Process industries often use B-ring self-tightening sealing structures and rely on interference assembly to meet the initial requirements. Therefore, determining reasonable material, size is crucial ensure performance of structure. In this paper, based elastic deformation analysis, co-ordination equation a structure was established, contact pressure calculation formula obtained, with discussion...

Experiments in NSTX have now demonstrated the coupling of toroidal plasmas produced by the technique of Coaxial Helicity Injection (CHI) to inductive sustainment and ramp-up of the toroidal plasma current. In these discharges, the central Ohmic transformer was used to apply an inductive loop voltage to discharges with a toroidal current of about 100 kA created by CHI. The coupled discharges hav...

We find that VC-backed firms receiving their initial investment in hot markets are less likely to IPO, but conditional on going public are valued higher on the day of their IPO, have more patents and have more citations to their patents. Our results suggest that VCs invest in riskier and more innovative startups in hot markets (rather than just worse firms). This is true even for the most exper...

The cost eeective ABR service is suitable for transmitting bursty compressed video over ATM network. Here, we propose a Fast Buuer Fillup (FBF) scheme to run VoD over ATM network with ABR service. We develop models to determine buuer size at the client and the server for our scheme. We also develop relationships between the startup delay, the ABR service parameters, and the network congestion s...
