In this paper, a new method for designing an active dual-band dipole antenna is proposed. The operating frequencies of the proposed antenna are 150 and 450 MHz that are usually used in military applications. Using a series stub is the main idea in the proposed dual-band antenna, where it makes an independent resonance frequency higher than the main resonance frequency of a conventional dipole. ...

In Wireless Sensor Network (WSN) applications it is critical to accurately determine the location of the distributed sensor nodes in order to report the data that is geographically meaningful. Since localization and tracking algorithms have been attracting research and development attention recently, a wide range of existing approaches regarding this topic have emerged. Tracking and localizatio...

BACKGROUND Although there are no established biomarkers for posttraumatic stress disorder (PTSD) as yet, biological investigations of PTSD have made progress identifying the pathophysiology of PTSD. Given the biological and clinical complexity of PTSD, it is increasingly unlikely that a single biomarker of disease will be identified. Rather, investigations will more likely identify different bi...

The Military is embracing the communication revolution, turning to a new generation of sophisticated systems to enable faster, richer, less costly, more flexible, reliable, compact, mobile, jam resistant, low probability of detection, re configurable and spectrally efficient communication. Many of these features can be added to a great extent in the existing systems, by utilising MIMO technolog...

Five experiments were conducted to study the acoustic attributes that enable the accurate identification and localization of rudimentary spatial warning sounds. In each experiment, two sounds were played simultaneously over loudspeakers at various azimuths and elevations. The stimuli consisted of pure tone complexes with a 13 kHz bandwidth. The fundamental frequencies, the amplitude modulation ...

The G-12 Solid State Device Committee of the Government Electronics & Information Technology Association (GEIA) developed guidelines for assessing the suitability of plastic encapsulated microcircuits and semiconductors for use in military, aerospace and other rugged applications. EIA Engineering Bulletin SSB-1, Guidelines for Using Plastic Encapsulated Microcircuits and Semiconductors in Milit...

Mobile agents compete with multicasting for applications in distributed military systems. Systems such as unmanned aerial vehicles (UAVS) and automatic target recognition (AiTR) devices utilize intelligent agents to sense the environment and make decisions regarding reporting or firing on a target. Mobile agents migrate between these distributed components and assist in the learning and deducti...

The United States military is continuing to research and is beginning to employ OWL-related information representation technologies. The Joint Explosive Ordnance Disposal (JEOD) Decision Support System (DSS) is using OWL to present relevant procedural information to warfighters. The United States Air Force (USAF) is experimenting with representing portions of the Foreign Clearance Guide (FCG) i...
