Iterative reconstruction techniques employ an initial estimate of voxel attenuation to predict projection data; estimates of voxel attenuation are iteratively adjusted to minimize the difference between the predicted projection data and the measured projection data.
We make the assumption that there are correlated groups of variables in the data, and restrict the projection matrix V x to a clustering-type of matrix, where each variable comes from exactly one factor.
A million fewer tourists came to New York City last year than were expected, new data show, and the projection for 2001 has been cut by nearly two million, as the cooling economy curtails the surge in visitors both from the United States and abroad.
Pressure data and the corresponding projection images were used to create composite images (Fig. 3).
The transfer function was been used here to estimate the past indoor humidity in the Cartoon Gallery from the Gatwick MIDAS data and the UKCP09 projections as shown in Figure 6a, which displays both the outdoor values (filled and open squares for MIDAS and UKCP09) and circles for the estimates of indoor conditions.
According to Eq. (46), the Gauss noise is added into the ideal projection data, and the low-dose noise projection data is simulated (g j = 200, κ = 4 × 104).
The buoyant mood reflects recent data and projections: –The three largest firms, Tata Consultancy Services (TCS), Infosys and Wipro, each outperformed the Bombay Sensitive Index during 2009.
To bypass these limitations, we investigate an alternative approach, which entails the derivation of the MAR model directly on MEG sensor data and its projection into the source space.
The meteorological data for the baseline and the projection periods were created similarly to the method used by Adam et al. (2009).
