The spatial variation in vector acoustic intensity has been calculated between 100 and 3000 Hz near a high-performance military aircraft. With one engine of a tethered F-22A Raptor operating at military power, a tetrahedral intensity probe was moved to 27 locations in the geometric near and mid-fields to obtain the frequency-dependent intensity vector field. The angles of the maximum intensity ...

A 1985 graduate of the Coast Guard Academy, Captain Watts has served six sea tours with the Navy and Coast Guard, most recently commanding USCGC Steadfast (WMEC 623). A qualified Surface Warfare Officer and Cutterman, he holds advanced degrees from the Naval War College, Old Dominion University, American Military University, and the Naval Postgraduate School, and he is currently a doctoral cand...

For over fifty years, factual information on a wealth of details concerning Russian military materiel and systems was successfully obscured behind a tight blanket of state-imposed security. Attributable to polar economic philosophies characterising the clash between America‟s system of capitalistic democracy and the Soviet Union's form of state-sponsored (Communist) socialism (during the culmin...

Wireless sensor network (WSN) is an emerging technology that shows great promise for various applications both for mass public and military. The sensing technology combined with processing power and wireless communication makes it lucrative for being exploited in abundance in future. In many important military and commercial applications, it is critical to protect a sensor network from maliciou...

Accurate and stable frequency reference sources are critical for commercial, navigation, military, and scientific space applications. Each piece of flight hardware has requirement-types that are generic such as size, weight, power, and reliability, and requirement-types that are specific to the hardware function. The key requirement-types for frequency reference sources are phase noise and stab...

Rapid advances in consumer electronics have led to the anomaly that consumer gaming hardware and software now provide better interactive three-dimensional graphics than military and other specialized systems costing orders of magnitude more. UTSAF is bridging software written to take advantage of the power of modern gaming systems by allowing them to participate in distributed simulations with ...

A history of architectural and process advancements has enabled Altera® Cyclone® V FPGAs to be used in numerous low-cost and low-power applications in the industrial, automotive, military, communication and consumer markets, among others. This white paper outlines a real-life PCI Express® (PCIe®) Gen1x4 reference design including a DDR3 memory controller. It shows just how effective Cyclone V F...
