Modeling and Simulation of Fiber Bragg Grating (Fbg) as A Strain Sensor

Muhammad Arif Bin Jalil

[ View:    Abstract ] [ PDF ] [ XML ]

This study presents the modelling, simulation, and characterization of the Fiber Bragg grating (FBG) on maximum reflectivity, bandwidth, the effect of applied strain to the wavelength shift, ʎB and sensitivity of the wavelength shift with strain for optical sensing system. In this study, a commercial FBG with the center wavelength of 1550nm is used in order to measure the spectral response of FBG to strain. The parameters used in these simulations are the fiber grating length, L ranging from 1 to 10mm, the changes in refractive index, ∆n from 0.0002 to 0.0020, the effective refractive index, is 1.46 and the grating period of FBG,Λ for 530nm in the performance of FBG. The bandwidth and spectrum reflectivity are analyzed from the variation of refractive index and grating length. Simulations on the FBG are carried out using OriginPro 2016 and Microsoft Excel 2010 software. The Excel sheet is used to generate data and the OriginPro 2016 is used to generate the graphs. The results obtained indicates the variation in grating length and refractive index affect the spectral reflectivity and the bandwidth. In addition, results obtained show that the changes in the Bragg wavelength are due to an increase in length of the grating region which due to the applied strain.

[ View:    Abstract ] [ PDF ] [ XML ]

The industry developed dramatically in the second half of the 20th century, And with it developed and manufacturing systems ranging from manual to fully computerized systems employing information and communication technology (ICT). This fact has made the manufacturing systems to be totally dependent on ICT and therefore these systems have to keep pace with the advancement in ICT. Distributed computing has totally changed the computing paradigm in recent times resulting in rapid employment of these technologies in the manufacturing sector. An important variable in the equation determining the trend of manufacturing technologies is the purchaser choice and preference which has become active recently. To address these heterogeneous user demands, the Autonomous Decentralized System (ADS) concept was introduced five decades ago. The ADS has been a significant development incorporated in modern manufacturing systems and have been standardised as the de-facto standard for factory automation. These systems hold the assure for on-line system maintenance, timeliness and assurance, ensuring greater productivity and cost benefit emerging as the system of choice in automated manufacturing systems. This paper reviews the ADS, its application to a manufacturing system, assesses the state of the art and discusses the future trends.

Approximation Query Layer (AQLayer): Design and Architecture

Tamanna Siddiqui and Mohammad AlKadri

[ View:    Abstract ] [ PDF ] [ XML ]

Data Scientists need to manipulate with data (retrieve, aggregate, join, …. ) - when they do their tasks - for that it will be very useful to build a layer which prepare the data to be convenient for analysing step; with an approximation processing and some error tolerant defined by the user, that layer will handle both inserting records or collections to the database and retrieving the information from that database.

In this paper we will focus on the structure and the design of this layer, and dig deeper how this layer will translate the user’s inquiring manner to a SQL statement suitable for approximation processing.

Cellular Automata Based Study of Spectral Signatures of Dal_Lake Infrared Imagery

Fasel Qadir

[ View:    Abstract ] [ PDF ] [ XML ]

Among all the water bodies in Jammu & Kashmir Dal Lake has a peculiar significance due to its location in the heart of the capital city Srinagar. Historical studies over last fifteen hundred years indicate a continuous squeezing of the Lake due to different natural and manmade interventions. Over this long period, the governance of the land has passed through various wise and ugly human plans besides some slow natural processes. The mathematical modelling of such a dynamics is not an easy task because of the many intervening variables and the difficulty which implies their measurements. On the other hand, during the last decades, the use of Cellular Automata (CA) techniques to simulate the behaviour of linear or non-linear systems is becoming of great interest. This fact is mainly due to the fact that this approach depends largely on local relations and a series of rules instead of precise mathematical formulae. The infrared (IR) satellite imagery can be helpful in identifying the different areas of interest using CA as a tool of image processing. The study will not only separate the areas of interest but also pave a way towards a comprehensive study of all the identified zones using spectral signatures received from the continuous IR imagery of both pre-monsoon and post-monsoon periods in future.

Enhancing the Classification Accuracy of Noisy Dataset By Fusing Correlation Based Feature Selection with K-Nearest Neighbour

Samir Kumar Singha and Syed Imtiyaz Hassan*

[ View:    Abstract ] [ PDF ] [ XML ]

The performance of data mining and machine learning tasks can be significantly degraded due to the presence of noisy, irrelevant and high dimensional data containing large number of features. A large amount of real world data consist of noise or missing values. While collecting data, there may be  many irrelevant features that  are collected by the storage repositories. These redundant and irrelevant feature values distorts the classification principle  and  simultaneously increases calculations overhead and decreases the prediction ability of the classifier. The high-dimensionality of such datasets possesses major bottleneck  in the field of data mining, statistics, machine learning. Among several methods of dimensionality reduction,  attribute or feature selection technique is often used in dimensionality reduction. Since the k-NN algorithm is sensitive to irrelevant attributes therefore its performance degrades significantly when a dataset contains missing values or noisy data. However, this weakness of the k-NN algorithm can be minimized when combined with the other feature selection techniques. In this research we combine the Correlation based Feature Selection (CFS) with k-Nearest Neighbour (k-NN) Classification algorithm to find better result in classification when the dataset contains missing values or noisy data.  The reduced attribute set decreases the time required for classification. The research shows that when dimensionality reduction is done using CFS and classified with k-NN algorithm, dataset with nil or very less noise may have negative impact in the classification accuracy, when compared with classification accuracy of k-NN algorithm alone. When additional noise is introduced to these datasets, the performance of k-NN degrades significantly. When these noisy datasets are classified using CFS and k-NN together, the percentage in  classification accuracy is improved.

Detection and Isolation of Zombie Attack under Cloud Environment

Sunil Kumar and Maninder Singh

[ View:    Abstract ] [ PDF ] [ XML ]

Network security, data security and several other security types such as the computer security collectively compose the word “Cloud Security”. Cloud computing posses a new challenge because traditional security mechanism is being followed are insufficient to safeguard the cloud resources. Cloud computing can easily be targeted by the attackers. A group of malicious users or illegitimate users can attack on system which may lead to denial the services of legitimate users. Such kinds of attacks are performed by the malicious (zombie) attackers. The zombie attack will degrade the network performance to large extend. Traditional techniques are not easily capable to detect the zombie attacker in the cloud network. So in this paper we have proposed a technique which is the enhancement of the mutual authentication scheme in order to detect and isolate zombie attack for the efficient performance of the network.

An Optimal Resource Provisioning Algorithm for Cloud Computing Environment

Shivangi Nigam and Abhishek Bajpai

[ View:    Abstract ] [ PDF ] [ XML ]

Resource Provisioning in a Cloud Computing Environment ensures flexible and dynamic access of the cloud resources to the end users. The Multi-Objective Decision Making approach considers assigning priorities to the decision alternatives in the environment. Each alternative represents a cloud resource defined in terms of various characteristics termed as decision criteria. The provisioning objectives refer to the heterogeneous requirements of the cloud users. This research study proposes a Resource Interest Score Evaluation Optimal Resource Provisioning (RISE-ORP) algorithm which uses Analytical Hierarchy Process (AHP) and Ant Colony Optimization (ACO) as a unified MOMD approach to design an optimal resource provisioning system. It uses AHP as a method to rank the cloud resources for provisioning. The ACO is used to examine the cloud resources for which resource traits best satisfy the provisioning. The performance of this approach is analyzed using CloudSim. The experimental results show that our approach offers improvement in the performance of previously used AHP approach for resource provisioning.

C.P. Patidar1 and Arun Dev Dongre2

[ View:    Abstract ] [ PDF ] [ XML ]

Today we live in the era of software and web applications. Software is used in every minor and major field. In defense, medical, education, research, government, administration and much other field software became a necessary part. Software also brings transparency in the systems. Software also makes people’s life easy and comfortable. Software testing is a very important part of any software development process. Software testing requires approximately forty percent budget of any software development process. Like in an automobile industry every vehicle is tested before it goes to the customer. Also in software testing it is must to test the software before deployment. Because if software deployed without testing then user will face the bug and user will be unhappy with the software. In this paper we compare manual and automated testing and proposed an automated testing model with test driven development (TDD).

Breast Cancer Detection using Image Processing Techniques

Prannoy Giri and K. Saravanakumar 

[ View:    Abstract ] [ PDF ] [ XML ]

Breast Cancer is one of the significant reasons for death among ladies. Many research has been done on the diagnosis and detection of breast cancer using various image processing and classification techniques. Nonetheless, the disease remains as one of the deadliest disease. Having conceive one out of six women in her lifetime. Since the cause of breast cancer stays obscure, prevention becomes impossible. Thus, early detection of tumour in breast is the only way to cure breast cancer. Using CAD (Computer Aided Diagnosis) on mammographic image is the most efficient and easiest way to diagnosis for breast cancer. Accurate discovery can effectively reduce the mortality rate brought about by using mamma cancer. Masses and microcalcifications clusters are an important early symptoms of possible breast cancers. They can help predict breast cancer at it’s infant state.  The image for this work is being used from the DDSM Database (Digital Database for Screening Mammography) which contains approximately 3000 cases and is being used worldwide for cancer research. This paper quantitatively depicts the analysis methods used for texture features for detection of cancer. These texture featuresare extracted from the ROI of the mammogram to characterize the microcalcifications into harmless, ordinary  or threatening. These features are further decreased using Principle Component Analysis(PCA) for better identification of Masses. These features are further compared and passed through Back Propagation algorithm (Neural Network) for better understanding of the cancer pattern in the mammography image.

Malware is a malicious instructions which may harm to the unauthorized private access through internet. The types of malware are incresing day to day life, it is a challenging task for the antivius vendors to predict and caught on access time. This paper aims to design an automated analysis system for malware classes based on the features extracted by Discrete Wavelet Transformation (DWT) and then by applying four level  decomposition of malware. The proposed system works in three stages, pre-processing, feature extraction and classification. In preprocessing, input image is normalized in to 256x256 by applying wavelet we are denoising the image which helps to enhance the image. In feature extraction, DWT is used to decompose image into four level. For classification the support vector machine (SVM) classifiers are used to discriminate the malware classes with statistical features extracted from level 4 decomposition of DWT such as Daubechies (db4), Coiflet (coif5) and Bi-orthogonal (bior 2.8). Among these wavelet features the db4 features effectively classify the malware class type with high accuracy 91.05% and 92.53% respectively on both dataset. The analysis of proposed method conducted on two dataset and the results are promising.

Major challenges of Mobile Adhoc Networks

Dharmesh Bhatt* and Bijendra Agrawal

[ View:    Abstract ] [ PDF ] [ XML ]

In the unknown environment of network the security the major issue for safe communication between the nodes. In such networks a lot of active and passive attacks are done by the attackers in groups in the data packets and routing messages. Mobile Adhoc networks are such type of networks which does not have any centralized authentication and the nodes communicate with each other. In MANET security plays a vital role for safe communication. The focus is given on security of Mobile Adhoc Networks. MANET is open network which is available for the malicious and trustworthy users to communicate. The MANET has to design a robust solution which deals with such type of malicious attackers so that a health network transmission takes place between trustworthy nodes. The Mobile Adhoc Networks are the network which works in isolation along with the wired infrastructure. This elasticity of MANET is its biggest strength but it is also a big vulnerability for security issues. In paper we will discuss the active and passive attacks including black hole attacks, spoofing, warm hole, flooding and traffic monitoring, traffic analysis and eavesdropping respectively.

Neha Bhatia1, Himani2 and Chander Kant3

[ View:    Abstract ] [ PDF ] [ XML ]

Biometric authentication using fingerprint is one of the unique and reliable method of verification processes. Biometric System suffers a significant loss of performance when the sensor is changed during enrollment and authentication process. In this paper fingerprint sensor interoperability problem is addressed using Gabor filter and classifying images into good and poor quality. Gabor filters play an important role in many application areas for the enhancement of various types of fingerprint images. Gabor filters can remove noise, preserve the real ridges and valley structures, and it is used for fingerprint image enhancement. Experimental results on the FVC2004 databases show improvements of this approach.

Ankush Saklecha and Jagdish Raikwal

[ View:    Abstract ] [ PDF ] [ XML ]

Clustering is well-known unsupervised learning method. In clustering a set of essentials is separated into uniform groups.K-means is one of the most popular partition based clustering algorithms in the area of research. But in the original K-means the quality of the resulting clusters mostly depends on the selection of initial centroids, so number of iterations is increase and take more time because of that it is computationally expensive. There are so many methods have been proposed for improving accuracy, performance and efficiency of the k-means clustering algorithm. This paper proposed enhanced K-Means Clustering approach in addition to Collaborative filtering approach to recommend quality content to its users. This research would help those users who have to scroll through pages of results to find important content.

Research Summary of A Study for the Estimation of Legacy Programs for Effective Re engineering

Harmeet Kaur1, Shahanawaj Ahamad2 and  Govinder N. Verma3

[ View:    Abstract ] [ PDF ] [ XML ]

The present research estimates the efficacy of a legacy program and the areas of its development. The research also intends to put forward as to what extent reengineering of a legacy program has to be done on the basis of the estimation approach. The study has tried to outline the current issues and trends in reengineering of a legacy program from various perspectives. An all-inclusive literature review reveals that a lot of work has already been piled up with legacy system estimation and the reengineering domain, yet the basic assumptions of Complexity, Quality and Effort have not been worked out collectively. Hence the present research underlines this very maxim and studies the reengineering of a legacy program on the paradigms of Quality, Complexity, and Effort Estimation collectively. The findings put forward an equation and reengineering scale which would be highly compatible with present technology for the feasibility of an effective reengineering.

Survey on Packet Marking Algorithms for IP Traceback

Y. Bhavani1*, V. Janaki2 and R. Sridevi3

[ View:    Abstract ] [ PDF ] [ XML ]

Distributed Denial of Service (DDoS) attack is an unavoidable attack. Among various attacks on the network, DDoS attacks are difficult to detect because of IP spoofing. The IP traceback is the only technique to identify DDoS attacks. The path affected by DDoS attack is identified by IP traceback approaches like Probabilistic Packet marking algorithm (PPM) and Deterministic Packet Marking algorithm (DPM). The PPM approach finds the complete attack path from victim to the source where as DPM finds only the source of the attacker. Using DPM algorithm finding the source of the attacker is difficult, if the router get compromised. Using PPM algorithm we construct the complete attack path, so the compromised router can be identified. In this paper, we review PPM and DPM techniques and compare the strengths and weaknesses of each proposal.

K. Sharmila1,*, V. Janakiand A. Nagaraju3

[ View:    Abstract ] [ PDF ] [ XML ]

Confidentiality and Authentication were once treated different but now-a-days, improvement in technology is demanding both of them to be used together. Though technology is increasing tremendously, smart hackers on the environment always challenges the authentication factors, thereby enforcing more number of factors for authentication to be included. As factors increase, failure rate for authentication may also be more when any one of the factors doesn’t work.  A qualitative survey of user authentication systems being used in today’s environment is presented here and a comparative study of various authentication mechanisms used in the world of Information security by various researchers is shown.

Cardiovascular Disease Prediction Using Data Mining Techniques: A Review

Mudasir M Kirmani

[ View:    Abstract ] [ PDF ] [ XML ]

Cardiovascular disease represents various diseases associated with heart, lymphatic system and circulatory system of human body. World Health Organisation (WHO) has reported that cardiovascular diseases have high mortality rate and high risk to cause various disabilities. Most prevalent causes for cardiovascular diseases are behavioural and food habits like tobacco intake, unhealthy diet and obesity, physical inactivity, ageing and addiction to drugs and alcohol are to name few. Factors such as hypertension, diabetes, hyperlipidemia, Stress and other ailments are at high risk to cardiovascular diseases. There have been different techniques to predict the prevalence of cardiovascular diseases in general and heart disease in particular from time to time by implementing variety of algorithms. Detection and management of cardiovascular diseases can be achieved by using computer based predictive tool in data mining. By implementing data mining based techniques there is scope for better and reliable prediction and diagnosis of heart diseases. In this study we studied various available techniques like decision Tree and its variants, Naive Bayes, Neural Networks, Support Vector Machine, Fuzzy Rules, Genetic Algorithms, and Ant Colony Optimization to name few. The observations illustrated that it is difficult to name a single machine learning algorithm for the diagnosis and prognosis of CVD. The study further contemplates on the behaviour, selection and number of factors required for efficient prediction.
