Successful submarine operations—those that accomplish the mission while maintaining security and safety—depend on numerous factors, including the capabilities of various sensor systems, the reliability of algorithms, and the proficiency of the crew. Among the most critical elements is Command Team decision-making and the underlying processes that create a cohesive and effective team. As a team,...

Thedesignanduseof a new device for increasing low level Alpha counting efficiency of the standard AN/PDR-56 Alpha Particle Meter is described. Directions for its construction, list of materials required, photographs and diagrams are furnished. The practical application of shipboard utilization of such a device is pointed out. ADMINISTRATIVE INFORMATION This report was completed in partial fulfi...

The capacity of the global communications network is being progressively increased to handle the rapid growth in telecommunication traffic generated by the Internet. Fujitsu supplies submarine optical cable systems that can provide the huge capacity and short transmission delay required by carriers. There are two ways to increase capacity: construct a new submarine cable system or upgrade the e...

Control biochemical and hematologic data were gathered for 1017 healthy submariners who ranged in age from 19.5 to 43.5 years. Means, standard deviation, and frequency distribution are presented for 24 whole blood and serum variables and, where appropriate, for 11 urinary variables. After statistical separation of the effects of aging and length of submarine service, it has been determined that...

background economic consequence analysis is vital for recognizing pipeline comprehensive risk analysis and emergency response planning. objectives the purpose of this study was to estimate economic loss due to fire and explosion in petrochemical feed and product pipelines. materials and methods the present study which performed on 47 pipelines of a petrochemical special zone, pertinent pipeline...

Received Nov 30, 2017 Revised Feb 8, 2018 Accepted Feb 25, 2018 Submarine Wireless Sensor Networks (SWSNs) have earned important concentration of both university and manufacturing in current years. In this paper, we introduce intensity and trustworthiness awake delay perspective (ITADP) routing protocol for submarine WSNs. We get inspiration from Submarine Opportunistic Routing (SOR) protocol t...

Based on the ICD (Individual channel Design) approach, the design of a multivariable digital submarine depth control system is presented. The model of the submarine is the standard 80 meters British submarine. As expected, the frequency rate of sampling introduces limitations to achieve the required responses. Furthermore, the discrete model presents zeros close to imaginary axis resulting in a...

Dynamic change at the marine-terminating margins of the Greenland Ice Sheet may be initiated by the ocean, particularly where subglacial runoff drives vigorous ice-marginal plumes and rapid submarine melting. Here we model submarine melt-driven undercutting of tidewater glacier termini, simulating a process which is key to understanding ice-ocean coupling. Where runoff emerges from broad subgla...
