Abstract:
This thesis work aimed to develop solar Photovoltaic (PV) powered smart street post. The post was set to serve on highways for wild animals’ detection and warn vehicles of possible crossings. The main aim was to design reliable standalone PV system via PVSyst software and experimenting four different PV technologies including a bifacial module under. Another aim was to select and develop the hardware and software terms of the smart street pot. Radar sensor and analog to digital (A/D) data acquisition (DAQ) card were set to be used for the motion detection. RF wireless communication module was used for communicating with nearby posts to send data and trigger warning light emitting diodes (LED) sign. A Raspberry Pi microcontroller was programmed to control the operation of the street post through processing the signal from radar sensor and communicating with nearby posts. The PV system design included generation of street post’s daily profile, sizing and selection of the components of the system including the module, battery, charge controller and power stage circuit. The later was designed to provide suitable voltage level and interface for the loads connected. PVSyst model was built and set to be located in Ulm, Germany. The design parameters were set, and different set of orientations were tested for each module. The simulation results showed bifacial module delivered a reliable PV system in case of south and south-east orientation and achieved better performance in other orientations in comparison to the other PV modules implemented. Due to limitations in PVSyst software the results provided had an overall uncertainty of 5%. The microcontroller was able to process the data from the radar sensor and DAQ card and perform fast Fourier transform (FFT). However, further processing of motion detection was complex to be included in the thesis work. The radar sensor and DAQ card provided signals with uncertainty of ± 3.4 mV. The RF wireless communication module transmitted signal over various ranges up to 150 m with time delay of 500 ms.

Abstract:
This paper focuses on the regional empty container repositioning problem. We propose a more practical model to optimize regional empty container movements. With the framework, we evaluate the effectiveness of “street-turn” strategy and provide insights on “street-turn” operation in Metro Vancouver area. We conduct interviews with local industry professionals to collect information about current empty container operations. The major findings from this research are: (1) “Street-turn” strategy reduces empty container repositioning cost majorly from transportation and gate fees. (2) “Street-turn” strategy is more effective in trade-balanced environment than trade-imbalanced environment. (3) The number of participants in the transport network has a positive impact on the feasibility and effectiveness of “street-turn” strategy. (4) The variance in the supply and demand of empty containers increases the variance in the effectiveness of “street-turn” strategy. (5) Container users have higher incentive to promote “street-turn” operations than shipping lines. (6) “Street-turn” strategy has been conducted jointly by a few importers and exporters in Metro Vancouver area. The major challenge is that container information is not shared among participants. (7) Unlike the situation in LA/LB port region, shipping lines have not yet taken the initiative to promote “street-turn” interchanges in Metro Vancouver area. The successful implementation of “street-turn” strategy depends on the participation of each player. With a high level of information visibility, the proposed model can be employed as a decision support tool to identify “street-turn” opportunities and optimize empty container movements within the system.Business, Sauder School of

This research project builds upon previous work related to intelligent and energy efficient lighting in modern street and outdoor lighting systems. The concept of implementing modern smart grid technologies such as the proposed Street & Outdoor Lighting Intelligent Monitoring System (SOLIMS) is developed. A random sample of photocells from two municipal electric power systems is used to collect data of the actual on/off times of random photocells versus Civil Twilight (sunrise/sunset) times. A business case was developed using the data collected from the observations to support an electric utility company’s implementation of SOLIMS as an alternative to current operations. The goal of the business case is to demonstrate energy and capacity savings, reduced maintenance and operating costs, and lower carbon emissions.

Adedokun, Adeyemi. "Application of Road Infrastructure Safety Assessment Methods at Intersections." Thesis, Linköpings universitet, Kommunikations- och transportsystem, 2016. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-127334.
Abstract:
Traffic safety at intersections is a particularly difficult phenomenon to study, given the fact that accidents occur randomly in time and space thereby making short-term measurement, assessment and comparison difficult. The EU directive 2008/96/EC introduced road infrastructure safety management, which offers a five layer structure for developing safer road infrastructure has been used to develop tools for accident prediction and black spot management analysis which has been applied in this work to assess the safety level of intersections in Norrköping city in Sweden. Accident data history from STRADA (Swedish Traffic Accident Data Acquisition) and the network demand model for Norrköping city were used to model black spots and predict the expected number of accidents at intersections using PTV Visum Safety tool, after STRADA accident classification was restructured and the Swedish accident prediction model (APM) was configured and tested to work within the tool using the model from the Swedish road administration (SRA). The performance of the default (Swiss) and the Swedish APM was compared and identified locations with the high accident records, predicted accident counts and traffic volumes were audited using qualitative assessment checklist from Street-Audit tool. The results from these methods were analysed, validated and compared. This work provides recommendations on the used quantitative and qualitative methods to prevent accident occurrence at the identified locations.

Friedman, Kayla Simone. "Examining English planning as a barrier to the thermal improvement of conservation properties." Thesis, University of Cambridge, 2015. https://www.repository.cam.ac.uk/handle/1810/284392.
Abstract:
This dissertation examines why planning is perceived as a barrier to the thermal improvement of conservation properties, and considers ways in which this might be addressed. The focus on thermal improvement is derived from a survey of UK scenario literature for energy management up to 2050. A further examination of the literature finds that conservation properties are particularly in need of thermal improvement; and barriers to thermal improvement are identified. A gap in the academic knowledge is found that identifies planning as a perceived barrier, but that there is no investigation of this widely held perception. The research question is therefore developed as, 'Why is English planning perceived as a barrier to the thermal improvement of conservation properties and how can it be addressed?' The dissertation methodology uses a pragmatic mixed-methods approach and research design. The first phase of the research examines 'Why planning is perceived as a barrier', by using surveys and interviews to gather evidence of the experiences and opinions of the multiple users of planning for conservation projects. Through this work, a lack of consistency and reliability in English planning is identified. The data suggests this may be due to the discretionary and fragmented nature of the English planning system which requires local authorities to interpret national policies and develop local plans and guidance. This results in local decision-making, which may not be consistent. Additionally, the research finds a perceived lack of strong national policy and guidance. This perceived lack of consistency and reliability in the application of planning is selected as the basis for validation phase of the dissertation research findings. The validation research seeks to test the perception of a lack of consistency and reliability through a Comparative Information Quality assessment adapted and developed from the discipline of Information Management. Online planning guidance for conservation projects provided by 13 London Councils is compared. The method confirms and highlights areas of inconsistency across the Councils' planning guidance. By identifying a number of areas of inconsistency, and by providing a tool that could help to ensure that policy is delivered consistently at the local level, this component of the research addresses the second part of the research question, 'How can the planning barrier be addressed?'. In conclusion, the dissertation suggests that planning is perceived as a barrier due to a lack of consistency and reliability in the planning process. Inconsistencies are identified and a recommendation is made for how these might be reduced.

Abstract:
The Main Street Four Point Approach to commercial revitalization has been applied successfully in thousands of communities across the U.S. Starting in 1995, citywide coordinated programs began applying the balanced points of organization, design, economic restructuring and promotion to urban environments. This thesis focuses on the opportunities and challenges present in five citywide Main Street programs in Boston, Baltimore, Washington D.C., Orlando and Portland through quantitative inquiry and interviews with program administrators. This thesis discusses density, capacity, volunteerism, vernacular culture, and politics as emergent themes of the urban application of the Main Street Approach and recommends expanding the breadth of definition and flexibility of each of the Four Points as to be more applicable and successful in the citywide context.

Liu, Xintao. "The Principle of Scaling of Geographic Space and its Application in Urban Studies." Doctoral thesis, KTH, Geodesi och geoinformatik, 2012. http://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-90832.
Abstract:
Geographic space is the large-scale and continuous space that encircles the earth and in which human activities occur. The study of geographic space has drawn attention in many different fields and has been applied in a variety of studies, including those on cognition, urban planning and navigation systems. A scaling property indicates that small objects are far more numerous than large ones, i.e., the size of objects is extremely diverse. The concept of scaling resembles a fractal in geometric terms and a power law distribution from the perspective of statistical physics, but it is different from both in terms of application. Combining the concepts of geographic space and scaling, this thesis proposes the concept of the scaling of geographic space, which refers to the phenomenon that small geographic objects or representations are far more numerous than large ones. From the perspectives of statistics and mathematics, the scaling of geographic space can be characterized by the fact that the sizes of geographic objects follow heavy-tailed distributions, i.e., the special non-linear relationships between variables and their probability. In this thesis, the heavy-tailed distributions refer to the power law, lognormal, exponential, power law with an exponential cutoff and stretched exponential. The first three are the basic distributions, and the last two are their degenerate versions. If the measurements of the geographic objects follow a heavy-tailed distribution, then their mean value can divide them into two groups: large ones (a low percentage) whose values lie above the mean value and small ones (a high percentage) whose values lie below. This regularity is termed as the head/tail division rule. That is, a two-tier hierarchical structure can be obtained naturally. The scaling property of geographic space and the head/tail division rule are verified at city and country levels from the perspectives of axial lines and blocks, respectively. In the study of geographic space, the most important concept is geographic representation, which represents or partitions a large-scale geographic space into numerous small pieces, e.g., vector and raster data in conventional spatial analysis. In a different context, each geographic representation possesses different geographic implications and a rich partial knowledge of space. The emergence of geographic information science (GIScience) and volunteered geographic information (VGI) greatly enable the generation of new types of geographic representations. In addition to the old axial lines, this thesis generated several types of representations of geographic space: (a) blocks that were decomposed from road segments, each of which forms a minimum cycle such as city and field blocks (b) natural streets that were generated from street center lines using the Gestalt principle of good continuity; (c) new axial lines that were defined as the least number of individual straight line segments mutually intersected along natural streets; (d) the fewest-turn map direction (route) that possesses the hierarchical structure and indicates the scaling of geographic space; (e) spatio-temporal clusters of the stop points in the trajectories of large-scale floating car data. Based on the generated geographic representations, this thesis further applies the scaling property and the head/tail division rule to these representations for urban studies. First, all of the above geographic representations demonstrate the scaling property, which indicates the scaling of geographic space. Furthermore, the head/tail division rule performs well in obtaining the hierarchical structures of geographic objects. In a sense, the scaling property reveals the hierarchical structures of geographic objects. According to the above analysis and findings, several urban studies are performed as follows: (1) generate new axial lines based on natural streets for a better understanding of urban morphologies; (2) compute the fewest-turn and shortest map direction; (3) identify urban sprawl patches based on the statistics of blocks and natural cities; (4) categorize spatio-temporal clusters of long stop points into hotspots and traffic jams; and (5) perform an across-country comparison of hierarchical spatial structures. The overall contribution of this thesis is first to propose the principle of scaling of geographic space as well as the head/tail division rule, which provide a new and quantitative perspective to efficiently reduce the high degree of complexity and effectively solve the issues in urban studies. Several successful applications prove that the scaling of geographic space and the head/tail division rule are inspiring and can in fact be applied as a universal law, in particular, to urban studies and other fields. The data sets that were generated via an intensive geo-computation process are as large as hundreds of gigabytes and will be of great value to further data mining studies.QC 20120301

Abstract:
Pour améliorer les performances des robots sous marins, l'une des approches poursuivie par les roboticiens, appelée biomimétisme, consiste à imiter ou à s'inspirer des systèmes vivants pour concevoir des robots de nouvelle génération. C'est dans ce contexte que s'est récemment déroulé un projet européen nommé ANGELS, dont l'objectif est la réalisation d'un robot bio-inspiré de l'anguille. Ce travail expérimental s'inscrit dans ce projet et est consacré à l'étude de la nage du robot. Les expériences ont été réalisées dans un canal hydraulique conçu pour cette étude. Dans un premier temps, nous avons caractérisé par traitement d'images les allures (i.e. les lois de déformation du corps) adoptées par une anguille nageant soit dans un écoulement uniforme frontal ou dans un courant traversier. Cette étude a donné lieu à l'établissement d'un modèle mathématique corrélatif de la déformation du corps de l'anguille dans ces conditions de nage. Dans un second temps, afin d'étudier les effets de la déformation du corps sur l'écoulement latéral, produit lors de la nage, des expériences par PIV ont été réalisées sur différents modèles de cylindres elliptiques rigides. Ces résultats nous ont permis de mieux comprendre et de valider une approche théorique permettant de calculer la force de propulsion en réponse à la loi de déformation du corps. Enfin, des expériences portant sur la nage anguilliforme dans un écoulement de type allée de von-Kàrmàn ont été réalisées en vue d'étudier les interactions hydrodynamiques et en particulier les mécanismes d'extraction de l'énergie de l'écoulement incident. Ces expériences ont été réalisées avec une anguille et un robot anguilliforme. Les expériences menées sur le robot montrent que pour une même loi de déformation du corps, la force de propulsion générée, en comparaison avec le cas de l'écoulement uniforme, peut sous certaines conditions être augmentée de près de 30 ont, quant à elles, permis de mettre clairement en évidence une modification de l'allure de nage de l'anguille lorsqu'elle est placée dans une allée de von-Kàrmàn. L'analyse qualitative de cette nouvelle allure nous a conduit à proposer un mode particulier d'extraction d'énergie de l'écoulement.

Abstract:
Distributed stream-based applications manage large quantities of data and exhibit unique production and consumption patterns that set them apart from general-purpose applications. This dissertation examines possible ways of creating more efficient memory management schemes. Specifically, it looks at the memory reclamation problem. It takes advantage of special traits of streaming applications to extend the definition of the garbage collection problem for those applications and include not only data items that are not reachable but also items that have no effect on the final outcome of the application. Streaming applications typically fully process only a portion of the data, and resources directed towards the remaining data items (i.e., those that dont affect the final outcome) can be viewed as wasted resources that should be minimized.
Two complementary approaches are suggested:
1. Garbage Identification
2. Adaptive Resource Utilization
Garbage Identification is concerned with an analysis of dynamic data dependencies to infer those items that the application is no longer going to access. Several garbage identification algorithms are examined. Each one of the algorithms uses a set of application properties (possibly distinct from one another) to reduce the memory consumption of the application. The performance of these garbage identification algorithms is compared to the performance of an ideal garbage collector, using a novel logging/post-mortem analyzer. The results indicate that the algorithms that achieve a low memory footprint (close to that of an ideal garbage collector) perform their garbage identification decisions locally; however, they base these decisions on best-effort global information obtained from other components of the distributed application.
The Adaptive Resource Utilization (ARU) algorithm analyzes the dynamic relationships between the production and consumption of data items. It uses this information to infer the capacity of the system to process data items and adjusts data generation accordingly. The ARU algorithm makes local capacity decisions based on best-effort global information. This algorithm is found to be as effective as the most successful garbage identification algorithm in reducing the memory footprint of stream-based applications, thus confirming the observation that using best-effort global information to perform local decisions is fundamental in reducing memory consumption for stream-based applications.

Multimedia applications are the most dominant workload in desktop and mobile computing. Such applications regularly process continuous sequences of data and can be naturally represented under the stream programming domain to take take advantage of domain-specific optimizations. Exploiting characteristics specific to multimedia programs can provide further significant impact on performance for this class of programs. This thesis identifies many multimedia applications that maintain induction variable state, which directly inhibits data parallelism for the program. We demonstrates it is essential to recognize and parallelize filters with induction variable state to enable scalable parallelization. We eliminate such state by introducing a new language construct that automatically returns the current iteration number of a target filter. This thesis also exploits the fact that multimedia applications are tolerant in the accuracy of the program output. We apply a memoization technique that exploits this tolerance and the repetitive nature of multimedia data. We provide a runtime system that automatically tunes the memoization capabilities for performance and output quality. These optimizations are implemented in the StreamIt programmming language. The necessity of parallelizing induction variable state and performance improvements and quality control of our memoization technique is demonstrated by a case study of the MPEG benchmark.

Lai, Farley. "Stream processing optimizations for mobile sensing applications." Diss., University of Iowa, 2017. https://ir.uiowa.edu/etd/5797.
Abstract:
Mobile sensing applications (MSAs) are an emerging class of applications that process continuous sensor data streams to make time-sensitive inferences. Representative application domains range from environmental monitoring, context-aware services to recognition of physical activities and social interactions. Example applications involve city air quality assessment, indoor localization, pedometer and speaker identification. The common application workflow is to read data streams from the sensors (e.g, accelerometers, microphone, GPS), extract statistical features, and then present the inferred high-level events to the user. MSAs in the healthcare domain especially draw a significant amount of attention in recent years because sensor-based data collection and assessment offer finer-granularity, timeliness, and higher accuracy in greater quantity than traditional, labor-intensive, data gathering mechanisms in use today, e.g., surveys methods. The higher fidelity and accuracy of the collected data expose new research opportunities, improve the reliability and accuracy of medical decisions, and empower users to manage personal health more effectively.
Nonetheless, a critical challenge to practical deployment of MSAs in real-world is to effectively manage limited resources of mobile platforms to meet stringent quality of service (QoS) requirements in terms of processing throughput and delay while ensuring long term robustness. To address the challenge, we model MSAs in dataflows as a graph of processing elements that are connected by communication channels. The processing elements may execute in parallel as long as they have sufficient data to process. A key feature of the dataflow model is that it explicitly capture parallelism and data dependencies between processing elements. Based on the graph composition, we first proposed CSense, a stream-processing toolkit for robust and high-rate MSAs. In this work, CSense provide a simple language for developers to describe their sensing flow without the need to deal with system intricacy, such as memory allocation, concurrency control and power management. The results show up to 19X performance difference may be achieved automatically compared with a baseline using the default runtime concurrency and memory management.
Following this direction, we saw the opportunities that MSAs can be significantly improved from the perspective of memory performance and energy efficiency in view of the iterative execution. Therefore, we next focus on optimizing the runtime memory management through compile time analysis. The contribution is a stream compiler that captures the whole program memory behavior to generate an efficient memory layout for runtime access. Experiments show that our memory optimizations reduce memory footprint by as much as 96% while matching or improving the performance of the StreamIt compiler with cache optimizations enabled.
On the other hand, while there is a significant body of work that has focused on optimizing the throughput or latency of processing sensor streams, little to no attention has been given to energy efficiency. We proposed an accurate offline energy prediction model for MSAs that leverages the pipeline structure and iterative execution nature to search for the most energy saving batching configuration w.r.t. a deadline constraint. The developers are expected to visualize the energy delay trade-off in the parameter space without runtime profiling. The evaluation shows the worst-case prediction errors are about 7% and 15% for energy and latency respectively despite variable application workloads.

Abstract:
L'application de Lyashko-Looijenga LL associe à une fonction rationnelle l'ensemble non ordonné de ses valeurs critiques. Nous étudions d'abord cette application sur l'espace des déformations verselles de la singularité An. Nous déterminons le degré de LL sur toutes les strates de cet espace, ainsi que sa multiplicité transverse relative pour toute paire de strates adjacentes. Nous étudions ensuite l'espace des déformations verselles de la singularité Dn et quelques espaces plus généraux de fonctions rationnelles. Nous trouvons le degré de LL sur les strates simples, c'est-à-dire constituées de fonctions n'atteignant chaque valeur critique qu'en un seul point critique. Finalement, nous considérons l'application LL sur une compactification naturelle de l'espace de toutes les fonctions rationnelles de degré n. Nous décrivons explicitement l'anneau de cohomologie de cet espace, Nous montrons que le problème de trouver le degré de LL sur les strates de cet espace est lié à sa théorie de l'intersection. Nous établissons plusieurs relations entre les classes d'homologie déterminées par les strates et en déduisons des résultats combinatoires sur le nombre de revêtements ramifiés de CP1 par CP1. Un autre résultat de la thèse est l'extension de la notion de différentielles de Strebel aux courbes complexes stables. Nous prouvons que les différentielles de Strebel ainsi définies forment une famille continue au-dessus de l'espace des modules M(g,n) des courbes stables de genre g avec n points marquésThe Lyashko-Looijenga map LL assigns to a rational function the unordered set of its critical values. We first study this map on the space of versal deformations of the An singularity. We determine the degree of LL on all strata of this space, as well as the relative transversal multiplicity for each pair of adjacent strata. We then study the space of versal deformations of the Dn singularity and some more general spaces of rational functions. We find the degree of LL on simple strata, i. E. , on strata composed of functions that attain each critical value at a unique critical point. Finally, we consider the LL map on a natural compactification of the space of all rational functions of degree n. We explicitely describe the cohomology ring of this space. We show that the problem of finding the degree of LL on the strata of this space is related to its intersection theory. We establish several relations between the homology classes represented by the strata and deduce combinatorial results on the numbers of ramified coverings of CP1 by CP1. Another result of the thesis is the extension of the notion of Strebel differentials to stable complex curves. We show that the Strebel differentials thus defined form a continuous family over the moduli space M(g,n) of stable curves of genus g with n marked points

Abstract:
La musica e i metodi attraverso i quali essa viene creata, condivisa e riprodotta hanno sempre avuto importanza per le persone. Nonostante esistano una moltitudine di servizi che permettono lo streaming di prodotti finiti, al giorno d'oggi risulta particolarmente difficile riuscire a suonare e creare brani musicali a distanza, in tempo reale. Non vi è alcun servizio che permetta una gestione semplice e funzionante di tale processo. L'obiettivo della ricerca e del progetto qui presentati è quello di fornire un modo intuitivo in cui un qualsiasi utente provvisto di strumento musicale MIDI e di dispositivi ormai largamente diffusi, come uno smartphone o un tablet, possa effettuare una "Jam Session", cioè una sessione in cui suonare in tempo reale insieme ad altre persone collegate in remoto. I concetti che vengono affrontati sono legati al mondo dell'Internet of Things e della Networked Music Performance. Questa ricerca può portare grandi benefici al processo creativo di brani musicali, alle esibizioni "dal vivo" e alla didattica musicale.
Assieme al progetto, viene descritta una implementazione e uno studio di fattibilità. Si vedrà come il sistema proposto possa essere a tutti gli effetti utilizzato ed eventualmente ampliato in futuro.

Abstract:
A Computational Aeroacoustics (CAA) and a novel semi-empirical model is developed for predicting the noise generated by the jet flow through dual stream (coaxial) nozzles, as found in modern turbofan engines. The acoustic source model was developed in a 2D and 3D framework, based on the Lilley's Equations, following the traditional MGBK method from NASA Langley Research Center. The semi-empirical model was based on the Four-Source model from the Institute of Sound and Vibration (ISVR). This suite of methodologies provided a mean of investigating the mechanisms of noise generation and propagation of subsonic coaxial jet flows, as well as the noise prediction at different operating conditions. The work done contributed to the development and improvement of a numerical tool for jet noise prediction of dual-stream exhaust systems, commonly employed in turbofan engines. Such research also subsidies the improvement of semi-empirical methods used in the Center of Reference in Gas Turbine (ITA) for the noise prediction of turbofans in all operating conditions.

Abstract:
L’analyse de flux de données est utilisée dans beaucoup de contexte où la masse des données et/ou le débit auquel elles sont générées, excluent d’autres approches (par exemple le traitement par lots). Le modèle flux fourni des solutions aléatoires et/ou fondées sur des approximations pour calculer des fonctions d’intérêt sur des flux (repartis) de n-uplets, en considérant le pire cas, et en essayant de minimiser l’utilisation des ressources. En particulier, nous nous intéressons à deux problèmes classiques : l’estimation de fréquence et les poids lourds. Un champ d’application moins courant est le traitement de flux qui est d’une certaine façon un champ complémentaire aux modèle flux. Celui-ci fournis des systèmes pour effectuer des calculs génériques sur les flux en temps réel souple, qui passent à l’échèle. Cette dualité nous permet d’appliquer des solutions du modèle flux pour optimiser des systèmes de traitement de flux. Dans cette thèse, nous proposons un nouvel algorithme pour la détection d’éléments surabondants dans des flux repartis, ainsi que deux extensions d’un algorithme classique pour l’estimation des fréquences des items. Nous nous intéressons également à deux problèmes : construire un partitionnement équitable de l’univers des n-uplets par rapport à leurs poids et l’estimation des valeurs de ces n-uplets. Nous utilisons ces algorithmes pour équilibrer et/ou délester la charge dans les systèmes de traitement de fluxNowadays stream analysis is used in many context where the amount of data and/or the rate at which it is generated rules out other approaches (e.g., batch processing). The data streaming model provides randomized and/or approximated solutions to compute specific functions over (distributed) stream(s) of data-items in worst case scenarios, while striving for small resources usage. In particular, we look into two classical and related data streaming problems: frequency estimation and (distributed) heavy hitters. A less common field of application is stream processing which is somehow complementary and more practical, providing efficient and highly scalable frameworks to perform soft real-time generic computation on streams, relying on cloud computing. This duality allows us to apply data streaming solutions to optimize stream processing systems. In this thesis, we provide a novel algorithm to track heavy hitters in distributed streams and two extensions of a well-known algorithm to estimate the frequencies of data items. We also tackle two related problems and their solution: provide even partitioning of the item universe based on their weights and provide an estimation of the values carried by the items of the stream. We then apply these results to both network monitoring and stream processing. In particular, we leverage these solutions to perform load shedding as well as to load balance parallelized operators in stream processing systems

Abstract:
From the advent of association rule mining, it has become one of the most researched areas of data exploration schemes. In recent years, implementing association rule mining methods in extracting rules from a continuous flow of voluminous data, known as Data Stream has generated immense interest due to its emerging applications such as network-traffic analysis, sensor-network data analysis. For such typical kinds of application domains, the facility to process such enormous amount of stream data in a single pass is critical.

Abstract:
The Kalman Filter has been applied to many fields of hydrology, particularly in the area of flood forecasting. This recursive estimation technique is based on a state-space approach which combines model description of a process with data information, and accounts for uncertainties in a hydrologic system. This thesis deals with applications of the Kalman Filter to ARMAX models in the context of streamflow prediction. Implementation of the Kalman Filter requires specification of the noise covariances (Q, R) and initial conditions of the state vector (x₀, P₀). Difficulties arise in streamflow applications because these quantities are often not known.
Forecasting performance of the Kalman Filter is examined using synthetic flow data, generated with chosen values for the initial state vector and the noise covariances. An ARMAX model is cast into state-space form with the coefficients as the state vector. Sensitivity of the flow forecasts to specification of x₀, P₀, Q, R, (which may be different from the generation values) is examined. The filter's forecasting performance is mainly affected by the combined specification of Q and R. When both noise covariances are unknown, they should be specified relatively large in order to achieve a reasonable forecasting performance. Specififying Q too small and R too large should be avoided as it results in poor flow forecasts. The filter's performance is also examined using actual flow data from a large river, whose behavior changes slowly with time. Three simple ARMAX models are used for this investigation. Although there are different ways of writing the ARMAX model in state-space form, it is found that the best forecasting scheme is to model the ARMAX coefficients as the state vector. Under this formulation, the Kalman Filter is used to give recursive estimates of the coefficients. Hence flow predictions can be revised at each time step with the latest state estimate. This formulation also has the feature that initial values of the ARMAX coefficients need not be known accurately.
The noise variances of each of the three models are estimated by the method of maximum likelihood, whereby the likelihood function is evaluated in terms of the innovations. Analyses of flow data for the stations considered in this thesis, indicate that the variance of the measurement error is proportional to the square of the flow.
In practice, flow predictions several time steps in advance are often required. For autoregressive processes, this involves unknown elements in the system matrix H of the Kalman model. The Kalman algorithm underestimates the variance of the forecast error if H and x are both unknown. For the AR(1) model, a general expression for the mean square error of the forecast is developed. It is shown that the formula reduces to the Kalman equation for the case where the system matrix is known. The importance of this formula is realized in forecasting situations where management decisions depend on the reliability of flow predictions, reflected by their mean square errors.Applied Science, Faculty of

Abstract:
Current Audio-Video (A-V) players are limited to pausing, resuming, selecting and viewing a single video stream of a live broadcast event that is orchestrated by a professional director. The main objective of this research is to investigate how to create a new custom-built interactive A V player that enables viewers to personalise their own orchestrated views of live events from multiple simultaneous camera streams, via interacting with tracked moving objects, being able to zoom in and out of targeted objects, and being able to switch views based upon detected incidents in specific camera views. This involves research and development of a personalisation framework to create and maintain user profiles that are acquired implicitly and explicitly and modelling how this framework supports an evaluation of the effectiveness and usability of personalisation. Personalisation is considered from both an application oriented and a quality supervision oriented perspective within the proposed framework. Personalisation models can be individually or collaboratively linked with specific personalisation usage scenarios. The quality of different personalised interaction in terms of explicit evaluative metrics such as scalability and consistency can be monitored and measured using specific evaluation mechanisms.

Abstract:
In this day and age, with highly available and fast networks, many tasks are being performed remotely. However, certain tasks cannot be flawlessly executed remotely, for instance, the tasks performed by professional drivers. Their jobs demand a lot of visual cues, fast actions, and low response times, which is difficult in particular when task execution is performed wirelessly. With the release of 5G, which promises to deliver reliable and rapid response times with URLLC, high bitrates with eMBB, and supports a massive number of devices with mMTC, many companies and researchers are trying to investigate if 5G is an enabler for wireless control of commercial vehicles. This thesis first examines the latency requirements for remote control operations, and then see how 5G can meet those requirements. In this respect, the thesis discovers the latency thresholds without affecting the control performance in a scenario with users operating a small robot. Then, various tests were performed using a trial 5G system to evaluate its performance in terms of latency, video quality, bandwidth, and signal strength. In controlling robot experiments, the results showed that the highest acceptable cycle latency, both for accurate maneuvering and satisfying operator experience, is around 154ms. These results were then used as a benchmark in the tests conducted using a 4G public network and a single-cell 5G network. These tests revealed that 5G could deliver lower latencies, higher bitrates, and similar video quality when compared to 4G. However, it was difficult to retain good signal quality over 5G, especially when roaming in non-line-of-sight propagation areas. This behavior is as expected due to the terminal’s association with a single 5G base station, which can be easily mitigated with denser deployments.

In this thesis, the wireless sensor network is used to develop a streetlight monitoring system. Zigbee wireless sensor module was chosen to operate the system to monitor streetlights’ functioning so that the operator of the supervisory system will be able to detect the streetlights that are malfunctioned promptly. The information of which streetlight is malfunctioned and where it is located will be displayed on server’s monitor via Google Earth online map, which allows the system operator to inform maintenance workers through phone calls or text messages. In comparison to the traditional way which relies on passengers who spot the malfunctioned streetlight and inform the maintenance unit actively, this system is much faster and effective. In this system, three conditions are monitored: streetlight functioning during daytime and at night, as well as the module itself. Under the monitoring, defined malfunctioned situations are (1) streetlights on during daytime when the sunlight is strong enough, (2) streetlights are still off at night or when the surroundings are getting dark during daytime, and (3) power disconnection or breakdown in transmission of the Zigbee wireless sensor network. The proposed streetlight monitoring system has two modes—automatic and manual. The automatic functions inform the server streetlights’ condition, while the manual is designed to open the lights under two conditions. At first, whenever the natural lights are not strong enough in daytime, it is turn on to ensure the passengers’ safety. Secondly, to turn off the light whenever there is ample lighting provided by the surroundings during the night to save energy. Keywords：Wireless sensor network, streetlight, Zigbee, Google Earth.

Augmented reality is a technology that over the past twenty years has had a substantial evolution, both in techniques and in products, such as Google Glass and Pokémon GO, affecting several areas and progressively becoming a part of our lives. One of the areas that has had several interventions with augmented reality is art, on which this technology is being integrated into museums and art galleries as a supplementary source of information. The focus of this project is street art, an artistic field in which artists create their artworks in public locations, usually outdoors. However, the particularity of this field is that many of the created artworks remain unknown. Unlike museums or galleries, which present the information about the exhibits in signs and leaflets, street artworks only have the artist’s signature associated, which sometimes is not clear. This dissertation proposes the creation of an augmented reality application for mobile devices, where users not only can augment artwork to see information about it but also to see it in motion, thus providing a different and enjoyable experience. The process of creating and developing an augmented reality system in a real context is explored, as well as the creative methods for animating the murals. This dissertation results in an application that allows users to access quickly and easily information about street artworks, as well as guiding them to more pieces located nearby. Consequently, the user learns more about street art and discovers new artworks that could likely pass unseen.

This thesis mainly applies the modular design concept and the genetic algorithm to design a streetlamp based on the light emitting diode (LED) light source. The design approach is as the following: (1) Multiple LEDs are first arranged and combined to form a light-source module; (2) Next the required optic, Fresnel lens, of the module is designed based on the optical characteristics of LEDs; (3) Then, the optimal value of the lens’s groove angle is found by using the genetic algorithm incorporated with the link of Matlab and TracePro programs; (4) Finally, a highly efficient and evenly illuminant LED streetlamp is designed based on the regulation of legal streetlamp and the designed light-source modules. The simulated result shows that the averaged illuminance of the designed LED streetlamp in this thesis is34.66luces based on the nine-point measurement. This value satisfies the requested illuminant standard of 30 luces on a city main street, and the uniformity (Minimum illuminance/Averaged illuminance) of (29:35) also satisfies the legal value (>1.3). In addition, the proposed design approach of LED streetlamps is not only simple, high efficient, time-saving in design, and also can obtain a luminaire with uniform luminance. For the design and development of LED illuminant lamps, this thesis provides another selection of design approach and technology.

Nowadays, cosmetics are mainly made of artificial chemical materials. Although there is no clear research indicates the impact of these materials in environment, they actually do not have the concept of sustainable use, and the dangers that may be caused to health are also unknown. Therefore, it becomes a trend to add natural extracts in cosmetics. In this study, we chose ZL which are often plants as sidewalk trees to investigate the mechanism of anti oxidation, whitening, anti inflammation, prevention of photoaging and DNA repair by ZLSE, ZLSW,ZLLE, and ZLLW, respectively. Results show that the ZLSE, ZLSW, ZLLE and ZLLW have great ability of DPPH. and ABTS.+ free radical scavenging. In the tests of reducing power and ferrous iron chelating have significant efficacy. In the lipid peroxidation test, the effects of ZLSE, ZLSW, ZLLE and ZLLW were similar to or even exceeded by Trolox. However, there was no significant difference between ZLSE, ZLSW, ZLLE and ZLLW in total phenols, total flavonoids, total anthocyanins and total polysaccharides which means all of the above have great ability(potentiality) of an anti oxidation. In addition, it was found that ZLSE, ZLLE and ZLLW had a tendency to promote melanin production in the experiments of inhibiting tyrosinase. Moreover, since ZLSE and ZLLE were shown to be toxic in cell viability assays, subsequent experiments were performed with ZLSW and ZLLW. In the intracellular antioxidant assay, ZLSW and ZLLW could effectively inhibit the production of reactive oxygen species (ROS) and superoxide (O2.--) in HaCaT cells, and increased the content of glutathione (GSH). The performance of superoxide dismutase (SOD), glutathione perxidase (GPx) and catalase also showed an increasing trend. Whitening test was conducted on B16F10 cells, and the results showed that ZLSW and ZLLW could enhance melanin production, and improve the performance of melanocyte inducing transcription factor (MITF), melanocortin--1 receptor (MC1R), tyrosinase, and tyrosinase--related protein--1 (TRP--1). HaCaT cells were used to evaluate the anti--inflammatory efficacy, and it was found that ZLSW and ZLLW could both decrease the performance of tumor necrosis factor--α (TNF--α), interleukin--1β (IL--1β) and IL--6, and reduced the activation of the mitogen--activated protein kinase (MAPK) family. The photoaging prevention tests confirmed that ZLSW and ZLLW had the ability of reducing matrix metalloproteinase (MMPs) and increase collagen synthesis by 3T3L1 cells. HaCaT cells were used to confirm that ZLSW and ZLLW could reduce the photochemical products induced by UVB irradiation, such as cyclobutane pyrimidine dimers (CPDs) and 6--4photoproducts (6--4PPs), and thus promoted DNA repair. Moreover, ZLSW and ZLLW could repair DNA damage induced by UVB through regulating relevant proteins of nucleotide excision repair (NER) system. According to the present study, ZL water extracts has the effect on anti--oxidation, anti--inflammation, anti--photoaging, repair and induce melanin production. ZL water extracts will be a promising material in the future if it can be applied to the development of cosmetic raw materials, and it is more suitable for the hair related commodities in particular because of its performance on inducing melanin production.

The warning message that planet earth is about to be depleted of its precious resources gave birth to global industrial pursuit of “sustainable development.” “Sustainable design” that effectively integrates energies and reduces environmental destruction will be the primary development strategy to keep up with the green environment movement and intensify global competitiveness. For major urban scenic arteries, his study integrates scattered urban information facilities, such as street lights, traffic lights, road signs, traffic signs and pedestrian count-down lights, in a modularized street-light set through flexible approaches. Thereby, it beautifies the views of a city and creates urban landscapes that carry local features of a particular metropolitan area. Based on the design concept of “sustainable development,” this study first explores various dimensions including beautification of shared-pole street lights, regional landscapes, and legal provisions pertinent to installation of street lights. It identifies design requirements and concerns of shared-pole street lights as basis and reference for design of shared-pole street lights. Two types of shared-pole street lights of two different creative concepts are developed accordingly for comparison, analysis and individual production cost estimate in order to understand whether the shared-pole street light designed for this study can better meet the requirement of current major urban arteries and serve as design reference for future designers of shared-pole street lights.

Compared with traditional lighting sources, the light emitting diode (LED) have features of smaller size, longer lifetime, higher brightness, harder to be broken and free of mercury. They are suitable for energy-saving lighting applications nowadays. Usually, commercial LED drivers for street lighting applications are three-stage or two-stage circuit topology. The disadvantages of conventional LED drivers are the large volume, large numbers of circuit components, and limited circuit efficiency due to multi-stage power conversions. Therefore, this thesis presents a single-stage LED driver for street lighting applications with high power factor, which is combined an improved bridgeless converter with a half-bridge LLC resonant converter. The features of the proposed LED driver are reduced numbers of circuit components, cost-effectiveness, and high efficiency. In addition, the inductor of the improved bridgeless converter is designed to be operated at discontinuous conduction mode (DCM) in order to naturally obtain high power factor and low total harmonics distortion of input current (THD). Moreover, the half-bridgeless LLC resonant converter has soft-switching function to lower the switching losses resulting in high circuit efficiency. Besides, descriptions and analysis of the proposed LED street lighting driver are included in this thesis and a prototype driver for providing with a 144W LED street lighting lamp has been implemented and testified. Finally, experimental results are compared with the IsSpice-based simulated ones in order to verify the functionality of the presented circuit.

Public art and street furniture are accumulations of a culture and the shortcut for people to interact with the environment. They play an important role in the environment; it is like having icing on the cake rather than gilding the lily. They also represent a sense of well-being and beauty of life within environment space. Since the change of the society and the increase of population, quality of urban life is on high demand as well as urban landscaping. The government have also put large effort on the planning and design of the urban landscaping. Other than having easy accesses and being eco-friendly in urban areas, the development in social art is essential through display of public art and street furniture in a way to influence the total environment, to promote humanity accomplishment, and to upgrade the living standard of cities. This research will discuss the application of public art and street furniture in urban landscape. The principles of urban landscaping design are generalized through investigating existed literature, information, and analysis of national and international artworks which provide a fundamental theory of public art and street furniture planing and design. Through further researching and analyzing actual cases, a deeper understanding of the combination of public art and street furniture and urban landscaping can be developed.

The capacitated arc routing problem (CARP) is a special routing problem which has a variety of practical applications, such as snow plowing, street sweeping, winter gritting, household waste collection, The classical CARP is defined on an undirected graph with a set of edges. Each edge has a routing cost and a demand. The edges with positive demand make up the subset of the required edges. A set of identical vehicles with limited capacity is available. Each required edge has to be served exactly once by one vehicle. Each route must start and end at the depot. The objective of CARP is to find a set of vehicle routes to minimize the total cost. Due to that CARP is a NP-hard problem, this research intends to present an Ant Colony Optimization (ACO) meta-heuristic to solve the CARP. The result is further improved by a local search with path-relinking for ACO. ACO is tested on eight groups of benchmark instances from the literature. The computational results show that ACO is effective to solve the CARP and its performance is highly competitive. ACO reaches 90% best known solutions in all instances. In the practical application, this research applies the proposed ACO to solve the street cleaning planning problem with intermediate refill points in Kaohsiung city. The results are presented in a road network on the Google Map. The results show that the travel distance of street cleaning can be reduced by arranging and planning the new routes under our ACO algorithm. Finally, we hope that this research will add time windows and fuel costs constraints in the future.

Street lights provide the lighting for people. The street lights are opened in the evening, and closed in the morning. According to the location and time of the person, we find that street lights need not to maintain in a long time to open. It will cause a huge waste of electricity. In our thesis, we established a smart street light system. The main aim of the smart street light systems is automatic to turn on and off depending on the light. The smart street light system also can detect pedestrians and vehicles approaching, they will automatically turn on, and turn off when leaving. The system can also provide the information of the monitor due to the wide distribution. The street light architecture is divided into three parts: the device, the server, and the client. The services of the device include the temperature and humidity detection, the rainfall detection, the noise detection, the air quality detection, the brightness detection. The server will provide the hardware to store the data and execute the programs. The client analyzes the collected information of the database to display a dynamic graphical webpage on the website. In our built smart street lighting system, we can monitor and gather the data of detections. It also has the expansible characteristics. If we have any new sensors in the future, we can combine easily into this system. Our system can be a basic structure to build the simulated smart city.

Abstract:
Conventional street design has given drivers priority over the street. This has resulted in overall declination of the public realm. This study explored the topic of shared space, defined as an approach in which the street is designed in a way that pedestrians, drivers and other street users have equal entitlement and priority throughout the entire space. The research draws upon the literature on shared space; and case studies comprised of secondary source descriptions, key-informant interviews and on-site observation. Ensuing findings suggested that vehicles were more willing to share the streetscape with pedestrians when vehicular speeds were reduced and there was integration between sidewalk and roadway. These findings led to development of a set of principles that informed recommendations for the conceptual redesign of Toronto’s Downtown Yonge Street as a shared space.

The repairing and re-using engineering of the BapraiLiaw Street is an important municipal construction for the design and use of related visual translation code. The purpose of the engineering is to found historical street on education world and to liven historical street by educational activities. It is expected to construct a visual system through planning, collecting, investigating, researching, and displaying education and cultural recourses. The visual system could help the Center of Native Taiwanese Studies improve their self-identification and make people realize this job. The organization identification and space design are planned to construct the culture code on the performance of wording, image identification, and the concept of composing in order to conform the educational atmosphere and develop the identification system model. Chapter One talks about the background and motive of the image code of BapraiLiaw，the typical code of the local place，the use of visual code，and the research of sigals. Chapter Two focus on the documents about the space design of the local community，historical buildings and the reuse of the old streets in BapraiLiaw ，the image of the cultural code，identity system of the signal image，and the design & visual plan of the community assets. Chapter Three mentions designing the research of the creation，places and targets and its theory. Chapter Four shows the start of visual analysis，procedures，creative inspiration，and the organization identification and space design . Chapter Five is the presentation of the work. Chapter Six is the Conclution and suggestion of the research.
