The soldier is the Army’s most deployed combat system and the most essential weapon in the Army’s arsenal. Program Executive Office (PEO) soldier was activated in October 2001 to equip the soldier as a system through centralized development, acquisition, fielding and sustainment of virtually everything the soldier wears or carries. The mission of PEO Soldier is to ensure that soldiers are letha...

The present study compared the performance of soldier pile and concrete bearing pad anchored wall facings. Using Abaqus finite element software, two case studies have been precisely represented for the facing designs and effects of the parameters of soil type, spacing of anchors and facings, surcharge and facing sizes were investigated. The analysis results indicate that the soldier pile method...

Soldier Station is a unique simulation system which bridges the gap between two distinct realms of modeling: constructive and virtual. The Soldier Station operator controls a simulated dismounted infantry soldier in a 3D virtual environment with rules of movement, engagement and tactics provided from a constructive model. This paper describes the Soldier Station system, its design, and the inte...

The use of audio sensors for soldier systems is examined in detail. We propose two applications, speech recognition and speaker veri cation. These technologies provide two functions for a soldier system. First, the soldier has hands-free operation of his system via voice command and control. Second, identity can be veri ed for the soldier to maintain the security integrity of the soldier system...

The role of the Soldier is not as strictly defined today, as it was in World War II. In place of battlefields, the Soldier is placed in roles from peace keeper to combat Soldier in collapsed first world counties to impoverished third world nations. This fogs the understanding of situations and the role the Soldier is to play in them. Within these changing and dynamic times, a Soldier’s situatio...

Caste evolution is a central process in the adaptive diversification of insect superorganisms. Nevertheless, how ecology shapes adaptive caste evolution remains poorly understood. Recent work with the ant genus Cephalotes has provided new comparative evidence that ecological specialization may drive adaptive caste specialization. Here, three key predictions of this adaptive hypothesis are suppo...

1. Defensive individuals, termed soldiers, have recently been discovered in aphids, Soldiers are typically early instar larvae, and in many species the soldiers are reproductively sterile and morphologically and behaviourally specialized. 2. Since aphids reproduce parthenogenetically, we might expect soldier production to be more widespread in aphids than it is. We suggest that a more useful wa...

In termites the evolution of reproductive altruism is not based on a particularly high relatedness between nestmates. For the evolution and maintenance of the ancestral sterile soldier caste, the benefits generated by the soldiers' presence must compensate the loss of the soldiers' reproductive potential. To study the impact of soldiers on colony's fitness, we manipulated the proportion of sold...
