Striving towards a circular economy has led to the re-investigation of many existing processes, with the target of developing more sustainable variants. In our present economy, plastics form an important and omnipresent material affecting our daily lives. They are inexpensive, durable, corrosion resistant, and light weight leading to their use in a wide variety of applications.Within the plastic chemical recycling scheme, Fischer-Tropsch synthesis (FTS) could play a key role as the syngas feedstock that is converted in it, can be generated via the gasification of the considered plastics. This syngas is then chemo-catalytically converted into hydrocarbons such as paraffins and light olefins. Typical FTS catalysts are based on supported cobalt or iron species.Among the mechanistic kinetic models, the comprehensive variant based on the Single Event MicroKinetics (SEMK) concept has been widely applied in the field of oligomerization, autoxidative curing, etc. and has proven to be a versatile tool to simulate Fischer-Tropsch synthesis. However, developing mechanistic models for every chemical engineering challenge is not always feasible due to their complexity and the in-depth knowledge required to build such models.A detailed evaluation on the potential of using machine learning approaches to match the performance of results obtained using the Single-Event MicroKinetic model was carried out. Initially, the focus was on a single dominant output scenario (methane selective catalyst). The current work thus shows that more widely applied techniques in data science can now be applied for systematic analysis and interpretation of kinetic data. Similar analysis using experimental data can also help experimenters in their preliminary analysis, to detect hidden trends in the data, and thus to identify importance features. After gaining confidence on the investigated interpretation techniques, for the FTS reaction with single dominant output, a similar investigation on the potential of iron based catalysts with enhanced light olefin selectivity is carried out next

Resumo: Resultados de campanhas de medição realizadas visando o desenvolvimento de uma fer-ramenta para o projeto, implantação e análise de sistemas de RFID são mostrados nesse traba-lho. Particularmente, a perda de percurso de rádio a partir de um leitor de RFID até um TAG, e de volta para o leitor é caracterizada na banda 915 MHz, para diferentes distâncias de separação leitor-TAG, alturas de TAG e de antena do leitor. Vários cenários de propagação foram considerados, incluindo ambientes exteriores e in-teriores, para os quais foi colhido um extenso número medidas. Os dados de campo são, então, comparados a uma versão melhorada do modelo clássico perda caminho 2-ray, ajustada para incluir também os padrões de radiação da antena não omnidirecionais no leitor. Além disso, foi investigado, por meio da análise de medidas de campo, o efeito da mobi-lidade do TAG no sinal recebido no leitor. Para a coleta das medidas, foi construído um aparato composto de uma esteira de velocidade controlada, onde foram instalados TAGs de teste. Os resultados de medida mostraram que a mobilidade do TAG provoca uma diminuição do valor médio e um aumento da variância do sinal recebido no leitor. Essa atenuação extra e a variância do sinal não são fortemente afetadas pelo valor da velocidade. Por fim, esses efeitos de propagação são incorporados em um modelo matemático, que pode ser utilizado para a simulação e planejamento de sistemas RFID
Abstract: Results of measurement campaigns carried out aiming at the development of a tool for design, deployment, and analysis of RFID systems are shown. Particularly, the radio path loss from an RFID reader towards the test TAG and back to the reader is characterized at the 915 MHz band. The path loss is estimated based on the received signal strength measured at the reader, for different reader¿TAG separation distances and different antenna TAG heights. Several propagation scenarios have been considered, including outdoor and indoor environments for which an extensive number of typical real manufacturing plants have been chosen. The field data are then compared to a proposed novel, improved version of the classical 2-ray path loss model, adjusted to include non-omnidirectional antenna radiation patterns at the reader. In addition, the effect of TAG mobility in the received signal at the reader was also investigated, by means of field measurements. To collect the field measurements, an apparatus was designed and constructed, consisting of a mat of controlled speed, on which test TAGs were installed. The results showed that TAG mobility decreases the average value increases the variance of the received signal at the reader. This extra attenuation and the increased variance of the signal are not strongly affected by the value of speed. Finally, these two effects are incorporated into a mathematical model that can be used for simulation and planning of RFID systems

ABSTRACTPOULIOT, GEORGE. A Variable Resolution Nonhydrostatic Global Atmospheric Semi-implicit Semi-Lagrangian Model. (Under the direction of Dr. Fredrick H.M. Semazzi.)The objective of this project is to develop a variable-resolution finite difference adiabatic global nonhydrostatic semi-implicit semi-Lagrangian (SISL) model based on the fully compressible nonhydrostatic atmospheric equations. To achieve this goal, a three-dimensional variable resolution dynamical core was developed and tested.The main characteristics of the dynamical core can be summarized as follows: Spherical coordinates were used in a global domain. A hydrostatic/nonhydrostatic switch was incorporated into the dynamical equations to use the fully compressible atmospheric equations. A generalized horizontal variable resolution grid was developed and incorporated into the model. For a variable resolution grid, in contrast to a uniform resolution grid, the order of accuracy of finite difference approximations is formally lost but remains close to the order of accuracy associated with the uniform resolution grid provided the grid stretching is not too significant. The SISL numerical scheme was implemented for the fully compressible set of equations. In addition, the generalized minimum residual (GMRES) method with restart and preconditioner was used to solve the three-dimensional elliptic equation derived from the discretized system of equations. The three-dimensional momentum equation was integrated in vector-form to incorporate the metric terms in the calculations of the trajectories. Using global re-analysis data for a specific test case, the model was compared to similar SISL models previously developed. Reasonable agreement between the model and the other independently developed models was obtained. The Held-Suarez test for dynamical cores was used for a long integration and the model was successfully integrated for up to 1200 days. Idealized topography was used to test the variable resolution component of the model. Nonhydrostatic effects were simulated at grid spacings of 400 meters with idealized topography and uniform flow. Using a high-resolution topographic data set and the variable resolution grid, sets of experiments with increasing resolution were performed over specific regions of interest. Using realistic initial conditions derived from re-analysis fields, nonhydrostatic effects were significant for grid spacings on the order of 0.1 degrees with orographic forcing. If the model code was adapted for use in a message passing interface (MPI) on a parallel supercomputer today, it was estimated that a global grid spacing of 0.1 degrees would be achievable for a global model. In this case, nonhydrostatic effects would be significant for most areas.A variable resolution grid in a global model provides a unified and flexible approach to many climate and numerical weather prediction problems. The ability to configure the model from very fine to very coarse resolutions allows for the simulation of atmospheric phenomena at different scales using the same code. We have developed a dynamical core illustrating the feasibility of using a variable resolution in a global model.

This work calculates analytically and numerically the spectral density for the two impurity uncorrelated Anderson model (U = O). Our results serve as an initial step towards understanding models with electronic correlation. The studied model describes the interaction between conduction-band electrons of a metal and localized magnetic impurities. The simplification U = O turns the Hamiltonian quadratic, allowing us to split it into two parts: one involving only even operators (even channel), the other involving odd operators (odd channel). Each term has a form differing a little from that for the Resonant Level Hamiltonian. Our results include analytic diagonalization as well as numerical calculations using the method of the Renormalization Group, adapted for the two impurity case. The traditional tridiagonalization method imposes particle-hole symmetry, while our treatment preserves the energy dependence of the coupling, between the impurities and the conduction-band, and consequently, the natural asymmetry of the model. The simplicity of the Hamiltonian allowed us to (1) identify characteristics of the model that affect adversely the acuracy of the numeric calculation and (2) find a way to surround such difficulties. The results here found helped the development of the calculation of the spectral density of the correlated model, developed simultaneously in our research group.

In this work, we study the Falicov-Kimball model with two localized spinless impurities hybridized with conduction electrons of a host metal, therefore, valence fluctuation is intrinsic to the model. The conduction states are also electrostatically scattered whenever a charge is present em the local levels of the impurities. The study was realized computing thermodynamics properties of the model, more specifically, we analyze the temperature dependent specific heat end charge susceptibility for many different parameters of the model. The Numerical Renormalization Group with two discretization parameters is used to obtain the spectrum of the model, from what the thermodynamics is obtained. We discuss the importance of going beyond the usual approximation that projects all moment at the Fermi Level. We begun our study of the thermodynamical properties analyzing values of the parameters space, where the model becomes quadratic (that is, where hybridization or Coulomb scattering are absent), and thus simple interpretations of the data are possible. We verified, for example, that for non-zero hybridization, the system shows Fermi liquid behavior at low temperature. The Wilson ratio, defined here with the charge susceptibility instead of magnetic one, has the universal value R = 1, whenever the hybridization is present. For some choices of the model parameters the model behaviors like heavy fermion.
