13. Processamento adaptativo para cancelamento da interferencia de polarização cruzada em sistemas radio digitais
A interesting approach to improve the spectral efficiency of a digital radio system is the utilization the frequency reuse technique. However due to of the propagation impairments, there exist mutual interference between these two orthogonal channels, known as cross polarization interference. This work studies the interference cancellation by means of adapti

14. Synthetic neural modeling applied to a real-world artifact.
We describe the general design, operating principles, and performance of a neurally organized, multiply adaptive device (NOMAD) under control of a nervous system simulated in a computer. The complete system, Darwin IV, is the latest in a series of models based on the theory of neuronal group selection, which postulates that adaptive behavior is the result of

15. Measurement of marine picoplankton cell size by using a cooled, charge-coupled device camera with image-analyzed fluorescence microscopy.
Accurate measurement of the biomass and size distribution of picoplankton cells (0.2 to 2.0 microns) is paramount in characterizing their contribution to the oceanic food web and global biogeochemical cycling. Image-analyzed fluorescence microscopy, usually based on video camera technology, allows detailed measurements of individual cells to be taken. The ap

16. Monte Carlo-based adaptive EPID dose kernel accounting for different field size responses of imagers
The aim of this study is to present an efficient method to generate imager-specific Monte Carlo (MC)-based dose kernels for amorphous silicon-based electronic portal image device dose prediction and determine the effective backscattering thicknesses for such imagers. EPID field size-dependent responses were measured for five matched Varian accelerators from
