Full textIn the face of climate change, characterized by longer and more intense heatwaves, as well as irregular availability of water resources, it is essential to provide energy-efficient solutions to strengthen the resilience of buildings. Underground rainwater tanks are increasingly being exploited as systems for managing and storing water. By immersing a heat exchanger in the tank, it is possible to harness the geothermal effect of the water and surrounding soil to passively cool buildings. This research aims to study the performance and feasibility of these hybrid systems. A numerical model was developed and validated using data collected from the monitoring of full-scale prototypes over a period of nearly three years. The model was used to highlight the key factors influencing the system. The model was used to identify the factors influencing the system. Presizing rules were then established to assess the amount of energy that could potentially be recovered. The system model was then integrated into a building energy simulation tool to assess the gains in terms of occupant comfort

Full textThe current digital world is facing a number of issues, some of them linked to the amount of data that is being stored. The current technologies available as an offer to store data are not enough to store the totality of the storage demand. For this reason, new data storage technologies have to be developed. DNA molecules are one of the candidates available for novel data storage methods. The long lifespan of these molecules make it a good fit for the archival of data that is rarely accessed but needs to be stored for long periods of time. This data, often called “cold”, represents approximately 80% of the data in our digital universe. But DNA uses 4 symbols (A,C,G and T) to encode data against the usual binary code (0,1). For this reason, storing data into DNA requires a specific encoding system capable of translating a binary data stream into a quaternary data stream. In this thesis we will focus on new encoding methods from the Deep Learning state of the art, and we will adapt those methods for the encoding, decoding, compression and decompression of images on synthetic DNA

Full textThe distinctiveness and uniqueness of this research lies in the fact that it studies the long-term effects of credit rating on the value of banks rather than its immediate impact on the shares’ market price. The context of this research is the subprime crisis period of 2007-2008 during which banking stocks declined dramatically. This crisis caused a reawakening of interest in the study of credit rating and its impact on rated companies, especially when the rated companies are banks. The central question is to know how and to what extent credit rating helps to explain the long-term valuation of banks. How does the bank rating affect their performance, their governance, their capital structure, and therefore their value? Reciprocally, how does banks valuation impact their credit ratings? Our research follows the path of previous studies showing the impact of credit rating on the value of companies, but our approach is different. On one hand we focus only on the banking sector which is particular, and where the impact of credit rating can be different and stronger than on the other companies or industrial groups. On other hand we mobilize corporate governance approach that highlights the link between governance and valuation (Charreaux G., 1997; Gompers et al., 2003, Rob Bauer et al., 2003; Barth, Caprio and Levine, 2004; Levine, 2004). We also mobilize the neo-institutional theory developed by Meyer and Rowan (1977), Scott and Meyer (1983), DiMaggio and Powell (1991, 1997) and North (1990) that highlights the impact of institutions on organizations, their management and performance. These two approaches allow us to describe and analyze the ways and means by which credit rating can impact banks values in the long term, particularly by inspiring banks to use the “best practices” disseminated in the rating methodologies for banks. We try to empirically validate this analysis through a quantitative and econometric approach, using data from international databases such as Bloomberg, Bankscope and Fininfo about 161 large banks from 18 countries over the period 2001 to 2010. After building uniform credit rating indicators, we use bivariate analysis, regressions on panel data, Granger causality tests and multinomial logit model to test our assumptions. Our results show that one notch downgrade of a bank financial strength rating seems to cause a significant decrease of its valuation. This impact is not significant in a crisis period. The effect of the issuer credit rating on bank valuation is not significant. However, Granger causality tests show a feedback loop between the issuer credit rating, the weighted average cost of debt and the size of banks. The results of a logit multinomial model show that the bank financial strength ratings assigned by the rating agencies are influenced by the bank valuation indicators only for the years 2008 and 2009

Full textOptic Pathway Gliomas (OPG) are benign tumors that typically develop during early childhood. The management of patients varied throughout the last decades and was characterized by an emphasis on avoiding the use of radiotherapy. The role of chemotherapy in the management of OPG has increased. MRI is one of the fundamental elements of the management of these children. However, the tumor measurements are subject to inter and/or intraobserver variations. In an attempt to better understand the long-term outcomes of children treated with initial chemotherapy, long-term outcomes of OPG treated in France with up-front BB-SFOP chemotherapy were evaluated. A standardized and reproducible imaging classification for MRI that can be used as a reliable monitoring tool for patients with OPG was created and validated. The long-term outcomes of these patients showed a poorer prognosis for overall survival. Some clinical and radiological factors were associated with long-term vision loss. These findings could justify a risk-based approach to this tumor

Full textThe objective of this thesis is to analyze the oceanic variability in temperature and salinity over the period 1993-2008. For that purpose, it is necessary to use the maximum of observations available, namely in situ data of temperature and salinity, but also satellite data of sea surface temperature and sea height. To reach our objective, several steps are necessary: create a solid and coherent database, compare datasets to have a better physical understanding of the contents of every type of data then develop methods of combination to assemble the datasets. The cross-comparison of the altimetric and Argo datasets allows at first to verify the quality of the Argo dataset. In 2006, Guinehut and al published a paper on the comparison of SLA (Sea Level Anomaly) and DHA (Dynamic Height Anomaly). Today, the Argo dataset allows improving the comparisons. We explain why and we detail the differences between both studies. We also study the impact of the removal of the seasonal cycle and the influence of the vertical structure of the ocean in the barotrope / barocline distribution of the oceanic circulation. We end on the analysis of the SLA-DHA signal in term of seasonal and inter-annual circulation at 1000 meters deep. Armor3d Field, combination of satellite fields and in situ profiles exist for several years. The recent dataset supplied by Argo profilers allows improving considerably the parameters of the combination, to cover a better geographical zone and to have deeper fields. We show that both types of measures are needed, even to study the large scale variability of the ocean. Finally, we use our Armor3d fields to study the oceanic variability of the last 16 years

Full textBetween acquiring new knowledge and reviewing old knowledge to mitigate forgetting, learners may find it difficult to organize their learning time effectively. Adaptive spacing algorithms, like SuperMemo, can help learners deal with this trade-off. Such algorithms sequentially plan reviews of a given piece of knowledge to adapt to the specific and ongoing needs of each learner. Compared to a fixed and identical temporal spacing between reviews, several experiments have shown that adaptive spacing improves long-term memory retention of the piece of knowledge.To date, research on adaptive spacing algorithms has focused on the pure memorization of simple pieces of knowledge, which are often represented by flashcards. However, several studies in cognitive psychology have shown that the benefits of spacing out learning episodes on long-term retention also extend to more complex knowledge, such as learning concepts and procedures in mathematics. In this thesis, we have therefore sought to develop adaptive and personalized spacing algorithms for optimizing long-term mastery of knowledge components (KCs).First, we develop and present a new statistical model of learning and forgetting of knowledge components, coined DAS3H, and we empirically show that DAS3H has better predictive performance than several learner models in educational data mining. Second, we develop several adaptive spacing heuristics for long-term mastery of KCs and compare their performance on simulated data. Two of these heuristics use the DAS3H model to select which KC should be reviewed by a given learner at a given time. In addition, we propose a new greedy procedure to select the most promising subset of KCs instead of the best KC to review. Finally, in the last chapter of this thesis, we develop AC4S, a deep reinforcement learning algorithm for adaptive spacing for KCs. We compare this data-driven approach to the heuristic methods that we presented previously

Full textData explosion is one of the greatest challenges of digital evolution, causing the storage demand to grow at such a rate that it cannot compete with the actual capabilities of devices. The digital universe is forecast to grow to over 175 zettabytes by 2025 while 80% is infrequently accessed (“cold” data), yet safely archived in off-line tape drives due to security and regulatory compliance reasons. At the same time, conventional storage devices have a limited lifespan of 10 to 20 years and therefore should be frequently replaced to ensure data reliability, a process which is expensive both in terms of money and energy. Recent studies have shown that due to its biological properties, DNA is a very promising candidate for the long-term archiving of “cold” digital data for centuries or even longer under the condition that the information is encoded in a quaternary stream made up of the symbols A, T, C and G, to represent the 4 components of the DNA molecule, while also respecting some important encoding constraints. Pioneering works have proposed different algorithms for DNA coding leaving room for further improvement. In this thesis we present some novel image coding techniques for the efficient storage of digital images into DNA. We implemented a novel fixed length algorithm for the construction of a robust quaternary code that respects the biological constraints and proposed two different mapping functions to allow flexibility according to the encoding needs. Furthermore, one of the main challenges of DNA data storage being the expensive cost of DNA synthesis, we make a very first attempt to introduce controlled compression in the proposed encoding workflow. The, proposed codec is competitive compared to the state of the art. Furthermore, our end-to-end coding/decoding solution has been experimented in a wet lab experiment to prove feasibility of the theoretical study in practice
