A Novel Formulation of Economic Model Predictive Control for Periodic Operations

This paper proposes a novel formulation of economic model predictive control (MPC) for linear systems with periodic operations. In this economic MPC design, the optimal periodic trajectory from an economic point of view is unknown, hence it is not possible to follow a standard control strategy in which the MPC uses this trajectory to define a terminal constraint to guarantee closed-loop convergence. The economic cost function is optimized with a periodicity constraint at each time step considering all periodic trajectories in a period including the current state. The recursive feasibility and closed-loop convergence to the optimal periodic trajectory are analyzed using the Karush-Kuhn-Tucker conditions. Finally, two simulations are provided to demonstrate the main results.Agencia Estatal de Investigación DPI2013-48243-C2Agencia Estatal de Investigación DPI2016-76493- C3Ministerio de Ciencia, Innovación y Universidades MDM-2016-065

Caracterização morfobiológica, morfométrica e ultraestrutural de isolados silvestres de Trypanosoma cruzi do estado do Rio de Janeiro, Brasil

Triatoma vitticeps is a triatomine with geographic distribution restrict to Brazil, which exhibits high prevalence of Trypanosoma cruzi natural infection. Of special epidemiologic concern, this species often invades households in the states of Rio de Janeiro, Minas Gerais and Espirito Santo. The objective of this study was to evaluate morphological and ultrastructural parameters on three T. cruzi isolates obtained from wild T. vitticeps specimens. The growth and cell differentiation of the parasite was evaluated through epimastigote and trypomastigote forms obtained in the growth curves for three distinct isolates. The maximum growth showed differences at the 20th day of the curve. Our in vitro results show a heterogeneity, regarding these features for samples cultivated under the same conditions. Morphometric analyzes based on the shape of epimastigotes and trypomastigotes corroborated such differentiation. These results highlight the need of better understanding the meaning of this diversity under an eco-epidemiological perspective792294303COORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPESFUNDAÇÃO CARLOS CHAGAS FILHO DE AMPARO À PESQUISA DO ESTADO DO RIO DE JANEIRO - FAPERJTriatoma vitticeps é um triatomíneo com distribuição geográfica restrita ao território brasileiro, apresentando alta prevalência de infecção natural pelo Trypanosoma cruzi.

Arrival Cities

The impact of migrating artists on modern art Exile and migration played a critical role in the diffusion and development of modernism around the globe, yet have remained largely understudied phenomena within art historiography. Focusing on the intersections of exile, artistic practice, and urban space, this volume brings together contributions by international researchers committed to revising the historiography of modern art. It pays particular attention to metropolitan areas that were settled by migrant artists in the first half of the 20th century. These arrival cities became hubs of artistic activities and transcultural contact zones where ideas circulated, collaborations emerged, and concepts developed. Taking six major cities as a starting point — Bombay (now Mumbai), Buenos Aires, Istanbul, London, New York, and Shanghai — the authors explore how urban topographies and landscapes were modified by exiled artists re-establishing their practices in these and other metropolises across the world. Questioning the established canon of Western modernism, Arrival Cities investigates how the migration of artists to different urban spaces impacted their work and the historiography of art. In doing so, it aims to encourage the discussion between scholars from different research fields, such as exile studies, art history, architectural history, design history, urban studies, and history.

Specification Cases: a lightweight approach based on Natural Language

Use Cases are one of the most used artifacts in software requirements specifications. Although there are a lot of templates that suggests how to describe Use Cases, as well as many quality inspection techniques, there are no many techniques to deal with the complexity and the effort to produce good quality Use Cases. On top of that, Use Cases are biased towards user interaction, leaving out important domain information. Thus, it is necessary to provide techniques to incrementally describe specifications that goes beyond user interaction but which can be derived from simpler artifacts in order to make the process organized and effective. This paper proposes an approach to begin with very simple sentences (kernel sentences), following with the LEL glossary and Scenarios, in order to describe Specification Cases. The approach relies on already defined kernel sentences and suggests three procedures to reorganize the knowledge captured in kernel sentences to describe the LEL, then Scenarios and finally Use Cases. This paper also reports a preliminary evaluation that supports the applicability and usability of the approach

Artificial Pancreas: First Clinical Trials in Argentina

The first clinical trials using an Artificial Pancreas (AP) in Latin America have been defined in 2 stages. The first stage was carried out in November 2016 with the UVA controller (developed by the Center for Diabetes Technology and already clinically tested), and the second will be performed during the first semester of 2017 with the ARG (Automatic Regulation of Glucose) algorithm (developed by ITBA, UNQ, and UNLP in Argentina). Both tests are based on the DiAs (Diabetes Assistant) from the UVA, and are performed in the HIBA on 5 patients with Type 1 Diabetes Mellitus (T1DM), for 36 hours. For the first stage, Open-Loop (OL) insulin boluses were applied before meals and patient’s physical activity was included. On the other hand, for the second stage, patients will not be involved in physical activity, but no OL insulin boluses will be injected before meals. In this work, experimental results from the first stage with the UVA controller, and preliminary results with the ARG control algorithm tested on the UVA/Padova simulator are presented. Due to the final paper deadline, the experimental results from the second stage are not included here, but will be presented at the IFAC World Congress.Facultad de IngenieríaInstituto de Investigaciones en Electrónica, Control y Procesamiento de Señale

Re-thinking feminism and democratic politics: the potential of online networks for social change and gender equality in Brazil

The relationship between women and new technologies has been an important area of research for feminist sociologists and others working with gender and cultural studies (i.e. Gill, 2012; Sassen, 2002), as well as for scholars within the GAD (Gender and Development) empowerment framework (Gajjala, 2003). A significant body of international scholarship on gender and the Internet has also developed in the last decades throughout the world (i.e. Haraway, 1991, 2000; Plant, 1995; Harcourt, 2000; Sandoval, 2000; Sutton and Pollock, 2000), including emerging research in Brazil (i.e. Ferreira, 2015; Natansohn, 2013; Matos, 2017). Many Brazilian women, who do not feel represented in the mainstream media and who struggle to have a voice, have increasingly made use of new technologies for self-expression, civic engagement and political mobilization. This article provides a critical summary of feminist theoretical perspectives on the potential of online communications for women's rights, further sketching a brief case study of contemporary Brazilian feminism and the mobilization around women's rights, particularly in the year 2015. This is done through a discussion of the discursive online practices of websites like Blogueiras Feministas and the NGO Think Olga, part of a wider project (Matos, 2017). Questions asked include how the media can better contribute to assist in gender development, and how online platforms can make a difference. I argue that despite constraints and setbacks, the seeds of a wider transformative influence in the offline world are slowly being planted in a highly fragmented, heterogenous and erratic blogosphere
