A post-processing tool for experimental data is developed to rebuild the instantaneous and local distributions of fuel port diameter regression rate throughout conduct during a firing test. The main objective use methodology be able, at given instant test, simulate hybrid rocket engine configuration validate related numerical modeling. based on coupling between mass flow obtained by ballistic r...

Background: One of the key objectives is to update knowledge in order to develop treatment and care recommendations based on research findings. The purpose of the present meta-analysis was to compare the survival rate of narrow dental implants (NDI) with standard dental implants (SDI).    Methods: The international databases targeted for conducting a broad search included PubMed (Medline), Sco...

YOYO is a deterministic model developed to represent the growth and vertical movement of Microcystis sp. colonies in the water column. Migration of colonies is represented in the model through the dynamics of carbon-reserve metabolism during photosynthesis and biosynthesis. It was used to quantify combined impacts of light, temperature and mixing on the growth and migration of colonies with dif...

Knödel graphs Wd,n are regular graphs on n vertices and degree d. They have been introduced by W. Knödel and have been proved to be minimum gossip graphs and minimum broadcast graphs for d = blog nc. They became even more interesting in the light of recent results regarding the diameter, which is, up to now, the smallest known diameter among all minimum broadcast graphs on 2 vertices. Also, the...

The Harmonic index $ H(G) $ of a graph $ G $ is defined as the sum of the weights $ dfrac{2}{d(u)+d(v)} $ of all edges $ uv $ of $G$, where $d(u)$ denotes the degree of the vertex $u$ in $G$. In this work, we prove the conjecture $dfrac{H(G)}{D(G)} geq dfrac{1}{2}+dfrac{1}{3(n-1)}  $ given by Jianxi Liu in 2013 when G is a unicyclic graph and give a better bound $ dfrac{H(G)}{D(G)}geq dfra...

Given a compact connected set E in the unit disk B2, we give new upper bound for conformal capacity of condenser (B2,E) terms hyperbolic diameter t E. Moreover, t>0, construct and apply novel numerical methods to show that it has larger than with same diameter. The is called Reuleaux triangle geometry constant width equal t.
