The advanced constitutive model KHSM for structured clays, which incorporates the effects of loss of structure within an elastoplastic framework, has been implemented in a finite element procedure and used to investigate the failure height and pore-water pressures of embankment A constructed at Saint Alban, Quebec. For the purpose of model comparison, simulations were also performed using the standard bubble model (KHM) without destructuration. The numerical predictions of pore-water pressures and settlements are also compared with field measurements. The results clearly demonstrate the importance of including the effects of loss of structure in the analysis.

Konsep branding pada universitas dapat memberikan reputasi yang baik untuk universitas baik dari segi pelayanan maupun fasilitas yang diberikan kepada para calon mahasiswanya. Namun, penelitian mengenai konsep branding tersebut di Indonesia masih relatif terbatas. Melalui aspek sosial, penelitian ini bertujuan untuk menyelidiki dampak nilai-nilai yang dirasakan mahasiswa Universitas Bangka Belitung (nilai utilitas, nilai hedonic dan relasional atau hubungan) terhadap Kualitas Hubungan Merek (KHM) dengan merek institusional Universitas Bangka Belitung (UBB) serta pada akhirnya pada resonansi merek (RM). Sejumlah 250 sampel yang berlokasi di Universitas Bangka Belitung dapat diambil secara online menggunakan teknik convenience sampling dan data tersebut dianaliskan melalui Persamaan Model Struktural (SEM). Hasil menunjukkan bahwa seluruh faktor prediktif dapat mempengaruhi secara positif terhadap KHM dan KHM dapat memediasi hubungan faktor-faktor prediktif dan RM. Dengan roadmap merek yang dirancang dengan baik, universitas dapat menurunkan masalah salah interpretasi oleh calon mahasiswa yang dapat menggagalkan upaya pengembangan citra merek universitas di masa depan. AbstractThe concept of branding at universities can provide a good reputation for universities both in terms of services and facilities provided to prospective students. However, research on the concept of branding in Indonesia is still relatively limited. Through social aspects, this study aims to investigate the impact of perceived values of Bangka Belitung University students (utility value, hedonic value, and relational value) on Brand Relationship Quality (BRQ) with the institutional brand of Bangka Belitung University (UBB) and finally in Brand Resonance (BR). A total of 250 samples located at Bangka Belitung University can be taken online using convenience sampling techniques and the data is analyzed through Structural Model Equations (SEM). The results show that all predictive factors can positively influence the BRQ and BRQ can mediate the relationship between predictive factors and RM. With a well-designed brand roadmap, universities can reduce the problem of misinterpretation by prospective students that can thwart efforts to develop the university's brand image in the future.

Abstract Introduction Kigamicin (KM) is a compound isolated from Actinomycetes, which reportedly induces necrosis in pancreatic cancer cells under nutrient-starving condition but not under nutrient rich condition via PI3-kinase inhibition (Lu et al., Cancer Science 95, 547–52, 2004). Although the PI3-kinase activity is thought to be critical in the growth of myeloma cells, its actual role remains to be determined. In the present study, we evaluated KM’s anti-myeloma activity in both laboratory and primary myeloma cells and found that, contrary to the original finding in pancreatic cancer cells, KM induced necrosis in human myeloma cells both under nutrient-starving and nutrient-rich conditions. Results and discussion Myeloma cell lines (12PE and KHM-11) and primary myeloma cells purified with CD138-coated immune-magnetic beads were incubated with KM under nutrient-rich conditions. The CC50 value of KM for myeloma cells was approximately 100 nM after 24-hour exposure while pancreatic cancer cell line, PANC-1, did not show inhibition of viability even at 10 mM under nutrient-rich conditions, suggesting high sensitivity of myeloma cells to KM. When whole mononuclear cells obtained from a myeloma patient’s bone marrow were cultured with KM at a concentration of 500 nM in vitro, normal lymphocytes were spared while all myeloma cells underwent necrosis, suggesting that preferential cytotoxicity of KM in myeloma cells. Western blot analysis revealed that AKT phosphorylation decreased with KM treatment, suggesting that KM inhibits PI-3 kinase activity as previously reported. However, another pan-PI3 kinase inhibitor, LY294002, did not induce necrosis in myeloma cells, suggesting that PI3-kinase inhibition is not critically related to the cytotoxicity of KM in myeloma cells. A pan-caspase inhibitor, ZVAD-FMK, only partially inhibited cell death, suggesting that caspase is not involved in the cytotoxic function of KM, either. To further determine the mechanism of cytotoxicity in myeloma cells, a possible involvement of cyclin D1 and p21 was also examined. Western blot analysis revealed that KM completely reduced cyclin-D1 in myeloma cells. Moreover, KM induced translocation of p21 from cytoplasm to nucleus within 5 hours treatment, suggesting that KM disrupted cell cycle regulation. Finally, melphalan-resistant myeloma cell line, 11-EMS, showed significant cell death when exposed to KM even more efficiently than did melphalan-sensitive parental cell line, KHM-11. Since a number of anti-cancer reagents induce apoptosis in myeloma cells, KM induction of necrosis may represent a unique mechanism(s) and may overcome drug resistance of myeloma cells. Taking into a consideration a recent report by Lu et al. (Cancer Science 95, 547–52, 2004) showing that KM’s safe usage in a murine pancreatic cancer xenograft model, the present data suggest that KM could be a potential therapeutic agent for treatment of myeloma and warrant that further preclinial development of KM be continued.

The master thesis deals with G.fast and G.mgfast transmission technologies, including their parameters. The work deals with the principle of vector DMT modulation and the possibility of time duplex TDD and full-duplex FDX in two-way communication used in these technologies. The following is a description of the line using the KHM model, which is suitable for simulations in the transmission band using G.fast and G.mgfast technologies. Subsequently, the disturbing effects of crosstalk at the near end of NEXT and the far end of FEXT and their elimination with these technologies are discussing. Part of the work explains supporting calculations to determine the SNR and bit allocation to calculate the baud rate. The work describes the methods of compensation of crosstalk FEXT and NEXT, which affect the resulting baud rate. The work also includes an application for simulation of transmission speed as a function of distance for G.fast and G.mgfast technologies, allowing changing input parameters and adjusting the transmission bandwidth based on G.9700 and G.9701 standards. Also, in work, an application is created to display the compensation of the influence of the transmitted signal crosstalk FEXT and NEXT, which allow the import of measured crosstalk between individual participants. The issue of influencing crosstalk for accurate measurements in the laboratory is also discussing. An application in the MATLAB environment is creating to display the measured characteristics.

L’objectif de ce travail est d’établir des résultats de rigidité spectrale pour des familles C1 d’opérateurs (pseudo-)différentiels elliptiques auto-adjoints Pt, t ϵ [0, ẟ] sur une variété lisse compacte M sans bord de dimension n ≥ 2. Dans les deux premiers chapitres, on étudie des hamiltoniens proches d’un hamiltonien intégrable qui est non dégénéré au sens de Kolmogorov (Système KAM). On y construit une forme normale de Birkhoff au voisinage de chaque tore KAM ayant une fréquence diophantienne. Dans les chapitres 3 et 4 on établit une forme normale de Birkfoff quantique afin de construire des familles C1 de quasi-modes. Ces dernières permettent de relier les propriétés spectrales de Pt aux propriétés dynamiques des tores KAM. Les deux derniers chapitres proposent des applications en lien avec la transformée de Radon ainsi qu’une étude sur les surfaces de rotation
The aim of this work is to obtain spectral rigidity results for C1 families of elliptic self-adjoint (pseudo-)differential operators Pt, t ϵ [0, ẟ], on a smooth closed manifold M of dimension n ≥ 2. In the first two chapters, we investigate Hamiltonians close to a given integrable Hamiltonian which is non-degenerate in the sense of Kolmogorov (KAM system). This allows us to obtain a Birkhoff normal form in a neighborhood of any KAM tori with a Diophantine frequency. In the third and fourth chapters, we construct a quantum Birkhoff normal form and obtain C1 families of quasimodes. Using the quasi-modes, we establish a connection between the spectral properties of Pt and the dynamical properties of the KAM tori. The last two chapters provide applications of these results to the Radon transform and the surfaces of revolution

Es wird eine selbstkonsistente, approximative L\"osung f\"ur das verd\"unnte, ungeordnete Kondo-Gitter-Modell (KLM) vorgeschlagen, um die miteinander verkn\"upften elektronischen und magnetischen Eigenschaften von sogenannten ''local moment''-Systemen wie den verd\"unnten magnetischen Halbleitern zu diskutieren. Untersucht werden Verbindungen der Form $A_{1-x}M_x$, in denen magnetische ($M$) und nicht-magnetische Atome ($A$) statistisch \"uber das Kristallgitter verteilt sind. Die Kopplung zwischen den lokalisierten Momente und den quasi-freien Elektronen (L\"ocher) wird im Rahmen einer modifizierten RKKY-Theorie behandelt, die das KLM auf ein effektives Heisenberg-Modell abbildet. Die Unordnungen in dem elektronischen Teilsystem und in dem magnetischen Momentensystem werden nach Methoden behandelt, die der ''coherent potential approximation'' (CPA) angepa{\ss}t sind. Es wird eine Erweiterung der CPA zur Berechnung der sich wechselseitig bedingenden elektronischen und magnetischen Eigenschaften verd\"unnter ''local moment''-Systeme vom Typ $A_{1-x}M_x$ f\"ur die Situation vorgeschlagen, in der eine durch Kristallfeldparameter bedingte Unordnung in der N\"{a}chste-Nachbar-Schale des Aufatoms ber\"ucksichtigt werden mu\ss. Dabei werden Kristallfeldparameter zwischen zwei nicht-magnetischen Atomen ($\lambda^{AA}$), zwischen einem magnetischen und einem nicht-magnetischen Atom ($\lambda^{AM}$) und zwischen zwei magnetischen Atomen ($\lambda^{MM}$) unterschieden. Schl\"usselgr\"o{\ss}en wie die langreichweitigen und oszillierenden effektiven Austauschintegrale und die Curie-Temperatur und die elektronischen und magnonischen Quasiteilchen-Zustandsdichten werden im Detail in Abh\"angigkeit der Konzentration $x$ der magnetischen Ionen, der Ladungstr\"ager-Konzentration $n$, der Interband-Austauschkopplung $J$, der Temperatur und der Kristallfeldparameter untersucht.
We propose a self-consistent approximate solution of the disordered Kondo-lattice model (KLM) to get the interconnected electronic and magnetic properties of ''local-moment'' systems like diluted ferromagnetic semiconductors. Aiming at $(A_{1-x}M_x)$ compounds, where magnetic (M) and non-magnetic (A) atoms are distributed randomly over a crystal lattice, we present a theory which treats the subsystems of itinerant charge carriers and localized magnetic moments in a homologous manner. The coupling between the localized moments due to the itinerant electrons (holes) is treated by a modified RKKY-theory which maps the KLM onto an effective Heisenberg model. The disordered electronic and magnetic moment systems are both treated by coherent potential approximation (CPA) methods. An extension of CPA to perform a self-consistent model calculation of the electronic and magnetic properties of diluted local-moment systems $A_{1-x}M_x$ described by ferromagnetic Kondo-lattice model ($s-f$ model), where we included disorder in the first environment shell by use of crystal field parameters between two non-magnetic, one magnetic and non-magnetic, and two magnetic atoms, respectively $\lambda^{AA},\lambda^{AM},\lambda^{MM}$, and to get the interconnected electronic and magnetic properties of systems like diluted ferromagnetic semiconductors (DMS) is proposed. We discuss in detail the dependencies of the key-terms such as the long range and oscillating effectice exchange integrals and the Curie temperature as well as the electronic and magnonic quasiparticle densities of states on the concentration $x$ of magnetic ions, the carrier concentration $n$, the exchange coupling $J$ and the crystal field parameters.

Annotation:

Background: KAM has received a lot of attention over the last decade, where organizations acknowledge the benefits, and choose to implement KAM programs within their companies. Research shows that the individual in a KAM manager role has a huge impact on the outcomes of KAM, crucially responsible for the relationships with the key accounts. Furthermore, there is a clear link between the selection of the right candidate in order to succeed with KAM, and the personality traits of a KAM manager. Problem: Limited research has been carried out on the personality traits of KAM managers connected to the FFM, yet scholars indicate that the individual has a large effect on the outcomes of KAM. Also, few researchers study both the buyer´s and the supplier's side within KAM relationships, even though mutual benefits are an essential part of KAM. Purpose: The purpose of the study is to identify if there is an existing mutual understanding between the buyer and supplier regarding valuable traits of a KAM manager to benefit KAM outcomes. Method: The study utilizes a qualitative research approach, collecting primary data through six semi-structured interviews. The number of participants was equally distributed between buyers and suppliers, all experienced working with KAM. A thematic analysis was then used to analyze the empirical findings. Conclusion: Based on the results, a conclusion is drawn that there is no mutual understanding between the buyer and supplier regarding valuable traits of a KAM manager. Aligning with previous research, all participants shared the view concerning the individual's importance in KAM, however having divided opinions about which personality traits would contribute to the valuable outcomes. The buyers emphasized the importance of structure and planning relating to the personality trait conscientiousness to optimize KAM outcomes, while the suppliers rather placed focus on aspects connecting to the personality trait extraversion.

Annotation:

Model and variable selection have attracted considerable attention in areas of application where datasets usually contain thousands of variables. Variable selection is a critical step to reduce the dimension of high dimensional data by eliminating irrelevant variables. The general objective of variable selection is not only to obtain a set of cost-effective predictors selected but also to improve prediction and prediction variance. We have made several contributions to this issue through a range of advanced topics: providing a graphical view of Bayesian Variable Selection (BVS), recovering sparsity in multivariate nonparametric models and proposing a testing procedure for evaluating nonlinear interaction effect in a semiparametric model. To address the first topic, we propose a new Bayesian variable selection approach via the graphical model and the Ising model, which we refer to the ``Bayesian Ising Graphical Model'' (BIGM). There are several advantages of our BIGM: it is easy to (1) employ the single-site updating and cluster updating algorithm, both of which are suitable for problems with small sample sizes and a larger number of variables, (2) extend this approach to nonparametric regression models, and (3) incorporate graphical prior information. In the second topic, we propose a Nonnegative Garrote on a Kernel machine (NGK) to recover sparsity of input variables in smoothing functions. We model the smoothing function by a least squares kernel machine and construct a nonnegative garrote on the kernel model as the function of the similarity matrix. An efficient coordinate descent/backfitting algorithm is developed. The third topic involves a specific genetic pathway dataset in which the pathways interact with the environmental variables. We propose a semiparametric method to model the pathway-environment interaction. We then employ a restricted likelihood ratio test and a score test to evaluate the main pathway effect and the pathway-environment interaction.

Mestrado em Contabilidade, Fiscalidade e Finanças Empresariais
A Air France-KLM (AF-KLM) é a companhia de bandeira da França, é resultado da fusão entre as empresas Air France (francesa) e KLM (holandesa) possuindo dois hubs principais situados em Paris e Schipol. O grupo é atualmente líder da europa em termos de tráfego e tem como objetivo ser uma das maiores companhias à escala global. O trabalho final de mestrado que se segue tem como objetivo principal estimar o valor intrínseco das ações da AF-KLM para 31 de dezembro de 2018. Este projeto é composto por uma revisão bibliográfica onde são analisados os métodos de avaliação possíveis e a partir da qual é definida a metodologia para este mesmo projeto. Foi também feita uma análise em relação ao ambiente macroeconómico, da indústria e especificamente da AF-KLM. De forma a calcular o valor intrínseco procedeu-se à avaliação por fluxos de caixa atualizados baseado em valores de FCFF pelo qual foi determinado um valor intrínseco de 11.33 euros para as ações da AF-KLM para a data de 31 de dezembro de 2018. Este valor sugere que as ações se encontram subvalorizadas e que possuem um potencial de crescimento de 19.55% face ao preço de 9.48 euros registado a 31 de dezembro de 2018. Através da avaliação relativa foram utilizados dois múltiplos, em que o enterprise valueto-EBITDA resultou num preço de 23.5 euros por ação e o price-to-earnings foi igual a 5.3 euros por ação culminando numa média de 14.43 euros por ação que corresponde a um potencial de crescimento de 52.2%.
Air France-KLM (AK-KLM) is the flag carrier of France resulted of the fusion between Air France (french) and KLM (dutch). It has two main hubs located in Paris and Schipol. The group is the current european leader in passenger traffic and aims to be one of the world's best airline companies. The following project aims to estimate the intrinsic value of AF-KLM's stock price as of December 31, 2018. It consists of a literature review where possible evaluation methods are analysed from which the methodology of this project is defined. An analysis was also made of the macroeconomic environment, industry and the company's specifics. In order to estimate the intrinsic value, cash flow discount model based on FCFF values was carried out whereby an intrinsic value of 11.33 euros was determined for AFKLM's shares as of 31 December 2018. This result suggests that shares are undervalued and have a growth potential of 19.55% compared to the closing price of 31 December 2018 (9.48 euros). Through the relative valuation two multiples were used, in which enterprise-value-to-EBITDA resulted in 23.5 euros per share and where the price-toearnings ratio gave a price of 5.3 euros per share, culminating in an average of 14.43 euros per share which corresponds to a growth potential of 52.2%.

How do the notions of programming and difference-making relate to one another? A higher-level property programs for an effect just in case, intuitively, the actual realizer of the property at any lower level gives rise to a realizer of the effect and any possible realizer at that level would also have done this. A higher-level property makes a difference to the effect just in case its presence programs for the effect and, in addition, its absence programs for the absence of the effect. Christian List and Peter Menzies argue for the capacity of the difference-making model to explain away the exclusion problem raised for physicalists by Jaegwon Kim. But the program model, developed in earlier work by Frank Jackson and Philip Pettit, offers a simpler and more straightforward way of handling the challenge.

Simple maps and dynamical systems are used to explore chaos in nature. The discussion starts with a review of the properties of nonlinear ordinary differential equations, including the useful concepts of phase portraits, fixed points, and limit cycles. These notions are developed further in an examination of iterative maps that reveal chaotic behavior. Next, the damped driven oscillator is used to illustrate the Lyapunov exponent that can be used to quantify chaos. The famous KAM theorem on the conditions under which chaotic behavior occurs in physical systems is also presented. The principle is illustrated with the Hénon-Heiles model of a star in a galactic environment and billiard models that describe the motion of balls in closed two-dimensional regions.

Basic concepts of inner shell double ionisation phenomena are discussed and examples are presented. An empirical model to calculate single-site K-shell double ionisation energies is proposed and the enhanced chemical shifts in double L-shell ionisation are illustrated. Core–valence double ionisation spectra are shown to closely resemble photoelectron spectra from single ionisation in many cases. Core–valence double ionisation spectra of NH3, CO, CO2, OCS, CS2, CF4, Si(CH3)4, benzene, and C60 are presented with analysis. In the context of core ionisation it is customary to use the very economical ‘KLM’ notation, which is universally used in Auger spectroscopy, as well as the chemists’ familiar 1s, 2s, 2p, and so on. This chapter uses the KLM notation sparingly where its brevity is an advantage, so a short table list of equivalents is also included here.

Half a century after Poincaré first glimpsed chaos in the three-body problem, the great Russian mathematician Andrey Kolmogorov presented a sketch of a theorem that could prove that orbits are stable. In the hands of Vladimir Arnold and Jürgen Moser, this became the Kolmo–Arnol–Mos (KAM) theory of Hamiltonian chaos. This chapter shows how KAM theory fed into topology in the hands of Stephen Smale and helped launch the new field of chaos theory. Edward Lorenz discovered chaos in numerical models of atmospheric weather and discovered the eponymous strange attractor. Mathematical aspects of chaos were further developed by Mitchell Feigenbaum studying bifurcations in the logistic map that describes population dynamics.

Annotation:

There is significant disagreement concerning the frequency response of tilting pad journal bearings (TPJBs) due to non-synchronous excitations. Two linear models for the frequency dependence of TPJBs have been proposed. The first model, the full-coefficient or KC model, considers Np tilting pads and rotor motions for Np + 2 degrees of freedom. Dynamic reduction of the KC model results in eight frequency-dependent stiffness and damping coefficients. The second model, based on results from bearing system identification experiments, yields twelve frequency-independent stiffness, damping, and mass (KCM) coefficients. Experimental data has been presented to support both models. There are major differences in the two approaches. The analysis in this paper takes a new approach of considering the pad dynamics explicitly in a state-space modal analysis. TPJB shaft and bearing pad stiffness and damping coefficients are calculated using a well known laminar, isothermal analysis and a pad assembly method. The TPJB rotor and pad full system eigenvalues and eigenvectors are then evaluated using state-space methods, with rotor and bearing pad inertias included explicitly in the model. The full bearing coefficient results are also non-synchronously reduced to the 8 stiffness and damping coefficients are and expressed as shaft complex impedances. The system identification method is then applied to these complex impedances, and the state space modal analysis is applied to the resulting KCM model. The damping ratios, natural frequencies, and mode shapes from the two bearing representations are compared. Two example TPJBs are examined in detail. The analysis indicated that four underdamped modes, two forward and two backward, dominate the rotor response over excitation frequencies from 0 to running speed. The full coefficient, non-synchronously reduced model predicts additional critically damped or overdamped modes due to the additional degrees of freedom as compared to the identified KCM model. The KCM model results in natural frequencies that are 63–65 percent higher than the full coefficient model. The difference in modal damping ratio estimates depend on the TPJB considered, with KCM being 7–17 percent higher than the full coefficient model. The full coefficient model also indicates that the bearing pads contribute significantly to the underdamped modes. The results indicate that the system identification method results in a reduced order model of TPBJ dynamic behavior. Additionally, the differences in the modal calculated system natural frequency and modal damping have potential implications for rotordynamic analyses of flexible rotors, such as critical speed and stability analyses.

Annotation:

Conventional numerical methods can capture the inherent variability of long-range outdoor sound propagation. However, computational memory and time requirements are high. In contrast, machine-learning models provide very fast predictions. This comes by learning from experimental observations or surrogate data. Yet, it is unknown what type of surrogate data is most suitable for machine-learning. This study used a Crank-Nicholson parabolic equation (CNPE) for generating the surrogate data. The CNPE input data were sampled by the Latin hypercube technique. Two separate datasets comprised 5000 samples of model input. The ﬁrst dataset consisted of transmission loss (TL) ﬁelds for single realizations of turbulence. The second dataset consisted of average TL ﬁelds for 64 realizations of turbulence. Three machine-learning algorithms were applied to each dataset, namely, ensemble decision trees, neural networks, and cluster-weighted models. Observational data come from a long-range (out to 8 km) sound propagation experiment. In comparison to the experimental observations, regression predictions have 5–7 dB in median absolute error. Surrogate data quality depends on an accurate characterization of refractive and scattering conditions. Predictions obtained through a single realization of turbulence agree better with the experimental observations.

A numerical, two-dimensional hydrodynamic model of the Mississippi River, from Thebes, IL, to Tiptonville, TN (128 miles/206 km), was developed using the Adaptive Hydraulics model. The study objective assessed current patterns and flow distributions and their possible impacts on navigation due to Birds Point New Madrid Floodway (BPNMF) operations and the Len Small (LS) levee break. The model was calibrated to stage, discharge, and velocity data for the 2011, 2015–2016, and 2017 floods. The calibrated model was used to run four scenarios, with the BPNMF and the LS breach alternately active/open and inactive/closed. Effects from the LS breach being open are increased river velocities upstream of the breach, decreased velocities from the breach to Thompson Landing, no effects on velocity below the confluence, and cross-current velocities greater than 3.28 ft/s (1.0 m/s) within 1186.8 ft (60 m) of the bankline revetment. Effects from BPNMF operation are increased river velocities above the confluence, decreased velocities from the BPNMF upper inflow crevasse (Upper Fuseplug) to New Madrid, cross-current velocities greater than 1.5 ft/s (0.5 m/s) only near the right bank where flow re-enters the river from the BPNMF lower inflow/outflow crevasse Number 2 (Lower Fuseplug) and St. Johns Bayou.

Annotation:

This study analyzes mobility patterns during the COVID-19 pandemic for eight large Latin American cities. Indicators of mobility by socioeconomic status (SES) are generated by combining georeferenced mobile phone information with granular census data. Before the pandemic, a strong positive association between SES and mobility is documented. With the arrival of the pandemic, in most cases, a negative association between mobility and SES emerges. This new pattern is explained by a notably stronger reduction in mobility by high-SES individuals. A comparison of mobility for SES decile 1 vs decile 10 shows that, on average, the reduction is 75% larger in the case of decile 10. According to estimated lasso models, an indicator of government restrictions provides a parsimonious description of these heterogeneous responses. These estimations point to noticeable similarities in the patterns observed across cities. We also explore how the median distance traveled changed for individuals that travel at least 1 km (the intensive margin). We find that the reduction in mobility in this indicator was larger for high-SES individuals compared to low-SES individuals in six out of eight cities analyzed. The evidence is consistent with asymmetries in the feasibility of working from home and in the ability to smooth consumption under temporary income shocks.

Annotation:

A low-cost multicamera Unmanned Aircraft System (UAS) is used to simultaneously estimate open-coast topography and bathymetry from a single longitudinal coastal flight. The UAS combines nadir and oblique imagery to create a wide field of view (FOV), which enables collection of mobile, long dwell timeseries of the littoral zone suitable for structure-from motion (SfM), and wave speed inversion algorithms. Resultant digital surface models (DSMs) compare well with terrestrial topographic lidar and bathymetric survey data at Duck, NC, USA, with root-mean-square error (RMSE)/bias of 0.26/–0.05 and 0.34/–0.05 m, respectively. Bathymetric data from another flight at Virginia Beach, VA, USA, demonstrates successful comparison (RMSE/bias of 0.17/0.06 m) in a secondary environment. UAS-derived engineering data products, total volume profiles and shoreline position, were congruent with those calculated from traditional topo-bathymetric surveys at Duck. Capturing both topography and bathymetry within a single flight, the presented multicamera system is more efficient than data acquisition with a single camera UAS; this advantage grows for longer stretches of coastline (10 km). Efficiency increases further with an on-board Global Navigation Satellite System–Inertial Navigation System (GNSS-INS) to eliminate ground control point (GCP) placement. The Appendix reprocesses the Virginia Beach flight with the GNSS–INS input and no GCPs.

O presente relatório contém resultados parciais do projeto “Definição de áreas prioritárias para recuperação florestal”, referentes a atividade “Uso e comparação da acurácia de diferentes modelos preditivos de desmatamento na Amazônia”. O objetivo deste estudo foi a implementação de modelos preditivos de desmatamento na Amazônia brasileira com base nas técnicas de Random Forest (RF), Spatial Random Forest (SpRF) e Integrated Nested Laplace Approximations (INLA) e comparação dos erros obtidos com cada modelo. Uma base de dados geográficos foi gerada por meio da integração de dados de diversas instituições brasileiras, como IBGE, MMA e INPE, utilizando células de 25 x 25 km e uma janela temporal de um ano. Os principais drivers de desmatamento identificados estão relacionados à fragmentação florestal e à expansão de áreas de pastagem na Amazônia, corroborando com outros trabalhos encontrados em literatura. A modelagem obteve melhores resultados com o uso dos modelos RF e SpRF em relação aos modelos do tipo INLA, com menores valores de erro médio quadrático obtido em conjuntos de dados de treinamento e validação dos algoritmos. A previsão de desmatamento para o ano de 2020 foi de 31 mil km2 , dados que apresentam uma superestimava devido ao método utilizado para o cálculo do desmatamento. Entre as ações identificadas que podem ser adotadas em trabalhos futuros para melhorar a previsão do desmatamento, cita-se o uso da abordagem CLUE e a melhoria de algumas bases de dados utilizada, a exemplo da malha viária.
