Au purgatoire des utilités : les dépôts littéraires parisiens (an II - 1815) / In the purgatory of utilities : the parisian depots of books (1794-1815)

Robin, Cécile 30 March 2013 (has links)
Les dépôts littéraires regroupent des livres nationalisés de corps ou communautés supprimés et ceux confisqués à des émigrés ou condamnés. La thèse se compose de quatre parties: 1 ° Orchestrer les entrées de livres dans les dépôts littéraires: l'importance géostratégique de leur implantation illustre leur rôle d'intermédiaire entre anciens propriétaires et futurs possesseurs. L'organisation matérielle et la segmentation des espaces des dépôts sont conditionnées par la nature des travaux et la hiérarchisation des fonctions. 2° Acteurs et tutelles du projet: le personnel, chargé d'inventorier et de déplacer les livres, est majoritairement constitué d'hommes de lettres, reconvertis dans le nouveau service public de l'Instruction. L'intégration à la fonction publique leur assure un salaire minimum et témoigne de la reconnaissance de leurs compétences. La fonctionnarisation des personnels et l'institutionnalisation des dépôts littéraires reflètent l'importance politique du projet de redistribution des livres acquis à la Nation. 3° Une science en héritage, la bibliographie : les dépôts permettent la transition entre une opération de recensement et un instrument de péréquation. 4° Les destinations des livres des dépôts littéraires : la fonction des dépôts consiste à trier les livres qu'ils contiennent puis à leur donner la meilleure des destinations possibles, soit par la vente des ouvrages inutiles, soit par la mise à disposition des ouvrages utiles auprès d'établissements ou d'organes publics. La répartition s'opère suivant une politique de la demande, fondée sur un principe d'équité et déterminée par le domaine de spécialité et le rang institutionnel des destinataires. / The depots are established to put together the books nationalized or confiscated from religious communities after their suppression but also from émigrés and condemned persons. This thesis is composed of four parts: 1 ° Organize the intlux of books in the depots : they are put up in strategic places, to facilitate the movements of books between former owners and future possessors. The types of work and the different functions determine the material organisation and the segmentation of inner spaces. 2° Actors and supervision of the project: former men of letters are employed by the public service of state education to make the inventories and move the books. As employees of the State, the payment of salaries is guaranteed and their skills acknowledged. The institutionalization of the depots retlects the political importance of the project of redistribution of the books. 3° Bibliography, an inherited science : the depots allow the transition between an operation of inventory to an instrument of perequation. 4° The destinations of the books of the depots: the function of the depots is to determine the best purpose possible, either by selling the useless books or by putting the useful ones at the disposaI of public establishments or organs of govemment. The books are shared out according to the institutional position of the future possessors.

Bayesian network development for depots location selection with biomass supply system excellence

Abulhamail, Alaa Ashraf 09 August 2022 (has links) (PDF)
The renewable energy of the wood pellet market has taken great attention over the last few periods. However, the returns from the pellet business depend largely on how well the quality of biomass. The objective is to economically harvest pellets matching pellet standards set forward by the U.S. markets. The single-mindedness of this study is to develop a Bayesian network model to ensure a high-quality flow through the supply chain of the pallet industry in the top ten counties in Mississippi state. Multiple critical decisions (harvesting, storage, transportation, and quality control) of a biomass-to-pellet supply system could potentially affect the supply chain. The biomass-to pellet supply chain is an extremely challenging problem. For Multi-criteria Decision Making,we have developed criteria and sub-criteria associated with biomass-to pellet supply chain pellet. Experimental results specify that the biomass-to-pellet stream system is complex to the biomass quality parameters especially ash and moisture contents. Fifty were studied and ten locations were recommended and ranked based on affordability and resiliency of the availability of both corn stover and forest residues in the depot facilities. There are several anticipated and unpredicted energy turbulence in the Depots property. Pellets have been recognized as an alternative power approach to managing risk throughout power generation. These prospective users from using alternative power. This research proposes a solid foundation for in-depth future research to acquire detailed insights into how the Pellets depots location works in practice in Mississippi state to give a more substantial basis for strategic, tactical, and operational levels of possible risk profiles in Mississippi state.

The therapist scheduling problem for patients with fixed appointment times

Wang, Huan, master of science in engineering 27 February 2012 (has links)
This report presents a series of models that can be used to find weekly schedules for therapists who provide ongoing treatment to patients scattered around a geographical region. In all cases, the patients’ appointment times and visit days are known prior to the beginning of the planning horizon. Variations in the model include single vs. multiple home bases, homogeneous vs. heterogeneous therapists, lunch break requirements, and a nonlinear cost structure for mileage reimbursement and overtime. The single home base and homogeneous therapist cases proved to be easy to solve and so were not investigated. This left two cases of interest: the first includes only lunch breaks while the second adds overtime and mileage reimbursement. In all, 40 randomly generated data sets were solved that consisted of either 15 or 20 therapists and between roughly 300 and 540 visits over five days. For each instance, we were able to obtain the minimum cost of providing home healthcare services for both models using CPLEX 12.2. The results showed that CPU time increases more rapidly than total cost as the total number of visits grows. In general, data sets with therapists who have different starting and ending locations are more difficult to solve than those whose therapists have the same home base. / text

Large Scale Evacuation of Carless People During Short- and Long-Notice Emergency

Chan, Chi Pak January 2010 (has links)
During an emergency evacuation, most people will use their vehicles to evacuate. However, there is a group of people who do not have access to reliable transportation or for some reason cannot drive, even if they have their own automobiles - the carless. There are different groups of carless (disabled, medically homebound, poor or immigrant populations, etc.) who require different forms of transportation assistance during an emergency evacuation. In this study we focus on those carless who are physically intact and able to walk to a set of designated locations for transportation during an emergency, and we propose using public transit and school buses to evacuate this carless group. A model has been developed to accommodate the use of public transit and school buses to efficiently and effectively evacuate the carless. The model has two parts. Part 1 is a location problem which aims at congregating the carless at some specific locations called evacuation sites inside the affected area. To achieve this goal, the affected area is partitioned into zones and this congregating of the carless has been formulated as a Single Source Capacitated Facility Location Problem. Changes in the demand of the carless in zones over different periods of a day and over different days of the week have been considered and included in the model. A walking time constraint is explicitly considered in the model. A heuristic developed by Klincewicz and Luss (1986) has been used to solve this location model.Part 2 is a routing problem which aims at obtaining itineraries of buses to pick up the carless at evacuation sites and transport them to safe locations outside the affected area, such that the total number of carless evacuated with the given time limit is maximized. A Tabu search heuristic has been developed for solving the routing problem. Computational results show that the Tabu search heuristic efficiently and effectively solves the routing problem; in particular, the initial heuristic produces a high quality initial solution in very short time. This study has also made slight contribution to the development of the Tabu search technique.

Stochastic feasibility assessments of orbital propellant depot and commercial launch enabled space exploration architectures

Chai, Patrick R. 07 January 2016 (has links)
The 2010 National Space Policy of the United State of America introduced by President Obama directed NASA to set far reaching exploration milestones that included a crewed mission to a Near Earth Asteroid by 2025 and a crewed mission to Martian orbit by the mid-2030s. The policy was directly influenced by the recommendations of the 2009 Review of United States Human Space Flight Plans Committee, which called for an evolutionary approach to human space exploration and emphasized the criticality of budgetary, programmatic, and program sustainability. One potential method of improving the sustainability of exploration architectures is the utilization of orbital propellant depots with commercial launch services. In any exploration architecture, upwards of seventy percent of the mass required in orbit is propellant. A propellant depot based architecture allows propellant to be delivered in small increments using existing commercial launch vehicles, but will require three to five times the number of launches as compared to the using the NASA planned 70 to 130 metric ton heavy lift launch system. Past studies have shown that the utilization of propellant depots in exploration architectures have the potential of providing the sustainability that the Review of United States Human Space Flight Plans Committee emphasized. However, there is a lack of comprehensive analysis to determine the feasibility of propellant depots within the framework of human space exploration. The objective of this research is to measure the feasibility of a propellant depot and commercial launch based exploration architecture by stochastic assessment of technical, reliability, and economic risks. A propellant depot thermal model was developed to analyze the effectiveness of various thermal management systems, determine their optimal configuration, quantify the uncertainties in the system models, and stochastically compute the performance feasibility of the propellant depot system. Probabilistic cost analysis captured the uncertainty in the development cost of propellant depots and the fluctuation of commercial launch prices, and, along with the cost of launch failures, provided a metric for determining economic feasibility. Probabilistic reliability assessments using the launch schedule, launch reliability, and architecture requirements of each phase of the mission established launch success feasibility. Finally, an integrated stochastic optimization was performed to determine the feasibility of the exploration architecture. The final product of this research is an evaluation of propellant depots and commercial launch services as a practical method to achieving economic sustainability for human space exploration. A method for architecture feasibility assessment is demonstrated using stochastic system metrics and applied in the evaluation of technical, economic, and reliability feasibility of orbital propellant depots and commercial launch based exploration architectures. The results of the analysis showed the propellant depots based architectures to be technically feasible using current commercial launch vehicles, economically feasible for having a program budget less than $4 billion per year, and have launch reliability approaching the best single launch vehicle, Delta IV, with the use of redundant vehicles. These results serve to provide recommendations on the use of propellant depots in exploration architectures to the Moon, Near Earth Objects, Mars, and beyond.The 2010 National Space Policy of the United State of America introduced by President Obama directed NASA to set far reaching exploration milestones that included a crewed mission to a Near Earth Asteroid by 2025 and a crewed mission to Martian orbit by the mid-2030s.

Evaluation of the efficiency and effectiveness of the regional procurement service depots in the Philippines : a case of region 1 : a thesis presented in partial fulfilment of the requirements for the degree of Master in Public Policy at Massey University, Albany, New Zealand

Vicente, Ria S. January 2008 (has links)
The focus of this research is to examine the efficiency and effectiveness of recent procurement reform done by the Government of the Philippines, particularly the centralized procurement system for common-use supplies, materials, and equipment. The centralized procurement system is adopted with the intent of taking advantage of the savings inherent to bulk purchasing, streamlining procurement procedures, and reducing opportunities for corruption in the procurement of the abovementioned items. By legislative authority under Republic Act No. 9184, the centralized procurement system was made mandatory among all government agencies, government owned and controlled corporations and local government units in the purchase of their supplies, materials and equipment requirements. With the introduction of tighter budget and the stronger pressure for good governance, the contributions of procurement policy and institutions of procurements to the achievement of good governance and potential relation to development has been gaining global recognition. Given the association of procurement to the way public money is spent, the issue on corruption is also central to this research. There has been a growing recognition of the relationship between corruption and development – the more corrupt a country is, the more underdeveloped it becomes. With the daunting task of battling against corruption, the country’s strategy is to direct its efforts in combating corruption in specific areas, like public procurement. This thesis demonstrates that the centralized procurement system offers a significant reduction in processing times in the conduct of procurement. Additionally, it offers opportunities for savings generation with the cheaper prices of goods and the reduction of administrative cost associated with procurement. More over, it provides a procurement framework where opportunities for administrative corruption are reduced. This leads to the conclusion that the centralized procurement system is efficient in that it reduces administrative processing time and concomitant costs. This, in the long run, will benefit the procuring entities and ultimately the tax payers. However, the emphasis placed on achieving administrative savings is at the expense of other measures of effectiveness such as quality of goods being supplied and the quality of services being extended to client agencies. Moreover, the lack of effective inventory and control system may pave the way to greater waste. Without an effective inventory and control system as well as an improved quality control system, the centralized procurement system that works faster and cheaper may not be better after all.

Estimating Carbon Pool and Carbon Release due to Tropical Deforestation Using High-resolution Satellite Data / Carbon Release due to Tropical Deforestation

Rahman, Md. Mahmudur 14 December 2004 (has links) (PDF)
Forest-cover in the tropics is changing rapidly due to indiscriminate removal of timber from many localities. The main focus of the study is to develop an operational tool for monitoring biomass and carbon pool of tropical forest ecosystems. The method was applied to a test site of Bangladesh. The research used Landsat ETM+, Landsat TM and IRS pan images of 2001, 1992 and 1999 respectively. Geometrically corrected Landsat ETM+ imagery was obtained from USGS and adjusted to the field using GPS. Historical images were corrected using image-to-image registration. Atmospheric correction was done by modified dark object subtraction method. Stratified sampling design based on the remote sensing image was applied for assessing the above-ground biomass and carbon content of the study area. Field sampling was done during 2002-2003. Dbh and height of all the trees inside the sample plots were measured. Field measurement was finally converted to carbon content using allometric relations. Three different methods: stratification, regression and k-nearest neighbors were tested for combining remote sensing image information and field-based terrestrial carbon pool. Additional field sampling was conducted during 2003-2004 for testing the accuracy. Finally regression method was selected. The amount of carbon released and sequestrated from the ecosystem was estimated. The application of the developed method would be quite useful for understating the terrestrial carbon dynamics and global climate change.

No. of bitstreams: 1 3145.pdf: 4807955 bytes, checksum: e7ba1c165199af2b5606877c0fadf24b (MD5) Previous issue date: 2010-03-12 / Universidade Federal de Sao Carlos / The aim of the present study was to investigate the effects of resistance training on skeletal muscle lipid content, liver lipid content, heart lipid content, fat depots and lipid profile in ovariectomized rats. Wistar adult female rats were grouped into: sedentary (Sed-intact); ovariectomized sedentary (Sed-Ovx); strength trained (ChronicEx-intact) and ovariectomized strength trained (ChronicEx-Ovx) (n= 10 per group). A 12-week strength training period that consisted in climbing a 1.1-m vertical ladder with weights attached to rats tail was used. The sessions were performed once every 3 days with 4-9 climbs and 8-12 dynamic movements per climb. Ovariectomy increased liver lipid content, fat depots, heart and muscle lipid content. There was an increase in atherogenic index and negative change in lipid profile due to ovariectomy. Resistance training decreased lipid content in liver, soleus, tibialis anterior, fat depots (mesenteric and retroperitoneal) and lipid profile, independently of ovarian hormone status. These results indicate the potential benefits of resistance training as an alternative strategy to control the effects of ovariectomy on fat depot, lipid profile, and tissue lipid content. / O objetivo do estudo foi investigar os efeitos do treinamento de força sobre o conteúdo lipídico no músculo esquelético, fígado, coração, depósitos de gorduras e perfil lipídico em ratas ovariectomizadas. Ratas fêmeas adultas foram divididas em quarto grupos: Sedentário (Sed-Intacto); Sedentário ovariectomizado (Sed-Ovx); Treinado intacto (CrônicoEx-Intacto); Treinado ovariectomizado (CrônicoEx-Ovx) (n = 10 por grupo). Foi realizado um período de 12 semanas de treinamento de força que consistia em subidas de uma escada vertical de 1,1 metros, com peso atado no rabo. As sessões foram realizadas uma vez a cada três dias com 4- 9 subidas e 8-12 movimentos por subida. Foram analisados os conteúdos de lipídios no músculo esquelético, fígado, coração, depósitos de gorduras (urogenital, mesentérico e retroperitoneal) e perfil lipídico. Ovariectomia aumentou o conteúdo lipídico no fígado, músculos esqueléticos, coração e depósitos de gordura. Foi observado um aumento no índice aterogênico e mudanças negativas no perfil lipídico devido à ovariectomia. O treinamento de força diminuiu o conteúdo de lipídio hepático, nos músculos esqueléticos sóleo, tibial anterior, depósitos de gordura (mesentérico e retroperitoneal) e perfil lipídico independente do estado hormonal ovariano. Esses resultados indicam os benefícios potenciais do treinamento de força com uma estratégia alternativa para controlar os efeitos da ovariectomia sobre os depósitos de gordura, perfil lipídico e conteúdo tecidual de lipídio.
