Steam Jet Ejector Performance Using Experimental Tests and Computational Fluid Dynamics - A Review
-Arth R. Patel ; Mr. Jayesh Khunt
Jet ejectors are popular in the chemical process industries because of their simplicity and high reliability. They are widely used to generate vacuums with capacity ranges from very small to enormous. Due to their simplicity, constant-pressure jet ejectors that are properly designed for a given situation are very forgiving of errors in estimated quantities and of operational upsets. Additionally, they are easily changed to give the exact results required. The purpose of this project is to optimize the geometry of steam jet ejector used for refrigeration application in chemical plant. Exhaustive survey has been conducted on the influence of geometrical parameters on the efficiency of the ejector as well as critical flow parameters to improve the overall performance. The use of computational dynamics has been widely adopted by researchers to improve the performance of jet ejector. CFD provides detail insights on the flow characteristics, which allows accurately optimizing the ejector geometry. Since the ejector requires single point design for specific applications, using computer simulations early in the design process will significantly the requirement of prototyping trials. Utilizing the benefits the CFD offers, the dimensions of the ejector system has been measured, which will be further utilized to develop a computational domain and perform numerical iterations to obtain fluid flow characteristics. The results obtained through CFD analysis will be used to optimize the geometry of the ejector, to achieve better efficiency by reducing pressure drop across the ejector geometry Read More...

Role of Additives in Expansive Soil to Improve Stabilization Performance using Biomass Silica
-S. Manimaran ; Gayathiri .K; Sinduja .R; Vengadesh.S
Soil is the major base for any type of structure, it mainly consists of minerals, organic matter, liquids etc. It represents the stability of any type of soil which the structure retains itself without affecting its properties. Black cotton soil is one among the type of expansive soil. Its property is of swelling excessively when wet and shrinks highly when exposed to dry condition. In black soil it mainly consists of montmorillonite mineral which has the ability to undergo large swelling and shrinkage. To overcome this, properties of soil should be enhanced by artificial means known as ‘Soil Stabilization’. It is the procedure in which existing properties of soil are improved by means of addition of chemical or any admixture.The main additive used in this is Bagasse Ash which is a fibrous material obtained from sugarcane plant after the extraction of sugarcane juice. Sugarcane industry produces 30% bagasse for each lot of crushed sugarcane. It mainly consists of silica content. The tops and leafs of sugarcane stalks which is called as sugarcane straw which is also one of the additive which is used in it. Sugarcane straw ash (SCSA) which has high pozzolanic activity. In this laboratory experiments were conducted on this expansive soil with partial replacement by bagasse ash. This paper highlights significant increase in properties of this black cotton soil obtained at replacement of bagasse ash and SCSA which are free from chemical and it mainly protects the environment from any hazards.In this study laboratory experiments were conducted on black cotton soil with partial replacement by different percentages (3%, 6%, 9% and 12%) of Bagasse Ash and Sugarcane straw ash mix proportions. This paper highlights significant increase in properties of black cotton soil and analysis for the use of bagasse ash and sugarcane Straw ash waste in pavement construction will be made. Read More...

Voice Liveliness Identification Assisted by Noise Categorization
-Jayashree G Magadum ; Prof. Sandhya Bevoor
Voice Activity Detection (VAD) is a very important front end processing in all Speech and Audio processing applications. The performance of most if not all speech/audio processing methods is crucially dependent on the performance of Voice Activity Detection. Voice activity detection (VAD), is to detect the presence of speech in an audio signal degraded by noise, is widely applied in numerous modern speech communication systems. Since speech signals are non-stationary and contain many transient components, it is appropriate to use, perceptual wavelet packet transform (PWPT) as a tool for feature extraction especially in noisy environments. Voice activity detection (VAD) is a process, which can detect speech and non-speech segments from a audio signal. This method combines a noise robust speech processing feature extraction process together with SVM models trained in different background noises for speech/non-speech classification. A multiclass SVM is also used to classify background noises in order to select SVM model for VAD. Read More...

Algorithm to Manage Traffic Light Control to Prioritize Emergency Vehicles
-Maheshkumar V. Makwana ; Hitesh C. Patel
Rapid increase in number of vehicles on the roads as well as growing size of cities have led to a plethora of challenges for road traffic management authorities such as traffic congestion, accidents and air pollution. This work focuses on the particular problem of traffic management for emergency services, for which a delay of few minutes may cause human lives risks as well as financial losses. The goal is to reduce the latency of emergency services for vehicles with minimum unnecessary disruption to the regular traffic, and preventing potential misuses. In this work, we propose STLO (Short Time Less Obstacles) algorithm, which itself describes to bring the patient in a short time to hospital by avoiding unnecessary or necessary stops/halts. Proposed system specially designed for an emergency vehicle, thereby introducing Application Unit (AU), messages passing and also by assigning a specified region or boundary. Whenever an emergency vehicle enters into specified area, the Application Unit detects presence of emergency vehicle. Emergency vehicle passes Vehicle ID, its direction related to traffic signal, average speed, and destination location to AU. Then AU passes massage to the traffic signal controller. Traffic signal control is already equipped with historical data and road patterns to calculate shortest path. Traffic signal turns the traffic light to green so that emergency vehicle passes through the traffic signal intersection. Pre-emption is active until the emergency vehicle passes through the intersection. Read More...

Efficient Noise Removal Based on Non-Local Means Filter and Its Method Noise Wavelet Packet Thresholding
-R. Christal Jebi
Image denoising includes operation of the image data to yield a visually high quality image and a major process in image processing, pattern recognition, and computer vision fields. The chief aim of image denoising is to re-establish the original image from a noisy image and help the other system (or human) to understand it well. Even though introduces many methods there only reduced visual quality, causing blurring and artifacts in the image. In this project, uses a new technique called wavelet packet transform and adaptive wavelet thresholding to denoise the image and improve visual quality. wavelets based denoising method consist of three steps namely, first to compute the wavelet packet transform, the next step to Remove noise from wavelet coefficients using wavelet packet thresholding and the third step is to reconstruct the enhanced image using inverse wavelet packet transform. Unlike standard wavelet-based methods Wavelet packet transform (WPT) used for image decomposition. The proposed method namely, Fast OWB extraction is a new adaptive thresholding function introduced to improve the denoising efficiency. Hence chooses an adaptive threshold value which is level and subband dependent based on analyzing the sub band coefficients. Estimation of dominant coefficients based on Maximum a posteriori (MAP) estimate to enhance or eliminate the wavelet coefficients. The resultant method yields better peak signal noise ratio with visual image quality measured by universal image quality index compared to standard denoising methods. Read More...

-Nutan Kumari
Friction damper is used for the dissipation of an earthquake energy which may cause damage to the structure. It is a well-known energy dissipation devices. The purpose of this study is to analyze a single-degree-of –freedom (SDOF) building structure. Friction damper is used to connect parallel structure with each other. Friction damper is installed between two parallel structures to reduce inter-story displacements of structures subjected to the external loading. Numerical model (Viscoplasticity model) is used to model the friction forces in the proposed damper. The equation of motion is solved by the Newmark’s step by step method and seismic response of structure is worked out under earthquake excitation. Friction damper is used to reduce the structural seismic found response. The mutual pounding of structure is also reduced by structure with a friction damper. It is that during major earthquake, the friction damper slip at a predetermined connecting load before yielding occurs in member of a frame structure and dissipates a large proportion of seismic energy during earthquake. In this paper investigation is carried out to study the structural response of a parallel structure connected by a friction damper using. The specific objective of this study is to evaluate the importance of a friction damper in reducing the seismic response of parallel structures which are connected by friction damper with each other.

An Algorithm used For the Enhancement in Detection and Determination of Duplicated Regions in Copy-Move Image Forgery
-Namrata Awasthi ; Harimohan Pandey
In this paper we have studied the various techniques used to improve the key point localization and detection of duplicated regions in same image. These techniques create an enduring image by copying the certain potion of an image and pasting it to the different location of the same image. The key points in this image cloning are that the content is copied from the same image so the noise components, texture and patterns are compatible with the same image. The most important thing is the discovery of similar parts in the same image and then it becomes more complex to make clusters of those parts. We have presented Scale Invariant Feature Transform (SIFT) technique to determine the feature matches in the image. Read More...

-Pankaj Rakte ; Mohit Rathod; Vishal Raskar; Sanket Devatwal; Prof. (Dr.) Mrs. N.R. Kulkarni
World’s 90-95% industry works on power. Power is very important part of today’s industrial and commercial revolution. It is generated conventionally as well as some natural resources are used in order to fulfill today’s power wants. The hydro power stations are the main resources of the electricity and power. Wind power station and solar power generation are some of the another source. Bio gas power station may also be there. Still as for as the usage increases, the generation cannot be increased in that proportion. Hence there is always shortage of electricity. Hence we have to planningin order to minimize the shortages. We can build the small solar power plant. This will help to minimize the dependency of the conventional power plant. Day by day the difference between the electricity consumption and demand is increases due to this, shortage of electricity is increase gradually. To minimize these shortages we want to use the non-conventional energy sources. The solar power generation is the best way to minimize this difference between demand and consumption. Read More...

A Study of Fog Removal with Its Types and Techniques
-Narendra Singh Sikarwar ; Deepak Motwani
Fog reduces the visibility of a scene and thus the quality of several computer vision methods which use feature data. This is the function of the depth for the creation of fog. The calculation of depth data is under constraint issues if single image is obtainable. From this time, fog removal from image need expectations or preceding data. Fog removal techniques compute the depth data with several expectations, which are discussed in facts here. This structure is relayed on two clues: calculation of the perceptibility distance, which is computed from the camera forecast equations and the blurring due to the fog. Since, the water particles moving in the air, sky light gets dispersed and, emphasis on the origin zone, which is one of the shadiest zones of the image. Fog, haze and smoke are a big cause of road misfortunes. In the process of fog removal, it decreases the contrast level of the image that disturbs the visual value of the image. On the ground of computer vision, visual value and visibility level of an image is unnatural by air light and attenuation occurrences. Air elements, which present in the air and disturb the visibility level of anything, are known as noise between witness and object. Read More...

-Shraddha Sadashiv Dhumal ; Jalaja Gundi; Poonam Khirid; Manashri Yadav
In recent years, PQ (power quality) problem makes quality of power supply drop, which even triggers power accident, so PQ has attracted widespread attention. In this paper we deal with the power quality problem- harmonics. Two different combinations of the load are taken with linear and non-linear. A MATLAB program is designed to calculate total harmonic distortion of the system using FFT(fast fourier transform). In the paper, the disturbances specially harmonics present in the power systems are detected with equipment like `power analyzer` or ‘digital signal oscilloscope’ The values of the power signal obtained from above method are then inserted into the Simulink or MATLAB program and the signal is analysed on parameters and these results are finally cross-verified with the result obtained from above devices. The simulation results and the theoretical analysis show that the model in this paper could simulate the harmonic disturbance well, which can provide data and basis for detection and identification of PQ and further control measures.

A Review Study on Exhaust Gas Recirculation (EGR) Cooler Design and using CFD to Enhance Its Performance
-Ibrahim Hussain Shah ; Bhupendra Singh
Strict emission standards are now in place that set specific limits to the amount that can be released into the environment. Reduction of exhaust emission of a vehicle is done through an EGR technique. EGR coolers are subjected to severe fouling such that their thermal efficiency can drop as much as 30 percent within a very short period of time. Durability of EGR cooler performance is key issue that affects the function of EGR system as anti-pollutant device. Decrease of thermal efficiency and increase of gas pressure drop caused by soot deposition implies higher EGR gas temperature and lower EGR flow. Selection of heat exchanger technology and definition of design parameters have an important effect on this degradation. This paper reviews a compendium of different tests, where different technologies and sizes of EGR cooler have been exposed to different engine test cycles. The focus is going to be mainly on Computation fluid dynamics (CFD) and to increase effectiveness of EGR cooler used in EGR system. Read More...

A Novel Approach for Data Cleaning using CFDs Algorithms
-Gangamma ; Thara D K; Girish L
The main objective of this paper is to give idea of conditional functional dependencies. As usage of computers is increasing are day to day, the storage of data also is more. The data has to be removed and cleaned if it is not helpful. Data cleaning should be done repeatedly by finding out the faults. Hence this gave rise to conditional functional dependencies. CFD (Conditional functional dependency) is an integrity constraint. Conditional Functional Dependencies were used to eliminate redundancy. Traditional FDs (functional dependencies) were recently replaced by CFDs for data cleaning. Functional Dependencies were mainly used for schema design whereas CFDs were aimed at capturing the constancy of data by using patterns of semantically or meaningful related constants. Inconsistent Relational data can be identified by using Conditional Functional dependencies. The detection problem is more complicated in the case of CFDs when compared to Functional dependencies also removal patterns in Conditional Functional dependencies will establish more challenges. For discovering CFD two methods are used. First, CFD Miner is used to discover CFDs which have constant patterns. These constant CFDs are important for discovering an object to clean .The second algorithms which were used for determining general CFDs is CTANE, CTANE is considered as expansion of TANE which is used in removal of Functional Dependencies. These algorithms used for cleaning are based on type of application by the user. Read More...

Security Enhancement over AODV by Establishing Symmetric Key Cryptography
-Amruta Upadhyay ; Vanaraj.B.Vaghela
Communication takes place by routing protocols in efficient and effective manner in wireless network. Efficient protocols are used to forward data packets without much packet loss. MANET (Mobile Ad hoc Network) because of maliciousness that intentionally disrupts the network by using variety of attacks and due to routing protocols e.g. AODV (Adhoc On demand Distance Vector), which were already developed without considering proper security features to prevent the various kinds of attacks. MANETs are frequently established in insecure environments like disaster sites and military applications. The AODV routing protocol was initially developed without considering security in mind. But there are many security schemes available that make AODV secure. However, by doing more research in this area, one major flaw in any of the existing secure routing protocols was discovered. That is security schemes that are available consume more processing power and required complex key-management system. In this work we are going to present a novel security scheme which integrates Key Distribution & Authentication Server and Secure Hash Function mechanism to protect the AODV routing protocol that is capable of defending itself against both malicious and unauthenticated nodes. The proposed security scheme will be simulated in the Network Simulator 2. Read More...

-Chaudhari Darshana D. ; Vanaraj B. Vaghela
A Mobile Ad hoc Network (MANET) is an accumulation of portable hubs depending neither on settled correspondence constructs nor in light of any base stations to give network. Accordingly, the steering conventions for a MANET must be versatile and equipped for keeping up courses as the qualities of the system integration change. Outlining a proficient and dependable directing convention for such systems is a testing issue. The AOMDV (Ad hoc on interest Multipath Distance Vector) is an on interest directing convention taking into account separation vector idea and uses jump by-bounce steering way to deal with do transmission. In this exposition work, we propose a plan which could consider energy conservation and briefest way. In this steering plan, we have consider both the most limited way and the vitality preservation in multipath route with proposed vitality based multipath directing. The whole recreations are performed in Network Simulator 2. Read More...

A Grid Connected Flicker Compensation of DFIG for Power Quality Improvement by using Ann
-P.V.Vijaykumar ; R.Sakthivel
For the rotor side converter (RSC) of doubly fed induction generators (DFIGs) a novel terminology called combined vector and direct power control (CVDPC) is considered. The control system is resultant of a direct current control through proper voltage vectors selection from a switching table. In reality, the proposed CVDPC has the advantage of vector control (VC) and direct power control (DPC) in a compressed control system. Its advantage in contrast with VC consists of quick dynamic outcomes, toughness besides the machine factors modification, reduced computation and minimal realization. Alternatively it includes serves in relation to DPC, with fewer harmonic alteration as well as decreased power fluctuation. A vast simulation analysis by means of MATLAB/Simulink is performed on a 9-MW wind plant made of six 1.5 MW DFIG basis wind turbines. The operation of the proposed CVDPC technique is compared through both VC and DPC during steady-state and transient state. Simulation outcomes verify the dominance of the CVDPC over both VC and DPC.

other information. Many different carrier file formats can be used, but digital images are the most popular because of their frequency on the Internet. For hiding secret information in images, there exists a large variety of steganographic techniques some are more complex than others and all of them have respective strong and weak points. Different applications have different requirements of the steganography technique used. For example, some applications may require absolute invisibility of the secret information, while others require a larger secret message to be hidden. This paper intends to give an overview of image steganography, its uses and techniques. It also attempts to identify the requirements of a good steganographic algorithm and briefly reflects on which steganographic techniques are more suitable for which applications.

A Survey Paper on Image Adaptive Watermarking Techniques
-Jatin Prajapati ; Hardik Kadia
A digital image watermark is a signal permanently embedded into a digital image that can be detected or extracted later by means of some operations for authentication purposes. This paper discusses the results of evaluating three conventional image watermarking algorithms for performance and robustness. The findings are based on experiments on a standard LENA image and thus a comparative analysis between the algorithms becomes apparent and very clear. Three algorithms namely LSB (Least Significant Bit), DCT (Discrete Cosine Transform) and DWT (Discrete Wavelet Transform) were implemented in MATLAB and various results were collected with respect to performance and robustness. LSB embedded watermarks were easily removed using techniques that do not visually degrade the image to the point of being noticeable. Cosine transform algorithm was good in both performance and robustness. The wavelet domain proved to be highly resistant to both compression and noise, with minimal amounts of visual degradation but the original image was significantly affected by the embedding. The numeric data included in the paper make this comparison more formal. Read More...

Design and Evaluation of an Efficient Congestion Adaptive Routing Protocol in MANET
-Bhavana B K ; Shashidhara M S
Routing protocols for mobile ad hoc networks (MANETs) have been explored extensively in last few years. Routing may let a congestion happen which is detected by congestion control, but dealing with congestion in reactive manner results in longer delay, and unnecessary packet loss and requires significant overhead if a new route is needed. Adaptation to the congestion helps to increase both the effectiveness and efficiency of routing. These problems are solved by the congestion-aware routing protocols in certain degree. These protocols which are adaptive to congestion status of mobile ad-hoc network can greatly improve the network performance.This project work gives a proposal for a new algorithm, Efficient Congestion Adaptive Routing Protocol (ECARP) using cross layer design, which out-performs even during constrained situation. The project is simulated using the popular network simulator NS2 and the results are compared with the Ad hoc On-demand Distance Vector (AODV) routing protocol which is one of the dominate protocol design for MANET. Through simulation in NS- 2 that ECARP out-performs over AODV routing protocol in normal situation. Read More...

Crank Operated Maize Sheller
-Girish Karikatti ; Roopa Lokeshwar; Sameer Sattur; Jangali Satish G; Anjali Kathani
As all of us are aware, maize is one of the most important constituents of our food. But do we all know, how laborious it is to shell the maize? Dehusking and shelling are important post-harvest activities in maize crop, predominantly done by women. These activities involve a lot of drudgery as these are done manually. The maize shelling with the tool makes women's lives difficult and yields very low level of output. Moreover, dehusking as a separate activity precedes shelling that brings additional burden on farmers. They may employ labourers or use machines. But in villages, there is a shortage of labourers, and their wages are also pretty high. The farmers or field owners find it difficult to afford the machines. In order to make it affordable and more convenient to shell the maize, and as a part of our academic project, we have developed a “Crank Operated Maize Sheller†using ergonomic and mechanical considerations for dehusking and shelling. It consists of feeder from where the maize is inserted. The crank is connected to the blade. When the crank is turned, the blade rotates and shells the maize. The machine is operated by 1 person and requires feeding of cobs one by one. Read More...

Study of the Effect of Cyclic Loads on the Joint in a Vertical Tail of Aircraft Structure
-Hemanth Kumar ; Dr. B. Ravindra
Joints are obvious critical locations in the aircraft structure because of the stress concentration. Joints are very common in every structural component of aircraft. Vertical tail (VT) is one of the major components of the airframe. Rudder attached to the VT is the control surface, which is used for controlling yawing motion of the aircraft. Side load on the VT causes it to bend on either side with respect to fuselage axis. Deflection of rudder introduces side load on the VT. This project includes the study of the effect of cyclic loads for crack initiation at the critical location of the VT. Stress analysis is the approach followed to identify the critical location. Finite element method will be used for stress analysis of the component. Loads representative of a small transport aircraft will be considered in this study. VT bending will cause tension and compressive stress field in the skin on either sides of VT. Joint details will be simulated through a local refined analysis to capture the gradient stress field near the concentration zone. Structure undergoes fatigue due to fluctuating side loads on VT. Fatigue damage is estimated using linear damage theory. S-N data curve of the aluminium alloy material used for the VT skin will be considered for stress based damage calculation. Read More...

-Rajasuguna ; B.Asfiya
With the advancements in the variable speed system design and control of wind energy systems, the efficiency and energy capture of these systems is also increasing. Intelligent control techniques can play a vital role in improving the performance and the efficiency of Wind Energy Conversion Systems (WECS). This paper proposes the Pitch control of a Doubly Fed Induction Generator based wind energy system with the aim of maximizing the power output by using ANN controller along with Hill Climbing Search (HCS) algorithm.Pitch control is the most common means for regulating the aerodynamic torque of the wind turbine and this algorithm searches for the peak power by varying the speed in the desired direction. The generator is operated in the speed control mode with its reference speed being varied in accordance with the magnitude and direction of change of active power. The peak power points in the Power (P)-Speed (ω) curve correspond to dP/dω=0. This fact is made use of in the optimum point search algorithm. The proposed method is computationally efficient and can be easily implemented in real-time. This system is modeled using MATLAB/Simulink. Simulation results prove the efficiency of this technique.

Implementing Dejong Function by Random Initialization
-Noopur Tyagi ; Rakesh Kumar
Genetic Algorithm (GAs) are search procedures based on principles derived from the dynamics of natural population genetics. Performance of genetic algorithms mainly depends on type of genetic operators – Initialisation, Selection, Crossover, Mutation and Replacement used in it. Success of Genetic Algorithm mainly depends upon the individuals selected in the initial population and the size of population. If the individuals chosen in the initial population are poor, it will result in weaker solutions and premature convergence towards optima. There are different methods to initialize Genetic algorithms but most of the time random initialization is used. In this paper minimum value of dejong’s function is observed at different generations.

Domain Specific Code Repository using Elasticsearch
-Pravin Mishra ; Mrs. Chetna Achar
Various software development companies have their own code repository for future reference. This code repository consist of previous projects and code worked on, by company employees. Taking up a new project or working on a module of some current project, developers come across coding challenges which may have been faced by some other employees previously in the same project or some other project. These employees may not be the part of current project or may have already left the company. But the probability that they found out a solution for the problem is absolute. The solution to this problem exists in the code repository in form of chunks of code in files. However searching for a specific peace of code in the repository may be a tedious job. And sometimes may even take more time than writing the code itself, from scratch. This paper proposes the use of elastic search for indexing the code repository to enormously accelerate the search proses. Read More...

Sheltered Information Distribution Publish with Detachment Base Pulling Out
-Naveen Kumar. P ; M. K. Raahul Kumar
The algorithms also preserve important properties of the dataset, which are important for mining operations, and so guarantee both right protection and utility preservation. Watermarking may distort the original distance graph. The Proposed watermarking methodology preserves important distance relationships, such as: the Nearest Neighbors (NN) of each object and the Minimum Spanning Tree (MST) of the original dataset to unreadable file. The System proves fundamental lower and upper bounds on the distance between objects post-watermarking file. In particular, establish are striated isometry property, i.e., tight bounds on the contraction/expansion of the original distances. This analysis is used to design fast algorithms for NN-preserving and MST-preserving watermarking that drastically prunes the vast search space. Read More...
