Experimental Evaluation Of Friedel’S Salt For Chloride Removal In Road Salt-Impacted Stormwater And Lakes, Marwan Alhinaai Apr 2025

Experimental Evaluation Of Friedel’S Salt For Chloride Removal In Road Salt-Impacted Stormwater And Lakes, Marwan Alhinaai

Masters Theses

Road salt (e.g., NaCl) application in cold-temperature regions has increased Cl- concentrations in freshwater. Removing Cl- from water is challenging because it’s highly soluble. This paper is the first to demonstrate and characterize the removal of Cl- from stormwater by Friedel’s salt (Ca4Al2(OH)12Cl2(H2O)4) precipitation (FSP), achieved by adding calcium oxide (CaO) and sodium aluminate (NaAlO2). Laboratory tests were done on Cl- removal with FSP using a range of Ca/Al/Cl ratios in deionized (DI) water and in stormwater samples impacted by road salt. Even the lowest doses resulted in significant removal of Cl- with maximum removal rates for comparable Ca/Al/Cl ratios …

“Synchronized Parenting Is Like Mixing Oil And Water”: Reimagining Parental Control For Co-Parenting In The Divorced Households, Prakriti Dumaru, Audrey Flood, Mahdi Nasrullah Al-Ameen Apr 2025

“Synchronized Parenting Is Like Mixing Oil And Water”: Reimagining Parental Control For Co-Parenting In The Divorced Households, Prakriti Dumaru, Audrey Flood, Mahdi Nasrullah Al-Ameen

Computer Science Student Research

Children from divorced households are granted access to devices (e.g., smartphones, tablets), helping them to maintain meaningful contact with both parents. However, regulating their device usage across two households presents unique co-parenting challenges, which are little studied in the existing literature on parental mediation. As we begin to address this gap, we used low-fidelity prototype designs, guided by the principles of fostering open communication and instilling self-regulation. We evaluated those designs (presented in the form of storyboards) through semi-structured interviews with 23 divorced parents, whose children are active Internet users and aged 13 years or below. Based on our analysis, …

Lead Telecommunications Cables: A Call For Concern?, Zachary Young Apr 2025

Lead Telecommunications Cables: A Call For Concern?, Zachary Young

Michigan Journal of Environmental & Administrative Law

From the late 1800s until the 1950s, telecommunication companies across the United States utilized lead casing to protect their telecommunication lines. As technology developed and different types of plastic coatings were created, telecommunication companies phased out the use of lead cables. However, the lead cables remain in the air and buried in the ground, even continuing to provide telephone service for some. The failure to remove these cables, most of which are not in use anymore, has generated a slew of issues for the modem-day telecommunication companies that have inherited these cables from their predecessors. As the protective casing decays, …

Perspectives On Gaming Throughout The Years, Noh Fekre Apr 2025

Perspectives On Gaming Throughout The Years, Noh Fekre

ART 108: Introduction to Games Studies

Video games are a lot younger of an art form compared to other mediums like books or movies which means how they fit into our culture isn’t really set in stone yet. They have existed for a while but got their first big boom through arcades and home consoles. I want to look at how video games present themselves differently to other mediums and how that might have affected their perception amongst the general populace while also looking at how that perception has changed over time due to how games have changed themselves.


When The Audience Takes The Controller: How Streaming Is Changing The Way We Play Games, Lea Wilhelmer Apr 2025

When The Audience Takes The Controller: How Streaming Is Changing The Way We Play Games, Lea Wilhelmer

ART 108: Introduction to Games Studies

For decades, video games have been understood as solitary experiences. A player would sit alone or with a small group, controller in hand, navigating digital worlds where every action, decision, and outcome was shaped by their own input. At its core, gaming was personal. The lines between the audience and player were clearly drawn. The player was the one actively involved in the game, while everyone else was an observer, watching from the sidelines. This traditional model has seen significant transformation in the last decade, as the rise of streaming platforms like Twitch, YouTube Gaming, and other similar services radically …


Redefining Fun: How Realism And Effort Engage Players In Video Games, Marsel Abdullin Apr 2025

Redefining Fun: How Realism And Effort Engage Players In Video Games, Marsel Abdullin

ART 108: Introduction to Games Studies

In the current era of video game development, the gaming industry frequently pursues instant gratification, creating a landscape for immediate and empowering rewards. Current trends clearly show that experiences allow players to become superhuman or extraordinary beings with very little difficulty, satisfying a common desire for escapism and power. This suggests that “fun” is commonly associated with ease, speed, and constant positive feedback. However, my counter-argument is the emergence of games such as Kingdom Come: Deliverance and Red Dead Redemption 2. These games operate with a different game design and philosophy. In fact, they embrace slowness, hardship, and the detailed …

Nothing Is Off Limits, But Not Everything Is Done Right: Exploring Ineffability, Alejandro Maciel Apr 2025

Nothing Is Off Limits, But Not Everything Is Done Right: Exploring Ineffability, Alejandro Maciel

ART 108: Introduction to Games Studies

Games are capable of addressing absolutely anything. No topic is too big, too controversial, or too emotional. but not everything is done well; the problem isn't the subject, it's always the delivery. When the developers approach heavy topics without care, they risk doing harm. bwhen they do their research and consult communities and write with purpose, the result can be transformative. Representation, when handled with attention, isn't political correctness; it's simply good storytelling. it's how games become more than entertainment. They become tools for empathy, education, and more valuable connections

Research Collection School Of Computing and Information Systems

Image generation technology has brought significant advancements across various fields but has also raised concerns about data misuse and potential rights infringements, particularly with respect to creating visual artworks. Current methods aimed at safeguarding artworks often employ adversarial attacks. However, these methods face challenges such as poor transferability, high computational costs, and the introduction of noticeable noise, which compromises the aesthetic quality of the original artwork. To address these limitations, we propose a Structurally Imperceptible and Transferable Adversarial (SITA) attacks. SITA leverages a CLIP-based destylization loss, which decouples and disrupts the robust style representation of the image. This disruption hinders …


Comadice: Offline Cooperative Multi-Agent Reinforcement Learning With Stationary Distribution Shift Regularization, The Viet Bui, Tien Mai, Hong Thanh Nguyen Apr 2025

Comadice: Offline Cooperative Multi-Agent Reinforcement Learning With Stationary Distribution Shift Regularization, The Viet Bui, Tien Mai, Hong Thanh Nguyen

Research Collection School Of Computing and Information Systems

Offline reinforcement learning (RL) has garnered significant attention for its ability to learn effective policies from pre-collected datasets without the need for further environmental interactions. While promising results have been demonstrated in single-agent settings, offline multi-agent reinforcement learning (MARL) presents additional challenges due to the large joint state-action space and the complexity of multi-agent behaviors. A key issue in offline RL is the distributional shift, which arises when the target policy being optimized deviates from the behavior policy that generated the data. This problem is exacerbated in MARL due to the interdependence between agents' local policies and the expansive joint …
