Résumé :

Analysis and proper design of power distribution networks (PDNs) are critical steps in developing modern electronic systems. Parallel-plate structures with vias are the core components of PDN configuration at any scale of system implementation from chip to package and printed circuit board. Voltage fluctuations induced by vias with carrying time-varying currents are interpreted as power/ground noise. In this thesis, this type of noise is quantified by two fast prediction methods, i.e. using radial transmission line theory and resonant cavity analysis. A number PDN structures containing single or multiple parallel-plates and vias are simulated using the developed analytical models. These models are portable to the commercial circuit simulators, provide a fast means of PDN analysis and enable global system simulations. Suppression of power/ground noise by using discrete decoupling capacitors and differential signalling is investigated using the developed models. The validity of the models is tested against full-wave simulations and prototype measurements. Improvement of power integrity is also studied by using a uniplanar EBG structure in a parallel-plate stack-up. The main challenge in employing EBG structures in compact low frequency designs is the relatively large footprint of the EBG unit cell. This thesis reviews two techniques for miniaturization of a uniplanar EBG and demonstrates their efficacy through full-wave simulations.
L'analyse et la conception appropriée du réseau de distribution d'énergie (RDE) sont des étapes critiques lors du développement de systèmes électoniques modernes. La composante principale d'un RDE est une structure de plaques parallèles avec vias, et ce à toutes les étapes de l'implémentation, du désign circuit à la carte imprimée. Les fluctuations du voltage induites par le courant variable qui transite par les vias sont typiquement interprétées comme du bruit sur la source de tension ou la mise à la terre. Dans la présente thèse, ce type de bruit est quantifié à l'aide de deux méthodes rapides de prédiction. Celles-ci sont la théorie radiale des lignes de transmissions ainsi que l'analyse des cavités résonnantes. Plusieurs structures RDE contenant une ou plusieurs plaques parallèles combinées à des vias sont simulées à l'aide des modèles analytiques présentés. Ces modèles sont facilement transférables vers des simulateurs de circuits commerciaux, ce qui fournit un moyen rapide d'effectuer l'analyse du RDE dans une simulation globale. Nous analysons également la suppression de bruit de source/mise à la terre effectuée à l'aide de condensateurs discrets de découplage ou à l'aide de signalement différentiel. Les modèles sont validés par comparaison avec des simulations à onde complète et des mesures sur prototype. Nous étudions les améliorations à l'intégrité de la source de puissance à l'aide de structure EBG dans un empilage de plaques parallèles. Le défi principal relié à l'emploi de structures EBG dans un désign compact et basse fréquence est dû à la grande taille des unités EBG. Nous passons en revue deux techniques pour miniaturiser un EBG uniplanaire et démontrons leur efficacité à l'aide de simulation à onde complète.

The adoption of commercial off the shelf networks, such as Ethernet, FireWire and FibreChannel, within the avionics community has dramatically changed the architecture of avionics busses and instrumentation networks. Higher bandwidth links and unified interconnects simplify existing infrastructure and wiring. But due to their point-to-point nature, networking topologies are fundamentally different from systems built on legacy bus technologies such as CAIS and MIL-STD-1553. Switched networks and ring topologies pose various challenges for the implementation of network monitoring hardware, and affect the design of bus monitors and distributed data acquisition systems. This paper discusses some of these issues. In particular we address deployment issues, architectural choices such as pass-through versus tap approach, as well as handling of bandwidth requirements and complex communication protocols. We illustrate on the basis of a FireWire monitoring system how these obstacles have been overcome for one given application.

Résumé :

The appropriate analysis of the response of distribution networks against Lightning Electro Magnetic Pulse (LEMP) – originated by nearby strikes – requires the availability of accurate coupling models in order to reproduce the real and complex configuration of distribution systems. The above models represent a fundamental tool for estimating the number of protective devices and their most appropriate location in order to guarantee a given minimum number of flashovers and outages per year. When dealing with real networks, such an optimization could require huge computational efforts due to the vast number of power components and feeders. This thesis thoroughly analyzes many of the possible engineering simplifications that, without losing accuracy, can be adopted in the statistical evaluation of the lightning performance of distribution networks in order to limit computational times. Particular attention is devoted to the effect of the ground conductivity on the LEMP and on the line parameters; two new analytical expressions for the evaluation of the inverse Laplace transform of the ground impedance matrix elements of multiconductor overhead lines are derived. The first expression is the inverse Laplace transform of Sunde’s logarithmic formula and is given in two equivalent forms. The second expression is the inverse Laplace transform of Sunde’s general integral expression. Finally, a procedure able to evaluate the lightning performance of a real medium-voltage distribution network, which includes several lines, transformers and surge protection devices is developed and proposed for the analysis of some real cases. Such a procedure allows inferring the characteristics of the statistical distributions of lightning-originated voltages at any point and phase of the network. The analysis aims at assessing the expected mean time between failures of transformers caused by both direct and indirect lightning strikes.

Résumé :

We investigate spectral-efficient design and develop novel schemes to improve spectral efficiency of the modern wireless communications networks. Nowadays, more and more spectrum resources are required to support various high-data-rate applications while spectrum resources are limited. Moreover, static allocation and exclusive access in current spectrum assignment policy caused a lot of licensed spectrum bands to be underutilized. To deal with the problem, cognitive radio (CR) has been developed, which allows unlicensed/secondary users to transmit with licensed/primary users as long as the former ones do not generate intolerable interference to the latter ones. The coexistence of users and networks requires careful and dynamic planning to mitigate interference. Otherwise, the network performance will be severely undermined. We study both spectrum sensing and spectrum access techniques and propose several transmit schemes for different types of cognitive ratio networks, including spectrum overlay and spectrum underlay systems. The proposed algorithms can improve spectral efficiency of the networks efficiently and have potentials to be used in future wireless communications networks.

Résumé :

This thesis contributes new knowledge to an understanding of how people's social networks in the early modern theatre shaped the drama they created. By studying the lives of people working in the theatre, attending to biographical details not hitherto fully considered, it recasts received narratives of theatre history. Where theatre historians often tell stories of competition and combat, it finds evidence too for considerable amity across webs of relationships that are here called 'social networks'. This thesis offers new biographical facts about life events for the actor Richard Bradshaw and the actor-writer William Rowley. In addition, it endeavours to change the way historians think about collaborative playwriting in the period. Based on quantitative analysis, this thesis shows the rates of collaboration to be about half the rate of heretofore accepted estimates. Chapter One considers in detail the narratives that historians construct about the early modern theatre and the problems associated with them. It reviews the various classes of evidence used in later chapters and the uses to which such evidence can reasonably be put. Chapter Two explores an industry in expansion in the 1590s, re-examining the well-known duopoly narrative and reconsidering the various professional pursuits and diverse residences of actors and playwrights in the period. Chapter Three looks at the following decade, the 1600s, and the re-emergence of troupes of boy actors into an expanding and stabilising industry. Chapter Four shows how collaborative writing, though prevalent, was not as frequent as is usually thought; it also shows stark differences in rates of staging collaborative drama between companies. Each chapter closes with a biographical case study of a theatre person whose life is considered in terms of their social network. An examination of such networks is then used to reshape the way we understand events in their life and broader currents that involve the entire early modern theatre industry. Thinking about who interacted with whom and why adds a new layer of complexity to our collective model of how this entertainment industry produced the period's extraordinary proliferation of highly valued plays.

Résumé :

The reconstruction of news flows in early modern Europe is a research topic spanning across media, time and space. Quantitative methods can help with semi-automatic techniques applied to the massive study of intertextuality. Sharing Brendan Dooley's idea that “the first step in tracing news flows is to compare typical texts”, we are developing algorithms to automatically find textual borrowings to reconstruct these flows. Our corpus is made of both handwritten and printed newsletters, which allows us to specifically study inter and intra medium interactions. Texts are all in Italian, yet the language is not standardised and varies greatly across different sources. We thus need to approach comparisons with fuzzy language-independent methods, in fact relevant for early modern texts in general. Our techniques are mixed and tailored for each medium type: OCRed texts extracted from printed sources are compared to manually constructed graphs of keywords from handwritten sources. We use a multi layer graph representation, which keeps track of named entities, quantities and other meaningful informations, linking them according to agentivity or specification, aiming at reconstructing the signature of each news. Different representations are then compared with ad hoc techniques, among which we profitably use vector and matrix similarity, string kernels originally developed for protein classification, and more traditional n-gram methods. The research is mostly experimental and methodological, with a view on the potential reuse and expansion of the methods developed.

Cataloged from student-submitted PDF version of thesis.
Includes bibliographical references (pages 77-80).
This thesis first presents a measurement toolkit, Mahimahi, that records websites and replays them under emulated network conditions. Mahimahi improves on prior record-and-replay frameworks by emulating the multi-origin nature of Web pages, isolating its network traffic, and enabling evaluations of a larger set of target applications beyond browsers. Using Mahimahi, we perform a case study comparing current multiplexing protocols, HTTP/1.1 and SPDY, and a protocol in development, QUIC, to a hypothetical optimal protocol. We find that all three protocols are significantly suboptimal and their gaps from the optimal only increase with higher link speeds and RTTs. The reason for these trends is the same for each protocol: inherent source-level dependencies between objects on a Web page and browser limits on the number of parallel flows lead to serialized HTTP requests and prevent links from being fully occupied. To mitigate the effect of these dependencies, we built Cumulus, a user-deployable combination of a content-distribution network and a cloud browser that improves page load times when the user is at a significant delay from a Web page's servers. Cumulus contains a "Mini-CDN"-a transparent proxy running on the user's machine-and a "Puppet": a headless browser run by the user on a well-connected public cloud. When the user loads a Web page, the Mini-CDN forwards the user's request to the Puppet, which loads the entire page and pushes all of the page's objects to the Mini-CDN, which caches them locally. Cumulus benefits from the finding that dependency resolution, the process of learning which objects make up a Web page, accounts for a considerable amount of user-perceived wait time. By moving this task to the Puppet, Cumulus can accelerate page loads without modifying existing Web browsers or servers. We find that on cellular, in-flight Wi-Fi, and transcontinental networks, Cumulus accelerated the page loads of Google's Chrome browser by 1.13-2.36×. Performance was 1.19-2.13× faster than Opera Turbo, and 0.99-1.66× faster than Chrome with Google's Data Compression Proxy.

Résumé :

Distribution system plays a significant role in the overall electrical power system due to its impact on electricity costs, reliability as well as security of supplied energy. Optimal development planning of modern distribution system is mainly required to satisfy continuous change in customer demands and generations in a cost-effective manner, utilizing the available smart solutions. All these aspects need to be addressed in modern distribution planning methodology that can be applied today in real-life. Review has shown that there are no distributions planning models that adequately model security of supply of radially operated networks. Moreover, the optimal development planning models still do not consider multiple operating regimes, which has become a necessity due to connection of low carbon technologies. Numerous techniques published on this subject tend to ignore the regulations and planning standards that must be complied during system development, resulting in methodology that is not in-tuned with business practices. Furthermore, a comprehensive model that integrates all major components of todayâs real-life distribution planning is still lacking, even though many of them have been addressed individually. In this thesis, integrated planning methodology for development of distribution system is proposed, incorporating utility practices in the UK. The overall methodology built on two independent stages, investment stage and operation stage. The operation stage is further cast into two sub-stages, quality of supply planning and minimization of operation costs planning. The overall planning methodology incorporates the novel probabilistic decision tree concept for distribution system planning to consider probable network uncertainties. The first model which is the investment stage determines the new construction and reinforcement of circuits and switchgear, along with circuit decommissioning. Multiple operating regimes due to fluctuation in generation and load profiles are considered, in addition to explicit modelling of N-1 security constraint according to P2/6 planning standards. The quality of supply planning determines the allocation of switchgear and its automation to maximise the reliability benefits from the regulatory incentive regime. Finally, the operation model determines the optimal network configuration that minimises the total operation costs of distribution system. The final outputs are list of cables and switchgear for construction, reinforcement, and decommission, benefits harvested due to quality of supply investments on switchgear, optimal network running arrangement, etc. These studies have proven to be important in formulating effective strategies for development of distribution system, in compliance to the planning standards and resulted in higher network operation capabilities.

Texte intégral

Résumé :

This thesis argues that social debt profoundly transformed the environment in which literature was produced and experienced in the early modern period. In each chapter, I examine the various ways in which social debt affected Renaissance writers and the literature they produced. While considering the cultural changes regarding patronage, love, friendship, and debt, I will analyze the poetry and drama of Ben Jonson, Lady Mary Wroth, William Shakespeare, and Thomas Middleton. Each of these writers experiences social debt in a unique and revealing way. Ben Jonson's participation in networks of social debt via poetry allowed him to secure both a livelihood and a place in the Jacobean court through exchanges of poetry and patronage. The issue of social debt pervades both Wroth's life and her writing. Love and debt are intertwined in the actions of her father, the death of her husband, and the themes of her sonnets and pastoral tragicomedy. In Shakespeare’s The Merchant of Venice (c. 1596), Antonio and Bassanio’s friendship is tested by a burdensome interpersonal debt, which can only be alleviated by an outsider. This indicated the transition from honor-based credit system to an impersonal system of commercial exchange. Middleton’s A Trick to Catch the Old One (1608) examines how those heavily in debt dealt with both the social and legal consequences of defaulting on loans.

Résumé :

ABSTRACT High-Speed Mobile Networks for Modern Farming and Agricultural Systems J.Santos Najar-Ramirez High-speed mobile networks are necessary for agriculture to inventory individual plant health, maximize yield and minimize the resources applied. More specifically, real-time information on individual plant status is critical to decisions regarding the management of resources reserved and expended. This necessity can be met by the availability of environmental sensors (such as humidity, temperature, and pH) whose data is kept on storage servers connected to static and mobile local area networks. These static and mobile local area networks are connected to cellular, core and satellite networks. For instance, agricultural experts remotely working on vast acreage farms from business offices or while traveling can easily connect their notebook computers and other portable devices to these networks in order to check farm status, send email, read industry news or arrange a visit to neighbor farms or suppliers. Today, several mobile phone companies offer broadband service with 2Mbps downlink in rural and dense urban areas, however, they do not typically exist in farm areas. Although these networks (such as 802.11ac/n, 3G, 4G, etc) are significant achievements, they do not meet the projected needs of the agricultural industry. The present use model of high-speed networks for email and multimedia content, together with agriculture’s expected intensive use of real-time plant and environmental condition monitoring, with statistics/plots and real-time high resolution video, necessitates a highly integrated and highly available networked system. For agricultural experts, attentive to market needs, seamless high-speed wireless communication ‘anywhere, anytime at any speed’ is critical to enhancing their productivity and crop yields.

Résumé :

While the benefits of analysing social networks within the wider humanities are becoming more accepted, very little work of this kind has been done in medieval studies. This thesis seeks to begin to fill this lacuna by considering the advantages of examining historical moments through the lens of ‘network’. Focusing on the later medieval world (in particular c.1300-1520), but also drawing on parallel evidence from the modern day, it demonstrates how the paradigm of ‘network’ allows a more nuanced reading of, predominantly literary, historical moments, which in turn reveals a deeper understanding of collective social thinking and behaviour. This new methodological approach is threefold, drawing on analytic tools from various disciplines. It blends historical contextual investigation with literary analysis, and frames the results in the sociological and anthropological theories of belonging, exchange, and play. The thesis is structured around four case studies, each of which demonstrates a particular form of network formation, and also shows how far these networks reflect their respective cultural milieus and influences. Three medieval chapters focus on what I term ‘literary networks’, a concept ripe for network analysis thanks to the highly participatory nature of medieval literature, and thus theoretically comparable to modern networks based around information exchange. Across the thesis, instances of formal, informal, and virtual networks are considered from medieval France and England, as well as the twenty-first century West. This combination of interdisciplinary method and structure allows innovative new readings of underappreciated sources, whilst also highlighting a transhistorical continuum of universal appeals to social networks: namely, the satisfaction of the human need to belong, the facilitation of competitive play, and the opportunity to acquire social capital and build reputations. This investigative synthesis between medieval material and more modern network evidence reveals that, while realised through unrecognisably altered technologies and experiencing some resultant disruptions, these fundamental appeals of social network membership, in part, remain constant between the two periods.

Résumé :

In recent years, the theoretical approaches of social network analysis have already made an impact in the historical field. Specifically, the Republic of Letters, the pan-European intellectual community of the sixteenth, seventeenth and eighteenth century, has been the subject of a rich interdisciplinary historiography for the past few decades. But although this letter-writing community has attracted more and more scholarly attention in conjunction with a global turn in the practice of the digital humanities, the study of networks in historical research remains a field in its infancy. It has yet to establish its methodology, its ontologies, the best digital tools, and even the language by which we invoke technical processes in the study of early modern history. Rarely do historical studies offer an actual implementation and testing of how the mathematical tools employed by network scientists offer valuable ways of understanding and exploring the past. Most studies underline the potential utility of network metrics, but leave their exploration for future research. To add to this conceptual murkiness, the use of digital tools is often looked upon in a suspicious way, considered to be too simplistic and hence unsuitable to deal with the complexity and uncertainty of historical sources. There is, as underlined by Ruth Ahnert and Sebastian Ahnert, “still much work to be done before statistical methods are embedded within the literary historian’s toolbox”. We need, therefore, to continue to sharpen our digital tools and experiment with network models that give nuance, subtilty and detail to historical data. This study attempts to take up this challenge and to demonstrate how social network analysis enables us to advance the cause of historical inquiry. It will address this challenge by exploring the ways in which early modern scholars capitalized on opportunities in the social structure to which they were connected. Accordingly, much of the essence of this study focuses on methodology rather than historical narrative. We might even say that this study has an experimental character in nature. Specifically, we will take a look at how early modern networks were actively and consciously constructed, modified, questioned and navigated by early modern scholars. They were constantly monitoring their interactions with one another in making decisions. On the one hand, early modern scholars were expected to contribute towards the achievement of the collective goals of the Republic of Letters – the bonum commune – that rested on the imperative of sharing knowledge without frontiers. Nevertheless, they had to deal with many tensions and inefficiencies at a time in which the freedom of communication was not always guaranteed. These tensions ranged from restrictions imposed by the Inquisition to scholarly rivalries, jealousy and competition. As a consequence, it seems that the citizens of the Republic of Letters often found themselves between extremes, struggling to find a balance in dealing with these tensions. They had to strategically negotiate between open and closed circles in their networks, between friendly and hostile relationships and between openness and secrecy in their communication. [...]

Résumé :

Inferring and anticipation of genetic networks based on experimental data and environmental measurements is a challenging research problem of mathematical modeling. In this thesis, we discuss gene-environment network models whose dynamics are represented by a class of time-continuous systems of ordinary differential equations containing unknown parameters to be optimized. Accordingly, time-discrete version of that model class is studied and improved by using different numerical methods. In this aspect, 3rd-order Heun&rsquo
s method and 4th-order classical Runge-Kutta method are newly introduced, iteration formulas are derived and corresponding matrix algebras are newly obtained. We use nonlinear mixed-integer programming for the parameter estimation and present the solution of a constrained and regularized given mixed-integer problem. By using this solution and applying the 3rd-order Heun&rsquo
s and 4th-order classical Runge-Kutta methods in the timediscretized model, we generate corresponding time-series of gene-expressions by this thesis. Two illustrative numerical examples are studied newly with an artificial data set and a realworld data set which expresses a real phenomenon. All the obtained approximate results are compared to see the goodness of the new schemes. Different step-size analysis and sensitivity tests are also investigated to obtain more accurate and stable predictions of time-series results for a better service in the real-world application areas. The presented time-continuous and time-discrete dynamical models are identified based on given data, and studied by means of an analytical theory and stability theories of rarefication, regularization and robustification.

Résumé :

Although the overall levels of harmonics in modern power supply systems are in most of the practical cases still below the prescribed tolerance limits and thresholds (e.g. these stipulated in [IEC 61000-3-2 and 61000-3-12]), the sources of harmonics are constantly increasing in numbers and are expected to increase even more in the future. Some of the examples of modern non-linear power electronic (PE) devices that are expected to be employed on a much wider scale in LV networks in the future include: light-emitting diode (LED) lamps, switched-mode power supplies (SMPS'), electric vehicle battery chargers (EVBCs) and photovoltaic inverters (PVIs), which are all analysed in this thesis. The thesis first reviews the conventional harmonic analysis methods, investigating their applicability to modern PE devices. After that, the two most widely used forms of harmonic models, i.e. component-based models (CBMs) and frequency-domain models (FDMs), are applied for modelling of the four abovementioned types of modern PE devices and their models are fully validated by measurements. The thesis next investigates the impact of supply voltage conditions and operating modes (e.g. low vs high operating powers) on the device characteristics and performance, using both measurements and developed CBMs and FDMs. The obtained results confirm that both supply conditions and operating modes have an impact on the characteristics of most of the considered PE devices, which is taken into account in the developed models and demonstrated on a number of case studies. As the next contribution, the thesis proposes new indices for the evaluation of current waveform distortions, allowing for a separate analysis of contributions of low and high frequency harmonics and interharmonics to the total waveform distortion of PE devices. As the modern PE devices are normally based on high-frequency switching converters or inverters, the impact of circuit topologies and control algorithms on their harmonic emission characteristics and performance is also investigated. Special attention is given to the operation of PE devices at low powers, when there is a significant increase of current waveform distortion, a substantial decrease of efficiency and power factors and when input ac current might lose its periodicity with the supply voltage frequency. This is analysed in detail for SMPS', resulting in the proposal of a new methodology ("operating cycle based method") for evaluating overall performance of PE devices across the entire range of operating powers. Finally, a novel and simple hybrid harmonic modelling technique, allowing for the use of both time-domain and frequency-domain models in the same simulation environment, is proposed and illustrated on the selected case studies. This is accompanied with a frequency-domain aggregation approach, which is applied in the thesis to investigate the impact of increasing numbers of different types of modern PE devices on the LV network. The implementation of the developed hybrid harmonic modelling approach and frequency-domain aggregation technique is demonstrated on the example of a typical (UK) urban generic LV distribution network and used for the analysis of different deployment levels of EVs and PVIs. The presented harmonic modelling framework for individual PE devices and, particularly, for their aggregate models, fills the gap in the existing literature on harmonic modelling and characterisation of modern PE devices, which is important for the correct evaluation of their harmonic interactions and analysis of the impact of their large-scale deployment on the overall network performance.

Modern telemetry networks require the use of efficient domain-specific protocols at the transport, network, and routing layers. However, the existing end-devices and services are based on legacy protocols such as TCP/IP. This necessitates translation between the legacy and aeronautical protocol. In this paper we propose an efficient translation mechanism with the help of gateways at the telemetry network edges.

Texte intégral

Résumé :

This dissertation investigates Chinese Muslim (Hui) intellectual currents from the late Qing dynasty to the early years of the Communist Republic, 1908–1957. By analyzing a vast number of Muslim reformist journals, Chinese translations of Islamic sources, and diaries/memoirs of intellectuals who were connected to other zones of the Islamic world, I examine the process by which reformists sought to redefine Chinese Muslim identity and revive “true principles of Islam”—both in negotiation with the Chinese state and in conversation with local and transnational intellectual currents. In particular, this dissertation considers the ways in which intellectuals struggled to “awaken” Chinese Muslims so as to transform their past identity as Muslim subjects of the Qing Empire into “politically conscious and active” citizens of the Chinese Republic. Chinese Muslims were defined either as a religious community or an ethnic group (minzu), and this debate occupied the minds of reformist intellectuals in this period, the topic of the first two chapters. How it was settled would determine the political, social, and religious status of the Muslim community in China, where definitions of nation and ethnicity/race were constantly reassigned. Debates concerning Muslim integration into China hinged on their connection to the global Muslim community (umma). Newly introduced technologies of travel and communication, such as the steamship and print, facilitated Chinese Muslims’ participation within transnational and cross-confessional networks. I argue that it was through the selection, appropriation, and adaptation of ideas from the prominent centers of the Islamic world that these intellectuals navigated a path of integration in the Chinese context that did not put their distinct Muslim identity at risk. From these diverse sources, they were determined to find solutions to the challenges they faced in China—whether posed by the hegemonic discourse of the Nationalist Party or the iconoclastic New Culture Movement. In successive chapters, I focus on the intellectual connection of Chinese Muslims to the Kemalist secularism of Turkey, the Ahmadi movement of India, and Egyptian reformist currents. Thus, I demonstrate how a seemingly “peripheral” Muslim community in the Far East participated in complex transnational networks at a critical moment of transformation.

Résumé :

The enormous concerns of climate change and traditional resource crises lead to the increased use of distributed generations (DGs) and electric vehicles (EVs) in distribution networks. This leads to significant challenges in maintaining safe and reliable network operations due to the complexity and uncertainties in active distribution networks, e.g., congestion and reliability problems. Effective congestion management (CM) policies require appropriate indices to quantify the seriousness and customer contributions to congested areas. Developing an accurate model to identify the residual life of aged equipment is also essential in long-term CM procedures. The assessment of network reliability and equipment end-of-life failure also plays a critical role in network planning and regulation. The main contributions of this thesis include a) outlining the specific characteristics of congestion events and introducing the typical metrics to assess the effectiveness of CM approaches; b) proposing spatial, temporal and aggregate indices for rapidly recognizing the seriousness of congestion in terms of thermal and voltage violations, and proposing indices for quantifying the customer contributions to congested areas; c) proposing an improved method to estimate the end-of-life failure probabilities of transformers and cables lines taking real-time relative aging speed and loss-of-life into consideration; d) quantifying the impact of different levels of EV penetration on the network reliability considering end-of-life failure on equipment and post-fault network reconfiguration; and e) proposing an EV smart charging optimization model to improve network reliability and reduce the cost of customers and power utilities. Simulation results illustrate the feasibility of the proposed indices in rapidly recognizing the congestion level, geographic location, and customer contributions in balanced and unbalanced systems. Voltage congestion can be significantly relieved by network reconfiguration and the utilization of the proposed indices by utility operators in CM procedures is also explained. The numerical studies also verify that the improved Arrhenius-Weibull can better indicate the aging process and demonstrate the superior accuracy of the proposed method in identifying residual lives and end-of-life failure probabilities of transformers and conductors. The integration of EV has a great impact on equipment aging failure probability and loss-of-life, thus resulting in lower network reliability and higher cost for managing aging failure. Finally, the proposed piecewise linear optimization model of the EV smart charging framework can significantly improve network reliability by 90% and reduce the total cost by 83.8% for customers and power utilities.

Résumé :

As an output of the HERA Travelling Texts project, created with the aim of uncovering the realities of women’s literary culture on the fringes of Europe during the long nineteenth century, this study was conceptualised to find out more about the networks of women writers in Spain around 1900, using the digitised corpuses of contemporaneous periodicals as the primary source material. Each chapter of the study centres on a particular periodical, which is used as the starting point for the community of writers and readers, both real and imagined. This thesis looks at the realities of the literary culture for creative women in the late nineteenth century-early twentieth century, exploring the strategies used by women (and men) to support each other in their literary endeavours, how they took inspiration and courage from each other, how they promoted their own names, and how they were received by wider society. The study will also focus on the transnational nature of this literary culture, looking at how women of different nations influenced each other’s work, with a view to understanding more about how cultural change takes place. Finally, this thesis hopes to persuade the reader that the periodical is a rich and under-utilised resource for discovering more about the lives of women writers and their network of relationships.

Résumé :

This thesis reconsiders a highly mobile form of portraiture, the early modern portrait medal, by examining its active role in the intersubjective relations and networks of diverse individuals. By attending to three distinct moments between 1400 and 1700, the mutability of the role of medaglie – the early modern term for portrait medals, antique coins, and contemporary coinage – is made clear. Examining the representation of medaglie in painted and printed portraits during these years allows for a comparative consideration of the medaglie’s role in historically contingent forms of intersubjectivity. Botticelli’s Young Man Holding a Medal (1473) brings to light the way that medals mediated the intimate and ambiguous interdependence that characterized courtly, middle class, and humanist culture in the fifteenth century. Through their gift exchange and the demand of the face, the portrait medal is shown to be a key player in courtly society that not only reflects the power of the ruler over his subjects, but also the interdependent nature of this power. Titan’s Portrait of Jacopo Strada (1567-8) redirects the discussion of the intimate encounter to the shifting nature of collections of medals, as they became increasingly large and regimented. The medaglie in Strada’s portrait speak to key social attributes and the changing sites where these attributes were founded. Finally, the engraved portrait of Ferdinando Cospi in his museum in Bologna (1677) thematicizes an increased distancing between the subject and object in seventeenth century galleries and museums. This distancing is complicated by the continued implication of interdependence in practices of gift giving that support claims to allegiance made by Cospi. Medaglie most often circulated according to the complex and often hierarchical conditions of friendship that dominated intersubjective relationships in many early modern networks. However, possible strangerhood and equality of membership also characterize some networks. This shift prompts consideration of the degree to which medaglie were implicated in processes of public formation. The temporally extended nature of this study and the intermediality of the representation of medaglie suggest that, as the medaglie themselves were implicated within forms of sociability, they could be understood as constitutive of proto-publics.

Résumé :

In this thesis connections between messages on the public wall of the Russian social network Vkontakte are analysed and classified. A total of 1818 messages from three different Vkontakte groups were collected and analysed according to a new framework based on Halliday and Hasan’s (1976) research into cohesion and Simmons’s (1981) adaptation of their classification for Russian. The two categories of textuality, cohesion and coherence, describe the linguistic connections between messages. The main aim was to find out how far the traditional categories of cohesion are applicable to an online social network including written text as well as multimedia-files. In addition to linguistic cohesion the pragmatic and topic coherence between Vkontakte messages was also analysed. The analysis of pragmatic coherence classifies the messages with acts according to their pragmatic function in relation to surrounding messages. Topic coherence analyses the content of the messages, describes where a topic begins, changes or is abandoned. Linguistic cohesion, topic coherence and pragmatic coherence enable three different types of connections between messages and these together form a coherent communication on the message wall. The cohesion devices identified by Halliday and Hasan and Simmons were found to occur in these texts, but additional devices were also identified: these are multimodal, graphical and grammatical cohesion.

Texte intégral

Résumé :

A Nazi news editor declared in 1934 that there were indefinable "magic connections" between news and politics. This dissertation demystifies those links between communications and society. An untold story of news networks lies behind the media sources that we mine constantly as historians. In particular, news agencies, the essential bottleneck of news supply, remain obscured behind the newspapers printing their reports. This study explores why news agencies became the intuitive modern form of news collection and dissemination and how they functioned as a central locus for tussles over the creation of news from events, the limits of government or business control over news, and the role of technology in revising communications infrastructures. 1905 to 1945 represented the zenith of German faith in news agencies’ ability to overturn the existing world order. Along with industrialists and academics, politicians and bureaucrats thought that news agencies could change not only Germany’s role in global communications, but politics, economics, and society too. Coupled with technical advances in wireless telegraphy, news agencies seemed the best means to improve Germany’s international reputation, boost foreign trade, and create societal cohesion at home. News agencies seemed the key to controlling public opinion as well as to creating global news networks conducive to Germany. This news agency consensus united German elites of all political stripes in the belief that news agencies provided an ideal outlet to solve political, social, and economic problems. While such schemes did not always succeed, German news agencies often altered the modern infrastructure of global communications. They briefly achieved media dominance on the oceans, challenged Reuters’ and Agence Havas’ control of European news, and became a leading supplier of news to South America and East Asia in the Nazi period. This work illustrates the interdependence of communications and history by integrating approaches from business history, communications studies, sociology, book history, and the history of technology. It shows the spread and success of German news at a moment when news agencies played a central and underappreciated role in the negotiation of a new relationship between politics, economics, and society in first half of the twentieth century.

Résumé :

This thesis offers a reappraisal of the early modern history play, locating the genre in the participation of its producers and users, and concentrating in particular on the repertory companies, stationers, and patronage networks that have shaped historical drama in England. While previous accounts have tended to focus on Shakespeare’s English histories, as catalogued in the First Folio, and used these plays to define the genre retrospectively, this study recognizes the classificatory elusiveness of terms such as ‘history’ and the diverse ideas of genre and history that were circulating during the period. This study prioritizes a selection of plays and production networks from the Elizabethan, Jacobean, and Caroline periods to examine local engagements that more fully reflect the shifting position and utility of history plays on stage and in print. In interrogating assumptions about what constitutes a history play, this thesis examines five chronological case studies that suggest the importance of a more inclusive understanding of ‘history’, demonstrate how theatrical companies, publishers, and patrons have influenced the history play, and provide evidence of the synchronic readings that this study aims to privilege. Chapters are devoted to production networks involving Thomas Creede and Queen Elizabeth’s Men, Andrew Wise and the Chamberlain’s Men, and the Herbert family and the King’s Men, as well as to the agency of individual stationers, including Nathaniel Butter, and censoring authorities, such as the Master of the Revels. Taken together, these case studies draw attention to the political valencies of history plays as they are negotiated by their agents of production and to wider issues of play performance, publication, and patronage. Moving away from ideas of generic fixity and defined canons, this study positions the history play through networks of participation and influence that reveal the varied ways in which the past was negotiated.

ENGLISH ABSTRACT: The Internet is coming more and more into focus of national and international legislation. Especially with regard to copyright law, the rapid growth of the Internet, its global character, its novel technical applications and its private and commercial use by millions of people makes the control over a work complicated and raises copyright problems all over the world. Present legislation is therefore challenged to avoid gaps in the law. Considering the rapid growth of online providers and users in South Africa, it is likely that copyright disputes with regard to the Internet will evolve here soon. In this dissertation, the "world" of the Internet and its lawfulness with regard to existing South African copyright law will be examined. The examination tries to establish whether South African copyright law is able to cope with the present Internet problems and whether it leads to reasonable results. The first chapter of this dissertation will give an overview of the basic principles of the Internet, including the history, development and function of the Internet. Furthermore the changing aspects by means of diqital technology will be discussed. Because the global character of the Internet lead to "international" infringements, governments are considering the prospect of reaching international accord on the protection of intellectual property in the digital era. In chapter two, the present international harmonisation of copyright law will be introduced. Especially the quick adoption of the World Intellectual Property Organisation Treaties in December 1996 demonstrated that an international realisation for a call for action is existing. In chapter three, the application of South African copyright law with regard to the Internet will be discussed. First, it will be examined if a digital work on the Internet is protected in the same way as a "traditional" work. Second, the various rights of the copyright holder are discussed in connection with the use of a work on the Internet. Third, the potential application of the exclusive rights of the copyright holder to various actions on the Internet, such as caching, Web linking and operating an online service will be discussed. The Internet is a worldwide entity, and, as such, copyright infringement on this system is an international problem. The scenario of global, simultaneous exploitation of works on the Internet conflicts sharply with the current system of international copyright protection, which is firmly based on national copyright laws with territorial effects. Section four provides therefore an overview of the applicable law on an international net and analyses the necessity and borders of protection.
AFRIKAANSE OPSOMMING: Nasionale en internasionale wetgewing fokus in In toenemende mate op die Internet. Die versnelde groei van die Internet, sy wêreldkarakter, sy nuwe tegnologiese aanwendings en sy private en kommersiële gebruik deur miljoene mense maak beheer oor In werk baie gekompliseerd en skep veral outeursregprobleme regoor die wêreld. Wetgewing soos dit tans is, word dus uitgedaag om die leemtes in die reg te ondervang. Gegewe die vinnige groei van gekoppelde verskaffers en gebruikers in Suid-Afrika, is dit waarskynlik dat - outeursreggeskille met betrekking tot die Internet binnekort ook hier gaan ontwikkel. In hierdie verhandeling gaan die "wêreld" van die Internet en sy wettigheid onder bestaande Suid-Afrikaanse outeursregwetgewing ondersoek word. In die ondersoek word gepoog om vas te stelof Suid-Afrikaanse outeursregwetgewing geskik is om die Internetprobieme wat tans bestaan te hanteer en of dit lei tot aanvaarbare resultate. Die eerste hoofstuk van die verhandeling sal In oorsig gee van die basiese beginsels van die Internet, insluitende die geskiedenis, ontwikkeling en funksie van die Internet. Verder sal die veranderende aspekte as gevolg van digitale tegnologie bespreek word. Die wêreldkarakter van die Internet gee aanleiding tot "internasionale" inbreukmakings en om hierdie rede oorweeg regerings die moontlikheid van internasionale ooreenkomste oor die beskerming van intellektuele eiendom in die digitale era. In hoofstuk twee word die bestaande internasionale harmonisering van outeursreg bespreek. Veral die vinnige aanname van die World Intellectual Property Organisation se verdrae in Desember 1996, illustreer dat daar In internasionale bewustheid is dat iets in die verband gedoen moet word. In die derde hoofstuk word die aanwending van die Suid-Afrikaanse outeursreg met betrekking tot die Internet bespreek. Eerstens word ondersoek of a digitale werk op die Internet op dieselfde wyse as 'n "tradisionele" werk beskerm kan word. Tweedens word die verskillende regte van die outeursreghebbende in verband met die gebruik van 'n werk op die Internet, bespreek. Derdens word die potensiële aanwending van die eksklusiewe regte van die outeursreghebbende op verskillende aksies op die Internet, soos byvoorbeeld kasberging, web koppeling en die werking van 'n gekoppelde diens, bespreek. Die Internet is 'n wêreldwye verskynsel en sodanig is outeursreginbreukmaking op hierdie stelsel 'n internasionale probleem. Die scenario van 'n wêreldwye, gelyktydige uitbuiting van werke op die Internet is in skerp konflik met die huidige stelsel van internasionale outeursregbeskerming wat stewig gegrond is op nasionale wetgewing met territoriale werking. Hoofstuk vier bied daarom 'n oorsig oor die toepaslike reg op 'n internasionale netwerk en analiseer die nodigheid en ook grense van beskerming.

Résumé :

The aim of this thesis is to apply Identity by Descent (IBD) methodology to identify ancestry connections among individuals from genetically similar populations. Recombination events diminish the likelihood to detect IBDs. As most of the aDNA samples date from 2,000 years ago or more, this methodology has rarely been applied to these studies. In this thesis we detect IBD among modern individuals from similar Bantu populations and among modern Europeans with an historical individual (700 years ago) from the Iberian peninsula, which was sequenced to a high coverage. Our results show that IBDs can be used to detect the genomic structure in genetically close populations. For example, they can be used to show high degrees of endogamy caused by isolation or to identify ancestral connections among individuals belonging to different populations that otherwise would be difficult to see with other more commonly used methods.

Résumé :

This thesis studies the formation of the early modern colonial state in Asia. Through an exploration of the English East India Company, it examines the dynamics which shaped political authority, colonial governance and the performance of state power in the seventeenth and eighteenth centuries. Specifically, the following research argues that a process of political decentralisation took place within the Company. This was driven by the pursuit of ‘private interests’ on behalf of the Company’s servants in Asia, who, as a result neglected, resisted or subverted the ‘public interests’ of their masters in London. Key to this reconfiguration of power were the family networks established by Company servants between Europe and Asia, and across Asia itself in this period. As constructs of exchange, circulation and movement, family networks allowed Company servants to exercise considerable political agency, distinct from metropolitan authorities. In so doing, they transformed the political landscape around them, laying the foundations of the early modern colonial state through a process of private state formation from the turn of the eighteenth century onwards.

Résumé :

This thesis explores oral communication in St. Gallen through the lens of the linen merchant Johannes Rütiner (1501-1556/7). By reconstructing Rütiner's network of informants and probing four genres of communication within their respective social contexts - jokes, gossip, rumour, and memory narratives -, it explores early modern sociability, the circulation of information, and the relationship between oral testimony, manuscript, and print. Sixteenth-century St. Gallers relied heavily on informal, oral networks to provide them with news and information of all kinds. An individual's access to information was thus to a large degree determined by the social networks within which they spent their life. As St. Gallers sought to secure a place for themselves in such circles, they in turn used jokes, gossip, and information of all kinds as a form of "communicative social capital", allowing them to present themselves as witty, well-connected, and knowledgeable. Rather than treating the instability of oral narratives as evidence of the inherent unreliability of the spoken word, this study proposes to analyse their evolution as a key to early modern mentalities. It also calls into question some of the dominant narratives regarding the printing revolution. Not only did oral communication continue to play a central role in the dissemination of information in the first half of the sixteenth century, but existing systems of "source criticism", developed in the context of dominantly oral networks, moreover cast doubt on the reliability of anonymous prints: because they made their trust in a piece of news conditional on their trust in the messenger, Rütiner and his fellow citizens often preferred oral narratives provided by familiar, trustworthy informants.

Résumé :

This thesis explores UK Internet users’ experiences of creating and maintaining friendships on social networking sites and online communities, with a particular focus on how online friendships compare to and affect participants’ face-to-face social networks. There is a large body of literature regarding online friendship and the use of online social networks. However, significantly less research has been published which focuses on UK-based users or on ‘online-to-offline’ friendships: relationships which begin online and move offline, becoming incorporated into participants’ everyday social circles. This study contributes to the literature in these under-researched areas. The study used a mixed-methods research design: an online questionnaire provided data which facilitated the purposeful selection of participants for face-to-face interviews. Although both quantitative and qualitative methods were used for data collection and analysis, the emphasis of the research is qualitative. Much of the current research into online interaction and friendship has been limited by the use of quantitative methods (Amichai-Hamburger, Kingsbury & Schneider, 2013). The qualitative focus of this research resulted in rich and deep data about participants’ experiences of online friendship. The results show that a significant majority of participants had made new friends on the Internet, and that online communities such as LiveJournal are more likely to foster new friendships than social networking sites such as Facebook. It was clear that online friendships are evaluated and measured in the same way as ‘traditional’ friendships. The migration of online friends into offline, everyday social circles was widely reported, suggesting that it is a frequent occurrence among the wider user population. Additionally, the migration of offline friends into online social networks was described by a number of participants, illustrating the use of online social networks to maintain and sustain offline, everyday friendships.

Résumé :

The research is a study of the context of the life and work of John Hooper, Bishop of Gloucester and Worcester, 1551-1555. It charts the nature of his relationships with friends, patrons, mentors, colleagues, and lay and clerical supporters and opponents in England and on the Continent, through the study of ecclesiastical, political, business and economic, intellectual, official and judicial, kinship and social networks in which he was involved. Its purpose is to reveal the complex mix of societal and confessional pressures influencing Hooper's approach and constraining his freedom of manoeuvre, and to a large extent determining how successful he was at achieving change. The study reveals key determinants of the nature and direction of the Reformation in England. It shows that the pressure to change doctrinal allegiances and to accommodate reformed church practices challenged not only personal confessional loyalties but also the very framework of society; that is, familial and social ties, economic, business and judicial groupings, educational affiliations, and ruling oligarchies. Within these societal networks there existed the momentum for, and resistance to, religious change. Confessional allegiances were just part of a complex mix of political and social pressures that included the exercise of patronage and protection, the use of conflict and compromise, the practise of different obligations, allegiances and loyalties, the employment of status and kinship, and the accommodation of various alliances and means of association. All of these influenced Hooper's approach and scope for action. As such, the research provides insight into why and how, in the development of the newly-reformed church in England, thoroughgoing religious change was resisted and contained.

Texte intégral

Résumé :

This dissertation examines the hitherto neglected role foreign, and specifically German, bankers played in the Chinese economy and the history of modern economic globalisation in China during the late 19th and early 20th centuries. By following the history of the German Deutsch-Asiatische Bank (DAB) during the last two decades of the Qing dynasty and the first years of the Chinese republic, this dissertation shows how the interaction between foreign bankers and Chinese officials, bankers and entrepreneurs led to the rapid internationalisation of Chinese finance, both in terms of public finance and the banking sector of China’s treaty port economy. Unlike most previous literature, which only depicts foreign banks in modern China as mere manifestations of foreign imperialism, this dissertation demonstrates that foreign banks acted as intermediary institutions that financially connected China to the first global economy and provided the financial infrastructure necessary to make modern economic globalisation in China during the late 19th and early 20th centuries possible. At the same time, this dissertation stresses the importance of Chinese agency for the operation of foreign banks in China’s treaty ports and shows that the interaction between foreign bankers and Chinese actors was made up as much of cooperation as of conflict. In sum, this dissertation not only furthers our knowledge of the role foreign banks played in the modern Chinese economy, but also contributes to our understanding of how China was financially integrated into the first global economy.

Résumé :

This thesis examines the networks involved in the production of the wardrobe of Robert Dudley, Earl of Leicester (1532/3-1588). It is clearly demonstrated that Leicester’s dress placed him alongside his contemporaries within the nobility. A successful and well functioning wardrobe network was crucial to achieving the required standard of dress. Establishing the identity of the individual members of the network enables the further examination of each person’s role within the network, and in dressing Leicester. Comprised of English masters embedded in their livery company politics and punctuated with foreign masters, the network provides an insight into business practice and social interaction in sixteenth century London.

Thesis (MScEng)--Stellenbosch University, 2013.
ENGLISH ABSTRACT: A secure product entitlement system allows one party, such as a pay-TV operator, to broadcast the same collection of information to several receiving parties while only allowing a certain subset of the receiving parties to access the information. This system must still be secure in the scenario where all receiving parties who are not allowed access to the information, pool their resources in an attempt to gain access to the information. Such a product entitlement system must also be bandwidth e cient since it can be deployed in networks where bandwidth is at a premium. The foundations of modern encryption techniques is reviewed and a survey of existing techniques, used to secure content in broadcast environments, is studied. From this collection of techniques two were identi ed as bandwidth e cient and are discussed in more detail before being implemented. An attempt is then made to design a new secure bandwidth e cient encryption scheme for protecting content in a broadcast environment. Several iterations of the design is detailed, including the security aw which makes each design insecure. The nal design was implemented and compared in several metrics to the two previously selected bandwidth e cient schemes. A framework to test the correctness of the schemes over a network is also designed and implemented. Possible future avenues of research are identi ed with regards to creating a secure broadcast encryption scheme and improving the software solution in which to use such a scheme.

Hierdie stelsel moet steeds die inligting beskerm in die geval waar al die ontvangende partye wat toegang geweier word, hul hulpbronne saamsmee in 'n poging om toegang te verkry. So 'n produk-aanspraak-stelsel moet ook bandwydte doeltre end benut, aangesien dit gebruik kan word in netwerke waar bandwydte baie duur is. Die fondamente van die moderne enkripsietegnieke word hersien. 'n Opname van bestaande tegnieke wat gebruik word om inligting te beskerm in 'n uitsaai omgewing word bestudeer. Uit hierdie versameling tegnieke word twee geïdenti seer as tegnieke wat bandwydte doeltre end benut en word meer volledig bespreek voordat dit geïmplementeer word. 'n Poging word dan aangewend om 'n nuwe veilige bandwydte doeltre ende enkripsietegniek te ontwerp vir die beskerming van inligting wat uitgesaai word. Verskeie iterasies van die ontwerp word uiteengesit, met 'n bespreking van die sekuriteitsfout wat elke ontwerp onveilig maak. Die nale ontwerp is geïmplementeer en aan die hand van verskeie maatstawwe vergelyk met die twee bandwydte doeltre ende tegnieke, wat voorheen gekies is. 'n Raamwerk om die korrektheid van die tegnieke oor 'n netwerk te toets, is ook ontwerp en geïmplementeer. Moontlike toekomstige rigtings van navorsing word geïdenti seer met betrekking tot die skep van 'n veilige uitsaai enkripsietegniek en die verbetering van die sagtewareoplossing wat so 'n tegniek gebruik.

Résumé :

This dissertation first studies two-dimensional wavelet codes (TDWCs). TDWCs are introduced as a solution to the problem of designing a 2-D code that has low decoding- complexity and has the maximum erasure-correcting property for rectangular burst erasures. The half-rate TDWCs of dimensions N₁ X N₂ satisfy the Reiger bound with equality for burst erasures of dimensions N₁ X N₂/2 and N₁/2 X N₂, where GCD(N₁,N₂) = 2. Examples of TDWC are provided that recover any rectangular burst erasure of area N₁N₂/2. These lattice-cyclic codes can recover burst erasures with a simple and efficient ML decoding. This work then studies the problem of distributed source coding for two and three correlated signals using channel codes. We propose to model the distributed source coding problem with a set of parallel channel that simplifies the distributed source coding to de- signing non-uniform channel codes. This design criterion improves the performance of the source coding considerably. LDPC codes are used for lossless and lossy distributed source coding, when the correlation parameter is known or unknown at the time of code design. We show that distributed source coding at the corner point using LDPC codes is simplified to non-uniform LDPC code and semi-random punctured LDPC codes for a system of two and three correlated sources, respectively. We also investigate distributed source coding at any arbitrary rate on the Slepian-Wolf rate region. This problem is simplified to designing a rate-compatible LDPC code that has unequal error protection property. This dissertation finally studies the distributed source coding problem for applications whose wireless channel is an erasure channel with unknown erasure probability. For these application, rateless codes are better candidates than LDPC codes. Non-uniform rateless codes and improved decoding algorithm are proposed for this purpose. We introduce a reliable, rate-optimal, and energy-efficient multicast algorithm that uses distributed source coding and rateless coding. The proposed multicast algorithm performs very close to network coding, while it has lower complexity and higher adaptability.

Campello, Daniel Jose. « Optimizing Main Memory Usage in Modern Computing Systems to Improve Overall System Performance ». FIU Digital Commons, 2016. http://digitalcommons.fiu.edu/etd/2568.

Texte intégral

Résumé :

Operating Systems use fast, CPU-addressable main memory to maintain an application’s temporary data as anonymous data and to cache copies of persistent data stored in slower block-based storage devices. However, the use of this faster memory comes at a high cost. Therefore, several techniques have been implemented to use main memory more efficiently in the literature. In this dissertation we introduce three distinct approaches to improve overall system performance by optimizing main memory usage. First, DRAM and host-side caching of file system data are used for speeding up virtual machine performance in today’s virtualized data centers. The clustering of VM images that share identical pages, coupled with data deduplication, has the potential to optimize main memory usage, since it provides more opportunity for sharing resources across processes and across different VMs. In our first approach, we study the use of content and semantic similarity metrics and a new algorithm to cluster VM images and place them in hosts where through deduplication we improve main memory usage. Second, while careful VM placement can improve memory usage by eliminating duplicate data, caches in current systems employ complex machinery to manage the cached data. Writing data to a page not present in the file system page cache causes the operating system to synchronously fetch the page into memory, blocking the writing process. In this thesis, we address this limitation with a new approach to managing page writes involving buffering the written data elsewhere in memory and unblocking the writing process immediately. This buffering allows the system to service file writes faster and with less memory resources. In our last approach, we investigate the use of emerging byte-addressable persistent memory technology to extend main memory as a less costly alternative to exclusively using expensive DRAM. We motivate and build a tiered memory system wherein persistent memory and DRAM co-exist and provide improved application performance at lower cost and power consumption with the goal of placing the right data in the right memory tier at the right time. The proposed approach seamlessly performs page migration across memory tiers as access patterns change and/or to handle tier memory pressure.
