Sos Effectiveness Evaluation Method Based On Fuzzy Functional Dependency Network Analysis, Hongjia Su, Cheng Zhang, Fei Liu

Journal of System Simulation

Functional dependency network analysis (FDNA) enables modeling functional dependencies among equipment in a system of systems (SoS) and then computing the whole SoS effectiveness based on the effectiveness of each equipment, thus overcoming the deficiency of traditional SoS effectiveness evaluation based on tree-like index systems. However, critical parameters such as strength/criticality of dependency in this methodology currently rely on subjective empirical assignments, where the deviations resulting from subjectivity may compromise the accuracy of effectiveness evaluation. To address this limitation, this paper proposes a fuzzy FDNA (FFDNA)-based SoS effectiveness evaluation method. This method constructs a functional dependency network (FDN) model …

Multi-Agent Reinforcement Learning Method For Wargame Simulation Based On Suboptimal Demonstration Guidance, Zicong Zhou, Junjie Zeng, Yue Hu, Zhengqiu Zhu, Quanjun Yin

Journal of System Simulation

To address issues such as fixed behavior patterns and insufficient adaptability in complex adversarial environments exhibited by traditional wargame agent decision-making models, this paper proposes a multi-agent reinforcement learning method based on suboptimal demonstrations (MARLSD). The proposed method integrates reward relabeling with a self-imitation learning mechanism, effectively improving the training efficiency of multi-agent reinforcement learning algorithms in environments with large state-action spaces and sparse rewards, even when only a small number of suboptimal demonstrations are available, while encouraging agents to explore better strategies. Experimental results show that, compared with baselines such as QMIX and MAGAIL, MARLSD significantly improves performance and …

Journal of System Simulation

To address the constraints imposed by missing trajectory data in surveillance systems on the efficacy of civil aviation safety monitoring, as well as the limitations on the development and application of advanced technologies within trajectory-based operational frameworks, a completion method for trajectory based on image representation and collaborative feature perception was proposed. A conversion strategy for trajectory image representation was designed to reformulate the trajectory completion task as a deterministic image completion problem, effectively circumventing the cumulative error problem of traditional time-series data caused by the limitation of recurrent neural network inference mechanisms.A regression model fusing a multi-kernel hybrid …

Robot Trajectory Planning And Adjustment Method For Abnormal Pose Of Actuator, Lang Qin, Jiacheng Xie, Xiaojun Qiao, Xuewen Wang, Zhijie Xiao

Journal of System Simulation

To address the influence of the abnormal pose of the robot actuator on the robot trajectory, an adaptive planning and adjustment method of trajectory based on virtual-real fusion was proposed. AR technology was introduced to couple with the robot kinematics model, and the hardware dependence on multiple sensors was replaced by synchronous comparison of three-dimensional virtual and real poses; AR gestures and voice interaction were combined to simplify the operation process; based on the actual pose of the actuator, the trajectory of the robot terminal axis was dynamically adjusted. The experimental results show that this method breaks through the technical …

Hyperspectral Anomaly Detection Algorithm Based On Window Reconstruction And Collaborative Representation, Shuanghao Fan, Fang He, Jianwei Zhao, Haojie Hu, Fengchao Zhu, Xiangyang Li

Journal of System Simulation

Hyperspectral anomaly detection refers to identifying ground objects that deviate from normal background distributions and have low probability and small scales from scenes involving mixed multi- class ground objects, spectral feature overlaps, and noise interference. This technology has received extensive attention in recent years. Although collaborative representation-based anomaly detection algorithms demonstrate excellent performance in hyperspectral image anomaly detection, their time costs are too high to enable widespread application.To address this issue, this paper proposes a hyperspectral image anomaly detection algorithm based on window reconstruction and collaborative representation, which consists of two stages. Window reconstruction is performed on hyperspectral background …

Detection Method For Laboratory Ppe Compliance Wearing Based On Human Key Points, Lijun Peng, Tingqi Su, Peijin Liu, Lin He, Xiewu Zhou, Minxin Zhang

Journal of System Simulation

To address the problems of high missed detection rate and inaccurate judgment of wearing compliance when multi-scale and multi-category targets of laboratory personnel's safety protective equipment are detected in a complex laboratory environment, this paper proposes a laboratory personnel's standard personal protective equipment (PPE) wearing detection method (multi-scale multi- target joint key point detection method, MSMT-JKDM) that integrates multi-scale features and human keypoints. The multi-scale adaptive down sampling (MSA-Down) module and the cascaded group attention transformer (CGA Former) are introduced to enhance the feature representation ability of PPE (especially small targets such as goggles and gloves) in laboratory detection scenarios, …

Freeland V. Chemtob

All Decisions

The Appellate Division affirmed the lower court's decision, largely granting summary judgment to the landlord in a holdover action for use and occupancy, electricity charges, and dismissing the tenant's counterclaims. The court found the landlord provided sufficient notice of non-renewal via email under RPL § 226-c and was entitled to holdover damages and unpaid electricity charges. It also confirmed the landlord's lawful retention of the security deposit and dismissed the tenant's harassment claim. However, the court modified the order, vacating the determination that the landlord was the prevailing party for attorney's fees, as this finding was premature pending resolution of …

Data Driven Estimation Of Pore Size Using 1d Light Emissions For Laser Powder Bed Fusion Additive Manufacturing, Jose Galarza, Jorge Barron, Luis Jimenez, Tamer Oraby, Jianzhi Li, Farid Ahmed

Manufacturing & Industrial Engineering Faculty Publications

The quality assurance of the Laser Powder Bed Fusion Process (LPBF) has been extensively investigated over the last decade for in-situ monitoring of metal additive manufacturing. The process inherently generates voids within the bulk of the part, which can detrimentally affect the quality of the printed part. The characterization of these voids by estimating their size and identifying their geometrical features remains a challenge. This study introduces a Machine Learning (ML) based framework for estimating void sizes of varying geometries using layer-wise one-dimensional (1D) average light intensity signal obtained from the optical tomography system during the 3D printing of metallic …

Hedonics Of Used Car Attributes On Market Price, Alexander Bent, Jason Gutierrez

Undergraduate Economics Working Paper Series

This paper uses Rosen's paper on hedonic pricing as a framework to analyze the determinants of used car prices found in Craigslist. Using cleaned data, we observe over 43,000 listings from 2005 to 2020 and investigate factors that affect used car prices and how they interact in this market. Results show that odometer readings and condition are the strongest factors that determine price, while manufacturers, paint color, drive type, fuel type, size, and year have more ambiguous effects that depend on certain perceived attributes or conditions.

Key Determinants Of Diamond Value, Tobey Brill, Alexander Dobrovolskyi, Rayland Labayog

Undergraduate Economics Working Paper Series

This paper intends to examine the determinants of diamond pricing using a hedonic regression framework. Using the diamonds dataset from Wickham (2016), we analyze the four C’s, also known as carat weight, cut, color, and clarity. We also wanted to go deeper into this topic and look into the depth and table to see how it impacts diamond pricing. Results have displayed that carat weight greatly influences a diamond’s price, while characteristics such as clarity, color, and cut exert positive effects. Estimates were found to be statistically significant. Our findings confirm and reassure the idea that hedonic pricing accurately captures …

Social Determinants Of Low Educational Attainment, Isabelle Graham, Kevin Lieng, Aubriana Weisbach

Undergraduate Economics Working Paper Series

This paper examines how socioeconomic and demographic factors influence low educational attainment across U.S. cities. The analysis estimates both a linear regression model and a semi-log model to evaluate how poverty, unemployment, family structure, age composition, overcrowding, racial and ethnic minority share, broadband access, and housing cost burden affect the percentage of adults without a high school diploma. The results show that poverty, overcrowding, and minority share are the strongest predictors of low educational attainment, each exhibiting positive and highly significant effects. Overall, the findings highlight the role of social factors in shaping educational outcomes in high school.

This study analyzes if the 2023 rule changes affected the valuation for speed in the MLB labor market. By using a log-linear wage model and including an interaction term for stolen bases and the post-2023 indicator, we test to see if there is a speed premium in salaries. After accounting for yearly effects, the results present a statistically significant increase in the marginal value of stolen bases after the rule change shock. A placebo test was used with home runs to confirm the effects were specific to speed related metrics. The results suggest that the MLB market has and is …

Do Rural Areas Gender-Discriminate Wages More Than Metropolitan Areas?, Ali Gonzalez, Michael Montano, Brandon Sacks, Joseph Williams

Undergraduate Economics Working Paper Series

This study analyzes the gender wage gap in metropolitan versus rural areas using U.S. hourly wage data from the Bureau of Labor Statistics (BLS), for the period 2010-2025. The analysis uses regressions on a semi-log wage model and Blinder-Oaxaca decompositions to compare the gaps and separate the effects attributable to explained (endowment) differences from those attributable to unexplained (coefficient) differences. The semi-log wage model reveals a percentage wage decrease for females of approximately 17.4% in rural areas and 9.9% in metropolitan areas. The Blinder-Oaxaca decompositions further indicate that the unexplained (coefficient) component of the gap is substantially larger in rural …

Using occupational-level data from O*NET and the U.S. Bureau of Labor Statistics, we build an AI exposure index …

Simple Determinants Of Commercial Bank Failures, Matthrew Qi

Undergraduate Economics Working Paper Series

This study investigates the internal and macroeconomic determinants of commercial banking failures in the United States spanning 1959 to 2025. Using a logit model and a four-quarter lag, two models are estimated: a comprehensive model (1985–2025) and an extended panel model (1960–2025). Empirical results reveal internal CAMELS metrics are primary determinants of survival; profitability and capital adequacy defends against failures, while asset quality deterioration and management inefficiencies accelerates failure. The “too big to fail” paradigm is empirically validated. Contractionary monetary policy and labor market stress increase failure probabilities. Real GDP growth exhibits a role shift predicting commercial bank failures.

The Structural Limitations Of Mining Output Growth In Nevada, Mckinley Brown, Emma Kitchen

Undergraduate Economics Working Paper Series

This study compares short and long trends in Nevada to the production output within the mining industry. Nevada produces around 70% of the United States gold and about 15% of the world's critical minerals. From its position as one of the most resource rich mining regions globally to its emergence as a growing economic hub, mining played a central role in Nevada's economy. However, despite the industry’s importance, Nevada still faces inefficiencies in production output due to insufficient attention to key inputs such as labor, infrastructure, technology, and energy resources.

Las Vegas Casino Revenue In An Expanding Gambling Market, Kaden A. Villa-Real

Undergraduate Economics Working Paper Series

Las Vegas casino revenue is used as the benchmark to gauge the health of Las Vegas, adjusted to Quarter 1 2014 dollars and using an OLS regression model. The results imply that online sports betting is a poor substitute for Las Vegas revenue, while online gambling shows a positive and statistically significant relationship with revenue. The findings indicate that Las Vegas is resilient despite the introduction of more competition and gambling alternatives within an industry it has traditionally known to …

Gambling Behaviors: How Do Gambling Losses Affect Future Wagers?, Ashley Talavera, Hannah Lopez Ibarra, Roman Rozbitskyy

Undergraduate Economics Working Paper Series

This study looks at how previous gambling losses affect future betting behavior in online cryptocurrency gambling markets. Using roughly 50,000 real betting observations from Bustabit, the paper tests whether gamblers become more aggressive after losses or instead pull back and bet more cautiously. Using both OLS and Fixed Effects regression models, the results show that players generally reduce their wager sizes following losses rather than engage in strong loss-chasing behavior. After controlling for individual player tendencies, the Fixed Effects models show statistically significant decreases in future bet sizes after losses, suggesting that caution and loss aversion may play a larger …

Determinants Of March Madness Tournament Advancement, Jace Waldahl

Undergraduate Economics Working Paper Series

This paper examines whether tournament seed and team efficiency ratings help explain how far teams advance in the NCAA men's basketball tournament. Using Bart Torvik NCAA basketball ratings data from 2008 to 2025, I construct a team-year dataset with tournament advancement measured from 1 to 7, where higher values represent deeper runs. The main independent variables are seed, net efficiency, offensive efficiency, and defensive efficiency. Descriptive statistics, correlations, scatterplots, and OLS regressions are used to test whether better-seeded and more efficient teams advance further. The results show that seed is the strongest and most consistent predictor of advancement, but efficiency …
