ductance of layer. These dependencies showed that hybridization appears when sheet conductance of layer (σ) exceeds some critical value σcr), the magnitude of which changes in wide range and depends on material and plate orientation. For example, for aforementioned hybrid pair A0 SH0 in potassium niobate σcr = 10−3S. If σ < σcr modes are not coupled, i.e. their dispersion curves do not repulse....
متن کاملSession Initiation Protocol (sip) Session Mobility Draft-shacham-sipping-session-mobility-05
Session mobility is the transfer of media of an ongoing communication session from one device to another. This document describes the basic approaches and shows the signaling and media flow examples for providing this service using the Session Initiation Protocol (SIP). Service discovery is essential to locate targets for session transfer Shacham, et al. Expires May 21, 2008 [Page 1] Internet-D...
متن کاملProposal for a Tutorial Session at CDC-ECC’05
Hybrid systems have been an active area of research for a number of years. Recently a consensus is beginning to emerge among researchers about theoretical and applied problems related to control of hybrid systems that are both important and tractable. In this overview paper we survey recent research advances and highlight some of the open problems.

The hemisynthesis of the title compound, C22H32O2, was carried out through direct acetyl-ation reaction of the naturally occurring diterpene totarol [systematic name: (4bS,8aS)-4b,8,8-trimethyl-1-propan-2-yl-5,6,7,8a,9,10-hexa-hydro-phen-an-thren-2-ol]. The mol-ecule is built up from three fused six membered rings, one saturated and two unsaturated. The central unsaturated ring has a half-chair...

The title compound, C27H34O2, was hemisynthesized through direct benzoyl-ation of the naturally occurring meroterpene totarol. The central fused six-membered ring has a half-chair conformation, whereas the terminal six-membered ring displays a chair conformation. The dihedral angle between the fused benzene ring and the benzoyl benzene ring is 73.05 (14)°. The S,S chirality of the mol-ecule is ...
