Background: To explore the strengths and weaknesses of conventional biomedical research strategies and methods as applied to complementary and alternative medicine (CAM), and to suggest a new research framework for assessing these treatment modalities. Discussion: There appears to be a gap between published studies showing little or no efficacy of CAM, and reports of substantial clinical benefi...

This investigation addresses a nonlinear terminal guidance/autopilot controller with pulse-type control inputs for intercepting a theater ballistic missile in the exoatmospheric region. Appropriate initial conditions on the terminal phase are assumed to apply after the end of the midcourse operation. Accordingly, the terminal controller seeks to minimize the distance between the commanded missi...

Missile design is often separated into distinct subsystems such as seeker stabilization, target detection and tracking, guidance, and autopilot. The miss distance strongly depends on proper integration of those critical subsystems and the prototyping of visually guided missiles. A low-cost integrated solution based on a PC running Matlab is an attractive option to test new ideas on guidance, co...

This paper presents a special underwater robot for subsea pipelines inspection which is used to transport extracted oil and gas from oil platforms to onshore facilities. Due to the high pressure in the deep sea and the long pipelines, it is impossible to inspection by divers. Therefore underwater robot can be used to solve this problem. This paper investigate a hovering type of underwater vehic...

2 INTRODUCTION The guided missile provides military forces with the capability to deliver munitions rapidly and precisely to selected targets at a distance. This capability establishes an effective means to conduct a wide variety of military missions that range from denying the enemy communications or supply routes, to establishing air superiority, to performing anti-ship cruise missile or ball...

The campaign of opposition to MX missile deployment in the Great Basin of Nevada and Utah stands as a unique case of grassroots mobilization, because it took place in a region whose inhabitants both supported a strong U.S. military defense posture and considered the decision-making processes of foreign policy and national security remote to their overall concerns. This study holds that the two ...

An inspection of signal processing approach in order to estimate underwater network cardinalities is conducted in this research. A matter of key prominence for underwater network is its cardinality estimation as the number of active cardinalities varies several times due to numerous natural and artificial reasons due to harsh underwater circumstances. So, a proper estimation technique is mandat...

Apparent design breakthroughs in short-range missile defense systems such as Theater High-Altitude Air Defense (THAAD) have prompted questions about the legality of such systems under the 1972 Antiballistic Missile (ABM) Treaty. Prominent physicists have used computer “footprint” methodology to prove that if engineered to specifications, THAAD might exceed ABM Treaty performance limits banning ...
