Intransitive Permutation Groups with Bounded Movement Having Maximum Degree
Get PDFLet G be a permutation group on a set with no fixed points in and let m be a positive integer. If for each subset of the size is bounded, for , we define the movement of g as the max over all subsets of . In this paper we classified all of permutation groups on set of size 3m + 1 with 2 orbits such that has movement m . 2000 AMS classification subjects: 20B2
Approximation of The Lower Operator in Nonlinear Differential Games with Non-Fixed Time
Get PDFApproximate properties of the lower operator in nonlinear differential games with non-fixed time are studied
Aanalytical Solution for Motion Around Radiated Varying Mass Body
No full textIn this work we will add the radiation pressure effect of varying mass body to the model of varying mass Hamiltonian function, including Periastron effect. The problem was formulated in terms of Delaunay variables. The solution of the problem was constructed based on Delava β Hansilmair perturbation techniques. Finally we find the first order solution for the problem as time series by calculating the desired order for the D operator and variables
New Numerical Methods for Solving Differential Equations
Get PDFIn this paper, we present new numerical methods to solve ordinary differential equations in both linear and nonlinear cases. we apply Daftardar-Gejji technique on theta-method to derive anew family of numerical method. It is shown that the method may be formulated in an equivalent way as a RungeKutta method. The stability of the methods is analyzed
A Lie Symmetry Solutions of Sawada-Kotera Equation
No full textIn this article, the Lie Symmetry Analysis is applied in finding the symmetry solutions of the fifth order Sawada-Kotera equation. The technique is among the most powerful approaches currently used to achieveprecise solutions of the partial differential equations that are nonlinear. We systematically show the procedure to obtain the solution which is achieved by developing infinitesimal transformation, prolongations, infinitesimal generatorsand invariant transformations hence symmetry solutions of the fifth order Sawada-Kotera equation.
Key Words- Lie symmetry analysis. Sawada-Kotera equation. Symmetry groups. Prolongations. Invariant solutions. Power series solutions. Symmetry solutions
Synthesis, Spectral Characterization, Thermal and In vitro Antimicrobial Studies for Novel Co(II) and Ni(II) Complexes of (N,N'-(1,2-Phenylene)Bis(2-Aminobenzamide)
Get PDFNovel metal complexes of Co(II) and Ni(II) have been prepared from reaction of their different salts with previously prepared ligand (L) namely (N,N'-(1,2-phenylene)bis(2-aminobenzamide). Synthesis ligand and its metal (II) complexes (1-5) were reported and characterized with the help of analytical and physiochemical analysis as elemental, IR spectra, thermal (TG/DTG), UV-Vis, magnetic susceptibility and molar conductance in DMF, On the view of the previous data and measurements, the structure and composition species behave as mononuclear and octahedral geometry has been proposed for all the complexes except for complex (1) adopted tetrahedral structure. Furthermore, the in vitro antibacterial Staphylococcus aureus (ATCC 25923) as Gram-positive strain, Escherichia coli (ATCC 25922) as Gram-negative strain and antifungal Candida albicans (ATCC 10231) have been studied for all samples using disc diffusion method against Ampicillin and Fluconazole as positive controls, respectively. The results show that complexation facilitates the activity of most studied metal complexes than the free ligand
Chemical Speciation and Mobility of Heavy Metals in Soils Around Nasara Sack and Packaging Company Akwanga, Nigeria
Get PDFThis study quantified and assessed the mobility of iron, nickel, cobalt and lead in soils around a sack and packaging company using indices such as mobility factor and risk assessment code. The results evaluating the mobility factor of heavy metals in soils around the sack and packaging company reveal that all the metals determined exceed the minimum limit of 10% mobility factor and are mobile with the mobility factor being in the order of: Ni > Pb > Co > Fe in the test soil. The risk assessment of heavy metals in the area based on risk assessment code ranged from low risk to medium risk (1-30%) where the risk level of the heavy metals is in the order: Co > Ni > Pb > Fe in the test soil

Comparison of Halley-Chebyshev Method with Several Nonlinear equation Solving Methods Methods
Get PDFIn this paper, we present one of the most important numerical analysis problems that we find in the roots of the nonlinear equation. In numerical analysis and numerical computing, there are many methods that we can approximate the roots of this equation. We present here several different methods, such as Halley's method, Chebyshev's method, Newton's method, and other new methods presented in papers and journals, and compare them. In the end, we get a good and attractive result
