Research on Prediction of Checked-baggage Departed from Airport Terminal Based on Time Series Analysis 基于时间序列分析的机场航站楼托运行李离港预测研究
Qun Ma, Jun Bi, Qiu Sai, Ziyu Li
Checking baggage for passengers is an important part of the check-in process, which efficiency directly affects the duration when passengers stay in the airport. Predicting the amount of baggage and allocating human resources rationally can help improve the efficiency of airport operations. The amount distribution characteristics of the checked-baggage demand is analyzed based on the actual operating data of the airport in this study. A long-term prediction model based on the multiplicative seasonal model (SARIMA) is built to predict the baggage amount. Results show that the SARIMA model can describe the characteristics of time series, which has high prediction accuracy and strong robustness.

Petroleum Software License Usage Forecast Based On ARIMA Algorithm 基于ARIMA算法的石油软件许可证使用预测
Mengxin Song, Mei Feng, Hongping Miao
In petroleum industry, the expensive software license procurement costs have brought a heavy burden to enterprises. When purchasing the software license, the license management department usually forecasts the reservation, warning, purchase quantity and threshold setting of licenses according to experience and factor analysis method. Due to lack of data support and inaccurate forecast, the enterprises always buy insufficient or surplus quantities of license. In order to solve the above problems, and realize intelligent forecast for license needs, we proposed a method for forecasting the license using status based on ARIMA algorithm, and designed a license management system. Through numerical experiments, it is found that compared with the traditional forecast methods and models, due to the enhanced ability to extract random information, it is more suitable for non-stationary license occupancy sequence forecast in most cases, and the forecast is much more accurate as well.
在石油行业,昂贵的软件许可证采购成本给企业带来了沉重的负担。在购买软件许可证时,许可证管理部门通常根据经验和因素分析法对许可证的预订、警告、购买数量和阈值设置进行预测。由于缺乏数据支持和预测不准确,企业购买许可证的数量往往不足或过剩。为了解决上述问题,实现对许可证需求的智能预测,提出了一种基于ARIMA算法的许可证使用状态预测方法,并设计了一个许可证管理系统。通过数值实验发现,与传统的预测方法和模型相比,由于增强了对随机信息的提取能力,在大多数情况下更适合于非平稳的许可证占用顺序预测,预测精度也大大提高。

Metaheuristics Optimization Algorithm to an Optimal Moroccan Diet 最优摩洛哥饮食的元启发式优化算法
K. E. El Moutaouakil, M. Cheggour, S. Chellak, H. Baïzri
In this work, we propose a well-balanced diet basing on very simple quadratic optimization model which controls the lack of favorable nutrients, the excess of unfavorable nutrients, and which minimizes the total glycemic load of the diet. To solve the proposed mathematical model, we call well-known metaheuristic methods: genetic algorithm, firly algorithm, particle swarm algorithm, stochastic fractal search, and moth swarm algorithm with specific operators. The parameters of these algorithms are experimentally chosen. These algorithms have been tested on 176 foods available on the Moroccan market. Firly has shown its superiority over other methods in its ability to quickly design a well-balanced diet with an acceptable glycemic load.
在这项工作中,我们提出了一个基于非常简单的二次优化模型的均衡饮食,该模型控制了有利营养物质的缺乏,不利营养物质的过剩,并使饮食的总血糖负荷最小化。为了求解所提出的数学模型,我们使用了众所周知的元启发式方法:遗传算法、firly算法、粒子群算法、随机分形搜索和带特定算子的飞蛾群算法。实验选择了这些算法的参数。这些算法已经在摩洛哥市场上的176种食品上进行了测试。Firly已经显示出它比其他方法的优越性,因为它能够快速设计出具有可接受的血糖负荷的均衡饮食。

Existence of Mild Solutions for Semi-Linear Measure Driven Equations With Infinite Delay 无穷大时滞半线性测度驱动方程温和解的存在性
Wenjie Liu, S. Xie
In this paper we prove the existence of mild solutions for semi-linear measure driven equations with infinite delay in Banach spaces. We first establish some conclusions about measure of noncompactness and the phase space of axiomatic system. Then we obtain some existence results by using the fixed point theorem. Some restrictive conditions on a priori estimation and compact semigroup are avoided. The results obtained here improve and generalize many know results. An example is given to illustrate our main results.

Xiaohuan Wu, J. Qi, Huanqiang Zhong, Zhongwei Zhao
In the power system of the urban platform, due to the dense urban population, the real-time monitoring and early warning power distribution cabinet system is of great significance to the safety of urban residents and reducing property losses. Therefore, combined with the dense distribution of urban electrical equipment, we designed a brand-new Internet of Things monitoring system that accurately locates the location of each power distribution cabinet in the city. Through the MQTT protocol, it realizes the data transmission between the microcontroller, server and database. On the web side, we use the current mainstream front-end vue. js and back-end SpringBoot framework. Display data in the form of 2D (echarts) and 3D (unity). The data is updated more timely, the display is more diverse, and the readability becomes stronger. Finally, we evaluated the practicability of the system in combination with the specific use situation. When the temperature and humidity reach a critical value, the system will send an early warning signal to the monitor to achieve the final effect.

Is Face Recognition Being Abused?–A Case Study from the Perspective of Personal Privacy 人脸识别被滥用了吗?——个人隐私视角下的个案研究
Jin Zou, Xu Fu, Chi Gong, Yi Shi
With the diversified development of face recognition application, face recognition technology plays an increasingly important role in people's daily life. However, due to the excessive use of face recognition, individual privacy violations and data leakage incidents have begun to emerge, raising concerns that the development of artificial intelligence such as face recognition has its side effects. It seems to be a contradictory condition that a host of people not only desire to enjoy the convenience of technology upgrading, but also want better privacy protection. This paper starts with the application of face recognition in different subjects, analyzes the harm caused by the overuse of face recognition technology through different cases, and finally puts forward corresponding policy suggestions based on the current protection methods of biological information data in different countries.
随着人脸识别应用的多元化发展,人脸识别技术在人们的日常生活中发挥着越来越重要的作用。然而,由于人脸识别的过度使用,个人隐私侵犯和数据泄露事件开始出现,人们担心人脸识别等人工智能的发展有其副作用。许多人既希望享受技术升级带来的便利,又希望得到更好的隐私保护,这似乎是一个矛盾的情况。本文从人脸识别在不同学科中的应用入手,通过不同的案例分析了人脸识别技术被过度使用所带来的危害,最后结合各国目前生物信息数据的保护方式,提出相应的政策建议。

Insight into the Inhibitory Activities of Diverse Ligands for Tyrosinase Using Molecular and Structure-based Features 利用分子和结构特征研究不同配体对酪氨酸酶的抑制活性
Haifeng Tang, Qiuyu Hu, Qin Hu, Aohua Fan, Xiaoguang Chen, Y. Liu
Tyrosinase, which is closely related to blacking fruit and vegetable, larva development and abnormal deposition of melanin inside human skin, distribute broadly in cells of animal, plant and microorganism. Harmless inhibitors of tyrosinase can be used for lengthening storing time of fruits and vegetables, resisting insects in agriculture and cuing stain. Exploration of common pharmacophores of tyrosinase inhibitors provides ways to understand the inhibitory mechanism and design safe inhibitors. In this study, structure-based features based on MM-PBSA method and binding free energy computation were combined with molecular features to setup a descriptive relationship between tyrosinase inhibitory active and molecular structure for 46 diverse ligands. Monte Carlo and random Forest algorithms were used to build regression model for multiple variable and case. Explicit models using Monte Carlo provided 0.66, and implicit models using Random Forest afforded 0.92 for Pearson correlation coefficients (R2). By analyzing the common structure of 46 inhibitors, we found that the hydroxyl in ring B of flavonoid could binding to active site of tyrosinase directly and exhibit strong inhibitory active. Other structure similar with flavonoid could inhibit tyrosinase as well. The inhibitors including 2,4-dihydroxyphenol group at one end of molecular structure show up strongest inhibitory force.
酪氨酸酶广泛存在于动物、植物和微生物细胞中,与果蔬发黑、幼虫发育和人体皮肤黑色素异常沉积密切相关。酪氨酸酶的无害抑制剂可用于延长果蔬贮藏时间、农业上抗虫、防治霉变等。探索常见的酪氨酸酶抑制剂的药效团为理解抑制机制和设计安全的抑制剂提供了途径。本研究将基于MM-PBSA方法和结合自由能计算的结构特征与分子特征相结合,建立了46种不同配体酪氨酸酶抑制活性与分子结构之间的描述性关系。采用蒙特卡罗算法和随机森林算法建立多变量和case的回归模型。蒙特卡罗显式模型的Pearson相关系数(R2)为0.66,随机森林隐式模型的Pearson相关系数(R2)为0.92。通过分析46种抑制剂的共同结构,我们发现类黄酮B环的羟基可以直接结合酪氨酸酶的活性位点,并表现出较强的抑制活性。其他与类黄酮结构相似的化合物也能抑制酪氨酸酶。在分子结构一端含有2,4-二羟基酚基团的抑制剂表现出最强的抑制力。
