1. NUMERICAL AND COMPUTATIONAL ASPECTS OF COSMO-BASED ACTIVITY COEFFICIENT MODELS
ABSTRACT In the present work, some numerical and computational aspects of COSMO-based activity coefficient models were explored. The residual contribution in such models rely on the so called self-consistency equation. This equation does not have a closed-form solution and is usually solved by the successive substitution method. The performance of a classica

2. Análise dinâmica, termodinâmica e microfísica de uma linha de instabilidade com o radar meteorológico móvel MXPOL / Microphysical, dynamic and thermodynamic analysis of a squall line using the mobile meteorological radar MXPOL
A prefrontal squal line (LI) that reached tne metropolitan area of São Paulo on April 26 2007 was monitored and analyzed by means of of surface and upper air measurements, weather radar and satellite data. Analyses indicate a favorable synoptic environment to form and sustain the LI. In its genesis region there was relatively warm and moiture air near the s

3. Metodologia computacional para o projeto de dispositivos semicondutores nanoestruturados / Computational methodology for the design of nanostructured semiconductor devices
Nanoestruturas semicondutoras como poços, fios e pontos quânticos possuem inúmeras aplicações de interesse tecnológico. Como exemplo pode-se citar sua utilização em lasers, detectores de infravermelho, transistores, spintrônica, na medicina e, prevê-se que, futuramente, sejam essenciais na computação quântica. O domínio dessa tecnologia é visa

5. Perfil longitudinal de CAE s : flutuações, simulação híbrida e a dependência de modelos de interações hadrônicas
The goal of this thesis is present a fast one dimensional hybrid method by Monte Carlo scheme to efficiently simulate the longitudinal development of extensive air showers up to the highest observed energies (>10 18eV). Based on precalculated pion showers and a bootstrap technique, the method predicts the average shower profile, the number of muons at detect

6. Um modelo de auto-consistência no método K.K.R. / A model of self-consistency in the method K.K.R.
Usamos o método KKR para a obtenção dos níveis de energia e densidades de carga do ferro FCC (fase paramagnética). Observamos que gerando o potencial cristalino a partir de diferentes configurações atômicas, a carga dentro da esfera é a mesma e os níveis de energia também o são a menos de uma constante aditiva. Verificamos também que a carga den

7. Normalization and analysis of DNA microarray data by self-consistency and local regression
A robust semi-parametric normalization technique has been developed, based on the assumption that the large majority of genes will not have their relative expression levels changed from one treatment group to the next, and on the assumption that departures of the response from linearity are small and slowly varying. The method was tested using data simulated

8. Use of muscle contraction formalism for kinesin in fast axonal transport.
The general procedure is discussed for calculating the velocity of a vesicle along a microtubule. The formalism used previously for isotonic contraction in muscle (with multiple actin sites for a given cross-bridge) can be employed. However, some modifications must be made: (i) the kinetic diagram must include a state in which kinesin is absent from a vesicl

9. Chaos in learning a simple two-person game
We investigate the problem of learning to play the game of rock–paper–scissors. Each player attempts to improve her/his average score by adjusting the frequency of the three possible responses, using reinforcement learning. For the zero sum game the learning process displays Hamiltonian chaos. Thus, the learning trajectory can be simple or complex, depen

10. Hypothesis testing and earthquake prediction.
Requirements for testing include advance specification of the conditional rate density (probability per unit time, area, and magnitude) or, alternatively, probabilities for specified intervals of time, space, and magnitude. Here I consider testing fully specified hypotheses, with no parameter adjustments or arbitrary decisions allowed during the test period.

11. Low atmospheric CO2 levels during the Permo- Carboniferous glaciation inferred from fossil lycopsids
Earth history was punctuated during the Permo-Carboniferous [300–250 million years (Myr) ago] by the longest and most severe glaciation of the entire Phanerozoic Eon. But significant uncertainty surrounds the concentration of CO2 in the atmosphere through this time interval and therefore its role in the evolution of this major prePleistocene glaciation. He

12. Self-consistent determination of the transition state for protein folding: Application to a fibronectin type III domain
We present a general approach in which theory and experiments are combined in an iterative manner to provide a detailed description of the transition state ensemble (TSE) for folding. The method is illustrated by applying it to TNfn3, a fibronectin type III domain protein. In the first iteration, a coarse-grained determination of the TSE is carried out by us
