In recent years, there has been strong interest in neuroscience studies to investigate brain organization through networks of brain regions that demonstrate strong functional connectivity (FC). Several well-known functional networks have been consistently identified in both taskrelated and resting-state fMRI across different study populations. These networks are extracted from observed fMRI usi...

Monitoring river water quality with satellite data has been limited by the lack of sensors offering high revisit frequency and suitable spatial and radiometric resolutions. In this communcation, it is shown that the last generation of moderate resolution sensors makes possible to monitor efficiently large tropical basins characterized by reduced field monitoring and strong cloud coverage. Empha...

In this paper, we consider the limited feedback Transmitting Beamforming for (multiple in single out) MISO systems. In conventional techniques, all vectors of a large codebook (CB), used for the feedback of the quantized channel state information (CSI), are broadcasted to all users, in a guard period which is followed by data burst periods. Instead of transmitting a large number of codevectors,...

This study developed a methodology to temporally classify large scale, upper level atmospheric conditions over North America, utilizing a newly-developed upper level synoptic classification (ULSC). Four meteorological variables: geopotential height, specific humidity, and u- and v-wind components, at the 500 hPa level over North America were obtained from the NCEP/NCAR Reanalysis Project datase...

Water-quality managers desire information on the temporal and spatial variability of contaminant concentrations and the magnitudes of watershed and bed-sediment loads in San Francisco Bay. To help provide this information, the Regional Monitoring Program for Trace Substances in the San Francisco Estuary (RMP) takes advantage of the association of many contaminants with sediment particles by con...

environmental management and planning and benefiting from climatic capacities of every geographical place are related to homogenous climatic regions and the most influential climatic elements in spatial separation of the climatic regions. accordingly, the aim of the present study includes determining the most influential climatic elements affecting on the climate of esfahan province, and the sp...

Uncertainty exists concerning the links between synoptic-scale processes and tornado outbreaks. With continuously improving computer technology, a large number of high-resolution model simulations can be conducted to study these outbreaks to the storm scale, to determine the degree to which synoptic-scale processes appear to influence the occurrence of tornado outbreaks, and to determine how fa...

due to deep, complex and everlasting interaction between precipitation and climatic elements-factors, there are changes and varieties in both time and space dimensions. so that climate experts and related scientists take their attentions to this phenomenon. an approach to do this kind of investigations is to describe spatial variations based on spatial statistics. in this paper the main object ...

5 Multiscale analysis is used to derive two sets of coupled models, each based on the same distinguished limit, to represent the interaction of the midlatitude oceanic synoptic scale — where coherent features such as jets and rings form — and the mesoscale, defined by the internal deformation scale. The synoptic scale and mesoscale overlap at low and mid latitudes, and are hence synonymous in m...
