Full textThe safe and reliable energy conversion based on real-time emergency forecasting of the dynamics of pulse energy conversion systems (PECS) is studied in this thesis under realistic variations of environmental parameters, of PECS input energy and also of parameters of PECS themselves. The study is realized following three interrelated successive stages: present state stationarity analysis of the system, short-term emergency forecasting one-to-one and long-term forecasting. Accordingly, the particular purpose of this thesis is to increase the efficiency of real-time processes of emergency forecasting in PECS dynamics, based on decision-making one-to-one in the present system state by the both output signal time series and a-priori data on dynamics, with use of the bifurcation approach and PECS dynamics fractal regularities. The fundamental idea used for this purpose achievement consists in that, the present state of the system is mapped in real-time into 2-D specific spaces in which the motion existence domains are preliminarily formed, then the dynamics evolution is forecasted regarding the bifurcation boundaries of these domains. And the possibility of both, formation of motion existence domains without overlapping between them and structurization of stable system states within each of the domains, is stipulated by PECS dynamics fractal regularities. The particular algorithm of real-time emergency forecasting based on the abovementioned idea is worked out, with the results of numerical simulations in agreement with the experimental studies

Full textBus is cheaper than other transport modes. However, maintaining optimal operations is harder than for streetcars or subways since buses are surrounded by traffic flows. Sometimes, buses of the same route bunch and travel together instead of keeping constant time headways. This phenomenon increases the average waiting time of passengers. As a result, they may tend to shift to other transport modes. This thesis proposes some methods to keep bus routes regular. Two main lines of research are investigated.First, classical models of bus routes do not account for external events like traffic signals and traffic flows. Due to this gap, existing control strategies only apply on buses through their drivers.Traffic flows are not controlled to favor buses compared to cars. Thus, the first area of research consists in refining bus models to account for external events. Several travel time estimation methods on urban arterials are proposed. They are based on the kinematic wave model (LWR). It is known to be a fine trade-off between simplicity and robustness to properly reproduce traffic dynamics.Second, control strategies are often applied once the bus route is too disrupted to be restored to regularity. Predictions of future bus route states could improve the efficiency of regulations. The second area of research consists in using the refined bus models in real time operations. The model forecasts the evolution of buses on their route for short-term. The predictions are evaluated thanks to real data to guarantee their quality. Then it enables regulations to be applied before bunching. In particular, height holding control methods are presented and compared in simulation

Full textThis thesis aims to reconcile real-time identification of business cycle phases with asset management. The business cycle is characterized by phases of expansion and recession, with varying durations and amplitudes. Macroeconomic data used to identify these phases are marked by publication delays and asynchronicity in their availability. Markov-switching dynamic factor models are a typical econometric framework to manage these characteristics. In the wake of the extreme event of Covid-19 (in terms of the shock's magnitude and its relatively short duration), many models previously employed to identify and date regime changes in the economic cycle have become inadequate for capturing smaller-scale reversals.The first chapter of this thesis develops an extension of the aforementioned methodological framework by introducing dynamic volatility into the unobserved business cycle dynamics. This solution reduces the impact of extreme shocks in the regime identification process while retaining them to establish a more robust detection of future cyclical reversals. The delay and asynchronicity of macroeconomic data availability are crucial issues for policymakers and market participants.The second chapter of this manuscript introduces and demonstrates the utility of considering market price data to establish a more concurrent measure of cyclical downturns. A particular class of assets, the "Asset Swap spreads" (a risk premium fixed between two counterparts exchanging future corporate bond coupons for a risk-free rate), when aggregated, produce coincident evaluations of macroeconomic recessions. These prices help mitigate the opportunity cost induced by the absence or delay of official macroeconomic information. When applied in the context of hedging strategies, these signals prove to be highly useful for investors. Asset allocation must take into account economic downturns, but this factor alone is not sufficient in the portfolio construction process.The third chapter deploys a portfolio allocation based on the identification of macroeconomic regimes, adding signals related to market sentiment and monetary policy stance. Compared to a classic 60% equities/40% bonds portfolio, the performance based on the three-signal approach allows investors to optimize the risk-adjusted return during both stressed and expansion periods

Full textThe présent research is concerned with real-time flood forecasting based on conceptual rainfall-runoff modeling. The model used is GR3J model developed with daily time step. The first part of the study has focussed on validation of the model using hourly data and analysis of the model parameters : response surface, sensibility and variabiity. Founded upon the precedent step, a new methodology for adjusting model parameters has been worked out in the second part of the study. It is characterized by : 1) operational framework in which the adjustment is carried out over a short period in connection with the continuous operation of the model, 2) objective function involving the last two forecast errors and parameters deviations and 3) joint adjustment of model parameters with model state. The methodology has been tested on two french experimental basins

Full textThis thesis is composed of three essays on real-time forecasting dynamic factor models. The main objective is to provide frameworks for high-frequency business cycle analysis in the presence of data revisions. This is relevant for three reasons. First, business cycle forecasting is a central question in macroeconometrics. Secondly, policy-makers would benefit from having access to timely, high-frequency information about business conditions to inform their decisions. Finally, decisions must frequently be made based on data that are subject to revision, and this data uncertainty should be incorporated into the decision-making process. After a review of the empirical business cycle literature and of models of business cycle turning points, we propose a rigorous framework for estimating monthly real US Gross Domestic Product (GDP). A recurring problem in this class of models is that estimates for monthly GDP are generally not consistent with quarterly estimates in the same way that quarterly estimates are not consistent with annual data. Our approach solves this problem. In the first essay (chapter 2), we develop and estimate a dynamic factor model treating the monthly Gross Domestic Product (GDP) as an unobservable latent variable. In contrast with existing approaches, the quarterly averages of our monthly estimates are exactly equal to the Bureau of Economic Analysis quarterly estimates. By construction, our monthly estimates have the advantage of being both timely and easy to interpret. The second essay (chapter 3) extends this framework by adding a Markov-switching model of business cycle regimes to the dynamic factor model. The model is now one with three levels, two of which have latent dependent variables. We pay particular attention to the sensibility of the usual indicators at turning points. The industrial production index, manufacturing and trade sales transmit more information about business cycle shocks to the common component (monthly GDP) than does employment. Finally, we integrate data revisions into our Markov- switching dynamic factor model in order to evaluate the effects of the revisions process on monthly estimates. It appears that data revisions have a significant impact on the co-movement of variables and on turning points without compromising the asymmetric nature of the business cycle. Keywords : Dynamic Factor Model (DFM), High-frequency, Real-time, Markov-switching, unobservable components, Revisions, co-movement, Turning points, Asymmetric, Business cycle.
