  • Incorporating carbon emissions in queuing models to determine lot sizes and inventory buffers in a supply chain   Order a copy of this article
    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   Order a copy of this article
    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   Order a copy of this article
    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   Order a copy of this article
    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.

  • Innovativeness, Environment and Performance of Small and Medium-sized Enterprises (SMEs) in the Manufacturing Sector in Malaysia   Order a copy of this article
    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.

    by Sukhraj Takhar, Kapila Liyanage 
    Abstract: The traditional linear economic system focuses on the mass production of products, using available resources, at the lowest possible cost. Sustainability recognizes the impact of dwindling natural resources, as a result of mass production and directs us towards the use of more sustainable resources. The Circular Economy (CE) proposes the adoption of an open loop manufacturing system where products are designed using resources which enable products to be repaired, reused, repurposed and recycled. To analyse the impacts of sustainability and CE initiatives, accurate data needs to be collected. Industry 4.0 promotes interconnectivity, enabling real-time data collection, communication and data analytics. This paper contributes to existing literature by identifying a research gap on how sustainability and CE model data reporting needs may be met using Industry 4.0 technologies. Using a literature review and survey on real-world adoption, a set of reporting requirements for sustainability and CE models are identified- The conclusions provide an assessment of how Industry 4.0 may aid reporting needs.

  • Supply network configuration archetypes for the circular exploitation of solid waste   Order a copy of this article
    by Naoum Tsolakis, Dimitris Zissis, Jagjit Singh Srai 
    Abstract: This research aims to use network configuration theory to propose circular supply chain archetypes for the valorisation of solid waste. The proposed network configuration archetypes are differentiated by their levels of geographic dispersion, each representing coherent clusters of waste material and supply network characteristics for the valorisation of waste streams, namely: centralised, semi-centralised and decentralised. The different types of solid waste require local (e.g. wood, organic waste), regional (e.g. glass, plastics and rubber, paper and cardboard) or pan-regional (e.g. metals and alloys) network configuration options primarily dictated by the intrinsic physico-chemical properties of the wasted material and constraints related to the processing technologies. Furthermore, the proposed network configuration archetypes dictate operational considerations, such as procurement and pre-processing options for the wasted feedstocks, along with upscale production opportunities and distribution of the value-added intermediates or end-products.
    Keywords: circular supply networks; supply chain configuration archetypes; solid waste; renewable feedstocks; commercial value and viability.

    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   Order a copy of this article
    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.

  • A Hybrid Medical Image Coding Based on Block Truncation Coding and Residual Vector Quantization   Order a copy of this article
    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   Order a copy of this article
    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   Order a copy of this article
    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.

  • Changed Detection of Landsat 8 Imagery using Object Based Image Analysis with Particle Swarm Optimization   Order a copy of this article
    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.

  • High Performance Inventive System for Gait Automation and Detection of Physically Disabled Persons   Order a copy of this article
    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.

    by Nimitha Aboobaker, Zakkariya K.A., Manoj Edward 
    Abstract: Organizational performance and sustainability in the contemporary technological world is largely driven by the relentless change and continuous innovations brought about by employees. In this context, this paper investigates the relationship between workplace spirituality and innovative work behavior, based on an empirical research conducted among 208 employees working in information technology sector. The study also examined the mediating role of individual readiness for change in the aforementioned relationship. The three dimensions of workplace spirituality had varying influences on outcome variables. Employees with higher experiences of meaningful work and alignment with organizational values had higher readiness for change and innovative work behaviour. Findings of this study revealed no significant direct effect of sense of community on innovative work behaviour of the employees. Nevertheless, sense of community had an indirect effect on innovative work behaviour, through the mediating role of readiness to change. Implications for employees experience of workplace spirituality and outcomes, so as to meet the challenges of a VUCA (volatile, uncertain, complex and ambiguous) business environment are elaborated.

  • Impact of Organizational Justice on Perception of Ability-Job-Fit in Changing Environment   Order a copy of this article
    by MRINALI Tikare 
    Abstract: Abstract Purpose The study aims to investigate the association/relationship among Procedural Justice, Distributive Justice and Perceived-Ability-Job-Fit. Design/Methodology/Approach 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. Findings 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. Practical Implications The findings will be useful for employees to reduce stress by understanding the Fit Concepts.

  • Price Discovery and Volatility Transmission in the Spot and Futures Market of Pepper: An Empirical Analysis   Order a copy of this article
    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.

    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.

    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.

    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.

    Abstract: Bioinformatics is an active research area which combines biological matter as well as computer science research. The longest common subsequence (LCS) is one of the indispensable issue to be unraveled viably in computational science. Discovering LCS is fundamental undertaking in Deoxyribonucleic Acid (DNA) arrangement investigation and other molecular biology. In this paper, new calculation for discovering LCS of two DNA successions and its area is proposed. The objective of this created framework is to discover the area and length of all subsequences which introduces in the two arrangements. To achieve this, DNA sequences are stored in an array and the comparison of DNA sequences are performed using matching algorithm. At the end of matching process, group of subsequence are obtained. Then the length and location of the matched subsequence are computed. After completing the matching process, longest common subsequence(s) is located. In this proposed work, maximally obtained length of LCS is 8. Finally, the computation time is calculated for locating LCS in DNA sequences. In addition to this, computation time is analyzed by gradually increasing the length (in characters count) of DNA sequences from 100, 200, 300, 400 and 500. It concludes that computation time for locating LCS in various lengths of DNA sequences took few seconds difference only.

    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.

    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   Order a copy of this article
    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.

    Abstract: Word sense disambiguation is the way to compute the correct sense of a word. It is considered as one of the important subtasks in natural language processing, machine translation and information retrieval. WSD found improving the overall performances of these systems. The job of WSD is to eliminate all senses of a word except the appropriate one as per the given context. The work in Tamil linguistics domain for information retrieval or natural language processing is very less. WSD can be performed in supervised and unsupervised manner. Here, we have proposed an unsupervised approach to disambiguate Tamil words in a given context using the context words and their dictionary gloss definitions. We have proposed two variants of our approach. The first approach uses the number of word overlapping between the glosses of context words whereas the second one uses the similarity between the glosses of context words with that of the ambiguous word. The second one found best among the two. For our approach, we have used Tamil Indo Wordnet, Oxford Tamil dictionary and English WordNet dictionary glosses. Our method achieves better result in recognizing correct senses in Tamil text.

  • Rapid Retrieval of Secured Data from the Sensor Cloud using a Relative Record Index and Energy Management of Sensors   Order a copy of this article
    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.

  • Comparative Study on IDS using Machine learning approaches for Software Defined Networks   Order a copy of this article
    by Muthamil Sudar K, Deepalakshmi P 
    Abstract: Software defined 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 centralised 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. Nowadays, 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.

  • Reinforcement based Heterogeneous Ensemble for Anomaly Detection in Streaming Environment   Order a copy of this article
    by Sanjith S L, E. George Dharma Prakash Raj 
    Abstract: Intrusion detection in networks is a challenging process, mainly due to huge amount of data and the imbalanced nature of the data. Further, the ever-changing transmission patterns introduce concept drift, which also exhibits a huge challenge. This work presents a heterogeneous ensemble based prediction model to detect anomalies in the network environment. The major goal of the proposed model is to provide faster, more efficient real-time predictions and to enhance the reliability of the model by providing an iterative mechanism to handle concept drifts. The ensemble is created using three varied base learners and the results are aggregated using a voting combiner to provide results. Decision tree, random forest, and gradient boosting trees are used as the base learners. The varied nature of the learners enables effective performances in models. Further reinforcement and an iterative training component is introduced into the model to handle concept drift. Experiments were performed on benchmark intrusion detection data and the results indicate the high performing nature of the model. Comparisons were performed with recent state-of-the-art models in literature and they indicate improved performances of the proposed model, indicating the high performing nature of the proposed ensemble model.

    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 neighbour 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.

  • Factors influencing Information and Communication Technology diffusion in Nigerias transport and logistics industry:an exploratory study .   Order a copy of this article
    by Anthony Ezenwa, Anthony Whiteing, Daniel Johnson, Akunna Oledinma 
    Abstract: Modern transport and logistics management is replete with the applications of advancements of Information and Communication Technology (ICT). However, the barriers to ICT innovation diffusion in the industry are widely acknowledged, particularly in the context of developing countries. Although ICT innovation diffusion reflects a continuum of conditional forces that coalesce around institutional forces; how different locally-evolved factors are influencing ICT diffusion in the developing logistics markets remains an under-researched issue. Moreover, ICT innovation acceptability and operative constraints of various stakeholders in the industry also remains a subject of concern. This paper combines primary qualitative studies (focus group discussion and in-depth expert interviews) to explore (i) how institutional forces in Nigeria are influencing ICT diffusion in the transport and logistics industry, using evidence from the local 3PL SMEs, (ii) the perceptions of the relevant stakeholders concerning ICT diffusion challenges in the industry and their roles in modulating them. The systematic analyses of the qualitative data, including content, thematic, magnitude coding, and interpretative procedures provide a useful way of understanding the mechanisms influencing ICT diffusion in Nigeria's transport and logistics industry and where discourses differ. In exploring the views of the stakeholders, one can observe that institutional forces are more oriented towards complexity than predictability, doing little to address either the structural challenges of the industry or the operational threats of the local logistics operators. The study concludes by illustrating that a turn towards institutional voids thinking will help advance sustainable ways to mitigate ICT diffusion challenges in the Nigerian transport and logistics industry.

  • Drivers and barriers of consumer purchase intention of remanufactured mobile phones: a study on Indonesian consumers   Order a copy of this article
    by Didik Wahjudi, Shu San Gan, Yopi Yusuf Tanoto, Jerry Winata 
    Abstract: Remanufacturing is widely practiced because it reduces landfill, saves energy, and conserves natural resources. Little effort is given to exploring the acceptance of remanufactured products, especially the short life-cycle ones. Indonesia, the fourth largest mobile phone users, need to tackle the vast WEEE deriving from obsolete mobile phones. This study investigates drivers and barriers of consumer purchase intention for remanufactured mobile phones. Thirteen respondents were interviewed, representing different age groups, genders, and social classes. The key drivers are the affordable price, upgraded specification, and product warranty, while the regulatory concern, trend concern, and obsolescence concern are the main barriers. Perceived quality and quality assurance can be both drivers and barriers, depending on the level. This study recommends remanufacturers to focus on providing upgraded specification at an affordable price and providing information about the remanufacturing process. This study also argues the urgency for the government to enforce rigorous regulation against counterfeit products.

  • Assessing Significant Factors for Sustainable Cold Chain Performance in Sri Lankan Context   Order a copy of this article
    by Keshala Wickrama Gunaratne, Pradeepa Jayaratne 
    Abstract: Purpose - Nearly one third of the food that is globally produced is wasted mostly during initial production and in transit or thrown away by wealthier economies due to unsuitability for consumption. The main ways of food spoilage occur during storage, transportation and production activities. While cold chains are becoming an imperative fragment in most of the developed countries at present, when it comes to developing countries like Sri Lanka there is huge loss incurred annually due to poor practices in this sector. Considering the importance of supply chain in the field of perishable commodities, the main objective of this study is to identify the contributing factors with a specific goal of reducing waste and facilitating sustainable performance in the cold supply chain. Design/Methodology/Approach The evolution of the research field is analyzed with the use of extensive literature survey in five different industries that use cold chain practices in Sri Lanka. Study was carried out mainly in three stages. To identify the most significant factors, Exploratory Factor Analysis (EFA) was used followed by Confirmatory Factor Analysis (CFA). Finally, for the derivation of factor-based relationship model Structural Equation Modelling was used (SEM). Furthermore, the evolution of performance and sustainable measurement in cold chain were used to highlight the criticalities of the research field. Findings The authors classify three main significant factors that impact sustainability in perishable supply chain. The paper highlights the inadequacies in the available literature to achieve food quality and nutrition with less wastage and what main areas that need focus to achieve sustainability goals. Moreover, these key areas are open for scholars to plan future research in this area. Research limitations/implications The results presented from this paper is limited to large & medium scale entities that use cold chain practices anywhere along the supply chain. Also due to restrictions of information sharing from certain companies the sample size has a moderate number, with an above par response rate of 63%. The results of this study can be used by researchers to focus on specific industries at large scale to have more implications on sustainability. In addition, practitioners can develop a performance measurement framework including the main three factors that authors propose to achieve their sustainable goals within their food supply chain. Originality/Value Research on perishable supply chain is receiving immense attention from both academia and practitioners due to significant relevance towards sustainability and food quality. The body of knowledge is yet immature and this paper provides a new perspective of thinking towards attaining sustainability performance. The work is original in the way authors integrate sustainability across the three key factors that identified across supply chain in every strategic, operational and tactical decisions. The context can be used by researchers and practitioners to develop practical sustainable cold chain performance framework.
