Model-data fusion in digital twins of large scale dynamical systems
(2022-07)
Digital twins (DTs) are virtual entities that serve as the real-time digital counterparts of actual physical systems across their life-cycle. In a typical application of DTs, the physical system provides sensor measurements ...
Viscoelastic phenomena in roll-to-roll manufacturing - Two case studies of industrial relevance
(2020-12)
In the current manufacturing industry, Roll-to-Roll (R2R) manufacturing is in high demand because of its high productivity and low cost. Many materials used for R2R manufacturing are considered viscoelastic on some time ...
Modeling web handling systems and a method for determining feedback controller gains
(2020-07)
Modeling the longitudinal dynamics and control of web handling systems requires accurate models of the primitive elements involved, and an understanding of the processes used for speed and tension control. Primitive elements ...
Development of recommendations for air mixer and sampler design and combinations thereof for performance testing of HVAC equipment
(2023-05)
Advances in equipment performance, and the development of variable speed equipment have led to stricter performance testing of HVAC&R equipment, requiring limited tolerances on capacity and efficiency measurements to 5% ...
On model-based online inverse reinforcement learning
(2020-12)
Based on the premise that the most succinct representation of the behavior of an entity is its reward structure, inverse reinforcement learning aims to recover the reward (or cost) function by observing an agent perform a ...
Modification of a high Reynolds number turbulent boundary layer with the addition of drag-reducing polymer solution
(2020-05)
Polymer drag reduction (PDR) is an active flow control technique that has drawn significant scientific examination and industrial interest for over 70 years (e.g. fluid transport in oil pipelines, surface ships, safer ...
Study on nip contact mechanics and mold extraction for predicting defects in roll-to-roll UV nanoimprint lithography
(2020-12)
Nano-scale or micro-scale structured surfaces have been proven fundamental for high-performance microelectronics. With the development of the microelectronics market, there is an increasing demand for higher-performance, ...
Experimentally validated heat exchanger refrigerant charge model and optimization of refrigerant charge for a heat pump
(2023-05)
Refrigerant charge affects the efficiency, capacity, and reliability of a heat pump, and incorrect charge can lead to increased energy consumption and decreased performance as well as potential damage to the system. ...
Development and validation of a reduced order fin-and-tube heat exchanger model
(2020-05)
Vapor compression systems are the most widely used cooling system type in heating, ventilation, and air-conditioning (HVAC) applications. Two of the four basic components of a vapor compression system are heat exchangers, ...
Single-photon oxidation of C60 by self-sensitized singlet oxygen
(2020-12)
Thanks to its unique properties, C60 has remarkably impacted nanoscience in the past two decades. Specifically, it is regarded as the most efficient singlet oxygen (1O2) photosensitizer. Yet, its oxidation by self-sensitized ...
