BACKGROUND Unlike hemorrhagic injuries in which direct pressure is indicated, any pressure placed on the eye after penetrating trauma can significantly worsen the injury by expulsing intraocular contents. The accepted first response measure for obvious or suspected penetrating ocular injury is placement of a rigid shield that vaults the eye so as to prevent accidental iatrogenic aggravation dur...

The purpose of this paper is to propose a solu tion methodology for a missile defense problem involving the sequential allocation of defensive resources over a series of engagements The problem is cast as a dynamic program ming Markovian decision problem which is computation ally intractable by exact methods because of its large num ber of states and its complex modeling issues We have em ploye...

Current Army C2 systems cannot integrate “come as you are” capabilities into operations making it difficult to combine participants into a cohesive force. This paper describes the Agile Planner concept developed by BAEAIT as robust approach for configurable C2 “on the fly”. With an Agile Planner, participants declare their capabilities when they register into the system. Once they do so, an Agi...

We have developed a methodology for using a normatively correct task model as the basis for a training methodology and for the provision of performance feedback within a national missile defense (NMD) simulated task environment (STE). This methodology has allowed us to explore: 1) the relative impact of expert versus optimal feedback, 2) the differences in task performance among an optimal mode...

the 56th pugwash conference on science and world affairs opened with a key note address by the italian minister of foreign affairs, massimo d’alema, and the un secretary-general ban ki-moon’s message in bari, italy, on 21 october 2008. in the week-long meeting, the participants discussed a wide array of topics related to regional security issues such as the status of nuclear arms control, the r...

Abstract This paper takes the 35mm armor-piercing projectile as research object, and uses ANSYS LS-DYNA dynamic analysis platform to simulate process of penetrating armored steel plate under different rotation speeds by using Johnson-Cook constitutive model. The results show that speed has a certain influence on penetration performance projectile: will have effects contact stress target in late...

Abstract With the increasingly complex combat environment and diversity of tasks, important military targets are surrounded by multi-layer defense. Modern information warfare pays more attention to system confrontation multi-system cooperative operations,and missile formation attack is main research content this paper. For wing ideal trajectory generation problems, ensure Angle time meet design...

The United States counts South Korea as one of its most significant allies. Relations between the two countries began when US and became military allies in early 1950s, with promising to assist defending itself against any North Korean assault. Since 2014, has attempted include East Asia region's anti-missile defense system, but it always been refused. There are several causes for this, includi...
