Analysis of the Influence of Thread Parameter Deviation on The Sealing Performance of Drill Pipe Joint Under Axial Load
Authors: Cheng Xiaofeng , Hou Yongjun
Published: April 2024

To explore the influence of the limit deviation of the thread parameters of the drill pipe joint on its sealing performance, based on the API NC38 drill pipe joint, the existence of the limit deviations of the three thread parameters of taper, side angle, and pitch is analyzed. Based on this, a total of 12 finite element models of drill pipe joints including various limit deviations and free combinations of internal and external thread limit deviations are established, and the sealing performance of different structures under the action of make-up torque and axial load is analyzed. The results show that the pitch limit deviation has the most obvious influence on the sealing performance of the drill pipe joint, and the yield failure of the contact surface is easy to occur. The existence of taper limit deviation makes the sealing performance of the drill pipe joint significantly reduced when subjected to tensile load. When the change of the limit deviation of the side angle of the internal and external thread teeth is opposite, the plastic deformation occurs locally in the drill pipe joint, which affects the sealing effect. Therefore, it is necessary to control further the tolerance range of the thread parameters of the drill pipe joint to reduce the risk of sealing failure of the drill pipe joint.

In the current context of increasing global light pollution, we urgently need an effective control system. In this study, we constructed an extensive and objective evaluation model through the AHP method to classify light pollution into standard and index layers, and successfully established an evaluation model that accurately predicts the level of light pollution. Through practical tests, we found that light pollution is higher in cities, followed by suburbs, and lower in rural areas and protected areas. Based on the established evaluation model, we propose three most effective intervention strategies: regulating the use of LED billboards, reducing the use of reflective building materials, and controlling nighttime construction lighting. In response to the possible negative impacts, we propose specific solutions and verify the effectiveness of the intervention programs through a multi-objective planning model, achieving significant results in reducing light pollution levels.

A new method of ship detection in complex background of SAR images based on YOLO
Authors: Zhang Xinyu , Huo Hua
Published: April 2024

Synthetic Aperture Radar (SAR) is a remote sensing technology capable of high-resolution imaging of the ground surface under any weather and light conditions. SAR image ship detection is a technique that uses the ship target features in SAR images to identify and locate ships, which is of great value for applications in the fields of maritime traffic management, marine environment monitoring, and maritime security and defence. However, SAR image ship detection also faces some challenges, such as complex sea surface background, low signal-to-noise ratio, and the diversity and density of ship targets, which lead to the shortcomings of traditional feature extraction and classifier-based detection methods in terms of accuracy and efficiency. To address these challenges, this paper proposes a new method for ship detection in SAR images based on YOLOv7. When dealing with SAR images containing clutter interference and complex backgrounds, many models face the dual challenge of insufficient real-time and accuracy. To address this problem, this study proposes a new PCAN aggregation network, which firstly introduces the SimAM attention mechanism, which significantly enhances the model's ability to identify the differences between ships and background clutter, further improves the ability of focusing on target features, and effectively It further improves the ability to focus on target features, effectively reduces the interference of background noise, and improves the detection accuracy in complex scenes. At the same time, the PConv strategy is added to further lighten the model structure, thus accelerating the computation process and improving the inference efficiency. We trained and tested the model on the SAR-Ship-Dataset dataset, and achieved an accuracy of 91.1%, an F1 score of 92.9, and an FPS of 46, demonstrating its excellent detection capability. By comparing and analysing the model with several classical and cutting-edge methods in the current field, the proposed model in this study demonstrates obvious performance advantages, and in addition, through ablation experiments, we further confirm the effectiveness and contribution of PCAN.

Enhanced Thermoelectric Performance in Ca-doped AgSbTe2
Authors: Pan Yi
Published: April 2024

Thermoelectric materials play a crucial role in applications such as recovering waste heat and refrigeration. We report a thermoelectric figure of merit (zT) of 1.17 at 623 K for AgSb1-xCaxTe2, representing a 31% enhancement compared to pristine AgSbTe2. The improved thermoelectric performance arises from enhancements in both the power factor and lattice thermal conductivity. Dopant substitution of element Ca at the Sb site in AgSbTe2 suppresses the formation of Ag2Te and increases the concentration of p-type charge carriers, leading to enhanced electrical transport properties. Additionally, Ca doping introduces solid solution point defects that enhance phonon scattering, consequently reducing the lattice thermal conductivity of the sample. This work demonstrates that a doping effectively modulates the electrical and thermal transport properties of AgSbTe2, thereby realizing improvements in thermoelectric performance.

Comparative view of Sandel's Distributive Justice Theory
Authors: Yao Ruoyu
Published: April 2024

In Western political thought, distributive justice has always been an important issue. Utilitarianism, liberalism and communitarianism represent three different views of distributive justice, but they try to solve the same problem, the inequality of income and wealth. Utilitarianism aims at welfare maximization, liberalism takes respect for freedom as its starting point, and communitarianism, represented by Sandel and MacIntyre, advocates Aristotle's deserved theory with the aim of promoting virtue and taking unity as the banner against inequality. This paper takes Sandel's Liberalism and the Limits of Justice as the core of the study, captures the central proposition of distributive justice from the standpoint of communitarianism, introduces the Marxist distributive justice principles of Marx and Cohen, and compares and interprets the characteristics of Sandel's communitarian distributive justice theory from a perspective different from utilitarianism and liberalism. Finally, based on the principles of Marxist view of justice, this paper briefly expounds the theoretical value, limitation and practical possibility of Sandel's distributive justice theory and communitarian view.

Land Use Change and Ecological Security Evaluation in Haikou City
Authors: Wen Tingting , Yang Xiao
Published: April 2024

With the continuous development of society and the acceleration of urbanization, profound changes have occurred in the utilization of land resources. Unreasonable land use and development pose serious threats to land ecological security, leading to a series of ecological security issues that constrain regional sustainable development. This study takes Haikou City as the research object and utilizes remote sensing (RS) and geographic information system (GIS) technologies to analyze the changes in land use in Haikou City from 2002 to 2022. Simultaneously, a land ecological security evaluation system is constructed based on the "Pressure-State-Response" (PSR) model. The weights of the indicators are determined by combining the Entropy weight method and the analytic hierarchy process (AHP). The TOPSIS (technique for order performance by similarity to ideal solution) method is then applied to evaluate the land ecological security index. The results indicate that during the period from 2002 to 2022, the cropland and impervious areas in Haikou City exhibited significant growth trends, while the areas of grassland, water, barren land, and forest decreased. Despite this, the comprehensive ecological security index of Haikou City showed an overall fluctuating upward trend, reaching its optimal state in 2022, with the land ecological security level improving from "Minor Warning" to "Relatively Safe". These research findings provide scientific evidence for adjusting land use policies and formulating relevant measures, and also serve as an important reference for promoting the sustainable utilization and ecological security protection of land resources in Haikou City.

Authors: Lai Kunning , Huang Sibo , Cui Han , Cheng Yong , Luo Wei
Published: April 2024

This paper introduces an improved PP-YOLO network method to enhance the accuracy of rebar end identification and counting in construction engineering. The network is optimized for the specific characteristics of rebar images, enhancing its recognition capabilities for rebars of various sizes and shapes. Notably, the network structure introduces new pathways in the 4th and 5th layers, enabling more effective learning and identification of rebar features from low-level characteristics, thus improving overall recognition and counting accuracy. Additionally, an optimized data augmentation strategy, tailored to the unique features of rebar images, replaces the traditional Mixup method. Specific algorithms are introduced to enhance the network's efficiency in learning rebar image characteristics. These improvements led to excellent performance in rebar end face recognition tests, achieving an average precision (AP) of 96.23%, a 1.07% increase compared to the original model. This significant performance improvement confirms the effectiveness of our proposed improvements in practical applications, offering new perspectives for the development of rebar detection technology in the construction industry.
A Reflective Object Reconstruction Method Based on Neural Radiance Field
Authors: Li Lifen , Yu Zhengqin , Zhang Ronghua
Published: April 2024

We propose a neural rendering-based 3D reconstruction method for reconstructing the geometry and BRDF of reflective objects from multi-view images captured in unknown environments. Multi-view reconstruction of reflective objects is extremely challenging because specular reflections are view-dependent and therefore violate multi-view consistency, which is the cornerstone of most multi-view reconstruction methods. Recent neural rendering techniques can model the interaction between ambient light and object surfaces to adapt to view-dependent reflections, making it possible to reconstruct reflective objects from multi-view images. However, accurately modeling ambient light in neural rendering is difficult. We propose a two-step approach to solve this problem. First, by introducing view-dependent photometric losses, our method accurately reconstructs the geometry of reflective objects. Then, with the object geometry fixed, we use more accurate sampling to recover the BRDF of the ambient light and object. Experiments show that our method is able to accurately reconstruct the geometry and BRDF of reflective objects from only RGB images without knowing the ambient light and object masks.

Static crushing agent (SCA) has the advantages of good safety, no harmful gas and no vibration. It is widely used in rock crushing engineering of mine or underground engineering. Aiming at the performance of static crushing agent with different water-cement ratios, based on the engineering and environmental conditions of roadway side protection in a mine of Shanxi coking coal, the stress-time curve of SCA and the fracturing law of SCA on roadway side rock under the condition of multi-row drilling were studied by means of laboratory test and numerical simulation. The results show that: the smaller the hole spacing, the better the fracturing effect of SCA, the smaller the required fracture initiation stress and penetration stress, and the existence of the free surface contributes to the development of the fracture, and the fracture around the hole extends along the direction of the incoming pressure under the peripheral pressure conditions; the porous SCA fracturing can be used for the high efficiency of underground rock fracturing projects such as rocky roadway spreading and other underground rock fracturing projects. The research results of the project provide a new method for non-blasting roadway expansion, roof picking and other rock-breaking projects in underground coal mines.
