Abstract In order to cope with the continuous progress of tank protection technology, it is imperative optimize and improve ability existing armor-breaking warheads. This paper mainly introduces development history explosive reactive armor, shaped charge jet formation theory, penetration warhead series technology research status armor-breaking/killing compound technology. Finally, trend in futu...

Steep topography on the ocean bottom, when underneath an oscillating tide, is not only associated with significant internal wave generation at the tidal frequency but also nonlinear flow features, large overturns and turbulent flow. Here, we investigate the internal wave dynamics and turbulence at an isolated steep obstacle using a three-dimensional, high-resolution large eddy simulation (LES)....

Axisymmetric standing waves occur across a wide range of free surface flows. When these reach critical height (steepness), wave breaking and jet formation occur. For travelling gravity waves, is generally considered to limit reversible motion. In the ocean, behaviour directionally spread lies between limits purely (two dimensions) axisymmetric (three dimensions). Hence, understanding on an impo...

The atmospheric circulation over the North Atlantic–European sector experienced exceptional but highly contrasting conditions in the recent 2010 and 2012 winters (November–March, with the year dated by the relevant January). Evidence is given for the remarkably different locations of the eddy-driven westerly jet over theNorthAtlantic. In the 2010 winter themaximumof the jet streamwas systematic...

A key aim of the Large Hadron Collider (LHC) is to discover the Higgs boson, or to prove its non-existence, and hence elucidate the mechanism of mass generation and electroweak symmetry breaking. Current electroweak fits, together with the LEP exclusion limit, favour a light Higgs boson, i.e. one around 120 GeV in mass [1]. This mass region is particularly challenging for the LHC experiments, a...

We explore the potential of the CERN Large Hadron Collider to access a strongly interacting electroweak symmetry breaking sector via weak boson scattering with W+W−jj, ZZjj and WZjj final states. As examples of models with scalar or vector resonances we concentrate on a scenario with a heavy Higgs boson and on a Warped Higgsless Kaluza-Klein model of narrow spin-one resonances. The signal and t...

Whether gamma-ray bursts are highly beamed or not is a very important question, since it has been pointed out that the beaming will lead to a sharp break in the afterglow light curves during the ultra-relativistic phase, with the breaking point determined by Γ ∼ 1/θ 0 , where Γ is the bulk Lorentz factor and θ 0 is the initial half opening angle of the ejecta, and such a break is claimed to be ...
