title: Relative Motion Guidance, Navigation and Control for Autonomous Orbital Rendezvous

description: ABSTRACT: In this paper, the dynamics of the relative motion problem in a perturbed orbital environment are exploited based on Gauss' variational equations. The relative coordinate frame (Hill frame) is studied to describe the relative motion. A linear high fidelity model is developed to describe the relative motion. This model takes into account primary gravitational and atmospheric drag perturbations. In addition, this model is used in the design of a control, guidance, and navigation system of a chaser vehicle to approach towards and to depart from a target vehicle in proximity operations. Relative navigation uses an extended Kalman filter based on this relative model to estimate the relative position and velocity of the chaser vehicle with respect to the target vehicle and the chaser attitude and gyros biases. This filter uses the range and angle measurements of the target relative to the chaser from a simulated Light Detection and Ranging (LIDAR) system, along with the star tracker and gyro measurements of the chaser. The corresponding measurement models, process noise matrix and other filter parameters are provided. Numerical simulations are performed to assess the precision of this model with respect to the full nonlinear model.The analyses include the navigations errors, trajectory dispersions, and attitude dispersions.

title: Comparison between traditional project appraisal methods and uncertainty analysis applied to mining planning

description: Abstract Long-term mining planning is a complex process which involves a large number of variables and uncertainties. Traditional discount cash flow (DCF) is usually used in the evaluation of mining projects. DCF includes net present value (NPV), internal rate of return (IRR), and profitability index (PI). A sensitivity analysis is usually carried out to evaluate the impact of the main variables on the project. Another way to measure uncertainties is through the Monte Carlo simulation (MCS). The objective of this study is to evaluate and compare the DCF methods and measure uncertainties through sensitivity analysis and MCS in the evaluation of mine sequencing. A case study of a phosphate mine project was used to chart the comparative study. In the results, NPV and uncertainty analysis through MCS were more consistent.

title: Cartography of internal migration in Mozambique between 1997 and 2007

description: Abstract The paper “Cartography of internal migration in Mozambique between 1997and 2007” results from an exploratory analysis of information pertaining to internal migration based on demographic census data between 1997 and 2007 respectively; the second and third censuses of Mozambique following national independence in 1975. The analysis is made according to the lifelong or accumulated migration observed among Mozambique’s eleven provinces in the censuses of 1997 and 2007. Also registered is migration in the five-year period before the demographic census of 2007 (that is, the period between 2002 and 2007). As a result of this analysis, the paper presents migration flows among provinces and also the volume of accumulated migration by sex and province, in 1997 and 2007. These data are presented as the volumes of inter-provincial migration of five-year 2002-2007. Furthermore, the analysis permits the grouping of the provinces in three categories according migratory trends: the first is composed of immigration provinces (Niassa, Manica and Maputo); the second of emigration provinces (Zambezia, Tete, Inhambane and Gaza); and the third, of provinces which from one period to another, changed the migration trend (Sofala, Cabo Delgado, Nampula and the City of Maputo). Lastly, the results indicate that in southern provinces of Mozambique, the proportion of women in total volume of migrants surpasses the proportion of men.

title: Entropy in peri-urbanization: inequality in access to transport infrastructures in Tonalá, Mexico

description: Abstract Mobility in the peri-urban strips has been experiencing multifaceted allometric growth, manifested in infrastructures for primarily motorized transport systems, which are characterized by obvious transformations and morphological configurations that converge with the entropy in the city system. Although this is not exclusive of peripheries, this is where deficiencies and inadequacies for some are intensified and recalcitrant improvements for others. This paper reviews the physical conditions and access to mobility infrastructures in the southeast of the municipality of Tonalá, Jalisco-México. From a system approach, we performed a quasi-ethnographic exercise aided by photographic records and satellite images. The results suggest that the urban-territorial planning process is inequitable and does not represent the negentropic force necessary to regulate the thermodynamics related to the exercise of living the city. In other words, there has been a lack of systemic conception in the planning process, originating excessive costs and time in the peri-urban mobility.

title: Economical availability of cará flour in diets for commercial laying hens

description: SUMMARY The objective of this study was to analyze the economical availability of cará flour in diets for laying hens. The experiment lasted 84 days in four periods of 21 days. 144 Hissex White hens with 39 weeks of age were used. Cará flour was used as diets energy source. The experimental design was completely randomized with six treatments of cará flour levels (0, 5, 10, 15, 20 and 25%) with four replicates of six birds each. The data were analyzed for polynomial regression at 5% of significance. Significant differences were observed (P&gt;0.05) in the economic analysis of food costs in egg production, revenue analysis and profitability of laying hens, with better results at 5% of cará flour inclusion. Observed too a decrease in profitability from these inclusion levels. From these results, it was concluded that the cará flour can be used as an energy alternative food in diets for commercial laying hens, with the inclusion level of 5% shown better results of economic performance. From 15% of inclusion, observed significant economic losses.

title: DRY FOREST DEFORESTATION DYNAMICS IN BRAZIL’S PONTAL BASIN

description: ABSTRACT Reliable information on vegetation cover and its dynamics over time is essential for managing life, resources, and supporting policies. Although many related initiatives have been undertaken in Brazil since the 1980s, knowledge about its dry forests is still limited. In this study, we address the drivers of deforestation and their threat to the Brazilian dry forest called Caatinga. We evaluated the land cover dynamics and landscape metrics in the watershed of the Pontal River, as it has become one of the most socially and environmentally important areas in Brazil. The overall process consists of a systematic sampling grid of hydrological samples, where Landsat images (1975 to 2013) combined with the FRAGSTATS package were used to evaluate landscape metrics indices for the Caatinga. Data showed that the relative area (RA) decreased from 90.25% to 60.98% over the 38-year period, while fragmentation (PD) presented an increasing bias. In addition, the spatial distribution of both indices became more heterogeneous and clustered in the north. We suggest that appropriateness of land for farming was the leading cause of deforestation; rainfall is 112% more intense in the north of the watershed than in the south. Therefore, the northern fauna and flora have been significantly altered and reduced. The relationship between deforestation and time shows an increasing threat. Further studies evaluating these causes are needed to improve our understanding of the vegetation dynamics in this region.

title: A rare case of giant verruciform xanthoma in the palate

description: Verruciform xanthoma represents a rare disease of unknown etiology that typically affects the oral mucosa. In most cases, it is asymptomatic and characterized by a well demarcated elevation with irregular or papillary surface. The gums are the most affected oral site, and the lesion is usually less than 2 cm in diameter. The aim of this study is to report a rare case of an extensive verruciform xanthoma in the hard palate and gums of a 55-year-old male. Clinically, the well delimitated, reddish, elastic lesion measuring approximately 2.8 X 1.5 cm had a slightly granular surface. Histopathological analysis found proliferative epithelial activity with evident papillomatosis, parakeratosis, and large epithelial ridges. Xanthomatous cells with clear, vacuolated cytoplasm were detected in the lamina propria. The patient has been disease free for 18 months. According to an extensive research in the PubMed, MEDLINE, and Lilacs databases, this paper describes one of the most extensive cases of verruciform xanthoma reported in the literature.

title: What does Neuroscience have to tell us (or not yet) about metaphor processing?

description: Abstract: Neuroimaging research on the processing of metaphor presents different findings, which implies difficulties in formulating a theoretical paradigm of the metaphor in a neurological perspective. In this study, we argue that the lack of clarity of conceptual aspects about metaphor from a linguistic perspective implies diversities in the experiments design and incongruities in the findings. To support this argument, we present a qualitative meta-analysis of a corpus composed of 20 fMRI experiments on the processing of metaphor, under two aspects: the conceptual foundations of metaphor and the findings obtained in the experiments. As a result, we find that the absence of a dialogue between Neuroscience and Linguistics about the metaphor properties results in a problematic delimitation of a metaphor processing pattern under a neurological bias.

title: Variability of the Leaf Area Index in natural fields and transition forest in Southern Amazonas State, Brazil

description: The Leaf Area Index (LAI) has strong influence on ecosystems' energy and mass exchange and is fundamental to the understanding of regional climate changes and ecosystem dynamics. The main goal of this work was to establish, based on geostatistical analyses, the variability and spatial dependence of LAI in the natural fields and transitional forest in southern Amazonas State, in Brazil. The LAI was measured in a regular grid with 33 points at each studied area. Field measurements were done using the canopy analyser LAI-2000, which calculates the structure of the vegetation based on the radiation beneath the tree canopy. The average values of LAI varied according to the studied sites: the highest values were found in the transitional forest (4.42 m²m-2), followed by the high (2.03 m²m-2) and low (1.72 m²m-2) natural fields. All studied sites showed spatial dependence according to the kriging methods, but with different degrees of dependence: spatial dependence was moderate at the transition forest and weak at the natural fields. In the more arboreal open field, the maximum limit at which the points are correlated reached a distance of 35.3 m. The kriging maps proved to be very important tools for describing the spatial distribution of LAI in the Amazon.
