Underwater acoustic channels are naturally sparse, but how to effectively exploit the sparsity is a challenging task. ...http://www.ntis.gov/search/product.aspx?ABBR=ADA571794A method of determining the bit error rate (BER) of a digital circuit from the measurement of the analog S-parameters of the circuit has been developed. The method is based on the measurement of the noise and the standard deviation of the noise in th ...http://www.ntis.gov/search/product.aspx?ABBR=N20120016799We conducted this review to determine the merits of an allegation that VA was transmitting sensitive data, including Personally Identifiable Information (PII) and internal network routing information, over unencrypted telecommunications carrier netwo ...http://www.ntis.gov/search/product.aspx?ABBR=PB2013107375Today s defense environment is particularly challenging for two reasons. First, significant portions of the force are continuously engaged in a variety of operations, ranging from active combat to humanitarian assistance, over wide geographical areas ...http://www.ntis.gov/search/product.aspx?ABBR=ADA571950Researchers developed a software system called CrashHelp to improve the information exchange from emergency medical services (EMS) practitioners to emergency room/trauma center providers. The system combines mobile smartphone, multimedia, Web server, ...http://www.ntis.gov/search/product.aspx?ABBR=PB2013106572The Western Electric Company produced a multi-line telephone during the 1940s-1970s using a six-button interface design that provided robust tactile, haptic and auditory cues regarding the state of the communication system. This multi-line telephone ...http://www.ntis.gov/search/product.aspx?ABBR=N20120016965The project started on 04/01/10, and the reporting period covers from 09/01/10 to 08/31/11. The main objective for this period was to gain deep insight on the propagation phenomena that most affect underwater acoustic systems, based on the experiment ...http://www.ntis.gov/search/product.aspx?ABBR=ADA571822This proposed research seeks to identify, explain, and ultimately predict, the factors that significantly alter the operational effectiveness of underwater acoustic communications through experimental work and theoretical analysis. The long-term goal ...http://www.ntis.gov/search/product.aspx?ABBR=ADA571788Direct-writing offers serial or point deposition for the fabrication of two-dimensional linear elements or patterns. A common use for direct write technologies in two-dimensions is the fabrication of sensors, antennas and other conductive circuitry. ...http://www.ntis.gov/search/product.aspx?ABBR=ADA571899This paper describes the design and initial positive evaluation of a prototype adaptive automation system to create an enhanced command and control (C2) infrastructure for more effective operation of unmanned vehicles. Our main project objective is t ...http://www.ntis.gov/search/product.aspx?ABBR=ADA571805The Theater Battle Management Core System (TBMCS) is an integrated air command and control (C2) system that performs standardized, secure, automated air battle planning and execution management for Air Force, multi-service, and allied commanders in t ...http://www.ntis.gov/search/product.aspx?ABBR=ADA572204
