Clickable Bambusurils to Access Multivalent Architectures

Organic Letters, 2020
Propargylated bambus[4,6]urils were prepared by an efficient one-step condensation of dipropargylglycoluril with formaldehyde under microwave irradiation. Their functionalization by click chemistry (CuAAC) afforded new multivalent architectures decorated with 8 or 12 ligands.

Access network target architecture

Proceedings of IEEE International Conference on Multimedia Computing and Systems, 2002
Access networks have always been a very significant part of public network operator investments and operating costs. They have, however, not been a very dynamic part of telecom networks, planned, as they were, for the long-term and usually with limited technological innovation.

ATM access network architecture

ICC 91 International Conference on Communications Conference Record, 2002
The requirements of the ATM (asynchronous transfer mode) access network architecture, its physical and logical network configurations and its OAM (operation and maintenance) architecture are described. A topology that layers ring/star networks and star networks is proposed for the physical network configuration to allow access network evolution ...

Photonic access network architecture

IEEE Global Telecommunications Conference GLOBECOM '91: Countdown to the New Millennium. Conference Record, 2002
A photonic access network architecture is proposed that can create the large capacity and extremely flexible network needed to offer B-ISDN (broadband integrated services digital network) services economically. The networks are characterized by increased management flexibility and line capacity.

An Access Control Architecture for Context-Risk-Aware Access Control: Architectural Design and Performance Evaluation

2010 Fourth International Conference on Emerging Security Information, Systems and Technologies, 2010
Risk assessment plays a significant role in Decision Support Systems (DSS). Recently, there have been efforts to exploit the potential of linking risk assessment to security provisioning to provide risk-aware security services. One of these efforts is the Context-Risk-Aware Access Control (CRAAC) model that links requesters' access privileges to the ...
