Opis:
The core components of NATO's automated information systems (AIS) include directory services (DS), e-mail, web services, and military message handling systems (MMHS) to exchange information with similar capabilities in NATO's member nation systems or systems that are under control of multi-national coalitions. NATO has developed the concept of information exchange gateways (IEGs) to meet this requirement. This paper introduces the concept of combining symmetric co-operative zones (CZs) to form these information exchange gateways. A generic framework for the co-operative zone network and security architecture is introduced in support of co-operative zone development. It is shown how a co-operative zone network interface can be integrated with the NATO general-purpose segment communications system (NGCS). Development of the NATO co-operative zones is based on an evolutionary approach. A baseline co-operative zone configuration, supporting directory services, e-mail and web services, has been tested and validated on the allied systems interoperability testbed (ASIT). This paper reports the results of the test and validation program. The paper concludes with an overview of planned evolutionary steps for co-operative zone development. Subjects covered in this overview are extension of information services, enhancement of security architecture, and operational deployment (i.e., scalability and manageability).

Opis:
Measurements of 1/f noise in Si and Si0.64Ge0.36 PMOSFETs have been compared with theoretical models of carrier tunnelling into the oxide. Reduced noise is observed in the heterostructure device as compared to the Si control. We suggest that this is primarily associated with an energy dependent density of oxide trap states and a displacement of the Fermi level at the SiO2 interface in the heterostructure relative to Si. The present study also emphasizes the important role of transconductance enhancement in the dynamic threshold mode in lowering the input referred voltage noise.
