    摘要: A capacitive micromachined ultrasound transducer (cMUT) comprises a lower electrode. Furthermore, the cMUT includes a diaphragm disposed adjacent to the lower electrode such that a gap having a first gap width is formed between the diaphragm and the lower electrode. Additionally, the cMUT includes at least one element formed in the gap, where the at least one element is arranged to provide a second gap width between the diaphragm and the lower electrode.

    摘要: A method for determining location of a target within an indoor environment, including the steps of: classifying a set of anchors having known locations within the indoor environment and a set of targets having unknown locations within the indoor environment, wherein each of the anchors and targets comprise hardware having sensors and wireless communication capabilities; creating a set of ordinal pair data sets comprising relative distances between each target and all anchors; ranking and aggregating the ordinal pair data sets to produce a set of dissimilarities that approximate distances; transforming the dissimilarities into estimated distances between each anchor and target using the known distances between the anchors as calibration; and inferring location of targets by formulating and solving a multidimensional unfolding optimization.

    摘要: The invention relates to a carbon nanoring and a method for preparing the same. The carbon nanoring according to the present invention is composed of monolayered or multilayered coaxial carbon rings, wherein the carbon ring has a structure similar to that of a closed ring system formed by graphite sheet being rolled, and each of an axial dimension and a radial dimension of the carbon nanoring is nanoscale with the axial dimension being smaller than the radial dimension. The invention further provides a method for preparing the above carbon nanoring including calcinating in an inert atmosphere or a reducing atmosphere a layered double hydroxides obtained by intercalating a long-chain alkyl anion and a carbon source molecule, growing a carbon nanoring within a confined region between layers under the catalysis of the metal element in layers, and removing the metal and the metal oxide by dissolving in an acid to obtain the carbon nanoring. By using this method, the carbon nanoring can be effectively controlled in terms of the axial dimension, the radial dimension, and the number of layers of the carbon ring thereof. The carbon nanoring provided by the present invention has the nano-ring shaped structure and the excellent properties of carbon materials, as well as more edge carbons and dangling bonds, and thus it has broad application prospects in such field as nanodevices, energy storage and sensing.
