▼ The purpose of this research is to investigate the research problem: Why does emergent usage occur in adaptive information systems? Being motivated to explore this phenomenon from the experiential perspective, three research questions were posed: (1) What experiential factors describe emergent usage of adaptive information systems? (2) What generative mechanisms must exist for such emergent usage to be possible?" (3) What explains the relations of the mechanisms to effect emergent usage of such information systems? Emergent usage of adaptive information systems, predominantly accessed with smart mobile devices has become pervasive. The research problem, therefore, arises as a result of the continued under-theorization of emergent usage of adaptive information systems and lack of theory to explain why such usage occurs. To answer the research questions, an intensive single organization case-study, underpinned by critical realism, was deployed. The research explored an adaptive e-financial system developed by the case organization for public use. The research was aimed at identifying the causal mechanisms and the enabling contextual conditions that explain the system's emergent usage and the experiential factors that describe such usage. Multiple sources of qualitative data, namely, participant observation, interviews, and photography were used to collect data between 2012 and 2014. The retroductive data analysis employed a research model which was developed from a theoretical redescription of the phenomenon using a conceptual framework synthesized from literature and theories of complex adaptive systems (CAS) and meta-design. The findings were encapsulated in a concluding model termed, the Technology Emergent Usage Model (TEUM), as the key theoretical contribution of this thesis. TEUM is an explanatory case specific mid-range theory. The theory's relevance is based on its openness to flexible interpretation when applied to different contexts in future research, without making claim to its universality. Other contributions include methodological and practical contributions to highlight an area where there has been little or no empirical research to date.

▼ Coordinating multiple robots to achieve a complex task requires solving two distinct control problems: the high-level control problem of ensuring that each robot aims to perform a useful task (e.g., coordination) and the low-level control problem of ensuring that each robot actually performs the correct actions to achieve its task (e.g., navigation and locomotion). Though addressing both problems simultaneously with one algorithm is appealing, this is often difficult to impossible in domains requiring a combination of complex actions (goal selection, navigation, obstacle avoidance). This thesis establishes a hierarchical control structure, presents an adaptive navigation method, compares it to reactive navigation, and applies established adaptive coordination techniques under severe restrictions. The development and experimentation process produced results showing the following: 1) Hierarchical control structure proves effective and useful for use on resource limited robotic platforms allowing the subsequent navigation and coordination analyses to be addressed individually. 2) Adaptive navigation is an effective approach for dense environments with limited and noisy sensing, providing improvement over reactive navigation by up to 75%. 3) The application of an abstract difference objective function to training for coordination remains effective under limited information and physical robot motion restrictions, outperforming traditional system or local objectives by up to 50%. Specifically, this work establishes that neuro-evolutionary methods are applicable and beneficial both for the discovery of successful navigation techniques, as well as for the generation of coordination behavior in realistic multi-robot teams where individuals are strongly limited in sensing, communication, and computational ability. Possible extensions include increased levels of communication among individuals as well as configuring individual sensing abilities for heterogeneous teams.

▼ Distributed applications executing in uncertain environments, like the Internet, need to make timing/synchrony assumptions (for instance, about the maximum message transmission delay), in order to make progress. In the case of adaptive systems these temporal bounds should be computed at runtime, using probabilistic or specifically designed ad hoc approaches, typically with the objective of improving the application performance. From a dependability perspective, however, the concern is to secure some properties on which the application can rely. This thesis addresses the problem of supporting adaptive systems and applications in stochastic environments, from a dependability perspective: maintaining the correctness of system properties after adaptation. The idea behind dependable adaptation consists in ensuring that the assumed bounds for fundamental variables (e.g., network delays) are secured with a known and constant probability. Assuming that during its lifetime a system alternates periods where its temporal behavior is well characterized (stable phases), with transition periods where a variation of the network conditions occurs (transient phases), the proposed approach is based on the following: if the environment is generically characterized in analytical terms and it is possible to detect the alternation of these stable and transient phases, then it is possible to effectively and dependably adapt applications. Based on this idea, the thesis introduces Adaptare, a framework for supporting dependable adaptation in stochastic environments. An extensive evaluation of Adaptare is provided, assessing the correctness and effectiveness of the implemented mechanisms. The results indicate that the proposed strategies and methodologies are indeed effective to support dependable adaptation of distributed systems and applications. Finally, the applicability of Adaptare is evaluated in the context of two fundamental problems in distributed systems: consensus and failure detection. The thesis proposes solutions for these problems based on modular architectures in which Adaptare is used as a middleware for dependable adaptation of assumed timeouts.

Research Doctorate - Doctor of Philosophy (PhD)

Open learning is a new form of online education that allows resources, modules and courses to be freely, or at a minimal cost, available on the Internet. Recently, various initiatives of Open Learning Environments (OLEs), such as EdX and Coursera, have emerged and have been widely accepted all over the world. These types of OLEs are still in their early stages of evolution with many challenges and concerns that require immediate research investigation and exploration. The research on which this thesis reports has been undertaken on the belief that a number of these issues can be addressed through the consideration of cognitive science and learning theories, as well as the utilisation of contemporary technological advancements. Two specific challenges in OLEs are at the centre of this inquiry: cognitive overload that results from the presentation of learning concepts; and lack of personalisation and adaptivity to individual learner needs and preferences. A comprehensive review of the literature reveals that applying the concept of schema theory through the use of knowledge maps offers possibilities for supporting self-regulated learning, and that considering the theory of learning styles could be a successful approach for personalising learning environments and building adaptive systems. A conceptual framework for an OLE has been designed with two main features: the use of knowledge maps; and the adaptivity to individual learning styles using adaptive navigational support technology. A prototype ‘Cloud Adaptive Learning Courses’ (CALC) has been developed to investigate the helpfulness and impact of the proposed features in OLEs. The evaluation was completed by applying the prototype on courses at the University of Newcastle in which undergraduate students tried CALC and provided their perspectives on its helpfulness through online questionnaires. In addition, the adaptivity in CALC was evaluated by assessing the precision of identifying learning styles and the impact on students’ performance in terms of the time spent on learning and the access and navigation patterns. The results of these evaluations have shown that the use of knowledge maps and the adaptivity to learning styles in OLEs are promising as they have been found helpful and supportive to self-regulated learners. It is anticipated that the findings and results of this research will contribute to the development of enhanced future models of OLEs.

The complexity of software systems is exploding, along with their use and application in new domains. Managing this complexity has become a focal point for research in Software Engineering. One direction for research in this area is developing techniques for designing adaptive software systems that self-optimize, self-repair, self-configure and self-protect, thereby reducing maintenance costs, while improving quality of service. This thesis presents a requirements-driven approach for developing adaptive and customizable systems. Requirements goal models are used as a basis for capturing problem variability, leading to software designs that support a space of possible behaviours – all delivering the same functionality. This space can be exploited at system deployment time to customize the system on the basis of user preferences. It can also be used at runtime to support system adaptation if the current behaviour of the running system is deemed to be unsatisfactory. The contributions of the thesis include a framework for systematically generating designs from high-variability goal models. Three complementary design views are generated: configurational view (feature model), behavioural view (statecharts) and an architectural view (parameterized architecture). The framework is also applied to the field of business process management for intuitive high-level process customization. In addition, the thesis proposes a modeling framework for capturing domain variability through contexts and applies it to goal models. A single goal model is used to capture requirements variations in different contexts. Models for particular contexts can then be automatically generated from this global requirements model. As well, the thesis proposes a new class of requirements-about-requirements called awareness requirements. Awareness requirements are naturally operationalized through feedback controllers – the core mechanisms of every adaptive system. The thesis presents an approach for systematically designing monitoring, analysis/diagnosis, and compensation components of a feedback controller, given a set of awareness requirements. Situations requiring adaptation are explicitly captured using contexts.

▼ The problem of parameter and state estimation of a class of nonlinear systems is addressed. An adaptive identifier and observer are used to estimate the parameters and the state variables simultaneously. The proposed method is derived using a new formulation. Uncertainty sets are defined for the parameters and a set of auxiliary variables for the state variables. An algorithm is developed to update these sets using the available information. The algorithm proposed guarantees the convergence of parameters and the state variables to their true value. In addition to its application in difficult estimation problems, the algorithm has also been adapted to handle fault detection problems. The technique of estimation is applied to two broad classes of systems. The first involves a class of continuous time nonlinear systems subject to bounded unknown exogenous disturbance with constant parameters. Using the proposed set-based adaptive estimation, the parameters are updated only when an improvement in the precision of the parameter estimates can be guaranteed. The formulation provides robustness to parameter estimation error and bounded disturbance. The parameter uncertainty set and the uncertainty associated with an auxiliary variable is updated such that the set is guaranteed to contain the unknown true values. The second class of system considered is a class of nonlinear systems with timevarying parameters. Using a generalization of the set-based adaptive estimation technique proposed, the estimates of the parameters and state are updated to guarantee convergence to a neighborhood of their true value. The algorithm proposed can also be extended to detect the fault in the system, injected by drastic change in the time-varying parameter values. To study the practical applicability of the developed method, the estimation of state variables and time-varying parameters of salt in a stirred tank process has been performed. The results of the experimental application demonstrate the ability of the proposed techniques to estimate the state variables and time-varying parameters of an uncertain practical system.

▼ Adaptive control is an approach used to deal with systems with uncertain or time-varying parameters. A classical adaptive controller typically consists of a linear time-invariant (LTI) control law together with a tuning mechanism which adjusts its parameters. Usually, though not exclusively, discrete-time adaptive controllers provide only asymptotic stability and possibly bounded-noise bounded-state stability; neither exponential stability nor a bounded noise gain is typically proven. Recently it has been shown that if we employ a parameter estimator based on the original Projection Algorithm together with projecting the parameter estimates onto a given compact and convex set, then the adaptive controller guarantees linear-like closed-loop behavior: exponential stability, a bounded noise gain and a convolution bound on the exogenous inputs. In this thesis, the overarching objective is to show that we can prove these same desirable linear-like properties in a wide range of adaptive control problems without the convexity assumption: the main idea is to use multiple estimators and a switching algorithm. Indeed, we show that those properties arise in a surprisingly natural way. We first prove a general result that exponential stability and a convolution bound on the closed-loop behavior can be leveraged to show tolerance to a degree of time-variations and unmodelled dynamics, i.e. such closed-loop properties guarantee robustness. After reviewing the original Projection Algorithm and introducing the reader to our slightly revised version, we turn our attention to controller design, with a focus on a non-convex set of plant uncertainty. As a starting point, we first consider first-order plants incorporating a simple switching algorithm. We then extend the approach to a class of nonlinear plants (which have stable zero dynamics); we consider both cases of convex and non-convex sets of parameter uncertainty. Afterwards, we turn to possibly non-minimum phase LTI plants; first we consider the stabilization problem for which we have two convex sets of uncertainty; then, we turn to the problem of tracking the sum of a finite number of sinusoids of known frequencies subject to an unknown plant order and a general compact set of uncertainty.

▼ The thesis applies complex dynamic system thinking to the context of place, people and policy. The thesis aims to contribute to closing an identified gap in policy literature and practice; specifically exploring the theoretical and practical advantages of a policy development model that is more reflective of contextual reality. This research explores and demonstrates the development of policy with a particular focus on place and people. The application of dynamic systems management to place, people, and policy is made viable through the development of a meta-framework that connects dimensions and their associated multiple perspectives. In particular, the thesis demonstrates how the use of a metaframework can assist the representation, understanding, explanation and utilisation of the complexity derived from societal connections, dynamics and contestability to create value through the design, implementation and evaluation of policy. The combination of information and the meta-framework structure supports a narrative that links cause with effect at and between both the practice and strategic dimensions across activities and outcomes that are relevant to people. It further allows, and arguably requires, interests to generate narratives within similar constructs as the basis for community conversations. The meta-framework is first elaborated and then applied to cases studies in different policy arenas. The case studies demonstrate the extension of what may simply be seen as a heuristic device for policy analysis into dynamic applications within place-based development. The cases combine literature with practice to reflect differing contexts: • socio-economic pathways to new sectoral and community futures; • industry fit to place, emerging values and thinking; and • combining latent endogenous capital with emerging macro trends/policy to create new opportunity. The analysis of the case studies supports the proposition that the introduction of a dynamic systems logic meta-framework into public policy making: • can provide a framework within which to apply and further develop concepts and tools that are useful in supporting the integration of multiple perspectives and complexity thinking; • can improve public policy performance and productivity, and contribute to improved resource allocation, and measurement of success; and • can support the proposition that understanding complexity provides the potential to identify innovative policy initiatives.

▼ In the era of Cloud Computing, services and computational power are provided in an as a Service (aaS) fashion, reducing the need of buying, building and maintaining proprietary systems. In the last few years, many services moved from being proprietary to the as a Service paradigm: this, together with virtualization techniques, allows multiple applications to easily run on the same machine. However, the burden of costs optimization is left to the Cloud Provider, that still faces the problem of consolidating multiple workloads on the same infrastructure. As power consumption remains one of the most impacting costs of any digital system, several approaches have been explored in literature to cope with power caps, trying to maximize the performance of the hosted applications. These approaches were usually classified in two macro families, the software and hardware techniques. The former family is typically adopted when the goal consists in minimizing the power consumption, while providing the best possible performance for the running workloads. This approaches are characterized by obtaining high efficiency, but lacks in timeliness. Instead, the latter family is exploited when there are strict constraints regarding the power budget and the main goal consists in respecting them, while trying to maximize the performance of the running applications. In this case, the main characteristic consists in respecting the concept of timeliness, totally neglecting the concept of efficiency. In this thesis, we present results and opportunities obtained towards a performance- aware power capping orchestrator for the Xen hypervisor, that exploit a novel emerging family introduced in the literature: the hybrid approach. This fresh set of techniques aims to adopt synergically and concurrently both hardware and software approaches in order to achieve at the same time the concept of efficiency and timeliness, masking the weak spots of the two common approaches when adopter alone. The proposed solution, called XeMPUPiL, uses the Intel RAPL hardware interface to set a strict limit on the processor’s power consumption, while a software-level ODA control loop performs an exploration of the available resource allocations to find the most power efficient one for the running workload. We show how XeMPUPiL is able to achieve higher performance under different power caps for almost all the different classes of benchmarks analyzed (e.g., CPU-, memory- and IO-bound).

▼ Collective Adaptive Systems (CAS) are composed of individual agents with internal knowledge and rules which organize themselves into ensembles. These ensembles can often be observed to exhibit behaviour resembling that of a single entity with a clear goal and a consistent internal knowledge, even when the individual agents within the ensemble are not managed by any outside, globally-accessible entity. Because of their lack of a need for centralized control which results in high robustness, CAS are commonly observed in nature - and for similar reasons are often reflected in human engineered systems. Researching the patterns of operation observed in such systems provides meaningful insight into how to design and optimise stable multiagent systems capable of withstanding adverse conditions. Formal modelling provides valuable intellectual tools which can be applied to the problem of analysis of systems by means of modelling and simulation. In this thesis we explore the modelling of CAS in which space (topology and distances) plays a significant role. Working with CARMA (Collective Adaptive Resource-sharing Markovian Agents) a formal feature-rich language for modelling stochastic CAS, we investigate a number of spatial CAS scenarios from the realm of urban planning. When components operate in a spatial context, their behaviour can be affected by where they are located in that space. For example, their location can influence the speed at which they move, and their ability to communicate with other components. Components in CARMA have internal store, and behaviour expressed by Markov processes. They can communicate with each other through sending messages on state transitions in a unicast or broadcast fashion. Simulation with pseudo-random events can be used to obtain values of measures applied to CARMA models, providing a basis for analysis and optimisation. The CARMA models developed in the case studies are data-driven and the results of simulating these models are compared with real-world data. In particular, we explore two scenarios: crowd-routing and city transportation systems. Building on top of CARMA, we also introduce CGP (CARMA Graphical Plugin), a novel graphical software tool for graphically specifying spatial CAS systems with the feature of automatic translation into CARMA models. We also supply CARMA with additional syntax structures for expressing spatial constructs.

▼ Recent advances in information and communications technology have led to a surge in the popularity of artificial Collective Adaptive Systems (CAS). Such systems, comprised by many spatially distributed autonomous entities with decentralised control, can often achieve discernible characteristics at the global level; a phenomenon sometimes termed emergence. Examples include smart transport systems, smart electricity power grids, robot swarms, etc. The design and operational management of CAS are of vital importance because different configurations of CAS may exhibit very large variability in their performance and the quality of services they offer. However, due to their complexity caused by varying degrees of behaviour, large system scale and highly distributed nature, it is often very difficult to understand and predict the behaviour of CAS under different situations. Novel modelling and quantitative analysis methodologies are therefore required to address the challenges posed by the complexity of such systems. In this thesis, we develop a process algebraic modelling formalism that can be used to express complex dynamic behaviour of CAS and provide fast and scalable analysis techniques to investigate the dynamic behaviour and support the design and operational management of such systems. The major contributions of this thesis are: (i) development of a novel high-level formalism, PALOMA, the Process Algebra for Located Markovian Agents for the modelling of CAS. CAS specified in PALOMA can be automatically translated to their underlying mathematical models called Population Continuous-Time Markov Chains (PCTMCs). (ii) development of an automatic moment-closure approximation method which can provide rapid Ordinary Differential Equation-based analysis of PALOMA models. (iii) development of an automatic model reduction algorithm for the speed up of stochastic simulation of PALOMA/PCTMC models. (iv) presenting a case study, predicting bike availability in stations of Santander Cycles, the public bike-sharing system in London, to show that our techniques are well-suited for analysing real CAS.

▼ With years of work on control systems, lots of control tools have been created for automation in different situations. Adaptive Control was developed for the models with unidentified but slow-varying parameters. Aiming to guarantee the stability of control systems in presence of modeling uncertainties or disturbance, Robust Control originated from methods to optimizing both performance and robustness of systems. Nevertheless, transit performance of systems remains a big problem, no matter in Adaptive Control or Robust Control. Switching/Supervisory Control was proposed to improve transit performance by adopting the most appropriate among multiple candidate controllers. After A. S. Morse established a relatively general switching scheme by introducing a concept called “weighted signals”, people tried many ways to explore more effective switching logics. The first contribution in this dissertation follows the mainstream of switching control, which covers existence and construction of multi-controllers, design of supervisors and proof of input-to-state stability based on the general theory of average dwell-time. Compared with previous work, two points deserve emphases: 1) A more general contructive method for multi-controllers, which generalizes the parametric uncertainty from scalar variables to vectors; 2) A structure of supervisor directly based on tracking errors, instead of “weighted signals”, and its input-to-state stability is guaranteed and proven. Nevertheless, logic-based switching control with finite controller coverings is only capable to partially improve performance. Such effects of improvement are not fully under our control due to potentially complicated theoretical issues. Instead of emphasizing stability in control design, the second contribution of this dissertation is the “logic-event based switching control”, which heavily relies on controllability to drag states to the positions we expected. And with a new supervisory architecture developed, switching control with on-line controller updates becomes possible to be implemented and satisfactory transit performance follows. Moreover, in order to show the advantages of the core principles, simulation and experimental results were presented in this dissertation. In a sum, the work in this dissertation presented advancement in both current area and extensions of switching control. Considering the “logic-event based switching control”, it would prove to be a promising direction in the future studies.

▼ RESUMEN: Las técnicas de estimación de canal y de adaptación de la transmisión a las condiciones del entorno son temas de interés actual al estudiar la aplicación de técnicas de diversidad en transmisión en la tercera y cuarta generación de sistemas inalámbricos. En esta tesis se realiza un análisis del impacto del error de estimación de canal y la correlación en sistemas OFDM con diversidad en transmisión basados en codificación espacio-tiempo por bloques (STBC), se proponen técnicas de estimación de canal para estos sistemas y se propone una técnica de adaptación de la transmisión mediante la selección de código espacio-tiempo. En primer lugar, una técnica sencilla de mínimos cuadrados en el dominio de la frecuencia permite la estimación de canal en sistemas con dos antenas y constelaciones complejas, y con tres o cuatro antenas y constelaciones reales o complejas, utilizando STBCs ortogonales como bloques de entrenamiento. En segundo lugar, una representación 'sobre-completa' permite hacer una estimación diferencial de canal para un sistema con tres antenas transmisoras mediante la selección a partir de un banco de posibles estimadores, basándose en la redundancia provista por la matriz de transmisión no cuadrada del código ortogonal esporádico de tasa 3/4 para tres antenas transmisoras. En el contexto de sistemas con adaptación del transmisor, la técnica propuesta de diversidad por selección adaptativa de código espacio-tiempo se basa en el estado instantáneo del vector de canal y en un conjunto de niveles umbrales hallados fuera de línea en función del período de realimentación. Los resultados indican que esta técnica proporciona buenas prestaciones en canales correlados e incorrelados. Su aplicación a sistemas OFDM ha sido estudiada, superando a técnicas de selección de antena y a otras técnicas de transmisión adaptativa.

▼ Major advancements over the last few decades in communication networks gave rise to the new paradigm of Networked Control Systems (NCSs). Within this paradigm, sensing and actuation signals are exchanged among various parts of a single system or among many subsystems via communication networks. Although this enables one to perform more complex tasks than traditional control paradigms, it comes at the cost of complicating the design phase and the required analysis tools. One of the major challenges when considering a network is quantization effect which affects the performance of any control laws that were designed without taking the network effects into account. Even if the NCS paradigm is well established, few works are available on adaptive methods for NCSs: this MSc thesis establishes novel adaptive control approaches that attain asymptotic tracking for linear systems and switched linear systems with parametric uncertainties, when input measurements are quantized due to the presence of a communication network closing the control loop. In addition to enlarging the class of systems for which the adaptive quantized control can be solved, a hybrid control policy is applied to a novel dynamic quantizer with dynamic offset to address the tracking problem. The MSc thesis is split into two parts: in the first part we consider the model reference adaptive control of a linear uncertain system, where a Lyapunov-based approach is used to derive the adaptive adjustments for the dynamic range, the dynamic offset and the control parameters. In the second part, the approach is extended to switched uncertain linear systems with dwell-time switching, where a new time-varying Lyapunov-like function is adopted: it is proven analytically that the new Lyapunov function we introduce, overcomes the need for zooming-out at every time instant in order to compensate the possible increment of the Lyapunov function. The proposed quantized adaptive control schemes are applied to two benchmark examples: an electro-hydraulic system and the piecewise linear model of the NASA GTM aircraft, respectively.

▼ An adaptive pre-clinical x-ray computed tomography system, named "FaCT" was designed, built, and tested at the University of Arizona's Center for Gamma-Ray Imaging (CGRI). The FaCT system possesses the unique ability to change its magnification and dynamically mask the x-ray beam profile. Using these two abilities, the FaCT system can adapt its configuration to the object being imaged, and the task being performed, while achieving a reduction in the radiation dose applied for imaging.Development of the system included the design of all mechanical components, motion systems, and safety systems. It also included system integration of all electronics, motors, and communication channels. Control software was developed for the system and several high-performance reconstruction algorithms were implemented on graphics processing units for reconstructing tomographic data sets acquired by the system. A new geometrical calibration method was developed for calibrating the system that makes use of the full image data gathered by the system and does not rely on markers.An adaptive imaging procedure consisting of a preliminary scout scan, human guidance, and a diagnostic quality scan was developed for imaging small volumes of interest in the interior of an object at substantially reduced dose. The adaptive imaging procedure makes use of FaCT's adjustable magnification, beam-masking capability, and high-performance reconstruction software to achieve high-quality reconstruction of a volume of interest with less dose than would be required by a traditional x-ray computed tomography system without adaptive capabilities.To address ongoing research into mathematical rules for adapting an imaging system, such as FaCT, to better perform a given estimation task, a method of quantifying a system's ability to estimate a parameter of interest in the presence of nuisance parameters based on the Fisher Information was proposed. The method requires a statistical model of object variability. Possible strategies for increasing the performance of an estimation task, given an adaptive system, were suggested.
