Adaptive Systems for Smart Buildings Utilizing Wireless Sensor Networks and Artificial IntelligenceQela, Blerim January 2012 (has links)
In this thesis, research efforts are dedicated towards the development of practical adaptable techniques to be used in Smart Homes and Buildings, with the aim to improve energy management and conservation, while enhancing the learning capabilities of Programmable Communicating Thermostats (PCT) – “transforming” them into smart adaptable devices, i.e., “Smart Thermostats”. An Adaptable Hybrid Intelligent System utilizing Wireless Sensor Network (WSN) and Artificial Intelligence (AI) techniques is presented, based on which, a novel Adaptive Learning System (ALS) model utilizing WSN, a rule-based system and Adaptive Resonance Theory (ART) concepts is proposed. The main goal of the ALS is to adapt to the occupant’s pattern and/or schedule changes by providing comfort, while not ignoring the energy conservation aspect. The proposed ALS analytical model is a technique which enables PCTs to learn and adapt to user input pattern changes and/or other parameters of interest.
A new algorithm for finding the global maximum in a predefined interval within a two dimensional space is proposed. The proposed algorithm is a synergy of reward/punish concepts from the reinforcement learning (RL) and agent-based technique, for use in small-scale embedded systems with limited memory and/or processing power, such as the wireless sensor/actuator nodes. An application is implemented to observe the algorithm at work and to demonstrate its main features. It was observed that the “RL and Agent-based Search”, versus the “RL only” technique, yielded better performance results with respect to the number of iterations and function evaluations needed to find the global maximum. Furthermore, a “House Simulator” is developed as a tool to simulate house heating/cooling systems and to assist in the practical implementation of the ALS model under different scenarios. The main building blocks of the simulator are the “House Simulator”, the “Smart Thermostat”, and a placeholder for the “Adaptive Learning Models”. As a result, a novel adaptive learning algorithm, “Observe, Learn and Adapt” (OLA) is proposed and demonstrated, reflecting the main features of the ALS model. Its evaluation is achieved with the aid of the “House Simulator”. OLA, with the use of sensors and the application of the ALS model learning technique, captures the essence of an actual PCT reflecting a smart and adaptable device. The experimental performance results indicate adaptability and potential energy savings of the single in comparison to the zone controlled scenarios with the OLA capabilities being enabled.

Does Technology = More Knowledgeable Other? an Investigation of the Effects of an Integrated Learning System on the Literacy Learning of Emergent ReadersPutman, Rebecca S. 08 1900 (has links)
Professionals in education continue to explore technology as a way to instruct young students, and there is an accompanying belief that this technology can make an educational and academic difference. Despite the high percentage of young students in classrooms using technology, the impact of this technology on the early literacy skills of young children remains largely unknown. Guided by Vygotsky’s social learning theory, this study reports a 24-week investigation on whether regular use of Istation®, an integrated learning system used by approximately 3,000,000 students in the United States, had an effect on the early literacy achievement of children in twelve kindergarten classrooms. A mixed-method, quasi-experimental design was constructed using propensity scores. Also investigated were the effects of the level of teacher literacy support on early literacy achievement and the interaction between Istation® use and the level of teacher literacy support. A descriptive discriminant analysis was performed to determine the main effect of Istation®. The level of teacher support and the interaction effect was then tested using a multivariate between-subject analysis. Results indicated that Istation® did have a statistically significant effect on the early literacy skills of the 72 kindergarten students studied and was able to explain 17.7% of the variance in group differences. Hearing and recording sounds and letter sound knowledge were the main contributors to group differences. Teacher literacy support and the interaction between teacher support and Istation were not significant. This study considers the relationship between technology and early literacy and concludes that Istation® can serve as a more knowledgeable other as students develop some early literacy skills; however, teachers are still needed to provide complete literacy instruction for young students.

Towards a learning system for process and energy industry : Enabling optimal control, diagnostics and decision supportRahman, Moksadur January 2019 (has links)
Driven by intense competition, increasing operational cost and strict environmental regulations, the modern process and energy industry needs to find the best possible way to adapt to maintain profitability. Optimization of control and operation of the industrial systems is essential to satisfy the contradicting objectives of improving product quality and process efficiency while reducing production cost and plant downtime. Use of optimization not only improves the control and monitoring of assets but also offers better coordination among different assets. Thus, it can lead to considerable savings in energy and resource consumption, and consequently offer a reduction in operational costs, by offering better control, diagnostics and decision support. This is one of the main driving forces behind developing new methods, tools and frameworks that can be integrated with the existing industrial automation platforms to benefit from optimal control and operation. The main focus of this dissertation is the use of different process models, soft sensors and optimization techniques to improve the control, diagnostics and decision support for the process and energy industry. A generic architecture for an optimal control, diagnostics and decision support system, referred to here as a learning system, is proposed. The research is centred around an investigation of different components of the proposed learning system. Two very different case studies within the energy-intensive pulp and paper industry and the promising micro-combined heat and power (CHP) industry are selected to demonstrate the learning system. One of the main challenges in this research arises from the marked differences between the case studies in terms of size, functions, quantity and structure of the existing automation systems. Typically, only a few pulp digesters are found in a Kraft pulping mill, but there may be hundreds of units in a micro-CHP fleet. The main argument behind the selection of these two case studies is that if the proposed learning system architecture can be adapted for these significantly different cases, it can be adapted for many other energy and process industrial cases. Within the scope of this thesis, mathematical modelling, model adaptation, model predictive control and diagnostics methods are studied for continuous pulp digesters, whereas mathematical modelling, model adaptation and diagnostics techniques are explored for the micro-CHP fleet. / FUDIPO – FUture DIrections for Process industry Optimization

Image-based Machine Learning Applications in Nitrate Sensor Quality Assessment and Inkjet Print Quality StabilityQingyu Yang (6634961) 21 December 2022 (has links)
<p>An on-line quality assessment system in the industry is essential to prevent artifacts and guide manufacturing processes. Some well-developed systems can diagnose problems and help control the output qualities. However, some of the conventional methods are limited in time consumption and cost of expensive human labor. So, more efficient solutions are needed to guide future decisions and improve productivity. This thesis focuses on developing two image-based machine learning systems to accelerate the manufacturing process: one is to benefit nitrate sensor fabrication, and the other is to help image quality control for inkjet printers.</p>
<p><br></p>
<p>In the first work, we propose a system for predicting the nitrate sensor's performance based on non-contact images. Nitrate sensors are commonly used to reflect the nitrate levels of soil conditions in agriculture. In a roll-to-roll system, for manufacturing thin-film nitrate sensors, varying characteristics of the ion-selective membrane on screen-printed electrodes are inevitable and affect sensor performance. It is essential to monitor the sensor performance in real-time to guarantee the quality of the sensor. We also develop a system for predicting the sensor performance in on-line scenarios and making the neural networks efficiently adapt to the new data.</p>
<p><br></p>
<p>Streaks are the number one image quality problem in inkjet printers. In the second work, we focus on developing an efficient method to model and predict missing jets, which is the main contributor to streaks. In inkjet printing, the missing jets typically increase over printing time, and the print head needs to be purged frequently to recover missing jets and maintain print quality. We leverage machine learning techniques for developing spatio-temporal models to predict when and where the missing jets are likely to occur. The prediction system helps the inkjet printers make more intelligent decisions during customer jobs. In addition, we propose another system that will automatically identify missing jet patterns from a large-scale database that can be used in a diagnostic system to identify potential failures.</p>

Increasing motivation by adapting intelligent tutoring instruction to learner achievement goalsLockhart, Tony F. 05 April 2011 (has links)
The impact of affect on learning and performance has caused many researchers in the field of cognitive psychology to acknowledge the value of motivationally supportive instruction. Goal orientation, which refers to the perceptions and behaviors of the learner in achievement situations, has been the most predominant theory in learning motivation. However, research suggests multiple components are responsible for affecting student cognitive engagement. The traditional framework distinguishes individuals who are self-motivated to master challenging tasks from those who are motivated to earn favorable judgments of performance as intrinsic and extrinsic learners, respectively. In addition, learners may be further categorized by an eagerness to ensure a positive outcome or by their vigilance in avoiding negative outcomes. As such, my research explores how these motivational categories can be utilized to construct a more robust instructional model.
The objective of this research is to evaluate the effectiveness of adaptive remediation strategies on motivation and learning performance. Research suggests the cost of integrating cognitive tasks with error analysis outweigh the benefits of sparse learning gains. However, further investigation is required to understand how feedback can improve these outcomes. The experiment presented here seeks to evaluate the adaptive instruction of two pedagogical agents embedded within two separate versions of the Virtual BNI Trainer. The basic coach uses a model of the learner's experience level to determine an appropriate level of elaboration required during remediation. In contrast, the motivationally enhanced coach uses a model of the learner's goal orientation to construct feedback that appeals to their natural disposition.
A controlled experiment was conducted to evaluate the effects of adaptive instruction on student self-efficacy, engagement, and learning performance in the Virtual BNI Training Environment. The results of this experiment are used to establish guidelines for integrating goal orientation, error analysis, and feedback within a virtual coach, to improve motivation and learning performance. In addition, these findings also indicate areas for future research.
