Research ArticleOpen accessIn the abstractPoisson Quasi-Maximum Likelihood Estimator-based CUSUM Test for Integer-Valued Time SeriesSangyeol LeeThis study considers the parameter change test for integer-valued time series models based on the Poisson quasi-maximum likelihood estimates. As a change point test, we consider the score vector-based CUSUM test and show that its limiting null distribution takes the form of a function of Brownian bridges. Moreover, the residual-based CUSUM tests are considered as alternatives. For evaluation, we conduct … …Journal of Mathematics and Statistics, Vol. 15, Issue 1 · 1 Oct 2019 · 7,650 accessesView PDF Cite

Research ArticleOpen accessIn the abstractProcess Physics: Emergent Unified Dynamical 3-Space, Quantum and Gravity: A ReviewReginald Thomas CahillExperiments have repeatedly revealed the existence of a dynamical structured fractal 3-space, with a speed relative to the Earth of some 500 km sec-1 from a southerly direction. Experiments have ranged from optical light speed anisotropy interferometers to zener diode quantum detectors. This dynamical space has been missing from theories from the beginning of physics. This dynamical space generates a … …Physics International, Vol. 6, Issue 2 · 4 Aug 2015 · 8,515 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComplexity in Human Perception of Brightness: A Historical Review on the Evolution of the Philosophy of Visual PerceptionKuntal Ghosh, Kamales BhaumikProblem statement: The “eye-brain” complex, which contributes maximally to visual perception, is no doubt a very interesting object for complexity study. In this review we shall try to present some of its aspects in perceiving brightness. It is a well-known fact that the perceived brightness of any surface depends on the brightness of the surfaces that surround it, a phenomenon … …OnLine Journal of Biological Sciences, Vol. 10, Issue 1 · 30 Jun 2010 · 8,680 accessesView PDF Cite

Research ArticleOpen accessIn the abstractQuantum Mechanical Calculation of the Optical Absorption of Silver and Gold Nanoparticles by Density Functional TheoryElham Gharibshahi, Elias SaionProblem statement: Metal nanoparticles confine the motion of conduction electrons and exhibit a strong optical absorption of electromagnetic radiation in the UV-vis-NIR region. The absorption is classically derived from the collective oscillations of free electrons in a metallic nanostructure as a consequence of incident electromagnetic radiation polarizing the particle optically embedded in a dielectric matrix. These oscillations, known as the … …Physics International, Vol. 1, Issue 1 · 31 Mar 2010 · 16,181 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDesign and Optimization of a 1.55 µm Waveguide Based on Silicon Planar Photonic CrystalsR. Bchir, A. Bardaoui, M. Machhout et al.Background: Silicon based Planar Photonic Crystals (PPC) are used for the design of a 1.55 µm waveguide. Line defects are then formed in the PPC structures, by removing rows of holes, to obtain a Planar Photonic Crystal Waveguide (PPCW). Objective: First, we varied the thickness of the Silicon slab and the pore radius in order to obtain optimum design parameters … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 7,472 accessesView PDF Cite

Research ArticleOpen accessIn the abstractStudy of the Optical and Physical Roles of a Dielectric Laser Dye Solvent Which Affects on the Dye Laser OperationRiyad A.M. GhazyIt is well known that when the pump laser beam incidence on the laser dye liquid it will be absorbed. This absorption tends to heat the laser active medium, which is the laser dye solution. In view of this the correlated property of that active medium well change tends to shift the operated frequency and wavelength. Therefore, one of most … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,862 accessesView PDF Cite
