Improving Monocular Depth Estimation using auxiliary information
Creators: name: Auty, Dylan
Publisher: name: Imperial College London
Year: 2024

description: Monocular Depth Estimation (MDE) is the problem of estimating the distance from the camera to every part of the scene shown in a single input image. It is challenging due to its inherent ambiguity, but Deep Learning (DL) methods perform well, typically by learning to interpret their inputs implicitly by minimising prediction error. However, this approach hides a significant weakness: the model must waste limited capacity, training data, and computation on discovering what parts of the input are important, before it can learn to interpret them. This work addresses this inefficiency, answering the question: how can auxiliary information, sourced from outside the training data, be used to improve MDE performance? Biological depth cues are shown to be useful in a DL context. Then, a novel module is proposed that encourages the model to focus on inter-object relationships. Language models are investigated as a source of object semantics, and are shown to improve performance. A prompt learning technique is proposed that uses a joint vision-and-language model to directly predict depth. The learned prompts are found not to map to depth-related words, implying that human language is inadequate for describing depth. Cross-task knowledge distillation is investigated to provide implicit knowledge to an MDE model. A method is proposed that effectively transfers knowledge from teachers trained for non-MDE tasks, and is extended to a novel teacher-free loss. The proposed methods successfully leverage auxiliary information from biological depth cues, auxiliary semantic models, human language, and the latent space of non-MDE models to improve MDE performance. The success of the various methods presented show that the fully implicit, end-to-end paradigm must be revised to obtain optimal MDE performance, and avenues for possible future work are discussed.

description: Nos últimos anos a agricultura familiar passou a usufruir de maior atenção e destaque por parte dos programas governamentais, mormente pelo Programa Nacional de Fortalecimento da Agricultura Familiar (Pronaf), e mais atualmente pelo Programa Nacional de Produção e Uso do Biodiesel (PNPB). Contudo os gargalos relativos à infra-estrutura logística e os demais custos relativos à cadeia de biodiesel podem tornar vantajoso economicamente para as indústrias produzir seus próprios insumos, ou mesmo os adquirirem dos grandes produtores rurais. Tendo em vista essa possibilidade foi utilizado o ferramental da Análise Exploratória de Dados Espaciais (AEDE), como forma de verificar como as variáveis rendimento médio de óleo vegetal advindo da agricultura familiar (insumos), produção efetiva de biodiesel, e malha rodoviária total (estrutura logística) se relacionaram durante o ano de 2005. Usando as técnicas de análise espacial bivariada, os resultados revelam que todas as interações espaciais globais são positivas e significativas, mas existem diferenças quando se investiga padrões locais por meio da emergência de agrupamentos espaciais. -------------------------Over last years the familiar agriculture has received more attention by public policies, as in the National Program of Strenghtening of familiar agriculture and in the National Program of production and use of biodiesel. However the obstacles referring to logistics and the other costs related to biodiesel system may get advantageous in economic terms for industries to produce their own inputs or even to buy from big rural farmers. Having this in mind, the exploratory spatial data analysis (ESDA) is adopted by verifying as the variables such as average receipt, biodiesel output and transport network relate each other during the year 2005. Using the bivariate spatial analysis techniques, the findings reveal all global spatial interactions are positive and significant, but there are differences when investigating local patterns by means of emerging of spatial clusters.

description: Este trabalho objetivou analisar as mudanças ocorridas na despesa com água e esgoto, em resposta à alteração na renda das famílias nas regiões Norte, Nordeste, Centro-Oeste, Sudeste e Sul. Para isso, estimou-se a elasticidade-renda da despesa por meio de um modelo econométrico que consiste em ajustar uma poligonal com três segmentos, com vistas em mostrar como a despesa com água e esgoto varia em decorrência de uma alteração no recebimento familiar. Os dados foram extraídos da Pesquisa de Orçamento Familiar de 2002/2003, realizada pelo IBGE. Os valores encontrados para elasticidade-renda situaram-se entre 0 e 1, o que indica que a água pode ser considerada um bem normal nas regiões analisadas e no Brasil, onde o valor encontrado foi de 0,4263. As estimativas mostraram ainda que, quase sempre, a elasticidade-renda das despesas com água e esgoto no meio rural é maior do que no meio urbano.----------------------The objective of this paper was to analyze the expense changes with water and sanitation taxes in response to change in households’ income in the main Brazilian regions (North, Northeast, Central-West, South East, and South). The data were collected from the Household Budgetary Research (POF) of IBGE for the period 2002/2003. Elasticity-income of expenditure was estimated through an econometric model which consisted of an adjusted polygonal with three segments. The values encountered for the elasticity-income of expenditure are between 0 and 1, indicating that water can be considered a normal good in the regions analyzed, and, for the country as a whole, the value encountered was 0.4263. The estimations show also that, in general, the elasticity-income of expenditure of water and sanitation taxes is higher in rural areas than in urban areas.

Mais especificamente, a análise terá como foco as diferenças existentes entre as famílias das áreas urbanas e rurais do país, nos anos de 1995 e 2006. A hipótese central é de que as aposentadorias e pensões cumprem importante papel no rendimento das famílias mais pobres e das áreas rurais, contribuindo principalmente para a redução da pobreza nas regiões mais precárias do país. Esta dependência teria ainda aumentado no período analisado devido, sobretudo, à vinculação dos rendimentos de aposentaria e pensão ao salário mínimo e aos ganhos reais observados por este no período.------------------------This papers analyzes the impacts of retirement pensions on poverty reduction in Brazil. More specifically, the analyzes will focus the differences among families from urban and rural areas in this country, between 1995 and 2006. The central hypothesis is that the retirement pensions play an important role on the income of poorest families and those from rural areas, contributing mainly to poverty reduction in the most precarious Brazilian regions. This relationship had grown in this period due to the link between retirement pensions and minimum wage and the real increases witnessed by the minimum wage in this period.

description: Post-Newtonian expansions of the binding energy and gravitational wave flux truncated at the {\it same relative} post-Newtonian order form the basis of the {\it standard adiabatic} approximation to the phasing of gravitational waves from inspiralling compact binaries. Viewed in terms of the dynamics of the binary, the standard approximation is equivalent to neglecting certain conservative post-Newtonian terms in the acceleration. In an earlier work, we had proposed a new {\it complete adiabatic} approximant constructed from the energy and flux functions. At the leading order it employs the 2PN energy function rather than the 0PN one in the standard approximation, so that, effectively the approximation corresponds to the dynamics where there are no missing post-Newtonian terms in the acceleration. In this paper, we compare the overlaps of the standard and complete adiabatic templates with the exact waveform in the adiabatic approximation of a test-mass motion in the Schwarzschild spacetime, for the VIRGO and the Advanced LIGO noise spectra. It is found that the complete adiabatic approximants lead to a remarkable improvement in the {\it effectualness} at lower PN ($

description: O processo de reconhecimento dos agricultores familiares como sujeitos de direitos apesar de ser recente quando pensado a partir da trajetória do sindicalismo rural brasileiro demonstra ter suas primeiras raízes ainda na constituição da legislação trabalhista-sindical dos anos de 1930. Visando explorar esse processo o artigo tem por objetivo analisar a emergência dos agricultores familiares como sujeitos de direitos na sociedade brasileira contemporânea. Analisa-se os processos de formação do sindicalismo rural e de expansão da legislação trabalhista para os trabalhadores rurais como forma de realização de uma “cidadania regulada” até a década de 1970; o questionamento do sindicalismo oficial, a estruturação de um “novo sindicalismo” e a emergência de novos atores sociais no campo, que possibilitaram a ampliação dos espaços de cidadania no período de redemocratização do Brasil; a “crise” do novo sindicalismo, a criação de novas estruturas sindicais “por fora” da estrutura oficial (sindicalismo da agricultura familiar) e a emergência dos “agricultores familiares” como sujeitos de direitos no período recente.-------------------------The process of the family farmers' recognition as individuals with rights demonstrates having their first roots, in spite of being recent, if compared to the history of the Brazilian rural syndicalism, still in the constitution of the labor-syndical legislation in 1930.

Peak Effect in Superconductors: Absence of Phase Transition and Possibility of Jamming in Vortex Matter

description: The magnetic field $B$ dependence of the critical current $I_c$ for the vortex phase of a disordered superconductor is studied numerically at zero temperature. The $I_{c}(B)$ increases rapidly near the upper critical field $B_{c2}$ similar to the peak effect (PE) phenomenon observed in many superconductors. The real space configuration across the PE changes continuously from a partially ordered domain (polycrystalline) state into an amorphous state. The topological defect density $n_{d}(B)\sim e^{αB^{k}}$ with $k>1$ for $B\geq 0.4B_{c2}$. There is no evidence of a phase transition in the vicinity of the PE suggesting that an order-disorder transition is not essential for the occurrence of the PE phenomenon. An alternative view is presented wherein the vortex system with high dislocation density undergoes jamming at the onset of the PE.

Rapid computational screening of materials for energy storage applications
Creators: name: Onwuli, Anthony
Publisher: name: Imperial College London
Year: 2024

description: Energy storage systems are vital for enabling the distribution and storage of renewable energy and the development of electric vehicles. Solid-state electrolytes will be key to scaling up the development of safe batteries for this application. Computational materials design enables us to discover new materials at a lower cost and in a shorter timeframe than an Edisonian experimental synthesis approach. In the first results chapter of this thesis (Chapter 4), the concept of quantifying the search space of stoichiometric garnets is presented using structure substitutions and a geometric descriptor for phase stability. Following this was a high-throughput density functional theory screening to determine the phase stability of these compounds. In Chapter 5, the high-throughput materials design workflow previously introduced is leveraged for the discovery of novel sodium halide electrolyte materials. A large compositional space of 3,710 quaternary materials was screened and the phase, electrochemical, and interfacial stability, as well as the Na-ion diffusivity, were analysed through a mixture of high-throughput DFT calculations and machine-learning molecular dynamic simulations. The work described in Chapter 6 delved more into materials informatics in which high-dimensional representations of the chemical elements were analysed to see if they reproduce chemical trends and show potential applications for structure substitution based on chemical similarity. To end this thesis, in the final results chapter (Chapter 7), the concept of machine learning representations of compounds was expanded upon by designing of ionic representations which were proven to enhance structure-agnostic learning for properties derived from the electronic structure such as the band gap. Many of the results and ideas presented in this thesis may pave the way for the potential design of new materials, but more broadly aim to synthesise many of the methods for materials informatics and materials modelling and extend their application into both functional and novel applications.

The Fraser Basin Council’s role as a facilitating institution in the consensus-based development of the Fraser River Management Plan
Creators: name: Lapp, Laura Mitchelle
Publisher: name: University of British Columbia
Year: 2009

description: Facilitated consensus-based processes seek to develop constructive dialogue and collaborative opportunities among stakeholders and thus have the potential to improve problem identification and decision-making. This thesis assesses the ability of the Fraser Basin Council (Council) to contribute to the procedural success of a consensus-based process as a facilitating institution. A "facilitating institution", a concept not documented in the literature, is defined as a non-partisan institution that draws on its membership to facilitate consensus-building on issues related to a common interest. In the case of the Council, it is a unique institution constituted of government, private sector and public representatives that focuses on economic, environmental and social sustainability goals. In the absence of performance measures to assess such an institution, a twopart analytical framework is developed which first outlines six performance measures associated with successful consensus-based processes, with an emphasis on "Agreement on the Facilitator". It identifies several factors that influence the facilitating institution's ability to assist the participants in achieving success. In particular, qualities the institution adds to or detracts from the process, the style of intervention it uses and how its performance compares to a set of strengths and weaknesses of facilitating institutions. The "Fraser River Management Plan: Hope to Mission" (FRMP) process is used as a case study. A qualitative research approach employs document analysis and semi-structured interviews with a cross-section of FRMP process participants, Council staff and Directors. The participants' assessment of the FRMP process results in performance measure ratings that are highly positive for "Agreement on the Facilitator" and "Representation of Interest", positive for "Interest-Driven Framework" and "Informed Decision-Making", mixed for "Clarity of Process" and negative for "Decision Implementation". Conclusions on the Council's facilitation of the FRMP process are that (1) the influence of the Council was most positive at the "front end" of the process, (2) the Council has considerable potential as a facilitating institution, not all of which was maximized and (3) the role of the Council as a facilitating institution needs to be defined more explicitly and communicated to the broader public.

description: We examine whether the Mott transition of a half-filled, two-orbital Hubbard model with unequal bandwidths occurs simultaneously for both bands or whether it is a two-stage process in which the orbital with narrower bandwith localizes first (giving rise to an intermediate `orbital-selective' Mott phase). This question is addressed using both dynamical mean-field theory, and a representation of fermion operators in terms of slave quantum spins, followed by a mean-field approximation (similar in spirit to a Gutzwiller approximation). In the latter approach, the Mott transition is found to be orbital-selective for all values of the Coulomb exchange (Hund) coupling J when the bandwidth ratio is small, and only beyond a critical value of J when the bandwidth ratio is larger. Dynamical mean-field theory partially confirms these findings, but the intermediate phase at J=0 is found to differ from a conventional Mott insulator, with spectral weight extending down to arbitrary low energy. Finally, the orbital-selective Mott phase is found, at zero-temperature, to be unstable with respect to an inter-orbital hybridization, and replaced by a state with a large effective mass (and a low quasiparticle coherence scale) for the narrower band.

description: The problem of comparison of the stationary axisymmetric vacuum solutions obtained within the framework of exact and approximate approaches for the description of the same general relativistic systems is considered. We suggest two ways of carrying out such comparison: (i) through the calculation of the Ernst complex potential associated with the approximate solution whose form on the symmetry axis is subsequently used for the identification of the exact solution possessing the same multipole structure, and (ii) the generation of approximate solutions from exact ones by expanding the latter in series of powers of a small parameter. The central result of our paper is the derivation of the correct approximate analogues of the double-Kerr solution possessing the physically meaningful equilibrium configurations. We also show that the interpretation of an approximate solution originally attributed to it on the basis of some general physical suppositions may not coincide with its true nature established with the aid of a more accurate technique.

description: Esse trabalho teve como objetivo verificar a viabilidade financeira da implementação de um sistema automatizado de irrigação por miniaspersão na cultura do feijão. O trabalho toma como referência a teoria de análise financeira de investimentos, considerando a abordagem determinística e probabilística. Os dados relativos à produtividade do feijoeiro, ao sistema de irrigação por miniaspersão, bem como os coeficientes técnicos, os custos de produção e as receitas de venda foram baseados em experimentos e coletas de dados realizados por pesquisadores da UFV. Diante dos resultados, pode-se concluir que tanto nos cenários determinístico e probabilístico, o projeto de irrigação por miniaspersão na cultura de feijão apresenta-se viável. O projeto é consideravelmente sensível às alterações nas variáveis de risco, a exemplo do preço dos fatores de produção e do custo de oportunidade do capital. Dentre esses fatores maior sensibilidade foi observada nas variações de preço do feijão. ---------------------------------------------This study was conducted to verify the financial viability for implementation of an automated microsprinkler irrigation system in the bean crop. The theory of the financial investment analysis is taken as reference, by considering both deterministic and probabilistic approaches. The data concerning to productivity of the bean plant under the microsprinkler irrigation, as well as the technical coefficients, production costs and sales revenue were based on the experiments and data collection accomplished by the UFV researchers. According to the results, it is concluded that the microsprinckler irrigation project for bean crop is viable in both deterministic and probabilistic sceneries. The project is considerably sensible to alterations in the risky variables, such as the price of the production factors and the capital opportunity cost. A higher sensibility was observed in variations of the bean price.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: O presente trabalho consiste em um estudo realizado com objetivo principal de avaliar o impacto do aumento na capacidade de armazenagem de soja na propriedade rural, sobre o nível de preços da commodity e deste sobre a viabilidade de novos incrementos na capacidade de armazenagem. Para o seu desenvolvimento aplicou-se um estudo exploratório, baseado no levantamento e análise de dados relacionados ao comportamento da oferta e dos preços da soja em nível mundial e os montantes a serem investidos na instalação de sistemas de armazenagem com diferentes capacidades. A partir da elasticidade-preço da oferta mundial de soja em grão e da participação brasileira no mercado mundial da commodity, foram propostos seis diferentes cenários com diferentes níveis de capacidade de armazenagem da soja nas propriedades rurais brasileiras. Como principais resultados, observou-se que na medida em que a capacidade de armazenagem aumenta, os preços mundiais tendem a se elevar, podendo gerar ganhos superiores a R$5,00/saca para o produtor em um cenário onde a capacidade de armazenagem chegue a 60% da produção. Observou-se também, que estes ganhos refletem em reduções significativas nos paybacks dos investimentos em estocagem, demonstrando que uma ação inicial poderá gerar ganhos contínuos. ----------------------------------------------The present paper consists of a study accomplished with main objective of evaluating the impact of the increase in the capacity of soybean storage in the farms, on the level of the commodity prices and of prices on the viability of new increments in the storage capacity. An exploratory study was applied, based on survey and analysis of data related to the behavior of the supply and of the prices of the soybean in world level and the amounts to be invested in the installation of storage systems with different capacities. Starting from the elasticity-price of the world supply of soybean in grain and of the Brazilian participation in the world market of the commodity, six different scenarios were proposed with different levels of capacity of storage of the soybean in the Brazilian farms. As main results, it was observed that when the storage capacity increases, the world prices tend rising, could generate gains bigger then R$2,50/bushel to producer in a scenario where the storage capacity arrives to 60% of the brazilian production. It was also observed, that these earnings contemplate in significant reductions in the paybacks of the investments in stockpiling, demonstrating that an initial action can generate continuous gains.

description: In this paper the path integral technique is applied to the quantum motion on the Hermitian hyperbolic space HH(2). The Schrödinger equation on this space separates in 12 coordinate systems which are closely related to the coordinate systems on the two-dimensional hyperboloid. For six coordinate systems out of the twelve it is possible to find a path integral solution.

description: Purpose: To develop a synergistic image reconstruction framework that exploits multicontrast (MC), multicoil, and compressed sensing (CS) redundancies in magnetic resonance imaging (MRI). Approach: CS, MC acquisition, and parallel imaging (PI) have been individually well developed, but the combination of the three has not been equally well studied, much less the potential benefits of isotropy within such a setting. Inspired by total variation theory, we introduce an isotropic MC image regularizer and attain its full potential by integrating it into compressed MC multicoil MRI. A convex optimization problem is posed to model the new variational framework and a first-order algorithm is developed to solve the problem. Results: It turns out that the proposed isotropic regularizer outperforms many of the state-of-the-art reconstruction methods not only in terms of rotation-invariance preservation of symmetrical features, but also in suppressing noise or streaking artifacts, which are normally encountered in PI methods at aggressive undersampling rates. Moreover, the new framework significantly prevents intercontrast leakage of contrast-specific details, which seems to be a difficult situation to handle for some variational and low-rank MC reconstruction approaches. Conclusions: The new framework is a viable option for image reconstruction in fast protocols of MC parallel MRI, potentially reducing patient discomfort in otherwise long and time-consuming scans.

description: 3D printing technology  enables the creation of complex internal structures within elements. This research introduces the use of a bio-inspired 3D infill pattern, the Gyroid, to fill the inner space of plastic cylinders. Mechanical properties were analyzed under varying unit cell sizes and infill densities using compression tests combined with Digital Image Correlation (DIC) systems, and these results were compared to references using 2D infill patterns.  Local stiffness was investigated based on the symmetry of infill patterns, providing a quantitative measure of stiffness. Global stiffness was determined by analyzing the distribution of elastic modulus within representative sections. The mean value of global stiffness was used for comparison with other elements, while the standard deviation indicated the homogeneity of stiffness. Strength characteristics were also assessed.  Our findings reveal that increasing infill density from 20% to 30% has a minimal impact on mechanical properties. Interestingly, in uniaxial compression tests, elements with 2D infill patterns exhibited higher stiffness and strength compared to those with 3D infill patterns. However, 3D infill patterns contributed to a more even distribution of elastic modulus, enhancing performance under complex loading scenarios. Furthermore, the combination of DIC systems allowed us to observe the deformation of the entire element during compression and study the rotation of the infill pattern. These results offer valuable insights for the selection and design of elements incorporating 3D-printed infill patterns, with potential applications in engineering and design.

description: Esse artigo utilizou testes de exogeneidade e de co-integração para determinar o poder de compra entre os segmentos de produtores agrícolas, atacado e varejo em São Paulo. Foram utilizadas séries de preços de arroz em nível de produtor de arroz no estado de São Paulo, preço de arroz no atacado e varejo, ambos na cidade de São Paulo. O período de análise abrange o período de janeiro de 1995 a dezembro de 2006. Os resultados mostram que, no longo prazo, o atacado deprime o valor recebido pelo produtor de arroz em 15,10% (elasticidade de transmissão de preço maior que a unidade), resultado que demonstra o poder de compra do primeiro sobre o segundo. Os resultados também mostram que o varejo deprime os preços do arroz no atacado no longo prazo, porém, com menor intensidade, cerca de 10,02% (elasticidade de transmissão de preço próximo da unidade). Ambos resultados refletem os efeitos das respectivas estruturas de comercialização do arroz.-----------------------------------------------This work used exogeneity and cointegration tests so as to determine the level of buyers’ power among wholesale and retail levels of agricultural production in Sao Paulo. We used series for rice prices at producer level in the state of Sao Paulo, as well as rice prices at wholesale and retail levels, both in the city of Sao Paulo between January 1995 and December 1996. Results showed that in the long run the wholesale level is able to depress by 15.10% (elasticity transmission more than one) the prices received by the producer, thus evidencing the buyers’ power of the wholesalers against producers. Results also showed that retailers are able to depress wholesale rice prices in the long run, although with lower intensity, by 10.02% (elasticity transmission near one). Both results are related to the underlying structures of rice trading.
