description: This contribution is oriented to ways of computer vision algorithms for mobile robot localization in internal and external agricultural environment. The main aim of this work was to design, create, verify and evaluate speed and functionality of computer vision localization algorithm. An input colour camera data and depth data were captured by MS® Kinect sensor that was mounted on 6-wheel-drive mobile robot chassis. The design of the localization algorithm was focused to the most significant blobs and points (landmarks) on the colour picture. Actual coordinates of autonomous mobile robot were calculated out from measured distances (depth sensor) and calculated angles (RGB camera) with respect to landmark points. Time measurement script was used to compare the speed of landmark finding algorithm for localization in case of one and more landmarks on picture. The main source code was written in MS Visual studio C# programming language with Microsoft.Kinect.1.7.dll on Windows based PC. Algorithms described in this article were created for a future development of an autonomous agronomical mobile robot localization and control.

description: We study the behaviour of spinning test particles in the Schwarzschild spacetime. Using Mathisson-Papapetrou equations of motion we confine our attention to spatially circular orbits and search for observable effects which could eventually discriminate among the standard supplementary conditions namely the Corinaldesi-Papapetrou, Pirani and Tulczyjew. We find that if the world line chosen for the multipole reduction and whose unit tangent we denote as $U$ is a circular orbit then also the generalized momentum $P$ of the spinning test particle is tangent to a circular orbit even though $P$ and $U$ are not parallel four-vectors. These orbits are shown to exist because the spin induced tidal forces provide the required acceleration no matter what supplementary condition we select. Of course, in the limit of a small spin the particle's orbit is close of being a circular geodesic and the (small) deviation of the angular velocities from the geodesic values can be of an arbitrary sign, corresponding to the possible spin-up and spin-down alignment to the z-axis. When two spinning particles orbit around a gravitating source in opposite directions, they make one loop with respect to a given static observer with different arrival times. This difference is termed clock effect. We find that a nonzero gravitomagnetic clock effect appears for oppositely orbiting both spin-up or spin-down particles even in the Schwarzschild spacetime. This allows us to establish a formal analogy with the case of (spin-less) geodesics on the equatorial plane of the Kerr spacetime. This result can be verified experimentally.

description: Agriculture as the primary sector has gained increased attention in terms of its environmental implications. Based on the reform of Common Agricultural Policy, there is a link of direct payments to requirements that farmers maintain land in good agricultural and environmental condition and obey the relevant environment legislation since 2003. The aim of our work is the evaluation of agri-environmental performance of 27 European Union member states (we do not consider Croatia as it is the newest member state and there are missing data). We employ data envelopment analysis to calculate environmental efficiency, and Malmquist index for quantification of productivity change with respect of environmental performance. The results show that in terms of agri-environmental efficiency scores Hungary, Malta, Luxembourg and Netherland are the only efficient countries over the whole observed period (2008-2012). The average output-oriented environmental efficiency is found to be 2.4 over the five observed years. The resulting productivity change is an average decrease of TFP (9%) over the period 2008-2012.

description: We present a numerical analysis supporting the evidence that the redshift evolution of the drifting coefficient of the field cluster mass function is capable of breaking several cosmic degeneracies. This evidence is based on the data from the CoDECS and DUSTGRAIN-pathfinder simulations performed separately for various non-standard cosmologies including coupled dark energy, $f(R)$ gravity and combinations of $f(R)$ gravity with massive neutrinos as well as for the standard $Λ$CDM cosmology. We first numerically determine the field cluster mass functions at various redshifts in the range of $0\le z\le 1$ for each cosmology. Then, we compare the analytic formula developed in previous works with the numerically obtained field cluster mass functions by adjusting its drifting coefficient, $β$, at each redshift. It is found that the analytic formula with the best-fit coefficient provides a good match to the numerical results at all redshifts for all of the cosmologies. The empirically determined redshift evolution of the drifting coefficient, $β(z)$, turns out to significantly differ among different cosmologies. It is also shown that even without using any prior information on the background cosmology the drifting coefficient, $β(z)$, can discriminate with high statistical significance the degenerate non-standard cosmologies not only from the $Λ$CDM but also from one another. It is concluded that the evolution of the departure from the Einstein-de Sitter state and spherically symmetric collapse processes quantified by $β(z)$ is a powerful probe of gravity and dark sector physics.

description: The Web is ubiquitous, increasingly populated with interconnected data, services, people, and objects. Semantic web technologies (SWT) promote uniformity of data formats, as well as modularization and reuse of specifications (e.g., ontologies), by allowing them to include and refer to information provided by other ontologies. In such a context, multi-agent system (MAS) technologies are the right abstraction for developing decentralized and open Web applications in which agents discover, reason and act on Web resources and cooperate with each other and with people. The aim of the project is to propose an approach to transform "Agent and artifact (A&A) meta-model" into a Web-readable format with ontologies in line with semantic web formats and to reuse already existing ontologies in order to provide uniform access for agents to things.

description: We study the motion of spinning test particles in Kerr spacetime using the Mathisson-Papapetrou equations; we impose different supplementary conditions among the well known Corinaldesi-Papapetrou, Pirani and Tulczyjew's and analyze their physical implications in order to decide which is the most natural to use. We find that if the particle's center of mass world line, namely the one chosen for the multipole reduction, is a spatially circular orbit (sustained by the tidal forces due to the spin) then the generalized momentum $P$ of the test particle is also tangent to a spatially circular orbit intersecting the center of mass line at a point. There exists one such orbit for each point of the center of mass line where they intersect; although fictitious, these orbits are essential to define the properties of the spinning particle along its physical motion. In the small spin limit, the particle's orbit is almost a geodesic and the difference of its angular velocity with respect to the geodesic value can be of arbitrary sign, corresponding to the spin-up and spin-down possible alignment along the z-axis. We also find that the choice of the supplementary conditions leads to clock effects of substantially different magnitude. In fact, for co-rotating and counter-rotating particles having the same spin magnitude and orientation, the gravitomagnetic clock effect induced by the background metric can be magnified or inhibited and even suppressed by the contribution of the individual particle's spin. Quite surprisingly this contribution can be itself made vanishing leading to a clock effect undistiguishable from that of non spinning particles. The results of our analysis can be observationally tested.

description: In the sugarcane production in Sao Paulo it was found that between crops 2007/08 and 2011/12 there was economic loss, a fact that leads to the goal of the present study : answer why these producers still remain providing sugarcane. Apart from the traditional viability analysis, the study incorporated the Real Options Theory analysis, which includes managerial flexibility on the investor decision model. Two sugarcane investment projects based on available information of Piracicaba and Sertãozinho regions were analyzed. Considering the discounted cash flow method, we obtained estimates pointing to the economic attractiveness of sugarcane planting in both regions, as shown by the positive response of the Net Present Values calculated. This evidence was corroborated when using the Real Options Theory, which incorporates flexibility on the decision model. Price and quality of sugarcane and agricultural productivity presented the higher impact on the financial viability of projects. Actions focused on agricultural productivity gains are seen as motivating for financial gain, while in terms of public policy we mention the possibility of adjustments in C gasoline pricing systems and in the taxation on sugarcane byproducts.

description: In the countries of Latin America, including Brazil, the levels of losses in the post-harvest stages of agricultural products is higher than that observed for more developed countries. The present study estimated the impacts of reduction in post-harvest losses of agricultural products to levels observed in countries of high income. We calculated this reduction and, using the input-output matrix of Brazil, estimated the impacts that this drop in losses could have on the Brazilian economy. These impacts are due to the increase in the following services: processing, transportation and trade, which would be included in those products recovered. The reduction in post-harvest losses would imply an increase of R$ 9.8 billion in the value of agricultural production (in 2012 values). In addition, it can be seen that the direct, indirect and income effects of an increase in demand for services (processing, transport and trade) caused by the increase of supply, can raise the value of output of the economy in R$ 18 billion, the country’s GDP in R$ 9.7 billion and generate more than 300,000 jobs. These results illustrate that, in view of the great importance of agricultural products for the Brazilian economy, the reduction in losses after harvest can generate substantial economic benefits for the country.

title: Connectionist Modelling of Category Learning
Creators: name: Bartos, Paul D.
Publisher: name: The Open University
Year: 2002

description: A shortcoming is identified with respect to the ability of exemplar-based connectionist models of category learning to offer accounts of learning about stimuli with variable dimensionality. Models which may simulate these tasks, such as the configural-cue network (Gluck & Bower, 1988b), appear to be unable to accurately simulate certain data well simulated by exemplar-based models such as ALCOVE (Kruschke, 1992). A task in which the advantage of ALCOVE is exemplified is the prediction of human learning rates on the six category structures tested by Shepard, Hovland, and Jenkins (1961). The ability of ALCOVE to simulate the observed order of difficulty depends on its incorporation of selective attention processes (Nosofsky, Gluck, Palmeri, McKinley, & Glauthier, 1994). This thesis focuses on developing configural-cue network models which incorporate these processes. Informed by an information-theoretic approach to modelling the implementation of selective attention using a configural-cue representation, five connectionist models are developed. Each is capable of predicting the order of difficulty reported by Shepard et al. (1961). Two models employ a modular structure, but analysis suggests that these may lack much of the functionality of the basic configural-cue network. The remaining three incorporate dimensional attention schemes. These models appear to offer superior generalisability in relation to the simulation of learning about variable dimensionality stimuli. This generalisability is examined by applying a variant of one of these dimensional attention models, to data collected by Kruschke (1996a) on the inverse base-rate effect and base-rate neglect. The model provides a qualitative fit to this data. The success of these configural-cue models on these two tasks, only successfully modelled previously using two distinct types of representation, indicates that the approach has some potential for further applications. Differences between the models applied, however, indicates that more sophisticated conceptions of the attention process may be required to allow further generalisability..

description: Doppler orbitography uses the Doppler shift in a transmitted signal to determine the orbital parameters of satellites including range and range-rate (or radial velocity). We describe two techniques for atmospheric-limited optical Doppler orbitography measurements of range-rate. The first determines the Doppler shift directly from a heterodyne measurement of the returned optical signal. The second aims to improve the precision of the first by suppressing atmospheric phase noise imprinted on the transmitted optical signal. We demonstrate the performance of each technique over a 2.2 km horizontal link with a simulated in-line velocity Doppler shift at the far end. A horizontal link of this length has been estimated to exhibit nearly half the total integrated atmospheric turbulence of a vertical link to space. Without stabilisation of the atmospheric effects, we obtained an estimated range rate precision of 17 um/s at 1 s of integration. With active suppression of atmospheric phase noise, this improved by three orders-of-magnitude to an estimated range rate precision of 9.0 nm/s at 1 second of integration, and 1.1 nm/s when integrated over a 60 s. This represents four orders-of-magnitude improvement over the typical performance of operational ground to space X-Band systems in terms of range-rate precision at the same integration time. The performance of this system is a promising proof of concept for coherent optical Doppler orbitography. There are many additional challenges associated with performing these techniques from ground to space, that were not captured within the preliminary experiments presented here. In the future, we aim to progress towards a 10 km horizontal link to replicate the expected atmospheric turbulence for a ground to space link.

Natural gas combustion under engine-relevant conditions
Creators: name: Huang, Jian
Publisher: name: University of British Columbia
Year: 2010

description: This thesis focuses on the study of natural gas combustion under engine relevant conditions. The work begins with the development of a detailed chemical kinetic mechanism that represents the ignition characteristics of methane with various minor additives over a wider range of operating conditions than previously existing mechanisms. The mechanism includes a NOx submechanism selected from the literature that yields good agreement with experimental data in various methane/air combustion systems. The excessive computational load associated with detailed chemistry is alleviated using a trajectory generated low-dimensional manifold (TGLDM) method. The TGLDMs generated in this work provide a satisfactory approximation of calculation using detailed chemistry in various methane/air reaction systems with a significant reduction of the computational cost. An innovative combustion model for simulating turbulent diffusion flames is presented at the end of this thesis. The model employs the Conditional Source-term Estimation method for the closure of the chemical source term. It obtains production/consumption rates of reaction scalars through TGLDMs generated with the new reaction mechanism. The model was used to simulate ignition and combustion of transient turbulent methane jets under engine-relevant conditions; it has achieved encouraging results in comparison with the experimental data from this work as well as the literature.

description: O artigo analisou a evolução das condições de vida das famílias dos empregados na agricultura brasileira no período 1992-2004, com base nos dados da Pesquisa Nacional por Amostra de Domicílios (Pnad). Para a análise, um Índice de Condições de Vida (ICV) foi elaborado a partir de 17 indicadores selecionados, de forma a mensurar quatro dimensões de grande relevância no cotidiano das famílias: as características do domicílio; o acesso aos serviços públicos; o acesso aos bens duráveis; e a renda média familiar. Para a determinação dos fatores de ponderação do ICV foi usado o método multicritério Macbeth. Os resultados mostraram que houve avanços em, praticamente, todos os tipos de famílias agrícolas, em todas as regiões. Os maiores ICVs foram registrados, no geral, para as famílias urbanas e de empregados permanentes. Em oposição, os ICVs mais baixos eram os das famílias rurais e de empregados temporários. ---- The article analyzed the evolution of life conditions of the employees' families in Brazilian agriculture in the period 1992-2004, based on the National Household Sample Survey (Pnad) data. For the analysis, a Life Conditions Index (LCI) was built assembling 17 selected indicators, in order the measure four relevant dimensions in the families’ daily life: the households’ characteristics; the access to public services; the access to durable goods; and the family average income. The Macbeth approach was used to calculate de LCI’s weights. The results showed that progresses took place in practically all the types of agricultural families in all the Regions. The la rgest LCIs were regist ered for urban families and families of permanent employees. In opposition, the lowest LCIs were the one of the rural families and families of temporary employees.

description: Future high spectroscopic resolution galaxy surveys will observe galaxies with nearly full-sky footprints. Modeling the galaxy clustering for these surveys, therefore, must include the wide-angle effect with narrow redshift binning. In particular, when the redshift-bin size is comparable to the typical peculiar velocity field, the nonlinear redshift-space distortion (RSD) effect becomes important. A naive projection of the Fourier-space RSD model to spherical harmonic space leads to diverging expressions. In this paper we present a general formalism of projecting the higher-order RSD terms into spherical harmonic space. We show that the nonlinear RSD effect, including the fingers-of-God (FoG), can be entirely attributed to a modification of the radial window function. We find that while linear RSD enhances the harmonic-space power spectrum, unlike the three-dimensional case, the enhancement decreases on small angular-scales. The fingers-of-God suppress the angular power spectrum on all transverse scales if the bin size is smaller than $Δr \lesssim πσ_u$; for example, the radial bin sizes corresponding to a spectral resolution $R=λ/Δλ$ of a few hundred satisfy the condition. We also provide the flat-sky approximation which reproduces the full calculation to sub-percent accuracy.

description: In this review, we provide an up-to-date account of quantitative holographic descriptions of the strongly coupled quark-gluon plasma (QGP) produced in heavy-ion collisions, based on the class of gauge-gravity Einstein-Maxwell-Dilaton (EMD) models. Holography is employed to tentatively map the QCD phase diagram at finite temperature onto a dual theory of charged, asymptotically AdS black holes in 5D. With a quantitative focus on the hot QCD phase diagram, the EMD models reviewed are adjusted to describe lattice results for the finite-temperature QCD equation of state, with 2+1 flavors and physical quark masses, at zero chemical potential and vanishing electromagnetic fields. The predictive power of EMD models is tested by quantitatively comparing their predictions for the hot QCD equation of state at nonzero baryon density and the corresponding state-of-the-art lattice QCD results. The shear and bulk viscosities predicted by these EMD models are also compared to the corresponding profiles favored by the latest phenomenological multistage models describing different heavy-ion data. We report preliminary results from a Bayesian analysis which provide systematic evidence that lattice results at finite temperature and zero baryon density strongly constrains the free parameters of EMD models. Remarkably, the set of parameters constrained by lattice results at zero chemical potential produces EMD models in quantitative agreement with lattice QCD results also at finite baryon density. We also review results for equilibrium and transport properties from magnetic EMD models, describing the QGP at finite temperatures and magnetic fields. Finally, we provide a critical assessment of the main limitations and drawbacks of the holographic models reviewed in the present work, and point out some perspectives we believe are of fundamental importance for future developments.

description: Galaxy interactions/mergers, gravitational instabilities and density waves, such as bars, are frequently invoked to trigger starbursts. These mechanisms have been explored through numerical simulations, with the help of various star formation recipes. Gravitational instabilities are necessary to initiate star formation, but the main trigger might be the gas flows, to provide sufficient fuel in a short time-scale. Gas accretion is also acting on the dynamics, in favoring bars/spirals, which will drive the gas inwards. Large amounts of external gas accretion are required to explain the bar frequency, and this accretion rate can be provided by the cosmic filaments, as supported by cosmological simulations. Subsequent interactions can then trigger starbursts by driving this accreted gas inwards.

description: We run three-dimensional numerical simulations for the accretion flow around the white dwarf (WD) in the progenitor system of Tycho's supernova (SN). The mass of the WD, mass of the companion star, and the orbital period are set to be 1$M_{\odot}$, 1.6$M_{\odot}$, and 0.794 day, respectively, based on theoretical and observational researches of Tycho's SN remnant (SNR). We find that when the magnetic field in the accreted material is negligible, outflowing wind is concentrated near the equatorial plane. When the magnetic field has energy equipartition with internal energy, polar wind is comparable with the equatorial wind. A carefully chosen magnetic field between the above two cases ($B=5.44\times10^3 \rm{G}$) can roughly reproduce the latitude-dependent wind required to form the peculiar periphery of Tycho's SNR.

description: Motivated by the recent experimental study on hydrogen storage in MXene multilayers [Nature Nanotechnol. 2021, 16, 331], for the first time we propose a workflow to computationally screen 23,857 compounds of MXene to explore the general relation between the activated H2 bond length and adsorption distance. By using density functional theory (DFT), we generate a dataset to investigate the adsorption geometries of hydrogen on MXenes, based on which we train physics-informed atomistic line graph neural networks (ALIGNNs) to predict adsorption parameters. To fit the results, we further derived a formula that quantitatively reproduces the dependence of H2 bond length on the adsorption distance from MXenes within the framework of Pauling's resonating valence bond (RVB) theory, revealing the impact of transition metal's ligancy and valence on activating dihydrogen in H2 storage.

description: O texto analisou a evolução das condições de saúde e do acesso aos serviços de saúde para uma categoria específica de ocupados na agricultura brasileira, que são os empregados agrícolas permanentes e temporários, tendo como base os microdados que foram tabulados dos suplementos especiais de saúde contidos nas Pnads de 1998 e 2003. De forma mais específica, o texto abordou as diferenças regionais quanto à evolução do perfil populacional no tocante à auto-avaliação do estado de saúde das pessoas, às restrições das atividades habituais, às principais doenças crônicas informadas, ao acesso e a utilização dos serviços de saúde, à cobertura dos planos de saúde e odontológico e à participação do SUS no atendimento da população trabalhadora. Em linhas gerais, os dados quantitativos mostraram uma evolução relativamente favorável do quadro de saúde dos empregados. As principais diferenças regionais se manifestaram nos indicadores de cobertura dos planos de saúde e de atendimento odontológico, sendo os empregados agrícolas das regiões Norte e Nordeste os menos assistidos. ---- The text analyzed the evolution of health conditions and health services access for a specific category of the Brazilian agricult ure employees: the permanent and temporary agricultural employees, based on the 1998 and 2003 Pnads micro data, tabulated from special health tables. In a specific approaching, the text deals with the evolution of the regional differences in the population profile concerning to the self-evaluation of the people's health condition, to the restrictions of people’s habitual activities, to the main chronic diseases information, to the access and use of the health services, to the health and dental plans coverage and to the participa tion of SUS in the workers’ attendance. The quantitative data point out a relatively favorable evolution in the employees' general health condition. The main regional differences refer to the indexes of health and dental plans coverage, and the less attended agricultural employees live in the North and Northeast regions.

description: Two phase solid-fluid mixture models are ubiquitous in biological applications. For instance, models for growth of tissues and biofilms combine time dependent and quasi-stationary boundary value problems set in domains whose boundary moves in response to variations in the mechano-chemical variables. For a model of biofilm spread, we show how to obtain better posed models by characterizing the time derivatives of relevant quasi-stationary magnitudes in terms of additional boundary value problems. We also give conditions for well posedness of time dependent submodels set in moving domains depending on the motion of the boundary. After constructing solutions for transport, diffusion and elliptic submodels for volume fractions, displacements, velocities, pressures and concentrations with the required regularity, we are able to handle the full model of biofilm spread in moving domains assuming we know the dynamics of the boundary. These techniques are general and can be applied in models with a similar structure arising in biological and chemical engineering applications.

description: We develop a Hamiltonian theory for a time dispersive and dissipative (TDD) inhomogeneous medium, as described by a linear response equation respecting causality and power dissipation. The canonical Hamiltonian constructed here exactly reproduces the original dissipative evolution after integrating out auxiliary fields. In particular, for a dielectric medium we obtain a simple formula for the Hamiltonian and closed form expressions for the energy density and energy flux involving the auxiliary fields. The developed approach also allows to treat a long standing problem of scattering from a lossy non-spherical obstacle and, more generally, wave propagation in TDD media.

description: Numerical Weather Models are among the most used tools by forecasters nowadays. However, the numerical output in the form that is delivered by the model, does not reveal all the information needed to prepare a weather forecast report. Hence, there is a need to derive products from these outputs that allow for instance: identification of meteorological phenomena, rainfall area, and others; all of which will enable the generation of automatic reports on its evolution and movement, and the validation with real data. The present paper aims to accomplish this goal. We describe the first version of the detection, report and evaluation module that will be coupled with the short-range forecast system being developed in the Institute of Meteorology of Cuba. As a result, a post-processing tool is developed composed by algorithms for detection of hurricanes, cold fronts, rainfall areas and cloudiness in model outputs; which can be monitored, and validated with satellite images. Ridge method, convolution and fuzzy logic are among the algorithms that we have used here.

description: The nonlinear force-free field (NLFFF) modeling has been extensively used as a tool to infer three-dimensional (3D) magnetic field structure. In this study, the dependency of the NLFFF calculation with respect to the initial guess of the 3D magnetic field is investigated. While major part of the previous studies used potential field as the initial guess in the NLFFF modeling, we adopt the linear force-free fields with different constant force-free alpha as the initial guesses. This method enables us to investigate how unique the magnetic field obtained by the NLFFF extrapolation with respect to the initial guess is. The dependence of the initial condition of the NLFFF extrapolation is smaller in the strong magnetic field region. Therefore, the magnetic field at the lower height ($< 10$ Mm) tends to be less affected by the initial condition (correlation coefficient C>0.9 with different initial condition), although the Lorentz force is concentrated at the lower height.
