Purpose: The aim of this article is focused on providing numerical solutions for system of second order robot arm problem using the Runge-Kutta Sixth order algorithm. Design/methodology/approach: The parameters governing the arm model of a robot control problem have also been discussed through RK-sixth-order algorithm. The precised solution of the system of equations representing the arm model ...

We generalise the notion of contact manifold by allowing the contact distribution to have codimension two. There are special features in dimension six. In particular, we show that the complex structure on a three-dimensional complex contact manifold is determined solely by the underlying contact distribution. Definitions Suppose M is a 6-dimensional connected oriented smooth manifold and H is a...

Introduction: Experimental Solubilities of sulfamerazine (SMR) and sulfamethazine (SMT) in some (methanol + water), (ethanol water) (1-propanol cosolvent mixtures were collected from the literature at five temperatures 293.15 to 313.15 K. Methodology: The results analyzed with van’t Hoff, Apelblat modified, Buchowski-Ksiazaczak λh, Hoff-Yaws model, twoparameter Weibull function model. It was de...

The potential amplification of primordial seed magnetic fields by gravitational waves was discussed in [1], wherein a mechanism was proposed and an amplification of several orders of magnitude was obtained. Recently, this mechanism was revisited in [2] and the original results were recovered both qualitatively and quantitatively. Despite this, the comparison of the two papers is misleading and ...

We consider the multiplicity of nontrivial solutions of the following quasilinear elliptic system -div(|x|(-ap)|∇u|(p-2)∇u) + f₁(x)|u|(p-2) u = (α/(α + β))g(x)|u| (α-2) u|v| (β) + λh₁(x)|u| (γ-2) u + l₁(x), -div(|x|(-ap) |∇v| (p-2)∇v) + f₂(x)|v| (p-2) v = (β/(α + β))g(x)|v|(β-2) v|u|(α) + μh 2(x)|v|(γ-2)v + l 2(x), u(x) > 0, v(x) > 0, x ∈ ℝ(N), where λ, μ > 0, 1 < p < N, 1 < γ < p < α + β < p* ...

We present general results for the contact process by a method which applies to all transitive graphs of bounded degree, including graphs of exponential growth. The model’s infection rates are varied though a common control parameter, for which two natural transition points are defined as: i. λT , the value up to which the infection dies out exponentially fast if introduced at a single site, an...

A magnetic helix realizes a one-dimensional magnetic crystal with a period given by the pitch length λh. Its spin-wave excitations-the helimagnons-experience Bragg scattering off this periodicity, leading to gaps in the spectrum that inhibit their propagation along the pitch direction. Using high-resolution inelastic neutron scattering, the resulting band structure of helimagnons was resolved b...

The h-super connectivity κh and the h-super edge-connectivity λh are more refined network reliability indices than the connectivity and the edge-connectivity. This paper shows that for a connected balanced digraph D and its line digraph L, if D is optimally super edge-connected, then κ1(L) = 2λ1(D), and that for a connected graph G and its line graph L, if one of κ1(L) and λ2(G) exists, then κ1...

Abstract. Atmospheric gravity waves (GWs) play an important role in atmospheric dynamics but accurately representing them general circulation models (GCMs) is challenging. This especially true for orographic GWs generated by wind flow over small mountainous islands the Southern Ocean. Currently, these lie “grey zone” of global model resolution, where they are neither fully resolved nor paramete...

Contributions of the direct quark mechanism are studied in the nonmesonic weak decays of light hypernuclei. The ΛN → NN transition is described by the one pion exchange mechanism and the direct quark mechanism, induced by the four-quark vertices in the effective weak Hamiltonian. By employing a realistic wave function of the Λ inside the hypernuclei, nonmesonic decay rates of ΛH, 4 ΛHe, and 5 Λ...
