▼ Integrated robust planning systems that cover all levels of SC hierarchy have become increasingly important. Strategic, tactical, and operational SC plans should not be generated in isolation to avoid infeasible and conflicting decisions. On the other hand, enterprise planning systems contain over millions of records that are processed in each planning iteration. In such enterprises, the ability to generate robust plans is vital to their success because such plans can save the enterprise resources that may otherwise have to be reserved for likely SC plan changes. A robust SC plan is valid in all circumstances and does not need many corrections in the case of interruption, error, or disturbance. Such a reliable plan is proactive as well as reactive. Proactivity can be achieved by forecasting the future events and taking them into account in planning. Reactivity is a matter of agility, the capability of keeping track of system behaviour and capturing alarming signals from its environment, and the ability to respond quickly to the occurrence of an unforeseen event. Modeling such a system behaviour and providing solutions after such an event is extremely important for a SC.
This study focuses on integrated supply chain planning with stochastic dynamic considerations. An integrated tactical-operational model is developed and then segregated into two sub-models which are solved iteratively. A SC is a stochastic dynamic system whose state changes over time often in an unpredictable manner. As a result, the customer demand is treated as an uncertain parameter and is handled by exploiting scenario-based stochastic programming. The increase in the number of scenarios makes it difficult to obtain quick and good solutions. As such, a Branch and Fix algorithm is developed to segregate the stochastic model into isolated islands so as to make the computationally intractable problem solvable. However not all the practitioners, planners, and managers are risk neutral. Some of them may be concerned about the risky extreme scenarios. In view of this, the robust optimization approach is also adopted in this thesis. Both the solution robustness and model robustness are taken into account in the tactical model. Futhermore, the dynamic behaviour of a SC system is handled with the concept of Model Predictive Control (MPC).

▼ This thesis presents a new general purpose power
system simulation technique based on
dynamic phasors and conventional power
system simulation methods. The method developed in this work converts time-domain circuits to equivalent
dynamic phasor representations. These
dynamic phasor equivalents are then simulated using nodal analysis and numerical integrator substitution. Simple linear circuit models are presented first in order to demonstrate that the new method is capable of accurately simulating small systems. The method developed in this work is then expanded to include control systems, power electronic converters, and synchronous machines. Visual comparisons with simulation results obtained using time-domain electromagnetic transient simulators demonstrate that the new
dynamic phasor-based technique is capable of accurately simulating power
system components.

▼ Combustion technology has been used in many areas today, such as in the synthesis of advanced materials, power generation and the production of engines. Combustion has been studied for a long time and many models have been developed to describe such combustion processes. However, most of those models focused on one-step combustion reaction schemes, with few considering more complex combustion reaction schemes.Our research interest is flame propagation in a two-stage reaction under adiabatic conditions in one-dimension. Specifically, we consider the following sequential reaction:A – >B+Q1 – >P+Q2.Here both reactions are assumed to proceed at temperature-dependent rates. The first reaction transforms the fuel A into the intermediate product B and heat Q1, while the second reaction transforms the intermediate species B into the final product P and heat Q2. An exothermic-endothermic scheme is considered here, so that Q1>0 (exothermic) and Q2<0 (endothermic). The above reaction scheme has direct relevance to blast furnace chemistry, in particular to the process of iron ore reduction in iron ore/coal composites. In our study, the properties of travelling combustion waves were investigated numerically by solving a
system of nonlinear differential equations
subject to appropriate boundary conditions. We study the wave speed and extinction limits of the combustion wave. Throughout our numerical investigation, we have employed independent methods to check the accuracy of the numerical solutions to ensure that the dynamics of the
system is observed rather than numerical artefacts.Instability in combustion waves has been detected by both experiments and numerical simulations of combustion models. In this thesis, we also present results from our preliminary investigation of oscillation and chaotic combustion profiles. The objective is to investigate how these properties vary as parameter values change. The parameters of interest include those describing the rates and activation energies of the exothermic and endothermic reactions, the ratio of thermal to mass diffusivities of the fuel and intermediates. The transitions from stable to unstable planar wave solutions as well as various bifurcations have been found and numerically analysed.

▼ This dissertation is devoted to the development of distributed algorithms, with which nodes in a large decentralized network can accomplish tasks that are seemingly difficult without an omniscient central node. The tasks include estimating the graph spectrum, from which each node can draw its own conclusion about the network structure, computing the eigenvector centrality, from which every node can judge its own importance in the network, and solving a
system of linear equations whose data are scattered across the network or discovering that no solution exists. The ability to perform these tasks enhances the capability of existing and emerging networks such as smart power grids, social networks, and ad hoc sensor networks, potentially allowing them to function in ways that are not previously thought to be possible.
We begin with the design of a novel, two-stage distributed algorithm that enables nodes in an undirected and connected graph to jointly estimate the spectrum of a matrix associated with the graph, which includes the adjacency and Laplacian matrices as special cases. In the first stage, the algorithm uses a discrete-time linear iteration and the Cayley-Hamilton theorem to convert the problem into one of solving linear equations, where each equation is known to a node. In the second stage, if the nodes happen to know that said matrix is cyclic, the algorithm uses a Lyapunov approach to asymptotically solve the equations with an exponential rate of convergence. Otherwise, it uses a random perturbation approach and a structural controllability result to approximately solve the equations with an error that can be made small.
We then consider the fundamental problem of cooperatively solving a general
system of linear equations over a network, for which a continuous-time distributed algorithm is devised. We show that the algorithm enables the nodes to asymptotically agree on a solution when there are infinitely many solutions, determine the solution when there is exactly one, and detect that no solution exists when there are none. We also establish that the algorithm is globally exponentially convergent, derive an explicit lower bound on its convergence rate that it can do no worse than, and prove that the larger the network's algebraic connectivity, or the further away from being singular the
system of equations, the larger this lower bound.
Finally, we address the open question of whether it is possible to calculate eigenvector centrality over a network. We provide an affirmative answer by presenting a class of continuous-time distributed algorithms and an asynchronous gossip algorithm, which allow every node i in a graph to compute the ith entry of the Perron-Frobenius eigenvector of a symmetric, Metzler, and irreducible matrix induced by the graph, as well as the corresponding eigenvalue, when node i knows only row i of the matrix. We show that each continuous-time distributed algorithm is a nonlinear networked dynamical
system with a skew-symmetric structure, whose state is guaranteed to…

based on energy storage units suffer from limitations such as need
of large and costly energy storage units maintenance problems
associated with the storage units and higher weight per kVA rating

▼ Mobile phones have been completely changing the way people think and behave, making our lives convenient. At the same time, this accelerated growth has brought with it unprecedented new threats related to user privacy. A myriad of apps in Android phones are handling various user data. However, each app developer has the principle responsibility to protect them because the Android framework lacks direct support for them. This is not good news, because developers have varying levels of secure coding practice, and the resulting apps may inadvertently misuse of sensitive data of users.
In this thesis, I will present my studies with various Android apps and the Android framework to understand the misuse of secrets in the mobile environment. To assist my work, I have used various analysis techniques and developed a
dynamic analysis framework to perform systematic analyses of Android apps. This dissertation describes approaches and tools I have developed, my findings on how sensitive data is misused, and mitigation to address found security problems.
Our research has had a significant practical impact and helped to mitigate the misuse of secrets in the mobile ecosystem. Specifically, I designed a memory analysis framework that provides physical and logical memory dumping, along with a high degree of automation of experiments. We have discovered that Android keeps TLS master secret live in memory for an unnecessarily long period of time, posing a threat to all Android applications built on standard HTTPS libraries. I found modest changes to Android codebase could mitigate these issues, and reported to Google. Also, our comprehensive analysis of variety of apps revealed that user passwords can survive in a variety of locations for an extended period of time, including UI widgets where users enter their passwords, apps that retain passwords
rather than exchange them for tokens, old copies not yet reused by garbage collectors, keyboard apps, password management apps, and even the lockscreen
system service. I have developed solutions that fix these problems and assist apps to follow more secure practices. Lastly, I will present FlowPass, an efficient and informative
dynamic taint tracking
system that I developed. FlowPass found 13 previously unknown security bugs in popular apps that have each been installed more than one million times. I have reported these misuses to the
app vendors, and most have fixed the bugs shortly afterward.

Along with the diminishing supplies of fossil fuels, the continually increasing price of oil, and the deterioration of the environment as an effect of fossil fueled vehicles, the world now focuses its attention on green energy and vehicle hybridization. This has given rise to many alternatives in internal combustion engine vehicle hybridization such as the parallel and series hybrids, as well as plug-in hybrid electric vehicles. This paper proposes a new method of hybridization which allows ICE vehicles to be retrofitted to take advantage of regenerative braking and acceleration assistance. The conjoined automotive regenerative braking system is a small trailer like device that can be attached via trailer hitch to the ICE vehicle in order to create a pseudo parallel hybrid.
The CARB will be connected to the trailer hitch of the ICE vehicle through a series elastic element in order to filter impulse shock loads as well as provide stability and robustness in force control. This thesis explains the dynamic modeling of the system as well as the response of the system to varying control schemes.
Firstly, the system was analyzed analytically as a Series Elastic Actuator. The system model is very simple and a PD force controller is implemented to regulate the force in the spring connecting the CARB and the Vehicle. The closed loop transfer function is determined and the step response of the system was analyzed to determine that the closed loop natural frequency of the system needed to be above 100Hz in order for the transients in the response to die out within half of a second.
Secondly, a simulink model of the system was created. A linear damper is added in parallel with the series elastic element between the vehicle and the CARB. The system input is a feed forward desired force for the vehicle determined from the Federal Urban Driving Schedule and the mass of the vehicle. A proportion of this feed forward desired force of the car is used as the desired force from the CARB. A PID controller regulates the torque of the CARB to minimize the force error between the desired force and the load force. The control parameters for this load force control scheme are determined using the signal constraint block in simulink and are determined for a variety of linear spring constants and linear damping constants. The velocity error of the system velocity response versus FUDS is less than 0.3 m/s for any simulation, and the load force error was limited to less than 150 N. The power used by the vehicle was shown to be significantly lessened by the addition of the CARB.
Thirdly a more detailed Simulink model was created using the Simscape toolbox which allowed for highly detailed simulated physical entities, such as drivelines, inertias, electronics, etc. This system uses a battery model and DC/DC converter which is connected to a 50kW PMSM to simulate the electronics of the CARB, The longitudinal and tire dynamics of the car and of the system are accounted for. A model of an ICE was used to…

▼ I begin with a brief introduction to
dynamic systems, the identification of
system parameters from records of input and output, and also wave energy converters which provide case studies to motivate the research. The
dynamic systems discussed are categorized as linear or nonlinear
dynamic systems. I present brief reviews of strategies for identification of
dynamic systems which cover the history and also the areas of applications. The discretization of differential equations for
dynamic systems is a recurrent theme and I consider forward, backward and central differences in detail for linear systems. The estimation techniques discussed are the principle of least squares, the Kalman filter and spectral analysis. Several
system identification techniques for nonlinear
dynamic systems in the time domain and in the frequency domain are presented and compared. The main focus of the thesis is estimation methods based on wavelets. I present some introduction to the wavelet transforms, which cover both continuous and discrete wavelet transforms. Wavelet methods for
system identification of linear and nonlinear
dynamic systems are discussed. Throughout this research, I have published four research articles guided by my supervisors. The first article discusses the wavelet based technique for linear
system, and the technique was compared to the spectral analysis technique. The second article compare two types of wave energy converters, where the heaving buoy wave energy converter (HBWEC) is modelled as a linear
system and the oscillating flap wave energy converter (OFWEC) as a nonlinear
system. The frequency domain technique for
system identification of nonlinear
dynamic systems have been applied on the OFWEC model. Unscented Kalman filter have been discussed in the third article where the nonlinear OFWEC
system have been used as the case study. A wavelet approach for nonlinear
system identification has been discussed in the fourth article together with the probing technique. The probing technique was used to find the generalized frequency response functions of the nonlinear
dynamic systems based on the nonlinear autoregressive with exogenous input (ARX) model. Both technique were compared for two weakly nonlinear oscillators, the Duffing and the Van der Pol. Once again, we selected the OFWEC
system as a case study.

▼ Mines in general, make use of compressed air systems for daily operational activities. Compressed air on mines is traditionally distributed in two typical fashions. Firstly, direct pipe feed systems for single shafts or compressed air ring networks where multiple shafts are supplied with compressed air from an integral system. These compressed air networks make use of number compressors feeding the ring from various locations in the network. While mines have sophisticated control systems to control these compressors they are not dynamic.
Compressors are selected on static priorities for a chosen time period of the day. While this is acceptable for some days it is not always the ideal solution. The compressed air demand of the ring is dynamic and it is difficult to estimate the future need of the system. The Dynamic Compressor Selector (DCS) is described as a solution to this problem.
DCS is a computer based control system featuring a Graphical User Interface (GUI). The aim of DCS is to dynamically calculate a control pressure set-point, given the demand for compressed air as well as choose the optimal compressors to supply the given compressed air. This will reduce the power requirement of the compressed air ring as well as reduce compressor cycling.
DCS was implemented and tested on a single mine compressed air system. Achieved results were 1.8 MW in electricity savings as well as the added benefit of reduced cycling. This saving results in a cost saving of R3.7 million per annum. The problems and shortfalls of the system are also discussed as well as possible future directions for moving forward.

▼ Double Skin Facades (DSF) have been studied
extensively in the past for different aspects such as energy and
thermal performance, daylight, acoustics, use as noise barriers,
aesthetics etc. A review of the current state and energy
performance issues of DSF’s are being addressed and mostly
regarding their impact on the building’s performance. Moreover, the
experimental proposal provides a solution to enhance their
efficiency. In order to achieve this goal a
dynamic airflow control
system was proposed in the cavity. The effect of this
system and
its outcomes were examined in energy simulation software. The
proposed
system offers the flexibility to transform a DSF between
the four basic types: multi-story, corridor, shaft box, and window
box. The results were compared among the types and a single skin
façade
system. This transformation allows control of the airflow in
the cavity, and increases or decreases the air velocity/air volume.
The study was made for a climate in each of the cities of: Los
Angeles, New York and Houston. The outcomes identified which facade
typology performs better for which climate, time period (day,
season, year etc.); what the adopting transformation pattern should
be for each location, the time period that contributes to the
energy savings; and finally identified the configurations that
should be avoided in every case. Depending on the climate the
energy savings could be up to 4% for the hottest day and up to
4.32% for the coldest day during a 24h cycle.

▼ Although the operations of enterprise includes four perspectives â finance, customer, internal business processes, learning and growth, the content of each perspective can be further divided into many subjects according to the different characteristic of each enterprise or business field. Among each perspective, they all have causal relationship directly or indirectly. Very often, the other perspectives will be impacted when the strategy or performance of one perspective has been changed, and the final overall performance of enterprise will also be affected via this kind of relationship. Because the relationship among these perspectives is complicated and the problem of time delay is serious, it is difficult for a manager to make correct decisions in this complicated operation
system. Once the wrong strategy is taken, the growth of enterprise will be postponed, or even worse, the enterprise will be out of business by the potential risk that caused by the wrong strategy. For instance, the magic development stories of Wonder Techs and People Express are both very typical examples.
This research takes A Corporation as the object of case study. Through the collection and study of domestic and foreign relative literature, paper and theses, this case study will help the object company find out the opportunity and its orientation on the present and future market environment by STEP analyzing, inspect the companyâs competition and threat by Michael E. Porterâs Five Basic Competitive Forces Analysis, and survey the strength, weakness, opportunity and threat of the company on the market by SWOT method. And finally, the causal relationship diagram of the enterprise operations can be drawn by
system thinking methodology with the four-perspective framework of balanced scorecard from the overall view of enterprise. The analysis of this causal relationship feedback diagram will check the influence of the whole enterpriseâs operation
system by all kinds of operation activities, and even, can set up the enterpriseâs
Dynamic Strategy Map based on this study.
The
Dynamic Strategy Map will help the manager analyze the operation strategy through the angle of the whole
system operations to avoid just emphasizing on the short-term performance and neglecting the necessary of the long-term fundamental measures required for running the enterprise forever. Moreover, it can also assist the manager to pursue the high leverage point from the causal feedback diagram to be the key performance indicator for improving the enterpriseâs operation quality and enhancing its competitiveness, and to allocate the limited resources on the most suitable places to create best benefit.
This case study takes the present condition of A Corporation as the research scope. Restricted by companyâs specific characteristic and present operation condition, the findings of this research cannot be applied to the other enterprises directly. But by comparing with the similar operation activities of the other enterprise or group, the causal relationship feedback among these…

▼ Diversas aplicações executadas em ambientes de cluster necessitam de uma área de armazenamento permanente com alta capacidade e que forneça uma visão homogênea dos dados entre todos os nós. Esta área compartilhada é comumente implementada através de um sistema de arquivos distribuído, permitindo o acesso através da abstração mais comum para gerenciamento de dados. A disparidade entre poder de processamento e desempenho de dispositivos de armazenamento atuais, no entanto, torna tais sistemas um ponto crítico ao desempenho de aplicações paralelas que lidam com grandes volumes de dados. Ambientes de cluster podem apresentar execução concorrente de aplicações em conjuntos independentes de máquinas. Desta forma, uma grande quantidade de clientes com características distintas farão acessos ao sistema de arquivos compartilhado. Em tais casos, o dimensionamento do sistema de armazenamento distribuído nem sempre poderá prover o desempenho necessário à execução das aplicações com os recursos inicialmente a ele destinados. O presente trabalho propõe uma estratégia de reconfiguração dinâmica para o sistema de arquivos dNFSp. Esta estratégia leva em consideração o comportamento temporal presente em aplicações paralelas para inserir servidores de dados exclusivos a aplicações com alta demanda de I/O. Com a utilização de servidores exclusivos, torna-se possível isolar aplicações com comportamentos que causam grande perda de desempenho no sistema como um todo. Foi desenvolvida uma ferramenta de monitoramento do desempenho junto aos servidores do dNFSp, de forma a solicitar novos servidores apenas quando a interação das fases de I/O das aplicações em execução interferirem no desempenho do sistema. Esses novos servidores são solicitados para um sistema escalonador de recursos para cluster, de forma a utilizar nós livres para o armazenamento de dados. Os resultados mostram que a estratégia proposta é capaz de detectar a saturação do sistema de armazenamento e iniciar os servidores exclusivos, levando a um ganho de desempenho para as aplicações em execução. A reconfiguração dinâmica também mostrou-se capaz de evitar baixos desempenhos causados pela interação dos períodos de inatividade de aplicações temporais e pela utilização de diversos processos de I/O em um único nó.
Several applications executed in cluster environments need a shared storage area with high capacity and a homogeneous view of the stored data to all processing nodes. This area is commonly implemented as a distributed file system, allowing the access to data through the well-known file abstraction. The great gap in performance of processors and storage devices, on the other hand, makes such system a critical point to the performance of parallel applications. A common trait of large cluster environments is the concurrent execution of applications. In this scenario, many clients with distinct behaviors will compete to access the shared storage system. The number of I/O resources originally dedicated to this shared storage may provide unsatisfactory performance to the…

▼ Flexible ac transmission system (FACTS) controllers offer new opportunities to better control power systems, and can address some of the critical challenges faced by the grid, especially in the context of smart grids. Furthermore, the smartening of distribution systems with distributed generation, storage devices, and intelligent loads have created challenges for the operation of distribution feeders, which can be addressed adequately with power-electronics based controllers and FACTS controllers for distribution systems. However, the capital intensive nature of these controllers is a major obstacle for a wide application of this technology in power systems. A cost effective FACTS controller has been introduced in the literature, which yields operating characteristics similar to those of the versatile Unified Power Flow Controller (UPFC). This device consists of converters as well as passive components, and is referred to as the Hybrid Power Flow Controller (HPFC). The study of the HPFC and its performance in electric power systems requires adequate and relevant models representing the device behavior according to the intended studies, such as steady state or time-domain dynamic analyses; moreover, the benefits of an HPFC are determined by its limits and operating constraints. Therefore, static and dynamic models of the HPFC for transmission and distribution system applications are proposed and studied in this work.
First, steady-state models of the HPFC for power flow and optimal power flow (OPF) studies are proposed in this work, considering its multiple control modes and operating constraints. Thus, a strategy for control limit handling in power flow calculations is proposed, while considering a discrete passive shunt capacitor bank in the device. Moreover, an OPF model of the device is proposed and explained in detail, representing all the device control and physical limits as constraints in the mathematical formulation, so that the HPFC can be optimally dispatched as a part of the transmission system control assets; this model is used to determine the optimal ratings of the device based on a cost – benefit analysis. The proposed power flow and OPF models are tested and validated based on several loadability studies on a two-area benchmark test system. The HPFC power flow model is also tested and applied to a detailed model of Ontario grid and its neighboring networks with more than 6000 buses. The analyses demonstrate the application of the models for planning and operation studies, evaluating the performance and the effectiveness of the device based on realistic studies and scenarios.
Second, the merits and the added value of the HPFC application to distribution systems are discussed here through detailed modeling and time-domain simulations, examining its impact on a distribution network under different conditions. Thus, a detailed dynamic representation of the HPFC is developed and implemented in PSCAD/EMTDC, describing and proposing control strategies to properly operate this controller in…

▼ There is a general consensus worldwide for a need
to increase the capacities of transmission lines by not physically
altering the transmission structures. Amidst this challenge,
dynamic thermal rating (DTR)
system appears as an appropriate
option. Besides that, many countries have also pledged to integrate
wind energy sources into their power networks. Taking these as
motivations, the purpose of this thesis is to carry out the
reliability analysis of DTR
system for transmission lines. The two
main standards - IEEE 738 and CIGRE, use for calculating the line
rating of overhead lines has been analysed and compared. It was
demonstrated that the two standards yield insignificant differences
in their calculated line ratings. A new methodology that can
systematically assess the reliability and risk of any DTR
system
designs was proposed in this thesis. In the reliability assessment
part, methods such as the event tree analysis (ETA), risk reduction
worth (RRW) and wide range method (WRM) were used. The risks of DTR
systems were evaluated by implementing them in the IEEE 24-bus
reliability test network (RTN). The network’s loss of load and the
percentages of the conductor loss of tensile strength constitute
the risks of DTR systems. In the risk assessment part, a
multiple-linear regression (MLR) model was proposed to estimate
missing weather values during the failure of DTR sensors. Results
in this thesis show that the MLR model is accurate and has only
estimation error of less than 6%. It avoids overestimating the risk
of DTR systems. An optimum DTR
system design was also selected. The
strategic placement of DTR sensors along a transmission line is an
important reliability issue too. Hence, a new DTR sensor placement
algorithm that considers the effects of DTR
system ratings on the
amount of line sagging, conductor annealing and the correlation
between DTR
system ratings and actual line ratings was proposed.
Results in this thesis show that the newly proposed algorithm
outperforms the currently published algorithm in terms of causing
no spans to sag beyond their ground clearance limits and all spans
experience lesser annealing effects. The 2-dimensional movement of
line spans in their longitude and latitude directions, which the
currently published algorithm also lacks, are considered in the
proposed algorithm. This thesis also investigates the reliability
behaviours of a power network that has DTR systems and wind farms.
The proposed methodology for achieving that considers the
reliability of transmission lines, DTR systems, conventional
generators and wind turbines. The chronological behaviour of DTR
ratings and wind farm power outputs was modelled using the
auto-regressive and moving-average (ARMA) model. The correlations
between the ARMA models were also considered. Results in this
thesis show that by considering the correlation effects, the
network’s reliability indices are not over and under estimated. A
new reliability index for describing the amount of wind power
integration named as Expected Wind Power Delivered…

▼ This dissertation develops an object-oriented distribution
system distributed quasi-
dynamic state estimator (DS-DQDSE) that constantly monitors the states of the distribution
system and provides the validated data to the control center. In particular, the dissertation presents a distributed and seamless infrastructure starting from measurement data from sensors installed across distribution systems to estimated states and
system model output from the state estimator. To automate the whole procedure as well as to guarantee the accuracy of the output results from the state estimator, an object-oriented physically based high-fidelity device modeling approach is adopted. Given measurements and device models from a selected section, a network-level measurement model is created. The network-level measurement model is augmented with derived, pseudo, and virtual measurements to achieve observability and increase redundancy. The measurement model is then processed by the state estimator, which provides the best estimates of the monitored
system and the confidence level that evaluates if the measurements are consistent with the
system model. The output of the state estimator including estimated states, estimated measurements, and validated model of the monitored
system are then transmitted to the control center where the states and the model of the whole
system are synthesized. Since the designed DS-DQDSE adopts quasi-
dynamic state estimation (QDSE) while conventional state estimator adopts static state estimation (SSE), a comparison study between QDSE and SSE is presented. Furthermore, the developed DS-DQDSE is applied on two real feeder models. The results show that the developed DS-DQDSE is applicable to the distribution systems with DER penetration.

▼ Renewable energy has a significant potential to reduce global carbon emissions and secure long-term sustainable power supply. Higher penetration of renewable energy, however, is largely hindered by the inherent variability and intermittency of renewable resources, and renewable energy is generally considered as non-dispatchable. In other words, rather than control and dispatch the renewable energy economically, grid operators must arrange other generation units in response to what produced by wind turbines or solar panels in order to maintain network stability and meet reliability parameters.This motivates the development of microgrids supplied by renewable energy resources. Either grid-connected or islanded, these decentralized power systems are believed to be a promising solution to achieve higher penetration of clean energy in the future. Given proper control of storage units and communications with the energy market, the non-dispatchable energy can be regulated to reduce the difficulty of power scheduling in the grid operation.Battery energy storage systems (BESS) are used in many research to make renewable energy more controllable and usable on demand. Assisted by appropriate prediction techniques and control algorithms, BESS can store part of the generated renewable energy and supply some stored energy at different periods, so that the actual power dispatched can meet the required operating criteria.The main focus of this thesis is the optimal control strategy of microgrids with renewable energy systems and battery energy storage systems. The control algorithms introduced in this thesis are developed to maximize the profit and minimize the energy cost in microgrids, which require predicted data on renewable power, temperature, electricity price, and load demand. In comparison with many previous studies in this area, we developed some novel algorithms that have an emphasis on the battery lifetime degradation and computation speed, which can be critical in achieving the optimal dispatch in microgrids.

▼ Micro-combined heat and power systems (MCHP) provide an efficient, decentralised means of power generation that can complement the composition of the electricity generation mix. However, intermittent load conditions, transient
system behaviour and ensuring self-sufficiency represent challenges that MCHP systems currently on the market need to address.
System efficiency and run times can be increased by combining MCHP units with thermal and electric energy storage (EES) systems, decoupling energy supply and demand. When local generation of energy is complemented with energy storage during times of high supply and with discharge of stored energy during periods of high demand, self-sufficiency can be increased. Reducing demand at peak times makes the electricity grid more resilient and potentially lowers electricity costs for consumers.Two simulation models of MCHP systems based on thermodynamic principles were developed and combined with data from an MCHP test stand at the Technology Centre Energy (TCE), Univ. Applied Sciences Landshut, Germany.
Dynamic tools capable of handling transient
system behaviour are required to assess MCHP efficiency beyond a mere static analysis based on steady-state design parameters. A range of analysis tools were used, such as exergy, degree of self-sufficiency, peak time coverage and load duration curves.The concept of exergy allows direct comparison of different forms of energy. Exergetic definitions for different operational
system states were combined to continuously quantify overall
system efficiency. A sensitivity analysis assessed the effect on MCHP performance under varying engine speed, thermal energy storage (TES) size and fluid storage temperature. Selecting specific TES fluid temperatures can improve
system efficiency.A quantitative assessment was made on how the existing TCE control logic behaved and could be improved. It had been implemented to optimise MCHP unit run time, taking energy storage charging levels into account. It was determined how the MCHP unit and EES
system can complement each other to benefit the
system performance. Supply composition characteristics were identified that lead to higher load coverage by MCHP-generated electricity. Incorporating an EES
system has a significant impact on balancing supply and demand and also ensures longer MCHP run times. Improvements to the
system control logic were proposed to increase self-sufficiency and enhance electrical demand coverage during peak time.

▼ This thesis primarily focuses on studying the impact of Distributed Generation (DG) on the electromechanical transients in the electric grid (distribution, transmission or combined transmission and distribution (TandD) systems) using a Three Phase Dynamics Analyzer (hereafter referred to as TPDA). TPDA includes
dynamic models for electric machines, their controllers, and a three-phase model of the electric grid, and performs three-phase
dynamic simulations without assuming a positive sequence network model. As a result, TPDA can be used for more accurate investigation of electromechanical transients in the electric grid in the presence of imbalances.
At present, the Electromagnetic Transient Program (EMTP) software can be used to perform three-phase
dynamic simulations. This software models the differential equations of the entire electric network along with those of the machines. This calls for solving differential equations with time constants in the order of milliseconds (representing the fast electric network) in tandem with differential equations with time constants in the order of seconds (representing the slower electromechanical machines). This results in a stiff set of differential equations, making such an analysis extremely time consuming. For the purpose of electromechanical transient analysis, TPDA exploits the difference in the order of time constants and adopts phasor analysis of the electric network, solving differential equations only for the equipment whose dynamics are much slower than those of the electric network. Power Flow equations are solved using a graph trace analysis based approach which, along with the explicit partitioned method adopted in TPDA, can eventually lead to the use of distributed computing that will further enhance the speed of TPDA and perhaps enable it to perform
dynamic simulation in real time .
In the work presented here, first an overview of the methodology behind TPDA is provided. A description of the object oriented implementation of TPDA in C++/C# is included. Subsequently, TPDA is shown to accurately simulate power
system dynamics of balanced networks by comparing its results against those obtained using GE-PSLF®. This is followed by an analysis that demonstrates the advantages of using TPDA by highlighting the differences in results when the same problem is analyzed using a three-phase network model with unbalances and the positive sequence network model as used in GE-PSLF®. Finally, the impact of rapidly varying DG generation is analyzed, and it is shown that as the penetration level of DG increases, the current and voltage oscillations throughout the transmission network increase as well. Further, rotor speed deviations are shown to grow proportionally with increasing DG penetration.

▼ As control systems become more sophisticated, more
accurate
system models are needed for control law design and
simulation. In this research, a nonlinear
dynamic model of a
quadcopter UAV is presented and model parameters are estimated
off-line using in-flight experimental data. In addition, a
model-based classical control law for the quadcopter UAV is
designed, simulated, and then deployed in UAV flight tests. The
intent of this research is to identify a model which may be simple
enough to easily use for control law design, and accurate enough
for simulation. In addition, a model-based classical control law is
designed to for flight control.The parameters of the nonlinear
dynamic model are estimated with the Linear Least Squares Error
method. In-flight disturbances are introduced in flight tests to
ensure frequency rich data. The performances of different models
are compared using validation flight test data to select an
accurate model. This model is used as the simulation model and the
design model. Model-based control law design techniques are used to
create a flight control law which provides good performance both in
the simulator, as well as when deployed to the quadcopter.To
perform these tests, the Real-Time - Marseille Grenoble Project
software is used for the creation of ground station programs and
flight control algorithms in Simulink. This test environment
integrates a VICON camera systems, QuaRC Real Time
system, a 3DR
APM 2.6 micro-controller unit, and a Gumstix Overo AirSTORM
micro-controller unit to create a low-cost quadcopter research
platform.

▼ The fundamental character of excitation
system is to provide the direct-current power for field windings for synchronous generators. Excitation control
system controls the generator output voltage and reactive power by varying the field windingâs currents. Therefore, it can improve the transient stability of power
system.
The thesis proposed a process for modeling and simulation on a brushless coal-fired unit, since the 40 years-old magnetic amplifier (Type WMA MAG-A-STAT) Automatic Voltage Regulator (AVR) was replaced by a Programmable Logical Controller based digital redundancy
system, for the purpose to verify the excitation
system model and
dynamic response gains in the future power
system study. To establish the generator excitation
system and simulations on a popular software program MATLAB/SIMULINK, we wish to manipulate the effective and precise simulation test on a personal-computer and apply Particle Swarm Optimization (PSO) to find the global optimal solution for AVR controller settings. This thesis contributes in building a reliable excitation
system model with
dynamic response figures for power
system network planning and dispatch.

▼ Traditional Chinese Medicine (TCM) diagnosis is based on four standard approaches, i.e., observation, smelling/listening, inquiry, and palpation. Observation tops the four ways of TCM diagnosis and tongue corresponds to the major
subject of focus during observation. Traditional teaching methodology, namely, classroom lecture and textbook with a limited number of illustrations, were usually the major means of acquiring knowledge relevant to tongue diagnosis. The exemplary illustrations were usually captured under poorly controlled lighting environment and printed with low color quality. The teaching material cannot be updated dynamically and the static assessment questions cannot be adjusted to meet the needs of each individual learner. The limitations in terms of learning location, time and type, and teaching and assessment methods leave much to be desired. With the help of computer technology, a diversified digital learning and assessment platform is constructed to lift these aforementioned constraints.
In light of the pitfalls of traditional TCM education and static assessment, this paper focuses on the
dynamic assessment
system of tongue diagnosis based on Mashup technique (DASTD). The continuum of assessment is dynamically adapted according to specific userâs answering pattern of previous questions. Supplemented by the teaching materials constantly updated through the Mashup technique, the user is provided with pertinent information tailored to his needs.
Dynamic assessment, coupled with Mashup-powered digital education, form an efficient framework for the learning of TCM tongue diagnosis.
34 college students, ranging from 1st to 3rd year, in TCM department are tested by the DASTD developed. The efficacy of the DASTD is evaluated based on the pre-test and post-test performance, with interleaving learning sessions targeting on the weakness of the student under test. The result of t-test demonstrates that significant difference is reached between gain scores of pre- and post-tests, and positive correlation between gain scores and length of time spent on learning, while no significant differences between the gender and post-test gain score, and the years of students in school and the progress in gain score.

dynamic time warping to find out the state of appliance. To increase the speed of recognition, we divide waveform into four parts and use
dynamic time warping to find out the state of appliance. In this thesis, we identify five appliances by waveform identification algorithm. The recognition rate can reach 73.72%. And we divide waveform into four parts and use
dynamic time warping to find out the state of appliance. The recognition rate can also reach 70.47%, and it also consume 50% of time. So this method for appliance recognition

▼ Big data is not only a revolutionary concept but one thing which has been deeply rooted in people's subconscious since long time ago. With the development of this trend, not only service but also manufacturing industry has been involved in it.People may start to use big data unconsciously and no one can afford to neglect it.Our life becomes more and more convenient with the advancement of science and technology ,and the focus of many electronic products has been set on the maximum function with minimum weight and thickness.Therefore, functions of a number of integrated circuits have been enclosed into one single module instead of the traditional semiconductor, which makes yield-improvement the key factor to control cost.
In the study, data mining techniques were used to uncover millions of test data, and
dynamic programming model simulation was used to compare the correlation between each factor which result in the material combination for the highest yield, and the data provide the base of material matrix for planner to do decision analysis .
In this study,
system simulation is applied to related data to get the prospective results, which will simplify the complex mathematical process , reduce mistake from human error and improve accuracy. One just need to modify the parameter for different input material combination to simulation program to predict production output result.Besides of time-saving, based on this simulated output result, decision maker can improve his sensitivity and prepare contingency plan in advance to ensure the manufacturing plant always achieving the highest yield.

▼ This paper investigates the impact of income inequality on grand total crime, larceny and violent crime by using the
dynamic panel data of 20 cities and counties in Taiwan during 1998 to 2010.
The empirical results show that income inequality has a significant positive impact on grand total crime, larceny and violent crime, but unemployment rate and the proportion of the population between 15 and 64 years old both have no significant influence on three kinds of crimes. Moreover the effect of the other explanatory variables is significant on at least one kind of crimes. The empirical results also support that the criminal expected utility theory, social anomic, disorganization, conflict and strain theories are helpful to explain the criminal behavior of Taiwan.

▼ The starting point is that the current energy system is largely dependant on fossil fuels. This phenomenon, which is labelled as carbon lock-in by Unruh (2000), makes the breakthrough of renewable energies long, slow, and tedious. The most suitable theoretical approach to analyse the development, diffusion and implementation of emergent technologies, such as renewable energies, is the Technological Innovation Systems' (TIS) perspective as developed by Carlsson and Stanckiewicz (1991). This approach focuses on a particular technology and includes all those factors (institutions, actors, and networks) that influence its development. Recent research has identified several so-called System Functions that need to be fulfilled for a TIS to support successfully the evolution of a technology. In this paper we will use the following set of System Functions: F1: Entrepreneurial Activities, F2: Knowledge Development (learning), F3: Knowledge Diffusion through Networks, F4: Guidance of the Search, F5: Market Formation, F6: Resources Mobilisation, F7: Counteracting Resistance to Change (also Support from Advocacy Coalitions). By focusing on the System Functions the key processes that occur in a system which influence the development, diffusion and implementation of that technology will be identified and insight will be gained in the system dynamics. The System Functions are not independent but interact and influence each other. The nature of interactions whether they are positive or negative will influence the performance of the system respectively. Positive System Function fulfilment can lead to positive, i.e. virtuous cycles of processes that strengthen each other and lead to the building up of momentum that creates a process of creative destruction within the incumbent system (Jacobsson and Bergek 2004). According to the same reasoning, a system in decline is characterised by one or more vicious cycles, where the System Functions interact and reinforce each other in a negative way. The results from the case studies showed that different functional patterns occurred for the Biomass Innovation Systems. These can be divided into virtuous and vicious cycles. In the case of virtuous cycles a successful diffusion of the respective technologies occurred (for example biomass digestion in Germany and biomass co-firing in the Netherlands), whereas low diffusion is observed for the technologies (for example biomass digestion, biomass gasification and stand-alone biomass combustion in the Netherlands) where vicious cycles dominated the system. Furthermore, the findings show that biomass technologies go through long-term trajectories (10-30 years) of development, diffusion and implementation. However, the Dutch government only provided short-term policies and removed all support when the technical problems were not solved within this short term. In order to accelerate the diffusion of biomass energy technologies a long-term and stable guidance by the government is needed where time and space for trial and error are provided, where a market…

▼ Health care expenses are growing faster than the GDP in the Netherlands. The demand for health care will grow even more substantially in the future due to an ageing population. Innovative efforts can contribute to more efficient health care services. At the same time the quality can be improved for patients and citizens. Despite tremendous opportunities, innovating in this sector is complex and involves many actors. This research attempts to obtain insights in how different actors are involved in the service innovation process.
The role of various actors is approached from a regional innovation
system (RIS) perspective.
Dynamic service innovation capabilities (den Hertog et al., 2010) are used to explain and analyse different aspects of the service innovation process. How these
dynamic capabilities are distributed among participants indicates the importance of various actors participating in the innovation process. An answer is formulated to how the RIS enables and supports health care service innovation.
Three service innovation cases are investigated in the Rotterdam area. The research furthermore points out the importance of user pilots, co-developing and an open innovation structure.

▼ O presente trabalho discorre sobre os principais fatores que influenciam o projeto do sistema de posicionamento dinâmico (SPD) de um navio aliviador. Os fatores discutidos estão relacionados às questões de confiabilidade de sistemas e às características dos atuadores tipicamente utilizados em embarcações com SPD, tais como, dutos e azimutais. Em relação à confiabilidade de sistemas, os métodos de avaliação por diagramas de blocos e análise de modos de falha e efeitos (FMEA) são discutidos com a aplicação direcionada aos navios aliviadores com SPD. O uso de banco de dados de incidentes de operações com sistemas flutuantes com SPD também é comentado. As alternativas mais utilizadas de arranjo propulsivo para navios aliviadores são apresentadas e analisadas. As interações hidrodinâmicas entre casco-atuador, atuador-atuador e atuador-corrente são apresentadas e comentadas. Ensaios realizados em tanque de provas com propulsores em duto e azimutais instalados em modelos em escala reduzida são apresentados. O texto apresenta a execução de um projeto de dimensionamento propulsivo de um navio aliviador com SPD que opera em águas brasileiras. Para tanto, um procedimento de projeto é sugerido com as seguintes etapas: estudo dos pontos de operação, definição de requisitos de projeto, cálculo de estimativas iniciais, tomada de decisão para a escolha do arranjo propulsivo pelo método de análise hierárquica (AHP), análise de confiabilidade do SPD por FMEA e, por fim, avaliação de desempenho. A avaliação do desempenho do sistema propulsivo projetado é realizada por diagramas de capacidade e simulações dinâmicas. Uma breve comparação entre navios aliviadores com classificações diferentes é realizada e comentada.

▼ Accurately modeling power system loads is essential in
simulation-based power system planning and operation studies. Since
large industrial facilities such as petro-chemical plants and paper
mills are major power system loads, they must be modeled properly.
Utilizing the concept of the template-based load modeling technique
for industry facilities, this thesis investigates the modeling of
paper mills for power system dynamic studies. A systematic approach
with representative data is established for constructing equivalent
dynamic models of the Kraft type of paper mills. Case studies
demonstrate that the proposed model can capture the dynamic
behavior of paper mill facilities adequately and accurately. This
thesis also investigates the modeling of DC (motor) drives and
their collective dynamic responses for system dynamic studies. The
DC drive is one type of elementary load, the modeling of which has
not been fully studied in the past. It is also a major load
component in paper mills. This work develops an equivalent dynamic
model of DC drives, and a model aggregation technique. Simulation
results demonstrate the accuracy and usefulness of the proposed
model.
