1. Investigation of the effect of nozzle design on rheological bioprinting properties using computational fluid dynamics
ABSTRACT Bioprinting is the utilization of techniques derived from three-dimensional printing to generate complex biological structures which may replace natural tissues or organs. It employs high spatial resolution deposition of different cell types, growth factors and biomaterials. Those together form bioinks, which are the bioprinting inputs, analogously

2. Adaptation of the Lanczos Algorithm for the Solution of Buckling Eigenvalue Problems
Abstract An adaptation of the conventional Lanczos algorithm is proposed to solve the general symmetric eigenvalue problem Kϕ = λK Gϕ in the case when the geometric stiffness matrix KG is not necessarily positive-definite. The only requirement for the new algorithm to work is that matrix K must be positive-definite. Firstly, the algorithm is presented fo

3. Analyzing the Unscented Kalman Filter Robustness for Orbit Determination Through Global Positioning System Signals
ABSTRACT: The nonlinear unscented Kalman filter (UKF) is evaluated for the satellite orbit determination problem, using Global Positioning System (GPS) measurements. The assessment is based on the robustness of the filter. The main subjects for the evaluation are convergence speed and dynamical model complexity. Such assessment is based on comparing the UKF

4. Especialización tecnológica, captura y formación de competencias bajo integración de mercados: comparación entre Asia y América Latina
The aim of this paper is to observe the evolution of technological specialization, convergence and the process of building technological competences for two groups of countries - Asia and Latin America - between 1985-1995 and 1999-2008. Between these periods, most of the countries in these groups registered growing levels of global integration in terms of go

5. Competitividade e restrição externa na Zona do Euro
The recent debt crisis in Greece, Ireland and Portugal has exposed the fragility existing in the Eurozone for promoting development and economic convergence between the countries that have adopted the currency. Way beyond the fear of insolvency, what is observed is a growing disparity of the most-developed countries in comparison to the less-developed ones,

6. Estimação e previsão da estrutura a termo das taxas de juros usando técnicas de inteligência computacional / Term structure of interest rate modeling and forecasting using computational intelligence techniques
This work proposes the term structure of interest rates modeling and forecasting using computational intelligence techniques, based on data from the US and Brazilian fixed income markets. The yield curve modeling includes the use of some evolutionary computation methods like Genetic Algorithms, Differential Evolution and Evolution Strategies in comparison wi

7. Metas de inflação numa economia pós-keynesiana / Inflation targeting in a post-keynesian economics
This dissertation analyses the compatibility of the inflation target system with an economic structure characterized as a post Keynesian one. This structure presents three elements: an IS relation; a relation similar to the Phillips curve but with a post Keynesian content; and an adaptive process of the formation of expectations for the inflation rate. Monet

8. Growth, structural change and technological capabilities Latin America in a comparative perspective
Countries differ in terms of technological capabilities and complexity of production structures. According to that, countries may follow different development strategies: one based on extracting rents from abundant endowments, such as labor or natural resources, and the other focused on creating rents through intangibles, basically innovation and knowledge a

9. The rates in complete moment convergence for negatively associated sequences
Let X1, X2,... be a strictly stationary and negatively associated sequence of random variables with mean zero and positive, finite variance, set Sn = X1+ ... + Xn, Mn = max1 < k < n |Sk|. Under appropriate moment conditions, we obtain precise rates in law of the logarithm for the moment convergence of Sn and Mn.

10. Sistema de monção da América do Sul: início e fim da estação chuvosa e sua relação com a Zona de Convergência Intertropical do Atlântico / The south american monsoon system: onset and demise of the rainy season and its relationship with the Atlantic Intertropical Convergence Zone
Physical, dynamic and thermodynamic aspects related to the South American Monsoon System (SAMS) are investigated for the 1979-2006 period. A new methodology to determine the onset and demise dates of the rainy season (ONR and DER, respectively) related to the SAMS is developed using the field of antisymmetric outgoing longwave radiation in relation to the eq

11. Características da precipitação pluviométrica do nordeste brasileiro e seus padrões de acoplamento com as TSM do Pacífico Equatorial e Atlântico Sul. / Rainfall characteristics in northeastern brazil and their patterns coupling with sst equatorial Pacific and South Atlantic.
The eastern coast of the Northeast Brazil (NEB) is a region where transient weather systems interact with local systems, modulating their frequency and intensity. Understanding the mechanisms of such interactions may be instrumental in explaining the observed precipitation patterns in this region. The objective of this work is quite within this scope and tak

12. Convergência da renda agropecuária em Minas Gerais, 1996-2006 / Agricultural income convergence in Minas Gerais, 1996-2006
In the last few years, Minas Gerais gradually increased its participation in national agricultural GDP. Currently, Minas Gerais is the main producer of coffee beans, milk, potatoes and garlic, also having the largest horses herd and the second largest cattle herd in the country. However, due to regional differences, the process of agricultural development ha
