  • Influence of chemical reaction, radiation and heat source on separation of
           binary fluid mixture with Soret and Dufour effects on MHD mixed convective
           flow past a vertical plate

    • Authors: Krishnandan Verma
      Abstract: The motive of the current study is to analyse the consequences of Soret, Dufour and thermal radiation on chemically reactive MHD mixed convective flow on separation of binary fluid mixture. Numerical techniques are applied to obtain the results by using Matlab solver bvp4c. Results are acquired for velocity, temperature and concentration distributions for various parameters and are portrayed graphically. The study discloses some interesting results where different parameters like Soret number, Dufour number, chemical reaction parameter helps in restricting the temperature near the plate and at the same time raising the lightweight ingredient's concentration close to the plate, ultimately assisting the separation process. Numerical data are computed for coefficient of skin-friction coefficient, Local Nusselt number as well as Sherwood number.

  • Some Operations on Complex Fuzzy Graphs

    • Authors: Azhagendran N, Mohamed Ismayil A
      Abstract: In this paper we discussed about some types of complex fuzzy
      graphs which is the extension of fuzzy graph. As the membership
      value of elements of fuzzy graph is in between 0 and 1. In complex
      fuzzy graph it will be extended to unit circle of complex plane. Some
      operations such as union, intersection, composition, cartesian product
      of two complex fuzzy graphs are introduced. Some basic theorems
      with respect to the above mentioned operations are proved with examples.

  • Degree of an edge and Platt Number in signed networks

    • Authors: Diviya K D, Anjaly Kishore
      Abstract: Positive labelled edges play a vital role in network analysis.The degree of edges in signed graphs is introduced by giving importance to
      positive edges incident on the end vertices of that edge. The concept
      of Platt number of a graph, which is the sum of degrees of its edges, is
      extended to signed graphs based on the degree defined. Bounds of degree of an edge and Platt number in certain classes of signed graphs
      are determined. Some characterizations on Platt number of signed
      graphs are also established. A model to analyse social networks using degree of edges and Platt number is also proposed.
      Keywords: Signed graph, positive edges, negative edges, networks,
      information diffusion, degree of an edge, Platt number

      Abstract: Given a fuzzy graph G = (V; ; ), the fz- domination number, fz(G),
      is the least scalar cardinality of an fz- dominating set of G. In this article,
      we examine several features of fz-domination number of fuzzy
      graphs as a result of various fuzzy graph operations. We find bounds
      for the fz-domination number of a few graph products and look at the
      requirements for the sharpness of these bounds.

  • Super Fuzzy Matrix of Inverse in kth Order

    • Authors: R. Deepa, Dr. P. Sundararajan
      Abstract: Unexpected event modelling is a affluent area of study in fuzzy matrix
      (FM) modelling. Every fuzzy matrix may be shown as a multidimensional
      cocept, but standard matrices cannot achieve this without
      the proper scale. To solve this issue, a certain kind of classical fuzzy
      matrix is required. In this study, the idea of an inverse of a k-regular
      fuzzy matrix is introduced, and some of its key characteristics are
      listed. As a result, the same regularity indicator is used to describe
      a matrix. Investigation is also done on the relationship between the
      regular, k-regular, and consistency of fuzzy matrices powers.

  • Stability of Domination in Graphs

    • Authors: Reeja Kuriakose, K. S Parvathy
      Abstract: The stability of dominating sets in Graphs is introduced and studied,
      in this paper. Here D is a dominating set of Graph G. In this
      paper the vertices of D and vertices of $V - D$ are called donors
      and acceptors respectively. For a vertex u in D, let $\psi_{D}(u)$ denote
      the number $\ N(u) \cap (V - D)\ . The donor instability or simply d-
      instability $d^{D}_{inst}(e)$  of an edge e connecting two donor vertices v and
      u is $\ \psi_{D}(u)-\psi_{D}(v)\ $. The d-instability of D, $\psi_{d}(D) is the sum of
      d-instabilities of all edges connecting vertices in D. For a vertex u
      not in D, let $\phi_{D}(u) denote the number $\ N(u)\cap D\ . The Acceptor Instability
      or simply a-instability  $a^{D}_{inst}(e)$  of an edge e connecting two
      acceptor vertices u and v is $\ \phi_{D}(u)-\phi_{D}(v)\ $. The a-instability of D,
      $\phi_{a}(D)$ is the sum of a-instabilities of all edges connecting vertices in
      $V - D$. The dominating set D is d-stable if $\psi_{d}(D) = 0$ and a-stable
      if $\phi_{a}(D) = 0$. D is stable, if $\psi_{d}(D) = 0$ and $\psi_{a}(D) = 0$. Given a
      non negative integer #\alpha$, D is $\alpha-d-stable$, if $d^{D}_{inst}(e)\leq\alpha$ for any edge
      e connecting two donor vertices and D is $\alpha-a-stable$, if $a^{D}_{inst}(e)\leq\alpha$
      for any edge e connecting two acceptor vertices. Here we study $\alpha$-
      stability number of graphs for non negative integer $\alpha$.

      Abstract: In this paper we introduce the superior eccentric domination polynomial $SED(G, φ) = β\sum_{ l=\gamma_{sed}(G)} sed(G, l) φ^{l}$ where sed(G, l) is the number of all distinct superior eccentric dominating sets with cardinality l and $\gamma_{sed}(G)$ is superior eccentric domination number. We find SED(G, φ) for different standard graphs. Results are presented.

  • Linear predictor and autocorrelation for noisy and delayed digital signal

    • Authors: G Vinu Priya, R Jothilakshmi
      Abstract: This paper deals with the association between the linear prediction and digital signal modeling and ends up with the suitable ways to predict the signal by considering a stationary signal $y_{n}$. The linear prediction of signal modeling based on the finite past and the solutions are arrived in a recursive manner. Further we analyzed the wiener filter along with spectral theorem and autocorrelation in terms ofpredictive analysis.This estimates the gap function along with delay and noise. The delayed signal’sproperties are analyzed like causal, stability and applied these into optimum filtering. Finally the predicted error is compared with linear predictor and Wiener filter. Then transfer function is applied to estimate the interval function and gap function along with delay.

  • Wheat Crop Yield Forecasting Using Various Regression Models

    • Authors: CV Shakila, SK Khadar Babu
      Abstract: The prediction of crop yield, particularly paddy production is a challenging task and researchers are familiar with forecasting the paddy yield using statistical methods, but they have struggled to do so with greater accuracy for a variety of factors. Therefore, machine learning methods such as Elastic Net, Ridge Regression, Lasso and Polynomial Regression are demonstrated to predict and forecast the wheat yield accurately for all India-level data. Assessment metrics such as coefficient of determination ($R^{2}$ ), Root Mean Square Error (RMSE), Mean Absolute Error (MAE), Mean Squared Error (MSE) and Mean Absolute Percentage Error (MAPE) are used to evaluate the performance of each developed model. Finally, while evaluating the prediction accuracy using evaluation metrics, the performance of the Polynomial Regression model is shown to be high when compared to other models that are already accessible from various research in the literature.

  • BIBO Stability and Decomposition Analysis of Signals and System with
           Convolution Techniques

    • Authors: C. B. Sumathi, R. Jothilakshmi
      Abstract: In this paper control system’s stability is arrived based on Bounded
      Input Bounded Output (BIBO) when bounded input is given in the
      form of discrete values. The control system allows the state estimation
      constraints to reach the convergence even when fluctuations in
      the parameters of the input system occur. To overcome this DTFT
      (Discrete Time Fourier Transform) is used when the signal is completely
      absolutely summable. Stability of the LTI (Linear time invariant)
      system is showed and is depending on the absolute summable of
      their impulse response. Simultaneously for continuous signal the stability
      occurs if it is absolutely integrable . LTI system is steady if their
      impulse responses encounter the Dirichlet conditions. In addition to
      that the linearity and time-invariance properties are discussed. This
      provide a new way to decompose the periodic signals into Fourier series
      by convolving the fundamental signals. Continuous and discrete
      time signals are focused in this paper to get linear time invariant system
      (LTI) through complex exponentials. Finally filtering techniques
      were used to eliminate the noisy frequency component in a signal.

  • Intuitionistic Robust Fuzzy Matrix for the Diagnosis of Stress, Anxiety
           and Hypertension

    • Authors: K. Revathi, Dr. P. Sundararajan
      Abstract: The mathematical model given here attempts to improve precision
      in the diagnosis of stress, anxiety, and hypertension using Intuitionistic
      robust fuzzy matrix (IRFM). In practice, the imprecise nature
      of medical documentation and the uncertainty of patient information
      frequently do not provide the appropriate level of confidence in the
      diagnosis. To that purpose, a novel method based on distinct fuzzy
      matrices and fuzzy relations is devised, which makes use of the capabilities
      of fuzzy logic in describing, understanding, and exploiting
      facts and information that are unclear and lack clarity. With the assistance
      of 30 doctors, a medical knowledge base is created during the
      procedure. The model obtained 95.55%t accuracy in the diagnosis,
      demonstrating its utility.

  • Solving fuzzy linear programming problems by using the fuzzy exponential
           barrier method

    • Authors: A Nagoor gani, R Yogarani
      Abstract: In order to resolve the fuzzy linear programming problem, the fuzzy exponential barrier approach is the major strategy employed in this article. To overcome the problems with fuzzy linear programming, this method uses an algorithm. In this concept, a fuzzy inequality constraint is produced since the objective functions are convex.numerical examples are provided.

  • Robust Fuzzy Graph

    • Authors: A. Sudha, Dr. P. Sundararajan
      Abstract: The idea of fuzzy graphs is crucial for dealing with uncertainty in
      day-to-day living situations. In this work, we have a present a work
      fuzzy graph associates with robustness model that’s easy, flexible, and
      simple. With this model, we have a tendency to address the examination
      planning downside below uncertainty supported. Randomness
      and unclearness are two very separate types of uncertainty in knowledge.
      This study bridges resilient fuzzy graphs and addresses every
      type of uncertainty in higher cognitive processes. In this paper we introduce
      a type of fuzzy graph relating with robustness is called robust
      fuzzy graph and some of its properties. Robust fuzzy graph becomes
      a best tool in evidence theory for calculating belief functions, plausibility
      functions, spanning functions etc.
