S2ME2 ANTX brought together industry, academia and the Naval Research and Development Establishment—which includes the Office of Naval Research (ONR) and various research laboratories associated with the Department of the Navy—to demonstrate emerging technology innovations. The exercise involved hundreds of Sailors, Marines and Department of Defense civilian employees and contractors. By using direct feedback and technical evaluations from participating warfighters and senior leadership in attendance, S2ME2 ANTX also may change the way the U.S. Navy and Marine Corps look at prototyping and rapidly acquiring technology. "The large scope of this exercise allows the Navy and Marine Corps to make informed decisions about future generations of technology for use by the warfighter," said Dr. David E. Walker, ONR's director of technology. "This pairing of Sailors and Marines with scientists and technologists will help move innovation at a faster pace." S2ME2 ANTX focused on five capability areas of amphibious operations: ship-to-shore maneuver; weapons fire support and effects; clearing assault lanes; command and control; and information warfare. Demonstrated technologies included unmanned and autonomous vehicles equipped with sensors to gather intelligence in the air, on land and underwater. During each amphibious beach demonstration, unmanned surface and underwater vehicles approached the shore first, collecting intelligence about battlespace conditions—including threats and obstacles—providing an accurate picture of what warfighters would face when leaving their vessels and vehicles. Several ONR- and Naval Research Laboratory-sponsored systems were demonstrated at S2ME2 ANTX, including: Technologies that performed well at S2ME2 ANTX potentially could be featured at Bold Alligator 2017, a multinational series of amphibious exercises led by U.S. Fleet Forces Command and U.S. Marine Corps Forces Command, scheduled for the fall.

Network data analysis helps in capturing node usage behavior. Existing algorithms use reduced feature set to manage high runtime complexity. Ignoring features may increase classification errors. This paper presents a model, allowing classification of network traffic, while considering all the relevant features. Learning phase partitions training sample on values of the respective features. This creates equivalence classes related to m features. During classification, each feature value of the test instance results in picking one set from equivalence class generated during learning. Algorithm captures new behavior in semi-supervised incremental learning mode. For problems having m features and n training samples the model has incremental learning complexity of O(m) and average classification complexity is of the order O(m)log 2n) 2). © de Gruyter 2012.

Sandwich panels made of metal sheets with unfilled cellular cores are found to exhibit lower deflections compared to an equivalent monolithic plate of same metal and similar mass per unit density. The structures having such sandwich panels are suitable under impact loading due to low deflection. However, the process of localized impact on solid structures is quite complicated involving plastic deformation, high strain rates, temperature effect, material erosion, etc. Further, the sandwich panel having triangular corrugated core depends on various design parameters such as thickness of front plate, thickness of back plate, thickness of core, thickness of webs, and angle of web. The influences of these parameters on the structural performance are studied while designing a triangular corrugated core structure for improved ballistic limit for a given mass per unit area. In this research, a numerical analysis of impact of empty triangular corrugated core sandwich panels by ogive nose steel rod projectiles is carried out. Design parameters of the corrugated structure; namely web thickness, core thickness, web angle, front and back plate thickness are varied; and residual velocity of projectile is obtained for each case. Impact at webs resulted in higher projectile retardation and deflection than impact at the base of the prism. For base impacts, improvement in ballistic performance at minimum cost of structural weight can be achieved by increasing web angle or front or back plate thickness, while the same can be achieved for web impacts by increasing web thickness. Since web impacts experience higher penetration resistance than base impacts, designing the panel using optimum design parameters for web impacts is desirable. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav
