1. Spatial and temporal distribution of Gymnorhamphichthys rondoni (Gymnotiformes: Rhamphichthyidae) in a long-term study of an Amazonian terra firme stream, Leticia - Colombia
ABSTRACT Weakly electric fishes continually emit electric organ discharges (EOD) as a means of communication and localization of objects in their surroundings. Depending on water conductivity, the amplitude of the electric field generated is known to increase with decreases in electrical conductivity of the water. In Amazonian terra firme streams, water cond

2. ¿Puede el cine darnos qué pensar? Wong Kar-Wai y la poética del des-encuentro
Abstract: Is it possible for the cinema to philosophize? Can the moving image work as a means for philosophy to operate under a different expressive language? This article discusses the ability of certain cinemas (especially modern cinema) to do philosophy on the big screen. It describes the theoretical approaches that argue for a philosophical cinema capabl

3. NETWORK FLOW ORIENTED APPROACHES FOR VEHICLE SHARING RELOCATION PROBLEMS
ABSTRACT Managing a one-way vehicle sharing system means periodically moving free access vehicles from excess to deficit stations in order to avoid local shortages. We propose and study here several network flow oriented models and algorithms which deal with a static version of this problem while unifying preemption and non preemption as well as carrier ridi

4. A Software-in-the-Loop Simulation Scheme for Position Formation Flight of Multicopters
ABSTRACT The cooperative control of small unmanned aerial vehicles such as the multicopters has been extensively investigated worldwide for functionality augmentation and cost reduction with respect to a single larger vehicle. The present paper proposes a software-in-the-loop simulation scheme for performance evaluation and demonstration of formation flight

5. Numerical Study of Reduced Frequency Effect on Longitudinal Stability Derivatives of Airfoil under Pitching and Plunging Oscillations
ABSTRACT In this study, incompressible, unsteady and turbulent flow over an airfoil with pitching and plunging oscillations is numerically studied in order to investigate the effect of reduced frequency on stability derivatives of oscillating airfoil. Linear k – ε model called Launder-Sharma and Rhie and Chow model are used for turbulence modeling and ove

6. Existência e homogeneização para um problema elíptico com fronteira livre não estacionária / Existence and homogenization for an elliptic problem with nonstationary free boundary
In this dissertation we study an elliptic problem in a bounded Lipschitz domain. Part of the boundary is moving and oscillates rapidly in the variable representing the space. Thus, we have a multi-scale free boundary problem. This problem has applications, for instance, in the construction of semiconductor films taking into account that the surface of the fi

7. Aplicação do controle estatístico de processo (CEP) como ferramenta para a melhoria da qualidade do leite / Application of statistical process control (SPC) as a tool for improvement of milk quality
This study aimed to employ statistical process control (SPC) as a tool to improve milk quality. The first objective of the study was to evaluate SPC as tool to identify non-natural variation of milk quality that are possible to be manipulated. In this study, data on milk production, somatic cell count (SCC), and total bacterial count (TBC) of 384 farms were

8. Editorial
Usually one can find three subjects in the first year of the syllabus of any technical engineering career, namely, calculus, general physics and programming. Being physics a matter lying on the grounds of technical engineering it becomes naturally appropriate to introduce the use of calculus and programming as useful tools in the context of a physics problem

9. Solving the dual subproblem of the Method of Moving Asymptotes using a trust-region scheme
An alternative strategy to solve the subproblems of the Method of Moving Asymptotes (MMA) is presented, based on a trust-region scheme applied to the dual of the MMA subproblem. At each iteration, the objective function of the dual problem is approximated by a regularized spectral model. A globally convergent modification to the MMA is also suggested, in whi

10. Entre corpos, tempos e sujeitos : ciências, políticas e artes improvisando identidades / Between bodies, times and subjects : sciences, politics and arts improvising identities
This dissertation concerns the ways that science and art are responsible for the creation of politics that have an effect on bodies, times and subjects. Science is discussed in so much as it mobilizes and is mobilized in a politics of identity, taking as a point of departure the topic of race and racism in Brazil; and the strategies adopted by the forces of

11. Dynamic load-balancing : a new strategy for weather forecast models
Weather forecasting models are computationally intensive applications and traditionally they are executed in parallel machines. However, some issues prevent these models from fully exploiting the available computing power. One of such issues is load imbalance, i.e., the uneven distribution of load across the processors of the parallel machine. Since weather

12. Ética procedimental e racionalidade da ação: uma leitura crítica da teoria política de Jürgen Habermas / Proceduralist ethics and rationality of action: a critical reading of Jürgen Habermaspolitical theory
In this dissertation, I analyze political theory currents which claim that political and social individual actions rely on individuals rationality. From this perspective, I present the dispute between a proceduralist understanding of justice and a concept of proceduralist ethics which rests upon the existence of cultural community of values. Then, I discuss
