Leurig, Sharlene. "Mapping the void : brownfield inventories by local governments." Thesis, Massachusetts Institute of Technology, 2007. http://hdl.handle.net/1721.1/39945.
Full textIncludes bibliographical references (p. 91-93).
Brownfields are abandoned or underused land whose redevelopment is complicated by the presence or perception of contamination. Nationally the United States Environmental Protection Agency estimates the number of brownfields to be more than half a million. As of 2002, the EPA requires states and tribal governments to inventory brownfields within their boundaries in order to receive federal funding for brownfield response programs; municipalities and regional planning offices eligible for competitive EPA brownfield grants are encouraged to first conduct a brownfield inventory. Assessment grants funding inventories are open-ended, allowing local governments to define their own methods of identifying brownfields and prioritizing parcels for redevelopment; as such there is little documentation of the way inventories are conducted. Through interviews with brownfield redevelopment professionals and inventory makers in Alabama, California, Kentucky, Massachusetts and New Jersey this thesis explores the ways local governments prioritize property types for identification, how they locate brownfields, how they incorporate community knowledge, and how inventories influence subsequent public funding allocations.
(cont.) This research indicates that inventories tend to focus on large sites close to infrastructure with the intention of marketing individual properties rather than strategically incorporating brownfield redevelopment into broader urban or regional planning. While local governments frequently design inventories in partnership with and for use by non-government actors, they tend to work almost exclusively with other professional groups and have marginal success at soliciting community participation. Though inventories are meant to capture brownfields that have eluded regulatory databases of contaminant release reports, fear of litigation from injured property owners and reliance on official property records bias inventory results to represent only the most visible brownfields. I conclude that the EPA should work with planning professionals to educate inventory makers on ways of creating strategic inventories. I also assert that brownfield inventories must include community partnerships in order to align brownfield redevelopment with community objectives and explore the legal and political implications of such partnerships.

Full textWhat can the local societies do to adapt themselves in a competitive and unsettled environment, mainly marked by the globalization and the strong development of the information and communication technologies ? How should they act and react to the contemporary changes ? We chose to use the local development to study these questions. Our approach based on the concept of immaterial resources allow us to work with the social interactions at a local level. The study has been carried out in two phases. First the observation of four development projects proved the interest of the immaterial resources. Then an experimentation-based research helped getting a better understanding of the processes at work during the action. The results obtained constitute the basis of the territorial intelligence and propose a new conception of the local action frameworks. In the end this research makes a few suggestions to improve the local development methodology. From a methodological point of view, the work done shows the interest of the experimentation to improve the tools and methods of the researcher

Full textThe boom in laparoscopic surgery means that new anesthetic strategies must be found, especially with respect to post-operative analgesia. Topical administration of local anesthetics is part of multimodal analgesia and many studies seeking to establish its interest in laparoscopic surgery provide contradictory results. Our aim is to contribute to an optimum way of administrating local anesthetics topically, with a view to: 1)homogeneous spreading on the peritoneum, 2)simultaneous humidification of insufflation gas, in order to prevent hypothermia. Hypothermia is due to evaporation of the peritoneum’s surface by contact with dry insufflation gas. Humidification could prevent this thermal energy loss. We performed several in vitro and in vivo (animal-) studies. Firstly, we evaluated the efficiency of hot versus cold humidification in hypothermia prevention. Secondly, we evaluated several humidification devices in order to assess their efficiency in delivering ropivacaine in the insufflation gas flow. Finally, we performed a pharmacokinetic study of intraperitoneal ropivacaine nebulization, by comparison with standard instillation. Our results open new prospects for intraperitoneal topical administration of local anesthetics: in the animal setting, we showed that hot humidification of insufflated gas did not provide any benefit in hypothermia prevention, in comparison with cold humidification, we established the potential value of a nebulizer, able to humidify and deliver local anesthetics along with CO2 insufflation during laparoscopy, we performed the first pharmacokinetic study of intraperitoneal ropivacaine nebulization, validating the safety of the technique. These results enable us to follow our research with a clinical trial to evaluate the effects of nebulized ropivacaïne and humidified insufflation gas in laparoscopic surgery

Full textThis thesis uses the Panoramic Survey Telescope and Rapid Response System 1 Survey to find new Local Group satellites such as dwarf galaxies and globular clusters. This survey is instrumental in helping resolve tensions that have become apparent between observation and theories. In a first phase, a search algorithm is developed, discovering five new satellites. Though yielding five discoveries, this number is lower than one would expect, assuming isotropy of the dwarf galaxies. This leads to the second aim of this thesis, namely quantifying the detection limits of the PS1 Survey. The detection efficiency maps over the entire PS1 sky can be used as a stepping–stone towards the quantification of the (an)isotropy of the Milky Way satellites’ distribution. Using this information, the luminosity function of these satellites can be re–derived

Full textInvestment in low carbon infrastructure is considered an important component of the fight against climate change. The mechanisms of climate regulation (such as carbon offsets) transfer to project developers the risks associated with reducing emissions of greenhouse gas (GHG) emissions, i. E. Operational and technological risk, or risks associated with the environmental monitoring and the regulatory mechanism itself. The success of projects depends importantly on the risk sharing arrangements between the private and public partners. It is shown that the delegation of tasks between the partners can create risks that affect the environmental effectiveness and economic efficiency of the project. For a sample of landfill gas flaring projects financed under the Clean Development Mechanism, it is shown that the outsourcing of the provision of technology creates additional risks. The outsourcing of the development of the official project documentation required by the UNFCCC and the separation of the operation of the landfill and the CDM project development appear to be manageable by risk sharing arrangements

Full textThrough the example of one of the first intercultural mediation departments, this thesis refers to the public commitment of "ethnicized" women, having partly managed to be recognized as legitimate interlocutors of political area in their so-called "sensitive" quarter. Being doubly or trebly minorities (as women, as immigrants, as living in a so-called "sensitive" quarter), their mobilization are subjected to specific constraints and opportunities, linked to political and social contexts, local as well as national. This thesis studies the shapes and the construction processus of their commitment, but also the interactions, cooperations, allowing experimentation of practices making a political use of "personal" experiences. More than a technical procedure connecting migrants and public institutions, this mediation is a political act aiming at the broadening and reinforcement of the freedoms of expression and action of ethnicized women in their quarters and families. Finally, the analysis of their biographical path demonstrates that they've got something out of this public commitment since they find equilibrium between their desire for social advancement and their social assignations as ethnicized women

Full textThe severe crisis in which the Venezuelan society has been immersed since the middle of the 1980’s is translated after ten years by profound development of the institutional image and its relations of the internal forces. For some decision makers or analysts, Venezuela would be a case of a transition towards a socialist model, etatist in terms of economics, semi authoritarianism and unique in terms of politics. For others, Venezuela embodies a new route for the participative democracy. Arriving to power, he started to change not only the state electoral mechanisms, but also the total logic of the political spectrum, setting new forms of local self-organisations to guarantee the hegemony of his government. Most of them poor people, who have historically been excluded from the politic arena, have been incorporated as individuals. One of main of Venezuelan objectives of the interior politics is the effective participation of citizens in the management of their issues. The popularity of Hugo Chavez is essentially based on the endorsement of the most disadvantaged part of the society, who seems to be the beneficiary of reforms undertaken, and of a large range of social programs financed by the oil grace. If the question of the participation is a current issue for many democrats, the shapes that take in Venezuela are new and unusual. Venezuela, country of numerous resources and potentialities, declares its socialist and revolutionary identity and gets involve firmly in the “road of the participation”. This policy is marked by a strong tension between a declared wish to put in place the terms of an effective participation and temptation to hold a centralised control of the process of decision. Will the social reforms take root on a permanent basis? What kind of democracy will be in question? Do the Venezuelan regimen constitute an alternative to deformations and insufficiencies of the democracy representative, created in its time like a kind of proceed allowing to filter the sovereignty popular?

In this document, we will discuss the nucleation and growth mechanisms associated with this low cost technique. In particular, we will see how the seed layer morphology can drive the one of the nanowires.

Nos últimos anos, temos observado um crescimento de uso e evolução das redes padrão IEEE 802.11. Atualmente, a Universidade de Brasília conta com uma infraestrutura de WLAN (do Inglês, Wireless Local Area Network) para atender os usuários de seus campi. Por meio dessa infraestrutura, a Universidade vem buscando alterativas para melhor atender a seus usuários, preferencialmente sem custos adicionais. Uma das alternativas é a implantação do serviço de voz sobre a rede sem fio da Instituição, em que os usuários utilizarão seus dispositivos móveis na comunicação, dispondo da facilidade de mobilidade. Ao se utilizar serviços de voz sobre redes sem fio, é necessário que parâmetros como atraso, variação de atraso e perda de pacotes estejam de acordo com recomendações para uma boa qualidade nas chamadas telefônicas. Além disso, prover mobilidade em redes padrão IEEE 802.11 envolve a transição do usuário móvel entre pontos de acesso, sendo um dos fatores de degradação da qualidade auditiva da voz. A solução de rede sem fio da UnB dispõe de tecnologias, como ClientMatch e os padrões IEEE 802.11k e 802.11r, que auxiliam o usuário móvel no processo de transição. Nesse contexto, o trabalho em questão buscou avaliar o impacto da tecnologia ClientMatch e dos padrões IEEE 802.11k e 802.11r no suporte à mobilidade e tráfego de voz, aferindo a qualidade auditiva da voz e o desempenho dos principais parâmetros de QoS (do Inglês, Quality of Service) em uma rede VoIP (do Inglês, Voice over IP). Mediante os experimentos realizados foi possível verificar que a tecnologia ClientMatch – Sticky Client não está voltada para suporte a mobilidade, apresentando baixo índice de atuação. As tecnologias IEEE 802.11k e 802.11r não produziram os resultados esperados nas avaliações realizadas. Mesmo com baixos índices de atuação da tecnologia ClientMatch – Sticky Client e resultados inesperados das soluções 802.11k e 802.11r, a rede WLAN da UnB permite um bom desempenho para o tráfego de voz mediante mobilidade, com níveis aceitáveis de qualidade da voz, devendo-se atentar para o processo de transição entre pontos de acesso, ClientMatch – Band Steering e o distanciamento entre os pontos de acesso. Além dos experimentos que buscaram avaliar o impacto da tecnologia ClientMatch e dos padrões IEEE 802.11k e 802.11r no suporte à mobilidade e tráfego de voz, foram realizados testes com CODECs (do Inglês, Coder–Decoder) mediante mobilidade do cliente móvel. O codificador–decodificador G711 foi o que apresentou melhores resultados nos experimentos executados com relação a qualidade auditiva da voz.
In recent years, we have observed an increase of use and evolution of the IEEE 802.11 based-networks. Currently, the University of Brasília (UnB) owns and operate a WLAN (Wireless Local Area Network) infrastructure to serve users of its campuses. Through this infrastructure, UnB is seeking alternatives to better serve its users, preferably without increasing its costs. An alternative is the implementation of voice over the wireless network of the Institution, where users utilize their mobile devices for communication while providing mobility. When using voice over wireless networks, parameters such as delay, delay variation and packet loss must comply with the recommendations for reasonable phone calls quality. Furthermore, providing mobility in IEEE 802.11 networks involves the transition of the mobile user between access points and this very process is one of the key factors of voice quality degradation. The UNB wireless networking solution encompasses technologies such as ClientMatch, IEEE 802.11r and 802.11k standards that assist the mobile user in the transition process. In this context, this work evaluates the impact of the ClientMatch technology, IEEE 802.11r and 802.11k standards in supporting mobility and voice traffic, while evaluating the audio quality, performance of the main QoS (Quality of Service) parameters in a VoIP network (Voice over IP). The conducted experiments showed that the ClientMatch – Sticky Client technology is not tailored for mobility support, presenting low rate of action, while the IEEE 802.11r and 802.11k technologies have not produced the expected results. Even with the low rates of operation of ClientMatch – Sticky Client technology and unexpected results of the solutions 802.11k and 802.11r, the UnB WLAN infrastructure provided good performance for voice traffic, even under moderate mobility, attaining acceptable levels of voice quality; nevertheless, the process of transition between access points, ClientMatch – Band Steering and the distance between access points may impact in the results. In addition to the experiments that seek to evaluate the impact of technology ClientMatch and IEEE 802.11r and 802.11k standards in supporting mobility and voice traffic, tests were performed with CODECs (Coder - Decoder) by mobility of mobile client. The encoder – decoder G711 showed the best results in the experiments performed with respect to the voice quality.

Full textThis doctoral thesis aims to provide a theorization of Local Economic Development (LED) in the Least Developed Countries (LDC). It also presents a synthesis of the conditions and assumptions of programs and institutions to reach transformative and sustainable change in local territories. Such a change is intended to drive the LDCs towards a sound development trajectory. The topic of the thesis is placed within the framework of the strategic options of local development and the choice of societies in the Least Developed Countries.The research, based on a case study of local development financing, is carried out with four qualitative data sources collected from 2014 to 2017 in the field of a less advanced economy. The epistemological posture starts by the nature of the problems identified and the specificities of the Least Developed Countries. The pragmatic constructivist approach made it possible to answer and explain observable phenomena related to the problem of identifying processes leading to local economic development following appropriate funding mechanism.The results of this doctoral research have highlighted an empirical framework for local development in LDCs.The contributions of this doctoral thesis numerous. First, they are of a theoretical nature, through an understanding of the local governance system in the least developed countries. The theoretical framework specific to the LDCs is thus analysed and allows to develop a set of preconditions for local development in the LDCs. Secondly, the contributions of this work deal with development policies and public policies.Indeed, we propose financing strategies adapted to the specificities of LDCs based on the two pillars of local development in the least developed economies: local governance and entrepreneurs, on the so-called "mixed" financing mechanisms. The theoretical model and LED preconditions provide an overview of strategies to implement the virtuous circle of LED in these economies

Once observed the development of the use of pictures after the change of the printing technqiue, this work emphasizes the importance of the part played by photo in the way t0 make up into pages to organize the news into a hierarchy. Examining the evolution of the content of newspapers (both throughout time for a particular edition and at the same times for each of three editions), it tires to stress the similarities and the peculiarities of dailies, believing that the personality of newspapers expresses itself rather into the local pages, while they tend to an increasing homogenization of the choice of subjects illustrations at national and international level. Stressed at last thanks to semiotic and semiologic studies, this work tries to uncover the values expressed by thez regional daily press with the passing of the years through the study of a shared subject : the national holiday of the 24 ,july from 1950 to 1988

Full textIn vivo electroporation (EP) is used as a strategy to improve the immune response induced by DNA vaccines. However, its local effect on the innate immune cells has not been fully described. We developed in vivo fluorescence imaging approaches to highlight the cell behavior in the site of vaccination in macaques. Our results show that the local EP not only increases the amount and the distribution of the vaccine antigen, but also induces the mobilization and migration of Langerhans cells. Furthermore, EP causes the recruitment of leukocytes into the skin and subcutaneous tissue and promotes the production of pro-inflammatory cytokines. These early events that result from the use of the EP as a delivery system for DNA vaccines, highlight its potential as a vaccine adjuvant

Full textTo improve the efficiency of the public sector, a decentralization process has been engaged in a large number of developing countries. This thesis, in four parts, analyzes various aspects of decentralization in developing countries. Part 1, which consists in a review of literature, studies the expected theoretical effects of decentralization, examines their relevance in the particular context of developing countries and, draws up a critical assessment of empirical studies evaluating the existence of such effects (chapter 1). Part 2 focuses on the relevance of an essential argument in favor of decentralization, largely ignored in studies on developing countries: the "competition principle". More precisely, we analyze the existence of strategic interactions between local governments in a context of weak fiscal resources (case of Benin, chapter 2) and in the absence of local democracy (case of China, chapter 3). Part 3 relates to the vertical relationship between the central government and local governments. In particular, we focus on the effect of central fiscal transfers on the level of local own-Revenue in Benin (chapter 4) and on the determinants of the allocation of fiscal transfers between local governments in Senegal (chapter 5). Finally, in part 4, we determine the average and distributional impacts of decentralization on the access to basic services by local population (chapter 6)

Full textThe aim of this work was to synthesize small size (~1-3 nm) metal oxide nanocrystals namely titanium dioxide (TiO2), tin dioxide (SnO2) and zinc oxide (ZnO), and to study their structure. Syntheses were conducted via non-aqueous or even strictly non-hydrolytic sol-gel methods under kinetic control. The structural characterization was mainly carried out by X-Ray diffraction methods, transmission electronic microscopy and the study of pair distribution functions, obtained by X Ray total scattering, coupled with atomic scale modelling methods. In the case of TiO2, anatase nanocrystals were obtained with sizes ranging between 4 nm and 8 nm. The molar ratio of the oxygen donor with respect to titanium was shown to be an important parameter to control the nanoparticle size. In peculiar conditions we have been able to isolate an intermediate phase characterized by very small sized and poorly crystallized nanoparticles which the structure can be assimilated to a disordered brookite structure. Concerning SnO2, rutile-type nanocrystals were synthesized with sizes ranging between 2 nm and 4 nm. The use of an ether as oxygen donor led to the simultaneous formation of an organic polymeric phase and of primary nanoparticles characterized by an intermediate structure close but still different from the rutile-type structure. Moreover, the use of benzyl-type solvents in the presence of tin tetrachloride led to the formation of water in the system. Lastly, for ZnO, we have shown that using an organic base to induce the formation of the metal oxide network in a methanolic solution of zinc acetate in the presence of a strong complexing agent of the zinc allowed us to obtain wurtzite nanocrystals of ultrasmall sizes around 1 nm. Even for the smallest sizes, the nanoparticles exhibit a structure very close to that of wurtzite with an increasing disorder of the cationic network

Full textThis dissertation examines the quality of the transmission of VoIP (Voice over IP) in wireless LAN (Local Area Network Wireless). To achieve this objective tests were performed on the bench using voice codecs G729, G711, G723 and GSM analyzing characteristics of delay and loss of packets. The paper presents results that indicate the effect of the phenomena of instability of wireless networks in the performance of VoIP. These variations show significant changes in the quality of voice depending on the used environment and the distance between the transmitter and receiver.

Full textIn spite of party supported candidacies, rarely autonomous ones, in the elections, the French elite from the Maghreb does not reach success within the framework of the uninominal system. We find no mayors of average or big cities, no presidents of departements or even regions, no MPs of Maghreb origin and Moslem confession. The purpose of this study is to analyze the mechanisms wich prevent the promotion of this elite, the most striking being at the national level, more precisely at the chambre des députés. The results confirm the absence of a real political will of the party leaders. This stems from the survival of attitudes and prejudices, particularly of ethno-confessional order, in the mind of influential personalities both from the right and the left. It is necessary to add that within the electorate, there are persistent and somehow latent discriminatory and racist conceptions deriving from the remembrance of the Algerian War with its psychological sides and biases concerning the presence of the Moslem religion. Prevailing cultural and/or political ideologies as well as the European values insist on diversity. But we are in front of a situation of blockage wich is complex and paradoxical. As for women coming from minorities, some have been appointed to govemment for complex strategic reasons. Although France is multiethnic, the current Chamber does not reflect the multicultural image of society. The effective representation of ethnic minorities stays a major challenge for the French Republic

Full textRabies causes more than 60,000 deaths worldwide each year, including 800 in Cambodia, where canine-mediated rabies virus circulates. Death occurs in nearly 100% of rabies cases, a disease which is nearly 100% avoidable by timely and adequate rabies post-exposure prophylaxis (PEP). Improving access to PEP in rural areas of endemic countries will spare human lives in the short term. This epidemiology PhD used the data collected in patients referred to the rabies prevention clinic and tested dogs at Institut Pasteur du Cambodge (IPC), Phnom Penh. After a baseline assessment of access to and obstacles to access timely and adequate PEP in Cambodia, this PhD aims to contribute to improving: 1/ geographical access and 2/ financial access to PEP for rural populations in Cambodia. We developed an original strategy to identify populations with a high risk of PEP noncompletion after a bite by a potentially rabid dog. This should help improve geographical access to PEP following the implementation in July 2018 of a peripheral rabies prevention center in Western Cambodia. This strategy can be applied to identify difficulties in accessing health services relevant to other health issues, under certain conditions. After patient callback and analysis of rabies deaths among those who did and did not complete the 4-sessions/1-month intradermal PEP regimen of their own accord, we were unable to demonstrate a difference in rabies mortality among patients who only received 3 vaccine sessions over the first week compared to those receiving at least 4 sessions/one month. Abridging the protocol to one week would reduce direct and indirect costs and the loss of income during PEP in the Capital. The adoption of this abridged regimen must be associated with a strengthened clinical monitoring system for at least 6 months following patients’ initial PEP.The work presented in this PhD has implications which reach beyond Cambodia: WHO recommends this new IPC regimen – the first approved one-week, abridged rabies PEP regimen – in its April 2018 guidelines

Full textLaunching the process of establishing ecotourism in developing countries requires today a real strategy to help decision makers to ensure the sustainability of tourism development in their territory. Furthermore, with regard to desert areas, there is urgency to build a model of implementation of ecotourism projects applicable in these vulnerable areas and based on the concept of ecotourism optimum developed by Jean-Pierre Lozato-Giotart (2003, p.306) that promotes synergy between their different components: actors, resources (natural and cultural), and visitors local communities ... that is to say, a "balance between recreation and conservation practices of the host territories". Creating a grid of indicators specific to desert areas ecotourism is an approach that could help build development programs based on the principles of ecotourism optimum. Also, the application of the concept of ecotourism in the optimum southwest of the Algerian Sahara, through the pilot project of ecotourism in the Daïra Charouine, located in Adrar, responds appropriately to local development strategies of the southern regions of Algeria, the vast majority is classified as poor, although their wealth in biodiversity and culture has already been identified. This case study opens a new vision to carry on thinking about sustainability indicators ecotourism for their effective implementation in the context of planning and project management in desert environments

Full textIn Africa, decentralization takes place in contexts that vary from country to country: the need to reform the Government following a crisis, the desire to establish local democracy to compensate for central or even dictatorial power, sometimes even the Government 's inability to provide basic socio-economic services such as health, education, drinking water, etc.In West Africa, decentralization was often accompanied by a redrawing of territories in the 1990s. Most West African countries have created three levels of local authorities: the Region, the Department (Cercle in Mali) and the Commune. This leads to a need for territory management and planning on several scales (inventory, monitoring of the environmental impact of development, sanitation, natural resource management, rural economic development, health, education, hydraulics and risk management). In the context of a growing need for information, development partners recognize the usefulness of the Geographic Information System (GIS) as a tool for decision making. The creation of different ministries in connection with geographic information in Mali requires pooling of skills centered on geomatics. Indeed, while each Institution and sectoral ministry has its own thematic data, their valuation is hampered by a high dispersion and disparity of geographical and cartographic data.How to share a common geospatial and territorial system across a town hall, a local authority, an NGO, the Government as well as other partners working on the same territorial? What territorial information strategy for a country like Mali?The aim of this thesis is to create, according to the concepts, methods, and technologies of current geography and statistics, a tool to support decision making in a context of overlapping responsibilities/actions and decentralization, designed to take a decisive step forward for the benefit of local territorial planning, by making coherent and available the geolocalized data necessary for an effective spatial planning policy. This strategic perspective implies going back to the distribution of powers, the ratio between free and paid software, participative information (societal, social, ethnic aspects, etc.) and the development of geographical information in Mali.An information strategy is in fact an essential prerequisite for any planning and development strategy. This thesis is an innovative project that will aim to provide answers on the implementation of such a strategy of multi-source and multi-stakeholder spatial information management in a developing country

Full textThis thesis examines the inflation dynamics and persistence in developing countries, especially in the UEMOA zone, highlighting the specificities of these economies. The first chapter, reveals that the inflation persistence degree, in these countries, is low which represents an asset to the monetary authorities. In Chapter 2, it was defined a more appropriate theoretical framework to analyze the inflation persistence in the countries of the sub-region. The approach allowed to demonstrate that the inflation persistence degree in these countries is not only dependent on monetary and exchange rate policies, but also negatively to the weight of local food sector in the economy. Chapter 3, analyzes the inflation differentials in the UEMOA member countries, by examining the β - convergence of inflation differentials. Estimations show that the inflation differentials are greatly reduced within the Union and they are highly persistent with the Euro zone. Chapter 4, is devoted to assessing the role of various factors and then uses a spatial panel specification to test the spillover effect between countries. Estimations indicate a predominance of global factors and contagion between countries whose magnitude depends on the weight of exports to other countries in the sub-region

In these days Video on Demand (VoD), one service that Internet protocol television (IPTV) provides, is very popular to watch the movie online. In VoD, videos playing in real time need to provide the quality of video and good bandwidth for the users. Amongst the access network solutions, EPON is the best to provide good bandwidth and quality of service at a low cost. The factor of increasing the demand for SDN from various industry and academic life separates the control plane from the data plane. In this research, we propose the local storage (LS) inside the optical network unit (ONU) for store the video for the end users based on TDMA-PON architecture to facilitate the direct multicasting for video on demand. SDN controller is used to control and manage the traffic based on Flow Table and Open Flow is used for communication with SD-OLT and SD-ONU. Simulation results show that the proposed architecture improve the quality of service (QoS) of system performance in terms of the delay time, jitter, system throughput and packet loss; and improve the efficiency of downstream bandwidth. Index terms- VoD, Local Storage, Zipf Law, TDMA-PON, SDN, QoS.

In recent years, wireless local area networks (WLANs) based on IEEE 802.11 standards [1]-[2] have been more and more popular all over the world due to their convenience of mobility and relatively low cost compared with cellular networks. As a result, more and more network applications are designed based on the advantages of WLANs, such as Voice over IP (VoIP), which is commonly used not only for social life between friends but also for cheaper communications. However, the call quality of VoIP depends strongly on the conditions of the network. When evaluating the VoIP capacity over IEEE 802.11 WLAN, most studies make some of the following assumptions: (1) there is only one type of stations, e.g., VoIP station, (2) the traffic of each station is saturated, i.e., the station always has a packet ready to be transmitted in the queue, (3) only the MAC access performance measures are taken into account, i.e., the performance measures of queue are ignored, (4) only the first moment performance measurements are considered, e.g., mean MAC access delay, (5) perfect channel condition, and (6) no capture effect. To be closer to real-life situations, first, we consider the multi-service WLAN, where there are three types of packets, i.e., VoIP, data, and ack packets. Second, we assume the queue size is finite and the packet arrivals at each station follow a Poisson process, i.e., we consider the non-saturated traffic scenarios. Third, we take account of the performance measures both at MAC access layer and at the queue. Fourth, not only the mean delay but also the delay jitter is taken into account when evaluating the VoIP capacity. We derive the analytical model of the considered multi-service WLAN, and study the effect of RTS/CTS, number of data stations, minimum contention window size, buffer size, channel error, and capture effect on VoIP capacity. The performance measures of interest are loss rate, mean delay, and delay jitter both in queue and in MAC access layer.

In the recent years, Voice over Internet Protocol (VoIP) is the most popular technology and will be a kind of killer application. Since Wireless Local Area network (WLAN) has a characteristic of mobility, people who use VoIP over WLAN can be more convenient. In the WLAN, IEEE 802.11e can support VoIP with better Quality of Service (QoS). However, 802.11e doesn’t consider the time-varying condition of wireless channel. It needs an adaptive mechanism to complement it. Thus, in this thesis, we implement a cross-layer adaptive VoIP application which can use a suitable codec according to current channel condition. Besides, we also implement a policy-based 802.11e WLAN to protect the right of user who has applied real-time services. The experiment results show the proposed cross-layer adaptive VoIP application can archive better performance than the fixed one.

In this era of globalization, many companies choose to develop abroad, even establish an oversea subsidiary, to seek for better opportunities. However, they meet with different local conditions in different host countries, including cultural and environment. Therefore, these subsidiaries are encouraged to set up their own local relations network. In the past studies, although the concept of network resources is used to explain this type of partnership in local area, there is still less research about impact of institutional environment on the expansion of multinational companies in overseas subsidiaries. This study is intended to explore the relationship between range and strength of a subsidiary’s local network, and the performance of the subsidiary. Meanwhile, the operating of overseas subsidiaries often affected by the local institutional environment. So this study also includes the local institutional voids as a moderating variable. In theoretical part, we start with the view of network resources based and extend to the institutional voids caused by the incomplete institutional system in some countries. At the same time, we combine some relevant studies and the original database of the “Investigation on Foreign Investment in Manufacturing Industry” (2006) as the source of our data. After screening based on our study aim, 274 multinational companies that established their subsidiaries in China and Southeast Asia has been chosen for analyzing by hierarchical regression model. The results of this study show that when the local network range is wider and the strength is stronger, the performance of the subsidiaries will be improved. However, the exist of institutional voids will weaken the positive relationship between local network and subsidiary performance. Thus it can be seen that the development of subsidiaries can be improved by having local network resources, especially when the connection is wider and stronger. Besides, this study uses institutional voids as moderating variables, also helps to understand the importance of local conditions on subsidiaries performance. This study also supplements some results which were lacking in the past study, and also provides some reference for the industry.
