17. Approximation by modified Bernstein polynomials based on real parameters.

Author

Rajawat, Ruchi Singh, Singh, Karunesh Kumar, and Mishra, Vishnu Narayan

Subjects
LIPSCHITZ spaces, BERNSTEIN polynomials, ERROR functions, GENERALIZATION
Abstract

In this paper, we introduce a modified Bernstein-type operators based on two real parameters and study its various approximation properties. We derive some direct results e.g. Voronovkaja type asymptotic theorem, an estimate of error in ordinary as well as in Ditzian Totik modulus of smoothness and an error estimate for functions belonging to the Lipschitz type space. Further, we examine the rate of approximation for a Kirov and Popova type generalization of these operators. [ABSTRACT FROM AUTHOR]

Abstract

The goal of this manuscript is to introduce a new sequence of generalized-Baskakov-Durrmeyer-Schurer Operators. Further, basic estimates are calculated. In the subsection sequence, rapidity of convergence and order of approximation are studied in terms of first and second order modulus of continuity. We prove a Korovkin-type approximation theorem and obtain the rate of convergence of these operators. Moreover, local and global approximation properties are discussed in different functional spaces. Lastly, A-statistical approximation results are presented. [ABSTRACT FROM AUTHOR]

25. Modified Szász-Mirakjan operators fixing exponentials.

Author

Devdhara, Ankita, Rathour, Laxmi, Mishra, Lakshmi Narayan, and Mishra, Vishnu Narayan

Subjects
EXPONENTIAL functions
Abstract

This research article presents modified Szász-Mirakjan operators that fix exponential spaces. We derive moments and central moments, convergence rate and approximation results of the operators in weighted exponential spaces. The graphical analysis shows that our operator gives better results with exponential functions. [ABSTRACT FROM AUTHOR]

26. New class of beta type operators approximating integrable function

Author

Bhatt, Dhawal J., Mishra, Vishnu Narayan, and Jana, Ranjan Kumar

Abstract

In the present paper we develop a new form of Kantorovich-type operators involving the beta function and study their approximation properties. By using Korovkin’s theorem, we achieve the uniform convergence of sequence of these operators. We obtain the rate of convergence in the sense of modulus of continuity, second order modulus of continuity, Peetre’s K-functional and Lipschitz class. We establish the Voronovskaja type asymptotic result for these operators and the convergence of these operators in a weighted space. At last the graphical comparison of these newly defined operator with few of the fundamental but significant operators is discussed.

27. On multi-valued nonexpansive mappings in UCBS.

Author

Dewangan, Kiran, Rathour, Laxmi, Mishra, Vishnu Narayan, and Raiz, Mohd

Subjects
*NONEXPANSIVE mappings, *SET-valued maps, *BANACH spaces
Abstract

In this manuscript, we focus on the approximation of fixed points for multivalued nonexpansive type mappings within uniformly convex Banach spaces. To achieve this goal, we utilize a three-step iteration scheme that was originally introduced by Ullah et al. Furthermore, we establish the rapid convergence properties of the Ullah et al. iteration scheme through the implementation of numerical examples using Matlab software. [ABSTRACT FROM AUTHOR]

28. Trapezoidal Neutrosophic Teaching Learning-Based Optimization in Enhancing Accuracy of Diabetes Prognosis

Author

Nivedita, Agrawal, Seema, Kumar, Tarun, Kumar, Kapil, Sharma, M.K., and Mishra, Vishnu Narayan

Abstract

Diabetes is one of chronic diseases in which blood glucose (sugar) level soar up high where human body are incapable to absorb it properly. It is important to have an appropriate diagnosis for proper management and treatment. The aim of this manuscript is to provide a more accurate diabetes prediction model through the new adaptive Trapezoidal Neutrosophic Teaching Learning-Based Optimization (TLBO) method. In order to address the inherent uncertainties and imprecisions in medical data, the suggested model makes use of the resilience of Trapezoidal Neutrosophic sets. The Trapezoidal Neutrosophic set theory provides a suitable basis for developing rule/knowledge-based systems in the medical field. The present investigation makes use of the dataset acquired from the Pima Indians Diabetes Database (PIDD) website, which has an extensive global collection of diabetes datasets. The performance of our model is evaluated against several existing methodologies, including Intuitionistic Neuro-Fuzzy System (INFS) Structure, Fuzzy Logic based Diabetes Diagnosis System (FLDDS), Fuzzy Verdict Mechanism (FVM) for Diabetes Decision, (Fuzzy Expert System) FES, and Hierarchical Neuro-Fuzzy Binary space partitioning System (HNFB-1). Quantitative analysis validates that proposed methodology achieves an exceptional predictive accuracy of 99.89%, which is substantially higher than the comparative methodologies, namely INFS Structure (88.76%), FLDDS (87.2%), FVM for Diabetes Decision (85.03%), FES (81.7%), and HNFB-1 (78.26%). These enhancements demonstrate show how well the suggested model works to lower diagnostic errors and increase dependability.

Abstract

We present a case of a 56-year-old female with rheumatoid arthritis (RA) who has been on methotrexate for 9 years and has been complaining of high-grade fever for the past 1 month with no localizing signs and symptoms. She was thoroughly evaluated before being labeled as pyrexia of unknown origin. Histoplasmosis was suspected after bone marrow aspiration smear examination. The presence of histoplasma antigen in the urine confirmed our diagnosis. Fever responded after 2 weeks of liposomal amphotericin B and patient discharged in stable condition on tablet itraconazole., (© Journal of the Association of Physicians of India 2024.)
