Spelling correction can assist individuals to input text data with machine using written language to obtain relevant information efficiently and effectively in. By referring to relevant applications such as web search, writing systems, recommend systems, document mining, typos checking before printing is very close to spelling correction. Individuals can(More)
The heart is an extremely sophisticated organ with nanoscale anisotropic structure, contractility and electro-conductivity; however, few studies have addressed the influence of cardiac anisotropy on cell transplantation for myocardial repair. Here, we hypothesized that a graft's anisotropy of myofiber orientation determines the mechano-electrical(More)
Biodegradable nanofibrous membrane was prepared from poly-L-lactic acid by electrospinning and used as a scaffold for cartilage tissue engineering. Operating parameters during the electrospinning process were studied in terms of their influences on fiber diameter, membrane porosity and pore size. In order to improve cell attachment and growth, nanofibrous(More)
To avoid the confusion of phonetic acoustic models between different languages is one of the most challenges in multilingual speech recognition. We proposed the method based on Latent Dirichlet Allocation to avoid the confusion of phonetic acoustic models between different languages. We split phonetic acoustic models based on tri-phone. And merging the(More)
Electrospinning is the novel process to produce fibrous membranes with nanoscale diameters and properties of high specific surface area as well as porous structure, so electrospun nanofibrous membrane are excellent support for filtration, drug delivery, tissue engineering scaffold and enzyme immobilization. In this study, nanofibrous membrane, made by poly(More)
In recent years, Orthogonal Frequency Division Multiplexing (OFDM) technology has been widely used in many wireless communication systems, including LTE and WiMAX. Bandwidth is always precious over wireless channel, so it is important to have an effective bandwidth arrangement. On a multi-user system, each user needs to share entire bandwidth with others.(More)
Based on the relationship between district GDP and sewage disposal, the water environment protection effect in 3 cities, Suzhou, Nanjing and Xuzhou, with different economic development degrees in Jiangsu Province was dynamically analyzed. The economy in Suzhou was well developed, where the foreign capital proportion was in a high level. Its GDP per capita(More)
