Ce mémoire de maîtrise décrit la première phase de la réalisation d'un prototype de polarimètre portable à 37GHz. Les polarimètres portables actuellement disponibles sur le marché coûtent au dessus de 200 000$ et sont plus adaptés à l'utilisation au laboratoire que sur le terrain. Ils nécessitent le transport de gaz à l'état liquide pour leur calibration et ont de grands besoins énergétiques. Tous ces facteurs contribuent à leur haut coût et à leur grande complexité d'utilisation. Cette première phase du projet vise à développer la partie analogique du récepteur micro-onde qui sera au coeur du prototype. D'autres travaux, à la suite de cette maîtrise, seront nécessaires afin de rendre le récepteur utilisable et compléter le prototype. Les spécifications du polarimètre ont d'abord été définies. Par la suite, la décision d'acheter ou de fabriquer chaque sous-système/circuit a été prise. Ensuite, les activités d'achat et de conception ont eu lieu. Il a été constaté que les techniques standards utilisées pour fabriquer des circuits microruban n'étaient pas assez précis. Un procédé de fabrication a alors été développé et les circuits ont été fabriqués. Le tout a finalement été intégré. La finalité de ce projet a été un système analogique qui permet d'amplifier et de traiter une onde incidente à haute fréquence et à faible intensité pour la rendre mesurable par un système d'échantillonnage et de traitement numérique. Ce système numérique sera conçu et fabriqué à une date ultérieure.

In the recent years, the concept of “port community” has been adopted by the maritime transport industry in order to achieve a higher degree of coordination and cooperation amongst organizations involved in the transfer of goods through the port area. The business processes of the port community supply chain form a complicated process which involves several process steps, multiple actors, and numerous information exchanges. One of the widely used applications of ICT in ports is the Port Community System (PCS) which is implemented in ports in order to reduce paperwork and to facilitate the information flow related to port operations and cargo clearance. However, existing PCSs are limited in functionalities that facilitate the management and coordination of material, financial, and information flows within the port community supply chain. This research programme addresses the use of agent technology to introduce business process management functionalities, which are vital for port communities, aiming to the enhancement of the performance of the port community supply chain. The investigation begins with an examination of the current state in view of the business perspective and the technical perspective. The business perspective focuses on understanding the nature of the port community, its main characteristics, and its problems. Accordingly, a number of requirements are identified as essential amendments to information systems in seaports. On the other hand, the technical perspective focuses on technologies that are convenient for solving problems in business process management within port communities. The research focuses on three technologies; the workflow technology, agent technology, and service orientation. An analysis of information systems across port communities enables an examination of the current PCSs with regard to their coordination and workflow management capabilities. The most important finding of this analysis is that the performance of the business processes, and in particular the performance of the port community supply chain, is not in the scope of the examined PCSs. Accordingly, the Agent-Based Middleware for Port Community Management (ABMPCM) is proposed as an approach for providing essential functionalities that would facilitate collaborative planning and business process management. As a core component of the ABMPCM, the Collaborative Planning Facility (CPF) is described in further details. A CPF prototype has been developed as an agent-based system for the domain of inland transport of containers to demonstrate its practical effectiveness. To evaluate the practical application of the CPF, a simulation environment is introduced in order to facilitate the evaluation process. The research started with the definition of a multi-agent simulation framework for port community supply chain. Then, a prototype has been implemented and employed for the evaluation of the CPF. The results of the simulation experiments demonstrate that our agent-based approach effectively enhances the performance of business process in the port community.

The continuous growth of international trade and development of containerization bring about the emergence and development of inland ports- inland sites performing seaport functions that do not require waterways (also called dry ports). However, so far inland/dry port research has paid very limited attention to Canadian inland ports. CentrePort Canada, located in Winnipeg where manufacturing is the largest industry, is the first Canadian inland port with three transportation modes and foreign trade zone status and is endeavoring to attract more businesses especially in manufacturing. This thesis thus aims to investigate whether CentrePort Canada, especially the North part, is an attractive site for manufacturers to locate their businesses. Attractiveness is measured by matching CentrePort Canada features with the location factors considered by specific manufacturers. Eight case studies involving in-depth interviews are conducted to explore manufacturers’ perspectives on site selection factors and CentrePort Canada (North). Three groups of manufacturers are included: established companies located in CentrePort Canada South, new companies located in CentrePort Canada North, and established firms located elsewhere in Winnipeg. This thesis concludes that CentrePort Canada North is so far attractive to Winnipeg-based companies having plans to relocate within the city and outside manufacturers distributing to new markets. Winnipeg-based companies more appreciate CentrePort Canada-related features including available land, low land cost, and CentrePort Canada Way, while outside manufacturers are more interested in regional features such as low business costs, taxes and incentives, market access, and ease of transportation. For attracting new manufacturing operations, governments need to provide more manufacturing-related incentives and the inland port should improve its services and promote more actively to the outside manufacturing industry. This study not only adds to Canadian inland port research, but also supports the adaptation of a relational approach integrating behavioral and structural location theories in addressing a site attractiveness evaluation. / May 2017

With increasing awareness of the potential impacts posed by climate change, many ports and their surrounding regions have undertaken adaptation planning and proactive actions so as to build a resilient and sustained business. However, most of them are still at the embryonic stage in understanding the problem and find it very challenging regarding adaptation planning and implementation. This thesis addresses the current issue in adaptation to climate change impacts at ports, regions and supply chains through quantitative and qualitative analyses. A global survey is designed to investigate port decision-makers’ perceptions and knowledge about climate change adaption. It explores the existing impacts posed by sea level rise (SLR), and high winds and storms, and demonstrates the potential impacts of adaptation measures. Analytical results suggest that, despite the forecast of more serious impacts posed by these climate change risks in the near future, port decision-makers still have strong doubts about the effectiveness of adaptation measures and planning. In-depth interviews in a case study on Port Metro Vancouver (Canada) are conducted to further investigate the barriers (especially institutional ones) that hinder the process of climate change adaptation, and thus calls attention for its regional efforts. Based on the literature review and analysis, this study argues that a paradigm shift in adaptation planning, notably from ‘go it alone’ to ‘collaborative’ approach involving all major port stakeholders, is urgently needed. The thesis also highlights the pivotal role of tailor-made adaptation methods in accordance with a specific climate change risk in the adaptation planning. Besides, two innovative, ‘paradigm shift’ recommendations are proposed to climate adaptation planning: (1) a method based on usage unit to allocate investment responsibility; and (2) the establishment of a neutral agency (e.g., a collaborative network) with the power to promote the adaptation process. In addition, a flexible combination of engagement in collaborative projects and individual efforts for ports is suggested so as to implement adaptation works. / October 2016

M.Com. (Economics) / The inability of the formal sector in South Africa to create a sufficient number of employment opportunities for the country's growing economically active population, causes an increase in the size of the informal sector. It is in the informal sector where the unemployed look for earning opportunities in an effort to ensure survival. Three main reasons given for this inability of the formal sector to create a sufficient number of employment opportunities include: high levels of growth in the annual number of new entrants to the labour market; a decrease in the economy's production elasticity of employment; and the high elasticity of substitution between capital and labour ...

Die Erfahrungen mit zentralvenösen Kathetersystemen der kinderchirurgischen Abteilung der Chirurgischen Universitätsklinik Würzburg in dem Zeitraum von 1995 bis 2004 sind in dieser Arbeit zusammengetragen worden. Die Untersuchung beschäftigt sich sowohl mit subjektiven Faktoren (Alter, Zugangsvene, Grunderkrankung) als auch mit dem Vergleich der beiden Kathetersysteme bezüglich aufgetretener Komplikationen. Eine Schwierigkeit dieser Arbeit lag darin, die gesammelten Daten mit anderen Publikationen zu vergleichen. Begriffsungenauigkeiten und -vielfalt erschwerten die Gegenüberstellung der Ergebnisse. Trotz der relativ einfachen Operationsverfahren können zentralvenöse Kathetersysteme problematisch sein. Die Wahl des Kathetersystems, die Grunderkrankung und das Alter des Kindes sowie die Anlagevarianten gehören zu den wesentlichen Einflussfaktoren und müssen berücksichtigt werden. Der Hickmankatheter schneidet im Vergleich zum Portkatheter auf Grund von Komplikationen schlechter ab und benötigt so eine strenge Indikationsstellung. Dennoch hat dieser seine festen Indikationen, da er durch sein doppeltes Lumen sowohl zur Chemotherapie als auch zur Stammzellinfusion genutzt werden muss. Das Portsystem zeichnete sich im Allgemeinen durch eine niedrige Komplikationsrate aus. Zu den maßgeblichen Komplikationen zählen die Dislokation und die Infektion, wobei die Dislokation meist bei den Frühkomplikationen auftritt und die Infektion vermehrt die Spätkomplikationen betrifft. Durch ein erfahrenes Operationsteam sowie eine kompetente Nachsorge durch die Kinderklinik der Universität Würzburg gelang es, die Komplikationsrate gering zu halten. Der Einsatz von vollständig implantierbaren Kathetern kann gerade Kindern durch die geringe Freiheitseinschränkung und Komplikationsrate eine große Erleichterung sein. / Experiences of two types of central venous access are compared for children in the age of 0-16 years. Sepsis and dislocations were the most important complications. The risk of catheter occlusion occurs less often. Using a totally implantable port-catheter-system a better comfort and a lower complication rate is achieved.

“Spirit of Improvement” explores the social, economic, and architectural consequences of waterfront improvement initiatives undertaken in Boston, New York, Philadelphia, and Charleston from the waning years of the colonial period through the passage of the first federally-sponsored warehousing act in 1846. City-dwellers replaced a haphazardly-constructed warren of crooked streets, wooden storehouses and buildings, and dilapidated wharves of the colonial period, with orderly streetscapes, brick and stone buildings, and expanded infrastructure dedicated to local and international commerce. Though in each city, construction differed in scale and regional form, improvements everywhere were a daunting physical, financial, and political task. This dissertation seeks to present the stories of men and women throughout American cities to uncover the social and economic complexities that lay at the heart of improvement initiatives in the colonial and early national periods. Merchants and speculators sought new forms of government authorization and the consent of property holders to reorder the landscape. Architects and engineers drafted cutting-edge designs for warehouses and harbors that looked to European examples and embraced the aesthetics of neoclassicism, industrial technology, and emerging theories of public health and disease prevention. White and black laborers dredged harbors, extended docks, and erected brick and stone warehouses. Female boardinghouse and shopkeepers established businesses adjacent to the wharves. Not only did residents confront the persistence of improvement projects in their midst, they also confronted their personal relationships to the abundance of interests jostling for prominence in the early-national marketplace. As a result, these initiatives proved highly contentious both for the elites who could afford to fund competing projects, as well as for the artisans, free and enslaved laborers, small business and property holders, and families living and working on the margins of society. As the cities’ poor and middling sorts witnessed the transformations occurring around them, many were left to grapple with the question, “Improvement, but for whom?” Today, inhabitants of America’s port cities will find many of these themes all-too familiar: the presence of corporate development along shorelines; the role of celebrated architects and planners in the design and construction of expensive waterfront buildings; the ousting of long-term residents and businesses in the face of high rents or shifting clientele; and the emergence of a socially invisible, but economically essential, service-sector workforce who provide the necessary labor to keep these ventures afloat. “Spirit of Improvement” seeks to uncover the complex historical roots of America’s fascination with waterfront development—a phenomenon that stretches back to the improvement initiatives of the early republic, when merchant-entrepreneurs began to truly exploit infrastructure’s economic potential. In the early nineteenth century, capitalist development served the interests of merchants and businessmen involved international trade and commerce. Today, we look to the future of our urban waterfronts and confront the historical foundations on which these physical and social structures stand.
