Semantic segmentation of longitudinal thermal images for identification of hot and cool spots in urban areas

no code implementations6 Oct 2023 Vasantha Ramani, Pandarasamy Arjunan, Kameshwar Poolla, Clayton Miller

The masks generated using the segmentation models were then used to extract the temperature from thermal images and correct for differences in the emissivity of various urban features.

District-scale surface temperatures generated from high-resolution longitudinal thermal infrared images

1 code implementation3 May 2023 Subin Lin, Vasantha Ramani, Miguel Martin, Pandarasamy Arjunan, Adrian Chong, Filip Biljecki, Marcel Ignatius, Kameshwar Poolla, Clayton Miller

The rooftop infrared thermography observatory with a multi-modal platform that is capable of assessing a wide range of dynamic processes in urban systems was deployed in Singapore.

Mobile Energy Storage in Power Network: Marginal Value and Optimal Operation

no code implementations17 Mar 2023 Utkarsha Agwan, Junjie Qin, Kameshwar Poolla, Pravin Varaiya

This paper examines the marginal value of mobile energy storage, i. e., energy storage units that can be efficiently relocated to other locations in the power network.

Longitudinal thermal imaging for scalable non-residential HVAC and occupant behaviour characterization

no code implementations17 Nov 2022 Vasantha Ramani, Miguel Martin, Pandarasamy Arjunan, Adrian Chong, Kameshwar Poolla, Clayton Miller

It is observed that for the water-cooled system, the difference between the rate of change of the window and wall can be used to extract the operational pattern.

Electric Vehicle Battery Sharing Game for Mobile Energy Storage Provision in Power Networks

no code implementations14 Sep 2022 Utkarsha Agwan, Junjie Qin, Kameshwar Poolla, Pravin Varaiya

In this paper, we consider two types of EV drivers who may be willing to provide mobile storage service using their EVs: commuters taking a fixed route, and on-demand EV drivers who receive incentives from a transportation network company (TNC) and are willing to take any route.

Asset Participation and Aggregation in Incentive-Based Demand Response Programs

no code implementations23 Aug 2022 Utkarsha Agwan, Costas J. Spanos, Kameshwar Poolla

We develop a probabilistic model for the curtailment capability of these assets, and use it to derive analytic expressions for the optimal participation (i. e., promised curtailment) and profitability from the DR asset perspective.

Are Ensemble Classifiers Powerful Enough for the Detection and Diagnosis of Intermediate-Severity Faults?

no code implementations7 Jul 2020 Baihong Jin, Yingshui Tan, Yuxin Chen, Kameshwar Poolla, Alberto Sangiovanni Vincentelli

Intermediate-Severity (IS) faults present milder symptoms compared to severe faults, and are more difficult to detect and diagnose due to their close resemblance to normal operating conditions.

Impact of Congestion Charge and Minimum Wage on TNCs: A Case Study for San Francisco

no code implementations5 Mar 2020 Sen Li, Kameshwar Poolla, Pravin Varaiya

Both charges reduce the number of TNC trips, but this reduction is limited by the wage floor, and the number of TNC vehicles reduced is not significant.

Learning Robustness with Bounded Failure: An Iterative MPC Approach

1 code implementation22 Nov 2019 Monimoy Bujarbaruah, Akhil Shetty, Kameshwar Poolla, Francesco Borrelli

We propose an approach to design a Model Predictive Controller (MPC) for constrained Linear Time Invariant systems performing an iterative task.

EnergyStar++: Towards more accurate and explanatory building energy benchmarking

1 code implementation30 Oct 2019 Pandarasamy Arjunan, Kameshwar Poolla, Clayton Miller

Even more importantly, a set of techniques is developed to help determine which factors most influence the score using SHAP values.

A Queuing Approach to Parking: Modeling, Verification, and Prediction

no code implementations29 Aug 2019 Hamidreza Tavafoghi, Kameshwar Poolla, Pravin Varaiya

Based on the queuing model, we propose two prediction methods, a microscopic method and a macroscopic method, that provide a real-time probabilistic forecast of parking occupancy for an arbitrary forecast horizon.

Detecting and Diagnosing Incipient Building Faults Using Uncertainty Information from Deep Neural Networks

no code implementations18 Feb 2019 Baihong Jin, Dan Li, Seshadhri Srinivasan, See-Kiong Ng, Kameshwar Poolla, Alberto~Sangiovanni-Vincentelli

Early detection of incipient faults is of vital importance to reducing maintenance costs, saving energy, and enhancing occupant comfort in buildings.

A One-Class Support Vector Machine Calibration Method for Time Series Change Point Detection

no code implementations18 Feb 2019 Baihong Jin, Yuxin Chen, Dan Li, Kameshwar Poolla, Alberto Sangiovanni-Vincentelli

The One-Class Support Vector Machine (OC-SVM) is a popular machine learning model for anomaly detection and hence could be used for identifying change points; however, it is sometimes difficult to obtain a good OC-SVM model that can be used on sensor measurement time series to identify the change points in system health status.
