Research ArticleOpen accessIn the abstractMeasures on the Quotient Spaces of the IntegersNorris Sookoo, Peter ChamiSK-partitions were introduced by Sharma and Kaushik, who defined distances (metrics) between vectors in terms of partitions of the alphabet set Fq , the set of the ring of integers modulo q. These distances were applied in Coding Theory. The research examined algebraic and topological aspects of SK-partitions and related sets of measures. A lattice of SK-partitions was introduced and … …Journal of Mathematics and Statistics, Vol. 3, Issue 4 · 31 Dec 2007 · 7,009 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Gamma Irradiation on the Structure Diffusion Coefficient of Co-Zn Doped FerriteDalal Mohammed HemedaA series of the ferrite system Co0.6Zn0.4MnxFe2-xO4 with (x = 0.7, 0.8, 0.9 and 1) were prepared by general ceramic method. The X-ray diffraction patterns confirmed the formation of the cubic single phase structure. The lattice parameter and the crystal size increased after irradiation which was attributed to the formation of ferrous ions of larger radius than that of ferrous … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,728 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Laser Irradiation on the Structural and Electrical Properties of Co-Zn Ferrite Thin FilmNehad M. TashtoushThin films of irradiated and non-irradiated Co-Zn ferrite was prepared by the thermal evaporation method on a glass substrate. The samples were annealed at 200°C, 400°C and 600°C for 1hr. The XRD analysis of all kinds of films, prepared for this study, shows that the spinel phase is almost completed after annealing. The change of the XRD after annealing is … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 7,033 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordHomomorphisms on Lattices of MeasuresNorris Sookoo, Peter ChamiProblem statement: Homomorphisms on lattices of measures defined on the quotient spaces of the integers were considered. These measures were defined in terms of Sharma-Kaushik partitions. The homomorphisms were studied in terms of their relationship with the underlying Sharma-Kaushik partitions. Approach: We defined certain mappings between lattices of Sharma-Kaushik partitions and showed that they are homomorphisms. These homomorphisms were mirrored … …Journal of Mathematics and Statistics, Vol. 5, Issue 4 · 31 Dec 2009 · 7,004 accessesView PDFCite

Mohamad Al-Asfoor et al.Problem statement: The aim of this research was to study the effect of Sr substitution on structure and thermal diffusivity of Bal-xSrxTiO3 ceramic at room temperature. Approach: Structural and thermal diffusivity of Ba1-xSrxTiO3 were studied by performing X-ray diffraction and photoflash measurements. The effects of Sr substitution on the structure and on the thermal diffusivity of Ba1-xSrxTiO3 (0≤x≤1) were investigated. … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 8,773 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordFlexible Stem Trabecular ProsthesesRaffaella Aversa, Florian Ion T. Petrescu, Relly Victoria V. Petrescu, Antonio ApicellaThe complex biomechanics and morphology of the femur proximal epiphysis are presented. This specific region in human femur is characterized by a high flexibility compared to that of other primates, since evolved lighter and longer due to the human verticalposition and more balanced loading. The nature and fine morphology of the femur head and its structural behavior have been investigated. … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 22 Dec 2016 · 7,855 accessesView PDFCite
