Scholars from different perspectives agree that agritourism can be the right tool to balance needs of tourists with those rural communities, offering real opportunities for economic and social development, while mitigating undesirable impacts on environment. This paper aims provide a holistic outlook under which scientific literature deals topic as means support sustainable development areas. To reach this aim, we performed systematic review in order point out linkages between...

In this mathematical study, the effect of buoyancy parameters along with radiation on magneto-hydrodynamic (MHD) micro-polar nano-fluid flow over a stretching/shrinking sheet is taken into consideration. Suitable similarity variables are used to convert governing non-linear partial differential equations system coupled ordinary which then numerically solved by R.K method shooting scheme. The influence pertinent velocity profile, temperature micro-rotation and concentration profile...

The present paper explores a high-order nonlinear Schrödinger equation in non-Kerr law media with the weak non-local nonlinearity describing solitons' propagation through optical fibers. To this end, real and imaginary parts of model are firstly extracted using wave variable transformation. modified Kudryashov method symbolic computations then adopted to successfully retrieve solitons model. results presented current study demonstrate great performance handling equations.

Traditional data analytics tools are designed to deal with the asymmetrical type of i.e., structured, semi-structured, and unstructured. The diverse behavior produced by different sources requires selection suitable tools. restriction recourses a huge volume is challenge for these tools, which affects performances tool’s execution time. Therefore, in present paper, we proposed time optimization model, shares common HDFS (Hadoop Distributed File System) between three Name-node (Master Node),...

Abstract This article concerns a class of nonlocal fractional Laplacian problems depending three real parameters. More precisely, by using an appropriate analytical context on Sobolev spaces due to Servadei and Valdinoci (in order correctly encode the Dirichlet boundary datum in variational formulation our problem) we establish existence weak solutions for equations via recent abstract critical point result differentiable parametric functionals recently proved Ricceri.

An algorithmic method is proposed to generate all cubic polynomials with a critical orbit relation. We curves (polynomials of parameters) that correspond those functions relations. The irreducibility the obtained left as an open problem. Our approach also works relations in families rational active points.

We show that the discrete real option game model proposed in recent literature can be extended to case of imperfect information. As a result, cover wider range applications. However, we also observe effectiveness implementing subsidy is affected by informational structure.

Abstract In this paper we study a weaker form of the classical concept Menger property. This property, called weakly Menger, is independent from property and almost particular, for Tychonoff spaces are not equivalent to spaces. We give some characterizations in terms regular open sets continuous mappings. also introduce star-Menger notion γk -set. Some questions given.

This study introduces a new and promising stability approach for Caputo-Fabrizio (CF)-fractional-order system. A fractional comparison principle this nonsingular kernel derivative is proposed. Next, key inequality suggested to analysis the Lyapunov-based of assumed systems. Afterwards, class-K functions are established Lyapunov direct method. At last, an explanatory example given validate proposed idea. novel can be expanded other types derivatives due simple effective idea beyond procedure.

In this paper, we consider a vertically positioned cylindrical filtering element. Filtering occurs in the radial direction, therefore, direction of velocities liquid and suspended particles coincide with direction. The flow can be considered to one-dimensional radially axisymmetric. To describe such process, axisymmetric Stefan problem will formulated. mass balance formalism Darcy’s law are utilized obtain basic equation for cake filtration. boundary condition at moving surface is derived...

Abstract The main objective of the paper is to analyze how policymakers influence random oligopolistic market equilibrium problem. To this purpose, optimal control conditions are introduced.
