North Korea’s strategic weapons innovation system is exemplary of an authoritarian mobilization model. The top leadership prioritizes the program and mobilizes country’s science, technology, heavy industrial resources around key programs. Key to success are investments in a defense infrastructure that runs from basic research development applied R&D, product development, linked production capab...
This paper examines the impact of hypersonic threat on evolution U.S. missile defense. The article analyzes specifics this threat, related doctrinal and practical changes, describes characterizes planned defense architecture, forecasts prospects for its implementation strategic situation. author comes to a conclusion that – counter-hypersonic capabilities are aimed at countering posed by interm...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
The article provides an analysis of the state affairs in field U.S. missile defense, inherited by Biden administration from previous administration. U. S. defense policy can be roughly divided into three components: homeland regional and advanced developments related to these both parts. Conclusions are made about prospects policy, taking account such factors as views experts think tanks close ...
Abstract In modern warfare, precision guided munitions have become one of the major equipment to attack and hit enemy’s crucial value targets. addition, they are critical targets missile defense anti-aircraft interceptor system varying countries during interception destruction, world has increased investment in defense. Therefore, penetration countermeasures capacities missiles holds key victor...
the community dynamics of aquatic coleoptera(insecta)in one of the spring-stream habitats of bammo national park in fars province called cheshmeh-ye-ghanbari is studied as a pilot project and model for acquaintance with and furthering the biodiversity studies on fauna of iran. sixteen species-populations out of nineteen of this community were already identified for their taxonomy and for thei...
asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
Two recent developments in South Asia have increased the risk of an accelerated arms race between India and Pakistan. One development is PakistanÕs introduction of theNasrmissile, a very-short-range, ÒtacticalÓ nuclear weapon that threatens IndiaÕs conventional forces and could also tempt other countries to develop battlefieldusable nuclear weapons. The other development is IndiaÕs announcement...
High-level networking model and technology suitable for effective management of large distributed dynamic air and missile defense systems will be described which can cope with different kinds of unpredictable and asymmetric situations including massive air and missile attacks. Using this Spatial Grasp Technology (SGT), intelligent distributed command and control infrastructures, as demonstrated...
