Research ArticleOpen accessEvery word in the titleAutomated Position System Implementation over Vehicular Ad Hoc Networks in 2-Dimension SpaceSoumen Kanrar, Mohammad SirajProblem statement: The real world scenario have changed from the wired connection to wireless connection. Over the years software development has responded to the increasing growth of wireless connectivity in developing network enabled software. The problem arises in the wireless domain due to random packet loss in transport layer and as well as in data link layer for the end … …Journal of Computer Science, Vol. 6, Issue 2 · 28 Feb 2010 · 7,196 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Banach space mp(X), for 1 ≤ pNaim L. BrahaProblem statement: In the theory of Banach spaces one of the problems which describes geometric property of Banach spaces is Banach-Saks Property. In this context we were known many Banach spaces which had this property such as Lp[0, 1] for 1 < p ≤ 2. Approach: Following the sequential structure of the Banach sequence space mp(X), for 1 ≤ p … …Journal of Mathematics and Statistics, Vol. 5, Issue 1 · 31 Mar 2009 · 7,772 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOn a Class of Nonhomogeneous Fields in Hilbert SpaceRaéd HatamlehTwo-parametric semigroups of operators in Hilbert space with bounded infinitesimal doubly commuting operators are studied. The characteristics describing deviation of a semigroup from unitary one, when infinitesimal operators are unitary, in particular, nonunitary index, have been introduced. Necessary and sufficient conditions for nonunitary index finiteness have been obtained. …Journal of Mathematics and Statistics, Vol. 3, Issue 4 · 31 Dec 2007 · 6,686 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIntensity Position Modulation for Free-Space Laser Communication SystemF. Faghihi, A. JangjooIn this study a novel analog modulation-demodulation technique for free-space laser communication system called Intensity Position Modulation (IPM) is carried out. According to TEM00 mode of a laser beam and by linear fitting on the Gaussian function as an approximation, the variation of the linear part on the reverse biased pn photodiode produced various currents. Our simulated results show fine … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 6,603 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBirkhoff Orthogonality and Different Particular Cases of Carlsson's Orthogonality on Normed Linear SpacesPrakash Muni Bajracharya, Bhuwan Prasad OjhaLet x, y ∈ X, where X is an inner-product space. We say x is orthogonal to y if ⟨x, y⟩ = 0. When we move to general normed spaces there are many possibilities of extending the notion of orthogonality. Since 1934, different types of orthogonality relations in normed spaces have been introduced and studied. In this study, we enlist … …Journal of Mathematics and Statistics, Vol. 16, Issue 1 · 22 Jul 2020 · 6,274 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOn the Construction and Properties of Lattice-Group Structure in Cartesian Product SpacesDavronbek Malikov, Susmit BagchiThe lattice theory and group algebra have several applications in computing sciences as well as physical sciences. The concept of lattice-group structure is an interesting hybrid algebraic structure having potential applications. In this paper, the algebraic construction of lattice-group structure is formulated and associated algebraic properties are established. The proposed construction considers Cartesian product spaces. The concept of two-dimensional monoid … …Journal of Computer Science, Vol. 16, Issue 4 · 3 Apr 2020 · 7,839 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGenetic Diversity of Leifsonia xyli Subsp. xyli Causing Ratoon Stunting Diseases of Sugarcane in Indonesia Using Intergenic Spacer Region Sequence AnalysisSisca Prayudani Usman, Abdul Latief Abadi et al.Leifsonia xyli subsp xyli (Lxx) is the cause of Ratoon Stunting Disease (RSD) on sugarcane and it considers as a quarantine pest in certain regions of Indonesia. RSD is a systemic disease that causes severe cane yield loss. Information about genetic diversity of this bacterial pathogen in Indonesia is limited. While global trading of sugar cane seed may facilitate the … …OnLine Journal of Biological Sciences, Vol. 25, Issue 2 · 23 Jun 2025 · 3,358 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSome Generalized Fixed Point Theorems of Contraction Type Mappings in Quasi Metric SpacesSahar Mohamed Ali Abou BakrThis paper adjusts conditions on new defined given the name {a, d, c; r} ctype of contraction mappings on complete quasi metric space, confirms that there is only one fixed of any of these mappings with these adjustments, extends and generalizes results given in some previous research papers, and then builds a convergence theorem for a sequence of fixed points … …Journal of Mathematics and Statistics, Vol. 13, Issue 4 · 16 Oct 2017 · 7,208 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSplit-Quaternionic Representation of the Moving Frame for Timelike Surfaces in 3-Dimensional Minkowski SpacetimePaul BrackenThe moving frame and associated Gauss-Codazzi equations for surfaces in Minkowski three space are introduced. A split-quaternionic representation is used to identify the Gauss-Weingarten equations with a Lax pair representation. This Lax pair representaion is calculated and given explicitly. …Journal of Mathematics and Statistics, Vol. 6, Issue 1 · 31 Mar 2010 · 7,730 accessesView PDFCite
