  • Detection of optic disc centre point in retinal imageDetection of optic disc centre point in retinal image

    Abstract – Glaucoma and diabetic retinopathy (DR) are the two most common retinal related diseases occurred in the world. Glaucoma can be diagnosed by measuring optic cup to disc ratio (CDR) defined as optic cup to optic disc vertical diameter ratio of retinal fundus image. A computer based optic disc is expected to assist the ophthalmologist t...

  • Application of air quality index and inverse distance weighting for mapping the distribution of air pollution at several urban districts of Hanoi cityApplication of air quality index and inverse distance weighting for mapping the distribution of air pollution at several urban districts of Hanoi city

    Abstract. The air pollution level can be assessed using air quality index - AQI calculated from the concentration of some gases and particle matters which are measured at ambient air quality monitoring stations. The calculated AQI values are characterized by temporal continuity but spatial discontinuity. However, AQI values of each monitoring s...

  • On the existence and uniqueness of solutions to 2D g-benard problem in unbounded domainsOn the existence and uniqueness of solutions to 2D g-benard problem in unbounded domains

    The existence and long-time behavior of solutions in terms of existence of an attractor for the 2D B´enard problem have been studied in [3] in the autonomous case and in [1] in the non-autonomous case. The 2D g-Navier-Stokes equations and its relationship with the 3D Navier-Stokes equations in the thin domain Ω g was introduced by Roh in [12]....

  • Depletion density of ideal gas Bose-Einstein condensate by two parallel platesDepletion density of ideal gas Bose-Einstein condensate by two parallel plates

    1. Introduction It is well-known that the system of indistinguishable Bose particles is not affected by the Heisenberg uncertainty principle. Thereby, the particles are allowed to occupy the same state [1]. For a system of Bose gas, a number of the atoms will be condensed when the temperature is decreased to a critical temperature TC. Theoretic...
