Yang, Xiaotian. "New transition state optimization and reaction path finding algorithm with reduced internal coordinates." Thesis, Sorbonne université, 2021. http://www.theses.fr/2021SORUS481.
Full textThe characteristics of a chemical reaction are largely determined by the molecular structures associated with the reactant, the product, the transition state, and the path connecting them. Therefore, locating the stationary points on the molecular potential surface is the first step towards successful numerical modeling. Mathematically, reactants, products, and reactive intermediates are local minima on the potential energy surface. Two local minima are connected by a stationary point which is a maximum along the reaction path but a minimum in all other directions. This saddle point is called the transition state (TS) between the two local minima. Once all the important stationary points on the potential surface have been located, one can model the whole reaction process, including the mechanism(s) of the reaction and its kinetic and thermodynamic properties (reaction rate, equilibrium constant, exothermicity, etc.. For multistep reactions, the existence of intermediate(s) complicates the reaction mechanism. In addition, there may be multiple possible reaction paths, wherein different intermediate structures connect the same reactants and products. In these complicated scenarios, having a full minimum-energy path showing how reactants and products are connected by various sequences of structures is especially useful, as it provides researchers with atomistic detail about the reaction mechanism. This can be useful, for example, for designing better catalysts. [...]

Full textOf the three Rhenish mystics, Suso is the only one that accompanied his texts with suggestive pictures, often the reflection of his mental images, of his visions. In the first part, after studying his life and works, we have attempted to give a summary of his illustrated writings ; even though one manuscript only was supervised by him, the artists after him worked on his advice. We have also tried to describe the civilization of images surrounding him and, above all, how, therefrom, he managed to pass his teachings, giving himself as an example and, with images, tracing the mystic way for the nuns he was in charge of. In the second part, we have shown "images driving out images": after scrutinizing a manuscript of the 14th century, we have conducted a work of comparison between the different Exemplars known. But these images driven out by other images in the end, lead to their disappearing, and in the third part, we have shown the process of rejection, as Suso saw it, through detachment - on Entbildung, leading to Uberbildung, i.e transformation into the Deity : the mystic union, a prelude to the beatific vision

Full textIn recent years, column generation methods have been the subject of many publications about solving a greater number of combinatorial optimisation pro-blems. They correspond to a particular use of the revised Simplex method on a decomposed and restricted problem. An auxiliary problem generates new va-riables not present initially. In this thesis, we focus our interest on the cases where the auxiliary problcm is a constrained shortest path problem in a graph. Various improvcments have been proposed in thc literature, but they arc all limitcd to a particular problem. This thesis proposes to facilitate thc reuse of those improvcments in different problems. For this, we propose a generic formalism to model such problems and a description of thc scarch for solutions using goals. We then present new and different practical improvements applicable te varions problems. More precisely, the contributions are : an efficient algorithm for elcmentary shortcst path in the subproblem, a combination of expert heuristics and Constraint Programming in the subproblem, search strategies for the subproblem, a Constraint Programming global constraint for shortest path subproblem, cutting planes applied to the path-based master problem, heuristics and search strategies for the master problem. Those improvements are validated on three different real applications : ve-hicle routing, crew scheduling, and network design. For each of those applications, we produce several experimental results sho-wing how some combinations of the proposed contributions help to improve the ultimate solutions. Finally, a column and cut generation framework has been implemented that eases the development of such applications and that includes most of our pro-posal

Full textThis thesis focuses on urban passenger multimodal transportation. In practice, a multimodal transportation problem requires taking into account several objectives and specific constraints related to modes or sequence of used modes. Such constraints are called viability constraints. This work has been carried out in collaboration with MobiGIS, a company specialized in consulting and development of applications around Geographical Information Systems.The problem studied in this thesis is the bi-objective multimodal viable point-to-point shortest path, aiming at minimizing the total travel time and the total number of mode changes. Given the considered objectives, this problem is polynomial.On the basis of a multi-layered graph model of the multimodal transportation networks, and of a finite state automaton model of the viability constraints, we propose various algorithms for solving this problem, based on the principle of label setting and extension.We also proposed a new dominance rule based on the states of the automaton to reduce the number of labels explored by our algorithms. Bidirectional and A* variants are also proposed.The algorithms are evaluated the transportation network of the city of Toulouse and experiments demonstrate the interest of the proposed dominance rules and bidirectional approach. A prototype software implementing different features of the shortest path algorithms has been developed. It notably enables calculations of point-to-point routes, accessibility and origin-destination matrices

Full textThe work presented in this thesis aims at proposing methods for computing bicycle paths across a metropolitan. Several criteria such as distance, safety and effort must be considered in the path computation. The difficulty is to compute paths under a time constraint of a few seconds, in order to integrate the computation in the respond-time of a web page.Two approaches were discussed to solve this problem. The first one is an a posteriori approach where all compromise solutions are computed and the second approach is an a priori method that takes user preferences into account to guide the search by the selection of the most promising sub-paths first. Finally, we propose to model the road network as a line graph to take into account new criteria,requiring costs on arc sequences for example. All this work was necessary to develop the service Géovélo, which is a multiobjective route planner adapted to bicycle. The service is available on a website and as mobile applications

Full textThe travel time representation has a major impact on user-oriented routing information. In particular, congestion detection is not perfect in current route planners. Moreover, the travel times cannot be considered as static because of events such as capacity drops, weather disturbances, or demand peaks. Former researches focused on dynamic travel times, i.e. that depend on departure times, in order to improve the representation details, for example concerning the periodicity of congestions. Real-time information is also a significant improvement for users aiming to prepare their travel or aiming to react to on-line events. However these kinds of model still have an important drawback : they do not take into account all the aspects of travel time variability. This dimension is of huge importance, in particular if the user risk aversion is considered. Additionally in a multimodal network, the eventual connections make the travel time uncertainty critical. In this way the current PhD thesis has been dedicated to the study of stochastic travel times, seen as distributed random variables.In a first step, we are interested in the travel time statistical modeling as well as in the travel time variability. In this goal, we propose to use the Halphen family, a probability law system previously developed in hydrology. The Halphen laws show the typical characteristics of travel time distributions, plus they are closed under addition under some parameter hypothesis. By using the distribution moment ratios, we design innovative reliability indexes, that we compare with classical metrics. This holistic approach appears to us as a promising way to produce travel time information, especially for infrastructure managers.Then we extend the analysis to transportation networks, by considering previous results. A set of probability laws is tested during the resolution of the stochastic shortest path problem. This research effort helps us to describe paths according to the different statistical models. We show that the model choice has an impact on the identified paths, and above all, that the stochastic framework is crucial. Furthermore we highlight the inefficiency of algorithms designed for the stochastic shortest path problem. They need long computation times and are consequently incompatible with industrial applications. An accelerated algorithm based on a deterministic state-of-the-art is provided to overcome this problem in the last part of this document. The obtained results let us think that route planners might include travel time stochastic models in a near future

Full textThe author presents the results of research carried out in the Vosges area of eastern France, within the framework of a research unit of the INRA research department on agrarian systems and development (Versailles). The study deals with the cantons of Neufchâteau, Coussey, Bulgneville and Chatenois. The objective is to detect the local determinants responsible for the diversity of agricultural situations analyzed at different spatial levels (from farm fields to groups of villages) during seven research operations (1975-1987), in particular the follow up of the states' general of agricultural development. The work promotes a localist point of view which is set here against "delocalizing" theories in agronomy, rural economy and sociology, in order to investigate the articulation between farm development and village development using the concept of "local technical referential", of technical profile and of village trajectory. The major results are methodological. Three converging approaches are privileged: the systematic consideration of the representations local actors have of their territory; the articulation of social networks with the territory; the sociotechnical analysis of farming activity, which requires that sociologists work closely with agronomists on common objects (e. G. The fields)
