EXUDATE DETECTION FROM RETINAL IMAGES USING IMAGE PROCESING TECHNIQUES
-R. Indu priya ; Dr.S.N.Gethalakshmi
One of the popular research areas in image processing is analysis of medical images. Digital images are analyzed to diagnose different medical imaging problems. Diabetic retinopathy is the most common form of diabetic eye disease, which occurs when the level of insulin increases in blood so the damage takes place on retina, which may further lead to blindness. The research is carried out in the in the following manner. In first phase, preprocessing method is developed to segment the retinal images. This method uses the mean and variance based segmentation and ratio of hue and intensity channel is used to remove the noise in retinal images. In second phase, post-processing technique is created to detect the optic disc and exudate in the retinal images. This method uses the Hough transform technique to detect optic disc. Morphological closing is to extract the blood vessels, and applying adaptive contrast enhancement technique to the extracted blood vessels in order to improve the contrast of exudate. OTSU algorithm is used to calculate threshold value to detect exudates. The proposed work applies a Hidden Markov Model (HMM) method for classification of exudate and non exudate region. The proposed system is tested and evaluated on publicly available HOOVER, STARE retinal image database using performance metric such as sensitivity, specificity and accuracy. Through adoption of HMM classifier accuracy was 97.5% within a period of 0.9 seconds. Read More...

SEARCHING WEB THROUGH QUERY ROUTING PLANS
-A.Sudheerika ; Dr. C.Kiranmai
In future web will not be a collection of documents but can become sets of linked data sources. Keyword search is a way to search this kind of web as in present scenario, but will impose a high cost. This is because keyword search has to be applied to every source to find a match for any of keywords of the query. Hence routing keywords only to relevant sources that can reduce the unnecessary cost of running keyword search queries over all sources is needed. Also in the linked web setting a query is better answered with the help of data present across multiple sources i.e. the result of search is relevant combination of sources rather than relevant source. This can be achieved through a novel method which we propose in this paper. This method involves generation of top-k routing plans which can direct the search to appropriate sources based on the presence of keywords .A graph representing relationships between keywords and the data elements related to them at different levels i.e. at level of keywords, data elements, element sets, and sub graphs that connect these elements is generated. This is called multi-level keyword-element relationship (KER) graph. A scoring mechanism is proposed for computing the relevance of routing plans by ranking elements as well as relationships thus providing best results to the query. Read More...

Using Ontology for Search Results Annotation from Web Databases
-M.Sangeetha ; P.Karthikeyan
Annotating search results from many search engines is a big challenge, data encoded in the returned result pages come from the underlying structured databases. Such type of search engines is often referred as Web databases (WDB) search result records (SRRs). Having semantic labels for data units is not only important for the above record linkage task, but also for storing collected SRRs into a database table. Early applications require tremendous human efforts to annotate data units manually, and aligning the data unit as well as text nodes becomes difficult to overcome these proposed consider data alignment problem by using ontology based system .Ontology based system performs after the feature are derived from the text unit nodes and data unit nodes in the feature extraction after that perform the results then we align the data based an ontology. In this research the each self interest server is responsible for computing mappings concerning a specific ontology element, using a specific alignment method. Each self interest server interacts with other self interest server with whom it shares the same data unit concerning the validity of the mappings it computes. Interacting self interest server form a graph, with composed of text nodes and data unit nodes in the search results records (SRR), text nodes representing alignment decisions and utilities, respectively. Self interest server need to reach an agreement to the mapping of the ontology elements consistently to the semantics of specifications with respect to their mapping preferences. Read More...

-Dipti Rani ; Rajneesh Chaudhary; Dr. S. K. Garg ; Vikas Goyat
Job shop scheduling is an important step in planning and manufacturing control, and at the same time remain one of the well-known optimization problem. In a job shop scheduling problem, a set of jobs has to be processed on a set of machines such that a specific optimization criterion is satisfied. As job shop scheduling highly affects the efficiency of manufacture, a large number of optimization techniques have been applied to the problem to achieve a satisfied solution over the years. Here, an effort has been made to optimize a real world scheduling problem using a well-known technique genetic algorithm. Genetic algorithms (GAs) are a very popular heuristic which have been successfully applied to many optimization problems within the last 30 years. GAs are stochastic global search methods that mimic the natural biological evolution [1]. GAs operates on a population of possible solutions applying the principle of survival of the fittest to produce better and better approximations to a solution. In this work few conventional job shop scheduling problems are first solved using Genetic Algorithm and results are compared for validation. Then GA is applied to real world job shop scheduling problem. Few assumptions are made to the real world industry data to reduce the constraints. A model of the problem is developed in MATLAB platform and results are plotted, analyzed and discussed. Read More...

Experimental Investigation Of The Effect Of Exhaust Gas Recirculation On Performance, Emission And Combustion Charatersitcs Of A Single Cylinder Low Heat Rejection Diesel Engine Using Rice Bran Biodiesel
-Shiva kumar ; Prakash S Patil; Dr. Omprakash D Hebbal
All diesel engines are most trusted power source for automobile vehicles of all over the world. But, it emits more exhaust emissions like hydrocarbon (HC), carbon dioxide (CO2), carbon monoxide (CO) and oxides of nitrogen (NOx). The rapid depletion of conventional fossil fuels has promoted research towards alternative fuels for internal combustion(IC) engines. In this study rice bran biodiesel (RBBD) used as an alternate fuel as a substitute for diesel. From the experimental investigation, the diesel has lower brake thermal efficiency and higher brake specific fuel consumption. To overcome this, rice bran biodiesel without exhaust gas recirculation (EGR) is used in low heat rejection (LHR) engine. This results in the increase of brake thermal efficiency and correspondingly reduces the brake specific fuel consumption, but increases the NOx emissions. It is mainly due to the peak combustion temperature, oxygen concentration in the combustion chamber and the residence time of high temperature gas in the cylinder. To overcome this, EGR is being used to reduce and control the NOx emissions by lowering oxygen concentration in the combustion chamber. Hence by analysis, rice bran biodiesel blend with 5%, 10% and 15% EGR in LHR engine provides better performance, combustion and emission characteristics when compared with neat diesel without EGR in conventional engine and rice bran biodiesel without EGR in LHR engine.

-SURESH A ; PRAKASH S PATIL; OMPRAKASH D HEBBAL
The performance, emission and combustion characteristics of a single cylinder four stroke LHR engine when fuelled with Neem biodiesel and are investigated and compared with the results of standard diesel with Exhaust Gas Recirculation system. It has demonstrated that biodiesel fuelled engine deliver less carbon monoxide, unburnt hydrocarbon and smoke emission contrasted with diesel fuel but higher NOx emission. EGR is as viable method to reduce NOx from LHR engine as it brings lower flame temperature and decrease oxygen concentration in the combustion chamber. The primary point of this exploration is to examine the utilization of biodiesel and EGR at the same time to diminish the emissions of all regulated pollutants from diesel engine. For this a single cylinder, water cooled, constant speed direct injection LHR engine was utilized and EGR was produced and fitted in engine. Different emissions, for example, HC, NOx, CO and smoke opacity were measured. The engine parameters were computed from measured data. Read More...

A searching, tracking For Multi-UAV Ad Hoc Networks
-Lovepreet Kaur ; Dinesh Kumar
Cognitive mapping are mental pictures of the attributes of our surroundings. Cognitive maps provide us with a model or guide of our surroundings that we can utilize. When we make Cognitive maps, we regularly prevent data that is not significant or unrelated. This implies that our Cognitive maps can vary from the real environment that we are mapping. cognitive maps make it simpler for us to review data. A cognitive guide is a kind of mental representation which serves a person to secure, code, store, review, and unravel data about the relative areas and characteristics of phenomena in their ordinary or figurative spatial environment. Cognitive maps serve the development and gathering of spatial information, permitting the "mind's eye" to envision pictures to decrease cognitive burden, improve review and learning of data. This sort of spatial intuition can likewise be utilized as a representation for non-spatial tasks, where individuals performing non-spatial tasks including memory and imaging utilization spatial information to help in processing the task. cognitive map is a strategy which has been produced more than a time of time and through its applications and utilization operational researches working on variety of different tasks .These tasks incorporate; furnishing help with organizing confused or complex information solving a problems.

Data Mining Approach to Analyze Crowdsourced Data for Business Analytics
-Mayura Nalawade ; Bharati Dixit
Crowdsourcing has developed as a significant problem solving and information gathering standard which makes use of the Internet. The crowdsourced data available on different blogs, forums and social media websites in the form of customer feedback and reviews is an important source of information for the companies. A Data analyst aims at finding trends, patterns and meaningful insights from crowdsourced data. Taking help of crowdsourced workers to analyze this redundant and huge amount of data is not only tedious but is also time consuming. A solution for this problem is proposed that increases the potential of gain of meaningful insights to a large extent. Data mining approach is used to analyze reviews of four different ecommerce websites based on different performance parameters. This unstructured crowdsourced data is processed and filtered using J48 classifier. 355 fake reviews were eliminated. Remaining truthful data was analyzed and Multiviewpoint based similarity clustering was used in order to remove redundancy, which gave the accuracy of 98.66%. To make crowdsourced data more representative and usable graphs were plotted based on delivery, return, refund and customer care parameter to help the analyst in decision making. Read More...

Behavior of reinforced concrete structure with and without infill
-NANDINI S ; B.S. Suresh Chandra
As rapid growth in population large number of RCC buildings and Steel structures were constructed across the world for residential as well as for public and commercial purposes. Public buildings like Schools, Colleges, Government Offices, Hospitals etc, and commercial buildings like Cinema halls, Shopping mall etc. So the buildings were constructed with RC frames and in the building construction more importance and design consideration is given to RC frames and Masonry infills are considered only to cover the RC frame voids and also to give aesthetic appearance. As the masonry infills are considered only as a void filling element between vertical and horizontal resisting elements of the building frames and assuming that these infills will not resist any loads either axial or lateral. Therefore the masonry infill is not considered in the analysis of frames generally. There is no availability of any kind of realistic and simple analytical models of infill which is the one of the point to skip the infill in the analysis of RC frames. But actually the infill contributes some stiffness to the frame which can reduce the deflection in the frames under lateral load. So this negligence is one of the causes of failure of many multi-storied buildings it may be a RCC building or a steel building. In this study 2D finite element model is developed using FEM software ETABS to determine the behavior of RC framed structures with and without infill under lateral loads especially wind load. In this analysis a bare RC frame is analyzed under wind load, and RC frame with infill that is infill is modeled as a “Equivalent diagonal strut†with single and double struts of concrete and brick properties with varying sizes under lateral load (wind load) is analyzed and compared.

-Sanket Rathi ; Sachin Kandekar; Dr. R. S. Talikoti
Using ANSYS software and experimental work to study torsional behavior of carbon fiber after restrenthening RC beams of M30 grade of concrete, is presented in this paper. Fully wrapped carbon fiber around the RC beams and strips of carbon fiber wrapped at an angle 90° and 45° around the RC beams are the different patterns studied experimentally and analytically. Carbon fiber worked as an external reinforcement. RC beam strengthened with carbon fiber tested for torsional failure; in which lever arms subjected to torque were used. The beam size is 150 mm x 300 mm and of 1.3m in length, designed as per IS456-2000. Three beams are designed for torsion and the twelve beams designed as normal beams in which nine beams are strengthened using different patterns of unidirectional carbon fiber having same properties, to study its torsional behavior. In this experimental work carbon fiber and carbon fiber strips of width 100 mm on all face of beam with 900 and 450 orientations with the longitudinal axis of beam were sticked by using epoxy resin. The effect of different types and configuration of carbon fiber on first crack load, ultimate load carrying capacity and failure mode of the beams were taken into consideration and its study using ANSYS software gives better result for further study.

Optimized Bug Report Triaging Using N-Gram Features and Non-Reproducible Classification
-Shalini Singhal ; Prof. (Dr.) Bhawna Sharma
Testing the product before final release is an inevitable part of any engineering process. Software testing is an activity which is carried out with an intent of finding errors. Testing is carried out as an umbrella activity is most modern software development life cycle models. As time-to-market is a critical constraint for most software, the beta version of the software is released with intent of beta testing. It is the testing which is done by the end user as he/she uses the software. Software bugs are corresponding to all the instants when the software does not meet the specifications or desired functionality. In case of software crashes, there is a provision in most of the software that a bug report is automatically generated and sent to a bug reporting or issue tracking system. Also, in case of other failures, the user can write a description of his/her own about the problem faced. All such bug reports must be handled appropriately to remove the corresponding bug. For software which are publicly viable, and freely distributable across the globe, thousands of bug reports are sent to the issue tracking system, probably corresponding to the same bug. A person in-charge of analyzing the bug reports for checking of duplicity and assigning to appropriate developer is called triager. In this paper, the problem of checking of duplicate bug reports is analyzed based on non-repudiation classification and textual features. The non-repudiation classification is important and critical as the reports for which the corresponding bug cannot be reproduced at client side are of no use. The contribution of this work is the classification of bug reports as being reproducible or non-reproducible using a binary classifier. Support Vector Machine is used for this classification. The traditional textual classifier is augmented with N Gram Features to improve the accuracy of classification. N-gram features relates to the character level representation instead of word level representation. For example, "StringIndexOutOfBoundsException" and "StringIndexOutOfBounds" Exception are two sets which possibly relates to the same event. Proposed model is evaluated over Mozilla-Firefox bug repository. Experimental results indicate a 7% improvement in the kappa measure as compared to the independent approaches proposed by Phuc Nhan Minh and Mona Erfani Joorabchi et.al.. Read More...
