Distribution System Optimal Operation Of Smart Homes With Battery And Equivalent Hvac Energy Storage For Virtual Power Plant Controls, Steven B. Poore, Rosemary E. Alden, Evan S. Jones, Dan M. Ionel

Electrical and Computer Engineering Graduate Research

Battery energy storage systems (BESS) that can be utilized for demand response (DR) and load shifting are limited in adoption by high capital cost. Large residential loads such as electric water heaters (EWH) and heating, ventilation and air-conditioning (HVAC) may be controlled using distributed energy resource management systems (DERMS) to perform functions like batteries, such as reducing cost and decreasing energy storage capacity requirements when implemented at the aggregate level. Increasing levels of renewable generation further incentivizes shifting loads in time through controls and energy storage to reduce curtailment and carbon footprint. This paper proposes techniques for the optimization and …

Brilliant Bird Brains: Object Recognition In Herring Gulls (Larus Argentatus Smithsonianus), Kristen M. Covino, F. Dylan Titmuss, Joseph E. Brosseau, Dora C. Donacik, Maddie E. Ellms, Alyssa R.

The ability to recognize and associate objects with prior experiences has been demonstrated in several avian taxa. Corvids, for example, recognize visual stimuli associated with negative previous experiences and will modify their behavioral responses according to the level of perceived threat. However, the extent to which similar memory-based behaviors exist in seabirds is poorly understood. Our study investigated object recognition by Herring Gulls (Larus argentatus smithsonianus) on their breeding grounds, the site of a long-term monitoring project. When handling gulls and conducting field research, researchers wear standard bicycle helmets as a protective measure against physical aggression by nesting …

Regulation Of Tumor Apoptosis Of Poriae Cutis-Derived Lanostane Triterpenes By Akt/Pi3k And Mapk Signaling Pathways In Vitro, Shuai Yue, Xi Feng, Yousheng Cai, Salam A. Ibrahim, Ying Liu, Wen Huang

Faculty Research, Scholarly, and Creative Activity

Poria cocos is traditionally used as both food and medicine. Triterpenoids in Poria cocos have a wide range of pharmacological activities, such as diuretic, sedative and tonic properties. In this study, the anti-tumor activities of poricoic acid A (PAA) and poricoic acid B (PAB), purified by high-speed counter-current chromatography, as well as their mechanisms and signaling pathways, were investigated using a HepG2 cell model. After treatment with PAA and PAB on HepG2 cells, the apoptosis was obviously increased (p < 0.05), and the cell cycle arrested in the G2/M phase. Studies showed that PAA and PAB can also inhibit the occurrence and development of tumor cells by stimulating the generation of ROS in tumor cells and inhibiting tumor migration and invasion. Combined Polymerase Chain Reaction and computer simulation of molecular docking were employed to explore the mechanism of tumor proliferation inhibition by PAA and PAB. By interfering with phosphatidylinositol-3-kinase/protein kinase B, Mitogen-activated protein kinases and p53 signaling pathways; and further affecting the expression of downstream caspases; matrix metalloproteinase family, cyclin-dependent kinase -cyclin, Intercellular adhesion molecules-1, Vascular Cell Adhesion Molecule-1 and Cyclooxygenase -2, may be responsible for their anti-tumor activity. Overall, the results suggested that PAA and PAB induced apoptosis, halted the cell cycle, and inhibited tumor migration and invasion through multi-pathway interactions, which may serve as a potential therapeutic agent against cancer.

On Site Renovation Of Degraded Pv Panels – Cost And Environmental Effective Technology, Vladislav Poulek, Igor Tyukhov, Vaclav Beranek

Faculty Research, Scholarly, and Creative Activity

The encapsulation of photovoltaic (PV) panels determines the trouble-free lifetime of the panels. The quality of PV panel encapsulating components has significantly decreased over the last 25 years. Consequently, large quantities of PV panels worldwide are experiencing degradation or damage much earlier than expected. To address this issue, an on-site renovation technology for PV panels has been developed, which involves pre-deposition diagnosis and polydimethylsiloxane (PDMS) film deposition. This technology substantially prolongs the real field lifetime of PV panels. In terms of carbon footprint, PV panel renovation is over a hundred times more effective compared to PV panel replacement. It is …

Remaining Useful Life Prediction Of Bearings With Attention-Awared Graph Convolutional Network, Yupeng Wei, Dazhong Wu

Faculty Research, Scholarly, and Creative Activity

Graph Convolutional Networks (GCNs) have recently been used to predict the remaining useful life (RUL) of bearings due to its effectiveness in revealing correlations in condition monitoring data. However, traditional GCNs use a single graph only, either a temporal-correlated graph or a feature-correlated graph without considering both temporal and feature correlations of condition monitoring data. Additionally, traditional GCNs rely heavily on pre-defined graphs to aggregate correlated features. However, the topology of these pre-defined graphs may vary depending on a pre-defined threshold for cosine similarity or covariance which might affect prediction accuracy and robustness. To address these issues, we introduce a …

Due to socio-economic and climatic changes around the world, large outdoor fires in the built environment have become one of the global issues that threaten billions of people. The devastating effects of them are indicative of weaknesses in existing building codes and standard testing methodologies. This is due in part to our limited understanding of large outdoor fire exposures, including the ones from wildland to communities and within communities. To address this problem, the Ignition Resistance Committee (IRC) of the International Association of the Fire Safety Science working group ‘Large Outdoor Fires and the Built Environment’ was established. This manuscript …

Risk-Seeking Governance, Brian J. Broughman, Matthew T. Wansley

Articles

Venture capitalists (“VCs”) are increasingly abandoning their traditional role as monitors of their portfolio companies. They are giving startup founders more equity and control and promising not to replace them with outside executives. At the same time, startups are taking unprecedented risks—defying regulators, scaling in unsustainable ways, and racking up billion-dollar losses. These trends raise doubts about the dominant model of VC behavior, which claims that VCs actively monitor startups to reduce the risk of moral hazard and adverse selection. We propose a new theory in which VCs use their role in corporate governance to persuade risk-averse founders to pursue …

Exit Engineering, Rachel Landy

Articles

How do business lawyers create value? For nearly forty years, scholars have conceptualized the business lawyer as a “transaction cost engineer” who helps contracting parties efficiently break negotiation stalemates to create more valuable deals. This theory provides meaningful insights about sophisticated corporate law practice, where outside lawyers parachute in to make one-off deals happen. However, it fails to explain the behavior of startup lawyers, who develop long-term relationships with their clients and counsel them on seemingly routine matters, well before a major transaction materializes. These lawyers are not just transaction cost engineers, they are exit engineers. This Article offers a …

Does The Federal Reserve Obtain Competitive And Appropriate Prices In Monetary Policy Implementation?, Yu An, Zhaogang Song

Research Collection Lee Kong Chian School Of Business

Many of the Federal Reserve’s (the Fed’s) monetary policy operations involve trading with primary dealers. We find that, for agency MBS, dealers charge 2.5 cents (per $100 face value) higher selling to the Fed than to non-Fed customers. Controlling for the same dealer, same security, and same trading time, this discriminatory pricing likely arises from dealers’ market power rather than inventory costs. Further, matching trade size reduces the price differential by more than half, implying that dealers’ market power greatly relates to the Fed’s purchases in large amounts, whereas the Fed’s limited breadth of counterparty choice also plays some role.

The Effect Of Microlearning And Multimedia Design On Knowledge And Skills Acquisition Of Students In E-Courses, Rene Corbeil, Didem Tufan, Maria Elena Corbeil

Teaching and Learning Faculty Publications

Although the term microlearning has been around since 2005 (Hug, 2005), its use, and research in the area, have resurged in recent years as adult learners have become increasingly more mobile and must deal with competing work, family, and educational priorities. Today’s learners, in both formal and informal academic and corporate learning environments, can benefit from microlearning’s smaller, single objective lessons that can be consumed quickly and easily. However, there are many variations of microlearning and ideas on how to create the instructional materials they include. While it may seem simple, the development process requires applying instructional design strategies and …

Social And Biological Perspectives To Investigate And Address Illegal Shooting Of Raptors, Eve Thomason, Kenneth Wallen, Todd Katzner

Raptor Research Center Publications and Presentations

Humans have shot raptors for centuries. However, in many countries these actions have been illegal since the mid-twentieth century. Despite this history, there is not a comprehensive understanding of the characteristics of this activity, its frequency, and why it occurs. We used literature review and principles drawn from ecology, sociology, and criminology to understand this problem. First, we review literature on raptor shooting globally to explore documented motivations for shooting and we describe the history of raptor shooting in the United States of America (USA). Then, to illustrate the contemporary frequency and geographic breadth of the shooting of raptors, we …

What's Not Natural Phenomena? Let's Consider A Three-Step Innovative Concept Test For Composition Of Matter Claims, Sydney Hancock

IP Theory

Biotechnology innovation is rapidly growing, especially in the realm of biotech. This growth leads to questions about patent subject matter eligibility of natural phenomena. For example, currently the human genome and microbiome are being extensively studied, bacteriophages are being edited, animals are being cloned, and CRISPR is widespread. Additionally, composition of matter patent claims give the most protection to patent holders. Therefore, knowing when a natural phenomenon veers into human innovation is important for courts, lawyers, and innovators in the era of biotechnology and genetic engineering.

Part I discusses the history of Supreme Court cases on natural phenomena subject matter …

U-Net-Lstm: Time Series-Enhanced Lake Boundary Prediction Model, Lirong Yin, Lei Wang, Tingqiao Li, Siyu Lu, Jiawei Tian, Zhengtong Yin, Xiaolu Li, Wenfeng Zheng

Faculty Publications

Change detection of natural lake boundaries is one of the important tasks in remote sensing image interpretation. In an ordinary fully connected network, or CNN, the signal of neurons in each layer can only be propagated to the upper layer, and the processing of samples is independent at each moment. However, for time-series data with transferability, the learned change information needs to be recorded and utilized. To solve the above problems, we propose a lake boundary change prediction model combining U-Net and LSTM. The ensemble of LSTMs helps to improve the overall accuracy and robustness of the model by capturing …

Multimodal astrocyte–neuron communications govern brain circuitry assembly and function. For example, through rapid glutamate release, astrocytes can control excitability, plasticity and synchronous activity of synaptic networks, while also contributing to their dysregulation in neuropsychiatric conditions. For astrocytes to communicate through fast focal glutamate release, they should possess an apparatus for Ca2+-dependent exocytosis similar to neurons. However, the existence of this mechanism has been questioned owing to inconsistent data and a lack of direct supporting evidence. Here we revisited the astrocyte glutamate exocytosis hypothesis by considering the emerging molecular heterogeneity of astrocytes and using molecular, bioinformatic and imaging approaches, together with …

Towards An Effective And Interpretable Refinement Approach For Dnn Verification, Jiaying Li, Guangdong Bai, Long H. Pham, Jun Sun

Research Collection School Of Computing and Information Systems

Recently, several abstraction refinement techniques have been proposed to improve the verification precision for deep neural networks (DNNs). However, these techniques usually take many refinement steps to verify a property and the refinement decision in each step is hard to interpret, thus hindering their analysis, reasoning and optimization.In this work, we propose SURGEON, a novel DNN verification refinement approach that is both effective and interpretable, allowing analyst to understand why and how each refinement decision is made. The main insight is to leverage the ‘interpretable’ nature of debugging processes and formulate the verification refinement problem as a debugging problem. Given …
