An Enhanced Framework for Urban Water Consumption Analysis: Feature Clustering with Ensemble Methods

Faye F.F. Jiang — Sun, 06 Apr 2025 00:00:00 +0800

Urban water consumption analysis presents significant challenges due to the complex interplay of socioeconomic, demographic, and built environment factors. This paper introduces a novel Feature Clustering Framework of TopK and Threshold with Ensemble Method (FCTTE) specifically designed to address high-dimensional urban datasets. We evaluate this framework using a comprehensive dataset of 1,120 features across eight domains related to New York City's urban environment. Our experiments demonstrate that FCTTE significantly outperforms conventional feature selection methods, improving LightGBM classification accuracy by 4.6% compared to baseline, while traditional methods achieved only 1% improvement. The framework identified median family income, energy usage intensity, adult male population, greenhouse gas emissions, and commercial building characteristics as the most influential factors affecting water consumption. By effectively managing feature redundancy through hierarchical clustering and strategic selection, FCTTE provides urban planners with interpretable insights for water resource management while maintaining superior predictive performance. This integrated approach bridges the gap between fragmented analyses of individual urban factors and the need for holistic understanding of water consumption patterns in complex urban environments.

Yangchen Sun — Wed, 16 Apr 2025 00:00:00 +0800

In this paper, Pearson correlation analysis was used to correlate the different mixing ratios of the three pyrolysis combinations with the associated pyrolysis product yields. Then, a paired-sample t-test model was used to explore whether the catalyst DFA plays an important catalytic role in promoting the pyrolysis of CS, CE and LG. In order to address the effect of mixing ratios of pyrolysis combinations on the yields, this paper plotted line graphs with the mixing ratios of pyrolysis combinations as the horizontal axis and the pyrolysis gas yields as the vertical axis, and interpreted the effect of mixing ratios on the yields of each gas according to the trend of each gas.

A Design of Bionic Gripper to Enhance the Persistence of Wild Life Monitoring Performed by Drone

Yuheng Zhang, Yuhang Hu — Fri, 18 Apr 2025 00:00:00 +0800

In recent day, drones has become an essential tools in environmental observation and wildlife animal monitoring. It is undeniable that the effectiveness of this tool is often limited by challenges in landing and energy efficiency, particularly in dense forest environments. To address this potential problems, this study proposes a bionic gripper which is inspired by bird talons for enhancing drone landing capabilities, enabling a stable landing on complex environments for example tree branches. The gripper features a self-locking mechanism, which highly reduces the energy consumption while maintaining a stable and reliable holding. Using SolidWorks and Fusion 360, the gripper was designed and stimulated for a lightweight and adaptive performance. A key application of this technology is in the conservation for endangered species such as crested-ibis. This system is allowing drones to conduct long-term, low-disturbance observation, which not only extends the operation time but also minimizes the interference from noises, that contributes to a more sustainable and effective wildlife research as well as environmental monitoring.

In order to investigate the influence of factors on the spray deposition of the spray bar sprayer, using the designed mobile spray bar spray device, the spray height, spray bar travelling speed and spray pressure were selected as the test factors, and the deposition amount of seductive red per unit blade area Y₁ and the deposition coefficient of variation Y₂ were taken as the evaluation indexes for the test, and the 3-factor, 3-level orthogonal rotary spray deposition test was carried out. The Box-Behnken response surface method was used to analyse and obtain the mathematical model of the spray deposition characteristics of spray height H, spray rod travel speed v and spray pressure P. The influence of each factor on the spray deposition characteristics and the optimal working parameters of the spray machine were obtained according to the regression analysis results. The results show that the forward speed, working height and spray pressure have a significant effect on the spray deposition characteristics, and the degree of influence in the order of the factors from the largest to the smallest is the spray pressure, the working height, the forward speed, the spray pressure, the working height and the spray pressure. The mean value of droplet deposition per unit area is negatively correlated with forward speed and nozzle working height, and positively correlated with spray pressure. The coefficient of variation of deposition is negatively correlated with the spray pressure, positively correlated with the forward speed, and decreases and then increases with the increase of the working height, which indicates that in the case of a certain working height, increasing the spray pressure or reducing the forward speed can effectively improve the uniformity of droplet deposition of the sprayer.

Visible Body Anxiety: The Mediatized Management Practices of Quantifying Body Shapes and Physicality

Xiaotong Shi — Sat, 26 Apr 2025 00:00:00 +0800

The proliferation of fitness and exercise-related social media, applications, and wearable devices has provided individuals with convenient tools for body management. These technological means have enabled the mediatized management of bodies, permeating various aspects of daily life. However, this process has also raised tensions regarding the relationship between individuals and media control. This study adopts media visibility and digital rationality as theoretical perspectives, employing qualitative interviews and participatory observation to explore the impact of fitness applications and devices on users' body management practices. It investigates how users navigate the visible/invisible dichotomy of "highlighting" and "concealing" within the data relationships of "quantifying body shapes." The findings reveal that when users face motivational deficits, they often utilize visual body tracking tools to monitor and record bodily data, enabling real-time observation of bodily changes. While "self-quantification" facilitates body management, it also generates new challenges and anxieties. The prevalence of flow-dominated quantification aesthetics leads users to excessively focus on body image and overly rely on technological tools, thereby neglecting the natural state of the body and self-perception, which may adversely affect users' physical and mental health.

Adaptive Containment Control for Nonlinear Multi-Agent Systems with Input Quantization and Sensor Faults

Wen Wen — Tue, 29 Apr 2025 00:00:00 +0800

This study investigates the adaptive containment control problem for a class of nonlinear multi-agent systems with input quantization and sensor faults. A state observer and a radial basis function neural network are respectively employed to estimate unmeasurable states and approximate unknown nonlinear functions. An absolute cubic Lyapunov function is designed to compensate for the influence of sensor faults on the systems. A filter is introduced to reduce computational complexity. Adaptive laws are developed to update the estimates of uncertain dynamic parameters, fault coefficients, and the filter-error compensation term. A distributed adaptive control scheme is proposed to ensure that all followers converge to the convex hull formed by the leaders. The stability of the closed-loop system is strictly proved based on stability theory, and the effectiveness of the proposed control method is verified by numerical simulation.

To study the reservoir characteristics and main controlling factors of Jurassic Yan'an formation in Hao Tan area of Ordos Basin. The reservoir characteristics and its main controlling factors were revealed by the experimental observations such as rock sheet analysis, high pressure mercury pressure experiment and cathodoluminescence. The Jurassic reservoirs in Hao Tan area are mainly located in Yan 10~Yan 8 section.The results show that the main types are feldspathic sandstone and feldspathic quartz sand with medium to low maturity, and the main types of pores include intergranular pores, intergranular dissolution pores and feldspathic dissolution pores. The physical properties of the reservoir are dominated by mesopore mesoturbidity, with medium throat radius and low drainage pressure. The reservoir has experienced moderate to strong mechanical compaction with various types of cementation dominated by carbonate, siliceous and clay minerals, among which the pore structure of the reservoir has been significantly improved by dissolution. The reservoirs of the Yan'an Formation have certain storage capacity and development potential, especially the Yan 10 and Yan 8 reservoirs have better physical properties, and the sedimentation and diagenesis have affected the inhomogeneity of the reservoirs. It is concluded that the Yan 8 reservoir (72% class II) and the local sweet spot of Yan 10 (class I porosity >16%) have development potential, but different development strategies should be formulated for the high permeability zone of Yan 9. The results of the study can provide a theoretical basis for the exploration and development of the same type of Jurassic tight sandstone reservoirs in the Ordos Basin.
