▼ Research has identified that websites can gain an added advantage by getting listed in Search Engine results Pages (SERPs) during search sessions by searchers as SERPS refer targeted traffic to the websites. Search Engine Optimization (SEO) enables websites to become visible in search engines during search sessions for featured products or services. SEO is a complex technique which is directly affected by the ranking algorithms of search engines such as Google. Bearing in mind that Google employs in excess of 200 dynamic ranking factors in its algorithm it can be seen that optimization is not straightforward. Given this complex environment, websites find it difficult to initiate and implement SEO. SEO knowledge and experience gained from optimizing websites in the past is highly valuable and applicable to optimize websites both now and in the future. Therefore the main aim of the research in this thesis is to investigate the problem of optimization of websites using the prior experience gained through the optimization of several case study websites. To facilitate this, novel process models have been designed in order to capture the experience of implementing essential techniques of SEO and to explain the procedure of implementation of fundamental on-page SEO techniques that have been shown previously to yield results (i.e. increases in ranking) for past case study websites. Quantitative experiments and qualitative evaluation were undertaken to verify the efficacy of the novel process models through their application to case study websites. Mixed methods were used in order to answer the research questions, inductive experimental methods to produce, finesse and test the process models and qualitative enquiry through means of a focus group to gather peer review from professionals within the field who had previously been trained and conducted a trial using the process models. Implementation procedures of acknowledged essential on-page SEO techniques were identified from past case study websites, which have been represented in the novel process models designed in the current research and empirically investigated by applying them in the experimental case study websites. These models were applied through quantitative experiments that identified essential on-page SEO techniques which were then implemented in two experimental case study websites as per the procedures represented in the process models. These experiments have yielded positive results, resulting in establishing and/or enhancing the visibility of case study websites in SERPs. Further the implementation procedures of essential on-page SEO techniques were represented in the designed process models and stored in an SEO experience base on the principle of INRECA-II methodology. Results of the focus group suggest that the process models do achieve credible results (i.e. establishing and/or enhancing visibility of websites in SERPs) through their application and are suitable for use by both novices and professionals alike. Overall the results achieved from both the…

▼ The outsourcing of data storage and related infrastructure to third-party services in the cloud is a trend that has gained considerable momentum in the last decade due to the savings it affords companies in both capital and operational costs. Although encryption can alleviate some of the privacy concerns associated with cloud storage, it comes at the cost of decreased utility of data once it is in the cloud. For instance, cloud services for searching over a large set of files are useless when those files are encrypted using standard, randomized techniques. Moreover, even though the files are encrypted, the historical access pattern over a data set (e.g., file access times/frequency, memory read/write locations) can leak significant information to malicious parties that can be combined with other metadata to partially reveal the file contents. Two research thrusts that address these issues are Symmetric Searchable Encryption (SSE) and Oblivious RAM (ORAM). SSE schemes provide an efficient means for searching over encrypted data that is stored on an untrusted server. These schemes, however, are inherently susceptible to statistical attacks by observing the history of de- terministically encrypted search queries, along with the access pattern resulting from those queries. ORAM, by design, can prevents such leakages, but it introduces high communication overhead, among other challenges. In this work we introduce new ORAM schemes tailored for more efficient private access to tree data structures, which are commonly used as search indexes. We make multi-faceted contributions that include: (i) a formal definition for obliviousness in the relaxed setting where the external storage provider knows we are accessing a tree data structure, (ii) a formal proof showing that our schemes satisfy this definition, with an- alytical and empirical results showing that we reduce transmission overhead by several factors over state-of-the-art ORAM schemes, and (iii) a Python software package called PyORAM (Python-based Oblivious RAM) that provides researchers with a powerful set of tools to build upon current ORAM methods tailored for the cloud storage set- ting. Our work has broad impacts for searchable encryption via private database search with reduced transmission requirements, which is vital for privacy-critical applications in governmental and healthcare systems.

▼ Information is useless unless it is used whilst still applicable. Having a system that notifies the user of important messages using the most appropriate medium and device will benefit users that rely on time critical information. There are several existing systems and models for mobile notification as well as for adaptive mobile notification using context awareness. Current models and systems are typically designed for a specific set of mobile devices, modes and services. Communication however, can take place in many different modes, across many different devices and may originate from many different sources. The aim of this research was to develop a model for adaptive mobile notification using context awareness. An extensive literature study was performed into existing models for adaptive mobile notification systems using context awareness. The literature study identified several potential models but no way to evaluate and compare the models. A set of requirements to evaluate these models was developed and the models were evaluated against these criteria. The model satisfying the most requirements was adapted so as to satisfy the remaining criteria. The proposed model is extensible in terms of the modes, devices and notification sources supported. The proposed model determines the importance of a message, the appropriate device and mode (or modes) of communication based on the user‘s context, and alerts the user of the message using these modes. A prototype was developed as a proof-of-concept of the proposed model and evaluated by conducting an extensive field study. The field study highlighted the fact that most users did not choose the most suitable mode for the context during their initial subscription to the service. The field study also showed that more research needs to be done on an appropriate filtering mechanism for notifications. Users found that the notifications became intrusive and less useful the longer they used them Advisors/Committee Members: Wesson, J L Prof.

▼ Mobile devices have become ubiquitous and provide ever richer content and functionality. At the same time, applications are also becoming more complex and require ever increasing amount of computational power and energy. With cloud computing providing unlimited elastic on-demand resources, supporting mobile devices with cloud allows overcoming limitations of mobile devices. This is generally known as Mobile Cloud Computing (MCC) and can be achieved through code offloading that selects computationally or data intensive parts of an application, outsources them to more-resourceful spaces and brings back the final results. While code offloading has been widely studied in the past within the context of distributed systems and grid computing, applying it to current mobile applications requires significant amount of manual changes to existing application codes. An alternative is to outsource the entire application process or the whole virtual machine in which the application is running. This solution assumes running the same code on a more-resourceful system is more efficient, but it is coarse-grained and requires significant amount of data to be transferred. Furthermore, requirements and expectations from mobile applications vary considerably by different users using wide range of mobile devices in various environmental conditions. This diversity in requirements and expectations creates wide range of target offloading goals, ranging from maximizing application performance to minimizing mobile energy consumption. The increased dynamicity and complexity of mobile cloud applications requires open systems that interact with the environment while addressing application-specific constraints, user expectations and hardware limitations. Our goal is to facilitate mobile cloud application development by masking all the complexity of mobile-to-cloud code offloading without requiring application developers to rewrite their code or perform additional manual work. Our focus is on separating the application logic, to be developed by programmers, from the application component configuration and distribution, to be adjusted transparently and dynamically at run-time. Our framework is fine-grained, supporting mobile application configuration and distribution at the granularity of individual components; it is flexible, allowing organizations, application developers, or end-users easily adjust target offloading goal or define policy-driven restrictions on offloading budget, execution quality, or privacy and move around of components without modifying the existing application codes; and it is adaptive, addressing the dynamicity in run-time conditions and end-user contexts. It further supports component distribution in a hybrid cloud environment consisting of multiple public and private cloud spaces. Finally, it provides a new code offloading model that supports fully parallel program execution, where application components located at mobile device and multiple cloud spaces are executed independently but concurrently. The proposed… Advisors/Committee Members: Agha, Gul (advisor), Agha, Gul (Committee Chair), Abdelzaher, Tarek F. (committee member), Vaidya, Nitin (committee member), Varela, Carlos A.

▼ These days, research groups such as Google, Microsoft, and Rigetti are working towards fabricating quantum devices which have hundreds to thousands of qubits. In recently proposed quantum algorithms, i.e. hybrid quantum-classical algorithms, such quantum devices are used as subroutines for calculation of classically intractable tasks. However, the applicability of hybrid algorithms was quite limited, for example, the search of the ground state, and simulation of the dynamics of quan- tum systems. In addition, near-term quantum devices are expected to be quite noisy, impairing the precision of computation seriously and removing any potential advantages with quantum computers. Therefore, it is necessary to extend the applicability of hybrid algorithms and mitigate errors on quantum computers. In this thesis, we describe the generalisation of hybrid algorithms so that they can be applied to variety of problems, such as search of the spectrum of quantum systems, simulation of open quantum systems and even general mathematical tasks. The algorithm for finding spectra is useful for applications such as new drug discovery, design of batteries. Generally speaking, quantum systems of interest to physicists, chemists, and materials scientists inevitably interact with their environments, and quantum states are decohered. Therefore, to investigate quantum phenomena, new algorithms simulating open quantum systems are described in this thesis. Algorithms for general mathematical tasks such as matrix multiplication to a vector and solving linear equations, useful for a large number of problems, such as machine learning, are also presented. Furthermore, in order to make hybrid algorithms useful, we also invented a practical error mitigation method for suppressing physical errors, which may make hybrid algorithms useful. We showed that errors can be suppressed for a quantum system with over 50 qubits for the current achievable error rate, which is believed to be hard to simulate with classical computers. Also, we generalised the error mitigation technique to be applied to mitigate algorithmic errors, which may enhance the accuracy of Hamiltonian simulation.

▼ Mobile computing is rapidly becoming part of healthcare’s electronic landscape, helping to provide better quality of care and reduced cost. While the technology provides numerous advantages to the healthcare industry, it is not without risk. The size and portable nature of mobile computing devices present a highly vulnerable environment, which threaten the privacy and security of health information. Since these devices continually access possibly sensitive healthcare information, it is imperative that these devices are considered for security in order to meet regulatory compliance. In fact, the increase in government and industry regulation to ensure the privacy and security of health information, makes mobile security no longer just desirable, but mandatory. In addition, as healthcare becomes more aware of the need to reinforce patient confidence to gain competitive advantage, it makes mobile security desirable. Several guidelines regarding security best practices exist. Healthcare institutions are thus faced with matching the guidelines offered by best practices, with the legal and regulatory requirements. While this is a valuable question in general, this research focuses on the aspect of considering this question when considering the introduction of mobile computing into the healthcare environment. As a result, this research proposes a framework that will aid IT administrators in healthcare to ensure that privacy and security of health information is extended to mobile devices. The research uses a comparison between the best practices in ISO 17799:2005 and the regulatory requirements stipulated in HIPAA to provide a baseline for the mobile computing security model. The comparison ensures that the model meets healthcare specific industry requirement and international information security standard. In addition, the framework engages the Information Security Management System (ISMS) model based on the ISO 27000 standard. The framework, furthermore, points to existing technical security measurers associated with mobile computing. It is believed that the framework can assist in achieving mobile computing security that is compliant with the requirements in the healthcare industry Advisors/Committee Members: Botha, Reinhardt A Prof.

▼ Realization of the conventional Von Neumann architecture faces increasing challenges due to growing process variations, device reliability and power consumption. As an appealing architectural solution, brain-inspired neuromorphic computing has drawn a great deal of research interest due to its potential improved scalability and power efficiency, and better suitability in processing complex tasks. Moreover, inherit error resilience in neuromorphic computing allows remarkable power and energy savings by exploiting approximate computing. This dissertation focuses on a scalable and energy efficient neurocomputing architecture which leverages emerging memristor nanodevices and a novel approximate arithmetic for cognitive computing. First, brain-inspired digital neuromorphic processor (DNP) architecture with memristive synaptic crossbar is presented for large scale spiking neural networks. We leverage memristor nanodevices to build an N ??N crossbar array to store not only multibit synaptic weight values but also the network configuration data with significantly reduced area cost. Additionally, the crossbar array is accessible both column- and row-wise to significantly expedite the synaptic weight update process for on-chip learning. The proposed digital pulse width modulator (PWM) readily creates a binary pulse with various durations to read and write the multilevel memristors with low cost. Our design integrates N digital leaky integrate-and-fire (LIF) silicon neurons to mimic their biological counterparts and the respective on-chip learning circuits for implementing spike timing dependent plasticity (STDP) learning rules. The proposed column based analog-to-digital conversion (ADC) scheme accumulates the pre-synaptic weights of a neuron efficiently and reduces silicon area by using only one shared arithmetic unit for processing LIF operations of all N neurons. With 256 silicon neurons, the learning circuits and 64K synapses, the power dissipation and area of our design are evaluated as 6.45 mW and 1.86 mm2, respectively, in a 90 nm CMOS technology. Furthermore, arithmetic computations contribute significantly to the overall processing time and power of the proposed architecture. In particular, addition and comparison operations represent 88.5% and 42.9% of processing time and power for digital LIF computation, respectively. Hence, by exploiting the built-in resilience of the presented neuromorphic architecture, we propose novel approximate adder and comparator designs to significantly reduce energy consumption with a very low er- ror rate. The significantly improved error rate and critical path delay stem from a novel carry prediction technique that leverages the information from less significant input bits in a parallel manner. An error magnitude reduction scheme is proposed to further reduce amount of error once detected with low cost in the proposed adder design. Implemented in a commercial 90 nm CMOS process, it is shown that the proposed adder is up to 2.4?? faster and 43% more energy efficient over… Advisors/Committee Members: Li, Peng (advisor).

▼ A distributed system is a collection of computing entities that communicate with each other to solve some problem. Distributed systems impact almost every aspect of daily life (e.g., cellular networks and the Internet); however, it is hard to develop services on top of distributed systems due to the unreliable nature of computing entities and communication. As handheld devices with wireless communication capabilities become increasingly popular, the task of providing services becomes even more challenging since dynamics, such as mobility, may cause the network topology to change frequently. One way to ease this task is to develop collections of information infrastructures which can serve as building blocks to design more complicated services and can be analyzed independently. The first part of the dissertation considers the dining philosophers problem (a generalization of the mutual exclusion problem) in static networks. A solution to the dining philosophers problem can be utilized when there is a need to prevent multiple nodes from accessing some shared resource simultaneously. We present two algorithms that solve the dining philosophers problem. The first algorithm considers an asynchronous message-passing model while the second one considers an asynchronous shared-memory model. Both algorithms are crash fault-tolerant in the sense that a node crash only affects its local neighborhood in the network. We utilize failure detectors (system services that provide some information about crash failures in the system) to achieve such crash fault-tolerance. In addition to crash fault-tolerance, the first algorithm provides fairness in accessing shared resources and the second algorithm tolerates transient failures (unexpected corruptions to the system state). Considering the message-passing model, we also provide a reduction such that given a crash fault-tolerant solution to our dining philosophers problem, we implement the failure detector that we have utilized to solve our dining philosophers problem. This reduction serves as the first step towards identifying the minimum information regarding crash failures that is required to solve the dining philosophers problem at hand. In the second part of this dissertation, we present information infrastructures for mobile ad hoc networks. In particular, we present solutions to the following problems in mobile ad hoc environments: (1) maintaining neighbor knowledge, (2) neighbor detection, and (3) leader election. The solutions to (1) and (3) consider a system with perfectly synchronized clocks while the solution to (2) considers a system with bounded clock drift. Services such as neighbor detection and maintaining neighbor knowledge can serve as a building block for applications that require point-to-point communication. A solution to the leader election problem can be used whenever there is a need for a unique coordinator in the system to perform a special task.

▼ Recent research has proposed a variety of cross-cutting tools to help monitor and troubleshoot end-to-end behaviors in distributed systems. However, most prior tools focus on data collection and aggregation, and treat analysis as a distinct step to be performed later, offline. This restricts the applicability of such tools to only doing post-facto analysis. However, this is not a fundamental limitation. Recent research has proposed tools that integrate analysis and decision-making at runtime, to directly enforce end-to-end behaviors and adapt to events. In this thesis I present two new applications of cross-cutting tools to previously unexplored domains: resource management, and dynamic monitoring. Retro, a cross-cutting tool for resource management, provides end-to-end performance guarantees by propagating tenant identifiers with executions, and using them to attribute resource consumption and enforce throttling decisions. Pivot Tracing, a cross-cutting tool for dynamic monitoring, dynamically monitors metrics and contextualizes them based on properties deriving from arbitrary points in an end-to-end execution. Retro and Pivot Tracing illustrate the potential breadth of cross-cutting tools in providing visibility and control over distributed system behaviors. From this, I identify and characterize the common challenges associated with developing and deploying cross-cutting tools. This motivates the design of baggage contexts, a general-purpose context that can be shared and reused by different cross-cutting tools. Baggage contexts abstract and encapsulate components that are otherwise duplicated by most cross-cutting tools, and decouples the design of tools into separate layers that can be addressed independently by different teams of developers. The potential impact of a common architecture for cross-cutting tools is significant. It would enable more pervasive, more useful, and more diverse cross-cutting tools, and make it easier for developers to defer development-time decisions about which tools to deploy and support.

▼ Hardware accelerators and custom computing platforms are being widely used in high-throughput computation domains. With the wide usage, there is also an increasing need to operate these hardware accelerators in resource-constrained environments. In this dissertation work, we address two different ways of exploring possibilities for producing low-area and low-power hardware accelerators. First, we propose an analytical modeling of design metrics such as area, power, and throughput for hardware accelerators. Accelerators have various tunable implementation parameters, both at the algorithm and hardware levels. Physically synthesizing every possible design permutation to discover optimum implementations is highly inefficient given the exponentially large search space. We propose sampling a small fraction of the design space and using these samples to train analytical models that will accurately predict area, power, throughput for other unexplored parameter combinations. By doing this analytically, we take away a bulk of the time-consuming synthesis process. We also use these mathematical models to accurately formulate various multi-objective optimization trade-offs between area, power, and output accuracy. For the second part of this dissertation, we pursue an idea we learned from the first part — that computational accuracy of circuit implementations within certain application domains can be traded-off to make accelerators consume less area and power. We introduce a novel idea for automated synthesis of approximate circuits directly from their behavioral descriptions. By applying transformations that introduce a controlled amount of error, we make a number of approximate variants of the original circuits. We also realize a streamlined design space exploration process so that the creation of newer approximate variants does not cause an exponential increase in the design space. Finally, we study various techniques to expand the search scope for better approximate designs and achieve significantly better power savings without additional loss in output accuracy. We also propose a first-of-its-kind methodology to perform targeted approximations on timing-critical paths of a custom circuit hardware accelerator so as to reduce its delay. We use this delay reduction to use standard voltage scaling and make additional savings on power consumption.

▼ Innovations are necessary to ride the inevitable tide of change. Most of organizations are striving to reduce their computing cost through the means of virtualization. This demand of reducing the computing cost has led to the innovation of Cloud Computing. Cloud Computing offers better computing through improved utilization and reduced administration and infrastructure costs. Cloud Computing is the sum of Software as a Service (SaaS), Infrastructure as a Service (IaaS) and Platform as a service (PaaS). In a nutshell, it’s a computing model based on utility Computing. Cloud Computing is still at its infant stage and a relatively new technology for the organizations especially the non-governmental organizations in Kenya. Therefore, most of the organizations are not very confident and ready to adopt it. This research paper tackles this issue for organizations in terms of adoptability of the technology especially the NGO sector in Kenya. In this paper the researcher discusses the perceived benefits, awareness levels, drivers of adoption as well as barriers to cloud computing adoption and assess the extent to which this technology has been adopted in the international NGOs in Kenya. This study revealed the awareness levels to be overwhelming and further validated that economical, technical, strategic and functional being the key drivers of adoption. Lack of clear strategy, lack of ownership and loss of confidentiality were also endorsed as key barriers to adoption. Majority of the NGOs had more than 71% computerization levels with a paltry 26% of this having adopted the cloud. Cloud providers key concerns according to the study include security, the perceived loss of ownership and fear of confidentiality breach so us to encourage organizations to take up more of the cloud services on offer. Organizations should also be deliberate to capture cloud computing in their strategies to motivate adoption. The intention of this research is to provide information about cloud computing that will assist those interested non-governmental organizations (NGOs) in this technology in making well-informed decisions. NGOs must become aware of the predictors that if adequately examined will indicate successful adoption of cloud computing for NGOs in Kenya.

▼ Cloud computing is a very popular field at present which is growing very fast and the future of the field seems really wide. With progressive spotlight on cloud computing as a possible solution for a flexible, on-demand computing infrastructure for lots of applications, many companies and unions have started using it. Obviously, cloud computing has been recognized as a model for supporting infrastructure, platform and software services. Within cloud systems, massive distributed data center infrastructure, virtualized physical resources, virtualized middleware platform such as VMware as well as applications are all being provided and consumed as services. The cloud clients should get good and reliable services from a provider and the provider should allocate the resources in a proper way so as to render good services to a client. This brings about the problem of optimization where clients request for more services than they actually require leading to wastage of the cloud storage resource .This demands for optimization both on the part of the client and the cloud service provider. This has lead to increased research in the various techniques that can be used for resource allocation within cloud services. This research focuses on the analysis of machine learning as a technique that can be used to predict the cloud storage service request patterns from the clients. The research focuses on a review of machine learning as a technique that can be used to predict and therefore optimize the user storage resource demand and usage for the case of cloud computing storage IaaS. Data on cloud storage resource usage was subjected to experiments using machine learning techniques so as to determine which give the most accurate prediction. Some of these machine learning techniques to be reviewed in this research include linear regression, artificial neural networks (ANN), support vector machines (SVM).From the experiments done in this research, it can be concluded that the use of support vector machine algorithm (SVM) proves to be the best algorithm for learning the storage resource usage patterns and predicting their future usage so as to enable better resource budgeting.

Falar de mudanças na área da informática é como falar de frio no Pólo Norte, ou seja, não estamos perante nada de novo. Existem contudo alterações que representam uma descontinuidade com o passado, e esse tipo de alterações são já bem menos frequentes. O Cloud Computing insere-se nesta lista bastante mais restrita. Estamos a falar de um novo paradigma da computação que começou a dar os primeiros passos entre o final do século passado e o início deste, aquando da disponibilização dos primeiros serviços online (nomeadamente o Gmail, Hotmail, Salesforce CRM, entre outros) e que, neste momento, impulsionado pela actual conjuntura económica e por fenómenos associados à deslocalização da força de trabalho, despertou o interesse do meio empresarial. A este nível, o cloud computing representa uma alteração radical relativamente à estruturação das TI e à forma como estas passam a suportar os sistemas de informação das organizações, e também à forma como as organizações pensam os seus investimentos em TI. É importante compreender que essas alterações não se confinam apenas à esfera tecnológica. Na verdade, elas são bem mais abrangentes na medida em que podem provocar alterações ao próprio modelo de negócio das organizações. Este é aliás um dos aspectos a reter, devemos olhar para o Cloud Computing mais como um modelo de negócio que faz uso de um conjunto de tecnologias existentes, do que propriamente uma nova tecnologia. Esta dissertação tem como objectivo realizar uma análise detalhada acerca do Cloud Computing apresentando o conceito, as camadas, os modelos, as plataformas existentes e respectivos fornecedores. Para além desses aspectos, pretende-se analisar a situação do Cloud Computing em Portugal, avaliando o seu grau de maturidade. Como componente prática desta dissertação, será realizada a migração de uma aplicação Web para o formato cloud, utilizando para o efeito a plataforma da Microsoft, Windows Azure. Essa migração será realizada com o intuito de identificar eventuais dificuldades ocorridas nesse processo. Adicionalmente será realizada uma análise de performance face a um modelo de alojamento tradicional.

Speaking of change in computing is like talking of cold at the North Pole, that is, we are not faced with anything new. However, there are changes that represent a discontinuity with the past, and such changes are far less frequent. Cloud Computing is part of this much more restricted list. We are talking about a new computing paradigm that began to take its first steps towards the end of the last century and the beginning of this one, when the first services became available online (namely Gmail, Hotmail, Salesforce CRM, among others) and which at the moment, driven by current economic phase with the phenomena associated with the relocation of the workforce, awakened the interest of the business world. At this level, Cloud Computing represents a radical change on…

▼ Cloud computing technology has been emerging and spreading at a great pace due to its service oriented architecture, elasticity, cost-effectiveness, etc. Many organizations are using Infrastructure-as-a-Service (IaaS) public Clouds for data migration away from traditional IT Infrastructure but there are a few fields such as finance, hospitals, military and others that are reluctant to use public Clouds due to perceived security vulnerability. Enterprises in such fields feel more vulnerable to security breaches and feel secure using in-house IT infrastructure. The introduction of private Clouds is a solution for these businesses. Private Clouds have been substituted for the traditional IT Infrastructure due to its flexible ``pay-as-you-go" model within an organization by departments and enhanced privacy relative to public Clouds in the form of administration control and supervision. Goal of my thesis is to build and evaluate a private Cloud that can provide virtual machines (VMs) as a service and applications as a service. To achieve this goal, in my thesis, I have built and evaluated a service oriented IaaS model of private Cloud. I have used off-the-shelf servers and open-source software for this purpose. I have proposed a new replication strategy using an Openstack component called Cinder. My experiments show that efficient VM failure recovery on the basis of ``preparation delay" time can be achieved using my strategy. I have studied a real-world application of option pricing from the finance market and have used that application for the purpose of testing my private Cloud for compute workload and accuracy of the pricing results. Later, I have compared performance between Cloud VMs and standalone servers. The performance of Cloud VM is found to be better to standalone servers as long as the number of virtual CPUs (vCPUs) are limited to single node. Stratus clouds are groups of small clouds that collectively give a spectacular sight in the sky. The private Cloud I have built uses multiple small modules to achieve the stated goal and hence I named my private Cloud ``Stratus". This Stratus private Cloud is now ready for deploying applications, and for providing VMs on-demand. Advisors/Committee Members: Thulasiram, Ruppa K.

▼ The Web is rapidly becoming a mature platform to host distributed applications. Pervasive computing application running on the Web are now common in the era of the Web of Things, which has made it increasingly simple to integrate sensors and microcontrollers in our everyday life. Such devices are of great in- terest to Makers with basic Web development skills. With them, Makers are able to build small smart stream processing applications with sensors and actuators without spending a fortune and without knowing much about the technologies they use. Thanks to ongoing Web technology trends enabling real-time peer-to- peer communication between Web-enabled devices, Web browsers and server- side JavaScript runtimes, developers are able to implement pervasive Web ap- plications using a single programming language. These can take advantage of direct and continuous communication channels going beyond what was possible in the early stages of the Web to push data in real-time. Despite these recent advances, building stream processing applications on the Web of Things remains a challenging task. On the one hand, Web-enabled devices of different nature still have to communicate with different protocols. On the other hand, dealing with a dynamic, heterogeneous, and volatile environment like the Web requires developers to face issues like disconnections, unpredictable workload fluctuations, and device overload. To help developers deal with such issues, in this dissertation we present the Web Liquid Streams (WLS) framework, a novel streaming framework for JavaScript. Developers implement streaming operators written in JavaScript and may interactively and dynamically define a streaming topology. The framework takes care of deploying the user-defined operators on the available devices and connecting them using the appropriate data channel, removing the burden of dealing with different deployment environments from the developers. Changes in the semantic of the application and in its execution environment may be ap- plied at runtime without stopping the stream flow. Like a liquid adapts its shape to the one of its container, the Web Liquid Streams framework makes streaming topologies flow across multiple heterogeneous devices, enabling dynamic operator migration without disrupting the data flow. By constantly monitoring the execution of the topology with a hierarchical controller infrastructure, WLS takes care of parallelising the operator execution across multiple devices in case of bottlenecks and of recovering the execution of the streaming topology in case one or more devices disconnect, by restarting lost operators on other available devices.

▼ Caractériser et simuler les interactions entre les eaux de surface et souterraines s’avère être un enjeu de plus en plus important afin de garantir une eau de qualité pour des puits de pompage situés à proximité d’une rivière. Grâce à la dernière génération de modèles numériques physiques intégrant les écoulements de surface et souterrains, il est maintenant possible de simuler tous les processus physiques gouvernant ces interactions. Cependant, les résultats de ces modèles sont souvent peu satisfaisants. Plusieurs études suggèrent que l’utilisation des charges hydrauliques et des débits de la rivière n’est pas suffisante pour décrire et contraindre ces processus complexes. Une revue bibliographique de ces différentes études est présentée dans le chapitre 2. Afin de parvenir à un meilleur calage de ces modèles, l’utilisation d’autres types d’observations que l’on peut qualifier de non-conventionnelles doit être envisagée. Ces observations non-conventionnelles peuvent être par exemple les flux caractérisant les interactions ou la concentration de solutés. Le but principal de cette thèse de doctorat est de montrer que l’utilisation de ces observations non conventionnelles permet non seulement d’améliorer significativement le calage de ces modèles, mais également de réduire grandement les incertitudes de leurs projections. Le chapitre 4 présente le développement d’une nouvelle méthode utilisant l’accroissement de cernes des arbres afin de quantifier l’historique de transpiration des arbres riverains. Les observations non-conventionnelles obtenues grâce à cette méthode ont ensuite été utilisées pour caler un modèle HydroGeoSphere couplant les écoulements souterrains et de surface ainsi que la transpiration des végétaux. Une analyse d’incertitude a permis de quantifier la réduction de l’incertitude induite par l’utilisation de ces observations non-conventionnelles. Le chapitre 5 présente l’utilisation de traceurs naturels afin de caler un modèle d’écoulements souterrains et de surface. Cette étude fut réalisée dans le cadre d’un essai de traçage réalisé dans un champ de captage situé en Suisse. Après avoir évalué le temps de résidence de l’eau en utilisant les concentrations en argon-37, une analyse du mélange entre les eaux récemment infiltrées et les eaux plus vieilles a été réalisée en analysant les températures d’infiltration des gaz rares. Ces deux informations qui permettent de décrire les interactions entre la rivière et l’aquifère furent utilisées en plus des observations conventionnelles pour caler et contraindre le modèle de ce champ de captage. Les résultats obtenus montrent clairement une amélioration des capacités prédictives du modèle ainsi qu’une diminution de ses incertitudes. Le chapitre 3 décrit une nouvelle méthode utilisant la méthode de Monte-Carlos afin d’identifier des zones non saturées entre le lit d’une rivière et d’un aquifère tous deux aux propriétés hétérogènes. Finalement, le chapitre6 présente une nouvelle approche de simulation utilisant HydroGeoSphere, le filtre de Kalman… Advisors/Committee Members: Philip (Dir.), Daniel (Codir.).

▼ In finite element simulations, the handling of geometrical objects and their discrete representation is a critical aspect in both serial and parallel scientific software environments. The development of codes targeting such envinronments is subject to great development effort and man-hours invested. In this thesis we approach these issues from three fronts. First, stable and efficient techniques for the transfer of discrete fields between non matching volume or surface meshes are an essential ingredient for the discretization and numerical solution of coupled multi-physics and multi-scale problems. In particular L2-projections allows for the transfer of discrete fields between unstructured meshes, both in the volume and on the surface. We present an algorithm for parallelizing the assembly of the L2-transfer operator for unstructured meshes which are arbitrarily distributed among different processes. The algorithm requires no a priori information on the geometrical relationship between the different meshes. Second, the geometric representation is often a limiting factor which imposes a trade-off between how accurately the shape is described, and what methods can be employed for solving a system of differential equations. Parametric finite-elements and bijective mappings between polygons or polyhedra allow us to flexibly construct finite element discretizations with arbitrary resolutions without sacrificing the accuracy of the shape description. Such flexibility allows employing state-of-the-art techniques, such as geometric multigrid methods, on meshes with almost any shape.t, the way numerical techniques are represented in software libraries and approached from a development perspective, affect both usability and maintainability of such libraries. Completely separating the intent of high-level routines from the actual implementation and technologies allows for portable and maintainable performance. We provide an overview on current trends in the development of scientific software and showcase our open-source library utopia. Advisors/Committee Members: Rolf (Dir.).

▼ Online hosed services are what is referred to as Cloud Computing. Access to these services is via the internet. h shifts the traditional IT resource ownership model to renting. Thus, high cost of infrastructure cannot limit the less privileged from experiencing the benefits that this new paradigm brings. Therefore, c loud computing provides flexible services to cloud user in the form o f software, platform and infrastructure as services. The goal behind cloud computing is to provide computing resources on-demand to cloud users efficiently, through making data centers as friendly to the environment as possible, by reducing data center energy consumption and carbon emissions. With the massive growth of high performance computational services and applications, huge investment is required to build large scale data centers with thousands o f centers and computing model. Large scale data centers consume enormous amount s of electrical energy. The computational intensity involved in data center is likely to dramatically increase the difference between the amount of energy required for peak periods and of T-peak periods in a cloud computing data center. In addition to the overwhelming operational cost, the overheating caused by high power consumption will affect the reliability o f machines and hence reduce their lifetime. There fore, in order to make the best u e of precious electricity resources, it is important to know how much energy will be required under a certain circumstance in a data center. Consequently, this dissertation addresses the challenge by developing and energy-efficient model and a defragmentation algorithm. We further develop an efficient energy usage metric to calculate the power consumption along with a Load Balancing Virtual Machine Aware Model for improving delivery of no-demand resource in a cloud-computing environment. The load balancing model supports the reduction of energy consumption and helps to improve quality of service. An experimental design was carried out using cloud analyst as a simulation tool. The results obtained show that the LBVMA model and throttled load balancing algorithm consumed less energy. Also, the quality or service in terms of response time is much better for data centers that have more physical machines. but memory configurations at higher frequencies consume more energy. Additionally, while using the LBVMA model in conjunction with the throttled load balancing algorithm, less energy is consumed. meaning less carbon is produced by the data center.

▼ User modelling in Exploratory Learning Environments (ELEs) is an emerging field with several challenges to be addressed. Due to the freedom given to learners, the amount of information generated is very large, making the modelling process very challenging. Consequently, only relevant information should be used in the user modelling process. This, however, leads to other challenges such as identification of relevant information, finding an optimal knowledge representation and defining an inference mechanism by which this knowledge is used in diagnosing the learner. This thesis addresses the challenges of user modelling in ELEs by monitoring learners' behaviour and taking into account only relevant actions in the context of an ELE for the domain of mathematical generalisation. An iterative approach was used, in line with the iterative design of the ELE. The modelling mechanism employed a modified version of Case-based Reasoning (CBR) and was evaluated using pedagogical scenarios and data from simulated and real students. This approach has the advantage of storing only relevant information and allows learner diagnosis during as well as at the end of a task. The user model was further exploited to support learning related activities, such as prioritising feedback and grouping for collaboration. For feedback prioritisation, a mechanism based on Multi-criteria Decision Making was developed and tested with the help of educational experts. The grouping for collaboration approach was inspired from Group Technology, a method from cellular manufacturing systems, and its testing showed it produces meaningful groups. Both the feedback prioritisation and the grouping for collaboration mechanisms propose solutions that are particularly relevant for ELEs by considering pertinent criteria for this type of learning. To ensure optimal coverage of the knowledge base, the user modelling approach was enhanced with adaptive mechanisms for expanding the knowledge base, which was tested on real and simulated data. This approach ensures that learner diagnostic is possible when the initial knowledge base is small and/or new behaviours are encountered over time.

▼ Aim. The aim of this study was to contribute to the building of effective and efficient methods to predict adverse clinical outcome. It has been done by developing risk of mortality and early warning score models using routinely collected data that are available from hospital computer systems. Methods. To predict risk of mortality, firstly we used logistic regression using (Biochemistry and Haematology Outcome Model - BHOM dataset) to generate a model, and the performance of each model was then compared using discrimination (AUROC or c-index) and calibration (the Hosmer- Lemeshow test). Secondly, we focused on decision trees (DT) to be compared with logistic regression (LR). In addition, we used cross validation to compare LR with other various machine learning methods. We developed early warning score algorithmically using decision trees (DTEWS) using vital sign dataset and compared the performance of DTEWS with other EWSs based on clinical expertise using c index, early warning score efficiency curve and distribution score. We also compared DTEWS with another EWS based on statistics and applied DTEWS to BHOM dataset. Results. In BHOM dataset, there were 9497 adult hospital discharges, and it was divided into four subsets. A model was built using one training set and then applied to three other testing data sets. The model in logistic regression satisfied both discrimination and calibration value when the c-index in the range 0.700-0.800 is reasonable discrimination and the p-value > 0.05 indicates there is no evidence of significant lack of fit. We also found that decision trees gave a satisfactory result followed by some other machine learning methods.Using a large vital signs dataset (n = 198,755 observation sets) from acute medical admissions, DTEWS can provide a discrimination (c-index) as good as other EWSs, has a better c-index, and also is better in other measurements including EWS efficiency curve, and distribution of score. We found DTEWS can also be applied to BHOM dataset with satisfactory results. Conclusion. The results of this study support the idea that decision trees can be applied to medical problems. When we produced a model for risk of mortality, we have shown that the decision trees model has reasonable discrimination and could be considered as an alternative technique to logistic regression. We have shown that a structured methodology using decision trees to develop early warning score has satisfactory result and contributes additional evidence that suggests an algorithmical method can be employed to quickly produce EWSs for employment in particular types of medical purpose.
