• A hybrid approach to find cloned objects in copy move forged images  
  by Ashish Kumar Chakraverti, Vijay Dhir 
  Abstract: In this paper, we have proposed a new hybrid approach to detecting the cloned object in copy move forged image. Presently images are a very powerful medium to communicate the messages across the world wide web. Social media is used to spread the image as the message in the way of the nuclear reaction. With the help of highly efficient and advanced image editing tools and techniques, images are modified intentionally and then spread over the world wide web. Due to the availability of these advance and efficient image editing tools, the genuineness of images is now highly questionable. There are so many types of image forgery, one of the very popular image forgeries is the copy-move forgery. In this forgery, images are forged by making the clone of objects of the same image with the help of copy past method. There are so many techniques to detect similar objects in the forged image. In our proposed work we have integrated two states of art techniques named Adhoc method and Principle Component Analysis (PCA) based Scale Invariant Feature Transform (SIFT) method and created a new hybrid technique to detect the cloned object in the forged image. Our technique is implemented in the two- step. In the first step, we have preprocessed the object image by the proposed Dynamic Block Size Technique based Local Contrast Modification and Contrast Limited Adaptive Histogram Equalization (DBST-LCM CLAHE) up to desired Peak Signal to Noise Ratio (PSNR) and grey level. After that in the second step, we have integrated Adhoc, and PCA based SIFT algorithm to design a hybrid approach. We have tested our proposed method over CoMoFoD image database. Our proposed method shows the better performance in comparison of the state of art techniques regarding false positive rate(FPR), true positive rate(TPR), and PSNR.

• State Estimation based Target Tracking and Applications of Multi Sensor Data Fusion  
  by David Kondru, Mehmet Celenk, Xiaoping Shen 
  Abstract: Detection, discrimination and tracking of a target under a given dynamic environment is one of the main challenges of an integrated sensory system. A combination of two or more sensors will always provide a better position estimate rather than a single sensor. The advantages of multi-sensor data fusion over a conventional single sensor tracking are presented in this paper. Using state estimators from simple linear rustic filters to a complex nonlinear filter, the tracking of target performing three different motions with sensor noises are presented in this paper. RADAR and the infrared search and track (IRST) are the two sensors considered based on which a complete mathematical modelling and simulation of the sensor measurements and tracking methodologies are utilised. The extension of the paper also presents the image fusion techniques using a widely known technique known as principle component analysis method. The RMS errors in position as well as image error measurements are performed that shows the superiority of the multi sensor data fusion process.

• Data Preprocessing Based On Missing Value and Discretization  
  by Neeta Yadav, Neelendra Badal 
  Abstract: In the real world, data is not available in the appropriate form for mining or extracting information from this. Generally, real-world data is incomplete, inconsistent and dirty so it is very necessary to process data smartly according to the requirement of the dataset. Preprocessing is one of the most crucial steps in data mining and most of the time spent in this about 60% of the time. Unprocessed data takes lots of time in mining. End-user wasted lots of time in getting the desired result. So it is very necessary to process data according to the specific dataset by applying techniques of processing and thereby it reduces the overall mining time, the end user gets the desired result more fastly. In this paper preprocessing of missing value and discretization has been done. Preprocessing of missing value handle by three techniques that is a deletion, Replacement by mean or averages, and prediction method. From these three techniques user opt the best technique for handling missing value, which gives maximum accuracy and takes less time for preprocessing. After handling the missing value, discretization is done for data reduction so it minimizes the preprocessing time.

  by Jayasri Angara, Srinivas Prasad, Sridevi Gutta 
  Abstract: DevOps is an outgrowth of agile practice and evolved to manage the continuous change. The goal is to shorten the project timelines, increase productivity, without impacting business and quality. Automation has become one of the key enablers for success. However, test automation gets little time. This poses a challenge to managers whether to automate the test function or not. Managers need to take swift go/no-go decision. The objective of this paper is to develop a predictability model for test automation project feasibility. Authors conducted a literature and practitioner’s survey and identified 21 key factors which determine the viability of a project. Authors surveyed 38 test automation projects and created a dataset. A custom simulation model was developed, augmenting the dataset with 23,407 more records. Authors attempted to predict the success using machine learning algorithms. Further, factor analysis was conducted to reduce the number of factors for operational simplicity.

• Parameter correlation analysis and minimum volume design of a helical gear implementing PSO algorithm  
  by Edmund S. Maputi, Rajesh Arora 
  Abstract: Gears are important mechanical elements in the assembly and functionality of a machine. The application of optimisation techniques in engineering design and gear technology has increased due to the accessibility and advancement in computational resources. Furthermore, current research trends reflect a keen interest in volume minimisation of gear systems. In this research work, a helical gear volume model is investigated. Particle swarm optimisation algorithm is applied and the results are compared and validated using an analytical method and geometric modelling software. Optimal design theory is discussed including the interrelation of concepts such as design, analysis and optimisation reflecting the need to analyse the influence of parameters on objectives. Experimental runs using genetic algorithm, firefly algorithm and teaching learning-based algorithm were also performed with statistical analysis. Parameter variation studies were also performed on each variable against the objective, minimum volume. The results of this research work, shows that module, pinion tooth number and face width are important parameters for the minimisation of gear weight with 38%, 32% and 12% contribution to variation, respectively.

• Requirements’ Complexity Ranking using Natural Language Processing and Complexity Class Correlation with Defect Severity  
  by Mukundan Sundararajan, Priti Srikrishnan, Kiran Nayak 
  Abstract: This paper addresses the risks to delivery schedule and product quality from non-periodic temporal detection of high severity defects in software projects. The non-periodicity in time and lack of a time boundary in detecting severe defects primarily stems from subjective scheduling of development and testing of product features. One solution is to objectively determine complexity and ranking of requirements to drive the project development and test sequence that uncovers high severity defects early in the life cycle phases. Requirements complexity is strongly correlated with defect severity as measurements show. Applying natural language processing, key words are identified in the given set of requirements, their weights measured to determine the complexity class distribution and ranking that drives the scheduling. The complexity and defect correlation-based sequencing mitigates the risks by discovery of high severity defects in a temporal saw tooth pattern providing the project team sufficient time to fix defects and mitigate the risks.
  Keywords: Requirements complexity; Requirements ranking; Requirement complexity classes; Natural language processing; NLP; Defect severity correlation; defect spatial distribution; defect temporal distribution.
