Public opinion analysis for micro-blog post is a new trend, and wherein emotional tendency analysis on micro-blog topic is a hot spot in the sentiment analysis. According to the characteristics of contents and the various relations of Chinese micro-blog post, we construct the dictionaries of sentiment words, internet slang and emoticons respectively, and then implement the sentiment analysis al...

There have been many domain-specific keyword extraction researches, but micro-blogoriented keyword extraction is just beginning. This paper researches into the keyword extraction from Chinese micro-blog. Taking the characteristics of micro-blog into account, such as short, topic divergence, etc., we propose a Chinese micro-blog keyword extraction method based on the combination of multi feature...

hydropower plant and especially micro-hydropower plant is an available, reliable and economical energy source. micro-hydropower plant is one of the most environment-friendly technology, use and development of which leads to reduction of energy consumption sporadically and worldwide. along with the growth of these power plants, the issues related to the control of electrical parameters such as l...

Micro-gap formation at the implant-abutment interface of two-piece dental implants was investigated in vitro using high-resolution radiography in combination with hard X-ray synchrotron radiation. Images were taken with the specimen under different mechanical loads of up to 100 N. The aim of this investigation was to prove the existence of micro-gaps for implants with conical connections as wel...

Ultrasound wave is a kind of waves with the frequency higher than the human audible frequency. Although ultrasound was first used for military identification purposes, it has been used for decades for various other applications, especially medical applications. Medical applications of ultrasound include diagnostic and therapeutic applications, such as for the treatment of cancer. In this paper,...

In the manufacturing of micro/nanocomposite materials, micro/nanoparticles need to be dispersed evenly into the base materials. However, due to their high surface-to-volume ratio and high surface energy, the micro/nanoparticles tend to agglomerate and cluster together. Ultrasonic cavitation is effective to disperse micro/nanoparticles. However, works on correlating the cavitation parameters wit...

INTRODUCTION Micro Electro Mechanical Systems (MEMS) based micro-positioning stages are critically important in many micro/nano manipulation and manufacturing applications. Such stages have been extensively used in micro-force sensors, scanning probe microscopy and micro optical lens scanners [1-4]. While there is no unique definition for a micro-positioning stage, it generally refers to a syst...

Recent advances in the field of silicon micro-fabrication techniques and silicon-based Microelectromechanical Systems (MEMS) have led to the possibility of a new generation of micro heat engines for power generation and micro air-vehicle propulsion applications. The design for a silicon-based, micro gas turbine generator capable of producing 10-50 Watts of power in a volume less than 1 cm3 whil...
