Streszczenie:
An overview of measured thermal performances of Danish solar combi systems in practice is given. The thermal performance varies greatly from system to system. Measured and calculated thermal performances of different solar combi systems are compared and the main reasons for the different thermal performances are given. Further, a parametric study on two solar combi system types is performed. Based on the investigation it can be concluded that the thermal performance first of all is influenced by the space heating consumption during the summer period and that the systems in practice perform as theoretically expected.

This work presents a model to investigate the inflow performance relationships (IPR) of horizontal and vertical wells in a multi-well pattern. The model can be used to compute the overall and individual well performances. It is shown that stabilized IPRs may not be sufficient for the evaluation of horizontal well performances due to prolonged transient flow periods. The results presented in this paper clearly indicate that inflow performance of wells in a multi-well pattern is a dynamic concept; and, especially in the prediction of future performances, dynamic rather than static IPR models should be used.

The paper proposes a novel learning-based coordination strategy for lateral control systems of automated vehicles. The motivation of the research is to improve the performance level of the coordinated system compared to the conventional model-based reconfigurable solutions. During vehicle maneuvers, the coordinated control system provides torque vectoring and front-wheel steering angle in order to guarantee the various lateral dynamical performances. The performance specifications are guaranteed on two levels, i.e., primary performances are guaranteed by Linear Parameter Varying (LPV) controllers, while secondary performances (e.g., economy and comfort) are maintained by a reinforcement-learning-based (RL) controller. The coordination of the control systems is carried out by a supervisor. The effectiveness of the proposed coordinated control system is illustrated through high velocity vehicle maneuvers.

Streszczenie:
Fabric systems used in firefighters' thermal protective clothing should offer optimal thermal protective and thermo-physiological comfort performances. However, fabric systems that have very high thermal protective performance have very low thermo-physiological comfort performance. As these performances are inversely related, a categorization tool based on these two performances can help to find the best balance between them. Thus, this study is aimed at developing a tool for categorizing fabric systems used in protective clothing. For this, a set of commercially available fabric systems were evaluated and categorized. The thermal protective and thermo-physiological comfort performances were measured by standard tests and indexed into a normalized scale between 0 (low performance) and 1 (high performance). The indices dataset was first divided into three clusters by using the k-means algorithm. Here, each cluster had a centroid representing a typical Thermal Protective Performance Index (TPPI) value and a typical Thermo-physiological Comfort Performance Index (TCPI) value. By using the ISO 11612:2015 and EN 469:2014 guidelines related to the TPPI requirements, the clustered fabric systems were divided into two groups: Group 1 (high thermal protective performance-based fabric systems) and Group 2 (low thermal protective performance-based fabric systems). The fabric systems in each of these TPPI groups were further categorized based on the typical TCPI values obtained from the k-means clustering algorithm. In this study, these categorized fabric systems showed either high or low thermal protective performance with low, medium, or high thermo-physiological comfort performance. Finally, a tool for using these categorized fabric systems was prepared and presented graphically. The allocations of the fabric systems within the categorization tool have been verified based on their properties (e.g., thermal resistance, weight, evaporative resistance) and construction parameters (e.g., woven, nonwoven, layers), which significantly affect the performance. In this way, we identified key characteristics among the categorized fabric systems which can be used to upgrade or develop high-performance fabric systems. Overall, the categorization tool developed in this study could help clothing manufacturers or textile engineers select and/or develop appropriate fabric systems with maximum thermal protective performance and thermo-physiological comfort performance. Thermal protective clothing manufactured using this type of newly developed fabric system could provide better occupational health and safety for firefighters.

Streszczenie:
This thesis work is about the realization of hardware and software systems for Quantum Random Number Generation (QRNG) and Quantum Key Distribution (QKD). Such systems were developed to guarantee a full functionality for a broader investigation of these two cutting edge applications of Quantum Information field. The thesis describes in details both the hardware and the software that were developed for FPGA-CPU board, Time-to-Digital converter (TDC) devices and computers, along with QRNG and QKD specific applications and their results. Randy was the first FPGA-based QRNG device to be developed; it uses a light source attenuated to single-photon level and one single-photon avalanche diode (SPAD). From the sampling of the SPAD electrical signal, the device produces random numbers through dedicated generation protocols and through the Peres unbiasing algorithm in order to maximize the output generation bit rate. Furthermore, the device allows to generate real time random numbers. This feature is used for the time setting of electro-optical components for extending Wheeler’s delayed-choice experiment to space. The same techniques were applied to a second device, LinoSPAD; it combines an FPGA-chip and a CMOS-SPADs array. Moreover, in this device, a TDC improves the photon detection time accuracy. Along with a dedicated post-processing based on Zhou-Bruk algorithm, the TDC allowed to reach a final bit rate equivalent to 300 Mbit/s. As far as QKD systems are concerned, within the collaboration among the University of Padova, the Italian Space Agency (ASI) with the Matera Laser Ranging Observatory (MLRO) and the Chinese Academy of Sciences (CAS) a TDC device management software was developed. The project aim is to realize a quantum cryptographic key exchange between the Chinese satellite Micius and MLRO. The software was designed to manage the entire data acquisition synchronized with UTC time. Furthermore, another software was designed to deal with electro-optomechanical and electro-optical components. The software is aim at the time-variant compensation of the beam angular changes through the optical path. Once again, within a collaboration between ASI and University of Padova, a full free space QKD system over tenths of kilometers was developed. It required the design of various components. This work describes the QKD source along with the dedicated FPGA board design. Such board generates the electrical impulses to control the qubit laser along with the electro-optic phase and intensity modulators.
Il presente lavoro di tesi tratta la realizzazione di sistemi hardware e software per Quantum Random Number Generation (QRNG) e Quantum Key Distribution (QKD). Tali sistemi sono stati sviluppati al fine di garantire una completa funzionalità per l’investigazione a tutto campo di queste due applicazioni che ad oggi risultano essere le più promettenti nell’ambito della Quantum Information. Vengono presentati in dettaglio sia l’hardware sia i software utilizzati che sono stati sviluppati per schede FPGA-CPU, dispositivi di Time-to-Digital converter (TDC) e computer. Vengono inoltre descritte le applicazioni specifiche di QRNG e QKD assieme ai risultati ottenuti. Randy è stato il primo dispositivo QRNG sviluppato su scheda FPGA e utilizza una sorgente luminosa attenuata a singolo fotone e un single-photon avalanche diode (SPAD). A partire dal campionamento del segnale elettrico dello SPAD, il dispositivo produce numeri randomici tramite protocolli di generazione appositi e tramite l’applicazione dell’algoritmo di unbiasing di Peres per massimizzare il bit rate. Il dispositivo permette inoltre di generare numeri randomici in tempo reale. Questa caratteristica viene utilizzata per la gestione temporizzata di componenti elettro-ottici per l’estensione allo spazio dell’esperimento a scelta ritardata di Wheeler’s. Le stesse tecniche sono state in seguito applicate ad un secondo dispositivo, LinoSPAD, che integra un chip FPGA e un array di CMOS-SPAD. Tale dispositivo prevede inoltre un TDC per aumentare la precisione temporale di dectection dei fotoni. Questa caratteristica, unita all’uso di una procedure di post-processing appositamente sviluppata e basata sull’algoritmo di Zhou-Bruk, ha permesso di raggiungere un bit rate finale pari a 300 Mbit/s. Per quanto riguarda i sistemi QKD, all’interno di un progetto di collaborazione tra l’Università di Padova, l’Agenzia Spaziale Italiana (ASI) insieme al Matera Laser Ranging Observatory (MLRO) e la Chinese Academy of Sciences (CAS) è stato sviluppato un software di gestione di un dispositivo TDC. Il progetto prevede la realizzazione di uno scambio di chiave crittografica quantistica tra il satellite cinese Micius e l’osservatorio di Matera. Il software è stato progettato per la gestione dell’intera acquisizione dati sincronizzata al tempo UTC. Inoltre è stato sviluppato anche un software per la gestione di componenti elettro-optomeccanici e elettro-ottici atti alla compensazione tempo variante delle variazioni angolari del fascio nel percorso ottico. Sempre all’interno di una collaborazione tra ASI e Università di Padova, è stato sviluppato un sistema completo di QKD free space per distanze nell’ordine di decine di chilometri. Lo sviluppo del sistema ha richiesto la progettazione di molteplici componenti. In questo lavoro viene descritta la parte della sorgente QKD e quindi della progettazione della scheda FPGA dedicata. Tale scheda ha il compito di generare gli impulsi elettrici per il controllo del laser per la produzione dei qubit e per il controllo dei modulatori di fase e di intensità elettro-ottici.

Streszczenie:
De nos jours, les systèmes distribués sont constitués de nombreuxcomposants logiciels ayant des interactions complexes et de nombreusespossibilités de configurations. Dès lors, localiser les problèmes deperformance est une tâche difficile, nécessitant une expertisehumaine et de nombreux essais. En effet, la même pile logicielle peutse comporter différemment en fonction dumatériel utilisé, de la logique applicative, des paramètres deconfiguration et des conditions de fonctionnement. Ce travail a pourobjectif (i) d’identifier un ensemble demétriques de référence, générales etfiables, pour localiser les problèmes de performance, (ii) d’identifierles caractéristiques de ces indicateurs, et (iii) deconstruire un outil qui puisse déterminer de manière automatiquesi le système a atteint sa capacité maximale en terme dedébit.Dans cette thèse, nous présentons trois contributionsprincipales. Premièrement, nous présentons une étude analytique d’ungrand nombre de configurations réalistes d’applications distribuéesmulti-tiers, se concentrant sur les chaînes de traitements desdonnées. En analysant un grand nombre de métriques au niveau logicielet matériel, nous identifions celles dont le comportement change aumoment où le système atteint sa capacité maximale. Deuxièmement, nousexploitons les techniques d’apprentissage machine pour développer unoutil capable d’identifier automatiquement les problèmes deperformance dans la chaîne de traitement de données. Pour ce faire,nous évaluons plusieurs techniques d’apprentissage machine, plusieurssélections de métriques, et différentscas de généralisation pour de nouvelles configurations. Troisièmement,pour valider les résultats obtenues sur la chaîne de traitement dedonnées, nous appliquons notre approche analytique et notre approchefondée sur l'apprentissage machine au cas d’une architecture Web.Nous tirons plusieurs conclusions de nos travaux. Premièrement, il estpossible d’identifier des métriques clés qui sont des indicateursfiables de problèmes de performance dans les systèmes distribuésmulti-tiers. Plus précisément, identifier le moment où le serveur aatteint sa capacité maximale peut être identifier grâce à cesmétriques fiables. Contrairement à l’approche adoptée par de nombreuxtravaux existants, nos travaux démontrent qu'une combinaison demétriques de différents types est nécessaire pour assurer uneidentification fiable des problèmes de performance dans un grandnombre de configurations. Nos travaux montrent aussi que les approchesfondées sur des méthodes d’apprentissage machine pour analyser lesmétriques permettent d’identifier les problèmes de performance dansles systèmes distribués multi-tiers. La comparaison de différentsmodèles met en évidence que ceux utilisant les métriques fiablesidentifiées par notre étude analytique sont ceux qui obtiennent lameilleure précision. De plus, notre analyse approfondie montre larobustesse des modèles obtenues. En effet, ils permettent unegénéralisation à de nouvelles configurations, à de nouveaux nombres declients, et à de nouvelles configurations exécutées avec de nouveauxnombres de clients. L'extension de notre étude au cas d'unearchitecture Web confirme les résultats principaux obtenus à traversl’étude sur la chaîne de traitement de données. Ces résultats ouvrentla voie à la construction d'un outil générique pour identifier demanière fiable les problèmes de performance dans les systèmesdistribués
Today's distributed systems are made of various software componentswith complex interactions and a large number of configurationsettings. Pinpointing the performance bottlenecks is generally a non-trivial task, which requires human expertise as well as trial anderror. Moreover, the same software stack may exhibit very differentbottlenecks depending on factors such as the underlying hardware, theapplication logic, the configuration settings, and the operatingconditions. This work aims to (i) investigate whether it is possibleto identify a set of key metrics that can be used as reliable andgeneral indicators of performance bottlenecks, (ii) identify thecharacteristics of these indicators, and (iii) build a tool that canautomatically and accurately determine if the system reaches itsmaximum capacity in terms of throughput.In this thesis, we present three contributions. First, we present ananalytical study of a large number of realistic configuration setupsof multi-tier distributed applications, more specifically focusing ondata processing pipelines. By analyzing a large number of metrics atthe hardware and at the software level, we identify the ones thatexhibit changes in their behavior at the point where the systemreaches its maximum capacity. We consider these metrics as reliableindicators of performance bottlenecks. Second, we leverage machinelearning techniques to build a tool that can automatically identifyperformance bottlenecks in the data processing pipeline. We considerdifferent machine learning methods, different selections of metrics,and different cases of generalization to new setups. Third, to assessthe validity of the results obtained considering the data processingpipeline for both the analytical and the learning-based approaches,the two approaches are applied to the case of a Web stack.From our research, we draw several conclusions. First, it is possibleto identify key metrics that act as reliable indicators of performancebottlenecks for a multi-tier distributed system. More precisely,identifying when the server has reached its maximum capacity can beidentified based on these reliable metrics. Contrary to the approachadopted by many existing works, our results show that a combination ofmetrics of different types is required to ensure reliableidentification of performance bottlenecks in a large number ofsetups. We also show that approaches based on machine learningtechniques to analyze metrics can identify performance bottlenecks ina multi-tier distributed system. The comparison of different modelsshows that the ones based on the reliable metrics identified by ouranalytical study are the ones that achieve the bestaccuracy. Furthermore, our extensive analysis shows the robustness ofthe obtained models that can generalize to new setups, to new numbersof clients, and to both new setups and new numbers ofclients. Extending the analysis to a Web stack confirmsthe main findings obtained through the study of the data processingpipeline. These results pave the way towards a general and accuratetool to identify performance bottlenecks in distributed systems

Streszczenie:
Multiple-antenna systems offer significant performance enhancement and will be applied to the next generation broadband wireless communications. This thesis presents the investigations of multiple-antenna systems – multiple-input multiple-output (MIMO) and cooperative communication (CC) – and their performances in more realistic propagation environments than those reported previously. For MIMO systems, the investigations are conducted via theoretical modelling and simulations in a double-scattering environment. The results show that the variations of system performances depend on how scatterer density varies in flat fading channels, and that in frequency-selective fading channels system performances are affected by the length of the coding block as well as scatterer density. In realistic propagation environments, the fading correlation also has an impact on CC systems where the antennas can be further apart than those in MIMO systems. A general stochastic model is applied to studying the effects of fading correlation on the performances of CC systems. This model reflects the asymmetry fact of the wireless channels in a CC system. The results demonstrate the varied effects of fading correlation under different protocols and channel conditions. Performances of CC systems are further studied at the packet level, using both simulations and an experimental testbed. The results obtained have verified various performance trade-offs of the cooperative relaying network (CRN) investigated in different propagation environments. The results suggest that a proper selection of the relaying algorithms and other techniques can meet the requirements of quality of service for different applications.

Streszczenie:
Adaptation to Climate Change represents nowadays one of the main problem contemporary society has to face with, especially because of the high complexity involved in socio-ecological systems.The difficulty to manage climate variability is particularly relevant in the agricultural sector, in which key challenges are related to the behaviour of economic agents and their relationships, within the broader context of climate change adaptation. To understand how these interactions take place, represents one open and stimulating issue for decision-makers and socio-economic research.Generally we can distinguish between two different types of adaptation. Planned adaptation refers to a policy context and decisions take the form of identifying the “best option” within sets of different plausible adaptation measures. Autonomous adaptation instead concerns economic agents’ behaviour, exploring their decision processes and preferences and analyse effects at multiple scales. In such a context, to analyse and well understand interactions among different agents in contest-specific situations become fundamental, building mental models able to extricate systems' intrinsic complexity.Which is the potential role that could be played by climate services? In particular, to what extent and by which tools can improved climate information be efficiently managed and utilised to contribute to water saving?Agent-Based Modelling constitutes one of the more suitable methods in approaching those problems, being able to capture the intrinsic complexity of socio-ecosystems and, in this manner, bringing decision-makers into the right way to operate across these systems.This thesis aims to explore the potentials of climate services in adaptation to climate change, referring in particular to a case study application of ABM in agriculture field.

In this thesis, we are interested in a wide-area PLC (Power Line Communication) network to provide a communication infrastructure for monitoring and control of energy distribution and consumption. This work has been carried out as a part of REMPLI (Real-time Energy Management via Power Line and Internet) European project and resulted in the definition of REMPLI PLC. For achieving high network performance and real-time data transfer using medium voltage and low voltage electricity grids, major problems such as dynamic packet routing, quality of service management and real-time event reporting are addressed. We designed an efficient routing protocol to cope with dynamic electricity grid topology changes and to relay packets to reach the destination. REMPLI PLC performance is evaluated using simulations and complemented by analytic studies. It is proved that most of the application requirements can be satisfied by REMPLI PLC. We proposed and implemented a new traffic dispatcher providing differentiated quality of service for applications. Based on ALOHA protocol, some variants have been designed and evaluated for enabling efficient real-time event notification
Dans cette thèse, nous nous intéressons à la problématique liée à la communication numérique sur courant porteur dans l’objectif de fournir une infrastructure de communication qui permet la surveillance et le contrôle de la distribution et de la consommation de l’énergie. Ce travail a été effectué dans le cadre du projet européen REMPLI (Real-time Energy Management via Power Line and Internet) et a produit la spécification REMPLI PLC (Power Line Communication). Pour fournir une meilleure performance de la communication et effectuer le transfert de données en temps réel, en utilisant les réseaux électriques de moyenne tension et de basse tension, les problèmes principaux qui sont le routage dynamique de paquets de données, la gestion de la qualité de service et la notification des événement en temps réel, ont été traités. Nous avons développé un protocole de routage efficace pour s’adapter au changement dynamique de topologie du réseau électrique. Les performances de REMPLI PLC sont évaluées en utilisant des approches de simulation couplée avec des approches analytiques. Il est prouvé que la majorité des besoins applicatifs peuvent être satisfaite par REMPLI PLC. Nous avons proposé et implanté un nouvel “ordonnançeur de traffic” fournissant différents niveaux de qualité de service pour les applications. Des variantes de protocole ALOHA ont été proposées et évaluées afin de vérifier que les propriétés temps réel requises sur les notifications d’événements sont respectées

Streszczenie:
Recent literature on the political economy of education highlights the role of political settlements, political commitments, and features of public governance in shaping education systems’ development and performance around learning. Vietnam’s experiences provide fertile ground for the critique and further development of this literature including, especially, its efforts to understand how features of accountability relations shape education systems’ performance across time and place. Globally, Vietnam is a contemporary outlier in education, having achieved rapid gains in enrolment and strong learning outcomes at relatively low levels of income. This paper proposes that beyond such felicitous conditions as economic growth and social historical and cultural elements that valorize education, Vietnam’s distinctive combination of Leninist political commitments to education and high levels of societal engagement in the education system often works to enhance accountability within the system in ways that contribute to the system’s coherence around learning; reflecting the sense and reality that Vietnam is a country in which education is a first national priority. Importantly, these alleged elements exist alongside other features that significantly undermine the system’s coherence and performance around learning. These include, among others, the system’s incoherent patterns of decentralization, the commercialization and commodification of schooling and learning, and corresponding patterns of systemic inequality. Taken together, these features of education in Vietnam underscore how the coherence of accountability relations that shape learning outcomes are contingent on the manner in which national and local systems are embedded within their broader social environments while also raising intriguing ideas for efforts to understand the conditions under which education systems’ performance with respect to learning can be promoted, supported, and sustained.

This paper locates many of the most important strengths and weaknesses in Vietnam’s education system in the politics of education and in features of the country’s education system’s societal embedding. By the politics of education, we mean the relations of power and authority and of domination, contestation, cooperation, and accommodation that shape the functioning of the education system as an institutional field. By the societal embeddedness, we refer to the system’s interdependent relation with its broader social and institutional environment. Understanding these elements of Vietnam’s education system is of vital importance for efforts to improve education systems’ performance in Vietnam and beyond.

Streszczenie:
The disappointing performance of education systems in developing countries in improving learning outcomes has spurred research aimed at establishing what features of education systems determine their effectiveness or failure in improving learning outcomes. There has been special interest in the challenge of making education systems more coherent for learning, i.e., developing systems in which accountability relations among stakeholders across key elements of education policy design support and sustain strong learning outcomes. In the emergent literature on the political economy of education, a great deal of attention has been directed at Vietnam, a lower-middle income country whose results on assessments of learning have been vastly higher than all other countries in its income group and have even surpassed learning assessment results of many OECD countries. This has led to a raft of research papers asking, “how did Vietnam do it?” Addressing this question, this paper explores Vietnam’s education system’s coherence for learning through an analysis of accountability relations across three key elements of education policy design — delegation, finance, and information. Our aim is to ascertain how features of these policy elements’ practice may variously support or undermine the Communist Party of Vietnam’s objective of promoting quality education and improved learning outcomes for all. The potentially surprising answer to the “how coherent” question posed in the title is, not really that much. Analysis finds that Vietnam’s education system remains weakly "coherent around learning" and is best understood as a “formal process compliant” system that, despite its many strengths, is nonetheless underperforming relative to its potential. The implications of this for efforts to enhance the system’s performance around learning are explored in brief.

The first report prepared under the Turkey of the Future project is on education, where our country has long been in a search for stability and methodology. The report aims to realistically study in 2018 what needs to be accomplished when looking forward to 2030 using quantitative and qualitative data. In this context, the study begins by explaining the state of education in the new millennium and the problems experienced from this perspective. The context necessary in resolving the issues and bettering current circumstances has been also emphasized in the purview of the report. Along with these improvements, students’ national and international examination performances are also analyzed. Finally, the developed policies, solution recommendations, and improvements have been presented in 12 points on the vision of the future. In preparing the report, the primary framework has been shaped by the relevant scientific literature, the framework and principal values established by the İLKE Foundation for Science, Culture and Education within the scope of the Turkey of the Future Project, and the educational perspectives of the research team. Besides multidisciplinarity and systems approach, locality and originality have been the two principal values when preparing this report.

Streszczenie:
Reliable vehicle start is necessary to support mission success, especially for response time. At Department of Defense installations in cold regions, vehicles using rechargeable battery and starter technologies have significant issues starting in the cold. Ultracapacitor engine start modules (ESMs) are an alternate technology to rechargeable lead-acid or lithium-ion batteries. The project develops a performance baseline for the ESM used in the M1126 Stryker Combat Vehicle under cold conditions. To test the performance of the ESMs in a cold room, a mechanical load system was constructed to replicate the load of starting a Stryker engine and instrumented with sensors to monitor parameters such as voltage, torque, and temperature. The ESMs were tested with the load system at temperatures from 24°C to −40°C. The results of the tests showed that there was some degradation of the ultracapacitor’s performance at the colder temperatures, which was expected, but no permanent damage. This work provides a test protocol and capability to evaluate next-generation vehicle battery systems for cold regions applications. Additionally, the ESM cold performance data establish a baseline to compare next-generation vehicle battery storage systems and to support cold regions missions and identify potential performance requirements for future vehicle battery system acquisition.
