Arranging microparticles into desired pattern is of particular importance for many applications in the field of micro-electronics-mechanical system, regenerative medicine, tissue engineering and composite fabricating. A variety of techniques for patterning microparticles on the substrate have been developed in recent years based on optic, magnetic and electric field. However, each above mentioned...
In this paper, we present a sound field synthesis technique based on the mode-matching and inverse-filtering to manipulate micro-particles within a given region. The technique employs a set of PZT transducers evenly placed on the perimeter of a 50 mm-radius circle to generate and manipulate the desired local ultrasonic filed. Adjusting the parameters of driven signals applied to the transducer array...
In this paper, a new prototype of magnetostrictive-based vibration energy harvester for power generating floor systems is presented, and its structure is constructed. The harvester utilizing the Villari effect (inverse-magnetostrictive effect) consists of a coil-wound Terfenol-D rod. To generate more electrical power, a PM (fixed on the part of cap amplifier) and variable-length air-gap are designed...
This Paper presents the conceptual design of a self-sensing actuator (SSA) based on giant magnetostrictive material, which consists of variable-air-gap with a displacement amplification mechanism. A driving solenoid coil, surrounds the GMM rod, used to sense changes of magnetic induction in GMM. Modeling and simulation are used to validate the concept. Sensing relation is derived, uniformity and intensity...
A bibliometric analysis was applied in this work to compare SCI and EI papers on GIS. The published output analysis showed that GIS research has steadily increased in both databases of SCI and EI. The different characteristics of SCI and EI databases in journals and keywords were also discovered. It showed that we should select proper database according to the characteristics of different research...
A bibliometric analysis was applied in this work to evaluate global scientific production of data mining papers of the science citation index (SCI), which was compiled by Institute for Scientific Information (ISI), Philadelphia, USA. The published output analysis showed that data mining research steadily increased over the past 20 years and the annual paper production in 2007 was about three times...
This paper proposes a new method for document categorization, based on support vector machine (SVM) using a concept vector model (CVM). The traditional document classification usually ignores the semantic relations among the keywords or documents. To effectively solve the semantic problem, the domain ontology is used to capture the semantic information among different terms or keywords in the documents...
Hits algorithm has gotten great success and been applied in the analysis of Web linking. Hits algorithm is used to search the authority pages and the hub pages from the results of the search engine, and it can also be used to search the Web communities. But Hits algorithm is based on the hyperlinks of the pages, it is easy to bring the problem of topic excursion. Hits algorithm requires a number of...
Many Web information retrieval methods are related to special Web sites, for example, the method based on extracting rules and the one based on training page samples. These methods can do well in a Web site but fail in the others without adding new rules or inputting new training pages manually. Furthermore, if the template of the Web site is changed, it has to redesign the extracting rules or re-inputting...
