Several major improvement techniques in link selection, load and energy balance are analyzed??Cand a new routing technique for balancing the load and energy in the network is Proposed. In this technique, the nodes are divided into several different states according to state of itself, and then the node response the routing requests in different ways on the basis of node states. By NS 2 simulation...
Mechanical properties of lung are closely related to lung diseases. However, currently there are no noninvasive methods that can measure the local lung tissue mechanical properties. In this paper, a technique that involves tracking the surface wave propagation and using ultrasound images to guide the measurements is introduced. The proposed method is tested on a human subject at both functional residual...
Surface wave speed is measured in a two-layer gelatin phantom in water on three different surfaces with a scanning ultrasound transducer. The gelatin concentrations of the two layers of the phantom are 15% and 10% and the three surfaces are the two outside surfaces of the 15% and 10% layers and the interface between the two. The speed measured on the outside surface of the 15% layer is faster than...
