Authors : J.Arockia Aruldoss and S.Pushparaj

Abstract: A graph G with p vertices and q edges is a mean graph if there is an injective function f from the vertices of G to $\{0,1,2,\dots,q\}$ such that when each edge uv is labeled with $\frac{(f(u)+f(v))}{2}$ if $(f(u)+f(v))$ is even and $\frac{(f(u)+f(v)+1)}{2}$ if $(f(u)+f(v))$ is odd then the resulting edges are distinct. A fan graph Fm,n is defined as the graph join $\bar{K}_m+P_n$ where $\bar{K}_m$ is the empty graph on m nodes and $P_n$ is the path graph on n nodes. The case $m=1$ corresponds to the usual fan graphs. In this paper we investigate vertex odd and even mean labeling of Fan graph, Mongolian tent and $\bar{K}_2+\mathcal{C}_n$.

Title : A Decagonal Fuzzy Number and its Vertex Method
Country : India
Authors : J.Jon Arockiaraj and N.Sivasankari

Abstract: The decision data of human judgements with preferences are often vague so that the usual ways of using crisp values are in adequate in many real life situation. Also using fuzzy numbers such as triangular, trapezoidal are not suitable in few cases where the uncertainties arises in ten different points. Therefore, Decagonal Fuzzy Number (DFN) and its arithmetic operations based on $\alpha$-cut are introduced. Also, the linguistic terms can be expressed in Decagonal fuzzy numbers and a vertex method is defined to calculate the distance between two Decagonal fuzzy numbers.

Keywords: Fuzzy Arithmetic, Linguistic values, Decagonal Fuzzy Number (DFN), $\alpha$ cut.

Title : Sentiment Analysis for Online Product Reviews using NLP Techniques and Statistical Methods
Country : India
Authors : S.Muthukumaran, P.Suresh and A.Victoria Anand Mary

Abstract: Opinion mining or sentiment analysis is the computational study of opinions or emotions towards aspects or things. The aspects are nothing but attributes or components of the individuals, events, topics, products and organizations. Opinion mining has been an active research area in Web mining and Natural Language Processing (NLP) in recent years. Online reviews are now popularly used for judging quality of product or service and influence decision making of users while selecting a product or service. Due to innumerous number of customer reviews on the web, it is difficult to summarize them which require a faster opinion mining system to classify the reviews. Reviews is proposed as there are many user generated product reviews available online many researchers have explored various supervised and unsupervised machine learning techniques for binary classification of reviews. In this paper, we can show that the statistical methods are often combined with traditional linguistic rules and representations. In view of these facts, we argue that the Naive Bayes classification model and Hidden Markov Models is applied to analyze the polarity of the sentiment on online product reviews due to its computational simplicity and stochastic robustness.

Keywords: Sentiment analysis (SA), Opinion mining, Machine learning, Naive Bayes (NB), Support Vector Machine (SVM), online reviews, Hidden Markov (HMM).

Country : India
Authors : W.Stanly and R.Vasanthakumari

Abstract: The Combined effect of Solute gradient and Magnetic field on Dusty Couple stress fluid through Porous medium is considered. The analysis is carried out within the framework of linear stability theory and normal mode technique. For the case of stationary convection, solute gradient has stabilizing effect whereas Dust particles are found to have a destabilizing effect on the system. Couple – Stress and Medium permeability have dual character to its stabilizing effect in the absence of magnetic field and rotation. Magnetic field has succeed in stabilizing effect in the absence of rotation. The oscillatory modes are introduced due to the presence of magnetic field in the system. Graphs have been plotted by giving numerical values to the parameters to depict the stability characteristics.

Title : A Batch Arrival Two Types of Bulk Service Queue with Server Breakdown and Modified M-Vacation
Country : India
Authors : G.Ayyappan, R.Vimala Devi and S.Suganya

Abstract: In this paper a batch arrival two types of general bulk service queuing system with server breakdown and modified M-vacation is considered. The service is done in bulk with a minimum of `$a$' customer and a maximum of `$b$' customers. At first the server provides first essential service (FES) bulk service) to the arriving customers and sequentially the server must provide second essential services (SES). At the completion of two types of service, if the server is breakdown with probability $\pi$, then the renovation of service station will be consider. After completing the renovation of service station or there is no breakdown of the service with probability $(1-\pi)$, the queue length is less than `$a$' then the server will avail of multiple vacations till the queue length reaches $`a'$ or consequently he completes M number of vacations, which occurs first, After completing the M-th vacation, if the queue length is still less than a then the server remains in the system till it reaches a (this period is known as dormant period). At a vacation completion epoch or a two type of services completion epoch or during the dormant period, if the queue length $\xi$ is at least a, the server service a batch of minimum $(\xi, b)$ customers where $b\ge a$. The probability generating function of queue science at the random epoch is obtained.

Title : A Batch Arrival Two Types of Bulk Service Queue with Vacation Interrupted, Optional Service and Closedown
Country : India
Authors : G.Ayyappan, S.Suganya and R.Vimala Devi

Abstract: In this paper a batch arrival two types of general bulk service queuing system with vacation interrupted, optional service and closedown is considered. The service is done in bulk with a minimum of `$a$' customer and a maximum of `$b$' customers. At first the server provides first essential service (FES) (bulk service) to the arriving customers and sequentially the server must provide second essential services (SES). At the completion of two types of service the leaving batch of customers may request for optional service with probability $\pi$. If no request for optional service is made after the completion of two type of service or after completion of optional service and number of customers in the queue is less than `$a$' then the server closed down its work. After that the server goes for single vacation. If the queue size reaches `$a$' during the vacation, the server terminates the vacation abruptly and resumes for FES. On completion of the vacation the server remains in the system (dormant period) until the queue length reaches `$a$'. After the completion of optional service with $\pi$ or after completion of two type of service with $(1-\pi)$ and the number of customer in the queue is greater than `$a$' the server will continue the batch service with general bulk service rule. The probability generating function of queue science at the random epoch is obtained.
