The core goal of the article is to inspect the effect of thermally radiative heat transmission and heat source on peristalsis of a couplestress liquid in the asymmetric microfluidics conduit. The normalized 2D flow governing equations for momentum and energy are balanced using non dimensional quantities and simplify using the approximation wavelength is so long compared with Reynolds number is too small. All the solutions like velocity flow and temperature profile are illustrated with MATLAB software under the effects of important parameters like Hartmann number, Darcy number, Prandtl number, heat source/sink parameter and thermal radiation parameter. It is observed that increasing in Prandtl (Pr) number and Eckert (E) number will lead to increase in temperature distribution. These types of observations may be applicable to develop EMHD for drug delivery system and blood transport in micro vessels. [ABSTRACT FROM AUTHOR]

The squeezing effect of a curved circular plate moving normal towards a lower porous plate in the presence of a magnetic field consisting of an electrically conducting non Newtonian couple stress fluid is considered. The film shape is taken to be secant. Suitable expression for pressure is obtained taking into consideration viscosity variation and MHD effects. [ABSTRACT FROM AUTHOR]

The movement of a Williamson fluid is studied in a micro asymmetric walls and it is initiated by the movement of peristalsis waves with the constant speed, however with distinct amplitudes and phase on the stretchy walls under LWL wavelength and LRN assumption. The perturbation method in the power of We is constructed to get explicit forms for velocity, pressure rise, frictional forces and shear stress. The properties of several developing parameters on the fluid motion are presented graphically. In addition, the streamlines prototype is designed and it is examined that trapping happens near the walls and the magnitude of the trapped bolus varies with changing inserted flow parameters.

In the present situation COVID-19 global pandemic, an overall world got embrace with covid-19 virus. Moreover every country went under quarantine and firm mitigation measures by temporary shutdown in people crowded place like schools, restaurants, theatres and domestic and international transport facilities[1]. So government made these measures to be effective to support and compliance of public[2]. Advanced medical technology put up with new vaccines to control infection of virus. Vaccination is one of the most effective step to control the virus from affecting the entire population. This paper aims to explore the optimal effectiveness of Vaccination for novel COVID-19 non clinical approach. We need smart solutions and decisions to mitigate the coronavirus's impact. We formulate the mathematical model to Analyse the vaccination effectiveness[3]. The objective function is designed to reduce both awareness of vaccination and effectiveness of vaccination using WHO data/ Indian dashboard data[4]. The degree of protection As a part we can analyse the risk factors of immunization using multivariate models using statistical analysis. [ABSTRACT FROM AUTHOR]

In this manuscript we use the new fuzzy model called ASFCM, to study the problems of middle class family. Here we deal with families on a particular group, here we take all the families according to their income. For the group of expert opinions associated with the analysis of family problem happen to vary widely as they are all from different categories. These expert’s opinions varies according to their income. So this new technique, which we have introduced, is found to be a relevant tool in the analysis of the problem under investigation. This manuscript has 3 parts. Section one is introduction of the new notion of Average Super Fuzzy Cognitive Maps (ASFCMs). Section two deals the application of the new technique to the family problems. The third section gives the conclusions. The ankle-brachial index (ABI) is defined as the ratio of the Systolic Blood Pressure (SBP) measured at the ankle to the SBP measured at the brachial artery. Studies show that ABI can also indicate atherosclerosis at various vascular sites. Therefore it can be used as a prognostic marker tool for cardiovascular events and functional impairments, even in the absence of symptoms of peripheral artery diseases (PAD). The standard threshold value of ABI value of 0.9 appears to be lower in patients with complications. A pilot study has been conducted on 77 subjects. Results show that ABI measurement can be used as a screening tool for PAD but requires further larger study for its consolidation. [ABSTRACT FROM AUTHOR]

The blood movement of a Williamson fluid with uniform applied magnetic field is studied in a micro-channel produced by the transport of the waves of peristalsis by the unchanged speed however having distinct amplitudes and phase on the elastic walls. The article is also expressed and examined by a regular perturbation sequences of a Weissenberg number as a parameter. We further obtain an explicit design for the axial velocity and the pressure gradient up to the first order.

Credit Risk Analysis is a process adapted by loan associations to evaluate the risk -based pricing for sanctioning loans. The chances of approving loans depend on the customer's credit score, which includes annual income, banking history, loan, insurance and different elements of risks such as default risk, credit correlation risk, collateral risk, credit concentration risk, rating migration risk and recovery risk. Results of the calculation allow lenders and customers to assess credit profile characteristics. Data Science allows discovering of new patterns within a complex data set which can be an efficient method to compute risk percentage by means of non – hierarchical clustering. K-means is an iterative algorithm - the idea is to use small unstructured groups of data of fixed size, assigned to clusters to be stored in the memory depending on the previous locations of the cluster centroids. It is validated that the suggested technique predicts better accuracy, is a faster and targeted approach than existing methods. [ABSTRACT FROM AUTHOR]

In this paper an oscillatory stream of anelectrically and viscoelasticleading liquid through a porous medium limited by two interminable vertical similar plates is talked about within the sight of heat source and radiation with impact of mass transfer and slip parameter. One of these plates is exposed to a slip-stream condition and other to a no-slip condition. The weight inclination in the channel wavers with time. An attractive field of uniform quality is connected toward the path opposite to the plates. The initiated attractive field is disregarded because of suspicion of little attractive Reynolds number. The temperature contrast of the two plates is additionally accepted sufficiently high to instigate heat transfer because of radiation. A shut form investigative answer for the issue is acquired. The investigative outcomes are assessed statistically and afterward exhibited graphically to talk about in part the impacts of various relevant constraints going into the issue. It is established that the speed profiles increment because of increment in Reynolds number or there is increment in Grashof number for mass transfer and a switch number is noted on the profiles of the speed at whatever point there is an expansion in either attractive parameter or heat source parameter.

Magneto hydrodynamic (MHD) varied convection stream of a thick, incompressible and electrically directing liquid in a perpendicular channel is examined logically. An attractive field of uniform quality is connected opposite to the planes of the channel dividers. The liquid is followed up on by an intermittent variety of the weight angle the vertically upward way. The temperature of one of the plates is non-uniform and the temperature complexity of the dividers of the channel is adequately high to prompt warmth exchange in light of radiation. The liquid and the divert turn as one with a precise speed about the hub ordinary to the plates of the channel. An careful logical arrangement of the issue is gotten. It is found that the speed profiles decrease because of increase in either Reynolds number (or) Hartmann number (or) radiation parameter. The temperature profiles increases steadily due to either in radiation parameter concentration profiles increase because of increase in rotation parameter (or) Schmidt number (or) chemical reaction parameter.
