Abstract The purpose of the present investigation is to examine heat, mass and microorganism concentration transfer rates in magnetohydrodynamics (MHD) stratified boundary layer flow tangent hyperbolic nanofluid past a linearly, uniform stretching surface comprising gyrotactic microorganisms as well nanoparticles. governing PDEs with relevant end point conditions are molded into non-dimensional...

Fuzzy clustering is well known as a robust and efficient way to reduce computation cost to obtain the better results. In the literature, many robust fuzzy clustering models have been presented such as Fuzzy C-Mean (FCM) and Possibilistic C-Mean (PCM), where these methods are Type-I Fuzzy clustering. Type-II Fuzzy sets, on the other hand, can provide better performance than Type-I Fuzzy sets, es...

Penelitian ini membahas tentang analisis kecepatan dan temperatur di sekitar titik stagnasi terendah pada magnetohidrodinamika fluida nano yang melewati silinder berpori. Persamaan pembangun diperoleh dari persamaan dimensional, yaitu kontinuitas, momentum, energi. dimensional tersebut kemudian ditransformasikan menjadi nondimensional menggunakan parameter-parameter variable-variabel nondimensi...

The difficulties with the simple shooting method for the solution of ordinary differential boundary value problems are well known, and there have been many suggested modifications to overcome them. Notable among them are the discrete orthonormalization process of Godunov and Conte (1966), the multiple shooting method (Keller(1968) and Osborne(1969)) and the Riccati transformation method (Scott(...

Compared to the hydrostatic hydrodynamic model, the non-hydrostatic hydrodynamic model can accurately simulate flows that feature vertical accelerations. The model’s low computational efficiency severely restricts its wider application. This paper proposes a non-hydrostatic hydrodynamic model based on a multithreading parallel computing method. The horizontal momentum equation is obtained by in...

Context. The asteroseismology of rapidly rotating pulsating stars is hindered by our poor knowledge of the effect of the rotation on the oscillation properties. Aims. Here we present an asymptotic analysis of high-frequency acoustic modes in rapidly rotating stars. Methods. We study the Hamiltonian dynamics of acoustic rays in uniformly rotating polytropic stars and show that the phase space st...

It has been observed that grammaticality judgments do not necessarily reflect relative corpus frequencies: it is possible that structure A is judged as more grammatical than structure B, whereas at the same time structure B occurs more often in actual language data than structure A. In recent work (Boersma & Hayes 2001), we have used Stochastic Optimality Theory to model grammaticality judgment...

The Einstein-Brillouin-Keller EBK quantization equation is used to determine the energy levels of a two-body system with an arbitrary central potential that allows for bound states. The treatment is based on the conservation laws and avoids both the Newtonian and Schrödinger differential equations. Because analytic solutions for the energy levels do not exist in general, the EBK condition is ap...
