The paper takes a type of flexible air bearing as the research object, and structure is analyzed in detail. Combined with traditional analysis method tilting pad fluid-solid coupling theory, new model for performance prediction was established. inner diameter 70mm calculated by changing input pressure or inlet capillary diameter. optimized analyzing calculation results, separate nozzle added. A...

It is reported in this article that Si nanowires can be employed as a positive template for the controllable electrochemical deposition of noble metal tube. The deposited tube exhibits good crystallinity. Scanning electron microscope and transmission electron microscope characterizations are conducted to reveal the growth process of metal tube, showing that the metal tube grows quasi-radially o...

An instrument made by ourselves was used to fabricate biodegradable chitosan-heparin artificial vascular prosthesis with small internal diameter (2 mm) and different crosslinking degree from biodegradable chitosan, chitosan derivates and heparin. In vivo and in vitro degradation studies, inflammatory analysis and electron microscope scanning of this artificial vascular prosthesis were performed...

This paper examines the effect of the water sprays commonly used to cool freshly drawn glass fibers. A model has been developed using a Karman-Pohlhausen treatment of the velocity and thermal boundary layers and accounting for the evaporation of an entrained water spray. Solutions of the model equations have been calculated, and the effect of changing various process parameters is studied. Vari...

The Quality of Service (QoS) mapping in Internet Protocol (IP) based networks is not well-suited for complex multimedia services in a dynamically changing service environment and service adaptation driven by such changes. The work presented in this paper is motivated by the challenge to utilize additional knowledge about the service and its adaptation capabilities, in form of the Media Degradat...

In this paper, we first present a new variation of hypercubes, denoted by SQn. SQn is obtained from Qn by changing some links. SQn is also an n-regular n-connected graph but of diameter about n/4. Then, we present a generalization of SQn. For any positive integer g, we can construct an n-dimensional generalized shuffle-cube with 2n vertices which is n-regular and n-connected. However its diamet...

This paper addresses the topic of online unsupervised speaker segmentation in a complex audio environment as it is present in the Broadcast News databases. A new two stage speaker change detection algorithm is proposed, which combines the Bayesian Information Criterion with an ABLS-SCD statistical framework where adapted Gaussian mixture models are used to achieve higher accuracy. To enhance th...

Differential Ks-band luminosity functions (LFs) are presented for a complete sample of 1613 nearby bright galaxies segregated by visible morphology. The LF for late-type spirals follows a power law that rises towards low luminosities whereas the LFs for ellipticals, lenticulars and bulge-dominated spirals are peaked and decline toward both higher and lower luminosities. Each morphological type ...
