1. Goel, Ankit. Gradient-, Ensemble-, and Adjoint-Free Data-Driven Parameter Estimation.

Degree: PhD, Aerospace Engineering, 2019, University of Michigan

In many applications, models of physical systems have known structure but unknown parameters. By viewing the unknown parameters as constant states, nonlinear estimation methods such as the extended Kalman filter, unscented Kalman filter, and ensemble Kalman filter can be used to estimate the states of the augmented system, thereby providing estimates of the parameters along with the dynamic states. These methods tend to be computationally expensive due to the need for Jacobians, ensembles, or adjoints, especially when the models are high-dimensional. This dissertation presents retrospective cost parameter estimation (RCPE), which does not require gradients, ensembles, or adjoints. Rather, RCPE estimates unknown parameters from a single trajectory, and requires updating an adaptive integrator gain for each unknown parameter. RCPE is applicable to parameter estimation in linear and nonlinear models, where the parameterization may be either affine or nonaffine. The main contribution of this work is to show that the parameter estimates may be permuted in an arbitrary way, and thus a permutation is needed to correctly associate each parameter estimate with the corresponding unknown parameter. RCPE is illustrated through several numerical examples including the Burgers equation and the Global Ionosphere Thermosphere Model (GITM), where the goal is to estimate representational parameters such as eddy diffusion coefficient and thermal conductivity coefficients using measurements of atmospheric variables such as total electron content, density, temperatures etc. The next part of the dissertation focuses on forgetting in the context of recursive least squares (RLS) algorithm. It is a well-known fact that classical RLS with forgetting diverges in the cases where the excitation is not persistent. In this work, an information-driven directional forgetting technique is proposed, which constrains the forgetting to directions in which new information is available, thereby allowing RLS to operate without divergence during periods of loss of persistency. In the last part of this dissertation, retrospective cost adaptive control (RCAC) is extended to the problem of control allocation in overactuated systems. In particular, it is shown that the applied control input lies in the range of the target model used in RCAC, thereby providing a simple technique to constrain the control input to a desired subspace. Finally, RCAC is extended to asymptotically enforce output constraint by formulating the problem as a problem of following conflicting commands, and is used to prevent a scramjet combustor from unstarting using pressure measurements.

2. Zamorano-Ford, Jorge. Essays on environmental regulation under imperfect competition : Essais sur la régulation environnementale dans un cadre de concurrence imparfaite.

Degree: Docteur es, Économie, 2018, Paris 1

Cette thèse couvre deux sujets : le dessin des permis à polluer et la gestion des déchets. Le premier chapitre analyse la mise en œuvre des permis à polluer. Le chapitre se concentre sur les impacts de la distribution liés à la sévérité de l’allocation gratuite basée sur la production courante quand deux secteurs sont couverts par le marché des permis et le plafond reste constant. Un nouveau type d’augmentation des profits dans les secteurs qui ne sont pas exposés à la concurrence internationale a été démontré théoriquement. Le deuxième chapitre traite la question de la différenciation de l’allocation des permis dans les différentes régions, liée à la possibilité des entreprises à délocaliser. Les conditions dans lesquelles le bien-être décroît avec la délocalisation sont déterminées. Dans ce cas, des distributions gratuites de permis peuvent être utilisées pour éviter la délocalisation des entreprises. Le troisième chapitre compare l’efficacité des programmes de la responsabilité élargie du producteur (REP) avec l’efficacité d’une ex-ante taxe. La taxe permet plus de flexibilité ex-ante quant aux conditions du marché, mais la REP permet plus d’adaptation ex-post aux réalisations des coûts. Ainsi, l’efficacité relative de la REP augmente avec l’incertitude des coûts et la compétitivité du marché.

This thesis covers two subjects. One is the design of pollution permits and the other is the waste management. The first chapter analyses the implementation of pollution permits. It focuses on the distributional impacts linked with the stringency of output-based allocation,when two sectors are covered by the market for permits and the total cap is held constant. Theoretically demonstrated is a new type of profit increase in sectors that are not exposed to international competition. The second chapter addresses the issue of differentiating permit allocation across areas, this being linked to the possibility of firms to relocate. The conditions under which welfare decreases with relocation are determined. In such a case, free allowances may be used to prevent firms from relocating. The third chapter compares the efficiency of extended producer responsibility (EPR) programs and the efficiency of an ex-ante tax. The tax allows more ex-ante flexibility regarding market conditions, but the EPR allows more ex-post adaption to cost realizations. As a result, the relative efficiency of the EPR increases with uncertainty of the costs and competitiveness of the market.

3. Arif, Faisal. Three Essays on the Economics of Climate Change .

Degree: 2012, University of Ottawa

Thesis Abstract: Chapter I: Regional burden sharing of GHG mitigation policies – A Canadian perspective. The distribution of the burden of cost arising from the reduction of greenhouse gas (GHG) emissions is a contentious issue in policy discussions; more so among regional jurisdictions in the federalist countries with decentralized authorities over environmental regulations. In this setting, often the policy discussions are focused on the distribution of regional emission reduction targets that, in turn, entails negotiations over the distribution of the scarcity rents and the regional transfers of wealth. The allocation of regional emission entitlements is thus a key factor that could hinder the political feasibility of a national GHG mitigation policy. In this paper, we build a multi-region computable general equilibrium (CGE) model of the Canadian economy to assess the implications of different burden sharing rules governing the national GHG abatement policy with a cap-and-trade system of emission permits. In addition to assessing the impacts of traditional regional emissions allocation rules that involve intra-regional transfers of wealth, we consider a particular emission allocation that avoids such transfers, which may be a more palatable option given the context of likely fierce negotiations over the issue. Our results indicate to differing outcomes depending on the allocation policy in use. The CGE framework is also able to shed light on the transmission mechanisms that drive the results underlying the policy options. Chapter II: Endogenous technological change and emission allowances. Given the imminent threat of global warming due to GHG emissions, a number of emission mitigation policies have been proposed in the literature. However, they generally suffer from the classical equity-efficiency trade-off. High costs from equity concerns often render environmental policies politically unattractive and thus hard to implement. Recent advancement in the climate policy modeling literature that incorporates endogenous technological change (ETC) into the framework can potentially bring new insights into this debate. Using an inter-temporal, multi-sector CGE approach with ETC incorporated into the framework, this paper builds a model that focuses on the equity-efficiency debate for the policymakers. Canada is chosen as the country of investigation for this purpose. The paper provides a new welfare ranking of four permit allocation policies that address the equity-efficiency trade-off. In a second-best setting with pre-existing distortions, output-based allocation (OBA) of emission permits is compared to three other policy options: (i) an emissions trading system with grandfathered allocation (GFA), (ii) an auction permit trading system where permit revenue is recycled to lower payroll taxes (RPT), and (iii) a hybrid of OBA and R&D subsidy (O-R&D). We find that adapting OBA, as well as O-R&D, is welfare improving over GFA. The implicit output subsidy, entailed in the OBA policy, mitigates against the…
