In recent years, the Lamb wave analysis by the multi-channel analysis of surface waves (MASW) for concrete structures has been an effective nondestructive evaluation, such as the condition assessment and dimension identification by the elastic wave velocities and their reflections from boundaries. This study proposes an effective Lamb wave analysis by the practical application of MASW to concre...

We analyze the concrete security provided by a signature scheme described in a recent Internet Draft by McGrew and Curcio.

An unplanned pregnancy is a crisis in a woman's life. She may request assistance from the health care provider in reviewing her options of becoming a parent, continuing the pregnancy and placing her baby for adoption, or terminating the pregnancy. To facilitate the decision-making process for women facing these choices, the clinician must first examine her own values and biases. To aid the clin...

This paper presents an experimental study on circular stirrup-confined concrete specimens under uniaxial and monotonic load. The effects of stirrup volume ratio, stirrup yield strength and concrete strength on damage evolution of stirrup-confined concrete were investigated. The experimental results showed that the strength and ductility of concrete are improved by appropriate arrangement of the...

Concrete piles are a common obstacle in an antilanding field. To research the damage ability of concrete with different shaped charges, penetration tests standoff distances (SODs) were carried out explosively formed projectiles (EFPs) and jetting projectile charges (JPCs). The pressure was measured at positions inside during process, failure mechanism characteristics analyzed. velocity JPC by p...

At present, the lack of both supply and theory in children tourism is due to long-term habit placing opposite or attached state ethics adults, “scenery” eyes haven’t received attention. Therefore, link verify children’s naïve psychology behavior many dimensions substantially, study preference characteristics for types, landscape, recreation destinations other self-constructed causality with beh...
