1. Link Optimization and Performance Analysis of a 40 Gbps DQPSK Modulated Ultra DWDM System with 32 Orthogonally Polarized channels
Abstract The demand for higher speed at a lesser transmission cost per bit resulted in growth of optical networks with improved spectral efficiency even at narrower channel spacing. Incorporation of multilevel modulation formats in DWDM system led to the exploration of the 25 GHz channel grid, popularly known as Ultra Dense Wavelength Division Multiplexed (U

2. A globalização e a regulação da complexidade social por meio de sistemas jurídicos e suas redes sancionatórias
A globalização, as grandes alterações sociais, científicas, tecnológicas fizeram com que a sociedade atual passasse, cada vez mais, a tornar-se um ambiente complexo. Tamanha complexidade gerou nos cidadãos uma sensação crescente de medo e insegurança. Como reflexo destes sentimentos, o Direito é chamado para regular as novas relações sociais. En

3. Experimental analysis of all-optical 4-ASK signal generation through parametric amplification
We present experimental results concerning a new alloptical technique that multiplexes two binary signals into a quaternary one (4-ASK). The technique is based on parametric amplification. Values of the quaternary levels obtained experimentally, as a function of the extinction ratios of the binary input signals, show a rather good agreement with the simulate

4. O problema de falÃncia: uma abordagem experimental acerca do comportamento dos agentes econÃmicos
The continuous necessity of improving the business environment has led the nations to reform their bankruptcy laws. Those reforms are many times inspired on foreign legislations aspects, with very distinct bias towards creditorsâ rights defense, and in Brazil it wasnât different. The old Brazilian bankruptcy system ages from 1945, and it was not compatible

5. Systemic analysis of noise penalties all-optical network / AnÃlise sistÃmica das penalidades de ruÃdo nas redes Ãpticas transparentes
In this thesis, the routing and wavelength assignment processes are addressed. Besides of considering the network layer resources (number of available wavelengths in a link), the impact of physical layer effects in the transmitted optical signals is analyzed for both processes. The optimization of the wavelength assignment process is obtained by minimizing t

6. Analysis of optical CDMA systems / Análise de sistemas CDMA ópticos
The evolution of optical networks verified in the last few years has been characterized by the search for better bandwidth utilization efficiency. The successful implementation of practical code division for multiple access techniques (CDMA) in mobile communications systems has stimulated new investigations on this topic, particularly in the optical domain (
