A novel distance measure for intuitionistic fuzzy sets and their application in pattern classification, medical diagnosis, and career determination

Potwary, Joydeep; Patel, Anjali; Jana, Subhankar; Mahanta, Juthika

2024 International Journal of Computing Science and Mathematics

doi:10.1504/ijcsm.2024.137834

This study investigates some existing distance measures for intuitionistic fuzzy sets (IFSs). Existing distance measures have several drawbacks such as division by zero, counterintuitive and unreasonable results, violation of the fundamental properties of intuitionistic fuzzy distance measures....

A numerical study on the effects of branch numbers on the vibration characteristics of the engine fuel manifold system

Hou, Yunzhe; Zhang, Haoyang; Cheng, Guanbing; Peng, Hongbo

2024 International Journal of Computing Science and Mathematics

doi:10.1504/ijcsm.2024.137823

The modal analysis of fuel pipelines was done by experimental modal vibration measurement. The physical and calculated models of the fuel manifold with various branches were established to examine the effects of branch numbers on manifold system structural parameters. The results show that the...

Two-machine reentrant circular robotic cells with swap ability

Khebouche, Ali; Boudhar, Mourad

2024 International Journal of Computing Science and Mathematics

doi:10.1504/ijcsm.2024.137825

We consider a robotic cell consisting of two machines placed circularly and a robot with swap ability, operating under the constraint of a reentrant chain where a processed part must return to the first machine. The objective is to determine the optimal cycle time for one unit to maximise...

A model of the influence of agricultural customer perceived value

Li, Donghui; Zhang, Guozheng; Wang, Fang; Peng, Li; Shi, Yongdong

2024 International Journal of Computing Science and Mathematics

doi:10.1504/ijcsm.2024.137842

The customer perceived value (CPV) of agricultural products may differ dramatically from that of other items due to the superior quality and safety attributes of agricultural products. This research proposes a model of agricultural customer perceived value (ACPV) based on the quality and safety...

Redefine trigonometric cubic B-spline collocation scheme for solving convection-diffusion equation

Rawat, Ashish Kumar; Dhiman, Neeraj; Chauhan, Anand; Gupta, Saumya

2024 International Journal of Computing Science and Mathematics

doi:10.1504/ijcsm.2024.137829

Redefining the formulation of the trigonometrical cubic B-spline, collocation-based scheme is used to approximate the numerical solution of the convection-diffusion partial differential equation (PDE). This proposed work is based on the usual discretisation of the linear and non-linear terms of...

Adaptive hand image function region segmentation for intelligent aided diagnosis

Liu, Yang; Jie, Jing; Zheng, Hui; Hou, Beiping; Li, Zhenglin

2024 International Journal of Computing Science and Mathematics

doi:10.1504/ijcsm.2024.137833

Smart hand diagnosis simulates the expert knowledge of hand diagnosis in traditional Chinese medicine and makes a diagnosis through the hand image information. To ensure the correctness of the diagnosis, an adaptive hand image function region segmentation is developed. Firstly, a hand image is...

An application of rough set theory to predict telecom customer churn

Binh, Tu Van; Thy, Ngo Giang

2024 International Journal of Computing Science and Mathematics

doi:10.1504/ijcsm.2024.137800

The current paper applies algorithms of machine learning to predict customer churn. The study employs 211,777 instances in the telecommunication sector with six attributes employed, e.g., data, length of stay, top-up, external communication, handset of phone, and churn. Although the rules...

A generalised quadrature of order four for analytic functions

Mohanty, Sanjit Kumar; Dash, Rajani Ballav

2024 International Journal of Computing Science and Mathematics

doi:10.1504/ijcsm.2024.137846

This paper introduces a novel approach to formulating n-rule combinations departing from traditional mixing up of rules, which is termed as generalised quadrature method. In this process, a bunch of quadrature rules of lower precisions are mixed to form a generalised quadrature rule of higher...
