by Anbesh Jamwal, Ankur Aggarwal, Sumit Gupta, Parul Sharma
Abstract: In todays competitive market, lean philosophy has a vital role to play which is mainly governed by a reduction in cost, ameliorated quality, and higher expectations of customers as well as superior productivity. It has been globally witnessed that the companies which implement lean manufacturing in their system result into improved productivity and better customer satisfaction, along with the cost reduction. Lean manufacturing is the most important productivity improvement tool. The aim of this research is to identification and confirmation of the barriers to lean implementation in small-scale industries in the Himachal Region (India) and to build up a relationship between the barriers. A Total Interpretive Structural Modeling approach is applied to identify the relationship of various barriers. It is evident from the research that the cost of facilities is a major barrier to implementing lean in the small-scale industries. However, the government gives the financial support for the small-scale industries in Himachal Pradesh.

Incorporating carbon emissions in queuing models to determine lot sizes and inventory buffers in a supply chain
by Petrus Setya Murdapa, Nyoman Pujawan, Putu Dana Karningsih, Arman Hakim Nasution
Abstract: In this paper, we present a supply chain model that considers both inventory-related costs and emissions. We used the queueing-based performance model wherein emissions in three stages of supply chain activities are captured. The model was solved by the decomposition approach. For model validation, we have used a discrete event simulation. The computation results show that the two results, i.e., the decomposition approach and the simulation, are very close, indicating the accuracy the approach that we used. Experiments were conducted to test the applicability of the model. The numerical examples show that the change in parameter values is not always responded the same way by the total inventory-related costs and the emission costs, indicating the importance of including these two response variables in the model.
Keywords: Carbon emission; inventory buffering; lot sizing; performance model; supply chain.

Entrepreneurial passion facing its ecosystems obstacles: The case of Tunisia
by SAMIRA BOUSSEMA
Abstract: Entrepreneurship is one of the most appropriate remedies to the various economic crises. It is presented as a complex process that faces several barriers, thereby inhibiting a projects implementation phase. In fact, after a careful review of the literature, we noticed that empirical research on reasons behind unimplemented entrepreneurial projects are very rare, suggesting a failure in modeling the process in general and the pre-start phase in particular. In this paper, we try then to identify the main constraints to entrepreneurial passion in Tunisia by studying a representative sample of project promoters who have been unable to carry out their business projects. Using structural equation methods, we found that these promoters face barriers like a lack in entrepreneurial training and services provided by supporting organizations.
Keywords: Entrepreneurial passion; unimplementation of projects; Structural modeling.
Implementing just-in-time (JIT) based supply chain for the bulk items in an integrated steel plant
by Ram Naresh Roy
Abstract: Due to increasing global competition, organizations are continuously improving their operational practices and cost efficiency to get a competitive edge. This paper involves a case study in ABC Steel plant (anonymised) dealing with a huge amount of bulk-materials handling and transportation, and proposes a JIT-based model of handling and transporting which may lead to potential cost savings. The paper discusses the important requirements of JIT procurement and transportation through a literature review. The existing system of ABC Steel plant has been studied and modelled as a pull-system, and an MRP model has been used to calculate the amount of various raw materials needed for making the hot-iron or steel. The total costs of transporting bulk materials from various sources for steelmaking in the existing system (model-1) and the proposed JIT system (model-2) have been calculated. The differences between the two indicated the potential savings for different levels of safety-stock and different levels of JIT implementation.

Framework to Identify a Set of Univariate Time Series Forecasting Techniques to aid in Business Decision Making
by IRAM NAIM, Tripti Mahara
Abstract: Forecasting is generally involved in business activities to anticipate or predict the future. With availability of numerous techniques and models, forecasters regularly face a genuine issue to select the most appropriate technique for different time series available in an organization. Most of the time, it is not possible to find one technique that can be used for all-time series as the selection is dependent upon the characteristics of a time series. Hence, the research proposes a selection tree to aid in decision making based upon availability of type of dataset and time series characteristics. The framework is validated using four real case studies. This study also presents advancement to existing forecasting method selection tree by exploring a new dimension of complex seasonal pattern for long time series.
Keywords: Univariate Time Series; Time series Pattern; model selection; trend analysis; seasonal data; complex seasonality; long time series.
Innovativeness, Environment and Performance of Small and Medium-sized Enterprises (SMEs) in the Manufacturing Sector in Malaysia
by Mandy Mok Kim Man, May Chiun Lo
Abstract: This study examines innovativeness and environmental factors that can influence the performance of SMEs (small and medium-sized enterprises) in the Malaysian manufacturing sector. A theoretical framework is developed, based on innovativeness, environment and SMEs performance. The present study examines the fundamental nature of innovativeness and relates these various elements of innovativeness to SMEs performance. Firstly, in the Malaysian context, the government interferes in the market through new business policies, increasing or decreasing the interest rate, controlling money supply and implementing competition policy law. Secondly, the role of government has also been neglected in most previous research in measuring the environment influences on business in spite of their importance in determining the environment indicators, such as, environmental uncertainty and intensity of competition. The present study shows that the innovativeness has significant impact on SMEs performance and the environment variables have moderating effect on the relationship between the innovativeness and SMEs performance.
Keywords: innovativeness; SMEs; environment; performance; technology; entrepreneurship.

Performance study of Routing Protocols based on node mobility in MANETs
by Younes BEN CHIGRA, Abderahim GHADI, Mohamed BOUHORMA
Abstract: Mobile Ad Hoc network (MANET) is established by a set of smart mobile nodes without any central intelligence. Hence, nodes auto-discover their surrounding and establish needed links between source and destination node. Moreover, mobile nodes change arbitrary their position, which lead to frequent link failure. Therefore, the dynamic behaviour of nodes has a drastic impact on networks performances such as end-to-end delay, packet loss ratio and traffic control that is generated during route update process. Consequently, the main issue in MANETs operations is the design of an efficient routing protocol able to deliver required quality of service in case of nodes mobility and manage the intrinsic limitation of wireless networks, like scares bandwidth, limited energy and processing capabilities. The purpose of this paper is to study the impact of nodes mobility on routing performances and look forward an appropriate optimisation that might enhance efficiency of routing protocol in high dynamic environment.

Architecture of a Decision Support System Based on Big Data for Monitoring Type 2 Diabetics
by Boudhir Anouar Abdelhakim, Ben Ahmed Mohammed, Fellaji Soumaya
Abstract: Type 2 diabetes is one of chronic diseases that require continuous and real-time monitoring to prevent the occurrence of complications. On the one hand, the doctor must have information about the patient's daily life (vital signs, stress, sedentary lifestyle, physical activities, nutrition, etc.). On the other hand, the prescribed treatment must be evaluated each time to test the validity of the diagnosis. To achieve this goal, a decision support system based on the Big Data Mining technology must be designed in order to have a centralized knowledge of diabetics. This system will improve the quality of monitoring and treatment from the different data collected. Thus, this paper presents an architecture of a decision support system allowing doctors to monitor the health status of their patients, based on data collected from different resources, in order to enrich the knowledge database and prescribe new treatments based on similar cases and experiences of doctors and patients belonging to this system.

MultiPrime Cloud-RSA: A Fast Homomorphic Encryption Scheme for Data Confidentiality Protection in Clouds
by Khalid EL MAKKAOUI, Abderrahim Beni-Hssane, Abdellah Ezzati
Abstract: Concerns over data confidentiality are amongst the main barriersrnlimiting the widespread adoption of cloud solutions. Indeed, scientists haverninvented a new promising form of encryption, homomorphic encryption (HE),rnwhich can be considered as a powerful tool to get over these concerns. Sincerncloud environments are more vulnerable to attacks and since cloud consumersrnfrequently access to cloud computing services using light-weight devices, the HE schemes must be promoted, in terms of security level and running time, to operate efficiently. In El Makkaoui et al. (2017), we boosted the normal RSA cryptosystem at security level, Cloud-RSA. In this paper, we suggest a new fast variant of the Cloud-RSA scheme, MultiPime Cloud-RSA, to accelerate its decryption process. The variant uses a modulus of the form n = p1p2...pk for k>= 2 and employs the Chinese remaindering to decrypt. Theoretical and simulation results show that the new variant offers a large decryption speed-up over the Cloud-RSA scheme whilst maintaining a recommended security level.

Training and Evaluation of TreeTagger on Amazigh Corpus
by Amri Samir, Zenkouar Lahbib
Abstract: Part of Speech (POS) tagging has high importance in the domain of Natural Language Processing (NLP). POS tagging determines grammatical category to any token, such as noun, verb, adjective, person, gender, etc. Some of the words are ambiguous in their categories and what tagging does is to clear of ambiguous word according to their context. Many taggers are designed with different approaches to reach high accuracy. In this paper we present a Machine Learning algorithm, which combines decision trees model and HMM model to tag Amazigh unknown words.
In case of statistical methods such as TreeTagger, this will have added practical advantages also. This paper presents creation of a POS tagged corpus and evaluation of TreeTagger on Amazigh text. The results of experiments on Amazigh text show that TreeTagger provides overall tagging accuracy of 93.19%, specifically, 94.10% on known words and 70.29% on unknown words.

Game Theory based Analysis of Inter-cluster Communication in a DRHT Network
by El Arbi Abdellaoui Alaoui, Mustapha El Moudden, Khalid Nassiri, Said Agoujil
Abstract: The system performance of the delay tolerant networks (DTN) can be significantly improved by using the DTN routing hierarchical topology (DRHT) which incorporates three fundamental concepts: ferries messages, ferries routes and clusters. The intra-cluster routing is managed by the cluster head, while the inter-cluster routing is managed by the ferries messages. In this paper, we analyse the behavior of data dissemination problem of ferries in the DRHT. More specifically, in order to analyse the inter-cluster communication in the DRHT, we formulate non-cooperative game and game stochastic which model the behavior of the ferries.

Towards a ubiquitous students response system for monitoring learning performances
by Aimad Karkouch, Hajar MOUSANNIF, Hassan Al MOATASSIME
Abstract: Receiving feedbacks from students about their learning experience is a key part of any pedagogical approach. Students feedbacks could be retrieved in a variety of ways using various Students Response Systems (SRS), however, existing SRS suffer from lack of seamless integration into learning environments, becoming a potential source of distraction for the learning process. We propose a Ubiquitous Students Response System (U-SRS) that is capable of continuously and seamlessly monitoring various students learning performances features, making sense of them and providing insights for teachers, enabling them to adapt their pedagogical approach according to their students immediate needs. The proposed U-SRS takes advantages of machine learning and the Internet of Things paradigm to enable its services in connected classrooms. We present our solutions design, its architecture and features used to build learning performance predictive models along with implementation and various prototypes. Finally, we highlight the advantages of U-SRS over existing solutions.

Improving smart learning experience quality through the use of extracted data from social networks
by Kenza Sakout Andaloussi, Laurence Capus, Ismail Berrada, Karim Boubouh
Abstract: With the development of smart cities applications, the need for smart learning is increasing. Although current systems are supposed supporting smart learning, they do not really meet the expectations. In fact, for learner models, data are still mostly gathered through questionnaires and are not predicted, then standards are not satisfied. Regarding the domain model, it appears that collaborative learning is not considered. Finally, for the adaptation process, it depends on two main criteria namely the learning style and the knowledge level, in addition, it concerns only one or two of these aspects: content, navigation or presentation. This paper explores the feasibility of learner modelling based on data extracted and inferred from social networks, according to the IMS-LIP specification. An adaptive learning system has been developed on the basis of this innovative approach. The first results confirm that this new way can improve the smart learning experience.

Detection of drivers alertness level based on the Viola & Jones method and logistic regression analysis
by Samir ALLACH
Abstract: The analysis of the face elements state is a crucial step for the drivers alertness level detection. In this article, we propose a drivers assistant system that activates alarms to alert the drowsy and/or tired driver.
Our proposed system contains the following steps: firstly, the recognition of the facial elements (eyes, mouth). Secondly, the system determines the states of the mouth and eyes. Finally, it triggers the alarm in the case of the danger. For the extraction and recognition of the face and its elements (eyes, mouth), we use the Viola & Jones method and we also use Logistic Regression analysis that takes the supplied vector image to determine if the driver is in drowsiness and / or fatigue.
The tests performed on the real video sequences, using an Embedded System, provide good results and may function in real time

A memetic algorithm for fleet size and mix vehicle routing problems with electric modular vehicles
by Dhekra Rezgui, Jouhaina Chaouachi Siala, Wassila Aggoune-Mtalaa, Hend Bouziri
Abstract: This work deals with an extension of the well-known vehicle routing problem with time windows (VRPTW), where the fleet consists of electric modular vehicles (EMVs). The main drawback of managing electric vehicles is that they have a limited range. Here the vehicles are modular which means that payload modules are carried by a cabin module and can be detached at certain customer locations allowing the rest of the vehicle to continue the tour. This can also permit to recharge the battery of some modules to further capitalise on the gained energy. To tackle the resulting research problem, a comprehensive mathematical formulation is proposed to take into account the
multiple constraints linked with the modularity, the electric charging, time windows to serve the customers and capacity issues. Due to the NP-hardness of the problem, a memetic algorithm is implemented and tested for designing good quality solutions in reasonable computational times. Extensive computational experiments carried out on some benchmark instances show the effectiveness of both the problem formulation and the memetic algorithm.

OBJECT CATEGORIZATION AND FLAME APPREHENSION
by Santhosh Kumar B, Velliangiri S, Ajayan J
Abstract: Object categorization is a customary errand of PC observation which includes deciding if a picture contains some particular class of question. The thought is firmly related with acknowledgment, arrangement, and misgiving. There are numerous techniques to speak to a division of articles, from shape investigation, or neighbourhood inscriptions, for example, SIFT, and so forth. The possible point is to extricate semantics from video to be utilized as a part of larger amount action examination undertakings. Arranging the kind of an uncovered video question is a significant advance in accomplishing this objective. Nonetheless, late research has demonstrated that question groups and their areas in pictures can be found in a freely way too. Our contemporary question arrangement calculation influences utilization of the closer view pixel to delineate to every individual associated area to make a blueprint for the protest. Customarily fire sensors which sense the nearness of specific particles created by smoke and fire by photometry were utilized to recognize fire. Normal sensors mean to detect particles, accordingly, an essential shortcoming of point locators is that they are separate limited and decay in open spaces. In this paper we depict the computational models utilized in our way to deal with achieve the objectives indicated previously

ENHANCING SECURITY BY TWO WAY DECRYPTION OF MESSAGE PASSING OF EMR IN PUBLIC CLOUD
by PRATHAP R, MOHANASUNDARAM R
Abstract: Encryption is one of the most critical and mandatory technique to provide security in outsourced data. Message passing is the most unsecure place of transfer of dangerous information's, and this message passing is made the end to end encryption to avoid a centralized security agent to access the data. Existing methods of encryption only provide end to end encryption which is not feasible for certain situations like implementing authentication. When the end to end encryption is made, the messages are always not known to the central authentication agent like CBI, in this paper, we provide a two side decryption algorithm that can be decrypted by two entities (one receiver and the other is the central authentication agent). Thus improving the message passing security by allowing the centralized authentication agent to read the transferring words. We implemented this two-way decryption in trip database dataset, and the experiment results prove that our proposed algorithm improves the security of message passing of Electronic Medical Records in public cloud while comparing with existing encryption algorithms.

by P. Chitra, M. Mary Shanthi Rani
Abstract: The advancement of medical field has witnessed tremendous growth with state of the art imaging technologies for accurate diagnosis, which in turn demands efficient storage of medical images. Further enhance the image quality RVQ is implemented in the proposed method. The proposed work aims at developing an effective algorithm for compressing medical images exploiting the advantages of Block Truncation coding(BTC) and Residual Vector Quantization(RVQ). The advantage of the Block Truncation Coding (BTC) is twofold: 1. It is simple to implement and 2. Involves less computational complexity. RVQ is used to enhance the quality further. In the proposed method, the input image is compressed using BTC in the first phase. The residual error out of first phase is subjected to RVQ in the second phase. The novel feature of the proposed method is the adaptive procedure of RVQ based on the variance of residual vectors. High variant residual vectors are subject to vector quantization and low variant vectors to scalar quantization respectively. Furthermore, the residual values are normalized to positive values, so as to preserve their sign, before quantization. Experimental results show the superior performance of the proposed method in terms of compression metrics.

An Incremental Approach for Hierarchical Community Mining in Evolving Social Graphs
by Keshab Nath, Swarup Roy, Sukumar Nandi
Abstract: Community members which are highly connected with each other inside a community tends to create sub-communities, commonly termed as intrinsic or hierarchical communities. Finding intrinsic communities help us to reach out specific user needs, understanding the network dynamics and unveiling the functional and hidden aspects in the network, which is difficult without unveiling intra and inter-community all kinds of relationship. With the passage of time, members of a community may acquire different interests, leads to movement of members within different communities. Frequent changes in the relationship of members towards a community make the task of community
detection even more challenging. In this work, we propose a new community detection method, embedded communities from evolving networks (ECEnet), for handling intrinsic communities in evolving networks. We adopt a density variation concept to detect the intrinsic communities in growing networks. We use a new membership function to measure the contiguity of a member towards a community. We use both synthetic and real-world social networks for our experimentation. Experimental results reveal that ECEnet is successful in detecting intrinsic or hierarchical communities in a dynamic scenario.

Product recommendation system using optimal switching hybrid algorithm
by P. Bhuvaneshwari, A. Nagaraja Rao
Abstract: With the advent of e-commerce on the internet era, people prefer to do online shopping by just clicking the corresponding website. E-commerce website holds a million of products with a lot of information about it. As it holds the wide variety of products in the same category, the customer feels difficult in choosing the desired one they exposed to. To overcome this information overload issue and to attract the customers, the term recommendation system was introduced in an e-commerce system. The recommendation system works as a heart in the business strategy of e-commerce companies like Amazon, Flip-Kart, ebay, etc. initially, collaborative filtering technique was utilised by most of the recommendation engine for reaching out the customers by providing the right product and the services at the right time. Even though it is popular and highly valuable, it faces the challenge of recommending the products for the new user (cold start problem). In this study, we propose an optimal switching hybrid approach (OSHA) to overcome the above problem where demographic filtering technique is employed to find the similarity of users and the combination of CF prediction mechanism provide the basis for processing the recommendations. The OSHA is the combination of collaborative filtering and demographic filtering techniques where it switches between the context depending on the scenario. Similarity prediction measure and K nearest neighbour algorithm are used to predict the similar kind of users with size K. The experimental results show that the proposed algorithm performs better and improves the performance of the recommender system than the standalone technique.
Keywords: e-commerce; collaborative filtering technique; cold start problem; optimal switching hybrid approach; OSHA; demographic filtering technique; k-nearest neighbour algorithm.
Changed Detection of Landsat 8 Imagery using Object Based Image Analysis with Particle Swarm Optimization
by Amitabha Nath, Amos Bortiew, Goutam Saha
Abstract: This paper addresses the problem of classification of hyperspectral remote sensing image and detection of any changes in the land use pattern using it. Traditional pixel based classification approaches often fail to achieve acceptable accuracy in classifying Landsat images because of its complexity. Therefore, present work aims to apply object based-image analysis (OBIA), which is a concept that combines segmentation and classification together into one unit. We propose a hybrid OBIA architecture, augmented with particle swarm optimisation (PSO) technique to fine tune different hyperparameters involved with it. We present its success on a classification problem where two sets of landsat-8 images captured in the year 2016 and 2017 are considered as input and OBIA is applied for classifying the images into four major land use classes and detect any changes in these classes over the period of time. The results are then compared with best pixel based classification approach known as random forest (RF) classifier to determine its effectiveness in classification of hyperspectral images. Statistical measures like precision, overall accuracy and kappa coefficient are used as a parameter for comparison.
Keywords: Landsat 8 image; RF; object based-image analysis; OBIA; particle swarm optimisation; PSO; changed detection; accuracy assessment.

by Vinothkanna Rajendran, Vijayakumar Thangavel, Prabakaran Narayanasamy
Abstract: Physically challenged persons may face many difficulties in the present modern environment as most of the commercial facilities and utilities for a day to day life is designed for normal people to lead a sophisticated life. Particularly people physically disabled face struggles in escalators in malls and public transportation places. It is very difficult for the disabled individual to be identified as one among in a large crowd and they normally feel unconformable to step inside in a running escalator. This research work proposes a novel method to identify the physically challenged persons from a large crowd by their nature of legs, walking pattern and hand sticks and provide necessary preference for them to get inside the escalators. Gait automation and detection mechanism is used for person identification for all gait events and deep learning based neural network (DLNN) is used for learning the patterns and making the system to automatically identify the physically challenged. Experimental results shows that the proposed system automatically measures all the angle of gait events with an accuracy level of 95.4% and thus offers a cost effective solution for gait kinematic analysis for disabled peoples.

Impact of Organizational Justice on Perception of Ability-Job-Fit in Changing Environment
by MRINALI Tikare
The study aims to investigate the association/relationship among Procedural Justice, Distributive Justice and Perceived-Ability-Job-Fit.
This quantitative study has adopted the objectivism approach and is deductive in nature. Data were collected by using Multi-stage Probability Sampling Method from 274 Class-I employees working in Multinational General Insurance Company a subsidiary of Central Government of India. The scales developed by Sweeney & MaFarlin (1997) for Procedural Justice (PJ) & Distributive Justice (DJ) and Abdel-Halim (1981) for Ability-Job-Fit was selected. The techniques used for data analysis were Descriptive Statistics, Pearson Correlation and Multiple Regression.
The respondents have positive perception about their ability to perform the job and they are optimistic about the fairness of prevailing procedures and distribution of rewards followed by their organization which is indicated by high mean scores. The positive DJ & PJ perceptions proportionately increase the perception of Ability-Job-Fit. The result of Multiple Regression analysis indicated that two independent variables (DJ & PJ) explained the variance in Perceived-Ability-Job-Fit (Dependent Variable). The perception of PJ is making a statistically significant unique contribution to the prediction of the Perceived-Ability-Job-Fit.
The findings will be useful for employees to reduce stress by understanding the Fit Concepts. The HR practitioners can predict the behavior of their employees by executing the fairness practices in the system. The top-management can win trust and thereby expect support from their employees, even during dynamic/volatile business environments by implementing appropriate PJ in the organization.
For the first time, the study has attempted to establish a direct relationship between fairness perception and ability fit/congruence perception of employees. It may lead the future researchers to work in-depth on this model. The analysis of the study did not consider the effect of demographic variables. It should be noted that there are several concerns while generalizing the findings of this study.
Keywords: Distributive/Procedural Justice; Perceived-Ability-Job-Fit; experienced government employees.
Price Discovery and Volatility Transmission in the Spot and Futures Market of Pepper: An Empirical Analysis
by Asha Nadig, Viswanathan T
Abstract: Pepper, the king of spices, is one of the oldest and widely traded spices across the world over many centuries. As a commodity traded in the spot, futures and export market, global demand and supply play a crucial role in shaping pepper price and volatility. As price risks are integral to farmers and traders, forecasting successive prices will be of great help to them. The price risk can be minimised through effective hedging. The futures market provides a platform for both hedging and speculation. Hence understanding the relationship between spot and future market is essential for the traders of commodities. Understanding the relationship between the two markets include price forecasting, price discovery and volatility spill over between the spot and futures market.
This paper examines the price discovery mechanism and volatility transmission between the spot and futures prices of pepper. Applying the statistical, seasonal variation and econometric models for forecasting, forecasting accuracy is tested. By applying the simple linear regression model, the study concluded that the subsequent price of pepper in the spot market cannot be predicted appropriately. The Holt Winters model gives biased estimate of future prices. The goodness of fit analysed through the Akaike information criterion (AIC) gives better values of forecasting. The ARIMA model is the appropriate model to forecast the price of pepper.
Keywords: Forecasting; Price discovery; Cointegration; Volatility spill over.

Comparative Study on IDS using Machine learning approaches for Software Defined Networks
by Muthamil Sudar K, Deepalakshmi P
Abstract: Software Define Networking (SDN) is an emerging network approach that separates the data plane from control plane and enables programmable features to efficiently handle the network configuration in order to improve network performance and monitoring. Since SDN contains the logically centralized controller which controls the entire network, the attacker mainly focuses on causing vulnerability towards the controller. Hence there is a need of powerful tool called Intrusion Detection System (IDS) to detect and prevent the network from various intrusions. Therefore, incorporation of IDS into SDN architecture is essential one. Now a day, Machine Learning (ML) approaches can provide promising solution for the prediction of attacks with more accuracy and with low error rate. In this paper, we surveyed about some machine learning techniques such as Naive Bayes, Decision tree, Random forest, Multilayer Perceptron algorithms for IDS and compare their performance in terms of attack prediction accuracy and error rate. Additionally, we also discussed about the background of SDN, security issues in SDN, overview of IDS types and various machine learning approaches with the knowledge of datasets.

A Novel Method for Predicting Kidney Diseases Using Optimal Artificial Neural Network in Ultrasound Images
by Balamurugan S.P., G. Arumugam
Abstract: The main aim of this research is to design and develop an efficient approach for predicting ultrasound kidney diseases using multiple stages. Nowadays, kidney disease prediction is one of the crucial procedures in surgical and treatment planning for ultrasound images. Therefore, in this paper, we propose a novel ultrasound kidney diseases prediction using the artificial neural network (ANN). To achieve the concept, we comprise the proposed system into four modules such as preprocessing, feature extraction, feature selection using OGOA and disease prediction using ANN. Initially, we eliminate the noise present in the input image using the optimal wavelet and bilateral filter. Then, a set of GLCM features are extracted from each input image and then we select the important features using oppositional grasshopper optimization algorithm (OGOA). To classify the image as normal or abnormal, the proposed method utilize an artificial neural network (ANN). The performance of the proposed method is evaluated using accuracy, sensitivity, and specificity. The experimentation results show that the proposed system attains the maximum accuracy of 95.83% which is high compared to existing methods.

Recurrent Neural Network based Speech Recognition using MATLAB
by Praveen James, Mun Hou Kit, Chockalingam Aravind Vaithilingam, Alan Tan Wee Chiat
Abstract: The purpose of this paper is to design an efficient Recurrent Neural Network (RNN) based speech recognition system using software with Long Short-Term Memory (LSTM). The design process involves the implementation of speech acquisition, pre-processing, feature extraction, training and pattern recognition tasks for a small vocabulary sentence recognition system using RNN. A vocabulary of 80 words which constitute 20 sentences is used to train and test a vanilla LSTM network. The depth of the layer is chosen as 20, 42 and 60 and the accuracy of each system is determined. The results reveal that the maximum accuracy of 89% is achieved when the depth of the hidden layer is 42. Design complexity and processing time are considered when the signal acquisition, pre-processing, feature extraction, and training algorithm are implemented. In this paper, there are 5 layers namely, the input layer, the fully connected layer, the SoftMax layer, the output layer and one hidden LSTM layer that can be increased for more complex design requirements. The LSTM network stores previous values and is the core component of the speech recognition system. Since the depth of the hidden layer is fixed for a task, increased performance can be achieved by increasing the number of hidden layers. However, the processing time increases as the number of layers increase which necessitates a dedicated hardware device.

S-Transform Based Efficient Copy Move Forgery Detection Technique in Digital Images
by Rajeev Rajkumar, Sudipta Roy, Manglem Singh
Abstract: Copy-move Forgery (CMF), which copies a part of a picture and pastes it into another location, is one of the common strategies for digital image tampering. Due to the arrival of high-performance hardware and the compact use of image processing software, empowers creating image forgeries easy that are undetectable by the naked eye. For CMF detection, we suggest an efficient and vigorous method that could take care of numerous geometric ameliorations including rotation, scaling, and blurring. In the projected CMF detection system, we use Stock Well Transform (S-Transform) which hybrids the advantages of both Scale Invariant Feature Transform (SIFT) and Wavelet Transform (WT) to extract the key points and their descriptors from the overlapped image blocks. Furthermore, Euclidean distance (ED) between the overlapped blocks are measured to detect the similarities and to identify the tampered or forged region in the image. Besides, a novel Fuzzy min max Neural Network based Decision Tree (FMMNN-DT) classifier is used to recognize the duplicated regions in the forgery image. The proposed system is tested and validated using MICC-F220 dataset and we present comparison among the proposed outcomes with some existing ones which ensure the significance of the proposed.

by Suja C. Nair, Sudheep Elayidom, Sasi Gopalan
Abstract: With the expanding number of vehicles on the road is creating substantial traffic that is hard to control and maintain safety, particularly in extensive urban areas. To estimate the traffic density several works were carried out in the past. However, they are inappropriate and expensive due to the dynamics of traffic flow. Here we intend to use CDR to distinguish the traffic density location and to track the location of the mobile user. In our proposed method to discover the density scope of the traffic, we are using two algorithms called k-means clustering and the k nearest neighbor classification algorithms. The proposed technique will be tested among five different locations during the weekdays and the weekends, which show the noteworthiness of the proposed algorithm and show that our technique has high accuracy.

Necessity of source extension and drain extension has been uninvolved, resulting less fabrication cost and higher concentration of transistors in same chip area. Another improvement is removal of gate spacer, resulting cutting down of process cost. Both the conventional MOSFET and the proposed one have been simulated by Sentaurus TCAD toolkit for 7 nm technology generation. The performance of the proposed transistor has been found satisfactory compared to the conventional MOSFET as per the guidance given in International Technology Roadmap for Semiconductors or ITRS 2013 version.

A Supervised Multimodal Search Re ranking Technique using Visual Semantics
by Nikhila T Bhuvan, M. Sudheep Elayidom
Abstract: The multimedia content in a webpage is usually given least importance in webpage ranking. A better user satisfaction could be achieved if the web pages are ranked based on multiple modalities rather than just depending on the textual content. A better ranking of the web pages is proposed using natural language descriptions of images along with the textual content in a webpage is being proposed. The inter-modal correspondences between text and visual data is learned using the Convolutional Neural Network assisted by the datasets of images and their sentence descriptors. The model is based on Convolutional Neural Networks over images to generate the image descriptor and Dandelion API for their similarity measure with the Query. The image description is algorithmically generated rather depending on the image annotations present. Finally, it has been proven that the re-ranked web pages using the generated descriptions significantly outperform the state of art retrieval models.
Keywords: Automatic image annotation; Convolutional Neural Networks; image descriptor; multimodality search; search re ranking; semantic similarity.
Intelligent Systems for Volumetric Feature Recognition from CAD Mesh Models
by Vaibhav Hase, Yogesh Bhalerao, Saurabh Verma, G. Vikhe Patil
Abstract: This paper presents an intelligent technique to recognize the volumetric features from CAD mesh models based on hybrid mesh segmentation. The hybrid approach is an intelligent blending of facet based, vertex based, rule-based, and artificial neural network (ANN) based techniques. Comparing with existing state-of-the-art approaches, the proposed approach does not depend on attributes like curvature, minimum feature dimension, number of clusters, number of cutting planes, the orientation of model and thickness of the slice to extract volumetric features. ANN based intelligent threshold prediction makes hybrid mesh segmentation automatic. The proposed technique automatically extracts volumetric features like blends and intersecting holes along with their geometric parameters. The proposed approach has been extensively tested on various benchmark test cases. The proposed approach outperforms the existing techniques favorably and found to be robust and consistent with coverage of more than 95% in addressing volumetric features.
Keywords: CAD mesh model; hybrid mesh segmentation; volumetric feature recognition.

Rendezvous Agents-based Routing Protocol (RARP) for delay sensitive data transmission over wireless sensor networks with mobile sink
by V.T. VENKATESWARLU, P.V. NAGANJANEYULU, D.N. RAO
Abstract: The data collected by the sensor nodes will be transferred to sink in traditional wireless sensor networks. The data transmission routes either direct or through the route established using intermediate nodes in between source sensor and sink. Due to the constrained energy reserves of the sensors, a transmission route should operate with minimal energy that tends to longevities the survival of the network. The other critical requirement of these sensor networks is the transmitting delay sensitive data with the ability of fault tolerance and ordering the data to be transmitted that is done by the factors involved to define the priority of that data. The numerous contributions observed in contemporary literature are dealing with the objectives stated. However, these objectives are still grabbing the attention of the present research domain, which is due to the phenomenal changes in network topologies, and the dense span of the network regions. This manuscript endeavored to portray a novel routing strategy to transmit delay-sensitive data from sensors to sink that aimed to achieve fault tolerance, priority-based transmission and longevities the network lifespan. The network context of the proposal is a sensor network with the mobile sink. A novel routing is portrayed that partitions the network area into regions and establishes rendezvous agents for the mobile sink at all of these regions and defines a method to order the areas which is followed by the mobile sink to visit the regions. The process of ordering the regions is furbished under many quality of service objectives portrayed in this manuscript. The performance of the proposed model assessed through simulation study and the same is compared with other contemporary model having similar objectives. The energy consumption efficiency under optimal packet delivery with minimal latency is the objective considered for the performance analysis.

Design of Data scoring model for Big Data
by Ranjan Kumar Dash
Abstract: The huge volume and variety of data stored in big data provide more accurate predictive platform for the users. However, the decision-making process becomes a tedious task due to requirement of much computational time and memory to access them. Thus, a solution to the said problem is data scoring that provides the selection of only those variables or features that impact the decision-making process to a greater extend. To cater the need of an efficient data scoring model, the work carried out in this paper proposes a new data scoring model for big data. The proposed model uses Adaptive LASSO as the statistical method. The steps involved in the design of the proposed model are outlined with proper explanation. The model is trained and tested by k-fold cross validation technique. The performance of the model is measured using ROC curve. The model is simulated using R and is applied on three distinct data sets. To make a comparison with LASSO, LASSO is also applied on these data sets. The simulated results reveal that the adaptive LASSO performs better than LASSO for large sized data sets.

Rapid Retrieval of Secured Data from the Sensor Cloud using a Relative Record Index and Energy Management of Sensors
by Geetha S, Deepalakshmi P
Abstract: A massive amount of data is produced by sensors. The data eventually finds a place in the cloud through a base station. Occasionally, the data collection process is disrupted as a result of the energy level of the sensor network. The energy of sensor batteries can be drained by voids. Void sensors do not propagate messages intended for the destination. We have addressed the issue of voids in sensors with the Dynamic Void Removal Algorithm. Data stored in the cloud is being used and retrieved by multiple customers through specifying the relative record index of the sensor data collected. A security mechanism is built with the help of the relative record index associated with sensor data collection. Authenticated customers are given a secret key to rapidly retrieve data from the cloud. Meanwhile sensor networks require a secure mutual authentication scheme in an anxious network environment; we use the Relative Record Index method to design a new user authentication procedure. Our etiquette can handle all problems thrown up by the former schemes. Furthermore, it enhances Wireless Sensor Network authentication with a higher degree of security than other protocols. Therefore, our protocol is more suited to an open and higher-security Sensor Network environment despite greater computation cost and energy.

The effect of Lean on job satisfaction
by VARADARAJ ARAVAMUDHAN, ANANTH SENGODAN
Abstract: Lean principles and lean management are increasingly implemented in various sectors of organisations. Lean has shown visible effects in enhancing productivity, reducing wastage of time and materials while still maintaining customer satisfaction as well as employee satisfaction. Lean philosophy is about people understanding their motives and aspirations. Most of the literature works on lean say that the key driver for lean implementation is employee involvement and satisfaction with the process. Hence lean always focuses on employee motivation and their work performance. This thesis is proposed to study on the impact of lean on job satisfaction in organisations. The research data will be collected using the survey tool by distributing questionnaires to organisations that implement lean principles. The respondents who belong to the group that handles everyday work process and services will be selected to participate in the survey. The research survey data will be analysed using Microsoft Excel along with statistical tools like Correlation in order to have an in depth understanding on the findings of the research proposed through several hypothesis.
Keywords: enhancing productivity; reducing wastage of time; limitation of materials; employee motivation.

Studies on European Call Option of Binomial Option Pricing Model Using Taguchis L27 Orthogonal Array
by Amir Ahmad Dar, N. Anuradha
Abstract: There are several parameters affecting the European call option value such as strike price K, the price of an underlying asset S_0 , volatility σ, and time period t interest rate r. In this paper, the Binomial option pricing model is utilized to assess the estimations of European call option value. To explore the effects of input factors, Taguchi method of orthogonal L27 design experiment is carried out using an orthogonal array, Analysis of Variance (ANOVA), and Analysis of Mean (ANOM) were used. The purpose of this paper to find the best optimal combination by varying the parameters at constant interest rate r and the effects of parameters are discussed. The ANOM distinguishes which parameter influences higher on European call option value and furthermore, it demonstrates the best combination where the European call option will get the greatest value. The ANOVA estimates the percentage contribution of every parameter on European call option and the analysis is carried out using MINITAB software.
