Summary: Association rule mining is widely used to extract hidden operation patterns from building operational data, but most of the generated rules are not useful. An analysis of over 100,000 association rules from a chiller plant reveals that useful rules are related to faults, control strategies, abnormal and normal operation patterns, but they only make up a small percentage. Common statistics indexes are ineffective in distinguishing between useful and useless association rules.

Summary: Technological advances have made it possible to generate diverse data in various applications, with the health sciences seeing a record amount of data being produced. Utilizing data can accelerate scientific advances, but proper integration of methods and domain knowledge expertise is crucial to generate and analyze big data. The lack of well-trained data scientists, especially in resource-limited settings like Africa, highlights the importance of building capacity in health data science through activities like graduate-level training and stakeholder engagement.

Summary: The search for new alloys with improved properties is a continuous process with infinite combinations and amounts of alloying elements. Advancements in machine learning have made navigating this vast search space possible. However, training machine learning models and tuning their hyper-parameters to make accurate predictions can be time-consuming and require high-performance computing resources. In this study, a generic approach is presented to accelerate alloy discovery using high throughput CALPHAD calculations, synthetic data generation, and data mining. As a demonstration, super bainitic steels that form bainite at 200 degrees C in lower transformation times are designed.

Summary: This study focuses on the vertical wind conditions as a main external factor that limits the energy assessment of high-rise buildings in urban areas. Traditional tools for energy assessment of buildings use a universal vertical wind profile estimation, without taking into account the unique wind speed in each direction induced by the various shapes and configurations of buildings in cities. To address this limitation, the study developed an omnidirectional urban vertical wind speed estimation method using direction-dependent building morphologies and machine learning algorithms.

Summary: This paper compares two main approaches to consider uncertainties in model predictive control (MPC) for buildings: robust and stochastic MPC. The results show that compared to a deterministic MPC, the robust MPC increases the electricity cost while providing complete temperature constraint satisfaction, while the stochastic MPC slightly increases the electricity cost but fulfills the thermal comfort requirements.

Summary: This research introduces an innovative resilient design framework that optimizes building performance by considering a holistic life cycle perspective and accounting for climate projection uncertainties. The study finds that future climate scenarios significantly impact building life cycle performance, with wall U-value, windows U-value, and wall density being major factors. By using ensemble learning and optimization algorithms, predictions for carbon emissions, cost, and indoor discomfort hours can be made, and the best resilient design scheme can be selected. Applying this framework leads to significant improvements in building life cycle performance.
