    摘要： A piezoelectric fiber composite and a magnetoelectric laminate composite including the same are disclosed. The piezoelectric fiber composite includes a first protective layer having a first electrode, a second protective layer having a second electrode, and a piezoelectric fiber layer formed between the first and the second electrode and having piezoelectric fibers arranged in the longitudinal direction of the composite, wherein the piezoelectric fibers include a single-crystal piezoelectric material and are configured such that a direction of the single crystal is identical to a thickness direction of the composite and a direction of the single crystal is identical to a longitudinal direction of the composite, thus exhibiting superior piezoelectric strain properties and sensing properties. Also, the magnetoelectric laminate composite includes the piezoelectric fiber composite and a magnetostrictive layer including a magnetostrictive material such as nickel (Ni) or Metglas (FeBSi alloy), thus ensuring significantly improved magnetoelectric properties.

    摘要： Methods and systems for sending multicast messages are disclosed. A multicast message is received to be transmitted to a plurality of access terminals at a radio access network (RAN), the received multicast message having a first format. The first format may correspond to a conventional multicast message format. The RAN determines whether the received multicast message requires special handling. If the RAN determines the received multicast message requires special handling, the radio access network converts the received multicast message from the first format into a second format. The RAN transmits the converted multicast message with the second format (e.g., a data over signaling (DOS) message) on a control channel to at least one of the plurality of access terminals. The access terminals receiving the converted multicast message interpret the message as a multicast message.

    摘要： The invention relates to an assembly for nondestructive material testing, by means of which assembly shear waves are emitted into elastic surfaces of components or workpieces and detected, wherein piezoelectric transducer elements are arranged one over the other in a plurality of planes and the piezoelectric transducer elements that are arranged in adjacent planes are operated oppositely to each other. The piezoelectric transducer elements can be piezoelectric fibers and/or piezoelectric plate-shaped elements, which are connected to or embedded in an elastically deformable material.
