We present a proof-of-principle study about the use of a sensor for the nondestructive monitoring of strength development in hydrating concrete.The nondestructive evaluation technique is based on the propagation of highly nonlinear solitary waves (HNSWs), which are non-dispersive mechanical waves that can form and travel in highly nonlinear systems
Massive device-to-device communication nodes and Internet of Things (IoT) devices are expected to be crucial components in next-generation wireless networks.However, the energy constraint of these nodes presents a challenge since the energy of the batteries is limited.Motivated by this, radio frequency energy harvesting (EH) has been developed as a
Obsessive-compulsive disorder and major depression are common etiologies that they are not well defined for the association of these disorders, especially in aging.The purpose of this research was the Comparison of anxiety sensitivity, perfectionism, loneliness and self-esteem of patients with obsessive-compulsive disorder and major depression.The
Extension of rural tourism industry is one of the options which nowadays have made the policy makers, programmers Pulse Sensor Set and executers of investment for rural development think about due to the expansion of city dwellings and urban environmental pollution.As an important and basic industry in economic and culture sections, it can play an
