It is estimated about 28%of fuel energy is lost in exhaust of engine and 22%of cooling lost .Remaining percent of energy of the fuel about 50 % of energy gets converted in to work. The development of new engine is proposed to use the energy of exhaust and also cooling of the engine in two more strokes of IC engine leading to a external engine. The internal combustion engines are generally a major source of air pollution. However the spark ignition engines are recognized by their carbon monoxide and unburned hydrocarbon emission. One of the methods used to reduce the emission of these pollutants is the use of external combustion engine. This paper describes the development of an external combustion engine which uses air in tanks at pressures of 30 - 50 ?P? and at ambient temperature as combustion energy carrier, and hydrogen, alcohols or traditional motor fuel from organic minerals as chemical energy carrier. Research workings out are in the field finished to level of practical use. The mathematical and simulation model has been developed, tested, and verified to simulate a 4-stroke cycle of a spark ignition engine fuelled with gasoline

An attempt is made to obtain the minimum temperature and pressure and to study the variation of velocity and entropy. In our present research a model of high speed rotating turbine is created with blade angle 150 and later which is simulated for results by using two different fluids i.e., oxygen and nitrogen. Here, creo element/pro-E is used to create the model of turbine using available data of hub, shroud and blade profile. ANSYS FLUENT 14.5 is used to mesh the model, to specify the simulation settings and physical parameters required to describe the flow through turbo expander at inlet and to examining and analyzing the output results. Using these results we can determine that how the variation will occur by using various fluids. Various graphs are plotted indicating the variation of velocity, entropy and mass flow rate to analyze the flow through Expansion turbine.

 Abstract

SOLEKSHAW indicates the meaning as SOLAR-ELECTRIC-AUTO RICKSHAW. In the busy streets of cities, mainly in Asian subcontinent, we find many tricycles and auto rickshaws. Auto rickshaws are driven by fossil fuel, which produces too much environment pollution. On the other hand tricycles or cycle rickshaws are used to carry two no of passengers and suitable for narrow streets at a speed below 20 Km/hr. Since it is not using any kind of fossil fuel, it is free from environmental pollution. But it is driven fully by manual power, which is a very strenuous job for driver. Now-a-days considering the climatic changes caused by environmental pollution, introduction of green vehicles has become very important. Especially in busy streets of cities, pollution is at alarmingly high levels due to very slow movement of automotive vehicles. Keeping this in mind, introduction of Solar Powered Motor assisted pedicab has been thought to be a wise prerogative, mainly in the busy and narrow streets of cities.

In this paper, an attempt is made to deposit microcrystalline diamond films by Hot Filament Chemical Vapour Deposition (HFCVD) method on Co-cemented tungsten carbide cutting inserts. To restrict the catalytic effect of cobalt binder phase for the formation of non-diamond carbon phases such as graphite and improve the adhesion between diamond and WC, inserts were pretreated with combined HCL and HNO3 solution. Seeding of the substrates was followed separately with Ti, Mo, W and diamond powders. Depositions were done at a pressure of 2.666 kPa, substrate temperature of 7000C, and filament temperature of 21000C with constant CH4 / H2 flow ratio of 0.5 / 100 SCCM. Characterization and purity (sp3 / sp2) of the acquired coatings have been evaluated by Scanning Electron Microscope (SEM) and Raman Spectroscopy. It is observed that there was no improvement in coating morphology when the treated samples were seeded with Ti, Mo or W powders. These results suggested that a continuous diamond film with well facet morphology is deposited with acid treated sample surface seeded with diamond powder. During dry machining, compare to uncoated tool, HFCVD diamond coated tool exhibits remarkable inertness towards aluminium leading to substantial reduction of cutting force and improved work-piece surface finish.

 Abstract

Indeed, it is undoubtedly accepted that the presence of SPV (solar photovoltaic) module is ubiquitous. The power voltage characteristic of photovoltaic (PV) module operating under partial shading conditions, under different tilt angles the output power obtained will be varied. In this paper a new method of obtaining maximum power by using bypass diode is implemented on a PVTR (photo voltaic trainer research system), such that uninterrupted output power can be achieved. The experimental results verify that the output power is varied with the varying of panel cells that are under shading area and with the change in the angle. Compared to many ways of studying the performance of a SPV module at different places, It is very convenient to study the effects that impact the electrical parameters which can be observed on a single equipment at one place named as standalone PVTR system
