Finite difference solution othird order viscous wave equation
(International journal of engineering, science and mathematics, 2014)A new numerical method for Nwogu’s (ASCE Journal of Waterway, Port, Coastal and Ocean En-gineering1993;119:618) two-dimensional extended Boussinesq equations is presented using a lineartriangular nite element spatial ... -
Mixed galerkin inite element solution of the homogenous burgers equation
(International journal of engineering & scientific research, 2015)Nonlinear partial differential equations arise in a large number of mathematical and engineering problems. Systems of nonlinear partial differential equations have attracted much attention in studying solid state physics, ... -
Generation for measurable covers for measurable sets using multiple integral of functions
(Science sign post publishing, 2015)The point-objective problem and the Weber problem are two well-known formulations for locating a new facility with respect to a set of fixed facilities. When locations are represented as points on a plane, the point-objective ... -
On unconditional banach space ideal property
(Instytut matematyczny polskiej akademi nauk, 2015-03-18)We show that a Banach space with separable dual can be renormed to satisfy hereditarily an "almost" optimal uniform smoothness condition. The optimal condition occurs when the canonical decomposition X∗∗∗=X⊥⊕X∗ is ... -
Wavelet sets in ℝ n
(Council for innovative research, 2015-06-18)A congruency theorem is proven for an ordered pair of groups of homeomorphisms of a metric space satisfying an abstract dilation-translation relationship. A corollary is the existence of wavelet sets, and hence of ... -
Perfect repetition codes of ideals of the polynomial ring 2 [ ] ( 1) n n F x mod x − for error control in computer applicatons
(2016)The study of perfect codes has attracted a lot of interest among researchers in coding theory in view of the fact that many authors have indicated that this type of codes is rare. These codes are considered the best for ... -
Unconditional ideals in Banach spaces
(Scientific advances, 2012-07-14)Let wL ′ denote the assignment which associates with each pair of Banach spaces X , Y, the vector space L ( ) X Y w , ′ and K(X, Y ) be the space of all compact linear operators from X to Y. Let T L ( ) X Y w , ′ ∈ and ... -
Characterization of codes of ideals of the polynomial ring f30 2 [x] mod ô€€€ x30 ô€€€ 1 for error control in computer applicatons
(2016-06-30)The study of ideals in algebraic number system has contributed immensely in preserving the notion of unique factorization in rings of algebraic integers and in proving Fermat's last Theorem. Recent research has revealed ... -
Spaces of compact operators and their dual spaces
(Business mathematics and informatics, 2002)Theω′-topology on the spaceL(X, Y) of bounded linear operators from the Banach spaceX into the Banach spaceY is discussed in [10]. Let ℒw' (X, Y) denote the space of allT∈L(X, Y) for which there exists a sequence of compact ... -
Equivalent Banach operator ideal norms1
(Hikari: International Journal of mathematical analysis, 2012-12-01)We present some results concerning the general theory of Banach ideals of operators and give several applications to Banach space theory. We give, in Section 3, new proofs of several recent results, as well as new operator ... -
Advances in composite integer factorization
(2013)In this research we propose a new method of integer factorization. Prime numbers are the building blocks of arithmetic. At the moment there are no efficient methods (algorithms) known that will determine whether a ... -
Algebraic approach to composite integer factorization
(International journal of mathematics and statistics, 2013)There various algorithms that can factor large integers but very few of these algorithms run in polynomial time. This fact makes them inefficient. The apparent difficulty of factoring large integers is the basis of some ... -
On convergence of sections of sequences in Banach spaces
(Springer-verlag, 2000-02-01)An elementary proof of the (known) fact that each element of the Banach spaceℓ w p (X) of weakly absolutelyp-summable sequences (if 1≤p<∞) in the Banach spaceX is the norm limit of its sections if and only if each element ... -
On summing multipliers and applications
(Academic press, 2001-01-01)A scalar sequence (αi) is said to be a p-summing multiplier of a Banach space E, if ∑∞i = 1‖αixi‖p < ∞ for all weakly p-summable sequences in E. We study some important properties of the space mp(E) of all p-summing ... -
Income source diversification and financial performance of commercial banks in Kenya
(Mku Journals, 2011-01-21)The profitability of commercial banks depends heavily on the net of income generating activities and the related activities’ expense. Due to the problem of profitability and stiff competition in the industry, commercial ... -
Nonparametric estimator for the standardized sum using edgeworth expansions
(International Journal of Scientific Research, 2018-02-01)Constructing an estimator for functional estimation is one of the problems in statistical inference. In this paper, the problem of constructing an estimator for a studentized sum is considered in the nonparametric set-up. ... -
School factors as correlates of secondary students’ achievement in mathematics in Bungoma County, Kenya
(International Journal of Educational Investigations, 2015-10-01)There is abundant research evidence to support the view that when Mathematics is taught in an enabling environment, a lot of enjoyable learning takes place. But in reality this is not always so, the implication is that ... -
Projected rainfall and temperature changes over Bungoma County in western kenya by the year 2050 based on PRECIS modeling system
(Ajol: Ethiopian Journal of Environmental Studies & Management, 2016-06-19)This study investigated projected changes in rainfall and temperature over Bungoma County by the year 2050 based on the Intergovernmental Panel on Climate Change (IPCC) Special Report on Emission Scenarios (SRES) A1B and ... -
Forensic estimation of time of death: a mathematical model
(International Journal of Management,IT and Engineering (IJMIE), 2013-07-01)In this paper we establish the exact time of death of a murdered person. This leads to an ordinary differential equations whose solution has been analyzed to provide the approximate time of death. Forensic expert will try ... -
