Mapping the Global Offshoring Network Through the Panama Papers

Proceedings of the International Conference on Information Technology & Systems (ICITS 2018). Libertad City, EcuadorThis works maps the offshoring network between regions and countries worldwide through the Panama Papers. The Panama Papers 2016 divulgence is the largest leak of offshoring and tax avoidance documentation. The leaked documents contain 2.6 TB of information involving more than two hundred thousand of enterprises in more than two hundreds countries. Using the Offshore leaks database we related entities around the world through different types of relationships. These relationships were used in order to build an offshoring network at countries and geographical regions scales. The network is characterized and described using chord diagrams to map the intra and inter relation between the countries and regions, discovering which of them are the more prominent in the worldwide offshoring scenario.This work was funded by UAM-Santander CEAL-AL/2017-08, and UDLA-SIS.MG.17.02

Analysis of electricity markets with constraints

Constraint satisfaction techniques are mechanisms that can be used to ensure that all transactions in a electricity market can be completed without violating any operating limits. This is an important issue in an electricity market, because an improper handling of the constraints can divide the system and have a significant impact on the ability of the individual players to exercise market power. The main purpose of this paper is to present a methodology to guarantee a safe unit commitment in normal operation and after contingencies, using re-dispatch techniques after a topological analysis

O ENSINO APRENDIZAGEM DE ADOLESCENTES EM REGIME DE SEMILIBERDADE: ELEMENTO INDISSOCIÁVEL AO PROCESSO DE RESSOCIALIZAÇÃO E REINTEGRAÇÃO SOCIAL

O Estatuto da Criança e do Adolescente (ECA) no bojo de seu texto legal e na garantia da proteção integral da criança e do adolescente reafirma o direito a escolarização a adolescentes que estejam em cumprimento de medida socioeducativa em regime de semiliberdade. Assim, objetivou-se com esta pesquisa analisar os desafios e as possibilidades do ensino aprendizagem de adolescentes em conflito com a Lei em regime de semiliberdade para a garantia da ressocialização e reintegração social. Para tanto, utilizou-se estudo do tipo descritivo com enfoque qualitativo de investigação. A pesquisa ocorreu na Cidade de Belém do Pará tendo como Lócus de investigação o Centro de Adolescentes em semiliberdade (CAS) e a Escola Liceu das Artes e Ofícios Mestre Raimundo Cardoso, onde foi realizada entrevista semiestruturada para 12 (doze) adolescentes em regime de semiliberdade do CAS, a equipe multidisciplinar do CAS composta por psicólogo, pedagogo, assistente social, coordenação técnica e coordenação de monitoria, 03 (três) professores e um coordenador pedagógico da Escola Liceu das Artes e Ofícios Mestre Raimundo Cardoso, bem como a análise documental dos prontuários dos adolescentes em conflito com a lei do CAS e o projeto político pedagógico da escola lócus de pesquisa a análise de dados consistiu em uma análise descritiva e explicativa. Concluiu-se que os desafios são maiores que as possibilidades de que o adolescente em conflito com a lei possa a partir da escolarização alcançar sua reintegração e ressocialização para o exercício da cidadania.

Efficient excitation of waveguides in Crank-Nicolson FDTD

In this paper, we present a procedure to calculate the discrete modes propagated with Crank-Nicolson FDTD in metallic waveguides. This procedure enables the correct excitation of this kind of waveguides at any resolution. The problem is reduced to solving an eigenvalue equation, which is performed, both in a closed form, for the usual rectangular waveguide, and numerically in the most general case, validated here with a ridged rectangular waveguide.The work described in this paper and the research leading to these results has received funding from the European Community's Seventh Framework Programme FP7/2007-2013, under grant agreement no 205294 (HIRF SE project), and from the Spanish National Projects TEC2010-20841-C04-04, TEC2007-66698-C04-02, CSD2008- 00068, DEX-530000-2008-105, and the Junta de Andalucia Projects TIC1541 and P09-TIC-5327

Síntesis óptima de un mecanismo para la marcha bípeda utilizando evolución diferencial

ResumenEl diseño de la extremidad de un robot bípedo es un punto clave para mejorar la locomoción y el desempeño de robots bípedos. El empleo de mecanismos que reproduzcan la marcha no es una tarea sencilla ya que se requiere generar un movimiento en el espacio Cartesiano con más grados de libertad que los considerados en un mecanismo. En este trabajo se propone un mecanismo planar de ocho eslabones con un grado de libertad como extremidad bípeda y se analiza su comportamiento en el seguimiento de una trayectoria similar a la marcha. Para el diseño del mecanismo propuesto se establece formalmente la síntesis dimensional como un problema de optimización numérica. Con el propósito de obtener diseños viables dentro del espacio de las soluciones reales en el problema de optimización, se incorpora un mecanismo de manejo de restricciones en el algoritmo de evolución diferencial (ED) y se analiza el comportamiento del algoritmo bajo diferentes parámetros de cruza. Resultados experimentales comprueban el enfoque de diseño en un prototipo de laboratorio.AbstractThe limb design for a biped robot is a key issue to improve the locomotion and the performance of biped robots. The use of mechanism for tracking the gait is not an easy task because the degree of freedom (d.g.f) of the Cartesian space movement does not correspond to the d.g.f of the mechanism. Hence in this paper, an eight-bar planar mechanism with a one d.o.f is proposed as biped limb and the biped gait tracking behavior in the mechanism is analyzed. A numeric optimization problem is formally stated to design the proposed mechanism based on dimensional synthesis. A constraint handling mechanism is included into the differential evolution algorithm (DE) algorithm in order to obtain mechanism design with real solutions in the optimization problem and the behavior of the algorithm with different crossover parameters is analyzed. Experimental results verify the design approach in a laboratory prototype

Association between Food-Specific Immunoglobulin G4 Antibodies in Adults with Self-Reported Signs and Symptoms Attributed to Adverse Reactions to Foodstuffs

Signs and symptoms attributed to adverse reactions to foodstuffs (ARFS) need tools for research and evaluation in clinical practice. The objectives of this study were (a) to evaluate the most frequent self-reported signs and symptoms attributed to ARFS in Spanish adults, (b) to determine the prevalence of food-specific IgG4 antibody reactions (AbRs), and (c) to investigate the association between self-reported ARFS symptomatology and food-specific IgG4 AbRs. Food-specific IgG4 AbRs against 57 common food and beverages (AESKUCARE-T2FA® in vitro point-of-care test kit, Aesku.Diagnostics GmbH, Germany) were determined in capillary blood samples of 205 volunteers living in the Region of Madrid (Spain). The most frequent self-reported signs and symptoms were related to skin (43%), digestive (41%), and nervous system (NS, 33%) problems. The prevalence of food-specific IgG4 AbRs was cow’s milk (73%), sheep’s milk (70%), casein (66%), and goat’s milk (56.10%). Positive IgG4 AbRs against tomato had a profile consisting of 3/4 of skin problems, more than half of digestive, and 2/5 of NS self-reported signs and symptoms. In conclusion, at least 1/3 of the studied sample reported skin, digestive, and NS signs and symptoms. The most frequent food-specific IgG4 AbRs were related to dairy. Skin problems were more frequent in positive tomato IgG4 AbRs

Climatic Change in a Large Shallow Tropical Lake Chapala, Mexico

Measurements of temperature, currents and lake level taken in 2005–2014 are analyzed and discussed. We obtained a conceptually new data set on the formation of the thermocline in Lake Chapala. It is showed that the thermocline in the lake occurs only during the daytime, in the top 0.5–1.0-m layer of the water column, whereby the vertical temperature gradient reaches 2.5°C/m within that layer. At night, the top layer is cooled, which causes strong vertical mixing down to the bottom. Moored measurements of temperature and level from Lake Chapala reveal the presence of seiches oscillations with periods of 5.7 and 2.8 hours with amplitudes of 15.4 and 8.1 mm. Temperature measurements on sections across the lake showed that in the northern part of the lake, the water column is warmer that in southern 2–3°C in all seasons. The lake currents were simulated for wet and dry seasons. The model results are in good agreement with the acoustic Doppler current profiler (ADCP) data. The presence of an anticyclone gyre in the central part of the lake in both seasons is detected

The 2010 very high energy gamma-ray flare and 10 years of multi-wavelength observations of M 87

The giant radio galaxy M 87 with its proximity (16 Mpc), famous jet, and very massive black hole ((3-6) x 10(9) M-circle dot) provides a unique opportunity to investigate the origin of very high energy (VHE; E > 100 GeV) gamma-ray emission generated in relativistic outflows and the surroundings of supermassive black holes. M 87 has been established as a VHE gamma-ray emitter since 2006. The VHE gamma-ray emission displays strong variability on timescales as short as a day. In this paper, results from a joint VHE monitoring campaign on M 87 by the MAGIC and VERITAS instruments in 2010 are reported. During the campaign, a flare at VHE was detected triggering further observations at VHE (H.E.S.S.), X-rays (Chandra), and radio (43 GHz Very Long Baseline Array, VLBA). The excellent sampling of the VHE gamma-ray light curve enables one to derive a precise temporal characterization of the flare: the single, isolated flare is well described by a two-sided exponential function with significantly different flux rise and decay times of tau(rise)(d) = (1.69 +/- 0.30) days and tau(decay)(d) = (0.611 +/- 0.080) days, respectively. While the overall variability pattern of the 2010 flare appears somewhat different from that of previous VHE flares in 2005 and 2008, they share very similar timescales (similar to day), peak fluxes (Phi(>0.35 TeV) similar or equal to (1-3) x 10(-11) photons cm(-2) s(-1)), and VHE spectra. VLBA radio observations of 43 GHz of the inner jet regions indicate no enhanced flux in 2010 in contrast to observations in 2008, where an increase of the radio flux of the innermost core regions coincided with a VHE flare. On the other hand, Chandra X-ray observations taken similar to 3 days after the peak of the VHE gamma-ray emission reveal an enhanced flux from the core (flux increased by factor similar to 2; variability timescale <2 days). The long-term (2001-2010) multi-wavelength (MWL) light curve of M 87, spanning from radio to VHE and including data from Hubble Space Telescope, Liverpool Telescope, Very Large Array, and European VLBI Network, is used to further investigate the origin of the VHE gamma-ray emission. No unique, common MWL signature of the three VHE flares has been identified. In the outer kiloparsec jet region, in particular in HST-1, no enhanced MWL activity was detected in 2008 and 2010, disfavoring it as the origin of the VHE flares during these years. Shortly after two of the three flares (2008 and 2010), the X-ray core was observed to be at a higher flux level than its characteristic range (determined from more than 60 monitoring observations: 2002-2009). In 2005, the strong flux dominance of HST-1 could have suppressed the detection of such a feature. Published models for VHE gamma-ray emission from M 87 are reviewed in the light of the new data

Use of PDLC Film for Improving Visualization of Contents in Holographic Display Under Different Illumination Scenarios

AbstractPepper's ghost effect has been used since its beginnings at the second half of XIX century to generate 3D projections of virtual people in real environments. Nowadays this effect is used by ‘holographic’ displays for the projection not only of virtual people but also of objects and even animations that can interact with real objects. Marketing and product presentations are some of the most used applications for these displays. Nevertheless, another interesting application is been explored recently: knowledge transfer for both industrial and educational purposes. Regardless the application there is a little problem with these displays: when they are used in a high-illuminated place the contents projected are lost. That is the motivation for this project, which seeks to evaluate the use of a PDLC film (that allows to control its transmittance) to minimize these problem. Action research methodology is being used as a guideline for planning and executing the actions required in the project. The results were satisfactory; achieving an improvement in the visualizations of the contents displayed using the PDLC film
