To ensure that the missile is safely separated from internal weapons bay, jet used to control process of separation, which mounted on front edge bay. The length-to-depth ratio bay was L/D=8, diameter d1 =0.178 m, d2 =0.05 m . FLUENT software combined with our group-developed code under platform a user-defined function (UDF) solve flow field and six-degrees-of-freedom (6DOF) missile. detached ed...

Underwater rock-plug blasting is a special technique for excavating underwater inlets. In the process of excavation, blasting-block movement from difference in water pressure inside and outside tunnel one key factors successful construction. Laboratory experiments were conducted using small explosive charges, high-speed camera was adopted to observe study block motion. Then, numerical simulatio...

The liquid film formed around the inner walls of a small horizontal circular pipe often exhibits non-uniform distributions circumferentially, where is thinner at top surface than bottom one. Even with this known phenomenon, problem remains challenging task for Computational Fluid Dynamics (CFD) to predict formation on walls, mainly due inaccurate two-phase flow models that can induce an undesir...

in this paper among many other things we prove that the topological left amenability and left amenability of a weighted hypergroup (k, ?) are equivalent. for a normal subgroup h of k, we define a weight function ?? on kih and obtain connection between left amenability of (k, ?) and (k|h, ??). let h be a compact subhypergroup of k. we define the weight function on k||h and obtain connection betw...

BACKGROUND Advanced glycation end products (AGEs) accumulate in patients with end-stage renal disease (ESRD). The aim of this study was to investigate the potential influence of different modalities of renal replacement therapies on plasma AGE levels. METHODS The removal of AGEs by high-flux haemodialysis (HD) using standard and ultrapure dialysis fluid (SDF and UDF), by haemodiafiltration (H...

We use the exceptional depth of the Ultra Deep Field (UDF) and UDFParallel ACS fields to study the sizes of high redshift (z ∼ 2 − 6) galaxies and address long-standing questions about possible biases in the cosmic star formation rate due to surface brightness dimming. Contrasting B, V , and i-dropout samples culled from the deeper data with those obtained from the shallower GOODS fields, we de...

Recommender systems utilize information retrieval and machine learning techniques for filtering information and can predict whether a user would like an unseen item. User similarity measurement plays an important role in collaborative filtering based recommender systems. In order to improve accuracy of traditional user based collaborative filtering techniques under new user cold-start problem a...

The study was aimed at evaluating the antioxidant activity of hydroalcoholic solution extracts of Urtica dioica L. (UD), Malva neglecta Wallr. (MN) plants and their mixture. In this study, flower (UDF), root (UDR), seed (UDS) and leaf (UDL) parts of UD and flower (MNF) and leaf (MNL) parts of MN were used. The antioxidant properties of hydroalcoholic extracts and their mixture were evaluated us...

let denote the unit circle in the complex plane. given a function , one uses t usual (harmonic) poisson kernel for the unit disk to define the poisson integral of , namely . here we consider the biharmonic poisson kernel for the unit disk to define the notion of -integral of a given function ; this associated biharmonic function will be denoted by . we then consider the dilations for and . the ...
