Piezoelectric energy harvesting from roadway
No full textEnergy harvesting technologies have attracted much attention as an alternative power source of roadway accessories in different scales. Piezoelectric materials, which have been widely used in sensor technologies due to their cost-effectiveness, are capable of producing electrical energy from mechanical energy. Therefore, piezoelectric transducers can be designed to harvest the wasted mechanical energy generated under wheel loading that can be stored in an electronic capacitor or integrated with sensors for in-situ road condition monitoring. This dissertation aims to develop a novel design of a piezoelectric transducer with optimized geometry for energy harvesting under vehicular loading in the roadway. The novel Bridge transducer with layered poling is designed to increase the piezoelectric coefficient and the relative dielectric permittivity, which produces much higher energy than traditional transducers. Finite element analysis (FEA) was conducted to predict the generated energy output and the resulted mechanical stress in the lead zirconate titanate (PZT) transducer. The results of the optimization analysis indicate that the optimized geometry parameters can generate the maximum energy output within the stress failure criteria. Later, an energy harvester module that contains multiple stacked transducers, 64 novel transducers, was fabricated and tested under single pulse and cyclic loading events. The main objectives of this part were to evaluate the energy output and fatigue behavior of the piezoelectric energy harvester using laboratory testing and numerical simulation. The analysis results showed that two different material failure models need to be considered in relation to mechanical failure of the Bridge transducer, namely tensile and shear failure. This emphasizes that the optimum design of energy module should consider the balance of energy output and fatigue life that are affected by the fabrication of a single Bridge transducer and the packaging design of the energy module. To take into account the nature of the energy harvester-pavement interaction and to achieve better computation efficiency, the effect of this interaction on pavement responses was studied using a decoupled approach. First, a 3D pavement model was built, and then the pavement responses under the tire contact stresses were calculated. The effects of energy harvester-pavement interaction at different locations, horizontally and vertically, were also analyzed. The results show that the maximum power output of the energy harvester module is around 122mW at a vehicle speed of 65mph and 3 inches embedded depth. Furthermore, embedding the energy harvesting module below 3 inches from the pavement surface is the best location to maximize both power output and service life. Finally, to reveal the potentials of some important technologies for harvesting energy from a pavement network, a case study is discussed, which uses the New Jersey roadway network as the example for analysis. The potential of electrical energy generation for thermoelectric and piezoelectric (cymbal and novel bridge design) technologies were considered. Based on available energy harvesting technologies, a thermoelectric-based pipe system covering the entire New Jersey roadway network may potentially collect 20.11 GWh electrical energy per day, while a piezoelectric transducer system may collect around 3.74 and 10.01MWh of electrical energy per day for cymbal and novel bridge transducer designs, respectively.Ph.D.Includes bibliographical referencesby Abbas Fadhil Jasi
Optimization of pavement preservation strategy considering cost and environmental impacts
No full textRoad maintenance is crucial for the purpose of retarding deterioration of pavement, which is a complex and continuous process due to the interaction of heavy traffic, environmental condition, and material aging. The combination of increased traffic and lack of appropriate maintenance causes a higher rate of degeneration in the roads. Transportation agencies need to develop a system for disseminating limited funds and decide the timing to conduct maintenance and repairs. In order to establish a cost-effective budget and achieve the optimum utilization of available resources, the agency needs to decide which maintenance treatment to use and where and when to apply it. The primary objective of this dissertation is to develop network-level pavement preservation decisions considering multiple objectives of cost and environmental impacts. This research will produce multi-objective optimization models designed to provide highway agencies with means of making road maintenance decisions among different concerns. Therefore, this study developed regression models of CO2 emissions for four vehicle types to quantify the environmental impact at the use stage. The simulated constraint boundary method (SCBM) was used as a tool to find Pareto optimal solutions for the pavement multi-objective optimization problem of minimizing agency costs and minimizing CO2 emissions by minimizing average network IRI value. This method is based on solving one objective and converting the other objective to constraint, so the decision makers need to decide first which objective should be considered as the primary objective (the objective that deserves the most attention among the competing objectives). The results show that the crack seal is still the most dominant preservation treatments compared to thin overlay although it has less effect on the reduction of IRI than the thin overlay treatment. So, the objective of minimizing agency cost controls the optimization results although the minimization of CO2 emissions was considered in the optimization process. Another method that was used in this research to achieve both objectives of minimizing agency costs and emissions is the Weighted Sum method. Weighted sum method is based on converting the two objectives into one single objective by adding both objectives together after multiplying each objective by a weighting factor. The value of weighting factor should be considerable relative to other weighting factors and comparative to its corresponding objective function. The results for the distribution of pavement preservation treatments show that less costly preservation treatments were selected for the most segments of the network when the priority of optimization was given to the objective of minimization agency cost. The treatments that have higher effectiveness on pavement condition were selected for the most segments of the network when the objective of minimization CO2 emission is the main objective compared to the other objective.Ph.D.Includes bibliographical referencesby Israa Fadhil Jasim AL-Saad

Domain Specific Design Patterns: Designing For Conversational User Interfaces
No full textDesigning conversational user interface experience is complicated because conversation comes with many expectations. When these expectations are met, we feel the interface is natural, but once violated, we feel something is amiss. The last decade witnessed human language technologies and behaviours to enable humans converse with software using spoken dialogue to access, create and process information. Less is known about the practicalities of designing chatbot interactions. In this paper, we introduce the nature of conversational user interfaces (CUIs) and describe the underlying technologies they are based on. Moreover, we define guidelines for designing conversational interfaces in various domains. This paper particularly focuses on classifying the elements and techniques used in CUI design patterns. After concluding certain challenges with CUI, we discuss important features and chatbot states to be considered in CUI design for specific domain. We envisage this study to support CUI researchers to design tailored chatbots applicable into certain domain and improve the current state of research challenges in the field of Artificial Intelligence and conversational agents
