This paper will describe the SMOS concept in terms of instrument (characteristics) investigates the main aspects of the retrieval capabilities of the 2-D microwave interferometer for monitoring soil moisture, vegetation biomass and surface temperature. The analysis is based on model inversion taking into account the instrument characteristics. The standard error of estimate of the surface varia...

In this paper we identify the needs and critical issues of management and monitoring in IP Multimedia Subsystem (IMS). As an IMS provides a layered architecture converging heterogeneous networks; it requires network management as well as service management. We provide a framework for managing an IMS system by utilizing network management server, session management and service managed objects (S...

Chinese academy of sciences) SMOS is a satellite dedicated to measuring soil moisture(SM) and sea surface salinity (SSS) continuously at a resolution around 50km from space for the first time in the history. It is also the first spaceborne mission that carries a synthetic aperture radiometer at L band. CAL/VAL is a big challenge to this kind of mission considering its frequency, resolution scal...

1997 ii ABSTRACT In a complex real-time environment, there is often a large amount of temporal data that needs to be promptly collected and made available for processing. To support time constrained access to this data, real-time databases are needed in order to provide predictable transaction time. However, the time constraints can be very tight, requiring a very high database performance leve...

Using the proposed Soil Moisture and Ocean Salinity (SMOS) mission as a case study, this paper investigates how the presence and nature of vegetation influence the values of geophysical variables retrieved from multi-angle microwave radiometer observations. Synthetic microwave brightness temperatures were generated using a model for the coherent propagation of electromagnetic radiation through ...

The sociological literature on social movement organizations (SMOs) has come to recognize that under neoliberal globalization many SMOs have moved from an emphasis on the state as the locus of change toward a focus on corporations as targets. This shift has led some SMOs to turn to forms of market-based private regulatory action. The use of one such tactic—voluntary, third-party product certifi...
